[Warm and warm box repair] What should I do if the car heating box does not work?

What should I do if the hot and cold box does not work?

First check whether the status indicates whether it is normal (models with refrigeration and heating indicator Lights); if the indicator light is not bright, or the indicator light is sometimes light and sometimes not bright, mostly the problem of power connection.Can be solved by the following methods:

1. The main power switch on the car is not turned on, because on most vehicles, the key switch is turned on before the smoke socket will be powered on.

2. For the situation where it is too loose, you should be inserted slightly;

3. Smoke sockets or warm and warm box electrical line plugs are dirty, and the refrigerator must be connected after cleaning. Otherwise, it will cause overheating due to poor contact.

4. The fuse in the cigarette socket or the warm and warm box electric source line is burned, and the same model of the specifications should be replaced.

5. The cooling and cold box refrigeration heat conversion switch caused poor contact due to dirt.You can remove the power first and quickly mobilize the switch back and forth several times. You can also clean or send it by yourself.

6. View whether the cooling and warm box heat dissipation fan is Running normally. The fan does not turn or the speed is too slow. The heating box will not be able to refrigerate, but the heating function is normal.

7. When the power supply and switch are no problem and the fan is normal, it may be that the refrigerator is damaged and the maintenance point must be replaced.

The cooling effect of semiconductor refrigerators is not good, how to solve it?

If the extension line is too long, the input voltage will be too low, which will affect the cooling effect.

Poor ventilation can also affect the refrigeration effect, you can adjust the positioning position;

Too much dust affects heat dissipation: leading to poor refrigeration.You can guide the dust on the radiator and the fan on the instructions.

For products with fans inside the warm and warm box, keep the air offer open.

Slow refrigeration: You can put drinks or foods in the home refrigerator and refrigerate before putting it in the warm and warm box. The temperature in the box can maintain it at 15 C-20 C than the ambient temperature after plug-in.

precautions for the use of semiconductor refrigeration products:

Semiconductor electronic boxes can only cool or heat, cannot make ice, cannot be used to store frozen foods such as ice cream, and do not have a refrigerator -like refrigerator like a compressor refrigerator.

The semiconductor electronic box can only be reduced to a temperature lower than the ambient temperature of 20 C-25 C, and the minimum energy refrigeration to 5 C, but it does not mean that when the ambient temperature is 10 C, the box can be reduced to -10 C.(When some models are lower than 15 degrees, there may be frosty)

Please keep the ventilated port and heat dissipation holes in the Car refrigerator, and pay attention to cleaning the dust on the fan or dust cover in time;

Do not stuff the items into the Car refrigerator's heat sink and air inlet pores, and the Car refrigerator should be away from the heat source.

When the heating function and the refrigeration function are converted, the power must be turned off, and the refrigerator is started after 5 minutes.

When cleaning the Car refrigerator, turn off all the power supply, do not use hard objects and powerful cleaners to clean the refrigerator.

When the semiconductor refrigeration products are large or storage of moisture -containing items, condensate water can also be produced, and you can wipe it.

How long is the service life of the semiconductor refrigerator?

The service life of the semiconductor refrigerator is generally about 3 years (note: the normal service life of semiconductor refrigeration tablets is more than 100,000 hours, and the life of components such as fans is generally 1 to 3 years), which are different due to different use environment.

[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.

It specially involves suitable for car supporting. It includes the main body of the warm and warm box, the tray, and the two -way plug.

[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
