Abstract

The invention discloses a welding-free type coaxial pipe. A low-pressure inlet pipe 1 is inserted in one end of a connector 15 and sealed through an O-shaped ring. A low-pressure outlet pipe 13 is inserted in the other end of the connector 15 and sealed through an O-shaped ring. The low-pressure outlet pipe 13 is pressed through a right pressing plate 12 and locked and fixed through a bolt. An inner tooth high-pressure inlet pipe 2 is arranged on the low-pressure inlet pipe 1 in a sleeving manner and inserted in the connector 15. The inner tooth high-pressure inlet pipe 2 and the connector 15 are sealed through an O-shaped ring. The inner tooth high-pressure inlet pipe 2 and the low-pressure inlet pipe 1 are pressed through a left pressing plate 5 and locked and fixed through a bolt. A high-pressure outlet pipe 9 is inserted in the upper end of the connector 15 and sealed through an O-shaped ring 7. The high-pressure outlet pipe 9 is pressed through an upper pressing plate 8 and locked and fixed through a bolt. The welding-free type coaxial pipe has the beneficial effects that rapid assembling can be achieved, a certain universal type is achieved, and welding is not needed.

Description

technical field [0001] The invention belongs to an automobile air conditioner, and in particular relates to the connection mode of the inlet and outlet of coaxial pipes. Background technique [0002] The coaxial tube is part of the air conditioning system in the car cooling module, and its main function is to connect channels and heat exchange. [0003] The coaxial tube is a new technology developed for the purpose of improving heat exchange efficiency and energy saving in the current automobile cooling module; compared with the non-coaxial tube system, the heat exchange capacity of the system can be improved by about 10%; the current coaxial tube inlet and outlet part of the tube Both the pressure plate and the joint of the road are connected and sealed by welding, which requires machine welding and tooling or senior technicians to ensure the welding quality and size, and the welding efficiency is low, the tooling is not universal, and the cost is high.
