All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
Referring to fig. 1-3, the present application provides a liquid cooling circulation heat dissipation system, which includes a main water inlet pipe 100, a water pump 200, a water storage tank 300, a heat sink 400, and a water return pipe 500, which are sequentially connected. The water supply port 110 of the main water inlet pipe 100 and the recovery port 510 of the water return pipe 500 are respectively connected with an input port and an output port of the equipment to be cooled, and when the cooling water circulation heat dissipation system is used, the water pump 200 starts to guide cooling liquid in the water storage tank 300 into the main water inlet pipe 100, the cooling liquid is discharged from the water supply port 110 of the main water inlet pipe 100 into the equipment to be cooled, and after the cooling liquid entering the equipment to be cooled exchanges heat with the equipment to be cooled, the cooling liquid enters the water return pipe 500 through the recovery port 510 of the water return pipe 500, and then flows back into the water storage tank 300 through heat dissipation of the radiator 400, so that a liquid cooling circulation heat dissipation system is formed, and the equipment to be cooled continuously dissipates heat.
In the working process of the liquid cooling circulation heat dissipation system, along with the increment of the temperature of the equipment to be cooled, the liquid cooling circulation heat dissipation system can increase the integral liquid cooling circulation speed by increasing the output power of the pump body, so that the temperature difference between the cooling liquid and the equipment to be cooled is increased, and the heat dissipation efficiency of the equipment to be cooled is improved; however, since the radiator 400 in the liquid cooling circulation heat dissipation system dissipates heat by means of heat exchange, the heat dissipation efficiency is related to time, heat exchange area and heat exchange medium, and when the radiator 400 is used after production, the heat exchange area and the heat exchange medium do not change greatly, so that the heat dissipation efficiency of the radiator 400 is greatly affected by time when in use, when the liquid cooling circulation speed of the whole liquid cooling circulation heat dissipation system is increased, the heat dissipation time of the cooling liquid in the radiator 400 is correspondingly reduced, that is, the cooling effect is correspondingly reduced, and when the cooling liquid flowing out of the liquid return pipe cannot be cooled to a set temperature (the set temperature is greater than 0 ℃ because the cooling liquid temperature cannot be reduced to below 0 ℃ only by means of heat exchange, preferably, within the range of 10 ℃ and 15 ℃), the cooling liquid temperature in the liquid cooling circulation heat dissipation system is increased, and the heat dissipation efficiency of the equipment to be cooled is affected.
It should be noted that, in the above-mentioned case of increasing "when the cooling liquid flowing out of the return pipe cannot be cooled to the set temperature by the radiator 400", specifically, the temperature of the device to be cooled is high, and the cooling liquid can cool the device to be cooled to the proper temperature at the flow rate, but at this time, the temperature of the liquid discharged from the main return pipe 500 is high, and the cooling liquid passes through the radiator 400 at the flow rate for a relatively short time, and the radiator 400 cannot cool the cooling liquid to the set temperature in a relatively short time.
In order not to affect the heat dissipation efficiency of the device to be cooled, in this embodiment, the liquid cooling circulation heat dissipation system further includes a water return mechanism, a water supplementing mechanism and a monitoring control unit, the water return mechanism is disposed between the main water return pipe 500 and the radiator 400, the water return mechanism includes a water return tank 610 for receiving the cooling liquid flowing out of the water return pipe 500, the water return tank 610 is provided with a first pipeline 620 connected with the main water return pipe 500, and a second pipeline 630 connected with an input end of the radiator 400, one end of the second pipeline 630 away from the radiator 400 extends to be communicated with a bottom of the water return tank 610, the water storage tank 300 is a closed tank body, an output end of the radiator 400 is connected with a third pipeline 640, one end of the third pipeline 640 away from the radiator 400 extends to a position above a liquid surface of the water storage tank 300, the water supplementing mechanism includes a water supplementing tank 710 storing the cooling liquid, and a liquid guiding portion 720 capable of guiding the cooling liquid in the water supplementing tank 710 into the water storage tank 300; the monitoring control unit includes a temperature sensor 810 and a controller, wherein the temperature sensor 810 is arranged at the output end of the radiator 400, the temperature sensor 810 can monitor the temperature of the cooling liquid output by the radiator 400 in real time, and when the temperature is higher than the set temperature, the controller can control the liquid guiding part 720 to guide the cooling liquid into the water storage tank 300.
Through the above design, when the water pump 200 is started to lead out the liquid in the water storage tank 300, the liquid level in the water storage tank 300 is lowered, at this time, the negative pressure is formed above the liquid level in the water storage tank 300, the negative pressure can enable the cooling liquid in the recovery tank to continuously enter the radiator 400 for heat dissipation and then flow back into the water storage tank 300, in the process, the water pump 200 can increase the output power of the cooling liquid, namely the liquid circulation speed along with the increment of the temperature of the equipment to be cooled, in the process, the temperature sensor 810 can monitor the temperature of the cooling liquid output by the radiator 400 in real time, when the temperature is higher than the set temperature, the controller controls the liquid guide part 720 to guide the cooling liquid in the water supplementing tank 710 into the water storage tank 300, at this time, because the liquid guide part 720 guides the cooling liquid into the water storage tank 300, the negative pressure above the liquid level in the water storage tank 300 is reduced, and the negative pressure is reduced so that the flow rate of the cooling liquid in the recovery tank enters the radiator 400 is reduced, and the time of the cooling liquid in the radiator 400 is prolonged, so that the cooling effect of the cooling liquid in the radiator 400 is improved, and the cooling effect of the cooling liquid in the radiator 400 is not higher than the set temperature when the cooling liquid flows back into the equipment to the inside.
In this embodiment, the liquid guiding part 720 includes a liquid pipe 721, an electrically controlled flow valve 722, and a solenoid valve 723; one end of the infusion tube 721 is communicated with the bottom of the water replenishing tank 710, the other end of the infusion tube 721 is connected with the top of the water storage tank 300, and an electrically controlled flow valve 722 and an electromagnetic valve 723 are assembled on the infusion tube 721. When the temperature sensor 810 monitors that the temperature of the cooling liquid output by the radiator 400 is higher than the set temperature, the controller controls the electromagnetic valve 723 to open, at this time, under the condition that the liquid level of the water storage tank 300 forms a negative pressure, the controller adjusts the flow of the electric control flow valve 722, so that the cooling liquid in the water supplementing tank 710 is supplemented to the water storage tank 300, in the process, the flow of the electric control flow valve 722 can be adaptively adjusted according to the temperature sensor 810, that is, when the temperature sensor 810 detects that the temperature difference between the temperature and the set temperature is larger, the flow of the electric control flow valve 722 is correspondingly increased, so as to reduce the flow rate of the cooling liquid in the radiator 400 flowing back into the water storage tank 300, prolong the time of the cooling liquid in the water storage tank 400, and improve the cooling effect of the cooling liquid in the radiator 400.
Further, the water replenishment tank 710 is located above the water storage tank 300. When the solenoid valve 723 and the electrically controlled flow valve 722 are opened, they flow to the water tank 300 by themselves under the action of gravity.
In one or more embodiments, the cooling liquid inside the water replenishing tank 710 is not higher than the set temperature, further, an insulation layer is arranged inside the water replenishing tank 710, and ice cubes are placed inside the water replenishing tank 710. By placing ice cubes inside the water replenishing tank 710, the temperature inside the water replenishing tank 710 can be reduced as much as possible, when the cooling liquid inside the water replenishing tank 710 enters the water storage tank 300 through the liquid filling part, the cooling liquid inside the water storage tank 300 can be reduced, and the cooling liquid inside the water storage tank 300 is beneficial to the cooling effect of equipment to be cooled, and the temperature entering the recovery tank can be reduced, so that the temperature of the cooling liquid discharged by the radiator 400 is reduced, and the time for replenishing the cooling liquid into the water storage tank 300 by the water replenishing tank 710 is reduced.
In the process of introducing the coolant into the water tank 300 through the above-described liquid guide 720, the liquid level in the water replenishment tank 710 is continuously lowered, and the liquid level in the water return tank 610 is gradually raised, which results in failure to perform continuous operation for a long period of time. For this reason, in this embodiment, the water replenishing tank 710 is a closed tank, a secondary radiator 900 is disposed between the water replenishing tank 710 and the water return tank 610, the input end and the output end of the secondary radiator 900 are respectively connected with a fourth pipeline 910 and a fifth pipeline 920, and one ends of the fourth pipeline 910 and the fifth pipeline 920, which are far from the secondary radiator 900, extend to communicate with the top of the water replenishing tank 710 and the bottom of the recovery tank.
When the liquid level in the water replenishing tank 710 decreases, a negative pressure is formed above the liquid level in the water replenishing tank 710, under which the cooling liquid in the water returning tank 610 enters the auxiliary radiator 900 through the first fifth pipeline to dissipate heat, and then enters the water replenishing tank 710 through the fourth pipeline 910 to maintain the balance between the water replenishing tank 710 and the liquid level in the water returning tank 610, and it is added that when the controller controls the electromagnetic valve 723 and the electric control flow valve 722 to open, the auxiliary radiator 900 is started simultaneously,
In one or more embodiments, the water supply ports 110 of the main water inlet pipe 100 are provided with a plurality of water return ports of the main water return pipe 500, the number of the water supply ports 110 of the main water inlet pipe 100 is the same, and the water supply ports 110 of the main water inlet pipe 100 and the water return ports of the main water return pipe 500 are detachably provided with sealing plugs. Different numbers of water supply ports 110 and water return ports can be selected to be connected with the equipment according to the use condition of the equipment.
The foregoing is only a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art, who is within the scope of the present application, should make equivalent substitutions or modifications according to the technical scheme of the present application and the inventive concept thereof, and should be covered by the scope of the present application.
