Title:
HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2019190799
Kind Code:
A
Abstract:
To provide a heat exchanger in which a refrigerant inlet and a refrigerant outlet are arranged close to each other, and which can prevent the lowering of a capability for cooling cooling water.SOLUTION: A core part 3 possessed by a heat exchanger 1 is constituted of a plurality of plates 10 which are laminated with intervals so as to form a plurality of refrigerant flow passages 20 and a plurality of cooling water flow passages 30. Refrigerant inlet-side tank parts 21 and refrigerant outlet-side tank parts 22 make the plurality of refrigerant flow passages 20 communicate with each other in a lamination direction, and are arranged in separated positions. Refrigerant inlets 23 and refrigerant outlets 24 communicate with the refrigerant inlet-side tank parts 21 and the refrigerant outlet-side tank parts 22, respectively, and are arranged at one end part of the core part 3 in the lamination direction. Refrigerant inlet flow passages 25 make the refrigerant inlets 23 and the refrigerant inlet-side tank parts 21 communicate with each other. Then, an inter-center distance α between the refrigerant outlet-side tank parts 22 and the refrigerant outlets 24 is shorter than an inter-center distance β between the refrigerant inlet-side tank parts 21 and the refrigerant inlets 23.SELECTED DRAWING: Figure 3
