Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0029] The present application embodiment provides an electric control box, such as Figures 1 to 8 As shown, the electric control box includes a box body 100, a mounting plate 200, a heat exchanger 300 and a refrigerant pipe 400. A containing space is formed in the box body 100, and the mounting plate 200 is arranged in the containing space; the periphery of the mounting plate 200 is sealed and connected to the inner surface of the box body 100 to separate the containing space into a first chamber 101 and a second chamber 102. The surface of the mounting plate 200 facing the second chamber 102 is suitable for installing a heating element (such as a controller), that is, the heating element is installed on the mounting plate 200 and is located in the second chamber 102; the heat exchanger 300 and the refrigerant pipe 400 are both arranged in the first chamber 101, and the refrigerant pipe 400 is connected to the heat exchanger 300 and the end of the refrigerant pipe 400 passes out of the box body 100. Optionally, the heat exchanger 300 can be a microchannel heat exchanger.

[0030] The electric control box provided in the embodiment of the present application is provided with a mounting plate 200 in the accommodating space of the box body 100, so that the periphery of the mounting plate 200 is sealed and connected to the inner surface of the box body 100, so as to divide the accommodating space of the box body 100 into a first chamber 101 and a second chamber 102. A heat exchanger 300 and a refrigerant pipe 400 are provided in the first chamber 101. The heat exchanger 300 uses the refrigerant to exchange heat with the air in the first chamber 101 to cool the air in the first chamber 101, thereby achieving the effect of heat dissipation for the electric control box. Since the periphery of the mounting plate 200 is sealed and connected to the inner surface of the box body 100, the low-temperature air in the first chamber 101 will not overflow from the periphery of the mounting plate 200 to the second chamber 102 to cause condensation on the heating element (such as a controller), thereby avoiding condensation from causing failure of the heating element.

[0031] In some embodiments of the present application, a connecting plate is provided around the periphery of the mounting plate 200, and the connecting plate is sealed and connected to the inner surface of the box body 100 (i.e., the periphery of the mounting plate 200 is sealed and connected to the inner surface of the box body 100 via the connecting plate), so as to separate the accommodating space into the first chamber 101 and the second chamber 102. Of course, the periphery of the mounting plate 200 can also be directly sealed and connected to the inner surface of the box body 100, without the need for connection via the connecting plate.

[0032] Optionally, the connecting plate includes an upper connecting plate 210, a lower connecting plate 220, a left connecting plate 230 and a right connecting plate 240, which are sequentially connected along the periphery of the mounting plate 200; wherein the upper connecting plate 210 is arranged opposite to the lower connecting plate 220, and the left connecting plate 230 is arranged opposite to the right connecting plate 240. The upper connecting plate 210, the lower connecting plate 220, the left connecting plate 230 and the right connecting plate 240 surround the refrigerant pipe 400 and the heat exchanger 300 from the upper, lower, left and right sides of the mounting plate 200, so that the low-temperature air cooled by the refrigerant in the heat exchanger 300 will not overflow from the upper, lower, left and right sides of the mounting plate 200 to the second chamber 102 to cause condensation on the heating element (such as the controller) in the second chamber 102, thereby preventing the condensation from causing failure to the heating element.

[0033] Optionally, the box body 100 includes a top plate 110, a bottom plate 120, a front panel 130, a rear panel 140, a left side plate 150, and a right side plate 160, which are enclosed to form a receiving space; wherein the top plate 110 is arranged opposite to the bottom plate 120, the front panel 130 is arranged opposite to the rear panel 140, the left side plate 150 is arranged opposite to the right side plate 160, the mounting plate 200 is located between the front panel 130 and the rear panel 140, and the connecting plate is sealed and connected to the inner surface of the rear panel 140, so that the connecting plate, the mounting plate 200 and the inner surface of the rear panel 140 are enclosed to form a first chamber 101. In this way, the electric control box can be designed to be fully sealed while ensuring the heat dissipation of the control box, thereby greatly enhancing the waterproof performance of the electric control box.

[0034] In some embodiments of the present application, the box body 100 is provided with a first through hole 103 for the refrigerant tube 400 to pass through, and the end of the refrigerant tube 400 passes through the first through hole 103 to the outside of the box body 100. Specifically, one refrigerant tube 400 corresponds to two first through holes 103, one end of the refrigerant tube 400 passes through one of the through holes, and the other end of the refrigerant tube 400 passes through the other through hole. Optionally, the first through hole 103 can be set on the bottom plate 120 of the box body 100.

[0035] Optionally, a first waterproof seal is provided at the first through hole 103, and the first waterproof seal is configured to seal the gap between the first through hole 103 and the refrigerant pipe 400 passing through the first through hole 103. The first waterproof seal can effectively prevent water from entering the first through hole 103, thereby improving the waterproofness of the electric control box, and at the same time can reduce the loss of low-temperature air brought to the inside of the electric control box by using the refrigerant heat exchange through the first through hole 103.

[0036] Optionally, the first waterproof seal is a first waterproof flexible member, and the first waterproof flexible member is provided with a wire-passing gap for the refrigerant tube 400 to pass through. In this way, it is ensured that the refrigerant tube 400 can pass through the first waterproof flexible member and extend outside the box body 100 to achieve the connection between the refrigerant tube 400 and the external pipeline; and it is convenient to use the elastic deformation ability of the first waterproof flexible member to seal the first through hole 103 to prevent water from entering the first through hole 103. Exemplarily, the first waterproof flexible member can be a flexible sleeve.

[0037] In some embodiments of the present application, the box body 100 is provided with a second via hole 104, which is suitable for allowing a cable to pass through. The number of the second via holes 104 can be one or more, which can be set according to actual needs. Optionally, the second via hole 104 can be set on the bottom plate 120 of the box body 100.

[0038] Optionally, a second waterproof seal 105 is provided at the second via hole 104, and the second waterproof seal 105 is configured to seal the gap between the second via hole 104 and the cable passing through the second via hole 104. The second waterproof seal 105 can effectively prevent water from entering the second via hole 104, thereby improving the waterproofness of the electric control box, and at the same time can reduce the loss of low-temperature air brought to the inside of the electric control box through the second via hole 104 by using the refrigerant heat exchange.

[0039] Optionally, the second waterproof seal 105 is a second waterproof flexible member, and the second waterproof flexible member is provided with a wire-passing gap for the cable to pass through. In this way, it is ensured that the refrigerant tube 400 can pass through the second waterproof flexible member and extend out of the box body 100 to achieve the connection between the refrigerant tube 400 and the external pipeline; and it is convenient to use the elastic deformation ability of the second waterproof flexible member to seal the second via hole 104 to prevent water from entering the second via hole 104. Exemplarily, the second waterproof flexible member can be a flexible sleeve.

[0040] In some embodiments of the present application, Figure 1 to Figure 4 and Figure 8 As shown, a ventilation hole 201 is provided at the lower end of the mounting plate 200, and a heating element is arranged at the upper end of the mounting plate 200. The ventilation hole 201 can allow the air in the first chamber 101 to transfer heat with the air in the second chamber 102, thereby improving the heat dissipation effect of the electric control box; and because the ventilation hole 201 is arranged at the lower end of the mounting plate 200 and the heating element is arranged at the upper end of the mounting plate 200, the condensation generated by the heat exchange of cold and hot air will only be generated below the heating element, and no condensation will be generated above the heating element and drip on the heating element to cause a malfunction. Specifically, when the box body 100 includes a top plate 110 and a bottom plate 120, the ventilation hole 201 is arranged at one end of the mounting plate 200 close to the bottom plate 120, and the heating element is arranged at one end of the mounting plate 200 close to the top plate 110.

[0041] Optionally, the number and size of the ventilation holes 201 can be set according to the actual heat generation of the heating element in the electrical control box and the heat exchange capacity of the refrigerant pipe 400, so that the working environment temperature of the heating element will not be too high to affect the life of the heating element, nor too low to cause condensation on the surface of the heating element and cause malfunction.

[0042] Further, such as Figure 1 to Figure 4 As shown, the electric control box further includes a fan 500, which is disposed on the mounting plate 200 and located in the second chamber 102. When the fan is running, the air in the electric control box can be disturbed to improve the air heat transfer efficiency between the first chamber 101 and the second chamber 102, so as to cool the heating element more quickly and improve the heat dissipation effect of the electric control box. Specifically, when the box body 100 includes the front panel 130, the fan is disposed between the mounting plate 200 and the front panel 130 and fixed on the mounting plate 200.
