Problems solved by technology

Therefore, the volume of the liquid storage tank is reduced, which in turn leads to a narrowing of the stable range of the refrigerant recooling state, excessive refrigerant or insufficient refrigerant
Therefore, it is difficult to obtain stable cooling performance
[0015] In addition, since the reservoir 130 is fastened to the block flange 140 with screws, a cumbersome screw tightening operation is required, resulting in cumbersome / difficult assembly operations

Abstract

A heat exchanger with a receiver tank is provided with a multi-flow type heat-exchange body (10), a receiver tank (3), a block flange (4) having a side surface connected to the periphery of a condensing portion outlet of the heat exchanger body (10) and an upper end to which a lower end of the receiver tank (3) is attached and a bracket (6) for supporting the upper part of the receiver tank (3) to the heat exchanger body (10). A flange-shaped pressing stepped portion (31a) is formed on the upper periphery of the tank main body (31) of the receiver tank (3). The bracket (6) is provided with a joint portion (61b) to be secured to the peripheral surface of one of headers (11) and embracing portions (61a) and (62a) that surround the periphery of the tank main body (31) and are engaged with the upper side of the pressing stepped portion (31a) to downwardly press the receiver tank (3). With this heat exchanger, stable refrigeration performance can be obtained and that the assembling operation can be performed easily.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under Section 111(b) of the United States Patent Act to Provisional Application Nos. 60 / 302646, 60 / 302657, 60 / 302690, and 60 / 302708, each filed on July 5, 2001. technical field [0003] The invention relates to a heat exchanger with a liquid storage tank suitable for automobile air-conditioning equipment, and also relates to a refrigeration system using the heat exchanger. Background technique [0004] In recent years, in a refrigerant condensation process used in a refrigeration cycle of an automobile air-conditioning system and the like, the following techniques have been proposed. In this technique, after the recooled refrigerant is obtained by increasing the heat release of the refrigerant by subcooling the condensed refrigerant to drop the temperature to several degrees below its condensing temperature, the recooled refrigerant is introduced into the Compression device and evapora...
