Manufacturing method of heat pipe

Abstract

A heat pipe includes a sealed hollow casing, a wick structure lining an inner surface of the casing and a working medium contained in an interior of the casing. The casing includes an elongated main body having an elongated opening extending axially in the main body and a transparent cover fixed onto the main body and sealing the opening of the main body. The wick structure is provided by only lining an inner surface of the main body of the casing.

Description

technical field [0001] The invention relates to a heat pipe, in particular to a heat pipe whose working state of the internal working fluid can be visualized and its manufacturing method. Background technique [0002] At present, heat pipes have been widely used in the heat dissipation of electronic components with large heat generation. The heat pipe usually includes a shell, a capillary structure attached to the inner surface of the shell, and a working fluid with a low boiling point filled in the shell. The housing includes an evaporation section and a condensation section located at opposite ends. When working, the heat pipe uses the internal working fluid of the shell to absorb the heat generated by the heating electronic components in the evaporation section, then evaporates and vaporizes, moves to the condensation section with heat, and releases the heat through liquefaction and condensation in the condensation section. The liquefied work Under the action of the cap...

Problems solved by technology

[0003] The shell of the heat pipe is usually made of metal materials with high thermal conductivity, such as copper, aluminum, etc., the shell is opaque, and the working process of the working fluid inside it cannot be directly observed visually, but can only be obtained theoretically. It is not conducive to real-time observation and monitoring of the working status of the heat pipe.
