[0022] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0023] See also Figure 1-Figure 4In order to solve the problems in the prior art, the present invention provides an air conditioner electric control box heat dissipation device 1, which includes an electric control box body 11, a support frame 12 and a heat dissipation component 13. The heat dissipation component 13 is installed inside the electric control box body 11 through the support frame 12. The support frame 12 includes a bent portion 121 and a connecting portion 122. The bent portion 121 is located on the left and right sides of the connecting portion 122. The bent portion 121 is attached to the inner wall of the electric control box body 11 and is connected to the electric control box body 11. The connecting portion 122 is connected to the inner wall of the electric control box body 11. A heat dissipation space is formed, and a heat dissipation hole 111 is opened at a position corresponding to the heat dissipation space on the electrical control box body 11. The heat dissipation assembly 13 includes a water tank 131, a first water pipe joint 132, a second water pipe joint 133 and a connecting pipe. The water tank 131 is detachably connected to the surface of the connecting portion 122 away from the heat dissipation space. The interior of the water tank 131 is filled with coolant. The first water pipe joint 132 and the second water pipe joint 133 are respectively installed on the left and right sides of the water tank 131. The connecting pipe is connected to the first water pipe joint 132 and is connected to the second water pipe joint 133 after being wrapped around the electrical control box body 11.

[0024] By installing the support frame 12 inside the electric control box body 11, so that the support frame 12 provides support for the water tank 131, by providing bending parts 121 at the left and right ends of the support frame 12, and forming a heat dissipation space between the connecting part 122 and the inner wall of the electric control box body 11, so that the support frame 12 can absorb the heat of the water tank 131 and transfer the heat to the heat dissipation space, by opening a heat dissipation hole 111 at a position corresponding to the heat dissipation space on the electric control box body 11, the heat in the heat dissipation space is discharged from the heat dissipation hole 111, thereby achieving the heat dissipation effect on the air conditioner electric control box, avoiding the heat generated by the electronic components in the air conditioner electric control box during operation and failing to be dissipated in time, which affects the life of the electronic components and the stability of the air conditioner operation.

[0025] In the above embodiment, a first water pipe joint 132 and a second water pipe joint 133 are respectively installed on the left and right sides of the water tank 131, and a connecting pipe is connected to the first water pipe joint 132. The connecting pipe is then looped around the inside of the electric control box body 11 and connected to the second water pipe joint 133. As a result, the coolant in the water tank 131 enters the connecting pipe from the first water pipe joint 132 and then flows back into the water tank 131 from the second water pipe joint 133. Since the connecting pipe loops around the inside of the electric control box body 11, the coolant absorbs heat from various parts of the electric control box as it passes through the connecting pipe, thereby achieving a cooling effect on the electric control box. After the heat-absorbing coolant flows back to the water tank 131, the support frame 12 absorbs the heat of the water tank 131, thereby achieving a heat dissipation effect on the water tank 131. The heat absorbed by the support frame 12 passes through the heat dissipation space and is discharged from the heat dissipation holes 111, thereby achieving a heat dissipation effect on the electric control box and improving the stability of the air-conditioning system during operation.

[0026] In the above embodiment, a water pump is provided in the water tank 131. The water pump is located at the bottom of the water tank 131 and is connected to the first water pipe joint 132. The coolant in the water tank 131 is extracted by the water pump, and the coolant passes through the first water pipe joint 132, the connecting pipe and the second water pipe joint 133 and then flows back into the water tank 131, thereby achieving the circulation of the coolant and improving the heat dissipation effect inside the electronic control box.

[0027] See also Figure 3 In an embodiment of the present utility model, the first water pipe joint 132 includes a main water pipe 1321 and at least two branch water pipes 1322 that are interconnected. The main water pipe 1321 is installed on the water tank 131, and the branch water pipes 1322 are connected to the water tank 131 through the main water pipe 1321. The structure of the second water pipe joint is the same as that of the first water pipe joint 132, and the number of connecting pipes is the same as the number of branch water pipes 1322, so that at least two connecting pipes can be connected between the first water pipe joint 132 and the second water pipe joint 133, and the two ends of each connecting pipe are respectively connected to the branch water pipes 1322 on the first water pipe joint 132 and the second water pipe joint 133, so that heat is dissipated at various positions inside the electric control box under the action of at least two connecting pipes, thereby improving the heat dissipation effect of the electric control box.

[0028] In an embodiment of the present invention, six water distribution pipes 1322 are arranged in an array along the height direction of the water tank 131, and the number of connecting pipes is set to 6, so that the heat dissipation effect inside the electric control box is further improved under the connection between the 6 connecting pipes and the 6 water distribution pipes 1322.

[0029] See also Figure 4 In an embodiment of the present invention, the heat dissipation assembly 13 further includes a fan 134, which is located in the heat dissipation space and fixedly connected to the connection portion 122. The fan 134 is aligned with the heat dissipation hole 111, so that when the fan 134 is working, the heat in the heat dissipation space and the support frame 12 is blown out from the heat dissipation hole 111, further improving the heat dissipation effect of the electric control box.

[0030] In an embodiment of the present invention, there are two fans 134 and two heat dissipation holes 111, and the two fans 134 are installed side by side on the left and right sides of the support frame 12 so that the two fans 134 work at the same time and blow the heat from the heat dissipation space and the support frame 12 out from the corresponding heat dissipation holes 111, thereby improving the heat dissipation effect of the electric control box.

[0031] In an embodiment of the present invention, the electric control box body 11 is installed inside the air conditioner outdoor unit, and the surface where the heat dissipation hole 111 is located is perpendicular to the installation surface of the electric control box body 11, so that the electric control box can smoothly dissipate heat through the heat dissipation hole 111, thereby avoiding the dissipated heat being blocked and affecting the heat dissipation effect of the electric control box.

[0032] In an embodiment of the present utility model, a protruding first buckle 1221 and a second buckle 1222 are provided on the surface of the connecting portion 122 close to the water tank 131, and a first plug block and a second plug block 1311 are respectively provided on the left and right sides of the water tank 131. The first plug block and the first plug block 1221 are plugged into each other, and the second plug block 1311 and the second plug block 1222 are plugged into each other, so that the water tank 131 is plugged into the support frame 12 under the action of the first plug block and the second plug block 1311. When the coolant in the water tank 131 needs to be replenished or replaced later, the water tank 131 can be conveniently removed directly from the support frame 12 without removing the support frame 12 from the electrical control box body 11.

[0033] See also Figure 4 In an embodiment of the present invention, a pressing plate 1223 is hinged on the first plug block, and a spring 1224 is provided between the pressing plate 1223 and the connecting portion 122. The spring 1224 presses the pressing plate 1223 against the surface of the first plug block. When the water tank 131 is disassembled, the pressing plate 1223 is pressed to rotate around the first buckle 1221 and compress the spring 1224 to separate the pressing plate 1223 from the surface of the first plug block. At this time, the water tank 131 can be rotated to separate the first plug block from the first buckle 1221, and then the water tank 131 can be pulled out, making it convenient to replenish and replace the coolant in the water tank 131.

[0034] In an embodiment of the present invention, the support frame 12 is an aluminum plate support frame 12, which is fixed to the inside of the electric control box body 11 by bolts, so as to absorb the heat of the water tank 131 under the action of the aluminum plate support frame 12, thereby improving the cooling effect of the support frame 12 on the water tank 131.
