Benefits of technology

[0005] The present invention is designed to solve the problems as described above, therefore the objective is to decrease the number of assembling processes with regard to the individual parts being constituents of a header pipe, and to minimize or prevent refrigerant leakage at the connecting portions after brazing of individual parts, and to provide a simpler design of a header pipe for an evaporator for use in an automobile.

Problems solved by technology

However, before such brazing process is applied to each part, the assembly of the parts has to be completed and thus the number of assembly processes is increased, which negatively affects productivity and raises costs.
In addition, if there are any incompletely connected parts due to some brazed portions being left uncoated with the clad material after the individual parts were assembled, there is a danger of a decrease in the evaporator's performance due to refrigerant leakage.

Abstract

The present invention relates to a header pipe for a vehicle evaporator capable of decreasing the number of assembling processes of a header pipe and minimizing / preventing a refrigerant leakage at a junction portion after elements are brazed for thereby achieving a simpler construction. In the present invention, a vehicle evaporator is provided with a header pipe, comprising a tank part and a header part forming an integral structure wherein a partition wall partitioning a refrigerant flow path space of the tank part, a partition plate for changing a refrigerant flow path at the tank part, and caps for covering the openings of both sides of the tank part are assembled in a structure.

Description

FIELD OF THE INVENTION [0001] The present invention applies to the technology of an evaporator being a constituent of an air conditioning system for use in an automobile, and more precisely—to a header pipe used at the connection point with the end portion of a tube through which the refrigerant flows in an evaporator. BACKGROUND OF THE INVENTION [0002] The present invention applies to the technology of an evaporator being a constituent of an air conditioning system for use in an automobile, and more precisely—to a header pipe used at the connection point with the end portion(s) of a tube(s) through which the refrigerant flows in an evaporator. [0003] An evaporator, being a commonly used constituent of an air conditioning system for use in an automobile, wherein numerous tubes through which the refrigerant flows, and heat transfer fins form its core, and each tube's end part connects through the header pipe into a structure. [0004] The attached FIG. 1 illustrates an example of the a...
