Claims

[Scope of utility model registration request]

(1) A radiator consisting of a plurality of heat radiating panels is connected to the main body of the electrical equipment, and a group of multiple radiators are arranged in parallel, and a cooling fan is arranged at the side edge of the group of radiators. An air-cooled oil-filled electrical device characterized in that an air inlet is formed between the outermost heat radiating panels of the radiator group.

(2) Utility model registration claim No. 2, characterized in that the air inlet is an air duct whose inner side is shaped so that it can be inserted into the gap between the heat radiating panels, and whose outer side is formed into a trumpet shape that is larger than the gap between the heat radiating panels. Air-cooled oil-filled electrical equipment described in item 1).

(3) The air-cooled oil-filled electrical equipment according to claim 1, wherein the air inlet is formed by an air guide plate installed between heat radiation panels.
