HEAT CONDUCTION TUBE ASSEMBLY STRUCTURE FOR HEAT EXCHANGER AND REFRIGERATION SYSTEM AND AIR CONDITIONING SYSTEM USING THE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To increase a heat conduction area for improving the heat conductivity of refrigerant by arranging a zigzag metal piece in the inside of a heat conduction tube set and forming an evaporation heat conduction piece set of a continuous U-shaped metal piece. ;SOLUTION: In the case of using in an evaporation type condenser for an air conditioner, a plurality of heat conduction tube set 5 and a plurality of evaporating heat conduction piece sets 4 are stacked alternately. On the left edge part of this structure an upright introduction tube 7 of refrigerant is provide, and a plurality of connecting tubes 1 are connected parallel to the introduction tube 7. An end plate 3 is arranged on both sides in the upper part of the lower part, and an end plate 8 is arranged on both sides of the upper part thereof. Further, vertical fixing plates 2 and 6 are provided to prevent a stacked structure from moving in the lateral direction. On the right edge part of the heat conduction tube set 5 is provided an extended connecting tube 9, and the tip parts of the plurality of connecting tubes 9 are connected to an upright confluence tube 10.;COPYRIGHT: (C)1999,JPO
