Heat pipe radiator integrated with heat transmission and heat radiation and manufacturing technology thereof

Abstract

The invention discloses a heat pipe radiator integrated with heat transmission and heat radiation and a manufacturing technology thereof. The heat pipe radiator adopts a long thin heat pipe with the pipe diameter of 2mm to 5mm; the long thin heat pipe is coiled in a spiral form; when the heat pipe radiator is in use, a part of each annular part of the heat pipe contacts with a heat source to form a heat absorbing section; other parts which do not contact with the heat source are used as heat-transmission heat-radiation sections; the heat transmission of heat pipe internal circulation of evaporation, condensation and backflow is formed in the annular heat pipe; the whole parts, which do not contact with the heat source, of the outer wall of the heat pipe directly radiate heat to air; therefore the heat transmission and the heat radiation are simultaneously realized; the whole heat pipe radiator is uniform in temperature, and can be bent into various shapes according to demands of the heat source, thereby being strong in adaptability; by the adoption of the long thin heat pipe which has the pipe diameter of 2mm to 5mm, and has better heat transmission and heat radiation effects than those of a heat pipe with a larger pipe diameter, the overall heat radiation efficiency of the heat pipe radiator is improved; the size and the weight of the radiator are decreased greatly.

Description

technical field [0001] The invention relates to a heat pipe radiator integrating heat transfer and heat dissipation and a manufacturing process thereof. Background technique [0002] Traditional heat pipes are usually used for heat conduction. One end of the heat pipe is in contact with the heat source, and the other end is connected to a heat sink such as an aluminum fin to transfer the heat from the heat source to the heat sink for heat dissipation. The heat dissipation area is directly proportional, so in order to improve the heat dissipation effect, it is usually necessary to configure a radiator with a large volume and weight, which increases the weight and volume of the heat dissipation product required, and the efficiency of heat conduction of the traditional heat pipe decreases with the increase of the length, so Conventional heat pipes are usually only capable of conducting heat over short distances. Contents of the invention [0003] In order to overcome the def...
