In order to improve the heat dissipation power and expand the applicable range of the heat sink, this paper combines the natural convection heat dissipation conditions and heat pipe technology to develop a new type of row heat pipe radiator, and conducts experimental research under natural convection cooling conditions in large space. . Through the research on the starting characteristics and the uniform temperature characteristics of the row heat pipe radiator at different input power and multi-angle, the heat dissipation performance of the developed new radiator is verified.
The development of row heat pipe radiators based on natural convection heat dissipation technology does not require moving parts, low cost and more reliable operation. Therefore, one of the purposes of this paper is to develop a device with the largest heat dissipation power under natural convection conditions. In view of this, a heat sink with a similar appearance to a common profile heat sink, which is actually based on heat pipe technology, is proposed.
The radiator is essentially a special-shaped heat pipe. The evaporation end of the heat pipe is the lower evaporation chamber, and the upper fin is the condensation end of the heat pipe, that is, each fin is hollow and communicates with the evaporation chamber. Row heat pipe radiator The whole radiator is made of copper, and its condensation end is composed of 13 heat pipe fins.
