Be provided with the accommodation space that is used to hold magnetic core in the described drum stand, at least one side of drum stand is provided with and is used for the slot that fin inserts, and the opening direction of slot is drum stand dorsad.
Described drum stand comprises upper cover body and lower cover, and the upper cover body both sides relative with lower cover are respectively arranged with the accommodation space that is used to hold magnetic core.
Upper cover body is respectively arranged with in two relative sides and is used for the slot that fin inserts.
Upper cover body offers the louvre that is used to dispel the heat respectively in two relative sides, and louvre passes accommodation space, communicates with the ducted body of drum stand.
Upper cover body is provided with the slot that is used for the fin insertion away from that surface of lower cover.
Lower cover is respectively arranged with in two relative sides and is used for the slot that fin inserts.
Lower cover offers the louvre that is used to dispel the heat respectively in two relative sides, and louvre passes accommodation space, communicates with the ducted body of drum stand.
Lower cover is provided with the slot that is used for the fin insertion away from that surface of upper cover body.
Described magnetic core is " mouth " word shape.
Described winding comprises elementary winding and secondary winding, and elementary winding and secondary winding winding are on the relative both sides of drum stand.
The beneficial effects of the utility model are: drum stand of the present utility model is that plastics high temperature resistant, good heat dissipation effect are made; the heat-conductive characteristic of drum stand is good; and be provided with slot in each side; insert radiating fin in the slot, adopt the radiating mode of computer CPU, transformer is dispelled the heat; the heat that transformer produces in time can be distributed; have the advantage timely of dispelling the heat, protected transformer, prolonged the useful life of transformer.
