A heat-exchanging plate member has a pair of heat-exchanging plates, each of which has projection ribs and fluid passage forming portions arranged alternately. The pair of plates are connected to each other in a manner that the projection ribs formed in the plates, respectively, face outwardly with each other, and the projection ribs formed in one of the plates are connected to the fluid passage forming portions formed in the other of the plates, respectively, at a temperature where the strength of material is not lowered in a connecting process.

This application is based upon Japanese Patent Application No. 2002-113174, filed on Apr. 16, 2002, the contents of which are incorporated herein by reference.
1. Field of the Invention
The present invention relates to an exhaust gas heat exchanger in which an internal fluid passage is formed by using plate-like members. Specifically, the present invention relates to thinning the thickness of the plate-like members which are disposed adjacent with each other.
FIG. 1 is a diagram showing a relationship between tensile strength/proof strength of Aluminum A1100-H material and the annealing temperature when the Aluminum material is used to manufacture core material in the related art;
FIG. 2 is a disassembled perspective view of an evaporator according to a first embodiment of the present invention;
FIG. 3A is a partial cross-sectional view taken along line III-III in the first embodiment of the present invention;
Specific embodiments of the present invention will now be described hereinafter with reference to the accompanying drawings in which the same or similar component parts are designated by the same or similar reference numerals.
A first preferred embodiment of the present invention will now be described with reference to FIGS. 2 to 6. In this embodiment, an evaporator 10, which is typically employed, for example, as a refrigerant evaporator for a vehicle air conditioner, is provided as a perpendicular-flow type heat exchanger in which a stream direction A of conditioning air is approximately perpendicular to a stream direction B (an up-down direction in FIG. 1) of refrigerant flowing in a heat-exchanging plate member 12.
The evaporator 10 has a core portion 11 for performing a heat-exchange between the conditioning air (i.e., outside fluid) and the refrigerant (i.e., inside fluid), which is formed by plural heat-exchanging plate members 12 disposed adjacent with each other. Each heat-exchanging plate member 12 is formed as a pair of plates by combining a first heat-exchanging plate 12a with a second heat-exchanging plate 12b as shown in FIGS. 3A and 3B.
