を通って前述の吐出グリル１７から排出される。2 and 3 show the relationship between the partition plate 8, the electrical equipment board 22, and the cooling member 29. Reference numeral 34 indicates mounting holes for the transistor module 31. When you apply the screw to the first mounting hole 35 of the piece,
This transistor module 31 is fixed to the cooling member 29. Reference numeral 36 denotes a second mounting hole of the cooling member 29. When the cooling member 29 is slid downward with the upper end of the radiation fin 30 in contact with the upper end of the cover portion 37 of the insulating member 32, the cooling member 29 is removed. The lower part 37 of the insulating member 32 is engaged with the mounting piece 38 of the insulating member 32, and the second mounting hole 36 is connected to the boss 39 of the insulating member 32. is located in the cylindrical portion 40 of the insulating member 32. If you tighten the screw from the second mounting hole 36,
This cooling member 29 is fixed to the insulating member 32. 41 is a mounting hole of the insulating member 32, and while inserting the lower protruding piece 42 of this insulating member 32 into the mounting hole 43 of the electrical equipment board 22,
The projecting edge 44 of this member is connected to the left rising piece 2 of the electrical equipment board 22.
3, this mounting hole 41 matches the mounting hole 45 of the electrical equipment board 22, and is fixed with a screw. Note that the insulating member 32 is inserted into the notch portions 46 provided on both the left and right edges of the opening 33.
A boss 39 and a cylindrical portion 40 are located therein. In this way, electrical components (transistor module 31 and capacitor 25)
etc.) to the electrical equipment board 22, and then insert the upper positioning piece 47 of the electrical equipment board 22 into the upper mounting hole 48 of the partition plate 8. As shown in FIG. It is covered with an insulating member 32. When the heat exchange unit 1 configured in this manner is operated, outdoor air is sucked into the heat exchange unit 1 from the suction port 4 by the rotation of the blower 11, and heat is exchanged with the refrigerant flowing through the heat exchanger 10. Then, it is blown out from the discharge grille 17 on the front panel. At this time, the temperature of the air in the machine room 49 is rising due to heat radiation from the compressor 21, condenser 25, and the like. However, due to the rotation of the blower 11, the pressure in the heat exchange chamber 50 becomes lower than the pressure in the machine room 50.
The air inside passes between the fins 30 and is discharged from the above-mentioned discharge grille 17 as shown by solid arrows in FIG.

モジュール３１の破損を防止している。Here, for example, if a current leakage 7 occurs inside the heat exchange unit 1 or a lightning strike occurs on a utility pole near the heat exchange unit 1, the sheet metal parts such as the partition plates 8 of the heat exchange unit 1 may be damaged. Even if electricity flows through the parts, the cooling member 29
is insulated from the partition plate 8 by the insulating member 32, so that electricity does not flow to the cooling member 29 or the transistor module 31. This prevents the transistor module 31 from being damaged.

とができる。(G) Effects of the Invention As described above, the present invention exposes the cooling member provided with heat radiation fins for electrical components in the machine room of the housing to the heat exchange chamber through the opening of the partition plate, and Since an insulating member is provided between the cooling member and the partition plate, even if electricity is transmitted to the partition plate due to electrical leakage, the insulating member prevents the electricity from being transmitted to the electrical components attached to the cooling member. In addition, since the insulating member and the cooling member are installed between the cooling member and the partition plate, and the electrical components are directly fixed to the cooling member, the electrical components are reliably cooled. Abnormal heat generation of parts can be prevented.
