What is a car refrigerator? Introduction to Car Refrigerator

Car owners are not unfamiliar with car refrigerators. They are refrigerators placed in cars, which are particularly convenient. If you were asked to provide some details about car refrigerators, how much knowledge could you introduce? It's okay if we're not sure. Now let's briefly introduce what a car refrigerator is and some introductions to car refrigerators. What is a car refrigerator? It is a portable refrigerator directly connected to the car power supply, with small size, low noise, vibration resistance and impact resistance, but relatively high cost. It is mostly equipped in luxury cars, usually located behind the center armrest of the rear seats, and some car models' car refrigerators are located below the front center armrest. Introduction to Car Refrigerator 1. Car refrigerators are a continuation of household refrigerators, which can use semiconductor electronic refrigeration technology or be cooled by compressors. Generally, there is little noise and pollution. Just plug the power plug into the cigarette lighter during driving to cool the refrigerator. 2. Vehicle insulation boxes are not truly automotive electrical products because they do not have refrigeration capacity. The car insulation box is a car insulation box produced with insulation materials as interlayer, which is more suitable for short-term use to maintain the temperature of food (including cold and warm). 3. The compressor type car refrigerator is a powerful car refrigerator. Compared with the two types of car refrigerators mentioned above, it has advantages such as strong cooling capacity, large volume, and convenient use; However, the disadvantages of compressor type car refrigerators are also quite obvious: they have large volume, high weight, difficulty in handling, high usage costs, and the purchase price is much higher than the first two. 4. Semiconductor car refrigerator: It relies on electronic chips for cooling, with the advantages of being both cooling and heating, environmentally friendly, pollution-free, small in size, low in cost, no vibration or noise during operation, and long in service life. The disadvantage is low refrigeration efficiency and small capacity. 5. The temperature control range of car refrigerators also needs to be determined based on the actual situation of use when selecting, and it is not necessarily better for car refrigerators with the lowest temperature. Of course, when it comes to the sealing performance of car refrigerators, it also needs to be carefully considered, as this not only affects the operation effect, but also relates to the hygiene of the things stored inside. The above is an introduction to car refrigerators. If you are concerned about the battery cost of car refrigerators, you can choose a refrigerator with an automatic power off function. I hope this article can provide you with some help.

Precautions for car refrigerators

1. Car refrigerators must be aware of their low cooling temperature. Semiconductor car refrigerators do not have significant cooling effects, and their cooling speed is slow. They are used to store frozen or frozen items in household refrigerators before moving them in. 2. When purchasing a car refrigerator, choose a product with low voltage protection function. 3. It can be equipped with a power converter to ensure both home and car use of the refrigerator. 4. When using a car refrigerator, try to avoid water entering the air inlet, otherwise the car refrigerator will strike. 5. Magnetic objects should not be placed in the inner container of the refrigerator to prevent the internal cooling chip from being affected. 6. Do not place overheated or corrosive objects inside the box to avoid damage to the inner container. 7. When switching from one temperature mode to another, the semiconductor car refrigerator needs to cut off the power supply for 8-10 minutes. 8. When using a car refrigerator without a low-voltage packaging device, remember to cut off the power supply of the product after turning off the engine. 9. Each refrigerator has air vents for heat dissipation, so be careful not to block the air vents when placing them.

What are the differences between car refrigerators and household refrigerators

There are some significant differences between car refrigerators and household refrigerators, mainly including the following aspects: 1. Overall dimensions and weight: Car refrigerators are usually smaller and lighter than household refrigerators to meet vehicle space limitations and mobility needs. Most car refrigerators have a capacity of around 20 to 60 liters, while most household refrigerators typically have a capacity of over 100 liters. 2. Power Requirements: The power supply for car refrigerators is generally 12 volts (DC), which needs to be used in conjunction with car batteries or other adapters. Household refrigerators use a 220 volt AC power supply. 3. Working environment: The car refrigerator needs to withstand harsh working environment tests such as ups and downs, vibrations, and high temperatures, so its design has characteristics such as shock resistance, drop resistance, and heat insulation. However, household refrigerators are located in a relatively constant and stable indoor environment, and there are no such problems. 4. Power consumption: Due to the need to use car batteries for power supply in car refrigerators, their power is relatively low, usually around 30 to 80 watts; The power of household refrigerators is generally between 150 watts and 300 watts. Meanwhile, due to the fact that car refrigerators rely on car batteries to operate, their usage time is limited by battery capacity and charging conditions. In summary, there are significant differences in size, power requirements, working environment, and power consumption between car refrigerators and household refrigerators. Choose suitable products based on the actual needs of different demand scenarios.

The structure of electric window regulators for automobiles

Car door and window glass should not only ensure that the driver has sufficient perspective to safely drive and drive; At the same time, in order to meet the needs of riding comfort, the position of the glass often needs to be adjusted, so the range of glass adjustment and the flexibility and convenience of operation become important performance indicators. The mechanism that ensures flexible adjustment of car windows is the window regulator, which is also an important component for car safety and comfort. Structure and characteristics of car window regulator In 1981, China implemented the JB2882-81 "Technical Conditions 8 Standard for Glass Lifts for Heavy Duty Vehicles". Based on this standard, and based on the manufacturing, use, and testing situation of glass Lifts for automobiles in China, and referring to relevant international advanced technical indicators and data, the automotive industry standards QC/T29026-91 "Test Methods for Glass Lifts for Automobiles" and QCT29027-91 were revised and formulated The "Technical Conditions for Automotive Glass Lifter" was promulgated and implemented in 1991, which clearly stipulates the basic technical performance and testing methods of automotive glass lifters. Due to the widespread use of arm type glass lifters in China, other types, especially flexible glass lifters, lack relevant technical information and data. Therefore, the above standards are only applicable to arm type glass lifters, and other types of glass lifters The descent device can also be executed as a reference. Due to the relatively simple manufacturing process and low cost of arm type window regulators, about 80% of car window regulators in China currently use arm type window regulators. The flexible glass regulator is much more compact in terms of stability and motion resistance, and is more convenient to install and arrange. However, there is currently no official national standard for flexible glass regulators in China. The flexible shaft type window regulator has been widely used in various high-end vehicles, especially sedans, around the world, and is a relatively advanced type of window regulator. In recent years, imported automotive products in China, such as CNHTC Steyr, Beijing Cherokee, and Nanjing Iveco, have all adopted this type of opening and lowering device. Currently, some automotive parts factories in China, such as Beijing Automotive Window Lifter Factory, Nanqi Vehicle Tool Factory, and Sichuan Automotive Factory Accessory Factory, have completed the technical development (introduction) of the production process for flexible shaft glass regulators, providing domestically produced products. With the improvement of their mass production level, It can also be used as an alternative to arm type window regulators. Due to the requirements of automotive structural layout design, manufacturing costs, and manufacturing technology, manual push-pull window adjustment mechanisms are still used in many vehicles. At present, arm and manual (mechanical) window regulators are the main types of use, while the application of flexible window regulators is still limited to imported models, while the application of electric window regulators is relatively limited. The application of electric window regulators in mid to high-end cars abroad is already very common. However, due to its complex structure, high cost, and unstable performance of small motor products in China, its application in automotive products in China is still limited. It can be foreseen that with the improvement of China's automotive design and manufacturing level, electric window regulators will be increasingly applied to automotive products.
