Header pipe evaporator for use in an automobile

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.

1 . A header pipe assembly for a vehicle heat exchanger, the header pipe comprising: 
 a tank part and a header part forming an integral structure, the tank part having a refrigerant flow path space;    a partition wall partitioning the refrigerant flow path space of the tank part;    a partition plate for changing a refrigerant flow path in the tank part; and    a pair of caps closing respective openings at each end of the tank part.    
   
   
       2 . The header pipe assembly of  claim 1 , wherein a rounding portion is formed between the tank part and the header part in the integral structure.  
   
   
       3 . The header pipe assembly of  claim 1 , wherein said partition wail, said partition plate and said cap are braze-coupled with the integral structure of the tank part and the header part using braze paste.  
   
   
       4 . The header pipe assembly of  claim 1 , wherein a rail groove for slide-inserting the partition wall therein is formed at the tank part and the header part, respectively, and an insertion groove for receiving the partition plate therein is formed at the tank part.  
   
   
       5 . The header pipe assembly of  claim 1 , wherein the partition wall, the partition plate and the cap are braze-coupled with the integral structure of the tank part and the header part using a clad material.
