Abstract
The invention discloses a compound-type efficient heat pipe and a technology. The heat pipe is a heat transfer element with a very high heat-conducting property, a gravity-assisted heat pipe has a superior heat conduction effect, while the earth gravity has a great influence on the use of the gravity-assisted heat pipe in some situations, a pulsating heat pipe can relatively well solve the problem of the influence of the gravity. However, due to the fact that the pulsating heat pipe has a capillary structure, the ultra thin external diameter in the structure causes difficulty in connecting a heat conduction structure. The compound-type heat pipe which combines the advantages of the gravity-assisted heat pipe and the pulsating heat pipe is produced, and can be applied in important heat conduction situations. According to the compound-type efficient heat pipe and the technology, several vertical or U-shape folded semi-finished pulsating heat pipes are uniformly added and arranged in the inner diameter of the shell of a sheared gravity-assisted heat pipe, vacuum pumping and liquid adding are conducted in sequence according to a heat pipe processing technique, then the pulsating heat pipes are encapsulated into a compound heat pipe so as to form the efficient compound-type efficient heat pipe which is safe and reliable and has a certain antigravity feature.
