Abstract

The invention provides a thermally superconducting plate and a manufacturing method thereof. The thermally superconducting plate comprises a first cover plate; The second cover plate comprises a coverplate main body and an annular convex edge, wherein the annular convex edge is integrally connected with the cover plate main body; A first cover plate is attached to a surface of the annular convexedge remote from the cover plate body to form a sealed chamber between the first cover plate and the cover plate body; At least one baffle plate is located in that sealed chamber; The air guide plateincludes a plurality of convex portions spaced apart in the first direction and extending in the second direction, the bottom of the adjacent convex portions in the first direction are integrally connected, and a gap is arranged between the inside of the convex portions and the adjacent convex portions so that the air guide plate, the first cover plate and the second cover plate form a sealing passage communicating with each other; The sealed channel is filled with heat transfer working fluid. The thermal superconducting plate of the invention has the advantages of good homogeneity of temperature, strong thermal diffusion ability, small thermal resistance, high heat dissipation efficiency, large heat dissipation ability, compact structure, small volume, light weight, wide application rangeand the like.

Description

technical field [0001] The invention belongs to the technical field of heat transfer, and in particular relates to a thermal superconducting plate and a manufacturing method thereof. Background technique [0002] With the rapid development of power electronics technology, the requirements for modularization, integration, lightweight, low cost and high reliability are getting higher and higher. Therefore, in solar inverters, uninterruptible power supplies (UPS), charging piles, power MosFET (metal oxide semiconductor field effect transistor), Diode (diode), IGBT ( Power devices such as insulated gate bipolar transistors), CPUs, GPUs (graphics processing units) and computing power boards. As the integration of these power components is getting higher and higher, the power density is also increasing, and the heat generated by themselves is also increasing during work, and the heat flux density is getting higher and higher. The conduction and dissipation of heat will cause the...
