[0002] Vacuum coating machines mainly refer to a class of equipment that needs to perform coating under a relatively high vacuum. When a vacuum coating machine is working, a large amount of heat will be generated. If the heat cannot be dissipated in time, it is easy to cause heat accumulation, which will affect the coating effect and the safety of the equipment. The existing heat dissipation methods include liquid cooling, air cooling, conductor cooling, and semiconductor cooling, etc. The existing heat dissipation structure of vacuum coating machines is relatively single, mainly using liquid nitrogen or spraying cooling water. The cost of liquid nitrogen is relatively high, and spraying cooling water is easy to cause the coated material to be contaminated and is also easy to damage the vacuum coating machine. Content of the Utility Model
[0003] The purpose of the utility model is to provide a heat dissipation structure of a vacuum coating machine with multiple cooling structures to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A heat dissipation structure of a vacuum coating machine with multiple cooling structures, including a vacuum coating machine main body. A heat conduction ring is sleeved in the middle of the vacuum coating machine main body. A plurality of heat dissipation plates are fixedly connected to the side end of the heat conduction ring. Wires are fixedly connected to both sides of the heat dissipation plate. A water delivery ring is arranged outside the heat conduction ring. Heat dissipation parts are attached to both sides of the heat dissipation plate. One end of the heat dissipation part is fixedly connected to the water delivery ring, and the other end of the heat dissipation part is fixedly connected to a drain pipe. A sliding channel is arranged in the middle of the heat dissipation plate. A piston head is slidably connected inside the sliding channel. A connecting column is fixedly connected to the top end of the piston head. A return spring is fixedly connected between the piston head and the inner wall of the sliding channel. The return spring is wound around the connecting column. A support plate is fixedly connected to the outer side wall of the heat conduction ring. The support plate is in an L-shaped structure. A clamping buckle is fixedly connected to the inner wall of the water delivery ring. The clamping buckle and the support plate are clamped with each other.
[0005] Preferably, there is a gap between the piston head and the heat conduction ring, and there is a gas that is easily expanded by heat in the gap between the piston head and the heat conduction ring.
[0006] Preferably, a communication contact is fixedly connected to the top end of the connecting column. Two conductive contacts are fixedly connected inside the heat dissipation plate.

[0007] Preferably, a clamping groove is arranged at the lower end of the heat dissipation plate, and the upper end of the water delivery ring is clamped in the clamping groove.
[0008] Preferably, a water channel is formed between the heat sink and the heat dissipation plate. The water delivery ring is communicated with the water channel, and the drain pipe is communicated with the water channel.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The heat conduction ring conducts the heat generated by the vacuum coating machine main body, and then the heat is preliminarily dissipated through the heat dissipation plate. At this time, the gas in the sliding channel expands due to heat. When a large amount of heat accumulates in the vacuum coating machine main body, the piston head is pushed to move, so that the connecting contact is in contact with the two conductive contacts, and the circuit is connected, thereby supplying water to the water delivery ring to perform liquid cooling and heat dissipation on the heat dissipation plate, greatly increasing the heat dissipation effect, and at the same time avoiding unnecessary waste. Multiple cooling structures are used to dissipate heat from the vacuum coating machine main body, and liquid cooling is started according to the amount of heat accumulation for heat dissipation, which is more economical.

[0015] Please refer to Figure 1-2, the present utility model provides a technical solution: a heat dissipation structure of a vacuum coating machine with multiple cooling structures, including a vacuum coating machine main body 1. A heat conduction ring 2 is sleeved in the middle of the vacuum coating machine main body 1. A plurality of heat dissipation plates 6 are fixedly connected to the side end of the heat conduction ring 2. Wires are fixedly connected to both sides of the heat dissipation plate 6. A water delivery ring 3 is arranged outside the heat conduction ring 2. Heat dissipation elements 13 are attached to both sides of the heat dissipation plate 6. One end of the heat dissipation element 13 is fixedly connected to the water delivery ring 3, and the other end of the heat dissipation element 13 is fixedly connected to a drain pipe 16. A sliding channel 7 is arranged in the middle of the heat dissipation plate 6. A piston head 8 is slidably connected inside the sliding channel 7. A connecting column 9 is fixedly connected to the top end of the piston head 8. A return spring 10 is fixedly connected between the piston head 8 and the inner wall of the sliding channel 7.

The support plate 4 is in an L-shaped structure. A clamping buckle 5 is fixedly connected to the inner wall of the water delivery ring 3. The clamping buckle 5 and the support plate 4 are clamped with each other. The heat conduction ring 2 conducts the heat of the vacuum coating machine main body 1. First, heat dissipation treatment is carried out through the heat dissipation plate 6. When there is more heat and the heat dissipation plate 6 cannot dissipate heat in time, the water delivery ring 3 is supplied with water, thereby performing liquid cooling heat dissipation on the heat dissipation plate 6 and increasing the heat dissipation efficiency.
[0016] There is a gap between the piston head 8 and the heat conduction ring 2. There is a gas that is easily expanded by heat in the gap between the piston head 8 and the heat conduction ring 2. A communicating contact 12 is fixedly connected to the top end of the connecting column 9. Two conductive contacts 11 are fixedly connected inside the heat dissipation plate 6. The two conductive contacts 11 are connected to the two poles of the power supply. There is a gap between the two conductive contacts 11. The gas that is easily expanded by heat between the piston head 8 and the heat conduction ring 2 expands when heated, thereby pushing the piston head 8 and the connecting column 9 to move, so as to abut the communicating contact 12 against the conductive contact 11, and energize the two conductive contacts 11, thereby supplying water to the water delivery ring 3.
[0017] A clamping groove is arranged at the lower end of the heat dissipation plate 6. The upper end of the water delivery ring 3 is clamped in the clamping groove to fixedly support the heat dissipation plate 6. At the same time, the water delivery ring 3 also dissipates heat from the heat dissipation plate 6, increasing the heat dissipation efficiency.
[0018] A water flow channel is formed between the heat dissipation element 13 and the heat dissipation plate 6. The water delivery ring 3 is communicated with the water flow channel. The drain pipe 16 is communicated with the water flow channel. A convex portion 14 is arranged in the middle of the heat dissipation element 13. Heat conduction protrusions 15 are fixedly connected to both sides of the heat dissipation plate 6. The heat conduction protrusions 15 are located in the middle of the convex portion 14. The heat conduction protrusions 15 can increase the contact area with the cooling water, thereby increasing the heat dissipation effect.
