Title:
HEAT EXCHANGER AND HEAT PUMP
Document Type and Number:
Japanese Patent JP2020016350
Kind Code:
A
Abstract:
To provide a heat exchanger whose maintenance frequency can be reduced, and whose maintenance can be easily performed.SOLUTION: A heat exchanger 13 comprises: a header 2 having a pipe-like shape extending along a first axis A1, and through which water flows in the direction of the first axis A1; and a branch pipe 4 into which the water flows from the inside of the header 2. The branch pipe 4 comprises: a connection pipe 42 protruding from the header 2 in the direction of a second axis A2 intersecting with the direction of the first axis A1, and communicating with the inside of the header 2; a heat transfer pipe 41 opposed to the connection pipe 42 in the direction of the second axis A2, and extending in the direction of the second axis A2; and a joint part 43 detachably connecting the connection pipe 42 and the heat transfer pipe 41 in the direction of the second axis A2. A material forming at least an inner peripheral surface 42A in the connection pipe 42 has higher corrosion resistance than that of a material forming the heat transfer pipe 41.SELECTED DRAWING: Figure 3
