Abstract

A high-power thermally superconducting plate-fin combined radiator is composed of several spaced thermally superconducting plates with intercommunicating heat transfer channels filled with heat transfer working medium. A plurality of bottom substrate spacers are positioned between adjacent thermal superconducting plates and attached to the surface of the thermal superconducting plate; At least oneside of that space strip of the bottom substrate is provided with a groove on the surface contacting with the thermal superconducting plate; The surface of the thermally superconducting plate contacting with the partition strip of the bottom substrate is provided with a connecting through hole for communicating the heat transfer channel with the channel. The heat dissipation fin is located on atleast one surface of the thermal superconducting plate and above the bottom substrate spacer. The grooves on the two sides of the base plate spacer strip in the high-power thermally superconducting plate-fin combined radiator of the invention can be used as buffer and storage areas of the heat transfer working substance, balance the distribution of the heat transfer working substance, play the role of communication or isolation between the thermally superconducting plates, and also play the role of increasing the heating area of the heat transfer working substance.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation equipment, in particular to a high-power thermal superconducting plate-fin combined radiator. 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 device rises, which will...
