Embodiment approach 1
[0045] The basic structure of the plate heat exchanger 30 of Embodiment 1 is demonstrated.
[0046] figure 1 is a side view of the plate heat exchanger 30 . figure 2 It is a front view (a figure seen from the stacking direction) of the reinforcing side plate 1 . image 3 is the front view of heat transfer plate 2 (first plate). Figure 4 is a front view of the heat transfer plate 3 (second plate). Figure 5 It is a front view of the side plate 4 for reinforcement. Figure 6 It is a figure which shows the state which laminated|stacked the heat transfer plate 2 and the heat transfer plate 3. Figure 7 It is an exploded perspective view of the plate heat exchanger 30 .
[0047] In Embodiment 1, the heat transfer plates 2 and 3 are different heat transfer plates manufactured using different molds, for example.
[0048] Such as figure 1 As shown, the plate heat exchanger 30 alternately stacks heat transfer plates 2 and heat transfer plates 3 . In addition, in the plate hea...
Embodiment approach 2
[0085] In Embodiment 1, the first outflow port 10 and the second outflow port 12 sides of the heat transfer plates 2 and 3 are not particularly described. In Embodiment 2, the first outflow port 10 and the second outflow port 12 sides of the heat transfer plates 2 and 3 will be described.
[0086] Figure 21 to Figure 23 It is a figure which shows the heat transfer plate 2 of Embodiment 2. Figure 21 It is a partial front view showing a part of the heat transfer plate 2 according to the second embodiment. exist Figure 8 In, the first inflow port 9 and the second inflow port 11 side of the heat transfer plate 2 are shown, and in Figure 21 In , the first outflow port 10 and the second outflow port 12 side of the heat transfer plate 2 are shown. Figure 22 yes Figure 21 The H-H' section view. Figure 23 yes Figure 21 The I-I' section view.
[0087] Figure 24 to Figure 26 It is a figure which shows the heat transfer plate 3 of Embodiment 2. Figure 24 It is a partia...
Embodiment approach 3
[0098] In Embodiment 3, a case where a type of heat transfer plates are alternately laminated in different directions to form a plate heat exchanger will be described. Changing the direction of the heat transfer plate means to rotate the heat transfer plate by 180 degrees so as to replace the positions of the first inflow port 9 and the second outflow port 12 .
[0099]In addition, the plate heat exchanger 30 of Embodiment 3 has the same shape as that of the plate heat exchanger 30 of Embodiment 2 in principle, and only the relationship between the top width and the bottom width of the corrugated portion is different. Therefore, here, only the relationship between the top width and the bottom width of the wave-shaped portion will be described.
[0100] Since a plate heat exchanger is formed by stacking one type of heat transfer plate alternately in different directions, the heat transfer plates 2 and 3 are of the same type and differ only in direction.
[0101] Therefore, the...
