HEAT EXCHANGER AND VENDING MACHINE PROVIDED WITH THE HEAT EXCHANGER

摘要

PROBLEM TO BE SOLVED: To enhance security to prevent a flammable refrigerant to leak into a semi-hermetical space and catch fire therein in a heat exchanger for vending machines using the flammable refrigerant. SOLUTION: The heat exchanger is constituted of a heat transfer tube 17 bent in a meandering shape at approximately 180 degree for each bend and planer fins 18 which overlap with each other with a space therebetween and in which the heat transfer tube 17 is inserted and fixed. The risk of leak of a flammable refrigerant can be minimized using the heat exchanger wherein the meandering heat transfer tube 17 has no joint part. COPYRIGHT: (C)2005,JPO&NCIPI
