1. A heat dissipation structure, comprising:
a heat dissipation unit; and
a fixation unit having a bottom and a wall, wherein the bottom and the wall jointly define a hollow area;
wherein one part of the heat dissipation unit is disposed on the fixation unit;
wherein the fixation unit is surroundingly arranged on a periphery of a heat source;
wherein the hollow area includes a first non-masking area, a second non-masking area, and a masking area, the masking area corresponds to another part of the heat dissipation unit, and the first non-masking area and the second non-masking area are arranged on opposite sides of the masking area;
wherein the first non-masking area has a first volume, the second non-masking area has a second volume, the first volume is equal to or not equal to the second volume, and a sum of the first volume and the second volume is at least greater than a predetermined volume change of the heat dissipation unit,
wherein a ratio of the sum of the first volume and the second volume to a volume of the heat dissipation unit is at least greater than 0.05.
