Embodiment Construction

[0058] Embodiments of the present invention will be described below with reference to the drawings. This embodiment is an inventive heat exchanger used as an evaporator in a motor vehicle air conditioning unit.

[0059] 1 and 2 show the overall structure of an evaporator of a motor vehicle air conditioner to which a heat exchanger according to the present invention is applied, FIGS. 3-7 and 9 show the structure of main parts, and FIG. 8 shows a method of manufacturing a joint plate. Furthermore, Figure 10 shows how the refrigerant flows through the evaporator.

[0060] 1 and 2 show an evaporator 1 for an air conditioner in which a chlorofluorocarbon refrigerant is used. The evaporator 1 includes an aluminum refrigerant inlet-outlet tank 2 and an aluminum refrigerant diversion tank 3 arranged vertically spaced apart, and a heat exchange core 4 arranged between the two tanks 2 , 3 .

[0061] The refrigerant inlet-outlet box 2 includes a refrigerant inlet header 5 arranged at t...

Abstract

A semifinished joint plate 60 has a refrigerant inlet portion 45 and a refrigerant outlet portion 46 spaced apart in the front-rear direction. The semifinished plate 60 has an upwardly or downwardly extending slit 61 formed between the inlet portion 45 and the outlet portion 46, and slit width adjusting portions 62, 63 extending through the thickness of the plate 60, having a larger width than the slit 61 and communicating respectively with the upper and lower ends of the slit 61. A portion of the semifinished plate 60 above the upper adjusting portion 62 and a portion thereof below the lower adjusting portion 63 are bent to shorten the plate.

Description

[0001] Cross References to Related Applications [0002] This application was filed pursuant to 35 U.S.C. §111(a) and provisional application No. 60 filed under 35 U.S.C. §111(b) on April 7, 2004 pursuant to 35 U.S.C. §119(e)(1) Filing date benefit of / 559,961. technical field [0003] The present invention relates to a semi-finished joint plate, a joint plate, a method of manufacturing the joint plate and a heat exchanger, and in particular to a semi-finished joint plate for the manufacture of a joint plate used in a heat exchanger, a joint plate, a method of manufacturing the joint plate and heat exchangers. An exchanger which can be used as an evaporator in a motor vehicle air-conditioning unit, which is a refrigeration circuit to be installed in a motor vehicle.
