Temperature plate and heat dissipation device

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.
