Title:
HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2022021679
Kind Code:
A
Abstract:
To provide a heat exchanger capable of improving its heat exchange efficiency between heat media.SOLUTION: In a primary cooling system 100, a primary heat medium depressurized by an expansion valve 106 and a flow divider is introduced from an introduction port 350 of a heat exchanger 300 to a distributor 340 and equally flow-divided into a plurality of circuits of a coil 322. The primary heat medium flowing in the coil 322 in a shell 310 is joined in a suction header (joint manifold) 342, and delivered from the introduction port 352. On the other hand, in a secondary cooling system 200, secondary heat medium compressed by a refrigerator 204 is introduced from an introduction port 360 in the upper part of the shell 310 into a cylinder part 312, and passes between plate fins 324 of a plate fin coil body 320. At this time, it is subjected to heat exchange with the primary medium in the coil 322. The secondary heat medium liquefied by the heat exchange is delivered from a delivery port 362 on the lower side and fed to the expansion valve 206.SELECTED DRAWING: Figure 1
