Heat pipe radiator adopting novel phase change materials

Abstract

The invention provides a heat pipe radiator adopting novel phase change materials. The heat pipe radiator is characterized by comprising square heat pipe shells, heat radiation cylinders, cylindrical shell heat pipes, a base plate and novel phase change sponges; the number of the square heat pipe shells is two, and the square heat pipe shells are fixed to the two ends of the base plate through the cylindrical shell heat pipes correspondingly; left-end gaps and right-end gaps are formed in the base plate, the novel phase change sponges are arranged in the left-end gaps and the right-end gaps, and upper-end gaps are formed in the upper end of the base plate; the heat radiation cylinders are fixedly arranged at the upper ends of the square heat pipe shells; key grooves are formed in the upper ends of the heat radiation cylinders; and heat radiation is carried out by adopting a method of filling of the novel phase change materials, the novel hard carbon nanotube sponges are used as the phase change materials through filling, the novel hard carbon nanotube sponges can continuously absorb water vapor in air at normal temperature, when the temperature of cooling fins rises to a certain temperature, water in the sponges can evaporate to absorb heat, and therefore the aim of high-temperature heat radiation is achieved.

Description

technical field [0001] The invention relates to the field of radiator heat dissipation, in particular to a heat pipe radiator using a new phase change material. Background technique [0002] The radiator is mainly used in the heat dissipation of CPU and high-heat-generating equipment, and dissipates the heat generated by the equipment into the air. This requires the radiator to have a good thermal conductivity. The current mainstream radiators are heat pipe radiators and integrated water cooling. There are two types of radiators. A heat pipe is an artificial component with excellent heat transfer properties. The main body of a commonly used heat pipe is a closed metal tube, often made of copper, with a small amount of working medium and capillary structure inside, and the inside of the tube is in a vacuum state. The working principle of the heat pipe radiator is that the CPU generates heat, and the heat is conducted to the heat pipe. The working medium in the heat pipe is h...
