Description

Technical Field

[0001] The utility model relates to the field of condensers, in particular to a high-efficiency heat dissipation condenser. Background Art

[0002] The working principle of the car condenser is to reduce the temperature of the refrigerant by dissipating heat, so that the surface temperature of the evaporator is lowered, and then the cool air is blown out by the fan. Specifically, after the refrigerant enters the evaporator, the pressure decreases, and it changes from high-pressure gas to low-pressure gas. In this process, it absorbs heat, which reduces the surface temperature of the evaporator. The car condenser cools the high-pressure, high-temperature gaseous refrigerant from the compressor into high-pressure, low-temperature liquid refrigerant, thereby reducing the temperature inside the car. In the air conditioning system, the condenser is usually located at the front of the car, close to the radiator, so as to use the air flow when the vehicle is driving to assist in heat dissipation. There are many small pipes and cooling fins inside the condenser. When the high-temperature and high-pressure gaseous refrigerant passes through these pipes, it exchanges heat with the outside air. Due to the air flow generated by the vehicle when it is driving, or with the help of the fan, the condenser can effectively dissipate the heat of the refrigerant to the outside air.

[0003] The number of cooling fins on the automobile condenser is huge and they are solid, which directly increases the weight of the condenser and indirectly increases the fuel consumption of the vehicle. At the same time, when the air circulates on a single fin, a relatively stable air layer is formed, which reduces the residence time of the gas on the cooling fin, thereby reducing the heat dissipation effect of the condenser.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model arranges the flow holes on the multi-layer heat sink relative to each other, so that the airflow impacts the multi-layer heat sink, which can increase the contact area between the multi-layer heat sink and the air, thereby improving the heat dissipation efficiency. The arrangement of the flow holes can promote the flow of air between the fins, breaking up the air layer that may have been relatively stable, so that the hot air is replaced by the cold air more quickly. When the air flows through the flow holes, it will form local turbulence, which can effectively remove heat from the fin surface, thereby improving the heat dissipation effect.

[0014] 2. By opening multiple groups of flow holes on the heat sink, the utility model can remove some materials, thereby reducing the weight of the entire heat dissipation structure without significantly affecting the heat dissipation performance, indirectly reducing the weight of the vehicle body and reducing fuel consumption;

[0015] 3. The utility model arranges wind blocks on the outside of a large number of heat sinks. The arrangement of the wind blocks can block the airflow on the surface of the heat sink, prolong the residence time of the airflow on the surface of the heat sink, and turbulent the airflow on the surface of the heat sink, thereby improving the heat dissipation efficiency of the heat sink and increasing the heat dissipation effect of the automobile condenser.
