A total of 4 locations. Below, two places of an upper end part are demonstrated with reference to figures.

  FIG. 13 shows a state in which the side plate 3, the bracket 4, the bolt 5 with the washer 51 and the installation side member 6 constituting the fixing device are disassembled. First, the side plate 3 is aligned with a predetermined position with respect to the installation side member 6. As shown in FIG. 14, the side plate 3 is aligned with the installation side member 6 at a position where the through hole 32 a of the protruding piece portion 32 and the third opening 61 a 1 of the connecting wall portion 61 coincide. At this time, the protruding piece portion 32 is close to whether or not it contacts the connecting wall portion 61.

  Next, the bracket 4 is installed on the side plate 3 and the installation side member 6 while maintaining this state. The second outer support portion 42 is inserted into the opening formed by the first opening portion 60a and the second opening portion 61a with the main body portion 40 facing upward, and the first outer support portion 41 is the protruding piece. The bracket 4 is fitted so as to be located outside the portion 31. The female screw part 42a of the second outer support part 42 and the third opening 61a1 of the connecting wall part 61 coincide with each other, and the through hole 41a of the first outer support part 41 and the through hole 31a of the protruding piece part 31 coincide with each other. Thus, the bracket 4 is positioned.

  In the installed state of the bracket 4, as shown in FIGS. 4, 5, and 15, the inner support portion 43 is fitted between the protruding piece portion 31 and the protruding piece portion 32, and the intermediate support portion 44 is inserted into the protruding piece portion 32. The intermediate support portion 44 is in contact with the connecting wall portion 61 on the opposite surface. Further, the first outer support portion 41 contacts the outer surface of the protruding piece portion 31, the second outer support portion 42 contacts the connecting wall portion 61, and the intermediate support portion 44 and the second outer support portion 42 are for connection. The wall 61 is sandwiched.

  Next, as shown in FIG. 16, the side plate 3 and the installation-side member 6 are sandwiched and fixed by the bracket 4 by tightening the bolt 5 and applying a clamping force while maintaining the installation state of the bracket 4. Specifically, the male screw portion 50 of the bolt 5 is inserted from the through hole 41a, the through hole 31a, the through hole 32a, and the third opening 61a1 are inserted in order, and the male screw portion 50 is screwed into the female screw portion 42a.

In this state, the bolt 5 fastens the first outer support part 41 and the second outer support part 42 in a direction approaching each other, and the first outer support part 41 and the second outer support part 42 are connected to the protruding piece part 31. The connecting wall portion 61 of the installation side member 6 is pressed and pinched from the outside. By this tightening operation, the operation of connecting the heat exchanger 1 and the installation side member 6 using the fixing device of the heat exchanger 1 is completed. The connection procedure at the two lower end portions is the same as the two upper end portions except that the upper and lower portions are reversed, and the above description is incorporated.

  Furthermore, the action force which acts on each part by the clamping force which the fixing device of the heat exchanger 1 gives is demonstrated, referring FIG. In the state where the tightening by the bolt 5 is completed, the first outer support portion 41 and the second outer support portion 42 are tightened in a direction approaching each other. Since the second outer support portion 42 pushes the broken line portion of the connecting wall portion 61 shown in FIG. 3 from the outside, the broken line portion slightly deforms toward the first outer support portion 41 side. The connecting wall portion 61 is pushed toward the second outer support portion 42 by the intermediate support portion 44 outside the second outer support portion 42 in the width direction. As a result, the connecting wall portion 61 is clamped at a position separated in the width direction by the second outer support portion 42 and the intermediate support portion 44, and is thus fixed to the bracket 4 with a high coupling force.

  Since the first outer side support part 41 pushes the broken line part of the protruding piece part 31 shown in FIG. 3 from the outside by the head of the bolt 5 and the washer 51, this broken line part slightly deforms toward the second outer side support part 42 side. The protruding piece portion 31 is pushed outward by the one end portion 43a of the inner support portion 43 outside the first outer support portion 41 in the width direction. Accordingly, the protruding piece portion 31 is sandwiched at a position separated in the width direction by the first outer support portion 41 and the inner support portion 43, and is thus fixed to the bracket 4 with a high coupling force.

  The intermediate support portion 44 pushes the protruding piece portion 32 from the outside. The other end portion 43b of the inner support portion 43 presses the protruding piece portion 32 from the outer side outside the intermediate support portion 44 in the width direction.

  Furthermore, the action force which acts on each part by the clamping force which the fixing device of the heat exchanger 201 gives will be described with reference to FIG. In a state where the tightening by the rivet 105 is completed, the first outer support portion 241 and the second outer support portion 242 are tightened in a direction approaching each other. Since the second outer support portion 242 pushes the broken line portion of the connecting wall portion 61 shown in FIG. 31 from the outer side, the broken line portion slightly deforms toward the first outer support portion 241 side. The connecting wall portion 61 is pushed toward the second outer support portion 42 by the intermediate support portion 244 on both sides in the width direction of the broken line portion of the connecting wall portion 61. As a result, the connecting wall portion 61 is sandwiched between the second outer support portion 42 and the intermediate support portion 44, and is thus fixed to the bracket 204 with a high coupling force.

  Since the first outer support portion 241 pushes the broken line portion of the protruding piece portion 31 shown in FIG. 31 from the outside by the head of the rivet 105, the broken line portion slightly deforms toward the second outer support portion 242 side. The protruding piece portion 31 is pushed outward by the one side end portion 243a of the inner support portion 243 on both sides in the width direction of the broken line portion of the protruding piece portion 31. Thereby, since the protruding piece part 31 is clamped by the first outer support part 241 and the inner support part 243, it is fixed to the bracket 4 with a high coupling force.

  The intermediate support portion 244 pushes the protruding piece portion 32 from the outside. The other end portion 243b of the inner support portion 243 pushes the protruding piece portion 32 from the outside at a position overlapping the inner support portion 243 in the thickness direction. Thereby, since the protruding piece 32 is sandwiched between the inner support portion 243 and the intermediate support portion 244 at two positions separated in the width direction, the protruding piece portion 32 is fixed to the bracket 204 with a high coupling force. Due to the above acting force, the side plate 3 of the heat exchanger 201 is firmly fixed to the installation side member 6 via the bracket 204.

  The effects provided by the third embodiment will be described. The fixing device of the heat exchanger 201 has the same effects as the fixing device of the heat exchanger 1 described in the first embodiment.

  The inner support portion 243 is provided at a position overlapping the first outer support portion 241 in the direction in which the first outer support portion 241 and the second outer support portion 242 face each other. According to this structure, since the range in the width direction for supporting one of the protruding pieces of the side plate 3 can be reduced, the size of the bracket 204 can be reduced while securing the coupling force between the heat exchanger 201 and the bracket 204.

  The intermediate support portion 244 is provided at a position overlapping the second outer support portion 242 in the direction in which the first outer support portion 241 and the second outer support portion 242 face each other. According to this configuration, since the range in the width direction that supports a part of the installation side member can be reduced, the size of the bracket 204 can be reduced while securing the coupling force between the heat exchanger 201 and the bracket 204.

  The intermediate support portion 244 and the inner support portion 243 sandwich the other of the pair of protruding piece portions 31 and 32. The intermediate support part 244 is provided at a position overlapping the inner support part 243 in the direction in which the first outer support part 241 and the second outer support part 242 face each other. According to this configuration, since the range in the width direction that supports the other of the pair of projecting pieces 31 and 32 can be reduced, the size of the bracket 204 can be reduced while securing the coupling force between the heat exchanger 201 and the bracket 204. I can plan.
