[0037] Specifically, the groups of heat dissipation fins 21 on the same side of the reactor oil tank 1 are arranged in a linear type, so that the overall size of the reactor is reduced, facilitating the overall transportation of the reactor and the installation of the reactor in a space-limited use environment, and improving the space utilization rate.

[0045] Specifically, in order to ensure the firmness of the connection, two angle steels 7 (fixed parts) are selected to be connected to the bottom oil guide pipes of the heat dissipation fin groups 2 on both sides of the reactor oil tank 1, and bolts and nuts are used for connection and fixation, so that the heat dissipation fin groups 2 are fixed together with the angle steels 7, thereby increasing the overall stability of the heat dissipation fin groups 2 on the same side; a bent angle steel 8 (or an I-beam) is selected to be fixed to one end of the bottom angle steel 7 of the heat dissipation fin group 2, and the other end is welded to the bottom support pad 9 of the reactor oil tank 1; the connection between the bent angle steel 8 or the I-beam (connecting part) in the support of the radiator 2 and the support pad 9 at the bottom of the reactor oil tank 1 is reinforced and enhanced by welding a second reinforcing rib plate 10.
