The implementation principle of the embodiment is as follows:

when the yoga mat placed on the workbench 13 is punched by the punching machine body 11, the cutting knife on the cutting machine body is in contact with the workbench 13, and heat is transferred to the workbench 13. In the process, the water cooling pump 22 pumps the cooling liquid in the water cooling tank 21 through the water inlet pipe 23 and delivers the cooling liquid into the heat radiating coil through the water delivery pipe 24. Because the heat dissipation coil is located in the workbench 13, the process that the cooling liquid flows along the heat dissipation coil is the heat exchange process of the cooling liquid and the workbench 13, so that the heat on the workbench 13 is taken away, and the purpose of dissipating heat of the cutting knife on the punching machine body 11 is achieved.

And the long-time working state causes the temperature of the cooling liquid to rise, so that heat exchange can not be well carried out, and the additionally arranged cooling device 3 can cool the cooling liquid, so that good heat exchange capability of the cooling liquid is maintained. That is, the cooling liquid flowing out of the heat radiating coil first flows into the cooling case 41 through the return pipe 26, and since the plurality of first and second

heat radiating fins

42 and 43 connected to each other in a perpendicular cross manner are provided in the cooling case 41, the cooling liquid transfers heat to the first and second

heat radiating fins

42 and 43, and thus the heat is transferred to the outside for heat radiation by heat exchange between the first heat radiating fin 42 and the air. The cooling by the preliminary heat dissipation flows into the second cooling mechanism 5 through the connection pipe 44 to further dissipate the heat.

The cooling liquid cooled by the first cooling mechanism 4 flows into the cooling coil 51 through the connection pipe 44, and exchanges heat with air through the cooling coil 51 to cool the cooling liquid. In this process, the wavy cooling fins 53 can increase the heat exchange area of the cooling coil 51 to improve the cooling effect on the cooling liquid. The coolant cooled by the second cooling mechanism 5 flows into the recovery pipe 52 and finally flows back into the cold water tank 21.

In this process, the starting state of the centrifugal fan 7 is maintained, and when the centrifugal fan 7 is in operation, the air in the air suction hood 71 can be extracted through the air inlet, and the air suction hood 71 faces the first heat dissipation fin 42, so that the centrifugal fan 7 can extract the air near the first heat dissipation fin 42, and the heat exchange efficiency between the air and the first heat dissipation fin 42 is increased.

Due to the structural characteristics of the centrifugal fan 7, the axis of the air inlet of the centrifugal fan 7 is perpendicular to the axis of the air outlet, and the first cooling mechanism 4 and the second cooling mechanism 5 are located on the same side of the centrifugal fan 7. The additional air guide 72 can turn the air blown out from the air outlet of the centrifugal fan 7 through the air guide bent tube 721, blow the air through the air guide cover 722, and blow the air onto the cooling coil 51 to further dissipate the heat of the cooling liquid in the cooling coil 51, thereby further improving the heat dissipation effect of the second cooling mechanism 5 on the cooling liquid.

However, since the cooling coil 51 has a large weight, it is necessary to secure the installation stability of the cooling coil 51. When the cooling coil 51 is installed, the cooling coil 51 is only required to be clamped between the second clamping pieces 622, the cooling coil 51 can push the two second clamping pieces 622 to be away from each other, and the two second clamping pieces 622 respectively drive the first clamping piece 621 and the installation plate 61 to rotate relatively. The guiding piece 624 guides the installation of the cooling coil 51 to reduce the possibility of the second clamping piece 622 and the cooling coil 51 being stuck.

In this process, two second clamping pieces 622 drive an elastic piece 623 respectively, make elastic deformation take place for elastic piece 623, then after cooling coil 51 card goes into between two second clamping pieces 622, the power that elastic piece 623 resumes deformation can promote two second clamping pieces 622 and be close to each other to carry out the centre gripping to cooling coil 51, thereby with the stable installation on water-cooling box 21 of cooling coil 51.

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.
