The branches 6, 7 consist of a first branch 6 extending in the left direction with reference to FIG. 1 and a second branch 7 extending in the right direction. In this embodiment, the first branch 6 is located between the inner wall of the heat exchanger 20 and the fin 22, and the second branch 7 is located between the fins 22 on both sides. Preference is given to washing (see FIG. 3). Here, the branch portion is illustrated as extending in two branches, but is not particularly limited thereto, and it is preferable that the branch portion extends at least two or more. For example, two branches may be extended in a left direction with respect to FIG. 1, and two branches may be extended in a right direction to constitute a total of four branches.

In addition, the distal end portions of the branch portions 6 and 7 extend in the vertical direction so that the injection portions 8 and 9 face each other. The injection parts 8 and 9 may include a first injection part 8 extending from the front end of the first branch part 6 and a second injection part 9 extending from the front end of the second branch part 7. It consists of. The injection parts 8 and 9 extend in parallel to face each other to inject high pressure washing water from both sides about the fins 22 of the heat exchanger 20.

On the other hand, in the present embodiment it is preferable that the injection portion (8, 9) is extended to different height (H) as shown in FIG. This is to more efficiently wash the heat exchanger (20). For example, when the spraying parts 8 and 9 spray each other at the same height, high pressure water is sprayed at the same time between the pins 22, so that the pins 22 are damaged and water is hard to fall out. there is a problem. In order to solve this problem, in the present embodiment, the injection parts 8 and 9 are extended to different heights so that the respective injection parts 8 and 9 can be efficiently washed between the pins 22 located at different heights. . In addition, in FIG. 1, the first injector 8 is shown to be positioned at a higher position than the second injector 9, but the present invention is not limited thereto, and the second injector 9 may be positioned at a higher position. have.

Next, the position fixing plate 11 is installed on one side of the first branch portion 6. The position fixing plate 11 is fixed by welding to the rear with respect to the first injection part 8.
