The outdoor machine shell 1 is provided with an air inlet 14 and an air outlet 15 which are communicated with the fan cavity 12, and in the running process of the outdoor machine, the outdoor machine can drive air flow to enter the outdoor machine shell 1 from the air inlet 14, exchange heat with the outdoor heat exchanger 2, and then be discharged to the outside of the outdoor machine shell 1 through the air outlet 15 after exchanging heat.

The compressor assembly 3 includes a compressor, and the compressor assembly 3 may function to compress and drive a refrigerant in a refrigerant circulation circuit of the outdoor unit 100.

The electronic control box part 4 comprises a box body 41 and an electronic control module 42 arranged in the box body 41, wherein the box body 41 is provided with an air flow inlet 411 and an air flow outlet 412, the air flow inlet 411 is communicated with the compressor cavity 13, and the air flow outlet 412 is communicated with the fan cavity 12. The electronic control module 42 may be electrically connected to an outdoor fan, a compressor assembly 3, etc. provided in the outdoor housing 1, and may be used to control the operation of the outdoor fan, the compressor assembly 3, etc. During operation of the outdoor unit 100, the operation of the outdoor fan drives the air flow into the box 41 through the air inlet 411, and the air flow flows through the electronic control module 42 to perform air cooling and heat dissipation.

The heat dissipation pipe 7 is internally provided with a heat dissipation flow passage for flowing heat exchange medium, and the heat dissipation pipe 7 is in heat conduction connection with the electronic control module 42. The heat exchange medium takes away the heat on the electronic control module 42 in a flowing manner in the heat dissipation flow channel so as to realize heat dissipation of the electronic control module 42.

According to the outdoor unit 100 of the embodiment of the utility model, the box body 41 of the electric control box member 4 is provided with the air flow inlet 411 and the air flow outlet 412, and the radiating pipe 7 is arranged, so that in the working process of the outdoor unit 100, the operation driving air flow of the outdoor fan enters the box body 41 through the air flow inlet 411, the air flow flows through the electric control module 42 to perform air cooling radiation, and the heat on the electric control module 42 is taken away by the heat exchange medium in the radiating flow passage of the radiating pipe 7, so that the air flow entering the box body 41 through the air flow inlet 411 and the heat exchange medium in the radiating pipe 7 simultaneously radiate the electric control module 42, thereby being beneficial to improving the radiating efficiency and radiating effect of the electric control module 42, reducing or avoiding the adverse effect of the electric control box member 4 on the working of the outdoor unit 100 due to the high-temperature working condition, and further reducing or avoiding the adverse effect on the air conditioning capacity of the air conditioning equipment.

Referring to fig. 1 to 2, according to some embodiments of the present utility model, an outdoor unit casing 1 is formed with an air inlet 16, the air inlet 16 being located at a sidewall of a compressor chamber 13, and the air inlet 16 communicating an air inlet 411 with an external space of the outdoor unit 100. In the working process of the outdoor unit 100, the operation of the outdoor fan causes an air pressure difference between the inside of the fan chamber 12 and the outside space of the outdoor unit 100, so that the air flow in the outside space can enter the box body through the air inlet and the air flow inlet 411 under the action of the air pressure difference, then flows through the electronic control module 42 in the box body 41 and exchanges heat with the electronic control module 42 sufficiently to realize heat dissipation of the electronic control module 42, and then the air flow can flow out of the box body 41 through the air flow outlet 412 and enter the fan chamber 12.

In the working process of the outdoor unit 100, the temperature of the air flow in the outdoor unit 1 is higher, if the air flow in the outdoor unit 1 dissipates heat of the electronic control module 42 of the electronic control box component 4, the heat dissipation effect is poor, so that the air flow in the external space of the outdoor unit 1 dissipates heat of the electronic control module 42 to be beneficial to improving the heat dissipation effect, and further reducing or avoiding the electronic control box component 4 under the high-temperature working condition, thereby reducing or avoiding influencing the normal operation of the electronic control box component 4 due to high temperature and avoiding influencing the normal operation of the outdoor unit 100.

For example, when the outdoor unit 100 is applied to a variable frequency air conditioner, the air flow in the external space of the outdoor unit casing 1 dissipates heat to the electronic control module 42 to improve the heat dissipation effect, so that the outdoor unit 100 can be effectively prevented from self-limiting frequency and protecting due to the heat generated by the electronic control box component 4 under the high temperature working condition, and the air conditioner can achieve a good air conditioning effect.

In addition, by enabling the air inlet 411 to be communicated with the external space of the outdoor unit 100, in the working process of the outdoor unit 100, the operation of the outdoor fan can enable an air pressure difference to exist between the fan cavity 12 and the external space of the outdoor unit 100, so that the air flow in the external space can enter the box 41 through the air inlet 411 to dissipate heat of the electronic control module 42, and then the air flow flows out of the box 41 to the fan cavity 12 through the air outlet 412, and the air flow temperature in the external space of the outdoor unit 100 is lower than the air flow temperature in the outdoor unit 100, so that the air flow in the external space of the outdoor unit 100 dissipates heat of the electronic control module 42, thereby being beneficial to improving the heat dissipation effect.

During the operation of the outdoor unit 100, the operation of the outdoor fan causes an air pressure difference between the inside of the fan chamber 12 and the outside space of the outdoor unit 100, so that the air flow in the outside space enters the outdoor unit casing 1 through the air inlet 16 under the action of the air pressure difference, flows through the air inlet space 5 toward the air flow inlet 411 and can enter the box 41 through the air flow inlet 411 of the box 41, and flows through the electronic control module 42 and the electronic control module 42 in the box 41 to perform sufficient heat exchange to achieve heat dissipation of the electronic control module 42, and then the air flow can flow out of the box 41 through the air flow outlet 412 and enter the fan chamber 12.

Referring to fig. 1-2, in accordance with some alternative embodiments of the present utility model, the air intake 16 is located on a side of the compressor cavity 13 that is remote from the fan cavity 12 in a side-to-side direction. By locating the air inlet 16 on the side of the compressor chamber 13 away from the fan chamber 12 in the left-right direction, the sample air inlet 16 is located at a greater distance from the fan chamber 12, so that the influence of the air flow flowing out of the fan chamber 12 on the temperature of the air flow at the air inlet 16 is reduced, and the air flow entering the box 41 through the air inlet 16 is beneficial to effectively radiating the electric control module 42.
