One-way loop type pulsating heat pipe and energy saving device

Abstract

The invention relates to a pulsating heat pipe, in particular to a one-way loop type pulsating heat pipe. The one-way loop type pulsating heat pipe comprises a pulsating heat pipe body, and the pulsating heat pipe body is a closed cycle pipe device. An upper end pipeline of a pipeline of the pulsating heat pipe body is in a wave shape, and a lower end pipeline of the pipeline of the pulsating heatpipe body is in a linear shape. The pulsating heat pipe body comprises a condensation section, a heat insulation section and an evaporation section. The upper end of the pipeline of the pulsating heat pipe body is the condensation section, the middle of the pipeline of the pulsation heat pipe body is the heat insulation section, and the lower end of the pipeline of the pulsation heat pipe body isthe evaporation section. A U-shaped bend is designed at the evaporation section, and condensate forms effective liquid seal at the U-shaped bend to avoid the occurrence of back flow, so that stable one-way flow is formed in the pulsating heat pipe body, and the heat transfer performance of the pulsating heat pipe body is effectively improved.

Description

Technical field [0001] The invention relates to a pulsating heat pipe, in particular to a one-way loop type pulsating heat pipe. Background technique [0002] With the advancement of electronic technology, the volume of electronic components is getting smaller and smaller, the degree of integration is getting higher and higher, and the power consumption is getting larger. Obviously, traditional natural convection or forced convection heat dissipation can no longer meet the needs of electronic technology development, and there is an urgent need to develop a new type of heat transfer device that is small, light, strong heat dissipation capability, and low-cost. The pulsating heat pipe can be widely used in the field of electronic component cooling as an efficient heat conducting element. The loop-type pulsating heat pipe applied to the solar collector can collect approximately 62% of the solar energy, which is equivalent to the efficiency of the traditional expensive heat pipe sys...
