Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2016/072719
Kind Code:
A1
Abstract:
Disclosed is a heat exchanger enabling, in one apparatus, heat exchange between two different types of cooling water and a refrigerant, and capable of efficiently forming a heat exchange rate between the two types of cooling water and the refrigerant. The heat exchanger has a refrigerant flow channel by comprising a refrigerant inlet into which a refrigerant flows and a refrigerant outlet through which a refrigerant is discharged, and has a cooling water flow channel through which cooling water, which is heat-exchanged with a refrigerant flowing through the refrigerant flow channel, flows, wherein the cooling water flow channel is composed of a first cooling water flow channel through which first cooling water flows and a second cooling water flow channel through which second cooling water, which is a type different from that of the first cooling water, flows, and the heat exchanger is divided into a first heat exchange section in which heat exchange, between the first cooling water of the first cooling water flow channel and the refrigerant, is carried out, and a second heat exchange section in which heat exchange, between the second cooling water of the second cooling water flow channel and the refrigerant, is carried out, thereby enabling heat exchange to be carried out independently. Therefore, heat exchange between two different types of cooling water and a refrigerant is carried out in a single heat exchanger, thereby enabling the implementation of a triple heat exchanger, and heat exchange efficiency can be improved by using cooling water of a stack side having a relatively high waste heat, and the optimum heat exchange effect can be obtained by controlling the ratio of the number of stages in a water-cooled condenser according to the amount of heat from the stack side and an electrical device side.
