Outside unit of air conditioning apparatus

Abstract

In an outdoor unit of an air conditioner, the inner part of machine casing is divided into a heat exchange chamber and a machine chamber by a partition plate. The heat exchange chamber accommodates a heat exchanger and an air blower. The machine chamber accommodates a compressor, an electrical installation box and a liquid accumulator. A reinforcing plate is adhibited on the partition plate. The liquid accumulator is installed on the partition plate through the reinforcing plate. The back surface of partition plate and reinforcing plate are fixed on the tube plate of heat exchanger together. The electrical installation box is provided with a first supporting plate which extends on the partition plate with a width approximately same to that of partition plate and supports the substrate of heat exchanger at the side of machine chamber. The back surface of the first supporting place can be temporarily fixed on the rib of tube place of heat exchanger at a state that the upper surface of partition plate loads the first supporting plate. Furthermore, the heat exchanger which is formed by curving a plurality of laminated finned tube type heat exchange parts and is formed with a step part at one end is provided in the machine casing. A guiding plate which guides the external air into the step part is also provided in the machine casing. The fixing part of guiding plate is installed on the heat exchange part configured at the inner side, and furthermore the side surface of guiding plate is installed on the baseboard of machine casing. A clearance for the outer gas flowing is provided between the side surface and the end of heat exchange parts which are configured at the outside.

Description

technical field [0001] The invention relates to an outdoor unit of an air conditioner. Background technique [0002] It is generally known that a frame is divided into a heat exchange chamber and a mechanical chamber by a partition, a heat exchanger and a blower are accommodated in the heat exchange chamber, and a compressor, an electrical installation box (electrical box) and a liquid accumulator are accommodated in the mechanical chamber. The outdoor unit of the air conditioning unit. In recent years, in order to try to realize the miniaturization of the machine room, a scheme in which a compressor and an accumulator are arranged up and down in the machine room, and the accumulator is mounted on a bulkhead has been proposed (for example, refer to Japanese Patent Application Laid-Open No. Publication No. 09-243115). It is also proposed that the electrical installation box is arranged substantially horizontally on the partition plate, and one end of the electrical installa...

AI Technical Summary

Problems solved by technology

Therefore, in the step portion of the heat exchanger, outside air does not flow smoothly, and the step portion does not contribute to heat exchange, so there is a problem that the heat exchange efficiency of the heat exchanger is low.
