DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0035] Example 1

[0036] A coolant activation aid for a liquid-cooled cabinet, see Figure 1-Figure 6 , including a base frame 1, a water inlet pipe 2, a heat exchanger 3, a water outlet pipe 4, a surrounding plate 5, a heat dissipation mechanism 6 and an opening and closing mechanism 7. The surrounding plate 5 is welded on the outside of the base frame 1, and the heat exchanger 3 is installed on the rear side of the base frame 1. The right side of the heat exchanger 3 is connected to the water inlet pipe 2, and the left side of the heat exchanger 3 is connected to the water outlet pipe 4. The water inlet pipe 2 and the water outlet pipe 4 are both connected to the base frame 1. The front side of the base frame 1 is provided with a heat dissipation mechanism 6 and an opening and closing mechanism 7. The heat dissipation mechanism 6 and the opening and closing mechanism 7 are used to accelerate the heat dissipation of the coolant, and the opening and closing mechanism 7 is located at the lower side of the heat dissipation mechanism 6.

[0037] The heat dissipation mechanism 6 includes a connecting frame 61, a circulation pipe 62 and a heat sink 63. The connecting frame 61 is welded to the upper front part of the base frame 1, and a pipeline is connected to the right front part of the connecting frame 61. The connecting frame 61 is hollow, and a circulation pipe 62 is installed in the connecting frame 61. The connecting frame 61 is connected to the circulation pipe 62, and the front side of the water inlet pipe 2 is connected to the connecting frame 61. Heat sinks 63 are evenly connected to the circulation pipe 62.

[0038] The opening and closing mechanism 7 includes a connecting bellows 71, a rotating plate 72, a pulley assembly 73, a rack 74, an insertion rod 75, a first spring 76 and a gear 77. A connecting bellows 71 is welded to the upper front part of the base frame 1, and the connecting bellows 71 is located on the lower side of the connecting frame 61. The left front part of the connecting bellows 71 is slidably connected to the rack 74, and the rear side of the rack 74 is slidably connected to the insertion rod 75. A first spring 76 is connected between the insertion rod 75 and the rack 74. A fan is installed at the lower part of the connecting bellows 71, and the rotating plate 72 is evenly rotatably connected to the connecting bellows 71. The pulley assembly 73 is connected between the right sides of the rotating plate 72.

The left key of the rotating plate 72 on the front side is connected to a gear 77, and the gear 77 is meshed with the rack 74.

[0039] The coolant carrying heat enters the circulation pipe 62 through the pipe on the front side of the connecting frame 61. Since the coolant has a long natural heat dissipation period, the heat sink 63 can accelerate the heat dissipation of the coolant. At the same time, people can move the plug rod 75 to the left and pull the plug rod 75 out of the jack of the bellows 71, so that the first spring 76 is stretched, and then the rack 74 is moved to rotate the gear 77, thereby driving the rotating plate 72 on the front side to rotate, and then driving the other rotating plates 72 to rotate through the pulley assembly 73, so as to adjust the The angle of the rotating plate 72 is adjusted to adjust the wind force and direction of the fan connected to the bellows 71 blowing toward the circulation pipe 62. After the adjustment is completed, people insert the plug rod 75 into the jack connected to the bellows 71 to reset the first spring 76 and lock the rack 74. In this way, the wind can be used to accelerate the cooling of the coolant in the circulation pipe 62, improve the cooling efficiency, ensure the activity of the coolant, and the coolant flows out of the circulation pipe 62 into the water inlet pipe 2, then enters the heat exchanger 3 for heat exchange, and finally flows out from the water outlet pipe 4.

[0044] People can manually push the connecting rod frame 91 to the left so that the second spring 92 is compressed. The connecting rod frame 91 drives the temperature measuring probe 93 to move out of the round head recessed column 94 and contact the coolant flowing through the water inlet pipe 2, thereby detecting the temperature of the coolant and displaying the detection result on the display 95. People can directly understand the temperature of the coolant after passing through the heat sink 63 and air cooling through the display 95. Then people loosen the connecting rod frame 91, and the second spring 92 resets, driving the connecting rod frame 91 and the temperature measuring probe 93 to move to the right and reset, and the temperature measuring probe 93 is inserted into the round head recessed column 94.

A second linear spring 106 is connected between the movable plate 105 and the filter box 102.

[0046] The coolant flows through the filter box 102 in the water inlet pipe 2 for filtration to prevent dust from being carried in the coolant in the immersion cooling method, which may reduce the activity of the contaminated coolant. People can manually pull the connecting frame 104 to the front side, so that the connecting frame 104 drives the movable plate 105 to move forward, the second linear spring 106 is compressed, and the movable plate 105 contacts the filter plate inside the filter box 102 to scrape off the impurities attached to the surface of the filter plate to prevent the filter plate from being blocked and affecting the coolant outflow rate.

In this way, the temperature of the coolant can be measured while scraping the filter plate. Then people loosen the connecting frame 104, and the second linear spring 106 resets to drive the connecting frame 104 and the movable plate 105 to reset. The first linear spring 103 resets to drive the movable orifice plate 101 to reset, and the connecting rod frame 91 moves to the right to drive the temperature measuring probe 93 to be inserted back into the round head recessed column 94.
