Car refrigerator category

A wide range of car refrigerators are divided into the following categories:

Semi-conductor electronic refrigeration Car refrigerator The semiconductor refrigerator has two functions of cooling and heating: In the aspect of refrigeration, it is generally lower than the ambient temperature of 10 ~ 15 °C, and its heating temperature can be as high as 65 °C; In addition, because the compressor is not used, Semiconductor refrigerators also have the advantages of energy saving, environmental protection, noiselessness, and light weight. The market price is between RMB 200 and RMB 1,000. This kind of semi-conductor electronic refrigeration car refrigerator has the advantages of relatively cheap price and convenient use. The disadvantage is that the cooling temperature is not low enough. In the hot summer, the internal temperature of the semiconductor electronic refrigeration car refrigerator is generally about 15 degrees Celsius, which can only give a little coolness. , And semiconductor electronic refrigeration car refrigerator can not be cooled off the car power supply.

Principles Semiconductor electronic refrigeration, also known as thermoelectric refrigeration, or thermoelectric cooling, is a cooling method that uses the "Peltier effect," and compression-type refrigeration and absorption refrigeration, and is called the world's three largest refrigeration methods. In 1843, the French physicist Peltier received a tantalum wire at both ends of the copper wire, and then connected the two tantalum wires to the positive and negative poles of the DC power supply. After powering on, he was surprised to find that a connector became hot. The other joint became cold; this phenomenon was later called the Peltier effect. The physical principle of the Peltier effect is that a charge carrier moves in a conductor to form an electric current. Since the charge carrier is in different energy levels in different materials, when it moves from a high energy level to a low level, it releases excess. The heat. On the contrary, it needs to absorb heat from outside (that is, it shows cooling).

The simple structure of the structural electronic refrigerator is that the P-type semiconductor, the N-type semiconductor, and the copper plate and the copper wire are connected into a loop, and the copper plate and the wire only play a conductive role, and the loop is powered by the 12V direct current. After the current is turned on, one of the contacts is cooled ( The inside of the refrigerator, the other connector cooling (heatsink behind the refrigerator).

Features 1, simple structure, fewer parts, easy maintenance;
2, no mechanical transmission parts, no wear, no noise, long life;
3, without refrigerant refrigeration (both compression and absorption), absolutely environmental protection;
4, high efficiency, low power consumption (under 100W, power consumption is only half of the compression and absorption.

Scope of application Suitable for both cars and households. Suitable for fresh-keeping storage and insulation of beverages, foods, fruits, milk, red wine, and low-temperature medicines. It is home, hotels, offices, bars, student apartments, and driving (trucks, taxis, passenger cars, coaches), tourism, picnics, The best partner for camping and fishing.

Energy-storage plate cooling Passive car refrigerator This type of refrigerator does not consume electricity, and of course it will not dissipate heat inside the car, reducing the heat source in the car. Before use, just put the ice bag in the refrigerator into the household refrigerator to fully refrigerate, and then put the ice bag into the car refrigerator to cool it. It is very convenient to use, and generally can maintain the low temperature for more than 72 hours. In the winter, if the ice bag is put into the microwave oven and heated sufficiently and put into the car refrigerator, it can also play a role in keeping warm. This kind of passive refrigerator can avoid the noise generated when the compressor is working, and it also has the characteristics of energy-saving, environmental protection, noiseless, light and flexible semiconductor refrigerator, and is expected to occupy a place in the car refrigerator market.

At present, according to market demand, there have been introduced refrigerators and refrigerators of two types. By purchasing different energy storage boxes, customers can have both passive and frozen refrigerators. Refrigerated passive car refrigerators are mainly designed for foods, beverages, snacks, etc. that need to be refrigerated. The cooling temperature is about 2-8 degrees. The frozen-type passive vehicle-mounted refrigerator is mainly intended for foods such as ice cream and shaved ice that need to be frozen. At present, Alessi’s passive refrigerator models are available in 7-liter, 12-liter, and 26-liter models.

The advantages of energy-storage plate refrigeration passive vehicle-mounted refrigerators are that they are cheap and the cooling temperature is lower than that of semiconductor electronic refrigeration car refrigerators. The disadvantage is that the energy storage plate must be frozen and cooled in the freezer of the refrigerator before use. Therefore, it cannot be used. It is not very convenient to leave the refrigerator for too long.

Compressor Refrigeration Refrigerator Compressor The refrigerator has only cooling function. Its cooling capacity can reach 18°C. It can control temperature in sections and is not easy to damage. It can be used for cooling in a stable and effective manner. It is used in many high-end cars and standard cars. Compressor refrigerator, the market price is more than 10 times the same volume semiconductor refrigerator.

At present, apart from Germany, Meigu and Kelon have invested in the compressor refrigerator production line in China, the rest of the manufacturers are relying on semiconductor refrigerators to hit the market. According to the latest news from the relevant channels, Haier is also actively launching a compressor-free refrigerator production line. It is expected that by 2008, GE and other well-known auto companies will be able to supply "standard".

Compressor Refrigeration The advantage of a car refrigerator is that the refrigeration temperature is low. The disadvantage is that the price is relatively high. It can't continue to be cooled when leaving the onboard power supply, and the total amount of the refrigerator is relatively large and it is inconvenient to carry. The so-called "universal on-board refrigerator" of the fourth-generation all-round car refrigerator means that it can use domestic 220V AC, and can use 12V DC on-vehicle electricity. It can also continue cooling without power supply, so as to avoid the semiconductor car refrigerator. The shortcomings of being unable to continue cooling after being parked with a compressor, such as a compressor in a car, solves the shortcomings of a passive car refrigerator that cannot leave the refrigerator for a long period of time.

Features 1. It can be applied to all kinds of voltage power supply. Whether it is 12VDC, 24VDC, 110VAC or 240VAC, the built-in power supply unit of compressor car refrigerator can automatically identify different voltages and make corresponding adjustments.
2. The medium-sized compressor car refrigerator has the features of convenient transportation and excellent internal and external dimensions.
3, the compressor car refrigerator is most suitable for off-road vehicles, cars, trucks, buses, as well as yachts and boats. You can also secure them in the car if necessary.
4. Advanced compressors for on-board refrigerators provide superior refrigeration power for our freezers. At the same time, their energy-saving features and mute functions allow us to enjoy the supreme enjoyment from our customers.

The use method does not need to install, directly on the car seat or on the carpet, or placed in the trunk (if the trunk does not have power, we can provide the cigarette lighter power conversion line), can be placed upright horizontally.

The all-round car refrigerator combines the advantages of several types of car refrigerators. It has made breakthrough improvements in terms of power supply selection, cooling temperature, cost performance, and portability, and represents the development direction of car refrigerators.
