## Abstract

A method for enclosing a heat pipe with metal is disclosed. The method includes the steps of: a) providing a tube made of a metal; b) putting the heat pipe in a hollow of the tube; and c) stretching the tube to shrink an inner diameter of the tube for tightly enclosing the heat pipe.

## Claims

### Claim 1

A method for enclosing a heat pipe with metal, comprising the steps of:
a) providing a tube made of a metal;
b) putting the heat pipe in a hollow of the tube; and
c) stretching the tube to shrink an inner diameter of the tube for tightly enclosing the heat pipe.

### Claim 2 (depends on 1)

The method of claim 1, further comprising the step of:
d) bunging an end of the tube with a metal plug after step c).

### Claim 3 (depends on 1)

The method of claim 1, wherein the metal is aluminum.
