HEAT EXCHANGER AND REFRIGERANT PASSAGE PORTION CONNECTING STRUCTURE FOR REFRIGERATION CYCLE

WIPO Patent Application WO/2005/108898

A1

Fixed to the peripheral wall of a header 2 of a unit-type heat exchanger 1 is a receiver connecting block 6 having channels 31, 32 for causing the interior of the header 2 to communicate with the interior of a liquid receiver 7 therethrough. The block 6 and the liquid receiver 7 have respective fixing portions 32, 36 and respective contact faces 22a, 36a each provided on the fixing portion. The outer peripheral surfaces of the fixing portions 22, 36 have respective contours of the same shape and the same size. The liquid receiver 7 is fixed to the block 6 with the contact faces 22a, 36a of the fixing portions 22, 36 in intimate contact with each other. A tubular seal member 42 having rubber elasticity is liquid-tightly fitted around the fixing portions 22, 36. The seal member 42 has an inner shape smaller than the contours of the outer peripheral surfaces of the fixing portions 22, 36 and is fitted as elastically deformed around the fixing portions 22, 36. Rainwater or the like can be prevented from ingressing into an interstice between the contact faces of the block and the liquid receiver.
