Condenser

Abstract

The condenser (1) has a set of heat exchange pipes (2A, 2B) arranged parallel to each other. Left and right end sections of the pipes are connected with collection tanks (3-5). A group comprises four heat exchanging paths (P1-P4), where three of the paths are designed as coolant condensation paths, and the remaining path is designed as a coolant undercooling path. One of the tanks comprises a branch control device that conveys flux from a coolant in a fluid state of the tank into one of the pipes for forming the coolant undercooling path.

Description

technical field [0001] The present invention relates to a condenser suitable for use in, for example, a refrigerating cycle mounted on an automobile, that is, an automobile air conditioner. Background technique [0002] In this specification and claims, up and down, left and right refer to figure 1 Up and down, left and right. [0003] For example, as a condenser for an automobile air conditioner, there is known a condenser having a plurality of heat exchange tubes arranged in parallel at intervals in the vertical direction, and a tube extending in the vertical direction connected to the left and right ends of the heat exchange tubes. There are three heat exchange passages composed of a plurality of heat exchange tubes arranged in parallel up and down, and the refrigerant flow direction of all the heat exchange tubes constituting each heat exchange passage is the same and adjacent to each other. The refrigerant flow directions of the heat exchange tubes of the two heat exc...

AI Technical Summary

Problems solved by technology

[0004] 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

[0005] In addition, other equipment is usually arranged near the condenser, but according to the condenser described in the above publication, the first liquid collection tank becomes an obstacle to other equipment.

For example, a radiator is usually arranged on the downstream side of the ventilation direction of the condenser for automobile air conditioners, but according to the condenser described in the publication, the first liquid collecting tank will become an obstacle to the installation of the radiator, and wasteful waste will be generated in the engine room. space, no space savings

In addition, since the heat exchange tube is connected to the first liquid collecting tank substantially in the entire length, there is a problem that the gas-liquid separation performance is insufficient.
