Title:
HEAT EXCHANGER, REFRIGERATION CIRCULATION SYSTEM, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/040240
Kind Code:
A1
Abstract:
A heat exchanger (100), comprising: a heat exchanger main body, which is provided with at least one refrigerant inlet and outlet (111, 112) and a plurality of heat exchange branches (120); a second liquid separator (212), which is provided with a confluence pipe port and a plurality of liquid separation ports (221), the second liquid separator (212) being vertically or obliquely arranged so that the liquid separation ports (221) face upward and the confluence pipe port faces downward, or the liquid separation ports (221) being arranged obliquely upward and the confluence pipe port being arranged obliquely downward, and when the heat exchanger (100) is used as a condenser, at least one among the liquid separation ports (221) being used for liquid intake and at least one among the liquid separation ports (221) being used for liquid discharge; and a first one-way valve (311), the flow direction of which is restricted to be connected when the heat exchanger (100) is used as an evaporator, and to be blocked when the heat exchanger (100) is used as a condenser so as to allow the second liquid separator (212) to converge and store a liquid. According to the heat exchanger (100), part of a refrigerant can be stored by using the second liquid separator (212), and the second liquid separator (212) is vertically or obliquely arranged according to a means in which the liquid separation ports (221) face upward and the confluence pipe port faces downward.
