[0025] A guide plate 14 is installed at the bottom of the movable plate 7 near the placement plate 2, and a collection tank 15 is opened at the top of the detection table 1 below the guide plate 14, and a return pipe 16 is installed on one side of the collection tank 15, and the return pipe 16 is connected to the external water supply circulation equipment;

[0026] The collecting groove 15 is located below the groove 3 on one side, the bottom end surface of the guide plate 14 is inclined, and the guide end of the guide plate 14 is always located above the collecting groove 15 during the movement process;

[0027] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the guide plate 14 and the groove 3 are used to take advantage of the water-cooled plate after detection, and the remaining coolant in the flow channel interface can directly fall into the collection tank 15 for recycling, thereby reducing waste and protecting the cleanliness of the surface of the detection table 1, and reducing the wiping work after detection;

[0028] Rollers 13 are installed on both sides of the bottom of the moving plate 7, the bottom of the roller 13 abuts against the top of the detection platform 1, and fixed cylinders 10 are welded on both sides of the top of the moving plate 7;

[0029] Water flow sensors 18 are installed on the outside of the two fixed cylinders 10, and the detection ends of the water flow sensors 18 penetrate into the interior of the flow guide pipe 11. The two flow guide pipes 11 are used as water inlet pipes and water outlet pipes respectively.

[0030] A flow guide tube 11 is passed through the interior of the fixed tube 10, and a docking joint 12 is installed at one end of the flow guide tube 11 close to the placement plate 2;

[0031] The positions of the two docking joints 12 correspond to the positions of the water cooling plate flow channel interfaces on the placement plate 2 on a one-to-one basis. The docking joints 12 move left and right relative to the placement plate 2 through the cooperation of the electric telescopic rod 8 and the moving plate 7.

[0032] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, when in use, the electric telescopic rod 8 and the docking joint 12 are used to synchronously dock the two flow channel interfaces on the water-cooled plate after placement, which has higher installation efficiency and is conducive to improving the detection operation efficiency;

[0033] One end of the butt joint 12 extends to the outside of the fixed tube 10, and a locking sealing mechanism 19 is connected to the outside of the butt joint 12 and one end of the fixed tube 10, so that the butt joint 12 can be automatically sealed when inserted into the water-cooled plate, and the other ends of the two guide pipes 11 are connected to an external water supply circulation device;

[0034] The locking and sealing mechanism 19 includes a fixing sleeve 1901 sleeved on the outside of the fixing tube 10 near one end of the placement plate 2, and an outer air bag 1902 is installed on the side of the fixing sleeve 1901 near the placement plate 2, and an inner expansion air bag 1903 is sleeved on the outer end of the docking joint 12, and connecting tubes 1904 are installed on both sides of the inner expansion air bag 1903 near the fixing sleeve 1901, and one end of the connecting tube 1904 is connected to the inner side of the outer air bag 1902;

[0035] The connecting pipe 1904 is L-shaped, and the outside of the connecting pipe 1904 is fixed by welding to the fixing ring 20 on the outside of the joint 12;

[0036] The inner diameter of the outer airbag 1902 is larger than the inner diameter of the water cooling plate flow channel interface, and the outer diameter of the inner expansion airbag 1903 is matched with the inner diameter of the water cooling plate flow channel interface. The inner expansion airbag 1903 is closer to the water cooling plate flow channel interface than the outer airbag 1902.

[0037] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when in use, the inner expansion airbag 1903 is utilized to fill the gap in the interface effectively, thereby improving the tightness of the docking between the docking joint 12 and the water-cooled plate flow channel interface, and the fixing tube 10 is squeezed toward the water-cooled plate in combination with the compression of the outer airbag 1902 to achieve the self-inflating effect inside the inner expansion airbag 1903, thereby further improving the tightness of the docking between the docking joint 12.

[0038] Working principle: When the utility model is used, the water-cooling plate is first placed on the top of the placement plate 2, so that the flow channel interface of the water-cooling plate faces the docking joint 12, and the convex block 5 and the second side plate 6 are used to limit the water-cooling plate on all sides;

[0039] Secondly, start the electric telescopic rod 8 to extend, so that it pushes the moving plate 7 to approach the water-cooled plate, and then the roller 13 rolls on the test bench 1, so that the docking joint 12 is inserted into the water-cooled plate flow channel interface, so that the inner expansion airbag 1903 is squeezed with the inner wall of the flow channel, and as the fixed tube 10 is squeezed close to the water-cooled plate, the water-cooled plate compresses the outer airbag 1902, so that the gas inside the outer airbag 1902 enters the inner expansion airbag 1903 along the connecting pipe 1904, so that the inner expansion airbag 1903 has a certain expansion effect, so as to lock the docking joint 12 and the water flow plate flow channel interface, improve the docking tightness of the two, and at the same time improve the sealing effect to avoid water seepage;

[0040] Finally, start the external water supply circulation equipment, so that the coolant enters the water-cooled plate flow channel along one of the guide pipes 11 and the docking joint 12, and then is discharged from the other docking joint 12. In this process, the water flow sensor 18 is synchronously started to detect the amount of water flowing through the two guide pipes 11, and the data is compared to confirm the patency of the water-cooled plate flow channel. When the detection is completed, start the electric telescopic rod 8 to reset, so that the docking joint 12 is moved out of the water-cooled plate flow channel interface, and the guide plate 14 is moved to the bottom of the water flow plate flow channel interface. The groove 3 on one side is used to lift the water-cooled plate for picking up. When there is residual coolant in the water-cooled plate flow channel interface, it falls to the guide plate 14 and enters the collection tank 15, and then refluxes to the external water supply circulation equipment through the reflux pipe 16 to prevent the coolant from contaminating the surface of the test bench 1.
