Claim 16:
17. The circuit board of claim 1, wherein:
the circuit board is disposed in a heat-dissipation air duct;
the circuit board comprises a first edge and a second edge both in parallel with a direction from an air inlet of the heat-dissipation air duct to an air outlet of the heat-dissipation air duct;
the plurality of heat-generating components are distributed in rows between the first edge and the second edge;
the rows comprise a first row and a second row;
the first row and the second row are closer to the first edge than the second edge;
the first row is closer to the first edge than the second row; and
in a working state, an average temperature of heat-generating components of the first row excluding a first heat-generating component closest to the air inlet of the heat-dissipation air duct among the first row is smaller than an average temperature of heat-generating components of the second row excluding a different first heat-generating component closest to the air inlet of the heat-dissipation air duct among the second row.
