10. A method for using a reactive power compensation cabinet with good heat dissipation, using the reactive power compensation cabinet with good heat dissipation as claimed in claim 9, characterized in that: The method steps are as follows: S1: Rapid cooling; during the process of the internal thread block (504) moving towards the driving motor (502), the water pressure will keep the T-shaped hollow block (602) stationary in the T-shaped groove (601). The water inlet hole (604) and the T-shaped hollow block (602) will push the water towards the water pipe (507) in the direction of the driving motor (502). The water will pass through a number of cooling pipes (505), two connecting pipes (506), two filter pipes (508) and the filter box (509), and finally the water will flow back into the cooling water tank (501). During this process, since the cooling pipes (505) are in close contact with the heating element (4), the heat generated by the heating element (4) will be transferred to the cooling pipes (505). The water in the cooling pipes (505) will带走 the heat generated by the heating element (4). Due to the large specific heat capacity of water, the water can effectively cool the heating element (4) and improve the cooling efficiency. S2: Circulation cooling; when the internal thread block (504) moves away from the drive motor (502), water will enter the T-shaped groove (601) through the water inlet hole (604) under the action of the water pressure in the cooling water tank (501), and the water will push the T-shaped hollow block (602) to leave the T-shaped groove (601). At this time, the adaptive spring (603) undergoes tensile deformation, and after the drainage hole (605) on the T-shaped hollow block (602) leaves the T-shaped groove (601), the water in the T-shaped hollow block (602) will be discharged from the drainage hole (605), thereby ensuring that when the internal thread block (504) moves away from the drive motor (502), the water in the cooling water tank (501) will not flow back, so that the water with heat will remain in the cooling water tank (501), and the water with lower temperature will remain in the cooling pipe (505) close to the heating element (4), thereby ensuring continuous cooling of the heating element (4); S3: Accelerating the cooling rate; during the rotation of the reciprocating screw (503), the fan blade (702) is driven to rotate, and the rotation of the fan blade (702) generates a suction force, which draws air to the outside through the circular tube (705), the circular reciprocating screw groove (703) and the perforated circular plate (704). The wind is blown upward through the bellows (701), the L-shaped tube (706) and the exhaust hood (707). The wind passes through the two perforated plates (3) and passes through a plurality of heating elements (4) and the cooling tube (505). The wind takes away the heat from the heating element (4), and the wind can also dissipate heat from the cooling tube (505), allowing the water in the cooling tube (505) to dissipate heat quickly, thereby increasing the cooling rate of the water; S4: Prevent short circuit; When the circular movable plate (805) moves in a direction close to the bellows (701), it rotates at the same time. The circular movable plate (805) drives the shaped plate (806) to move synchronously. The shaped plate (806) drives the round roller (807) to move synchronously. When the round roller (807) contacts the water-absorbing sponge (802), as the round roller (807) rotates, the round roller (807) rotates and squeezes out the water on the water-absorbing sponge (802). The squeezed water flows into the inclined groove (803) and flows along the slope of the inclined groove (803) to the outside of the heat dissipation cabinet (1). In this process, moisture in the outside air can be effectively prevented from entering the heat dissipation cabinet (1), thereby causing a short circuit of the electronic components in the heat dissipation cabinet (1) and affecting the normal operation of the heat dissipation cabinet (1).
