Specific implementation

[0021] In order to make the purpose, technical scheme and advantages of the utility model clearer, the following will combine the drawings in the utility model, and clearly and completely describe the technical scheme in the utility model.

[0022] Example one, as Figs. 1-2 Shown, a kind of cooling device suitable for air compressor machine liquid cooling assembly, including cooler 1, vertical water tank 2 and centrifugal pump 3, cooler 1 includes hollow pipe body 11, and the inner chamber of pipe body 11 is respectively arranged with cooling liquid inlet pipe 12 and cooling liquid outlet pipe 13 along axial parallel, and the one end of cooling liquid inlet pipe 12 passes out pipe body 11 and is provided with water inlet 14, and the one end of cooling liquid outlet pipe 13 passes out pipe body 11 and is provided with water outlet 15, and the other end of cooling liquid inlet pipe 12 and the other end of cooling liquid outlet pipe 13 are interconnected by communication pipe 16, and the outer surface of pipe body 11 two ends is provided with liquid return port 17 and liquid outlet 18 respectively;

[0023] Vertical water tank 2 lower end is provided with liquid inlet pipe 4, and liquid inlet pipe 4 is connected with the liquid outlet 18 of cooler 1, and centrifugal pump 3 is fixedly installed above vertical water tank 2, and the suction port of centrifugal pump 3 is located inside vertical water tank 2, and the discharge port of centrifugal pump 3 is connected with one end of liquid outlet pipe 5, and the other end of liquid outlet pipe 5 is connected with the cooling liquid inlet of liquid cooling equipment, and the liquid outlet of liquid cooling equipment is connected with one end of liquid inlet pipe 6, and the other end of liquid inlet pipe 6 is connected with the liquid return port 17 of cooler 1, to form closed circulation system.

[0024] Working principle:

[0025] In use, first, the liquid to be cooled (such as water or antifreeze) is pre-filled in the vertical tank 2, and a certain space is left to cope with the thermal expansion and contraction of the liquid. Since the suction port of the centrifugal pump 3 is located inside the vertical tank 2, the centrifugal pump 3 can be used to continuously pump the liquid to be cooled in the vertical tank 2 into the liquid outlet pipeline 5, and then the liquid to be cooled is delivered to the components to be cooled of the liquid cooling device to achieve the purpose of cooling the components to be cooled.

[0026] After the liquid passes through the components to be cooled of the liquid cooling device, the temperature rises, and then it is sent back to the liquid return port 17 of the cooler 1 through the liquid inlet pipeline 6. Then the liquid to be cooled can be discharged along the liquid inlet pipeline 6 into the inner cavity of the pipe body 11 of the cooler 1, and the cooling liquid can be introduced into the cooling liquid inlet pipe 12 through the water inlet 14, so that the cooling liquid flows through the cooling liquid inlet pipe 12, the communication pipe 16 and the cooling liquid outlet pipe 13 in turn, and then exchanges heat with the liquid to be cooled in the inner cavity of the pipe body 11 through the cooling liquid inlet pipe 12 and the cooling liquid outlet pipe 13. The cooler 1 described above can have a larger heat exchange area, so that the cooling efficiency can be effectively improved. After heat exchange, the cooled liquid is again pumped into the vertical tank 2 inside through the liquid outlet pipeline 5 for storage. To complete the entire circulation process. During the entire circulation process, the centrifugal pump 3 provides continuous circulation power to ensure that the liquid continuously flows in the entire circulation system, thereby maintaining the cooling effect.

[0027] In addition, in the present embodiment, the connection between the pipe body 11 of the cooler 1 and the cooling liquid inlet pipe 12 and the cooling liquid outlet pipe 13 can adopt a flange connection, specifically, a flange opening is provided at one end of the pipe body 11, corresponding flange plates are provided at positions close to the water inlet 14 and the water outlet 15 of the cooling liquid inlet pipe 12 and the cooling liquid outlet pipe 13, so that the cooling liquid inlet pipe 12 and the cooling liquid outlet pipe 13 pass through the flange plates and are sealingly and fixedly connected with the flange plates, and then the flange plates are directly fastened and connected with the flange opening of the pipe body 11 through bolts, to ensure the sealing of the cooling liquid flow in the system. Such design not only ensures the reliability of the cooling liquid flow, but also facilitates the installation, maintenance and replacement of the entire cooler 1. In addition, in order to further improve the cooling effect, a plurality of partitions can be provided in the pipe body 11 of the cooler 1 to increase the flow path of the liquid and prolong the residence time of the liquid in the cooler, thereby enhancing the heat exchange efficiency. The plurality of partitions can be designed in a corrugated shape to better promote the turbulent flow of the liquid in the pipe body and further improve the heat exchange efficiency.

[0028] In the second embodiment, as a further preferred solution of the first embodiment, a sealing flange 7 is arranged on the outer side of the suction inlet of the centrifugal pump 3, and the sealing flange 7 is connected to the upper surface of the vertical water tank 2. A sealing gasket 8 is arranged between the sealing flange 7 and the upper surface of the vertical water tank 2. Therefore, when the centrifugal pump 3 is installed on the upper surface of the vertical water tank 2, the sealing flange 7 can be connected to the top of the vertical water tank 2 to compress the sealing gasket 8, so as to effectively ensure the sealing performance of the sealing flange 7 when the sealing flange 7 is installed on the vertical water tank 2, and avoid liquid leakage.

[0029] In the third embodiment, as a further preferred solution of the first embodiment, the cooler 1 is made of a material resistant to corrosion and high temperature. Specifically, a stainless steel material can be used to improve the corrosion resistance and prolong the service life.

[0030] In the fourth embodiment, as a further preferred solution of the first embodiment, a backflow hole 9 is arranged in the suction inlet of the centrifugal pump 3, one end of the backflow hole 9 is connected to the discharge outlet of the centrifugal pump 3, and the other end of the backflow hole 9 is connected to the inner cavity of the vertical water tank 2. By arranging the backflow hole 9, when the system is stopped, the leaked liquid in the discharge pipeline 5 and the centrifugal pump 3 can be returned to the vertical water tank 2 through the backflow hole 9, so as to effectively reduce the risk of liquid leakage.

[0031] In the fifth embodiment, as a further preferred solution of the first embodiment, an observation window is arranged on the side surface of the vertical water tank 2. Through the observation window, the liquid level and state of the liquid in the vertical water tank 2 can be observed, so as to ensure the normal operation of the system.
