[0026] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manner, structure, features, and effects according to the present invention as follows.
[0027] Please refer to Figures 1 - 4As shown in the figure, the purpose of this embodiment is to provide a double-loop water-cooled heat dissipation device, including a device main body 4. The device main body 4 includes a first cooling loop 2 and a second cooling loop 3. The first cooling loop 2 at least includes a second housing 24. A second heat sink fin 21 is fixedly arranged in the second housing 24. A first cooling pipe 23 penetrates through the second heat sink fin 21. And a second water-cooled fan 22 is fixedly installed on one side of the second heat sink fin 21 to discharge the heat energy in the coolant by the second water-cooled fan 22.
[0028] The second cooling loop 3 at least includes a third housing 33. A second cooling pipe 32 is arranged in the third housing 33. And a third water-cooled fan 31 is fixedly installed on one side of the third housing 33 to discharge the heat energy in the coolant by the third water-cooled fan 31. And the first cooling loop 2 and the second cooling loop 3 are symmetrically arranged up and down.
[0029] Among them, the cooling pipe has a suitable pipe diameter and wall thickness to ensure smooth flow of the coolant and no excessive pressure loss. The flow path of the coolant is in an S shape to ensure that the coolant can fully contact and take away the heat generated by the heat source. The cooling pipe has no right-angle bends to reduce the resistance of the coolant during the flow process.
[0030] And the first cooling loop 2 and the second cooling loop 3 are connected through a heat dissipation loop 1. The heat dissipation loop 1 is used to cool the first cooling loop 2 and pump the coolant to the second cooling loop 3. The second cooling loop 3 is used to cool the back of the heat source and return the cooled coolant to the first cooling loop 2. The heat dissipation loop 1 at least includes a first housing 16. A first heat sink fin 12 is fixedly arranged in the first housing 16. An inlet pipe 13 and a drain pipe 14 penetrate through the first heat sink fin 12 respectively. And a micro water pump 11 for controlling the flow of the coolant is fixedly installed at one end of the inlet pipe 13. The outlet of the micro water pump 11 is connected to one end of the first cooling pipe 23. The inlet of the micro water pump 11 is connected to one end of the inlet pipe 13. And a first water-cooled fan 15 is fixedly installed on one side of the first heat sink fin 12 to discharge the heat energy in the coolant by the first water-cooled fan 15.
[0031] One end of the inlet pipe 13 and the drain pipe 14 are respectively connected to both ends of the first cooling pipe 23. The other ends of the inlet pipe 13 and the drain pipe 14 are respectively connected to both ends of the second cooling pipe 32. And the inlet pipe 13, the drain pipe 14, the first cooling pipe 23 and the second cooling pipe 32 form a circulating closed loop to realize the circulating cooling of the coolant.
[0032] In this device, the dense heat dissipation fins can increase the heat exchange area between the coolant and air or the external environment to improve the heat dissipation efficiency. The first heat dissipation fins 12 and the second heat dissipation fins 21 are rectangular and are arranged longitudinally as a whole. The material of the heat dissipation fins is copper, which improves the heat conduction performance and corrosion resistance of the heat dissipation fins. Moreover, the liquid inlet pipe 13, the liquid discharge pipe 14, the first cooling pipe 23 and the second cooling pipe 32 are all arranged in an S-shaped loop and penetrate through the heat dissipation fins, so as to increase the contact area between each coolant pipe and the heat dissipation fins, thereby improving the heat dissipation efficiency.
[0033] When the present utility model is specifically used, first, this device is fixedly installed on the integrated diversion plate power supply, and then the device is turned on. Under the action of the micro water pump 11, the coolant enters one end of the first cooling pipe 23 from one end of the liquid inlet pipe 13 and flows to one end of the liquid discharge pipe 14, and then enters one end of the second cooling pipe 32 from the other end of the liquid discharge pipe 14 and flows to the other end of the liquid inlet pipe 13 to form a closed loop for cyclic operation. The coolant in the second cooling loop 3 flows. Since the coolant in the second cooling pipe 32 has passed through the heat dissipation loop 1 at this time, by blowing air to the back of the heat source through the third water-cooled fan 31, while cooling the back of the heat source, the temperature of the coolant flowing back to the heat dissipation loop 1 is further reduced through the third water-cooled fan 31; the coolant in the first cooling loop 2 continuously flows, carrying part of the heat energy of the heat source, and the heat absorption efficiency is improved through the second heat dissipation fins 21. The heat energy of the second heat dissipation fins 21 is discharged through the second water-cooled fan 22. The heat energy in the heat dissipation loop 1 is transferred to the first heat dissipation fins 12 through the liquid discharge pipe 14 and discharged from the device through the first water-cooled fan 15. The double-loop water-cooled heat dissipation of the heat source is realized by the first cooling loop 2 and the second cooling loop 3.
[0034] The above is only the preferred embodiment of the present utility model and does not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to it as an equivalent embodiment within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any brief modification, equivalent change and modification made to the above embodiment based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
