In the hot summer, as soon as you leave the air conditioner, it seems to be heated, and it is best to be surrounded by air conditioning 24 hours a day. Fortunately, modern technology has developed, and air conditioning can be blown not only in the room, but also in the car. Have always been curious, installed in the room air conditioning volume is so big, then the car air conditioning? It was later learned that it was mainly by condensers. Today we will take a look at the condenser in the car.
1. Structure and advantages of parallel flow condenser
The condenser is the main heat exchange component in the air conditioning. The heat absorbed by the air conditioning system and the heat generated by the work of the compressor all rely on it to distribute to the outside air. So far, the condenser has been developed to the third generation. The first generation is tube type, its structure is copper tube through aluminum fin; The second generation is pipe belt type, which is to bend the extruded aluminum flat tube into a snake, and then weld the strip aluminum fin in the middle. Because the copper is eliminated and the aluminum structure is adopted, and the channel structure of the refrigerant is optimized, the heat dissipation efficiency is improved, so the weight is greatly reduced; The third generation is the parallel flow structure.
Parallel flow condenser is a major improvement on the basis of pipe belt type, which further reduces the hydraulic radius of aluminum flat tube, strengthens the heat transfer on the refrigerant side, and is equipped with collecting tubes on both sides of the condenser. The refrigerant channel is designed according to the law of the shrinking volume of refrigerant from gas to liquid state, so as to further improve the heat dissipation efficiency. In this way, the condenser can be designed very thin, the wind resistance is greatly reduced, and the weight is also reduced. The technical level of parallel flow condenser can be said to have reached a quite high level, and it is difficult to have a major breakthrough in the overall structure. The improvement focus is only on how to better distribute the channel of refrigerant.
2. Structure and advantages of tubular condenser
A tubular condenser is a device used to cool air. The tubular condenser is composed of a shell, a tube bundle and a heat sink, etc. Its interior is a water chamber and a steam chamber, and the two chambers are connected by pipes. Advantages of tubular condenser
(1) Simple structure and small volume; (2) High thermal efficiency; (3) Light weight and easy to manufacture; (4) Safe and convenient to use; (5) Long service life
(2) The diameter of the tube is generally less than 1m called capillary tube, greater than 1m called coarse tube. Under the same conditions, the heat conductivity of the thick tube is much lower than that of the thin tube.
Therefore, for the same type of refrigerator: when the evaporation temperature of the coarse tube is lower than that of the fine tube, it is better to choose the coarse tube; When the evaporation temperature of the thin tube is higher than that of the thick tube, the thin tube is better.
Due to the high thermal conductivity of water, the convective heat transfer effect of water is better than that of air.
3. Structure and advantages of chip condenser
The chip condenser is made of high quality stainless steel, its structure is compact, beautiful, easy to install, safe and convenient to operate, because of the high heat exchange efficiency of the condenser, so can greatly reduce energy consumption; And because of its small size, light weight, easy to move and transport. In addition, it can increase the operating temperature and prolong the service life of the equipment.
1. High efficiency and energy saving;
Under the same pressure loss, the heat dissipation effect is 30% higher than that of air-cooled type, and 40% better than that of hot air circulation. It can be widely used in various industrial production processes, such as petroleum processing industry, chemical process and so on. At the same time, it can also be used as one of the means of pre-cooling other cooling devices.
For some occasions with low requirements, it can replace air - cooled radiator.
2. Save space;
Compared with the traditional shell and tube radiator, the heat dissipation area of the chip and tube type is much larger, which saves the valuable room area and is conducive to the aesthetics of the building.
And because of its compact size, it makes the installation more convenient, simple and fast; At the same time, due to its unique structure, it can be installed anywhere needed without occupying additional space such as cabinets or pipes.
3. Reliable operation;
The fully enclosed aluminum fin tube plate makes the water flow unobstructed and not easy to scale and block, thus ensuring the stable operation and long service life of the equipment.
