Electronic radiator assembly equipped with arc cross section and used at vertical position

The invention discloses an electronic radiator assembly equipped with an arc cross section and used at a vertical position. A radiator comprises a basic body and peripheral fins. The cross section of the basic body is in an arc shape. The fins comprise a first fin and second fins. The first fin outwardly extends from the midpoint of the arc shape along the direction vertical to the arc shape. The second fins outwardly extend from a plane where the arc shape is located. Multiple second fins outwardly extending from the first fin are in parallel with the second fins extending in the same direction. An isosceles triangle is formed on the extended end portions of the first fin and the second fins. The vertex angle of the isosceles triangle is a right angle. Two radiators are abutted against each other through the isosceles triangles. The vertex angles of the isosceles triangles of the two radiators are connected at a point and one base angle of the isosceles triangle of one radiator and one base angle of the isosceles triangle of the other radiator are connected at another point. Thus, the base angles, connected at a point, of the isosceles triangles of the two radiators form a right angle in order that the electronic radiator assembly dissipates heat of an electronic element with vertical structure so as to save installation space while satisfying heat dissipation efficiency.
