Description

Technical Field

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

[0002] The manifold of the automobile air-conditioning evaporator is one of the most important core components of the evaporator and plays an indispensable role in the entire air-conditioning system. Its main function is to accurately collect and reasonably distribute the refrigerant so that the refrigerant can flow in an orderly manner inside the evaporator. This process is not only crucial to the normal operation of the automobile air-conditioning system, but also directly related to the comfort of the in-vehicle environment and the quality of the cooling effect.

[0003] The role of ordinary tubes in automobile air-conditioning evaporators is often relatively simple, and they can only allow the refrigerant to pass through more smoothly. This ordinary tube structure is relatively simple and cannot produce the effect of accelerating the circulation of refrigerant. When the refrigerant flows in this ordinary tube, the speed is relatively slow, and it cannot give full play to its potential energy and efficiency, and it is difficult to meet the needs of modern automobile air-conditioning systems for efficient refrigeration and rapid cooling. Utility Model Content

[0004] The utility model aims to solve the problem that the common header pipe type can only allow the refrigerant to pass smoothly but cannot produce the effect of accelerating the circulation. The utility model provides a header pipe 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 collecting pipe of an automobile air-conditioning evaporator comprises a pipe body, a pipe side body is arranged on the front side of the pipe body, a connection area is arranged at the upper and lower end edges of the pipe side body, and concave and convex points are arranged at the connection area. The concave and convex points are located on the inner side of the pipe side body and are evenly distributed at the connection area. A concave and convex strip is arranged in the middle of the side wall of the pipe side body, and the connection point between the concave and convex strip and the pipe side body is a curved arc surface.

[0007] Furthermore, the shape of the tube body is rectangular, and the tube side body, the connecting area, the concave-convex points and the concave-convex strips constitute the concave-convex surface of the tube body. The concave-convex surface is designed on the side of the tube body, and the water flow through the convex points will accelerate the flow, 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 provided in plurality and are parallel to each other, and the edge of each concave and convex point is in a sawtooth shape, which is used for clamping, fixing or guiding other components.

[0009] Furthermore, the parts of the tube side bodies of the plurality of tube bodies are combined together to form a single outlet, which can collect and distribute the refrigerant inside the evaporator, ensuring that the refrigerant flows evenly inside the evaporator, thereby achieving efficient heat exchange.

[0010] Furthermore, the side wall of the concave-convex strip is located on the outside of the tube side body, and after deformation, the side wall of the concave-convex strip is located inside the tube body. The flow of water passing through the convex points can be accelerated, thereby accelerating the flow of refrigerant inside the air-conditioning system.

[0011] Furthermore, the concave and convex points are located outside the plane of the connection area, and are located inside the tube body after deformation. 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 collector for an automobile air-conditioning evaporator, which has the following beneficial effects:

[0013] The manifold of the automobile air-conditioning evaporator has a concave and convex surface carefully designed on the side of the manifold, which cleverly utilizes the physical phenomenon that water flows faster when passing through convex points, thereby significantly accelerating the flow of refrigerant inside the air-conditioning system. This acceleration effect greatly shortens the cooling time of the interior space of the automobile and improves the working efficiency of the air-conditioning system. Compared with conventional structures, it ensures that the refrigerant can flow evenly inside the evaporator, ensures that the evaporator can give full play to its efficient heat exchange function, and achieves the goal of quickly reducing the temperature inside the automobile.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] like Figure 1-Figure 4 As shown, a collecting pipe of an automobile air-conditioning evaporator comprises a pipe body 1, a pipe side body 2 is arranged on the front side of the pipe body 1, a connection area 3 is arranged at the upper and lower edge parts of the pipe side body 2, a concave-convex point 4 is arranged at the connection area 3, the concave-convex point 4 is located on the inner side of the pipe side body 2 and is evenly distributed at the connection area 3, a concave-convex strip 5 is arranged at the middle part of the side wall of the pipe side body 2, and the connection point of the concave-convex strip 5 and the pipe side body 2 is a curved arc surface.

[0022] like Figure 1 and Figure 3 As shown, the shape of the tube body 1 is rectangular, and the tube side body 2, the connecting area 3, the concave-convex points 4 and the concave-convex strips 5 constitute the concave-convex surface of the tube body 1. The concave-convex surface is designed on the side of the tube body 1. The water flow through the convex points will accelerate the flow, thereby accelerating the flow of refrigerant inside the air-conditioning system, thereby shortening the cooling time of the interior space of the car. The concave-convex points 4 are provided in plurality and are parallel to each other. The edge of each concave-convex point 4 is in a sawtooth shape, which is used to clamp, fix or guide other components. The parts of the tube side bodies 2 of the plurality of tube bodies 1 are combined together to form a single outlet. Inside the evaporator, the refrigerant can be collected and distributed to ensure that the refrigerant flows evenly inside the evaporator, thereby achieving efficient heat exchange.

[0023] Embodiment 2:

[0024] like Figure 2 and Figure 4 As shown, the side wall of the concave-convex strip 5 is located on the outside of the tube side body 2, and is located inside the tube body 1 after deformation. The flow of refrigerant inside the air-conditioning system can be accelerated by the phenomenon that water flows through the convex points. The concave-convex points 4 are located outside the plane of the connecting area 3, and are located inside the tube body 1 after deformation. The flow of refrigerant inside the air-conditioning system can be accelerated by the phenomenon that water flows through the convex points.

[0025] Working principle: Figure 1-Figure 4As shown, each concave and convex point 4 is parallel to each other and has a sawtooth-like edge. This design is used to clamp, fix or guide other components. The concave and convex points 4 on the tube body 1 are evenly distributed, and there is a certain distance between each concave and convex point 4, which can provide additional gripping force or friction. These concave and convex points 4 can also help guide or limit the movement of objects, or in some cases, they can be used as connection points for installing other components.

[0026] The tube body 1 is a multi-duct structure, and the parts of the tube side bodies 2 of multiple tube bodies 1 are combined together to form a single outlet. Inside the evaporator, the refrigerant can be collected and distributed to ensure that the refrigerant flows evenly inside the evaporator, thereby achieving efficient heat exchange. The tube body 1 includes an overall structure and a porous plate that cooperates to form a water chamber, which together constitute the channel for the refrigerant inside the evaporator. 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 refrigerants. 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.
