Vapor chamber
A vapor chamber includes a main body. The main body includes a base plate and a top plate. The base plate includes a plate body, a peripheral frame and a plurality of supporting pillars. The plate body has a surface. The peripheral frame is disposed on the surface of the plate body. The surface and the peripheral frame together define a first space. The first space is configured to accommodate a working fluid. The supporting pillars are located in the first space and are distributed on the surface of the plate body. The supporting pillars, the plate body and the peripheral frame are of an integrally-formed structure. The top plate abuts against the peripheral frame and the supporting pillars to seal up the first space.
1. A vapor chamber, comprising:
a main body, comprising:
a base plate, comprising:
a plate body having a surface;
a peripheral frame disposed on the surface, the surface and the peripheral frame together defining a first space, the first space being configured to accommodate a working fluid; and
a plurality of supporting pillars located in the first space and distributed on the surface, the supporting pillars, the plate body and the peripheral frame being of an integrally-formed structure;
a top plate abutting against the peripheral frame and the supporting pillars to seal up the first space; and
wherein the peripheral frame has a gap communicated with the first space, the vapor chamber further comprises:
a liquid infusion tube having a first end and a second end opposite to the first end, the liquid infusion tube penetrates through the gap, the first end is located in the first space, the second end is exposed outside the main body; and
a plastic outer frame, comprising:
a first frame body surrounding to define a second space, the main body being at least partially located in the second space and abutting against the first frame body:
an encapsulating structure connected with an inner side of the first frame body, a portion of the liquid infusion tube exposed outside the main body being embedded inside the encapsulating structure; and
two second frame bodies separated from and opposite with each other,
the second frame bodies defining the second space therebetween and respectively connecting with the first frame body, the encapsulating structure connecting with one of the second frame bodies, each of the second frame bodies and the first frame body forming a stair structure.
2. The vapor chamber of claim 1 , wherein the main body has two first side surfaces opposite with each other and two second side surfaces opposite with each other, the first side surfaces and the second side surfaces are alternately disposed to surround the main body and abut against the first frame body, the second frame bodies respectively abut against a corresponding one of the first side surfaces and a portion of each of the second side surfaces, the second side surfaces are at least partially exposed outside the second frame bodies.
3. The vapor chamber of claim 1 , further comprising:
a first structural plate located in the first space and disposed on the surface, the first structural plate comprising a plurality of first capillary structures, the first capillary structures being located on a side of the first structural plate away from the surface; and
a second structural plate located in the first space and disposed on the top plate, the second structural plate comprising a plurality of second capillary structures, the second capillary structures being located on a side of the second structural plate facing to the surface.
