Modular composite-type pulsating heat pipe

Abstract

The invention provides a modular composite-type pulsating heat pipe comprising pulsating heat pipe bodies. Each pulsating heat pipe body is divided into a condensing section, an insulating section andan evaporation section, and each pulsating heat pipe body is a pulsating heat pipe module. The modular composite-type pulsating heat pipe is characterized in that buckles used for connecting every two pulsating heat pipe bodies are further arranged, and the two or more pulsating heat pipe modules constitute the modular composite-type pulsating heat pipe. The modular composite-type pulsating heatpipe invention has the advantages of that the application operating temperature range is wide, the heat dissipation ability is improved, and the design cost and production cost of manufacturers are reduced.

Description

technical field [0001] The invention relates to the fields of microelectronic devices and high-efficiency heat dissipation, in particular to a modular composite pulsating heat pipe. Background technique [0002] A pulsating heat pipe is a promising electronic device cooler. The pulsating heat pipe in the prior art is a two-phase heat transfer device with simple structure but complex mechanism. It vacuumizes a long capillary and then fills the inside of the capillary with liquid. If the diameter of the capillary is small enough, there will be intermittent When one end of the pulsating heat pipe is heated, the liquid evaporates and vaporizes, and the steam flows to the other end under a small pressure difference to release heat and condense into a liquid. Small tube diameter and repeated bending of hot and cold ends are the two basic conditions for forming a pulsating heat pipe, which transfers heat through phase change and vapor-liquid pulsation. Compared with ordinary heat...

Problems solved by technology

[0003] Although the pulsating heat pipes in the prior art have the above-mentioned advantages, there are still many defects that cannot be ignored, such as: the pulsating heat pipe can only work in a small temperature range, and requires different sizes and heat dissipation on different electronic devices. So far, no pulsating heat pipe with high heat dissipation efficiency and wide operating temperature range has been found, which limits its working capacity, is prone to dry-out, or difficult to start problems, as well as design and manufacturing costs. increasing problem
