Heat dissipation structure

A heat dissipation structure, comprising:

• a heat dissipation member;
• and
• a fixed member, wherein the fixed member has a first surface and a second surface that are opposite to each other, the heat dissipation member is disposed on the first surface, and at least one part of the second surface corresponds to one side of at least one heat generating source and is disposed adjacent to the one side of the at least one heat generating source;
• wherein, the first surface has a first zone and a second zone, the second zone surrounds the first zone, the heat dissipation member is disposed on the first zone, and the first zone corresponds to the at least one heat generating source;
• wherein the second zone has at least one groove, and the at least one groove is arranged around at least one part of the first zone;
• wherein a distance between one side of the at least one groove that is adjacent to the first zone and the first zone is less than 1.0 mm, and a ratio of a volume of the at least one groove to a volume of the heat dissipation member is 0.9 to 1.6.
