Description

Separated gravity assisted heat pipe system with liquid storage tank

Technical Field

The utility model relates to the technical field of heat dissipation, in particular to a separated gravity assisted heat pipe system with a liquid storage tank.

Background

The gravity heat pipe is a heat pipe which takes gravity as the reflux driving force of a liquid working medium. The principle of the separated gravity heat pipe is the same as that of the common gravity heat pipe, and the structural difference is as follows: the condensation end and the evaporation end of the separated gravity heat pipe are two independent parts, namely a condenser and an evaporator.

The amount of working medium in the condenser and evaporator affects the heat transfer efficiency and operational stability of the heat pipe. When the liquid is too little, the liquid in the evaporator is less in proportion, the working medium in the evaporator is insufficient, and the vaporization heat absorption efficiency is reduced. When the liquid is too much, the liquid in the condenser accounts for more, the liquefaction efficiency of the gaseous working medium in the condenser is reduced, and the heat dissipation efficiency of the condenser is reduced.

During installation, the amount of working medium needs to be accurately controlled to ensure the optimal working performance of the heat pipe. Even if the working medium quantity is accurately filled, the distribution of the gas-liquid two-phase working medium in the condenser or the evaporator can be changed due to unstable working conditions, and the stable heat exchange performance of the heat pipe is affected because the liquid-gas distribution is not in an optimal state.

Even if the working medium is accurately filled, the working condition of the heat pipe is stable, but a small amount of leakage may occur in the use process of the heat pipe, and after long-term use, the working medium is reduced enough to influence the normal work of the heat pipe, and the working medium needs to be supplemented in time. Since the amount of the working medium remaining in the heat pipe is not well determined, the replenishment amount is also difficult to control when replenishing the working medium. The original working medium is often required to be discharged and then is completely refilled. Causing waste of the working medium.
