Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, in particular to a vacuum pump cooling device. Background Art

[0002] When the vacuum pump is working, especially when it is under high load or in continuous operation, it will generate a lot of heat. If the heat cannot be effectively dissipated, the internal temperature may be too high, affecting the performance of the pump or even damaging it. Therefore, it is necessary to design a cooling pipeline to cool the vacuum pump.

[0030] Please refer to Figure 1 The present embodiment provides a vacuum pump cooling device 100, which includes a heat dissipation pipeline 20, a water inlet pipe 10 and a water outlet pipe 30. The heat dissipation pipeline 20 is used to exchange heat with the vacuum pump 200. It is understandable that the vacuum pump 200 will generate a large amount of heat when it is working, especially during high load or continuous operation, and the vacuum pump 200 needs to be cooled down. In the present embodiment, by setting the heat dissipation pipeline 20, water-cooling liquid is passed into the heat dissipation pipeline 20. When the water-cooling liquid flows through the heat exchange area on the heat dissipation pipeline 20 close to the vacuum pump 200, part of the heat of the vacuum pump 200 is transferred to the water-cooling liquid in the heat dissipation pipeline 20. The water-cooling liquid flows continuously in the heat dissipation pipeline 20, thereby continuously cooling the vacuum pump 200.

[0031] However, when the heat dissipation pipeline 20 is damaged, the water-cooling liquid leaks from the heat dissipation pipeline 20, and water easily enters the circuit. Therefore, in order to avoid the above situation, in the present embodiment, the water inlet pipe 10 is connected to the water inlet of the heat dissipation pipeline 20. A first valve 11 is provided on the water inlet pipe 10. The first valve 11 can detect the flow rate flowing through the first valve 11. In other words, the first valve 11 can detect the flow rate of the water-cooling liquid flowing from the water inlet pipe 10 into the heat dissipation pipeline 20. Further, a second valve 31 is provided on the water outlet pipe 30. The second valve 31 can detect the flow rate flowing through the second valve 31. In other words, the second valve 31 can detect the flow rate of the water-cooling liquid flowing out of the heat dissipation pipeline 20 to the water outlet pipe 30. The first valve 11 and the second valve 31 of the present embodiment are connected by signal so that the flow signal of the first valve 11 can be transmitted to the second valve 31 and compared with the flow signal of the second valve 31.

[0032] It is understandable that, since the flow rate of the water-cooling liquid in the pipeline is consistent, considering the influence of temperature on the volume of the water-cooling liquid, a certain threshold value and error value can be preset. When the difference between the flow signals of the first valve 11 and the second valve 31 is lower than the preset value, there is no water leakage in the heat dissipation pipeline 20, and the device can operate normally; when the difference between the flow signals of the first valve 11 and the second valve 31 is higher than the preset value, there is a water leakage in the heat dissipation pipeline 20, at this time, the first valve 11 and the second valve 31 are closed, and an alarm is sounded, and the water circuit is disconnected in time to prevent water from entering the circuit.

[0033] Further, the first valve 11 includes a first valve body 111 and a first flow sensor 112. The first flow sensor 112 is arranged inside the first valve body 111, and is used to detect the flow of the water-cooling liquid passing through the first valve body 111, and output the detected flow signal. The second valve 31 includes a second valve body 311 and a second flow sensor 312. The second flow sensor 312 is arranged on the inner wall of the second valve body 311, and is used to detect the flow of the water-cooling liquid passing through the second valve body 311, and output the detected flow signal.

[0034] Specifically, in this embodiment, the vacuum pump cooling device 100 further includes a controller (not shown) for collecting flow signals of the first valve 11 and the second valve 31 and issuing instructions to the first valve 11 and the second valve 31 to control the first valve 11 and the second valve 31 to open or close.

[0035] Furthermore, the first valve 11 is provided with a first flow indicator 113 for indicating the flow of the water coolant passing through the first valve 11. The second valve 31 is provided with a second flow indicator 313 for indicating the flow of the water coolant passing through the second valve 31.

[0036] Specifically, in this embodiment, the first valve 11 and the second valve 31 are both solenoid valves, so that when water leakage occurs in the heat dissipation pipeline 20, the first valve 11 and the second valve 31 can be closed in time by remote control to stop supplying water to the heat dissipation pipeline 20.

[0037] It should be noted that when water leakage occurs in the heat dissipation pipeline 20, the first valve 11 should be closed in time to stop supplying water to the heat dissipation pipeline 20. After stopping the water supply for a period of time, the second valve 31 is closed to prevent the water coolant from flowing back into the heat dissipation pipeline 20. When the heat dissipation pipeline 20 is not supplied with water, the heat dissipation pipeline 20 can be repaired or replaced.

[0038] Furthermore, the first valve 11 is also provided with a first temperature sensor (not shown). The first temperature sensor is arranged on the first valve body 111, and is used to detect the temperature of the water-cooling liquid flowing through the first valve 11. The second valve 31 is also provided with a second temperature sensor (not shown). The second temperature sensor is arranged on the second valve body 311, and is used to detect the temperature of the water-cooling liquid flowing through the second valve 31. It is understandable that the temperature of the water-cooling liquid flowing through the first valve 11 should be lower than the temperature of the water-cooling liquid flowing through the second valve 31. When the difference between the temperature of the water-cooling liquid of the first valve 11 and the temperature of the water-cooling liquid of the second valve 31 is low, it indicates that the heat dissipation efficiency of the heat dissipation pipeline 20 is low. At this time, the heat dissipation pipeline 20 should be checked for abnormalities.

[0039] In order to facilitate replacement of the first valve 11 and the second valve 31, in this embodiment, the first valve 11 and the water inlet pipe 10 are detachably connected. The second valve 31 and the water outlet pipe 30 are detachably connected. Specifically, the first valve 11 and the water inlet pipe 10 are connected via a flange. The second valve 31 and the water outlet pipe 30 are connected via a flange.

[0040] In this embodiment, a first sealing member is provided between the first valve 11 and the water inlet pipe 10. A second sealing member is provided between the second valve 31 and the water outlet pipe 30. Specifically, the first sealing member and the second sealing member are both sealing rubber rings.

[0041] In order to improve the heat dissipation effect of the heat dissipation pipeline 20, in this embodiment, the heat dissipation pipeline 20 includes a plurality of curved portions (not shown). It can be understood that in this embodiment, the heat dissipation is performed by contacting the heat dissipation pipeline 20 with the vacuum pump 200, and the heat dissipation pipeline 20 is set as a curved structure, which increases the contact area between the heat dissipation pipeline 20 and the vacuum pump 200, and improves the heat exchange efficiency between the vacuum pump 200 and the heat dissipation pipeline 20.

[0042] Furthermore, a plurality of heat dissipation fins are provided on the heat dissipation pipeline 20. Specifically, a plurality of heat dissipation fins are plugged in parallel on the heat dissipation pipeline 20, and the heat dissipation fins increase the contact area between the heat dissipation pipeline 20 and the external air, and are used to transfer the heat of the water-cooling liquid in the heat dissipation pipeline 20 to the external air through the heat dissipation fins.

[0043] In order to achieve circulating cooling, in this embodiment, a water tank 40 is connected between the water inlet pipe 10 and the water outlet pipe 30. Specifically, one end of the water inlet pipe 10 away from the heat dissipation pipeline 20 and one end of the water outlet pipe 30 away from the heat dissipation management are respectively connected to the water tank 40. Further, a water pump 50 is also connected between the water inlet pipe 10 and the water outlet pipe 30. Optionally, in this embodiment, the water pump 50 is connected between the water tank 40 and the first valve 11. In other embodiments, the water pump 50 can be connected between the second valve 31 and the water tank 40, which is not limited by the present utility model.

[0044] The coolant flows from the water tank 40 into the water inlet pipe 10, passes through the first valve 11 on the way, and enters the heat dissipation pipeline 20 to cool down the vacuum pump 200. The coolant is heated after heat exchange, flows out of the heat dissipation pipeline 20 into the water outlet pipe 30, passes through the second valve 31 on the way, and then enters the water tank 40 from the water outlet pipe 30. The coolant circulates through the above path under the action of the water pump 50 to continuously dissipate heat for the vacuum pump 200.

[0045] The working principle and process of the vacuum pump cooling device 100 for preventing water leakage of the utility model are:

[0046] The coolant flows through the first valve 11, and the first valve 11 detects a first flow signal. The coolant flows out from the second valve 31, and the second valve 31 detects a second flow signal. The difference between the first flow signal and the second flow signal is calculated. Since the flow rate of the water-cooling liquid in the pipeline is consistent, considering the influence of temperature on the volume of the water-cooling liquid, the flow difference is generally not zero, and the preset value of the flow difference can be set to a certain threshold. When the detected flow difference is higher than the preset value, it is determined that the heat dissipation pipeline 20 has a water leak, and the first valve 11 and the second valve 31 are controlled to be closed, and the water supply of the heat dissipation pipeline 20 is disconnected.

[0047] The beneficial effects of the vacuum pump cooling device 100 of the utility model are:

[0048] The vacuum pump cooling device 100 of the utility model comprises a heat dissipation pipeline 20, a water inlet pipe 10 and a water outlet pipe 30. The heat dissipation pipeline 20 is used for heat exchange with the vacuum pump 200. The water inlet pipe 10 is connected to the water inlet of the heat dissipation pipeline 20. A first valve 11 is arranged on the water inlet pipe 10. The first valve 11 can detect the flow rate flowing through the first valve 11. The water outlet pipe 30 is connected to the water outlet of the heat dissipation pipeline 20. A second valve 31 is arranged on the water outlet pipe 30. The second valve 31 can detect the flow rate flowing through the second valve 31. The first valve 11 and the second valve 31 are connected by signal so that the second valve 31 can receive the flow signal of the first valve 11 and compare it with the flow signal of the second valve 31. When the difference between the flow signal of the first valve 11 and the flow signal of the second valve 31 is higher than the preset value, it can be detected that the heat dissipation pipeline 20 has a water leakage, the first valve 11 and the second valve 31 are closed, and the water circuit is disconnected in time. The vacuum pump cooling device 100 of the utility model can detect water leakage in the heat dissipation pipeline 20 and disconnect the water circuit in time to ensure property and personal safety.
