Temperature plate and heat dissipation device
A temperature plate includes a plate body and at least two supporters. The plate body has a first plate and a second plate, and a vacuum chamber is defined by the first plate and the second plate. The first plate has a first external surface, and the plate body is bent to form at least two bent portions with the first external surface being a compressive side, and the supporters are disposed inside the vacuum chamber and connected to an inner wall of the vacuum chamber to enhance a structural strength of the bent portions and also to improve heat conduction, wherein the temperature plate is combined with a cooling fin assembly, the cooling fin assembly is disposed on the first external surface. When the number of the bent portions are two, the configuration of the two bent portions allows the plate body to clip the cooling fin assembly.
1. A temperature plate, comprising:
a plate body comprising a first plate and a second plate, wherein a vacuum chamber is defined by the first plate and the second plate, the first plate has a first external surface, and the plate body is bent to form at least two bent portions with the first external surface being a compressive side; and
at least two supporters bent and disposed inside the vacuum chamber, located corresponding to the at least two bent portions and connected to an inner wall of the vacuum chamber to enhance a structural strength of the at least two bent portions and also to improve heat conduction, wherein the at least two supporters stop extending at flat portions of the plate body;
wherein the temperature plate is combined with a cooling fin assembly, the cooling fin assembly is disposed on the first external surface, the configuration of the at least two bent portions allows the plate body to clip the cooling fin assembly.
2. The temperature plate of claim 1 , wherein a curvature radius of the bent portion is at least twice of a thickness of the bent portion.
3. The temperature plate of claim 1 , wherein the at least two supporters are metal units.
4. The temperature plate of claim 1 , wherein the second plate has a second external surface, and the at least two supporters are between the first external surface and the second external surface.
5. The temperature plate of claim 1 , wherein the first plate and the second plate are two plate portions of a plate workpiece, and the plate workpiece is bent to form the two plate portions.
6. The temperature plate of claim 1 , wherein the first plate or the second plate has a plurality of protruding portions at the bent portion, the protruding portions construct the supporter, and the protruding portions are aligned or misaligned to each other.
7. The temperature plate of claim 1 , wherein one of the first plate and the second plate has a plurality of protruding portions at the bent portion, the other one of the first plate and the second plate has a plurality of recess portions at the bent portion, the protruding portions and the recess portions construct the supporter, and the protruding portions are aligned or misaligned to the recess portions.
