Abstract
In metal tubes for heat pipes and a method of manufacturing the metal tubes, a metal tube includes a tube defining an inner space, and at least one dividing portion extruding from an inner sidewall of the metal tube. The at least one dividing portion divides the inner space into a vapor channel and a liquid channel connected to the vapor channel. The metal tubes can prevent heat pipe form being dried out and improve heat dissipation efficiency of heat pipes.
Claims15
A metal tube for heat pipes, comprising:
- a tube defining an inner space;
- at least one dividing portion extruding from an inner sidewall,
- wherein the at least one dividing portion divides the inner space into a vapor channel and a liquid channel connected to the vapor channel.
A method of manufacturing a metal tube for heat pipes, comprising:
- a) providing a tube, a number of dividing portions extruding from an inner sidewall of the tube;
- b) applying a pressure onto the dividing portions using a tool such that end surfaces thereof are adjoined with each other thereby defining a vapor channel and a liquid channel in an inner space of the tube.
