Loop gravity assisted heat pipe

Abstract

The invention relates to the technical field of heat transmission equipment, in particular to a loop gravity assisted heat pipe. The loop gravity assisted heat pipe comprises an evaporator, a condenser, a first pipeline, a second pipeline and a one-way liquid guide structure, and the condenser is located above the evaporator; one end of the first pipeline is communicated with a steam outlet of the evaporator, and the other end is communicated with a steam inlet of the condenser; one end of the second pipeline is communicated with a liquid outlet of the condenser, and the other end is communicated with a liquid inlet of the evaporator; the one-way liquid guide structure is arranged on the second pipeline and is suitable for conducting liquid in a one-way mode. According to the loop gravity assisted heat pipe, the one-way liquid guide structure only allows liquid to pass through and does not allow steam to pass through, the steam is prevented from flowing towards the condenser through the second pipeline, the flowing direction of the steam and the liquid is limited, and even under the conditions of the beginning of starting work and the low heat source load, the steam can be recycled. And normal starting of the loop gravity assisted heat pipe can be guaranteed, and the starting speed of the loop gravity assisted heat pipe is increased.

Description

technical field [0001] The invention relates to the technical field of heat transmission equipment, in particular to a loop gravity heat pipe. Background technique [0002] As a heat transfer structure, the heat pipe has high heat transfer efficiency. The heat pipe mainly relies on the vapor-liquid phase change heat transfer of the working liquid inside. It has small thermal resistance and high thermal conductivity, which can reach many times that of silver, copper, aluminum and other metals. Gravity heat pipe is a kind of heat pipe, which mainly relies on the potential energy difference of gravity to realize the return of liquid cooling inside the heat pipe. [0003] As a kind of gravity heat pipe, the loop gravity heat pipe includes an evaporator, a steam pipeline, a condenser and a liquid pipeline connected in sequence to form a heat transfer channel for gas-liquid working medium circulation. However, when the loop gravity heat pipe starts to work, it is easy for the in...
