摘要： A computational heat dissipation structure includes a circuit board including a plurality of heating components; and a radiator provided corresponding to the circuit board; wherein a space between the adjacent heating components is negatively correlated with heat dissipation efficiency of a region where the adjacent heating components are located. The computing device of the disclosure includes a device housing enclosing an enclosed heat-dissipation air duct, and the computational heat dissipation structure; the computational heat dissipation structure is located in the enclosed heat-dissipation air duct. Since the space between the adjacent heating components of the disclosure is negatively correlated with the heat dissipation efficiency of the region where the adjacent heating components are located, i.e., the higher the heat dissipation efficiency of the region where the adjacent heating components are located is, the smaller the space between the adjacent heating components in the region will be, the heat dissipation efficiencies of the heating components are balanced, and load of a fan is reduced. Therefore, the mine provided by the disclosure avoids the problem of overheating damage of the heating components even if a large number of computing devices are gathered in the same space.
