The invention discloses a heat pipe heat dissipation device based on air pressure driving. The heat pipe heat dissipation device comprises a heat conduction pipe and an air guide pipe. The heat conduction pipe is provided with an evaporation section and a condensation section which are mutually connected; the heat conduction pipe is provided with a containing cavity, the containing cavity extends to the evaporation section from the condensation section, and a working medium is contained in the containing cavity; the heat conduction pipe is provided with a capillary structure; the air guide pipe is arranged in the containing cavity and provided with a first channel, a second channel is arranged between the air guide pipe and the heat conduction pipe, and part of or all the capillary structures are arranged in the second channel. An inlet of the gas guide pipe communicates with the first channel and the evaporation section, an outlet of the gas guide pipe communicates with the first channel and the condensation section, and the gas guide pipe is provided with a one-way gas guide device. Physical separation of gas-liquid two-phase flow paths is achieved, and shear resistance generated by gas-liquid reverse flow in a traditional heat pipe is eliminated. And stable working medium circulation and heat transfer performance can be maintained in the horizontal direction and under the working condition along the gravity, and the applicability of the heat exchanger in various installation postures is effectively expanded.

This invention discloses an improved multi-stage ultra-long gravity heat pipe, belonging to the technical field of ultra-long gravity heat pipes. The improved multi-stage ultra-long gravity heat pipe includes a heat pipe body, a support mechanism fixedly installed on the outer side of the heat pipe body, several steam pools fixedly installed on one side of the inner wall of the heat pipe body, and several two-phase flow mechanisms fixedly installed on the other side of the inner wall of the heat pipe body. A return liquid pipe extending into the two-phase flow mechanism is fixedly installed inside the heat pipe body. Each of the two-phase flow mechanisms includes a buffer pool and an overflow pipe. One side of the bottom of the buffer pool is fixedly connected to the top of the overflow pipe, and the bottom of the buffer pool has several open liquid tanks. By setting up two-phase flow mechanisms, the working fluid return is achieved by gravity, requiring no external power input. The heat transfer coefficient is higher than that of copper, and groundwater is not extracted, avoiding geological subsidence, brine scaling, water resource consumption, and the phenomenon of decreased or even failed heat transfer performance.
