In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] like Figure 1As shown, this embodiment provides a heat dissipation device, which is mainly used to cool and dissipate heat for a vacuum pump. Of course, the heat dissipation device can also be used in other devices that require heat dissipation. Specifically, the heat dissipation device includes a first heat dissipation component 1 and a second heat dissipation component 2, the first heat dissipation component 1 includes a box body 11, and the box body 11 contains a coolant, the second heat dissipation component 2 includes a cold source and a liquid cooling plate 21, the inlet and outlet of the liquid cooling plate 21 are both connected to the cold source, the cold source is used to provide coolant to the liquid cooling plate 21, the liquid cooling plate 21 is installed in the box body 11, and the heat dissipation element 100 to be cooled is fixed on the liquid cooling plate 21, and the coolant in the liquid cooling plate 21 circulates so that the liquid cooling plate 21 can take away the heat of the heat dissipation element 100 to cool and dissipate heat for the heat dissipation element 100. At the same time, the liquid cooling plate 21 and part of the heat dissipation element 100 are in contact with the cooling liquid in the box 11, and the cooling liquid in the box 11 can further dissipate heat for the heat dissipation element 100, so that the heat dissipation device performs double heat dissipation for the heat dissipation element 100, thereby improving the heat dissipation effect, avoiding excessive temperature rise of the heat dissipation element 100, and improving the protection of the heat dissipation element 100. In addition, the liquid cooling plate 21 can also cool the cooling liquid in the box 11, and the cooling liquid in the box 11 can always have a good cooling and heat dissipation effect without replacing the cooling liquid in the box 11.

[0036] In this embodiment, handles are designed on both sides of the box body 11. The handles are grooves that penetrate the side walls of the box body 11, which facilitate operators to move the entire box body 11 and improve the flexibility of use of the above-mentioned heat dissipation device.

[0037] Specifically, the performance parameter requirements of the cold source are as follows: cooling capacity 1000W, temperature range 10-30 degrees Celsius, temperature control accuracy ±0.5 degrees Celsius, flow rate>10L / min, liquid outlet pressure>250Kpa, liquid storage volume not less than 20L, the cold source needs to continuously output 20°C coolant to dissipate heat for the heat element 100 to be cooled and the coolant in the box 11. Optionally, the operator can adaptively select cold sources with different performance parameters to provide coolant according to the heat dissipation requirements of the heat element 100 to be cooled, which is not specifically limited here.

[0038] In this embodiment, the motor 200 drives the heat dissipation element 100 to operate. In order to prevent the coolant contained in the box 11 from entering the motor 200 and causing a short circuit, a liquid level sensor 12 is installed in the box 11 to monitor the liquid level of the coolant in the box 11 to prevent the liquid level of the coolant in the box 11 from being too high, so as to ensure the safety of the motor 200. At the same time, when the liquid level of the coolant in the box 11 is detected to be too low, the staff can be reminded to add coolant to the box 11 in time to ensure that the heat dissipation element 100 has sufficient contact area with the coolant, thereby improving the heat dissipation effect of the heat dissipation element 100.

[0039] Specifically, Figure 1-2As shown, the liquid cooling plate 21 includes a bottom plate 211 and a heat dissipation pipe 212, the bottom plate 211 is provided with a flow channel groove, the heat dissipation pipe 212 is snap-fitted and installed in the flow channel groove, the inlet and outlet of the heat dissipation pipe 212 are both connected to the cold source, the bottom plate 211 is arranged in the box 11, the heat dissipation element 100 is fixed on the bottom plate 211, and the cold source continuously provides flowing coolant to the heat dissipation pipe 212, so that the heat dissipation pipe 212 can take away the heat of the heat dissipation element 100 on the bottom plate 211 and the coolant contained in the box 11. By designing the liquid cooling plate 21 as a split structure, the disassembly, assembly and replacement of the heat dissipation pipe 212 is facilitated, and the processing difficulty of the bottom plate 211 is reduced, saving costs. Optionally, the connection method between the heat dissipation element 100 and the bottom plate 211 includes but is not limited to screws, screws or welding, etc., which are not specifically limited here.

Preferably, the adapter tube 22 is a flexible tube, which can be adaptively bent and flexibly arranged according to the relative position of the heat dissipation pipe 212 and the cold source, and the connection between the heat dissipation pipe 212 or the cold source has good sealing performance, so that the coolant is not easy to leak.

One adapter tube 22 is connected to the water outlet of the cold source through one through-cabin component 23, and the other adapter tube 22 is connected to the water return end of the cold source through another through-cabin component 23. Through the above arrangement, the cold source and the heat dissipation pipe 212 can pass through the side wall of the box body 11 to communicate with each other, thereby avoiding leakage of the coolant in the box body 11. At the same time, the heat dissipation device has a simple structure, and various pipelines are arranged neatly to avoid entanglement with each other. In addition, the cold source and the heat dissipation pipe 212 can be quickly connected, which is convenient for installation or disassembly. In other embodiments, the adapter tube 22 can also be directly connected to the water outlet or water return end of the cold source from the top of the box body 11, thereby reducing production costs.

One end of the quick-plug connector 231 and the straight pipe fitting 232 are both threadedly connected to the same corresponding threaded hole, and are connected through the threaded hole, thereby facilitating the installation or disassembly of the through-cabin assembly 23, while ensuring the sealing of the box body 11 and preventing the coolant from leaking from the threaded hole; the other end of the quick-plug connector 231 is connected to the water outlet or return end of the corresponding cold source, and the other end of the straight pipe fitting 232 is connected to a corresponding adapter tube 22, which is convenient for replacing the cold source or the adapter tube 22, thereby improving the flexibility of the heat dissipation device provided in this embodiment.

The fans can be flexibly arranged on the side wall of the box 11 or outside the box 11 according to the use requirements, which is not specifically limited here.

[0045] In this embodiment, the heat dissipation device further includes a temperature monitoring component, which includes a temperature sensor 3, which is arranged on the surface of the heat dissipation component 100 and can detect the surface temperature of the heat dissipation component 100. Furthermore, the temperature monitoring component further includes a temperature alarm, which is connected to the temperature sensor 3 in communication so as to transmit the temperature value detected by the temperature sensor 3 to the temperature alarm by wire or wireless means. The temperature alarm can receive the signal sent by the temperature sensor 3 and send an overheating alarm when the surface temperature of the heat dissipation component 100 exceeds the set value, so as to remind the staff to intervene in time. The above-mentioned set value needs to be adjusted according to the actual working conditions, and is not specifically limited here.
