Heat exchanger
First Claim
1. A heat exchanger which has tubes for flowing a medium and a tank comprising an end plate having tube insertion holes for connecting the tubes and a tank plate connected to the end plate, and is formed by assembling the respective members and brazing the members for connection in a heating furnace;
- wherein;
the tank plate is formed of a plate provided with a brazing material, and at least one of the tank plate and the end plate is provided with a separator portion not having a brazing material for prevention of the brazing material from outflowing.

Abstract
A heat exchanger having tubes 21 for flowing a medium and tanks 3 each formed of an end plate 32 having tube insertion holes 5 for connection of the tubes and a tank plate 31 connected to the end plate, which are assembled and brazed in a heating furnace, wherein the tank plate 31 is formed of a plate provided with brazing materials R1, R2, and at least one of the tank plate 31 and the end plate 32 is provided with separator portions 311, 321 not provided with the brazing material for prevention of the brazing material from outflowing. The tank 3 has partition plates 7 for dividing the interior, the inner surface of at least one of the tank plate 31 and the end plate 32 is clad with the brazing material, and the partition plates 7 are formed of a bare material not clad with a brazing material.
And, the end plate 32 has the brazing material clad on its one surface only, and the ends of the fins 4 and the surface of the end plate 32 not clad with the brazing material are opposed to each other at the time of brazing.
