Abstract

A thermal module includes a housing having multiple independent compartments not in communication with each other. Each compartment communicates with an open end of at least one heat pipe. The open end communicates with a heat pipe chamber in the heat pipe, whereby the independent compartments communicate with the heat pipe chambers.

Claims

1. A thermal module comprising a housing having multiple independent compartments not in communication with each other, each compartment communicating with an open end of at least one heat pipe, the open end communicating with a heat pipe chamber in the heat pipe, whereby the independent compartments communicate with the heat pipe chambers.

2. The thermal module as claimed in claim 1, wherein the independent compartments have equal or unequal capacities.

12. The thermal module as claimed in claim 1, wherein the independent compartments have equal or unequal capacities.

3. A thermal module comprising:

a housing having multiple independent compartments not in communication with each other, each compartment containing therein a working fluid; and

multiple independent first heat pipes, each first heat pipe being connected with one of the independent compartments, each first heat pipe having a first open end and a first closed end opposite to the first open end, the first heat pipe defining a first heat pipe chamber therein in communication with the first open end, the first open end and the first heat pipe chamber communicating with the compartment, wherein vapor-liquid circulations of the working fluids contained in the independent compartments independently take place within the independent compartments and the first heat pipe chambers to transfer heat.

4. The thermal module as claimed in claim 3, further comprising multiple independent second heat pipes, each second heat pipe being connected with one of the independent compartments, each second heat pipe having a second open end and a second closed end opposite to the second open end, the second heat pipe defining a second heat pipe chamber therein in communication with the second open end, the second open end and the second heat pipe chamber communicating with the compartment, whereby vapor-liquid circulations of the working fluids contained in the independent compartments independently take place within the independent compartments and the second heat pipe chambers to transfer heat.

5. The thermal module as claimed in claim 3, wherein at least one partitioning board is disposed between the independent compartments, whereby the independent compartments are isolated from each other in horizontal direction.

6. The thermal module as claimed in claim 3, wherein the first heat pipes are circular heat pipes, flat-plate heat pipes, D-shaped heat pipes or semicircular heat pipes.

7. The thermal module as claimed in claim 4, wherein the second heat pipes are circular heat pipes, flat-plate heat pipes, D-shaped heat pipes or semicircular heat pipes.

8. The thermal module as claimed in claim 3, wherein the housing has a top section and a bottom section, the independent compartments being positioned between the top section and the bottom section and isolated from each other in horizontal direction.

9. The thermal module as claimed in claim 8, wherein one face of the top section serves as a top face of the independent compartments and one face of the bottom section serves as a bottom face of the independent compartments, the other face of the bottom section being a heat contact face.

10. The thermal module as claimed in claim 3, wherein the housing is formed with multiple perforations in communication with the independent compartments respectively, the first open ends of the first heat pipes being connected to the perforations respectively.

11. The thermal module as claimed in claim 4, wherein the housing is formed with multiple perforations in communication with the independent compartments respectively, the first open ends of the first heat pipes and the second open ends of the second heat pipes being connected to the perforations respectively.
