The heat sink is distributed to the outside, but when the electrical components continue to increase the calorific value, the heat dissipation efficiency of the heat sink will not be satisfactory; the heat dissipation centrifugal fan (equivalent to the first adjustment part 41 and the second adjustment part 42) is installed and fixed on the bottom shell The upper side is turned on when the air conditioner is heating and heating respectively, and the cold air it blows out blows down through the electrical components, takes away the heat, and blows out from the air outlet below the bottom case. An angled frame is installed between the middle evaporator of the air conditioner and the electrical components on the left side. The angled frame (equivalent to the guide wall 70) is used to fix the evaporator on the one hand, and separates the evaporator from the electrical components on the other hand to prevent the evaporator from The condensed water enters the electrical components, the electrical components on the left form a channel (equivalent to the heat exchange flow channel 10), and the cold air blown in from above (equivalent to the first heat exchange port 13) can be directly blown to the air outlet below (equivalent to the third heat exchange port 15), and when the amount of heat dissipation is large, the exhaust fan 43 on the air outlet can also be installed and opened to increase the heat dissipation efficiency.
