Heat pipe radiator for eliminating heat of electric component

Abstract

A kind of heat pipe radiator for eliminating heat of exothermic electronic elements includes a tubular shell with a tubular, thin-wall fluid passage, which is set inside the said shell, and the edge of which, by an end plate, is airtight sealed with the edge of the said shell, in order to form an enclosed space between the inner wall of the said shell and the outer side of the said thin-wall fluid passage. And this enclosed space is vacuumed, filled with fluid medium. Heat eliminating fins are set in the said thin-wall fluid passage. There is a fluid suction core set inside the said enclosed space. There is an injection port, designed on the said end pale or on the said shell, which is used for vacuumizing or for filling of the said working fluid medium. This practical, new pattern applies the principle of heat transfer with heat pipe, using the heat radiation fins in the thin-wall fluid passage to form a space of heat elimination network. This new pattern adopts simple structure and has features of swift heat transfer and even heat conduction, easy-use and high reliability, and can be transformed to various types according to the electric components in different situation, to meet the requirements of different equipments.
