Outdoor machine of air conditioner

Abstract

The invention relates to an outdoor unit of an air conditioning machinery whose structure can improve a maintainability of electrical components and so on arranged in a control box and prevent foreign matter and so on from accumulating in the electrical components. Thereby, the outdoor unit of the air-conditioning machinery provided by the invention comprises a shell, a lower board forming the lower surface of the shell, a separating board dividing the internal of the shell into a compression chamber and a heat exchange chamber, and also comprises the control box which is provided with various components and arranged in the compression chamber. Because the control box leans a predetermined angle relative to the lower board to fix on the separating board, so that the invention not only canimprove the maintainability and reduce accumulation of foreign matter such as dust on the surface of a printed circuit board as far as possible, but also can form more compact compressor chamber.

Description

technical field [0001] The present invention relates to an outdoor unit of an air conditioner, and more particularly to an outdoor unit of an air conditioner having a control box for installing a circuit board and electrical components. Background technique [0002] Generally, an outdoor unit of an air conditioner includes a compressor for compressing refrigerant, an outdoor heat exchanger, and an exhaust fan for cooling the outdoor heat exchanger by forced air blowing of outside air. The interior space of the outdoor unit is divided into a space for setting the compressor and a space for setting the exhaust fan through a partition plate, and a control box for setting various electrical components and circuit boards is arranged on the upper part of the space for setting the compressor. [0003] The control box is used to control the movement of the internal parts of the outdoor unit and is equipped with multiple electronic components such as PCB. The electronic components bu...

Problems solved by technology

[0006] However, when the printed circuit board of the outdoor unit of the air conditioner disclosed in the publication has an inverter compressor, the number of electrical components and Electrical components are larger than normal compressors contain, so the size of the individual printed circuit boards that house them also becomes larger

[0007] Therefore, in the case where the control box provided with such a single printed circuit board is arranged horizontally with respect to the base, the outdoor unit may be damaged due to the large size of the control box. The size also becomes large, making it difficult to provide a compact outdoor unit

[0008]Furthermore, since the control parts built in the printed circuit board inside the control box are arranged upward, impurities such as dust accumulate on the printed circuit board, causing Misoperation and failure

[0009] Also, since the control box and cooling plate are located on the upper part of the partition, there is a problem of deformation of the partition due to the weight of the control box and cooling plate

Especially in the case of external shocks when moving, it may cause deformation of the partition

[0010] Moreover, the control box is fixed to the control placement part of the partition wall, but it is difficult to firmly fix the control box only by fixing to the control placement part

[0011] Moreover, the cooling device used to dissipate heat from the printed circuit board is set in a heat exchanger instead of a structure that can guide air to the cooling device, so there is a low cooling efficiency The problem
