Auto Condenser Aftermarket Competition Is Also Very Intense

In China, air conditioning is basically the standard car, so the air conditioning parts (including the condenser, including) aftermarket demand is very large. However, due to the relatively low manufacturing threshold, the condenser of the production plant many, therefore, the domestic automotive condenser aftermarket competition is also very intense.

Car air conditioning needs a condenser, the main role is to cool the cooling. Its position is generally in the forefront of the car, its purpose is to travel in the car when the wind on the face of the air to cool the pipeline.

From the earliest tube structure, to the serpentine structure, to the parallel flow condenser, the process of car condenser and heat transfer efficiency level with the continuous development of automotive technology to continue to improve; the same time, the structure of the condenser Tighten to meet the car lightweight and increasingly stringent environmental requirements.

According to media type

1. Water-cooled

In this type of condenser, the heat released by the refrigerant is taken away by the cooling water. Cooling water can be used once or for recycling. Water-cooled condenser according to its different structural types can be divided into vertical shell and tube, horizontal shell and casing and casing and other.

Air cooling

In such a condenser, the heat released by the refrigerant is taken away by air. Air can be natural convection, can also use the fan for forced flow. This type of condenser is used in frean refrigeration units where water supply is difficult or difficult.

3. Water-air cooling

In such a condenser, the refrigerant is cooled by water and air at the same time, but mainly by the evaporation of the cooling water on the surface of the heat transfer tube, drawing a large amount of heat from the side of the refrigerant as the latent heat of vaporization of water and the action of air Mainly to speed up the evaporation of water and take away the steam. So this type of condenser water consumption is very small, for air drying, water quality, low water temperature and water is not sufficient area is the preferred type of condenser. This type of condenser according to its different types of structure can be divided into two kinds of evaporation and leaching.

4. Evaporation - Condensation

In this type of condenser, the coolant produced by the evaporation of the refrigerant in the other refrigeration system is used to cool the refrigerant vapor on the other side of the heat transfer compartment, causing the latter to condense and liquefy.

According to the characteristics of automotive air-conditioning system commonly used parallel flow (air-cooled) condenser more; parallel flow condenser is characterized by high performance, lightweight; due to the use of high-performance fins and flat tube, making parallel flow condenser is very light The The arrangement of the manifold and the flat tube causes the condensed liquid working fluid to be mixed with the gaseous working fluid in the manifold, thereby greatly improving the heat transfer efficiency.

Pressure loss is small

Parallel flow condenser working fluid circuit was multi-channel parallel arrangement, this arrangement makes the working side of the pressure loss than the tube condenser with more than half, thus greatly reducing the load on the compressor.

Volume is reduced

The internal volume and refrigerant required for the parallel flow condenser are 25% less than the belt condenser, thus reducing costs and reducing the weight. While reducing the amount of working fluid, improve the economy.

High durability

The new material of the flat tube and fins and its anti-corrosion treatment to the condenser from the electrolytic corrosion perforation. Parts of the surface by the chemical film, electrostatic powder spray to make life longer.

At the same time, with the continuous development of technology, in the parallel flow structure, derived from a number of other types of parallel flow condenser structure, such as: integrated tank parallel flow condenser (KOMO); integrated gear oil Parallel flow condenser and so on.

Features

The car condenser cools and liquefies the high-pressure, high-temperature refrigerant (gaseous refrigerant) sent from the compressor. The condenser will release the refrigerant from the heat obtained when the air passes through the evaporator, which will be accomplished by the flow of air as the vehicle moves and the air flow created by the cooling fan.
