Description

technical field [0001] The invention belongs to the technical field of heat transfer, in particular to a thermal superconducting plate-finned heat sink with fins on the surface. 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 ( Insulated Gate Bipolar Transistors) and other power devices. 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 temperature of the chip in the power device to rise, which will cause...
