[Semiconductor Cold Warm Box] Four Questions and Answers on Cold and Warm Boxes on car Cold Box on car Cold Box

In the current domestic market, there are as many companies that produce car refrigerators. Many small manufacturers, cut corners when they produce products, have a bad cooling and heat -making effect. If it is not used properly, it may cause damage to the car battery. ThereforeFriends must choose carefully.Many friends who do not know how to choose the car warm and warm box, they all have such questions, Xiaobian will give answers one by one here!

First, can the car warm and warm box make ice?

If you want to know if you can make ice in the car, you must first figure out its working principle.At present, the most car warm and warm boxes on the market are actually used to refrigerate with semiconductor materials. This material uses the Partia effect to work (please Baidu for children's shoes that do not understand), so the cooling effect may be worse than the compressor.Some, but this does not mean that the car warm and warm box cannot be made of ice.Some manufacturers' products, such as Deng Lupu's car warm and warm box, can still use the powerful refrigeration effect to make ice as long as they are equipped with an ice box and a partition.

Second, what are the attention of the Car refrigerator in daily use?

Many of the car refrigerators need to pay attention in daily use. First of all, it must be kept clean, especially at the ventilated port, because the heat inside the refrigerator is released here, and it will be troublesome if it is blocked.There are also daily cleaning and scrubbing with neutral soap and wet cloth. Do not insert electricity.The second is about temperature. It is best not to put very hot food into the Car refrigerator. In addition, because the power of the Car refrigerator is small, the refrigeration effect will not be as goodDrinking ice cold drinks when walking, it is recommended to refrigerate in the refrigerator first, and then put it in the Car refrigerator, which will be much better.

Third, will the Car refrigerator hurt the car battery?

Of course not.The power of the Car refrigerator is very small and generally does not exceed 100W. Such a small power cannot cause damage to the car battery.However, the owner should also pay attention to the daily use that the ordinary car thermal box, it is best not to use it for a long time after the car is stopped, which may cause the battery to put it.Therefore, when buying consumers, pay attention to choosing products with low -pressure protection functions, so that if you accidentally forget to pull out the cigarette barrel, it will not cause the car battery to put it.

Fourth, can the Car refrigerator be used at home?

Yes, but you need to be equipped with a home power converter.The function of the household power converter is to convert the voltage of 220V into a 12V voltage. With this thing, it can be used.

car warm and warm box

The car warm and warm box uses electronic refrigeration and heating technology, which is polluted and environmentally friendly. It can be placed on a seat or floor in the car. You can easily and conveniently put food at will. It has dual functions of refrigeration and heat.

[Hot and warm box purchase] Which type of cool and warm box is better to use the warm and warm box to buy guidelines

The advantages and disadvantages of semiconductor refrigeration (heat)

1. Volume and cost.No compressor is required, not only is the volume and small costs very low, but it can be reflected and heated.

2. Refrigeration temperature and heating temperature.Most of the minimum refrigeration temperature is about 6 degrees Celsius; the temperature difference between the minimum temperature and the environmental temperature does not exceed 20-25 degrees Celsius; the maximum heating temperature is about 65 degrees Celsius.

Large and medium vehicles can choose to compress the model Car refrigerator

1. RV, bus, and business models are larger. For large and medium -sized vehicles with larger compartment, if you need to be stronger, faster, and more constant, the refrigeration performance is required.The Car refrigerator is the first choice.

2. Power interface.Large and medium -sized vehicles are sufficient, and can even provide 220V standard power port and power output power above 500W.

3. Compressed models of car refrigerators usually have no heating function.

Don't ignore the thermal insulation and heating function

1. Thermal insulation effect.The cabinet of the car's warm and warm box is thick and good thermal insulation performance, and it should have good thermal insulation (cold) performance.

2. The heating function is more practical.In winter, many regions do not need to refrigerate (the trunk is an excellent "refrigerator"), but enjoying a hot food and drinks in the itinerary often become extravagant.The insulation and heating function of the car warm and warm box uses the place where it is displayed at this time.3. Heating is more efficient than cooling.Fortunately, the heating speed of the car warm and warm box is relatively faster and more efficient, and the temperature limit of the maximum 65 degrees Celsius is enough to meet daily needs.

The relationship between capacity, refrigeration speed and power

1. The larger the capacity, the slower the cooling (thermal).For example, for example: 60W power 4 -liter of mini warm and warm box. At the temperature of 28 degrees Celsius, the temperature in the box (empty box) can be reduced to 6 degrees Celsius in about 3 small, but if it is also 60W power 8 liters, if it is also 60W power 8 liters, 8 liters of power 8 litersThe cooling and warm box of capacity may take more than 6 hours to fall to 6 degrees Celsius.

2. The smaller the power, the slower the cooling (thermal).Play another less accurate analogy: a 60W power 4 -liter mini warm and warm box. If it is 3 hours of refrigeration to 6 degrees Celsius, if it is replaced by 30W power, this time may be extended to more than 6 hours (Little Mara Grandcar).

3. Cold and warm boxes with small capacity and high power.In order to ensure good refrigeration efficiency, under the premise of sufficient capacity, high -power, small -capacity warm and warm box may be the best choice.

Factors affecting cooling (thermal) efficiency

1. Environmental temperature.The higher the ambient temperature, the slower the cooling speed of the car in the car, and the faster the heating speed; vice versa.

2. The items to be stored.If a bottle of boiling water wants to refrigerate, the effect of putting in the car hot and warm box is not as effective as opening the bottle cap for a few hours; if it is a piece of ice, if you want to be discharged, the effect of putting in the car warm and warm box may be in the sun.The difference is not much different.

3. Pre -cold (hot) food and drink.In order to achieve rapid and efficient cooling or heating, it is necessary to put food that need to be refrigerated in advance in the home refrigerator in advance, or heat the food that needs heating in advance in the microwave oven, which can achieve faster, more efficient, more efficient, more efficient, more efficientConstant cooling or heating effect.

4. It is strongly recommended to use ice Bags or iced bottles of water to assist cold, which is more efficient and more constant.

The necessity of the car family dual -use warm and warm box

1. Innonal air is not that you can come.Many car owners complain that the cooling speed of the car warm and warm box is slow. It is known that a bottle of constant warm water is placed in the Car refrigerator for 1 hour and has not changed much.The slow cooling speed is indeed the embarrassment of the car warm and warm box, which is also the time when the advantages of the cool and cold box of the car family.Housewriters can be used on the car or connect to the ordinary power supply at home, which can be used at home. It can work almost in any place with a power supply to maximize the temperature loss and fluctuations caused by power interruption.

2. Use the car warm and warm box in the home environment.The working principle of the car warm and warm box is similar to that kind of refrigerated heat -made dual -use water dispenser. If necessary, you can use the car warm and warm box in the home environment through the power transferor, which makes the advantages of the dual -use of the car.Essence

Introduction to thermal insulation water tank

What is the insulation water tank

The insulation water tank refers to the addition of special industries and thermal insulation materials in the mezzanine of the water tank, so that the water tank must maintain a certain temperature to meet the needs of life or industrial.The insulation water tank can be divided into: stainless steel insulation water tank, pressure insulation water tank, and glass fiber reinforcement heating water tank according to the different processing materials.

The principle and structural diagram of thermal insulation water tank

The insulation water tank refers to a kind of insulation material used in the inside of the insulation cup to make the core layer, and then use the stainless steel water tank as the inner surface layer, and the outer layer is made of ordinary stainless steel plates.The combination of these three materials is the most suitable and best combination. In this way, the stainless steel insulation water tank is initially formed.Therefore, the insulation water tank is composed of three layers, the core layer, inner layer and outer layer.

The insulation medium of the core layer can be insulated by 50mm or 80mm polyurethane foam, polystyrene, PEF, etc.The inner layer is a stainless steel layer, so it is necessary to use a better -quality SUS304 food -grade stainless steel plate and galvanized plate.Finally, the outer layer is generally selected by the relatively ordinary stainless steel punching film block or a tablet. You can choose SUS304 stainless steel or SUS201 stainless steel for production! The thickness of the water tank board can be determined according to the size and height of the water tank.Of course, the material for insulation can also be used to choose asbestos or rock wools for insulation.

The insulation water tank hot water is out of the hot water

under.The insulation water tank consists of three parts: high water tank, depository and low water tank.The high water tank is equipped with a mechanical controlling water moisturizer, flushing valve and water leak valve, and electrode floating sub -switch. The valve seats of the water moisturizer and flushing valve are connected to the three -way flushing pipes set in the storage tank.Open the valve, connect the high water tank with the water storage tank; set up leveraged float switches in the low water tank, open the float valve core, connect the water tank with the low water tank; there are also submersible pumps, filters and sewage pipes in the low water tank, submersible pump out of the water pipe out of the water tankThe mouth is located in the high water tank, and the closure of the submersible pump is controlled by the electrode float switch in the high water tank.

How long can you keep the insulation in the thermal insulation?

Looking at the performance of the insulation water tank, at room temperature (20-30 degrees), the thermal insulation water tanks dropped by about five degrees within 24 hours. The lower the external temperature, the lower the temperature decrease of the water temperature.

Insulation water tank classification

Advantages: It is mainly divided into enamel water tanks and stainless steel pressure tanks; enamel water tanks are not easy to be corroded; stainless steel pressing water tanks will be very durable as long as the anti -corrosion problem is solved, and the overall is very light, convenient for transportation. At the same time, it can be designed in the overall structure.More big.

Disadvantages: As long as the temperature difference between enamel water tanks changes, porcelain will be dropped, and the water tank cannot be done too much, and there are certain problems in the handling of the transportation.If the design is not good, the corrosion will occur, and leakage will occur.

FRP insulation water tank

Advantages: easy installation, saving space, no leakage, light weight, high strength, impact resistance, bending, easy repair.

Disadvantages: It can only be stored in warm water and cannot store hot water; the sealing is not good enough, and it is easy to produce secondary pollution; the service life is short, and it is prone to cracks when using 1.5-3.5 years.

Solar insulation water tank

Advantages: The system has good thermal insulation. As long as there is hot water in the water tank, the phenomenon of heat and coldness will not occur; if the service life is long, the use of reasonable life can be as long as 15 years.

Disadvantages: The requirements for the installation location are very strict. If the installation is improper, there will be hidden safety hazards.Hours of hot water supply, poor comfort.

Thermal insulation water tank price

Generally, the price of heating water tanks from 0.5T-10T is more than 1,000 yuan-9,000 yuan. The larger the volume, the larger the capacity, the more expensive the price, and the price is different from the thickness of the insulation layer, the material of the inner and outer Skin, and the price is also different.

Self -made insulation water tank

What materials need

Stainless steel insulation water tank insulation material: Core layer medium can use polyurethane foam, polystyrene, polybionenitine, rock wool, PEF.The inner layer can be used for food -grade stainless steel plates, galvanized plates, aluminum plates or color steel plates.The outer layer can be made of stainless steel plates, galvanized plates, aluminum plates or color steel plates with general materials.
