[embodiment 3]
Next, with reference to the accompanying drawings embodiments of the invention 3 are described.
Figure 12 illustrates the cross section structure of the heat exchanger of embodiment 3, and represents accordingly with above-mentioned Fig. 2.Change the direction of upstream side end plate, and change the structure of upstream side end plate and downstream end plate.
As shown in figure 12, the upstream side end plate 92 of heat exchanger 90 is made up of end plate main body 101 and support plate 102, end plate main body 101 is " コ " shape from cross-section and is connected with center housing 31, and support plate 102 engages with this end plate main body 101 and supporting hot exchanging tube 34.
