Title:
HEAT EXCHANGER AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2017/149989
Kind Code:
A1
Abstract:
This heat exchanger (10) includes: heat-transfer pipes (20); a header part to which one end of the heat-transfer pipes (20) is connected so as to be in communication with an internal space; a flow passage (56) that is connected to the inside of the header part so as to be in communication therewith and that has a refrigerant flowing therethrough; a main vertical partition plate (60) that divides a horizontal cross-section of the inside of the header part into an outflow-side region (63) that is connected to the heat-transfer pipes (20) and an inflow-side region (64) that is connected to the flow passage (56); and an inflow-side vertical partition plate (70) that divides a horizontal cross-section of the inflow-side region (64) into a first chamber (71) and a second chamber (72) that are adjacent to each other in the circumferential direction of the header part and that are in communication with the flow passage (56). A section of the main vertical partition plate (60) facing the first chamber (71) has formed therein a first horizontal through hole (61) that allows the first chamber (71) to communicate with the outflow-side region (63). A section of the main vertical partition plate (60) facing the second chamber (72) and at a different vertical-direction position from the first horizontal through hole (61) has formed therein a second horizontal through hole (62) that allows the second chamber (72) to communicate with the outflow-side region (63).
