Liquid tank structure of heat exchanger

Abstract

In a liquid tank structure of a heat exchanger, a liquid tank 4 is attached to a heat exchanger having a heat exchanger core defining a condensation part AC and an under cooling part BC, and a pair of headers 1 and 2 each having an inlet part R 1, R 2 connected with the condensation part AC and an outlet part R 3, R 4. The condensed refrigerant from the inlet part R 2 flows in the liquid tank 4 through an inlet port 1 a of an inlet-port side connecting pipe 4 a connected with the inlet part R 2 of one header 2 of the pair of header. The condensed refrigerant Q accumulated in a bottom portion of the liquid tank 4 is discharged to the outlet part R 3 through an outlet port b 1 of an outlet-port side connecting pipe 4 b connected with the outlet part R 3 at a position under an inlet port a 1. A sloshing suppression member 11, for suppressing a sloshing of the condensed refrigerant Q accumulated in the bottom portion of the liquid tank 4, has a passing-through ability of the condensed refrigerant and is provided in an inner space of the liquid tank 4 between the inlet port a 1 and the outlet port b 1.
