Problems solved by technology

[0002] At present, large-scale units are equipped with electric control boxes, and the components in the electric control boxes generate a lot of heat. If the heat generated is not evacuated in time, the temperature rise test of the air conditioning unit will fail, and in severe cases, the unit will fail.
At present, the cooling method adopted by some units is to set louvers on the shell of the electric control box, but if the number of louvers is small, it is not conducive to heat dissipation, and it is easy to cause the unit to malfunction; if there are too many louvers, because large units are generally placed in In the open air, it is easy to cause rainwater to infiltrate and burn components; some use a cooling fan in the unit, which will lead to an increase in cost, and the increase in control components will increase the product failure rate

Embodiment 1

[0022] Such as figure 1 , figure 2 As shown, the present invention provides an air conditioner unit, comprising an electric control box 1, a condenser 2, a heat exchange fan 3 used in conjunction with the condenser, and a shell surrounding the condenser 2 and the heat exchange fan 3, the heat exchange fan 3 A negative pressure zone 4 is formed between the hot fan, the condenser and the shell, and the electric control box is provided with a heat exchange hole 9 and an air inlet 10, and the heat exchange hole 9 is connected to the negative pressure zone through the heat exchange tube 7. 4 communicates, and the air inlet 10 communicates with the atmosphere.

[0023] The point where the heat exchange tube 7 is connected to the negative pressure zone 4 is lower than the highest point of the heat exchange tube 7 . After this setting, even if the unit is placed in the open air, it can effectively prevent rainwater from entering the electric control box from the heat exchange tube....

Embodiment 2

[0030] Such as image 3 As shown, the biggest difference between this embodiment and Embodiment 1 is that there is no drainage bend at the top of the heat exchange tube. The nip is connected. The height difference between the point where the heat exchange tube is connected to the negative pressure area and the highest point is 50cm, because this distance is long enough to completely prevent the intrusion of rainwater and the like.

Abstract

The invention provides an air conditioning unit which comprises an electric control box, a condenser, a heat exchange fan matched with the condenser for use and an outer shell surrounding the condenser and the heat exchange fan. A negative pressure area is formed among the heat exchange fan, the condenser and the outer shell, and a heat exchange hole and an air inlet hole are formed in the electric control box. The heat exchange hole is communicated with the negative pressure area through a heat exchange tube, and the air inlet hole is communicated with the atmosphere. According to the air conditioning unit, the heat exchange fan of the air conditioning unit is used for cooling the electric control box, a control object does not need to be additionally arranged, control is simple, and operation is stable and reliable.

Description

technical field [0001] The invention relates to an air-conditioning unit, in particular to an air-conditioning unit which utilizes a heat-exchanging fan of the unit to take away heat from an electric control box. Background technique [0002] At present, large-scale units are equipped with electric control boxes, and the components in the electric control boxes generate a lot of heat. If the heat generated is not evacuated in time, the temperature rise test of the air conditioning unit will fail, and in severe cases, the unit will fail. At present, the cooling method adopted by some units is to set louvers on the shell of the electric control box, but if the number of louvers is small, it is not conducive to heat dissipation, and it is easy to cause the unit to malfunction; if there are too many louvers, because large units are generally placed in In the open air, it is easy to cause rainwater to infiltrate and burn components; some use a cooling fan in the unit, which will ...
