Referring to fig. 1, in this embodiment, an air conditioning unit easy to dissipate heat from an electric control box includes a box 1, an electric control box 2, and an air deflector 3. Further, a plurality of partition plates are disposed in the box 1, and each partition plate divides the internal space of the box 1 into an evaporation cavity 101, a condensation cavity 102 and a return air cavity 103.
Specifically, the evaporation chamber 101 is provided with an evaporation heat exchanger 401 and an evaporation fan 402, and the condensation chamber 102 is provided with a condensation heat exchanger 501 and a condensation fan 502.
Optionally, in this embodiment, the evaporation chamber 101 is located on the left side of the return air chamber 103, and the condensation chamber 102 is located above both the evaporation chamber 101 and the return air chamber 103. Of course, in some other embodiments, the condensation chamber 102 may be disposed in front of or behind both the evaporation chamber 101 and the return air chamber 103, which is not limited by the present utility model.
Further, a condensation air inlet 1021 is provided on the side surface of the condensation chamber 102, and a condensation air outlet 1022 is provided on the top of the condensation chamber 102. Under the driving action of the condensing fan 502, air in the outdoor environment enters the condensing cavity 102 through the condensing air inlet 1021, absorbs heat on the condensing heat exchanger 501, and returns to the outdoor environment through the condensing air outlet 1022.

Specifically, under the driving action of the evaporating fan 402, air in the space to be cooled directly enters the evaporating cavity 101 through the same-side evaporating air return port 1011a and/or sequentially enters the evaporating cavity 101 through the different-side evaporating air return port 1011b, the air return cavity 103 and the evaporating air inlet 1012, exchanges heat with the evaporating heat exchanger 401 in the evaporating cavity 101, absorbs cold energy, and returns to the space to be cooled through the evaporating air supply port 1031, so that servers and the like in the space to be cooled are cooled. In general, according to the relative positional relationship between the space to be cooled and the air conditioning unit that is easy to dissipate heat from the electric control box, the same-side evaporation return air inlet 1011a and the different-side evaporation return air inlet 1011b are alternatively used, and the evaporation return air inlets that are not needed are directly plugged by using a sealing plate or the like.

Further, one end of the air deflector 3 is mounted at the mounting window 1041, the other end of the air deflector extends into the evaporation cavity 101, and the shape of the air deflector 3 is matched with the shape of the rear end face of the electric control box 2, so that a cooling air duct 7 is reserved between the air deflector 3 and the electric control box 2, and the cooling air duct 7 is communicated with the evaporation cavity 101 to the return air cavity 103 through the mounting window 1041.
In this embodiment, the height dimension of the installation window 1041 is greater than the sum of the height dimension of the electric control box 2 and the thickness dimension of the air deflector 3, so after the electric control box 2 is installed and fixed at the bottom of the installation window 1041 and the air deflector 3 is installed and fixed at the top of the installation window 1041, the cooling air duct 7 can still be left between the electric control box 2 and the air deflector 3.

It should be noted that, when air flows in the cooling air duct 7, the surface air flow speed of the rear end face of the electronic control box 2 is increased, so as to increase the heat dissipation efficiency of the electronic control box 2. Optionally, a heat dissipation fin 201 is disposed on a side of the electric control box 2 close to the air deflector 3, so as to increase heat exchange area, further improve heat dissipation efficiency, and optimize heat dissipation effect.

And a temperature detection module in communication connection with the rotating motor is arranged in the electric control box 2.
Specifically, when the temperature detection module detects that the temperature tmeter of the electric control box 2 is higher, an instruction can be sent to the rotating motor, so that the wind shield rotates to a state of tending to be horizontal, the shielding effect of the wind shield on the cooling air duct 7 is reduced, the cold air flow in the cooling air duct 7 is increased, and the heat dissipation efficiency of the electric control box 2 is further improved; on the contrary, when the temperature detection module detects that the temperature tmeter of the electric control box 2 is lower, an instruction can be sent to the rotating motor, so that the wind deflector rotates to a state tending to be vertical, the shielding effect of the wind deflector on the cooling air duct 7 is increased, the cold air flow in the cooling air duct 7 is reduced, and the air intake of a space to be cooled is improved.
Generally, a temperature detection module is integrated in the driving circuit board, so that temperature data of the driving circuit board can be directly obtained. Taking temperature control by a temperature detection module in a driving circuit board as an example, setting the optimal working temperature of the driving circuit board to be T1 to T2 (T2 > T1), reading the actually measured temperature Ttest from the driving circuit board, and driving the wind shield to restore to an initial vertical state by the rotating motor every time the system is started so as to completely close the cooling air duct 7 (namely, the opening degree of the wind shield is 0 °), wherein the working logic of the rotating motor is as follows:
(1) If the opening degree of the wind deflector is 0 ° (the angle between the wind deflector and the vertical plane is 0 °):
(1) when T is measured to be more than T2, every x seconds, the rotating motor drives the opening of the wind shield to be increased by 1% (x is a preset value) until T is measured to be less than or equal to T2, stopping the rotating motor, and keeping the current opening;
(2) when T is less than or equal to T2, the rotating motor does not act;
(2) If the opening degree of the wind deflector is not 0 ° (the angle between the wind deflector and the vertical plane is not 0 °):
(1) when T is measured to be more than T2, every x seconds, the rotating motor drives the opening of the wind shield to be increased by 1% (x is a preset value) until T is measured to be less than or equal to T2, stopping the rotating motor, and keeping the current opening;
(2) if T is less than T1, every x seconds, the rotating motor drives the opening of the wind shield to be reduced by 1% (x is a preset value) until T is more than or equal to T1, stopping the rotating motor, and keeping the current opening;
(3) if T1 is less than or equal to T0 and less than or equal to T2, the rotating motor does not act, and the current opening degree is kept.
In some other embodiments, the temperature detecting module may also be a separate temperature detecting device such as a temperature sensor installed in the electronic control box 2, for detecting the temperature of the electronic control box 2 or other heat generating devices in the electronic control box 2, which is not limited by the present utility model.
The air conditioning unit easy to cool the electronic control box provided by the embodiment has the following advantages:
(1) the air deflector 3 is arranged on the side surface of the electric control box 2 to form the cooling air channel 7 which communicates the evaporation cavity 101 with the external space of the evaporation cavity 101, so that when air in the evaporation cavity 101 flows through the cooling air channel 7 under the action of the wind pressure of the evaporation fan 402, the electric control box 2 can be radiated, the radiating effect of the electric control box 2 is improved, power equipment such as a radiating fan and the like are not required to be newly added, electric energy is not required to be consumed, and the effects of energy conservation and emission reduction are achieved;
(2) the air quantity of the cooling air duct 7 can be controlled according to the actual temperature of the electric control box 2, and then dynamic balance adjustment is carried out between improving the heat dissipation efficiency of the electric control box 2 and improving the air quantity of the space to be cooled.
