Connection structure of inlet and outlet pipeline and pipe base of parallel flow type evaporator

Abstract

The invention relates to a connection structure of an inlet and outlet pipeline and a pipe base of a parallel flow type evaporator. The connection structure comprises a lateral plate and an end plate. A plurality of first holding claws for tightly holding the outer wall of the pipe base are arranged on the lateral plate. The connection structure is characterized by further comprising a pipe connection gasket which is fixedly riveted with the joint end of a liquid inlet pipe and a gas outlet pipe; the lateral plate is an integrally punched structure; a plurality of second holding claws reverseto the first holding claws are arranged on the lateral plate; the lateral plate is used for tightly holding the pipe connection gasket on the outer end face through the second holding claws; the riveted part among the pipe connection gasket, the liquid inlet pipe and the gas outlet pipe is just aligned with the port of an upper pipe base; and third holding claws for tightly holding the lateral plate and the pipe connection gasket are arranged at two sides of the end plate. By adopting the structure, the liquid inlet pipe and the gas outlet pipe are ensured to be fixedly arranged on the port of the upper pipe base before entering a brazing furnace; the one-time welding and forming process of the evaporator is realized; and, compared with the prior art, the manual welding process is saved, the production period of a product is shortened, the production quality and the production efficiency are increased, simultaneously, the manufacture cost of the product is reduced.

Description

technical field [0001] The invention relates to a parallel-flow evaporator structure for an automobile air conditioner, in particular to a connection structure between an inlet and outlet pipeline of the evaporator and a pipe seat. Background technique [0002] The parallel flow evaporator is a heat exchange device in the automotive air-conditioning system. It is composed of a core assembly, an upper pipe seat assembly, a lower pipe seat assembly, and a liquid inlet pipe and an air outlet pipe welded to the port of the upper pipe seat. The refrigerant passes through The liquid inlet pipe enters the inside of the core body, and exchanges heat with the outside air during the process of flowing in the core body, cooling the air in the car, and the refrigerant is vaporized after absorbing heat, and is discharged through the air outlet pipe. At present, the molding method of the above-mentioned parallel flow evaporator is as follows: first, the core body assembly, the upper tube...

AI Technical Summary

Problems solved by technology

The above-mentioned parallel flow evaporator needs to go through two welding processes of brazing and manual welding, the production cycle of the product is long, and the output is low. In addition, in order to ensure the quality of manual welding, the technical level of welding personnel is high, which leads to an increase in the production cost of the product
