As disclosed in Japanese Utility Model Laid-Open No. 62-189527 as a prior art, the mounting structure of the reactor 6 has the opening 2a at a portion facing the reactor 6 as shown in FIGS. Since the reactor 6 is formed to expose the reactor 6 to the heat exchanger chamber to radiate heat, an effect of effectively preventing an excessive temperature rise is obtained. In order to further improve the heat dissipation effect, as another embodiment, as shown by a broken line in FIG. 2B, a heat dissipation fin 6b made of a metal material having good heat conductivity such as aluminum is installed in the reactor 6. It is attached to the mounting plate 6a and is provided so as to project into the heat exchanger chamber through the opening 2a of the partition plate 2. However, in the mounting structure of the reactor 6, the mounting plate 6a provided with the mounting hole of the reactor 6 is attached to the locking portion 2b provided on the compressor chamber inner surface of the partition plate 2 made of a steel plate. Since one side of the mounting plate 6a is locked and the other side is mounted and fixed by the screw 9 which is inserted through the mounting hole into the screw hole, when the same screw 9 is screwed into the screw hole. In order to improve the strength of the main body 1, it is necessary to take measures such as continuously forming a protrusion in the same screw hole to reinforce it. However, the intrusion of rainwater into the main body 1 forms and reinforces the protrusion. There is a problem that rust is generated in the screw hole and the strength of the portion is lowered, and the attachment strength of the reactor 6 becomes insufficient.
