Abstract

The invention relates to the technical field of graphene, and discloses a face-to-face movement-based coating device capable of changing clamping size and changing capacity. The device comprises a bottom plate, wherein a cross rod is fixedly connected to the upper portion of the bottom plate, the pressure difference in a storage tube is changed by changing the upper and lower moving distance of apiston, and the content of the sprayed graphene is changed, so that when clamping plates clamp cooling fin of different sizes, different quantity for spray can be adjusted for the cooling fins of different sizes, the whole device is more intelligent and environment-friendly, the waste of raw materials is avoided, and the single function of a traditional coating device is changed; and when a gear rotates, the distance between the clamping plates is changed, the cooling fins of different sizes can be clamped, on one hand, the situation that a coating is not uniform due to shaking of the coolingfins during coating is avoided, on the other hand, the cooling fins of different sizes can be clamped, so that the diversity of the functions of the device can be increased, and the situation that clamping can not be carried out when the cooling fins of different sizes need to be coated is avoided.

Problems solved by technology

[0003] At present, with the continuous increase of chip operating speed, conventional materials have become increasingly difficult to meet the heat dissipation requirements of high-tech products, and the thermal conductivity of graphene is the material with the best thermal conductivity among known materials. Through research, it is found that it will Graphene coating on the surface of the heat sink can improve the heat dissipation effect of the heat sink. When the traditional coating device is in operation, it cannot clamp heat sinks of different sizes, and the function is relatively single. It is generally necessary to replace a new device when clamping, and the operation is more cumbersome, and the amount of coating extruded by the traditional coating device is consistent each time during the coating process, which cannot be adjusted, so that when a small heat sink If the same capacity is used for coating, it will cause the accumulation of raw materials. On the one hand, it will cause waste of raw materials, and on the other hand, it will lead to a thicker coating, which will affect the heat dissipation effect.

[0004] In order to solve the above problems, the inventor proposed a coating device that changes the clamping size and capacity based on relative motion, which has the advantages of clamping and adjusting the amount of coating for heat sinks of different sizes, and solves the problem of The problem of single function and unadjustable capacity ensures more intelligent use of the device during operation, saves raw materials and reduces production costs
