Condenser

Abstract

A first header tank (3) to which first heat exchange tubes (2A) of third and fourth heat exchange paths (P3, P4) are connected and a second header tank (4) to which second heat exchange tubes (2B) of first and second heat exchange paths (P1, P2) are connected are provided at one end of a condenser (1). The upper end of the first header tank is located above the lower end of the second header tank. The first header tank has a function of separating gas and liquid and storing the liquid. A spacer (21)is disposed between the first header tank (3) and the second header tank (4). The spacer includes a first portion (22) which comes into contact with and is brazed to the first header tank, and a second portion (23) which comes into contact with and is brazed to the second header tank. The condenser is suitably applied in a vehicle air conditioned mounted on a vehicle.

Description

technical field [0001] The present invention relates to a condenser suitable for use in, for example, an automobile air conditioner mounted on an automobile. Background technique [0002] In this specification and claims, the term "condenser" includes not only a normal condenser but also a subcooled condenser having a condensing part and a subcooling part. [0003] In addition, in this specification and claims, up and down, left and right refer to figure 1 and figure 2 Up and down, left and right. [0004] For example, as a condenser for an automobile air conditioner, there is known a condenser that has a plurality of flat heat exchange tubes extending in the left-right direction with the width direction facing the ventilation direction and arranged in parallel at intervals in the up-down direction; The left and right ends of the heat exchange tubes are connected to the liquid collection tank extending in the vertical direction, and the heat exchange passages composed of...

AI Technical Summary

Problems solved by technology

[0005] In the condenser described in the above publication, in order to effectively separate the gas and liquid in the first liquid collecting tank, it is necessary to make the inner volume of the first liquid collecting tank considerably larger than that of the second liquid collecting tank, so the first set The thickness of the liquid tank is considerably larger than that of the second liquid collecting tank, so there is a problem that a large space is required for arranging the condenser

[0006] In addition, other equipment is usually arranged near the condenser, but according to the condenser described in the above publication, the fir...
