Problems solved by technology

[0006] However, the PCB of the existing frequency conversion window air conditioner is generally installed on the outdoor side and placed at the air inlet to cool the PCB. In order to improve the heat dissipation effect, it is generally equipped with a larger heat sink. The price of aluminum and aluminum is gradually rising. The heat sink made of pure copper or aluminum has a high cost, which directly increases the product price and reduces the market competitiveness of the product.
Moreover, due to the large heat generated by the inverter air conditioner PCB and the high outdoor temperature, the efficiency of heat exchange is greatly reduced, which poses a threat to the stability and life of the PCB board.
At the same time, the heat on the PCB heat sink is not only not fully utilized, but also affects the outdoor heat dissipation performance to a certain extent.

Embodiment Construction

[0017] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as Figure 1-4 As shown, the cooling-only window air conditioner of the present invention includes an indoor side 1 and an outdoor side 2, a heat exchange device 3 arranged on the indoor side 1 and a heat exchange device 4 arranged on the outdoor side, a compressor for compressing the refrigerant, and A printed circuit board (hereinafter referred to as PCB) 6 that can control the operation of the entire device. When it works normally, the refrigerant in the refrigeration cycle system goes through the refrigeration cycle in the order of evaporation-compression-condensation-expansion to realize the operation of the air conditioner in the cooling state. That is, the high-temperature and high-pressure gaseous refrigerant discharged ...

Abstract

The invention discloses a window type air conditioner which comprises an indoor side, an outdoor side and a PCB (printed circuit board) capable of controlling the operation of the whole device, wherein the PCB comprises a substrate, various circuit modules arranged on the substrate and a heat radiation device; the heat radiation device is a heat radiation block; the bottom of the heat radiation block is fixedly connected with a chip; and the upper surface of the heat radiation block is connected with an air suction pipe in which a low-temperature cooling medium flows in a contact manner. According to the invention, the air suction pipe in which the low-temperature cooling medium flows passes through the heat radiation block, and the heat radiation block is matched with a groove structure to be matched with the air suction pipe so as to increase the heat exchange area, so that the heat of the PCB in the maximum area can be transferred to the air suction pipe to increase the superheating degree, thereby improving the operation efficiency of the whole air conditioner and ensuring the operation safety of a compressor. In addition, while the heat is transferred to the air suction pipe, the temperature of the PCB is reduced, and the efficiency, working stability and service life of the PCB are increased.

Description

technical field [0001] The invention relates to a window-type air conditioner structure, in particular to a PCB cooling device for a window-type air conditioner. Background technique [0002] Generally speaking, an air conditioner is a cooling / heating household appliance installed on a wall of an indoor space such as an office or a home to cool or heat indoor air. The air conditioner consists of a compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger to form a refrigeration / heating cycle. [0003] Air conditioners are generally divided into ordinary air conditioners and inverter air conditioners according to the compressors installed inside their outdoor units, and both are composed of outdoor units and indoor units. [0004] The outdoor unit of the inverter air conditioner mainly includes a casing that constitutes the top surface and side external structure of the outdoor unit; a chassis that is arranged at the lower end of the casing and ...
