Description

Technical Field

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

[0002] The porous plate of the automobile air-conditioning evaporator plays a vital role in the automobile air-conditioning system. With the continuous development of the automobile industry and people's increasing demand for a comfortable driving environment, the performance requirements for automobile air-conditioning are also getting higher and higher. In order to improve the cooling effect of automobile air-conditioning, improve the speed and uniformity of temperature adjustment in the car, and reduce energy consumption, optimizing the design of the evaporator porous plate has become an important research direction.

[0003] Among the current existing market products, most porous plates have a flat surface. This design has certain limitations. When the pressure inside the system is insufficient, the refrigerant cannot flow quickly when passing through the porous plate, which leads to poor cooling effect of the air-conditioning system. The refrigerant cannot circulate smoothly in the system, and thus cannot quickly and effectively take away the heat. The cooling time inside the car space is too long, and passengers need to wait for a long time in the car to feel a comfortable temperature, which greatly affects the user experience and satisfaction. Utility Model Content

[0004] The utility model aims to solve the problem that the existing porous plate cannot make the refrigerant flow quickly, resulting in insufficient refrigeration of the air-conditioning system and a long cooling time inside the automobile space. The utility model provides a porous plate for an automobile air-conditioning evaporator.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A porous plate of an automobile air-conditioning evaporator comprises a plate body, a plate side body is arranged on the front side of the plate body, a concave-convex strip is arranged in the middle of the side wall of the plate side body, the connecting part between the plate side body and the concave-convex strip is a curved arc, the inside of the concave-convex strip is located inside the plate body, the upper and lower end edges of the plate side body are arranged with connecting areas, the connecting area is arranged with concave-convex points, the concave-convex points are located outside the connecting area and are evenly distributed in the connecting area, the concave-convex strip and the concave-convex points are convex to the outer plane of the plate side body, and the side wall of the plate body is arranged with holes at both side ends of the plate side body.

[0007] Furthermore, the plate body is in the shape of a long strip, and the plate side body, the concave-convex strips, the connecting area and the concave-convex points together constitute the concave-convex surface of the plate body. The concave-convex surface is designed on the side of the plate body, and the water flow through the convex points will be accelerated, thereby accelerating the flow of refrigerant inside the air-conditioning system, thereby shortening the cooling time of the interior space of the car.

[0008] Furthermore, the concave and convex points are arranged in plurality at the connection area and are parallel to each other, and the edge of each of the concave and convex points is arranged in a serrated shape, which can be used to clamp, fix or guide other components.

[0009] Furthermore, the concave-convex points are located on the outside of the connecting area, and after deformation, the concave-convex points are located inside the connecting area and recessed. After deformation again, the concave-convex points are recessed inside the connecting area, and the flow of refrigerant inside the air-conditioning system can be accelerated by the phenomenon that water flow will be accelerated when passing through the convex points.

[0010] Furthermore, the connection angle between the connection area and the plate side body is an obtuse angle that bends inward, and after deformation, the connection angle between the connection area and the plate side body is an obtuse angle that bulges outward, and after deformation again, the connection angle between the connection area and the plate side body is close to a right angle that is concave inward, and one side of the plate side body cooperates with the collecting pipe to form a water chamber, and they together constitute a channel for the refrigerant inside the evaporator.

[0011] Furthermore, the convex and concave strips are located at the side walls of the plate side bodies and protrude outward. After deformation, the convex and concave strips are concave on the inner side of the plate side bodies. After deformation again, the convex and concave strips are convex on the surface of the plate side bodies. The flow of water passing through the convex points can be accelerated, thereby accelerating the flow of refrigerant inside the air-conditioning system.

[0012] Compared with the prior art, the utility model provides a porous plate for an automobile air-conditioning evaporator, which has the following beneficial effects:

[0013] The porous plate of the automobile air-conditioning evaporator has a concave-convex surface designed on its side. When water flows through the convex points, it will flow faster, thereby accelerating the flow of refrigerant inside the air-conditioning system. The holes set allow the refrigerant to be evenly distributed and flow. The porous plate and the collecting pipe cooperate to form a water chamber, which is the channel for the refrigerant inside the evaporator. Compared with the conventional structure, this side design of concave-convex surface can significantly accelerate the flow of refrigerant inside the air-conditioning system through the phenomenon that water flows faster when passing through the convex points, thereby shortening the cooling time of the interior space of the car and improving the comfort of the interior space.

The concave-convex surface is designed on the side of the plate body 1. The flow of water through the convex points will be accelerated, thereby accelerating the flow of refrigerant inside the air-conditioning system, thereby shortening the cooling time of the interior space of the car. A plurality of concave-convex points 5 are arranged at the connecting area 4 and are parallel to each other. The edge of each concave-convex point 5 is arranged in a serrated shape, which can be used to clamp, fix or guide other components.

[0025] Embodiment 2:

[0026] like Figure 1-Figure 6As shown, the concave-convex point 5 is located on the outside of the connecting area 4, and the position of the concave-convex point 5 after deformation is located inside the connecting area 4 and is recessed, and after deformation again, the concave-convex point 5 is recessed on the inner side of the connecting area 4, and the flow rate of the refrigerant inside the air-conditioning system can be accelerated by the phenomenon that water flows through the convex points. The connecting angle between the connecting area 4 and the plate side body 2 is an obtuse angle bent inward, and the connecting angle between the connecting area 4 and the plate side body 2 is an obtuse angle convex outward after deformation again. The connecting angle between the connecting area 4 and the plate side body 2 is close to a right angle concave inward, and one side of the plate side body 2 cooperates with the collecting pipe to form a water chamber, which together constitute a channel for the refrigerant inside the evaporator, and the concave-convex strip 3 is located at the side wall of the plate side body 2 and protrudes outward.

The small holes of the porous plate allow the refrigerant to be evenly distributed and flow, while the manifold is responsible for collecting and distributing the refrigerant. Such a design can ensure that the refrigerant is fully utilized inside the evaporator, improve the refrigeration efficiency, and also help reduce the pressure loss and energy loss of the refrigerant during the flow process.
