Problems solved by technology

[0005] However, in the condenser described in Patent Document 1, when the refrigerant is sealed into the refrigeration cycle using the condenser, there is a problem that there is a problem in that the amount of refrigerant to be filled is an appropriate amount to keep the degree of subcooling constant. It takes a long time, and the range of the stable area where the supercooling degree remains constant will become narrower

Abstract

A condenser includes a condensation section, a super-cooling section located above the condensation section, and a liquid receiver. The liquid receiver has a first space communicating with the condensation section through a refrigerant inlet and a second space located above the first space and communicating with the super-cooling section through a refrigerant outlet. A partition member is providedin the liquid receiver in order to divide the internal space of the liquid receive into the first space and the second space. A suction pipe which is open at upper and lower ends thereof and which establishes communication between the first space and the second space is disposed in the first space of the liquid receiver. The partition member has an internal volume adjustment portion for increasing the internal volume of the first space and decreasing the internal volume of the second space.

Description

technical field [0001] The present invention relates to, for example, a condenser used in a refrigeration cycle constituting an on-vehicle air conditioner. [0002] In this specification and claims, the figure 1 and figure 2 Up and down, left and right of set to up and down, left and right. Background technique [0003] As a condenser constituting a refrigeration cycle of a vehicle air conditioner, there is known a condenser which has a condenser, a subcooler provided above the condenser, and a liquid receiver provided between the condenser and the supercooler, At least one heat exchange passage is provided on the condensation part and the supercooling part, and the heat exchange passage is composed of a plurality of heat exchange tubes arranged in parallel with the longitudinal direction facing the left and right directions and spaced apart from each other in the vertical direction. The refrigerant flowing out of the cooling part flows into the supercooling part through...
