Description

Technical Field

[0001] This utility model belongs to the field of air conditioning accessories, specifically relating to a sealing pressure plate structure for the end diameter of an automotive air conditioning pipe. Background Technology

[0002] Air conditioning pipe pressure plate is an indispensable component of automotive air conditioning systems. One end of the pressure plate is welded to an aluminum pipe, and the other end is connected to the compressor, air conditioning system components, etc. The pressure plate connects the pipes to the compressor and other core air conditioning components, ensuring smooth flow of refrigerant within the air conditioning system, thereby achieving the purpose of cooling the air inside the vehicle.

[0003] In existing refrigeration system loops, heat transfer is mostly achieved through the phase change of the refrigerant. The refrigerant absorbs heat when it vaporizes in the evaporator and releases heat when it condenses in the condenser. During the refrigeration cycle, moisture entering the system from the low-temperature side is in the form of water vapor. This water vapor is compressed along with the refrigerant vapor and enters the condenser, where it condenses into liquid water, which then mixes with the refrigerant liquid as droplets. Clearly, a high water content in the refrigerant directly affects the system's cooling performance. In some cases, the water may even freeze at the compressor due to the low temperature, clogging valves and preventing the refrigeration unit from functioning properly. To address the water content issue in the refrigerant, existing technology uses a sight glass in the refrigeration system loop to monitor the water content. Therefore, how to integrate the sight glass with the pressure plate while achieving a simple overall structure and minimal space occupation is a problem our company needs to solve. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a sealing pressure plate structure for the end diameter of automotive air conditioning pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sealing pressure plate structure for the end diameter of an automotive air conditioning pipe includes a pressure plate body and a connector for connecting a compressor. The pressure plate body is provided with a platform for installing a sealing gasket. The connector is installed on the platform. The connector is provided with a flow channel one, which is connected to a flow channel two provided inside the pressure plate body. One end of the flow channel two is connected to a connection hole provided on one side of the pressure plate body for welding a high-pressure aluminum pipe.

[0007] This utility model further defines the technical solution as follows:

[0008] Preferably, the pressure plate body, platform, and connector are integrally formed.

[0009] Preferably, the first flow channel and the second flow channel are perpendicular to each other.

[0010] Preferably, the pressure plate body is provided with fixing holes.

[0011] Preferably, the outer wall of the connector is provided with a sealing ring groove for installing a sealing ring.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] This utility model connector achieves a double sealing effect after the compressor and high-pressure aluminum pipe are quickly assembled by adding a sealing ring groove to the outer wall of the connector. It effectively utilizes space and improves the risk of high end face sealing leakage. The overall structure is compact, saves materials, and better improves the risk of leakage when the end face sealing connection is made. Attached Figure Description
