The above scheme still has the following disadvantages: when the switch is working, the heat dissipation device needs to keep the refrigerant flowing, and the fan also needs to keep running at high power, which causes a waste of resources.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a liquid-cooled and air-cooled hybrid heat dissipation device for a switch, comprising an upper heat dissipation box and a lower heat dissipation box, the upper heat dissipation box and the lower heat dissipation box are respectively fixed on the top surface and the bottom surface of the switch, the right sides of the upper heat dissipation box and the lower heat dissipation box are respectively connected and fixed with a plurality of water inlet pipes, and the plurality of water inlet pipes, wherein every two of the water inlet pipes form a group, and a water pump is connected and fixed between each group of the water inlet pipes, and the left sides of the upper heat dissipation box and the lower heat dissipation box are connected and fixed with a water outlet pipe, and three four-way pipes are arranged inside the upper heat dissipation box and the lower heat dissipation box, and the two ends of the water inlet pipe and the water outlet pipe that are close to each other are connected and fixed through the four-way pipe, and the three four-way pipes are connected and fixed with connecting pipes, and two air outlets are respectively provided on the left and right sides of the upper heat dissipation box and the lower heat dissipation box, and a fan is fixed inside the air outlet, and the upper heat dissipation box, the lower heat dissipation box, the water inlet pipe, the water outlet pipe, the four-way pipe, and the connecting pipe are all made of aluminum.
[0007] Preferably, the upper heat sink and the lower heat sink are respectively provided with pipe openings on their rear sides, and in the upper heat sink, a liquid level sensor is fixed to one end of the four-way pipe close to the pipe opening, and in the lower heat sink, a temperature sensor is fixed to one end of the four-way pipe close to the pipe opening, and a PLC controller is fixed to the top surface of the upper heat sink, and the water pump, the fan, the liquid level sensor and the temperature sensor are all electrically connected to the PLC controller.

[0011] Preferably, the outer wall fixed sleeve of the cooling water replenishment pipe is provided with thermal insulation cotton.
[0012] Compared with the prior art, a liquid-cooled and air-cooled hybrid heat dissipation device for a switch using the above technical solution has the following beneficial effects:
[0013] 1. During use, when the switch body is working, the staff starts the fan and opens the first solenoid valve and the second solenoid valve, and adds cooling water through the cooling water supply pipe. When cooling water is discharged from the drain pipe, the first solenoid valve and the second solenoid valve are closed. After the cooling water passes through the internal four-way pipe and connecting pipe of the upper heat sink, it flows to the lower heat sink through the outlet pipe on the left. When the cooling water reaches the lower heat sink, it flows to the right water inlet pipe through the four-way pipe and connecting pipe inside the lower heat sink. After flowing into the water inlet pipe, it flows into the upper heat sink through the water pump. While the cooling water is flowing, the fan fixed on the inner wall of the air outlet starts to blow air into the upper heat sink and the lower heat sink. The fans on both sides of the upper heat sink and the lower heat sink are in the same direction. When the cooling water flows in the aluminum pipe through the water pump, the switch is cooled down. The cooling water absorbs the heat released by the switch and the temperature rises. At this time, the fan sucks and blows air, and further reduces the surface temperature of the switch, and also reduces the temperature of the cooling water in the aluminum pipe, so that it can be recycled and reduce resource waste.
[0014] 2. During use, the liquid level sensor and temperature sensor can detect the liquid level and temperature in the aluminum pipe. After the staff sets the warning temperature and liquid level, when the temperature in the aluminum pipe reaches the warning value, the temperature sensor sends a signal to the PLC controller, and the PLC controller sends a command to the first solenoid valve, so that the first solenoid valve opens the valve to add cooling water. When the temperature is lower than the warning temperature, the first solenoid valve automatically closes the valve to stop adding water. The whole process is more automated, saving time and effort, and avoiding damage to the internal components of the switch due to excessive temperature. At the same time, the thermal insulation cotton wrapped outside the cooling water supply pipe can maintain the original temperature of the cooling water during the cooling water supply pipe replenishment process;
[0015] 3. During use, when the liquid level in the aluminum pipe reaches the warning value, the liquid level sensor sends a signal to the PLC controller, and the PLC controller sends a command to the second solenoid valve, causing the second solenoid valve to open the valve, and the water in the aluminum pipe is drained out through the drain pipe, and the second solenoid valve is closed. This can keep the liquid level in the aluminum pipe normal and prevent excessive water replenishment. The whole process is automated, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0023] like Figure 1-Figure 5 As shown, a liquid-cooled and air-cooled hybrid heat dissipation device for a switch comprises an upper heat dissipation box 1 and a lower heat dissipation box 2, wherein the upper heat dissipation box 1 and the lower heat dissipation box 2 are respectively fixed on the top surface and the bottom surface of the switch, and a plurality of water inlet pipes 3 are connected and fixed to the right sides of the upper heat dissipation box 1 and the lower heat dissipation box 2, wherein every two water inlet pipes 3 form a group, and a water pump 4 is connected and fixed between each group of water inlet pipes 3, and a water outlet pipe 5 is connected and fixed to the left sides of the upper heat dissipation box 1 and the lower heat dissipation box 2, and three four-way pipes 6 are arranged inside the upper heat dissipation box 1 and the lower heat dissipation box 2, and the two ends of the water inlet pipe 3 and the water outlet pipe 5 close to each other are connected and fixed through the four-way pipe 6, and the three four-way pipes 6 are connected and fixed with connecting pipes 7, and two air vents 8 are respectively provided on the left and right sides of the upper heat dissipation box 1 and the lower heat dissipation box 2, and a fan 9 is fixed inside the air vent 8, and the upper heat dissipation box 1, the lower heat dissipation box 2, the water inlet pipe 3, the water outlet pipe 5, the four-way pipe 6, and the connecting pipe 7 are all made of aluminum.
[0024] When the switch is working, the staff starts the fan 9 and opens the first solenoid valve 15 and the second solenoid valve 17, and adds cooling water through the cooling water supply pipe 14. When cooling water is discharged from the drain pipe 16, the first solenoid valve 15 and the second solenoid valve 17 are closed. The cooling water flows through the four-way pipe 6 and the connecting pipe 7 inside the upper heat sink 1, and then flows to the lower heat sink 2 through the outlet pipe 5 on the left. When the cooling water reaches the inside of the lower heat sink 2, it flows to the right water inlet pipe 3 through the four-way pipe 6 and the connecting pipe 7 inside the lower heat sink 2. After flowing into the water inlet pipe 3, it is pumped out through the water pump. 4 and then flows into the upper heat sink 1. While the cooling water flows, the fan 9 fixed on the inner wall of the air outlet 8 starts to blow air into the upper heat sink 1 and the lower heat sink 2. The fans on both sides of the upper heat sink 1 and the lower heat sink 2 rotate in the same direction. When the cooling water flows in the aluminum pipe through the water pump 4, the switch is cooled down. The cooling water absorbs the heat released by the switch and its temperature rises. At this time, the fan 9 sucks and blows air, further reducing the surface temperature of the switch and the temperature of the cooling water in the aluminum pipe, so that it can be recycled and reduced resource waste.
[0025] like Figure 1-Figure 3 , Figure 5 As shown, a cooling water supply pipe 14 is connected and fixed to the front side of the upper heat sink 1, a first solenoid valve 15 is arranged at the top end of the cooling water supply pipe 14, a thermal insulation cotton 18 is fixedly sleeved on the outer wall of the cooling water supply pipe 14, pipe openings 10 are respectively opened on the rear sides of the upper heat sink 1 and the lower heat sink 2, a liquid level sensor 11 is fixed to one end of the four-way pipe 6 close to the pipe opening 10 in the upper heat sink 1, a temperature sensor 12 is fixed to one end of the four-way pipe 6 close to the pipe opening 10 in the lower heat sink 2, a PLC controller 13 is fixed to the top surface of the upper heat sink 1, and the water pump 4, the fan 9, the liquid level sensor 11, the temperature sensor 12 and the first solenoid valve 15 are all electrically connected to the PLC controller 13.
[0026] During use, the liquid level sensor 11 and the temperature sensor 12 can detect the liquid level and temperature in the aluminum pipe. After the staff sets the warning temperature and liquid level, when the temperature in the aluminum pipe reaches the warning value, the temperature sensor 12 sends a signal to the PLC controller 13, and the PLC controller 13 sends an instruction to the first solenoid valve 15, so that the first solenoid valve 15 opens the valve to replenish cooling water. When the temperature is lower than the warning temperature, the first solenoid valve 15 automatically closes the valve to stop adding water. The whole process is more automated and easy to operate, avoiding damage to the internal components of the switch due to excessive temperature. At the same time, the thermal insulation cotton 18 wrapped around the outside of the cooling water make-up pipe 14 can maintain the original temperature of the cooling water during the water replenishment process of the cooling water make-up pipe 14.
[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a drain pipe 16 is connected and fixed to the front side of the lower heat dissipation box 2, a second solenoid valve 17 is provided at the front end of the drain pipe 16, the second solenoid valve 17 is electrically connected to the PLC controller 13, and a dustproof net 19 is fixed inside the air outlet 8, and the dustproof net 19 corresponds to the fan 9.
[0028] During use, when the liquid level in the aluminum pipe reaches the warning value, the liquid level sensor 11 sends a signal to the PLC controller 13, and the PLC controller 13 sends an instruction to the second solenoid valve 17, so that the second solenoid valve 17 opens the valve. After the water in the aluminum pipe is drained out through the drain pipe 16, the second solenoid valve 17 can be closed. In this way, the liquid level in the aluminum pipe can be kept normal to prevent excessive water replenishment. The whole process is automated, saving time and effort.
