The role of condensers is to convert high-temperature, high-pressure gas refrigerants from compressors into liquid refrigerants, which are heat-dissemination in condensers. The condenser is therefore a heat exchanger that distributes the heat absorbed by the refrigerant inside the vehicle through the condenser into the atmosphere。
The condensers of small cars are usually installed in front of the car (usually in front of the radiator) and cooled through the fan (the condenser fan is generally shared with the radiator fan, and the car type uses a specialized condenser fan)。
The structure of the condensers, as shown in the figure, consists mainly of pipelines and radiators, with one refrigerant imported and one export exported。
Automobile condensers:
Refrigerants enter evaporateers, reduce pressure, shift from high-pressure gases to low-pressure gases, a process that absorbs heat, so evaporaters have low surface temperatures and can blow cold winds through fans. The . L condenser is a high-pressure, high-temperature refrigerant from the compressor, cooling into high-pressure, low-temperature ... And then evaporates in the evaporation unit through cachot gasification。

Car condenser classification
Depending on the type of cooling medium, condensers can be grouped into four broad categories with the following effects:
(1) evaporation-cooled:
In such condensers, the cooling of refrigerant vapours on the other side of the heat transfer wall by relying on the cooling effects of the evaporation of refrigerants in another refrigeration system led to condensation. For example, evaporation - condensers - is in a collapsible chiller。
(2) air cooling (also called wind cooling):
In these condensers, the heat released by the refrigerant is removed from the air. Air can be a natural convection or forced flow using wind machines. Such condensers are used in freon refrigeration units in locations where water supply is difficult or difficult。
(3) water cooling:
In these condensers, the heat released by the refrigerant is removed by cooling water. Refrigerated water can be used either once or again. Water cooling condensers can be divided by their different structural configurations into three-hull tubes, one-bed ones and one-sets。
(4) water-air cooling:
In such condensers, refrigerants are cooled by both water and air, but rely mainly on cooling water for evaporation on the surface of the heating tube, extracting large amounts of heat from the side of the refrigerant as a vapour subheating of water, and the role of the air is mainly to remove water vapour to accelerate evaporation. As a result, these condensers consume very little water and are preferred for areas with dry air, water quality, low water temperature and insufficient water. Such condensers can be divided into evaporated and hormonal types according to their structural pattern。
