Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning evaporators, in particular to an automobile air-conditioning evaporator. Background Art

[0002] The automotive air conditioning system is an indispensable part of modern cars, providing a comfortable riding environment for drivers and passengers. The evaporator in the air conditioning system is one of the core components. Its main function is to reduce the temperature and remove moisture by absorbing the heat in the car, thereby cooling and dehumidifying. The working principle of the evaporator is to use low-pressure and low-temperature refrigerant to vaporize inside the evaporator. Through this process, the heat in the air is absorbed to achieve a cooling effect.

[0003] The evaporator is usually composed of aluminum fins and tubes. These fins provide a large area of ​​heat exchange surface, making the heat exchange between air and refrigerant more efficient. However, during the use of the evaporator, the fins inside it are prone to accumulate dust, dirt and other particulate matter. These accumulations will gradually affect the heat exchange efficiency of the fins because they reduce the contact area between the air and the fin surface, thereby affecting the cooling effect of the entire air conditioning system. In addition, dust and dirt may also cause the growth of bacteria and mold, affecting the air quality in the car.

[0004] Due to the narrow spacing between fins and the complex shape design that is usually designed to improve heat exchange efficiency, it is difficult to thoroughly clean the dust and dirt between the fins using traditional cleaning methods. In daily maintenance, although the dust on the surface can be cleaned by blowing or using special cleaning agents, these methods often make it difficult to completely remove the dirt stuck deep in the fins, and the wrong cleaning method may also damage the fins.

[0005] Based on this, those skilled in the art have proposed an automobile air-conditioning evaporator. Utility Model Content

[0006] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide an automobile air-conditioning evaporator.

[0007] The technical solution of the utility model is as follows: an automobile air-conditioning evaporator comprises an evaporator body, wherein a flow guide pipe is fixedly connected to the interior of the evaporator body;

[0009] The heat dissipation mechanism can be movably connected to the evaporator body, and the heat dissipation mechanism is used to realize heat exchange and heat dissipation for the guide pipe.

[0010] Through the above technical means, the guide pipe is used to transport the coolant, and the heat dissipation mechanism is used to exchange heat for the coolant, so that the coolant can be cooled better.

[0011] As a preferred embodiment, the heat dissipation mechanism includes a heat dissipation plate, a connecting column and a position avoidance hole;

[0012] The heat dissipation plates are arranged equidistantly in a vertical structure, the connection columns are fixedly connected between the corresponding heat dissipation plates, and the avoidance holes are equidistantly opened on both sides of the heat dissipation plates.

[0013] Through the above technical means, the heat sink can increase the contact area as much as possible through the avoidance holes, thereby achieving a better cooling effect.

[0014] As a preferred embodiment, the heat dissipation mechanism further includes a liquid leakage hole, a mounting plate, a mounting hole and a plug plate;

[0015] The leakage holes are equidistantly arranged on the heat dissipation plate, one end of each connecting column extends to the outside of the evaporator body and is fixedly connected to the mounting plate, and the mounting holes are equidistantly arranged on the mounting plate.

[0016] Through the above technical means, the entire heat dissipation mechanism can be pulled out from the evaporator body by pulling the mounting plate, thereby facilitating subsequent cleaning, and the heat dissipation mechanism can be fixed on the evaporator body through the mounting hole.

[0017] As a preferred embodiment, through grooves are equidistantly provided on both sides of the evaporator body and located on the outside of the corresponding connecting columns, the plug plates are fixedly connected to the mounting plate and located on the outside of the connecting columns, and the plug plates are used in conjunction with the corresponding through grooves.

[0018] Through the above technical means, by inserting the plug plate into the through groove, the evaporator body can be sealed, so that the water stains formed by evaporation can flow out along the external pipe.

[0019] As a preferred implementation, the guide tube is made of copper, and the heat sink is made of aluminum.

[0020] Through the above technical means, copper and aluminum materials are both high-performance thermal conductive materials, suitable for use in heat exchange.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:
