The cover plate 4 on the ground side of the heat sink 51 is also vertically provided with a cooling fan 55, and the cooling fan 55 is perpendicular to the heat sink 51.

The implementation principle of the embodiment is as follows:

after heat on the workpiece and the equipment is absorbed by cooling liquid through heat exchange, the cooling liquid enters the liquid storage tank 1 through the liquid inlet pipe 11, and although the temperature of the cooling liquid is reduced to some extent after a series of treatments, the temperature of the cooling liquid is still high due to no active heat dissipation. At this moment, the temperature of the cooling liquid is transmitted to the cooling plate 21 through the side wall of the liquid storage tank 1, flowing cooling water flows into the heat exchange cavity 22 formed in the cooling plate 21, the contact area between the cooling plate 21 and the cooling water is increased by the heat exchange columns 24 and the heat exchange fins 25, namely, the heat exchange areas of the cooling plate 21 and the cooling water are increased, and the temperature of the cooling liquid can be taken away by the cooling water.

In the process, because the flowing direction of the cooling water is opposite to the flowing direction of the cooling liquid, the temperature of the cooling water along the flowing direction is higher and higher, and the temperature of the cooling liquid along the flowing direction is lower and lower; at this time, the cooling liquid with the lowest temperature transfers heat to the cooling water with the lowest temperature, and the cooling liquid with the highest temperature transfers heat to the cooling water with the highest temperature, namely, the cooling liquid can be cooled along the whole flowing direction.

The reading of the thermometer 14 in the observation tube 13 can now be read and the flow of cooling water can be regulated by the regulating member 3 in accordance with the reading on the thermometer 14 to control the cooling effect on the cooling liquid. When the flow of the cooling water needs to be adjusted, an acting force is applied through the handle 35 to rotate the rotating rod 34, the rotating rod 34 rotates to drive the adjusting ball 32 to rotate in the shell 31, the rotating of the ball drives the adjusting hole 33 to rotate, the part of the adjusting hole 33 communicated with the shell 31 changes accordingly, when the adjusting hole 33 is completely communicated with the inner cavity of the shell 31, the flow of the cooling water is the largest, and when the adjusting hole 33 is shielded by the inner side wall of the shell 31 and is not communicated with the inner cavity of the shell 31, the flow of the cooling water is zero.

After the heat is transferred to the cooling water, the temperature of the cooling water rises, and then the cooling water transfers the heat to the cover plate 4 and transfers the heat to the radiating fins 51 through the cover plate 4, and the radiating fins 51 increase the radiating area of the cover plate 4, thereby improving the radiating effect of the cooling water. In this process, since heat is likely to accumulate in the flow channels between the fins 51, the cooling fan 55 blows the air flow to blow out the hot air in the flow channels between the fins 51, and the high-flow-rate air exchanges heat with the fins 51, thereby further improving the cooling effect of the cooling mechanism 2 on the coolant.

Since the fins 51 are easily deformed by an external force, once the adjacent fins 51 are bonded by the deformation, the heat dissipation area of the fins 51 is reduced, and the heat dissipation effect is also reduced; the additional fixing piece 53 and the positioning piece 54 form a support for the heat sink 51, so that the heat sink 51 is not easy to deform, and the possibility of reduction of the heat dissipation effect caused by deformation of the heat sink 51 is reduced.

The added rubber leakage-proof pad 41 is deformed by pressure during installation, so that the sealing performance between the cover plate 4 and the cooling plate 21 is improved, and the possibility of cooling water leakage is reduced.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
