Abstract

The present invention relates to a piping system. A piping system according to one embodiment of the present invention comprises: at least one pipe through which fluid flows; a fixed block having at least one first through hole formed therein through which fluid flowing in or out through each of at least one pipe flows, at least one coupling groove formed on one side into which one end of each of at least one pipe is inserted and coupled, and at least one connecting pipe formed on the other side that communicates with each of the at least one coupling groove and protrudes outwardly; a fixed plate formed on one side of the fixed block to fix one end of each of at least one pipe while one end of each of at least one pipe is inserted into each of the at least one coupling groove, and a fixed member for fastening the fixed plate to the fixed block, wherein each of the at least one pipe is formed protruding along the outer surface of one end coupled to each of the at least one coupling groove, and a protruding coupling portion is formed that is closely supported by the fixed plate on one side of the fixed block or each of the at least one coupling groove.

Description

Piping system The present invention relates to a piping system, and more specifically, to a piping system that solves the problems that may occur when joining pipes by welding or brazing in conventional piping systems, and can easily and stably fix pipes with a simpler structure. Generally, vehicles include piping systems for transporting various fluids, such as coolant, engine lubricant, refrigerant, and transmission fluid. For example, a vehicle air conditioning system is a system that maintains a comfortable interior environment by regulating the temperature and humidity inside the vehicle through the compression, condensation, expansion, and evaporation of refrigerant, and consists of a compressor, a condenser, an expansion valve, an evaporator, and a refrigerant piping system connecting them. Such a piping system may include a plurality of pipes and a pipe block connected to the plurality of pipes. The pipe block connects the plurality of pipes, allows fluid to flow in and out through the plurality of pipes, and can fix and support each pipe. Conventional piping systems have used joining methods such as soldering or brazing when joining multiple pipes to a pipe block. For example, Korean Registered Patent Publication No. 10-2702884 (Air conditioner piping system and method for manufacturing the same) (published September 5, 2024) discloses a technology for connecting refrigerant pipes and flanges constituting an air conditioner piping system using a brazing method, soldering method, etc. However, conventional piping systems had problems such as requiring a long process time when joining pipes and pipe blocks by welding or brazing, being prone to defects caused by factors like worker error, poor cleanliness of the work surface, and the ingress of impurities during the joining process, and resulting in breakage or leakage at the pipe joints. Therefore, there is a need for a piping system that can solve the problems that may occur when joining pipes by welding or brazing in conventional piping systems, and can easily and stably fix pipes with a simpler structure.
