Description

Technical Field

[0001] This application relates to the technical field of vacuum pumps, and in particular to an integrated air-cooled and water-cooled heat dissipation vacuum pump. Background Technology

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container to obtain a vacuum. A vacuum pump is a device that uses various methods to improve, generate, and maintain a vacuum in a closed space.

[0003] Vacuum pumps generate heat during operation, so cooling devices are often used. These devices are divided into two types: air-cooled and water-cooled. Air-cooled devices typically dissipate heat through heat sinks, using airflow or a combination of an auxiliary fan and heat sink to cool the vacuum pump. Water-cooled devices rely on the flow of coolant to cool the vacuum pump. Air-cooled devices have a simple structure but poor heat dissipation, while water-cooled devices have better heat dissipation but are more complex. Furthermore, the coolant itself has poor heat dissipation, making it easy for the coolant temperature to rise, thus failing to effectively cool the vacuum pump. Summary of the Invention

[0004] To improve the heat dissipation effect of the vacuum pump, this application provides an integrated air-cooled and water-cooled vacuum pump.

[0005] This application provides an integrated air-cooled and water-cooled vacuum pump, which adopts the following technical solution: A combined air-cooled and water-cooled vacuum pump includes a vacuum pump and a heat dissipation device mounted on the vacuum pump, wherein the heat dissipation device includes: The heat dissipation assembly consists of a heat dissipation base plate mounted on the vacuum pump and multiple heat dissipation fins spaced apart on the heat dissipation base plate, which work together to dissipate heat from the vacuum pump. A cooling plate is mounted on a heat dissipation base plate and has a cooling cavity inside with multiple insertion holes communicating with the cooling cavity. Multiple heat dissipation fins pass through the multiple insertion holes and extend to the outside of the cooling plate. The fluid delivery mechanism is used to input and output coolant into the cooling chamber.

[0006] By adopting the above technical solution, the heat dissipation base plate and multiple heat sinks work together to dissipate heat from the vacuum pump. At the same time, the liquid delivery mechanism is activated, allowing the coolant to flow in the cooling chamber. The coolant can dissipate heat from the heat sinks and heat dissipation base plate, and the air flow also dissipates heat from the heat sinks. Therefore, air cooling and water cooling work together to dissipate heat from the vacuum pump, thereby greatly improving the heat dissipation effect of the vacuum pump.

[0007] Meanwhile, the heat sink extends to the outside of the cooling plate, which greatly reduces the obstruction effect of the cooling plate on the air moving at the heat sink. This ensures both air cooling and water cooling effects on the heat sink, allowing the air cooling and water cooling effects to work together to better dissipate heat from the vacuum pump, further improving the heat dissipation effect of the vacuum pump.

[0008] Optionally, the heat dissipation assembly and the cooling plate are each provided with multiple units spaced vertically apart, and the infusion mechanism includes: A collection box is installed on the vacuum pump and communicates with the cooling chamber located at the lowest point, allowing the coolant in the cooling chamber to flow in. The pump body is mounted on the collection box and communicates with the inside of the collection box; An inlet pipe is installed on the pump body and communicates with the cooling chamber located at the highest point, allowing coolant to flow within the cooling chamber; the cooling chambers located on two adjacent cooling plates are connected by a connecting assembly.

[0009] By adopting the above technical solution, the pump body starts, allowing the coolant to flow into the cooling chamber through the inlet pipe. Then, the coolant flows into the lower cooling chamber through the connecting component and continues to flow. This process is repeated until the coolant flows into the collection box for circulation. This achieves coolant flow within multiple cooling plates, heat dissipation through multiple cooling plates, and after the coolant is transported to a higher position by the pump body, it flows under the action of gravity, thereby reducing the energy required for coolant flow, improving the heat dissipation effect of the vacuum pump, and saving energy consumption.

[0010] Optionally, the connectivity component includes: Two connecting pipes are installed on two adjacent cooling plates and communicate with the cooling cavity; The connecting hose is fitted at both ends and installed on two connecting pipes, both of which are positioned by clamps.

[0011] By adopting the above technical solution, multiple cooling plates are fixedly installed on multiple side walls of the vacuum pump. Then, the two ends of the connecting hose are sleeved on two connecting pipes, and the hose is positioned by two clamping parts. This connects the cooling chambers on two adjacent cooling plates, and also facilitates the disassembly of the cooling plates. This makes it easy to replace the cooling plates and connecting components, and improves the heat dissipation effect of the vacuum pump.

[0012] Optionally, the cooling plate is fixedly connected to the heat dissipation base plate by a fixing mechanism, thereby enabling the cooling cavity to communicate with the heat dissipation base plate.

[0013] By adopting the above technical solution, the contact area between the heat dissipation base plate and the vacuum pump is larger, thus improving the heat dissipation effect of the heat dissipation base plate and better cooling the vacuum pump. Therefore, by connecting the cooling chamber with the heat dissipation base plate, the heat dissipation effect of the heat dissipation base plate is further improved, thus further improving the cooling effect of the vacuum pump. At the same time, it is also convenient to connect the cooling plate, the heat dissipation base plate and multiple heat sinks together, realizing the installation and disassembly of multiple structures, further improving the cooling effect of the vacuum pump.

[0014] Optionally, the fixing mechanism includes: A retaining ring is installed on the side wall of the cooling plate; The mounting plate has multiple mounting holes spaced apart for the heat sink to pass through; Multiple fixing posts are set on the heat dissipation base plate, and the fixing ring is provided with multiple mounting holes that are inserted and matched with the fixing posts; Multiple fixing screws pass through the fixing plate and are threadedly connected to multiple fixing posts, pushing the fixing plate against the cooling plate and causing the fixing ring to press against the heat dissipation base plate for positioning; A sealing assembly is used to seal the gap between the cooling plate and the heat sink base plate, and the gap between the heat sink and the insertion hole.

[0015] By adopting the above technical solution, multiple heat sinks are passed through multiple insertion holes, and multiple fixing posts are inserted into multiple mounting holes to position the cooling plate. The fixing plate is then brought close to the cooling plate, allowing multiple heat sinks to pass through the fixing holes. The fixing plate is pushed against the cooling plate, and then a fixing screw is passed through the fixing plate and threadedly connected to the fixing post. The head of the fixing screw presses against the fixing plate, causing the fixing plate to press against the cooling plate and pushing the fixing ring against the heat dissipation base plate. This achieves a fixed connection between the heat sinks, the heat dissipation base plate, and the cooling plate, and also facilitates the disassembly and replacement of multiple structures, improving the heat dissipation effect of the vacuum pump. At the same time, the sealing component can seal the gaps, reducing the risk of cooling medium leakage and further improving the heat dissipation effect of the vacuum pump.

[0016] Meanwhile, the multiple fixing posts facilitate the positioning of the cooling plate. Since the heat dissipation base plate is designed for better heat dissipation, its thickness is relatively small. Therefore, the fixing posts enable threaded connection with the fixing screws. This not only ensures good heat dissipation of the heat dissipation base plate but also improves the convenience of installing the cooling plate, heat dissipation base plate, and multiple heat sinks, further enhancing the heat dissipation effect on the vacuum pump.

[0017] Optionally, the sealing assembly includes: The first sealing ring is snapped onto the fixing ring and pressed against the heat dissipation base plate for sealing; Multiple sealing rings are provided, corresponding to multiple insertion holes and fitted onto the heat sink. The fixing plate pushes the sealing rings to press against the gap between the heat sink and the insertion hole to seal.

[0018] By adopting the above technical solution, when the fixing ring presses against the heat dissipation base plate, the sealing ring one presses against the heat dissipation base plate for sealing, and multiple sealing rings two are fitted onto multiple heat dissipation fins. Multiple heat dissipation fins are passed through multiple fixing holes, so that the fixing plate presses against the cooling plate for positioning. At the same time, the fixing plate also pushes the sealing ring two to press against the gap between the heat dissipation fin and the insertion hole for sealing, thereby reducing the risk of coolant leakage in the cooling chamber and improving the heat dissipation effect of the vacuum pump.

[0019] Optionally, the heat sink is provided with an additional plate extending to the top of the heat sink. The additional plate cooperates with the heat sink to form a heat dissipation cavity that communicates with the cooling cavity. The additional plates located on two adjacent heat sinks cooperate with the cooling plate to form a ventilation channel for air supply.

[0020] By adopting the above technical solution, the coolant located in the cooling chamber can enter the heat dissipation chamber and dissipate heat on the heat sink, increasing the contact area between the coolant and the heat sink and greatly improving the heat dissipation effect of the heat sink. At the same time, the air can continue to dissipate heat on the heat sink and the auxiliary plate through the ventilation channel, thereby further improving the heat dissipation effect of the vacuum pump.

[0021] Optionally, the heat dissipation cavity and the cooling chamber cooperate to form a heat dissipation channel, and the liquid inlet pipe and the connecting component are connected to the heat dissipation channel so that the cooling medium enters from the lowest point of the heat dissipation channel and flows out from the highest point.

[0022] By adopting the above technical solution, the coolant can fill multiple heat dissipation channels, thereby further improving the heat dissipation effect on the vacuum pump.

[0023] Optionally, the additional plate and the heat sink are integrally formed from the same thermally conductive metal material.

[0024] By adopting the above technical solution, the sealing effect is improved, and the heat dissipation effect on the vacuum pump is also improved.

[0025] Optionally, the auxiliary plate and the heat dissipation base plate are connected and located in the cooling cavity, and both the auxiliary plate and the heat dissipation fins are provided with water passage holes for coolant to pass through.

[0026] By adopting the above technical solution, the auxiliary plate and the heat dissipation base plate can achieve heat dissipation at the same time, and the coolant can flow through the water passage, making the coolant flow smoother, thereby further improving the heat dissipation effect on the vacuum pump.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The vacuum pump is cooled by a heat dissipation base plate and multiple heat sinks. At the same time, the liquid delivery mechanism is activated, which makes the coolant flow in the cooling chamber to dissipate heat from the heat sinks and heat dissipation base plate. Air flow also dissipates heat from the heat sinks. Therefore, air cooling and water cooling work together to cool the vacuum pump, thereby greatly improving the heat dissipation effect of the vacuum pump.

[0028] 2. By extending the heat sink to the outside of the cooling plate, the obstruction effect of the cooling plate on the air moving at the heat sink is greatly reduced. This ensures both air cooling and water cooling effects on the heat sink, allowing the air cooling and water cooling effects to work together to better dissipate heat from the vacuum pump, further improving the heat dissipation effect of the vacuum pump.

[0029] 3. The multiple fixing posts facilitate the positioning of the cooling plate. Since the heat dissipation base plate is designed for better heat dissipation, its thickness is relatively small. Therefore, the fixing posts enable threaded connection with the fixing screws. This not only ensures good heat dissipation of the heat dissipation base plate but also improves the convenience of installing the cooling plate, heat dissipation base plate, and multiple heat sinks, further enhancing the heat dissipation effect on the vacuum pump.

[0030] 4. By allowing the coolant located in the cooling chamber to flow into the heat dissipation chamber and then dissipate heat from the heat sink, the contact area between the coolant and the heat sink is increased, greatly improving the heat dissipation effect of the heat sink. At the same time, air can continue to dissipate heat from the heat sink and the auxiliary plate through the ventilation channel, thereby further improving the heat dissipation effect of the vacuum pump.

[0033] The following provides a further detailed description of this application.

[0034] This application discloses an integrated air-cooled and water-cooled heat dissipation vacuum pump.

[0035] Reference Figure 1 An integrated air-cooled and water-cooled vacuum pump includes a vacuum pump 1 and a heat dissipation device 2 installed on the vacuum pump 1. The heat dissipation device 2 dissipates heat from the vacuum pump 1 through both air cooling and water cooling.

[0036] Reference Figures 1-3 The heat dissipation device 2 includes a heat dissipation assembly 21, a cooling plate 3, and a liquid delivery mechanism 4. The heat dissipation assembly 21 has multiple components spaced apart and corresponding to multiple side walls of the vacuum pump 1. The heat dissipation assembly 21 includes a heat dissipation base plate 22 and multiple heat dissipation fins 23 made of the same thermally conductive material, such as copper. The heat dissipation base plate 22 is fixedly installed on the side wall of the vacuum pump 1 and is parallel to the side wall of the vacuum pump 1. The multiple heat dissipation fins 23 are integrally arranged on the side wall of the heat dissipation base plate 22 away from the vacuum pump 1, and the length directions of the heat dissipation fins 23 and the heat dissipation base plate 22 are perpendicular. At the same time, the heat dissipation base plate 22 and the multiple heat dissipation fins 23 cooperate to dissipate heat from the vacuum pump 1.

[0037] Multiple cooling plates 3 are spaced apart and correspond one-to-one with multiple heat dissipation assemblies 21. The following explanation takes the heat dissipation assembly 21 and cooling plate 3 located on the upper surface of vacuum pump 1 as an example. The heat dissipation base plate 22 is horizontal and multiple heat dissipation fins 23 are vertical. The cooling plate 3 is fixedly connected to the upper surface of the heat dissipation base plate 22 by the fixing mechanism 5. A cooling cavity 31 is opened in the cooling plate 3, and the cooling cavity 31 passes through the lower surface of the cooling plate 3 and communicates with the upper surface of the heat dissipation base plate 22. A vertical insertion hole 32 is opened on the cooling plate 3. Multiple insertion holes 32 are spaced apart and correspond to multiple heat dissipation fins 23. The heat dissipation fins 23 extend vertically through the insertion holes 32 to the top of the cooling plate 3.

[0038] Additional plates 33 are fixedly installed on the opposite side walls of two adjacent heat sinks 23. The top and bottom ends of the additional plates 33 and the heat sinks 23 are flush. At the same time, the additional plates 33 and the heat sinks 23 pass through the insertion holes 32. The bottom end of the additional plates 33 is fixedly connected to the upper surface of the heat sink base plate 22. A heat dissipation cavity 34 is opened on the side wall of the additional plates 33 near the heat sinks 23. The heat dissipation cavity 34 is connected to the cooling cavity 31, so that the coolant in the cooling cavity 31 enters and fills the heat dissipation cavity 34, thereby achieving heat dissipation for a larger area of ​​heat sinks 23 and further improving the heat dissipation effect of heat sinks 23. A ventilation channel 37 for air passage is formed between the two adjacent additional plates 33.

[0039] The liquid delivery mechanism 4 is used to input and output coolant into the cooling chamber 31, so that the coolant can circulate in the cooling chamber 31, thereby dissipating heat from the auxiliary plate 33 and heat sink 23 passing through the cooling chamber 31. The auxiliary plate 33 and heat sink 23 are integrally formed from the same metal thermally conductive material. Multiple water passage holes 36 for coolant to pass through are spaced apart on the auxiliary plate 33 and heat sink 23 located in the cooling chamber 31. The water passage holes 36 make the coolant flow more unobstructed and improve the heat dissipation effect on the vacuum pump 1.

[0040] The fixing mechanism 5 includes a fixing ring 51, a fixing plate 52, multiple fixing posts 53, multiple fixing screws 54, and a sealing assembly 6. The fixing ring 51 is fixedly installed on the outer wall of the cooling plate 3 and the fixing ring 51 surrounds the outer side of the cooling plate 3. At the same time, the fixing ring 51 and the cooling plate 3 are flush with the side wall of the heat dissipation base plate 22. The fixing plate 52 has multiple fixing holes 55 for the heat dissipation fins 23 and the auxiliary plates 33 to pass through. The multiple heat dissipation fins 23 and the multiple auxiliary plates 33 pass through the fixing holes 55, so that the fixing plate 52 presses against the side wall of the cooling plate 3 away from the heat dissipation base plate 22, and pushes the cooling plate 3 and the fixing ring 51 against the heat dissipation base plate 22 for positioning.

[0041] Multiple fixing posts 53 are fixedly installed on the upper surface of the heat dissipation base plate 22, and multiple mounting holes 56 are spaced apart on the fixing ring 51. The multiple fixing posts 53 are inserted into the multiple mounting holes 56 and used to position the cooling plate 3. Multiple fixing screws 54 are arranged one-to-one with the multiple fixing posts 53, and all the fixing screws 54 pass through the fixing plate 52. The fixing screws 54 extend into the mounting holes 56 and are threadedly connected to the fixing posts 53. The heads of the fixing screws 54 press against the fixing plate 52 for positioning, thereby pushing the fixing plate 52 against the cooling plate 3, and the cooling plate 3 and the fixing ring 51 against the heat dissipation base plate 22 for positioning.

[0042] The sealing assembly 6 is used to seal the gap between the cooling plate 3 and the heat dissipation base plate 22, and the gap between the heat dissipation fins 23 and the auxiliary plate 33 and the insertion hole 32. The sealing assembly 6 includes a sealing ring 61 and a sealing ring 62. The fixing ring 51 has an annular mounting groove 1 on the side wall near the heat dissipation base plate 22. The cooling cavity 31 is located inside the mounting groove 1. The sealing ring 61 is snapped onto the mounting groove 1. When the fixing ring 51 presses against the heat dissipation base plate 22, the sealing ring 61 also presses against the heat dissipation base plate 22 to seal, thereby achieving the sealing of the gap between the cooling plate 3 and the heat dissipation base plate 22.

[0043] A mounting groove 2 communicating with the fixing hole 55 is provided on the fixing plate 52 at the fixing hole 55. Multiple sealing rings 2 62 are correspondingly provided with multiple mounting grooves 2. The sealing rings 2 62 are snapped onto the mounting grooves 2. When the heat sink 23 and the auxiliary plate 33 pass through the fixing hole 55, the sealing rings 2 62 are sleeved on the heat sink 23 and the auxiliary plate 33. When the fixing plate 52 presses against the cooling plate 3, the sealing rings 2 62 press against the gap between the heat sink 23 and the auxiliary plate 33 and the insertion hole 32 to seal, thereby reducing the risk of coolant leakage in the cooling cavity 31 and the heat dissipation cavity 34.

[0044] The heat dissipation chamber 34 and the cooling chamber 31 cooperate to form a heat dissipation channel 35. The liquid delivery mechanism 4 includes a collection box 41, a pump body 42 and an inlet pipe 43. The collection box 41 is fixedly installed on the side wall of the vacuum pump 1 and is connected to the bottom of the heat dissipation channel 35 at the lowest point, so that the coolant can flow into the collection box 41 under the action of gravity. The pump body 42 is fixedly installed on the collection box 41 and is connected to the inside of the collection box 41. The inlet pipe 43 is fixedly installed on the pump body 42 and the other end of the inlet pipe 43 is connected to the bottom of the heat dissipation channel 35 at the highest point.

[0045] The heat dissipation channels 35 located on two adjacent cooling plates 3 are connected by the connecting component 7, and the coolant enters from the lowest point of the heat dissipation channel 35 and then exits from the highest point of the heat dissipation channel 35, thereby filling the heat dissipation channel 35 with coolant and improving the heat dissipation effect.

[0046] When the pump body 42 is started, the coolant in the collection box 41 flows into the heat dissipation channel 35 through the inlet pipe 43. The coolant fills the heat dissipation channel 35, and then the coolant flows into the next heat dissipation channel 35 through the connecting component 7. After filling the heat dissipation channel 35 again, it flows into the next heat dissipation channel 35 again, and so on, until the coolant flows into the collection box 41 to form a cycle.

[0047] The connecting component 7 includes two connecting pipes 71 and a connecting hose 72. One connecting pipe 71 is fixedly installed on the top of the auxiliary plate 33 or heat sink 23 at the highest point and is connected to the top of the heat dissipation channel 35. The other connecting pipe 71 is fixedly installed on the adjacent cooling plate 3 and is connected to the cooling cavity 31. The two ends of the connecting hose 72 are sleeved on the two connecting pipes 71 and fixed by clamps 73. The clamps 73 can be clamps or steel wires, etc.

[0048] A fan can also be installed on the vacuum pump 1 to accelerate the airflow through the ventilation duct 37, thereby accelerating the heat dissipation of the vacuum pump 1. This structure is existing technology and will not be described in detail here.

[0049] The working principle of this application embodiment is as follows: When the pump body 42 is started, the coolant in the collection box 41 flows into the heat dissipation channel 35 through the inlet pipe 43. The coolant fills the heat dissipation channel 35, and then flows into the next heat dissipation channel 35 through the connecting component 7. This process is repeated until the coolant flows into the collection box 41 to form a cycle. The coolant in the heat dissipation channel 35 dissipates heat from the heat sink 23 and the auxiliary plate 33. At the same time, the air passing through the ventilation duct 37 dissipates heat from the heat sink 23 and the auxiliary plate 33. The heat dissipation base plate 22, the heat sink 23 and the auxiliary plate 33 work together to dissipate heat from the vacuum pump 1. Therefore, the vacuum pump 1 is cooled by both air cooling and water cooling, thereby improving the heat dissipation effect of the vacuum pump 1.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
