Description

technical field [0001] The invention relates to a radiator for heat dissipation of high-power electronic devices, in particular to a thermal superconducting fin radiator and an electrical equipment case. 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 during work is also increasing. If the heat generated by the power devices cannot be dissipated in time and quickly, it will lead to power failure. The temperature of the chip in the de...
