Background

The condenser is a part of a refrigeration system, belonging to a type of heat exchanger, capable of converting a gas or vapor into a liquid, and transferring the heat in the tube to the air in the vicinity of the tube in a rapid manner. Evaporation is the physical process of converting a liquid state into a gaseous state. In general, a vaporizer, i.e. a body in which a liquid substance is converted into a gas state. The evaporator is an important part in four refrigeration parts, and low-temperature condensed liquid passes through the evaporator to exchange heat with outside air, gasify and absorb heat, so that the refrigeration effect is achieved. The evaporator mainly comprises a heating chamber and an evaporating chamber. The heating chamber provides heat required for evaporation to the liquid, causing the liquid to boil and evaporate; the evaporating chamber makes the gas-liquid phase completely separate. However, since the conventional vehicle-mounted refrigerating apparatus has a limited installation position of the evaporator, it is difficult to install a large number of evaporation tubes in a small space, and it is important to obtain an evaporator of the vehicle-mounted refrigerating apparatus that overcomes the above-mentioned drawbacks.
