The check valve 50 comprises a valve body 510, a valve cover 520, a valve seat 530 and an elastic member 540, wherein when the liquid storage tank 20 is installed in the accommodating cavity 110, the second end of the water diversion component presses the valve cover 520 downwards, the valve cover 520 compresses the elastic member 540 to enable the water diversion component, the through holes and the cooling liquid pipe 30 to be communicated, and water-gas communication is achieved; under the condition of taking down the liquid storage tank 20, the elastic piece 540 can push the valve cover 520 upwards to enable the valve cover 520 to reset, so that the valve cover 520 can move upwards to block the through hole of the valve body 510, and the water-air sealing effect is achieved.

In some embodiments, as shown in fig. 10, 11 and 12, the check valve 50 includes: an elastic ring 550, wherein the elastic ring 550 is arranged around the periphery of the water outlet diversion component when the water diversion component is communicated with the cooling liquid pipe 30; an elastic valve body 560 connected under the elastic ring 550, the elastic valve body 560 having a passage 561 provided therein, the elastic valve body 560 being capable of switching between a state of opening the passage 561 and a state of closing the passage 561; wherein, in the case that the priming member is connected to the one-way valve 50, the second end of the priming member can pass through the resilient ring 550 and be inserted into the resilient valve body 560 to open the channel 561; with the priming assembly separated from the check valve 50, the resilient valve body 560 can close the passageway 561.

Under the condition that the liquid storage tank 20 is taken down, the second end of the water diversion assembly is pulled out of the channel 561, the channel 561 of the elastic valve body 560 is closed to form a seam, and the cooling liquid higher than the elastic valve body 560 extrudes the bottom of the elastic valve body 560, so that the seam gap is smaller, a sealing structure is formed, and the water-air sealing effect is achieved. In addition, the check valve 50 formed by combining the elastic ring 550 and the elastic valve body 560 has the advantages of simple structure, simple assembly and low cost.

It should be noted that the elastic ring 550 and the elastic valve body 560 are integrally formed. Further, as an illustration, alternatively, the elastomeric ring 550 and the elastomeric valve body 560 are combined into an inverted cone elastomeric valve body 560.

The coolant at the bottom of the tank 20 can be led out through the water conduit 230, so that the coolant in the tank 20 is circulated sufficiently.

Further, the height of the water outlet nozzle 210 is located above the highest liquid level of the liquid storage tank 20, and the coupling connection is arranged above the liquid level of the liquid storage tank 20, so that the coupling can be completed in the air, the liquid storage tank 20 is placed and aligned more conveniently, no liquid flows back at the coupling connection position in the process of taking away the liquid storage tank 20, the problem of leakage of cooling liquid in the process of installing and taking the liquid storage tank 20 can be avoided, the problem of leakage of liquid in the process of taking away the liquid storage tank 20 is thoroughly solved, and the safety of products is improved.

Further, as shown in fig. 16 and 17, in some embodiments, the inside of the water outlet nozzle 210 is provided with a water passage 211, and a plug 212 is provided below the water outlet nozzle 210, and when the water outlet nozzle 210 is mated with the coolant pipe 30 installed in the body 10, the plug 212 pushes up the check valve 50 so that the water passage 211 communicates with the coolant pipe 30.

In some embodiments, the water conduit 230 is of unitary construction with the inner side wall of the tank body 220, with a spacing of 0.5mm to 20mm between the lower end of the water conduit 230 and the bottom wall of the tank body 220. So that the connection strength between the penstock 230 and the tank body 220 is good, and in addition, the penstock 230 and the tank body 220 can be integrally manufactured for mass production. And, through the integrated into one piece's structure with water conduit 230 and case body 220 design, improved the wholeness of liquid reserve tank 20, reduced spare part quantity, reduced the installation process, improved installation effectiveness. Further, the interval between the lower end of the water conduit 230 and the bottom wall of the tank body 220 is 0.5mm to 20mm, in which, on the one hand, the problem that the interval between the lower end of the water conduit 230 and the bottom wall of the tank body 220 is too small to cause insufficient cross-sectional area of water conduit and not introduce enough cooling liquid can be avoided; on the other hand, the problem that the cooling liquid in the liquid storage tank 20 is not sufficiently circulated because the introduced cooling liquid is not the cooling liquid at the bottommost part of the liquid storage tank 20 can be avoided by excessively increasing the distance between the lower end of the water conduit 230 and the bottom wall of the tank body 220. Further, the distance between the lower end of the water conduit 230 and the bottom wall of the tank body 220 is preferably 1.5mm to 2.5mm.

In some embodiments, as shown in fig. 4, the liquid storage tank 20 further includes a fixing portion 250 provided on the bottom wall of the tank body 220, the water conduit 230 is inserted on the fixing portion 250, and a water inlet communicating the water conduit 230 and the tank body 220 is provided in the circumferential direction of the fixing portion 250, and extends a distance of 0.5mm to 20mm in the height direction of the water conduit 230. Connection between the penstock 230 and the tank body 220 is achieved through the fixing portion 250 provided on the bottom wall of the tank body 220, so that the penstock 230 is detachable, and the penstock 230 and the tank body 220 can be communicated through the water inlet, so that the cooling liquid in the tank body 220 can enter the penstock 230, and the water diversion effect is achieved. Further, the extending distance of the water inlet in the height direction of the water conduit 230 is 0.5mm to 20mm, in which, on the one hand, the problem that the cross-sectional area of the water conduit is insufficient and sufficient cooling liquid cannot be introduced due to the too small extending distance of the water inlet in the height direction of the water conduit 230 can be avoided; on the other hand, the problem that the cooling liquid in the liquid storage tank 20 is not sufficiently circulated because the introduced cooling liquid is not the cooling liquid at the bottommost part of the liquid storage tank 20 because the extending distance of the water inlet in the height direction along the water conduit 230 is too large can be avoided. Further, the extending distance of the water inlet in the height direction of the water conduit 230 is preferably 1.5mm to 2.5mm.

Further, in a specific application, as an example, the fixing portion 250 may optionally include a plurality of L-shaped ribs, and the plurality of L-shaped ribs are spaced apart to form a gap between adjacent L-shaped ribs, while a middle portion of the L-shaped ribs is hollow to facilitate water diversion. The side walls of the L-shaped ribs can limit the inner side walls of the water conduit 230, and the bottom walls of the L-shaped ribs can limit the water conduit 230 up and down.

Furthermore, the value is preferably 8mm to 12.5mm, so that the limit can be effectively realized, the assembly is easy, and the material consumption is minimum.

In some embodiments, as shown in fig. 8 and 13, the spacing H between the spin cover 40 and the water outlet nozzle 210 is 5mm to 100mm. In this range, on one hand, the problem that the heat exchanger 120 cannot be placed in the rotary cover 40 and the placement space of the water outlet nozzle 210 and the protection frame 115 of the liquid storage tank 20 is small due to the fact that the distance between the rotary cover 40 and the water outlet nozzle 210 is too small can be avoided; on the other hand, the gap between the rotary cover 40 and the water outlet nozzle 210 can be prevented from being too large, so that the gap is too large, the product size is large, and a large space is wasted. Further, the distance between the rotary cover 40 and the water outlet nozzle 210 is preferably 30mm to 40mm.

It should be noted that, the coolant in the heat exchanger 120 will flow back after the first pumping device stops working, and the coolant in the final coolant pipe 30 and the coolant in the liquid storage tank 20 are level, which is natural and will not be described in detail herein.
