A car refrigerator is a refrigeration device used inside a car to store food, beverages and other items. Its core component is the refrigeration system, which is responsible for realizing the refrigeration and freezing functions. According to different working principles and refrigeration methods, the refrigeration system of a car refrigerator can be divided into many types.
The compression refrigeration system is one of the most common types of refrigeration systems for car refrigerators. This system achieves refrigeration by compressing the refrigerant, and has the advantages of fast refrigeration speed and high refrigeration efficiency. It is usually composed of a compressor, a condenser, an evaporator and an expansion valve. The refrigerant is compressed into a high-pressure gas during the working process, and becomes a high-pressure liquid after dissipating heat through the condenser, and then evaporates into a low-pressure steam through the expansion valve to absorb heat and reduce the temperature, and finally achieve the refrigeration effect.
Thermoelectric refrigeration system is another common type of refrigeration system for car refrigerators. This system achieves refrigeration through the thermoelectric effect, and has the advantages of small size, low noise and strong portability. It is usually composed of a thermoelectric module, a heat sink, a cooling fin and a power controller. The thermoelectric module generates a hot and cold side effect when an electric current passes through it, causing one side to cool down and the other side to heat up, thereby achieving a refrigeration effect. Suitable for small car refrigerators, such as car refrigerators.
The adsorption refrigeration system is a relatively new type of refrigeration system, which is gradually being used in the field of car refrigerators. The refrigeration effect is achieved by adsorbing and desorbing the refrigerant by the adsorbent, which has the advantages of no noise, high efficiency, and environmental protection. It is usually composed of an adsorber, a desorber, a condenser, and an evaporator. The adsorbent releases heat when adsorbing the refrigerant and absorbs heat when desorbing to achieve the refrigeration effect. It is suitable for car refrigerators that require low noise, high efficiency, and environmental protection.
The heat pipe refrigeration system is an emerging type of refrigeration system with the advantages of high efficiency, energy saving, and environmental protection. The refrigeration effect is achieved through the heat transfer principle of the heat pipe, without mechanical compression, and has the advantages of no noise, high efficiency, and high reliability. It is usually composed of a heat pipe, an evaporator, a condenser, and an expansion valve. The working fluid in the heat pipe absorbs heat and evaporates in the evaporator, and then releases heat and condenses in the condenser to achieve the refrigeration effect. It is suitable for car refrigerators with high requirements for refrigeration efficiency and environmental protection.
