HEAT EXCHANGER, REFRIGERATION SYSTEM, AIR CONDITIONER, AND METHOD AND APPARATUS FOR FABRICATING HEAT EXCHANGER

摘要

A PLURALITY OF HEAT TRANSFER TUBES ARE DISPOSED AT CERTAIN INTERVALS, IN TUBE OPERATING FLUID (SUCH AS COOLANT) PASSES THERETHROUGH, AND A PLURALITY OF SMALL-GAGE WIRES (2) ARE USED AS A HEATING FIN. ONE SMALL-GAGE WIRE (2) IS WOUND AT A PAIR OF HEAT TRANSFER TUBES (1A) AND (1C) IN A SPIRAL MANNER, AND ANOTHER SMALL-GAGE WIRE IS WOUND AT A PAIR OF HEAT TRANSFER TUBES (1B) AND (1C) IN THE SPIRAL MANNER, AND STILL ANOTHER SMALL-GAGE WIRE IS SOUND AT A PAIR OF HEAT TRANSFER TUBES (1B) AND (1D) IN THE SPIRAL MANNER. THEREBY, WHILE HIGHER HEAT TRANSFER COEFFICIENT CAN BE ACHIEVED, AND A HEATING SURFACE AREA IS ENSURED, CLOGGING CAN BE AVOIDED EVEN WHEN MOISTURE IN AIR CONDENSES ON A SURFACES OF A HEAT EXCHANGER. AS A RESULT, IT IS POSSIBLE TO REALIZE A HIGH-PERFORMANCE AND COMPACT HEAT EXCHANGER USED FOR AIR CONDITIONING.FIG.1
