Method and device for improving thermal efficiency of a rechargeable heat pipe with variable liquid filling rate

Abstract

The invention provides a method for improving thermal efficiency of a rechargeable heat pipe with variable liquid filling rate, which is characterized in that the liquid filling rate of the heat pipe is adjusted by changing the flow rate of the working medium in the heat pipe to achieve the purpose of improving the thermal efficiency of the heat pipe. Another technical solution of the present invention is to provide a heat pipe device with variable liquid filling rate. This invention can change the heat pipe's internal cavity structure, use volume, heat exchange area and working fluid composition without changing the original heat pipe cavity structure. The working fluid is recovered in a liquid state in the working fluid storage device and reused, thereby changing the filling amount inside the heat pipe to change the liquid filling rate, making the pumping of the working fluid convenient and adjustable, and adapting to various working conditions in real time. The utility model has remarkable energy-saving benefits and has broad market application prospects.

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
