Heat efficiency lifting method for filling-storing type liquid filling rate-variable heat pipe and device

Abstract

The invention provides a heat efficiency lifting method for a filling-storing type liquid filling rate-variable heat pipe. The heat efficiency lifting method is characterized in that the liquid filling rate of the heat pipe is adjusted by changing the flowing amount of a working medium in the heat pipe, and the purpose of improving the heat efficiency of the heat pipe is achieved. The invention further provides a liquid filling rate-variable heat pipe device in another technical scheme. According to the liquid filling rate-variable heat pipe device, under the condition that an inner cavity structure, the use volume, the heat exchange area and the working medium composition of an original heat pipe are unchanged, the filling amount inside the heat pipe is changed through the mode by which the working medium of the heat pipe is recovered in a working medium storage device in a liquid state and reused, so that the liquid filling rate is changed, the working medium is taken and dischargedconveniently, fast and adjustably so as to adapt to various working conditions in real time, the energy-saving benefit is remarkable, and a wide market application prospect is achieved.

Description

technical field [0001] The invention relates to a technical method and a device for improving the thermal efficiency of a heat pipe, and belongs to the technical field of engineering energy. Background technique [0002] In the contemporary social environment, the problem of energy depletion has seriously hindered the rapid development of the economy and society. As a highly efficient element for enhanced heat transfer, heat pipes are widely used in high-end electronic equipment, HVAC, power, metallurgy, glass, chemical industry, light industry , ceramics and other fields. Under certain working conditions, the liquid filling rate of the heat pipe has a significant impact on the thermal efficiency. Existing heat pipe products cannot make corresponding adjustments to the annual working conditions after the working medium is charged. Another variable heat conduction heat pipe uses non-condensable gas to change the effective volume and heat exchange area of ​​the heat pipe to ...

Existing heat pipe products cannot be adjusted accordingly for the annual working conditions after the working fluid is charged

Another variable heat conduction heat pipe uses non-condensable gas to change the effective volume and heat exchange area of ​​the heat pipe to adjust the heat conduction performance to keep the temperature of the hot end constant. During use, the charge amount remains unchanged, but the operation is complicated and the control is difficult. Big
