Heat dissipation plate and method for manufacturing the same

A heat dissipation device, comprising:

• a first plate including
• a first plurality of angled grooves arranged in a first direction and extending between a first longitudinal side and a second longitudinal side of the heat dissipation device, the second longitudinal side being opposite the first longitudinal side, and the first plurality of angled grooves disposed at a first inclination with reference to the horizontal, and
• a first longitudinal groove arranged in a longitudinal direction at the first longitudinal side and in fluid contact with the first plurality of angled grooves;
• a second plate including
• a second plurality of angled grooves arranged in a second direction and extending between the first longitudinal side and the second longitudinal side of the heat dissipation device, the second plurality of angled grooves disposed at a second inclination with reference to the horizontal, the second inclination being opposite to the first inclination, and
• a second longitudinal groove arranged in the longitudinal direction at the second longitudinal side and in fluid contact with the second plurality of angled grooves,
• wherein
• the second plate is coupled to the first plate,
• the first longitudinal side and the second longitudinal side are opposite longitudinal sides of the heat dissipation device,
• at least portions of the first plurality of angled grooves and the second plurality of angled grooves are connected to each other such that the first plurality of angled grooves and the second plurality of angled grooves define a fluid channel of the heat dissipation device, and
• the fluid channel includes coolant;
• and
• at least one capillary structure, wherein at least a portion of the fluid channel is covered by the at least one capillary structure.
