Abstract

Claims (35)

1. A vapor chamber, comprising:

a housing comprising a first cover plate and a second cover plate, wherein the first cover plate and the second cover plate are connected and define a sealed cavity;

a cooling medium;

a capillary structure disposed in the sealed cavity; and

a supporting structure extending from an inner surface of the housing into an internal space of the housing;

wherein a material of the first cover plate and the second cover plate is a high-strength composite material, wherein the high-strength composite material comprises a first material layer and a second material layer, wherein the strength of the first material layer is higher than the strength of the second material layer, a material of the first material layer is stainless steel, titanium, titanium alloy, tungsten, tungsten alloy, chromium, or chromium alloy, a material of the second material layer is copper or copper alloy, and wherein the second material layer is located on an inner side of the housing and separates the first material layer from the cooling medium; and

wherein a material of an inner core of the supporting structure is the material of the first material layer, and a material of a periphery of the supporting structure is the material of the second material layer.

2. The vapor chamber according to claim 1 , wherein the supporting structure abuts against the first cover plate and the second cover plate.

3. The vapor chamber according to claim 1 , wherein the supporting structure abuts against the capillary structure.

4. The vapor chamber according to claim 1 , wherein the supporting structure and the housing are an integrated structure, and wherein the supporting structure comprises a plurality of protruding points arranged in an array.

5. The vapor chamber according to claim 1 , wherein the second material layer of the first cover plate and the second material layer of the second cover plate enclose the sealed cavity.

6. The vapor chamber according to claim 1 , wherein the capillary structure is a porous metallic medium.

7. The vapor chamber according to claim 6 , wherein the capillary structure is one of copper mesh, copper fiber, copper powder, or foamy copper.

8. The vapor chamber according to claim 1 , wherein the capillary structure is disposed on the second material layer of the first cover plate.

9. The vapor chamber according to claim 1 , wherein the capillary structure is disposed on the second material layer of the first cover plate and the second cover plate.

10. A mobile terminal, comprising:

a middle frame;

a display screen;

a circuit board;

a battery; and

a vapor chamber;

wherein a through-hole extends in the middle frame, and the vapor chamber is embedded in the through-hole, and the vapor chamber and the middle frame jointly bear the display screen, the circuit board, and the battery; and

wherein the vapor chamber comprises:

a housing including a first cover plate and a second cover plate, wherein the first cover plate and the second cover plate are connected to form a sealed cavity chamber;

a cooling medium;

a capillary structure disposed in the sealed chamber; and

a supporting structure extending from an inner surface of the housing into an internal space of the housing;

wherein a material of the first cover plate and the second cover plate is a high-strength composite material, wherein the high-strength composite material comprises a first material layer and a second material layer, wherein the strength of the first material layer is higher than the strength of the second material layer, a material of the first material layer is stainless steel, titanium, titanium alloy, tungsten, tungsten alloy, chromium, or chromium alloy, and a material of the second material layer is copper or copper alloy, and wherein the second material layer is located on an inner side of the housing and separates the first material layer from the cooling medium; and

wherein a material of an inner core of the supporting structure is the material of the first material layer, and a material of a periphery of the supporting structure is the material of the second material layer.

11. The mobile terminal according to claim 10 , wherein a connection manner of the vapor chamber and the middle frame comprises one of riveting, bonding, welding, lapping, or metal over-molding.

12. The mobile terminal according to claim 10 , wherein the battery and the display screen are disposed on two sides of the vapor chamber in parallel respectively, and wherein the vapor chamber further comprises a battery surface facing towards the battery and a display surface facing towards the display screen, wherein the display screen and the display surface are parallel without contact.

13. The mobile terminal according to claim 10 , wherein the supporting structure abuts against the first cover plate and the second cover plate.

14. The mobile terminal according to claim 10 , wherein the supporting structure and the housing are an integrated structure, and wherein the supporting structure is a plurality of protruding points arranged in an array.

15. The mobile terminal according to claim 10 , wherein the capillary structure is a porous metallic medium.

16. The mobile terminal according to claim 14 , wherein the capillary structure is one of copper mesh, copper fiber, copper powder, or foamy copper.
