Description

Technical Field

[0001] The utility model relates to the technical field of heat-conducting interface material processing, in particular to a calendering device for heat-conducting interface material. Background Art

[0002] With the development of new technologies, new products with "high heat flux density, high power, high stability, thermal response, and ultra-thin" have put forward higher requirements for thermal interface materials. Thermal interface materials can solve the heat dissipation problem of electronic equipment. They are used between the contact interface of the heat source and the radiator. By using thermal interface materials with a thermal conductivity much higher than that of air, the heat dissipation efficiency of electronic components can be improved. With the iteration and update of electronic devices, 5G communications, new energy and optoelectronic modules, the increasingly harsh application environment has put forward higher requirements for thermal interface materials. On the basis of high thermal conductivity, they must also have excellent reliability; the process of making semi-finished products such as films by heating the mixed rubber through the gap between two relatively rotating and horizontally set rollers is called calendering. It mainly includes several processes such as material preparation, mixing, plasticization and feeding to the calender.

[0003] For example, the utility model with application number 20202275459.3 discloses a calendering device for thermally conductive interface materials. By setting a matching structure of a flow-limiting baffle and a baffle delivery device, the baffle is used to limit the flow of the thermally conductive interface material, which lays a good foundation for producing thermally conductive gaskets with uniform thickness. It not only reduces the production process, but also improves the product quality and yield of the thermally conductive gaskets. In addition, in the present technical solution, the left baffle and the right baffle can be made of low-cost materials, which can reduce the waste of raw materials and reduce production costs.

[0004] Similar to the above application, there are still some shortcomings:

[0005] The heating and cooling parts of the calendering device of this type of thermal interface material have problems such as uneven heating or cooling. First, the temperature cannot be adjusted according to demand to achieve appropriate heating or cooling functions, and the material properties cannot be well controlled. Secondly, problems such as uneven heating or cooling may occur, which may easily lead to differences in the ductility of various parts of the thermal interface material, affecting the calendering work.

[0006] Therefore, a calendering device for thermal conductive interface material is designed to optimize the above problems. Utility Model Content
