HEAT EXCHANGER, MANUFACTURING METHOD THEREOF, AND REFRIGERATION CYCLE DEVICE USING THE HEAT EXCHANGER

摘要

PROBLEM TO BE SOLVED: To provide a heat exchanger having a structure excellent in quality stability and mass productivity compared with a conventional heat exchanger comprising a thin wire braided in a heat-transfer tube, a manufacturing method thereof, and a refrigeration cycle device using the heat exchanger. SOLUTION: The heat exchanger comprises two heat transfer plates holding the circumference of a heat transfer tube 11 in between. The first heat transfer plate 14 has a corrugated shape having a first mountain part 15 on the upper side 3 of the heat transfer tube 11 and a first valley part 16 between the heat transfer tube 11 and a heat transfer tube 11 adjacent thereto, and includes first protruding parts 22 formed by providing first opening parts 17 in the first valley part 16 at equal intervals. The second heat transfer plate 18 has a corrugated shape having a second valley part 19 on the lower side 4 of the heat transfer tube 11 and a second mountain part 20 arranged between the heat transfer tube, and includes second protruding parts 23 formed by providing second opening parts 21 in the second mounting part 20 at equal intervals.
