Problems solved by technology

[0005] That is, it is impossible to secure a working space for joining the blocking member
[0006] In addition, the case of the heat exchanger may be deformed by the heat of the obturating members when they are engaged
[0007] In addition, due to the large thermal mass of the reservoir, it is not possible to heat up the obturator member as desired, so bonding takes time

Abstract

A heat exchanger (1) includes: a pair of tanks (2, 3) arranged at a predetermined interval; a plurality of tubes (4a) having both end portions communicably connected to the pair of tanks (2, 3); a prolonged liquid container (5) which is arranged adjacent to the tank (3) and communicably connected to the tank (3); a containing member (20) contained in the liquid container (5); an upper opening end portion (13b) having an opening of a reduced diameter at one side in the longitudinal direction of the liquid container (5); and a closing member (15) which closes the upper opening end portion (13b). The entire heat exchanger (1) excluding the containing member (20) and the closing member (15) is integrally formed by a soldering process. After the soldering process, the containing member (20) is inserted from the upper opening end portion (13b) into the liquid container (5). After the insertion and arrangement of the containing member (20), the closing member (15) is bonded to the upper opening end portion (13b) by a soldering process.

Description

technical field [0001] The present invention relates to heat exchangers and methods for their manufacture. Background technique [0002] As a conventional heat exchanger, there is known a structure in which a desiccant is inserted into a reservoir and the inside of the reservoir is sealed with a closing member (see Patent Document 1). [0003] Patent Document 1: Japanese Patent Application Laid-Open: No. 8-110125 [0004] However, in conventional heat exchangers, when improving the pressure resistance of the accumulator, the closing member is joined to the opening end of the accumulator by, for example, welding. At this time, since the liquid receiver is very close to the tank of the heat exchanger, the problems listed below arise. [0005] That is, a working space for joining the blocking member cannot be ensured. [0006] In addition, the tank of the heat exchanger may be deformed by the heat of the obturating members when they are joined. [0007] In addition, since t...
