Description

Technical Field

[0001] The invention relates to the technical field of liquid cooling cabinets, and in particular to an integrated liquid cooling cabinet capable of circulating heat dissipation. Background Art

[0002] An integrated liquid cooling cabinet is a cabinet used to cool electronic equipment. It usually includes two cooling methods: spray type and immersion type. The immersion type means placing the electronic equipment in a closed cabinet and passing heat transfer oil through the heat source part of the electronic equipment. The high thermal conductivity of the liquid is used to transfer the heat from the equipment to the liquid. The heat is then discharged through a circulating cooling system and dissipated to the outside to ensure the stable operation of the equipment. In the prior art, the circulating cooling process usually uses a water pump to extract the heat transfer oil from the heat transfer position at high pressure, and then input it into the condenser to dissipate heat. However, the water pump itself cannot adjust the water pressure, and generally needs to be equipped with a pressure relief valve or a branch pipe for pressure reduction operation. In this way, the water pump consumes a lot of energy, and the use of a pressure relief valve to reduce the pressure will lose energy, resulting in waste; In addition, the high-pressure heat transfer oil output by the water pump may also cause continuous damage to the condenser, reducing its working efficiency and service life.

[0019] The effects achieved by this embodiment are as follows: compared with the prior art of using a water pump to extract the heat transfer oil at high pressure for circulating heat dissipation, the circulation boosting mechanism 7 is provided to slow down the flow rate of the heat transfer oil in the liquid cooling cavity 2, and the speed-changing motor is used to adjust the flow rate of the heat transfer oil in real time, so that heat transfer is more effective, avoiding the use of a water pump to first increase a high water pressure and then using a pressure reducing valve to reduce the pressure, thereby reducing energy loss and improving the heat dissipation effect.

[0021] The effects achieved by this embodiment are as follows: compared with the prior art of using a pressure relief valve to control the circulating addition of heat transfer oil, the auxiliary drainage mechanism 8 can use the push-pull force of the circulating boosting mechanism 7 to drive the guide fan 86 to rotate, thereby accelerating the flow of the heat transfer oil, making more effective use of mechanical energy and avoiding the heat transfer oil being in a high-pressure state and causing continuous damage to the condenser 5.

[0022] The complete usage steps and working principle of the above embodiment are as follows: In the initial state: the telescopic rod 74 is in the top position, the threaded pressure ring 77 is located at the top of the boost cylinder 71, the disc 79 and the vertical through hole 78 on the threaded pressure ring 77 are in the same position, that is, the heat transfer oil can pass through the open state, and the variable speed motor and the condenser 5 are in the closed state.

[0023] The following is the working process of the circulating pressurizing mechanism 7 to reduce energy loss and improve heat dissipation effect: When in use, the electronic equipment placed in the liquid cooling cavity 2 will generate heat during operation. Due to the gravity of the heat transfer oil itself, the inside of the boost cylinder 71 is filled with heat transfer oil through the liquid outlet pipes 72 on both sides. At this time, the variable speed motor is started to drive the eccentric wheel 76 to rotate. Since the rotating rod 1 75 will rotate with the edge of the eccentric wheel 76 as the axis, and the telescopic rod 74 is limited by the boost cylinder 71, the telescopic rod 74 will be driven by the rotating rod 1 75 to perform reciprocating lifting and lowering motion, thereby driving the disc 79 to move accordingly, intermittently pressurizing the heat transfer oil, and dissipating the heat from the connecting pipe 1 73 to the condenser 5, and then returning to the liquid cooling cavity 2 for recycling. The speed of the variable speed motor can be changed according to the actual heat dissipation demand, so as to achieve the purpose of controlling the flow rate of the heat transfer oil. The threaded pressing ring 77 is pressed to the bottom of the boost cylinder 71 from the initial state, and performs two positive and negative rotations. After the initial state starts to be pressurized, it first passes through the top threaded section 710 to cause the threaded pressing ring 77 to rotate, which just misaligns the threaded pressing ring 77 with the vertical through hole 78 on the disc 79, so that the threaded pressing ring 77 and the disc 79 are not connected to each other, and become a closed state, pressurizing the heat transfer oil in the boost cylinder 71. After the threaded pressing ring 77 is pressed down to the bottom, it rotates in the opposite direction when passing through the lower threaded section 710, so that the threaded pressing ring 77 returns to the initial state, while the internal disc 79 does not rotate. At this time, the top space of the boost cylinder 71 is also filled with heat transfer oil. Finally, when the disc 79 and the threaded pressing ring 77 rise in a reciprocating motion, the concave portion of the threaded pressing ring 77 is used for buffering, and then the heat transfer oil passes through the vertical through hole 78, reducing the pressure of the heat transfer oil accumulated on the top of the boost cylinder 71 and reducing the resistance of the disc 79 and the threaded pressing ring 77 to rise. Please refer to the above working process Figures 1 to 6 .

[0024] The following is the working process of the auxiliary drainage mechanism 8 to fully utilize the mechanical energy and avoid continuous loss of the condenser 5: When in use, the telescopic rod 74 performs lifting and reciprocating motions, and at the same time, the lifting rod 83 fixed thereon also performs lifting and reciprocating motions. Since the end of the rotating rod 84 away from the lifting rod 83 is fixed to the side wall edge of the guide fan 86, the guide fan 86 is driven to rotate. At this time, the heat transfer oil cooled from the condenser 5 enters the protective shell 82 through the connecting pipe 81, and the blades of the guide fan 86 are constantly moved to accelerate the heat transfer oil to the bamboo hat-shaped pipe 85, and then enter the top cold liquid pipe 87, and finally flow into the liquid cooling cavity 2 to circulate and cool the electronic equipment inside. Please refer to the above working process Figures 7 to 9 .

[0025] Summary: By setting up the circulating pressurizing mechanism 7, the eccentric wheel 76 is used to drive the telescopic rod 74, the disc 79 and the threaded pressure ring 77 to perform reciprocating lifting and lowering motions, which can slow down the flow speed of the heat transfer oil in the liquid cooling cavity 2, and cooperate with the variable speed motor to adjust the flow rate of the heat transfer oil in real time, so that the heat transfer is more effective. In addition, the threaded pressure ring 77 performs two positive and negative rotations when pressurized, which reduces the resistance of the disc 79 and the threaded pressure ring 77 to rise. At the same time, the lifting and lowering reciprocating motion of the telescopic rod 74 will drive the lifting rod 83 to move accordingly, and then drive the guide fan 86 to rotate through the rotating rod 84, so as to accelerate the heat transfer oil to the liquid cooling cavity 2, and make full use of mechanical energy to avoid the heat transfer oil being in a high pressure state and causing continuous loss to the condenser 5.
