[0002] In the operation of a conventional air conditioner or other refrigeration product with an electric control cabinet, the electric control cabinet is generally in a flip structure for the convenience of periodical maintenance. In order to improve the heat dissipation effect, liquid cooling is generally used for heat dissipation of the electric control cabinet. However, the liquid cooling fins need to be in close contact with the frequency converter to achieve the cooling of the frequency converter. The flip structure of the electric control cabinet causes the frequency converter to be fixed on the electric control cabinet, which involves the flip of the liquid cooling fins. Since the connection pipe of the cooling fins needs to be considered for the connection of the hose, the flip will cause a large movement of the hose. The long-term operation of the product has poor reliability. Once the hose reaches the fatigue strength limit, it is easy to fail, which affects the heat dissipation and at the same time damages the use safety of the whole machine. SUMMARY

[0056] Referring to Figure 3 The mounting seat 110 is provided with a mounting hole 111, and the electric control cabinet 120 is rotatably mounted in the mounting hole 111 along the first rotation shaft, so that when the electric control cabinet 120 is in the working position, the electric control cabinet 120 can be in the mounting hole 111, which can reduce the volume of the electric control device 100 to a certain extent, and the mounting seat 110 has a simple structure and is easy to process, and in addition, the electric control cabinet can be protected.

[0057] In addition, referring to Figure 3 In order to avoid interference between the liquid cooling radiator 130 and the flipped electric control cabinet 120, the liquid cooling radiator 130 is arranged on one side of the mounting seat 110, and when the electric control cabinet 120 moves to the maintenance position, the end of the electric control cabinet 120 away from the first rotation shaft can move to the other side of the mounting hole 111, so that the air circulation is ensured and the heat dissipation effect is good.

[0060] Of course, in other embodiments, the first turning shaft can also be arranged at the middle of the electric control cabinet body 120. Specifically, the present application does not limit this.

[0061] In an embodiment, the mounting base 110 is provided with two mounting arms 112 extending along the hole depth direction of the mounting hole 111, and the two mounting arms 112 are arranged on the two sides of the mounting hole 111.

[0062] It should be noted that the mounting arm 112 can be cylindrical, square columnar or long strip-shaped formed by bending sheet metal.

[0065] In addition, there are various ways for the two ends of the mounting part 140 to be connected with the two mounting arms 112, for example, in an embodiment, the two ends of the mounting part 140 can be fixed with the two mounting arms 112 by welding, and in another embodiment, the two ends of the mounting part 140 can be fixed with the two mounting arms 112 by screwing. Specifically, the present application does not limit the connection mode between the two ends of the mounting part 140 and the two mounting arms 112.

[0066] The shape of the mounting part 140 is various, and in an embodiment, the mounting part 140 can be plate-shaped, referring to Figure 1In the embodiment of the present application, the mounting portion 140 comprises a support beam 141 connected with the two mounting arms 112 and two connecting arms 142 which are arranged in the length direction of the support beam 141 and extend in the length direction of the mounting arms 112, and the free ends of the two connecting arms 142 are connected with the liquid cooling radiator 130, so that the liquid cooling radiator 130 is more exposed to the air, and the cooling capacity radiated by the liquid cooling radiator 130 can be used as much as possible for the heat dissipation and cooling of the electric control cabinet body 120, thereby improving the heat dissipation efficiency.

[0067] The connecting mode between the two connecting arms 142 and the liquid cooling radiator 130 can be various, for example, in an embodiment, the connecting arm 142 and the liquid cooling radiator 130 can be fixed by welding, and in another embodiment, the connecting arm 142 and the liquid cooling radiator 130 can be fixed by screwing. Specifically, the present application does not limit the connecting mode between the connecting arm 142 and the liquid cooling radiator 130.

[0068] It should be noted that the shape of the two connecting arms 142 can be linear or can also be curved, and specifically, the present application does not limit this.

[0069] In actual use, there are electric control cabinet bodies 120 of different specifications, and therefore, the position of the liquid cooling radiator 130 needs to be adjusted according to the corresponding specification and size of the electric control cabinet body 120 to avoid interference therebetween. In an embodiment, the two ends of the mounting portion 140 are movably connected with the two mounting arms 112, so that the distance between the mounting portion 140 and the mounting seat 110 is adjustable, and thus the specific position of the liquid cooling radiator 130 can be adjusted as needed, so that the liquid cooling radiator 130 can be just in the appropriate heat dissipation position with the electric control cabinet body 120, thereby improving the heat dissipation effect.

[0070] The mode for realizing the adjustable distance between the mounting portion 140 and the mounting seat 110 can be various, for example, in an embodiment, the mounting portion 140 and the mounting arm 112 are connected by a sliding structure, the sliding structure comprises a sliding groove and a sliding table which are arranged in the length direction of the mounting arm 112 and are matched with each other, one of the sliding groove and the sliding table is arranged on the mounting portion 140, and the other is arranged on the mounting arm 112, and the mounting portion 140 can slide in the length direction of the mounting arm 112 relative to the mounting seat 110 by the cooperation of the sliding groove and the sliding table, thereby realizing the adjustable distance between the mounting portion 140 and the mounting seat 110, and the structure is simple and easy to operate.

[0071] In addition, the driving mode of the mounting portion 140 is various, in an embodiment, the mounting portion 140 can be manually driven, when manually driven, the mounting portion 140 and the mounting arm 112 are further provided with a locking structure, when the mounting portion 140 is adjusted to the position, the mounting portion 140 is locked and fixed on the mounting arm 112 through the locking structure, to avoid that the mounting portion 140 continues to move after the position of the liquid cooling radiator 130 is adjusted. Since the locking structure for realizing the locking belongs to the prior art, the present application does not make specific description here.

[0072] In another embodiment, the mounting portion 140 can also be driven to move by a linear motor, an electric push rod or a hydraulic cylinder, to realize mechanization, simple operation and intelligentization, specifically, the present application is not limited.

[0074] In the above embodiment, since the liquid cooling radiator 130 is clamped between the wind cooling fin 150 and the cooling fan 160, the cooling fan 160 blows the air through the liquid cooling radiator 130, the cooling capacity radiated by the liquid cooling radiator 130 realizes the cooling of the air blown by the fan, which can effectively reduce the ambient temperature around the wind cooling fin 150, effectively cool the electric control cabinet 120, and ensure the reliable operation of the internal devices of the electric control cabinet 120.

[0075] It should be noted that, in order to ensure the air circulation, the liquid cooling radiator 130 is mounted on the two mounting arms 112 provided on the mounting seat 110 through the mounting portion 140, so that the liquid cooling radiator 130 as a whole does not directly contact the electric control cabinet 120 and the wind cooling fin 150, to provide space for the circulation of air, and the cooling effect is good.

[0076] The type of the liquid cooling radiator 130 is various, in the embodiment of the present application, the liquid cooling radiator 130 can include a micro-channel heat exchanger and / or a finned tube heat exchanger, that is, in an embodiment, the liquid cooling radiator 130 can be a micro-channel heat exchanger, in another embodiment, the liquid cooling radiator 130 can include a finned tube heat exchanger, and in still another embodiment, the liquid cooling radiator 130 can include a micro-channel heat exchanger and a finned tube heat exchanger.
