Abstract

PURPOSE:To enable a radiation part to be cooled by a method wherein a heating part of an invertor device is arranged in the midway of a line communicating an outer part with the interior of a fan casing and the outer air is flowed into the fan casing through the air passage. CONSTITUTION:When an air conditioner is started to operate, a lateral flow fan is rotated and surrounding atmosphere is sucked through a surrounding atmosphere suction port 15 and at the same time since the position of the fan casing opening 9 is located at the suction side of the lateral flow fan, the air is sucked from this opening 9 (Arrow A). Due to this fact, an inner pressure at the fan motor storing part (b) is decreased and the air at the storing part (c) is sucked from the invertor opening 8 arranged at the partition plate 7-2. Then, the surrounding atmosphere at the storing part (c) is sucked through the opening hole 10 (arrow C) passed through the heat sink 6, (arrow B) and flowed toward the invertor opening 8. Under operation of the lateral flow fan 2, the heat sink 6 is forcedly cooled.

Conventionally, in inverter tower-mounted air conditioners, the heat generated by the inverter's main circuit transistors, rectifier diodes, etc. has an adverse effect on its own elements and electronic components installed nearby. It was necessary to take measures such as installing a heat sink and forcing ventilation through ventilation. For example, Utsukai Showa 57-178122
The publication discloses an inverter tower-mounted air conditioner that performs forced cooling through ventilation. This air conditioner is the third
To explain with reference to the figure, the outdoor unit 3) has a pressure unit 3 inside.
2. An outdoor heat exchanger 33, a propeller fan 34, and an inverter device storage box 35 are housed. The inverter storage box 35 has an outside air outlet 36. A ventilation port 37 is provided that opens on the suction side of the propeller fan 34.
The propeller flow circulates and cools the inverter device inside the storage box 35. However, when a cross-flow fan is used as the heat exchanger blower,! ? As shown in Figure 14, the external and cross-flow fan 40
Since the air is blocked by the fan casing 41 and the shielding plate 42, it was not possible to ventilate the heat generating part of the inverter device. For this reason, in inverter tower-mounted air conditioners that use a cross-flow fan as the heat exchanger blower, the only way to cool the heat-generating part of the inverter is to install a unique cooling fan or to rely on natural heat radiation. . Among these methods, the former requires a separate cooling fan, making the structure complex and expensive, while the latter requires a very large heat sink, resulting in an increase in the size of the equipment and [Objective of the Invention] The present invention is an inverter-mounted air conditioner that uses a transverse wave fan as a heat exchanger blower. An object of the present invention is to obtain an inverter tower-mounted air conditioner that can cool a heat radiation part of an inverter device with a simple configuration.
