Abstract
A heat pipe (10) includes a main body (12), an inner layer (16), a chamber (13) and working material (18). The main body is made of metallic material having a high heat-transfer coefficient. The chamber is surrounded by the inner layer, and is substantially a vacuum. The working material is sealed in the chamber. The inner layer is fixed to an inner surface of the main body. The inner layer is inert to the working material, and isolates the working material from the main body. Furthermore, the working material readily globularizes when it is in contact with the inner layer.
Claims17
A heat pipe comprising:
- a main body made of metallic material having great heat transfer capability;
- an inner layer fixed to an inner surface of the main body and defining a sealed chamber therein;
- and
- working material sealed in the chamber;
- wherein the inner layer is inert to the working material and isolates the working material from the main body, and wherein the working material readily globularizes when it is in contact with the inner layer.
A heat pipe assembly comprising:
- a chassis adapted to abut against a heat generating device;
- a plurality of heat pipes arranged in a matrix manner, each of said heat pipes including:
- a tube-like main body made of metallic material having great heat transfer capability;
- an inner layer applied to an inner surface of the main body and defining a chamber therein;
- and
- working material circulated in the chamber;
- wherein
- one end of the main body is in contact with the chassis.
