Abstract
The utility model discloses a transformer with a heat dissipation function. The transformer comprises a coil frame where coils are wound, a magnetic core arranged in a central through hole of the coil frame, a spiral insulating mat which wraps the magnetic core and is fixed in the through hole of the coil frame, and a clamping piece arranged on the spiral insulating mat and clamped on the coil frame.
Description
Technical field
An electric equipment, particularly a kind of transformer.
Background technology
According to the transformer of prior art, mainly there is such form: primary coil and secondary coil are sequentially wrapped on single coil frame, and core is attached to bobbin by the through hole of bobbin.For fear of electric leakage or other accidents, conventionally can between magnetic core and bobbin, insulation cushion be set, but magnetic core can generate heat at work, impels the aging of insulation cushion, reduce the useful life of transformer, prior art is unresolved such problem also.
Utility model content
For solving the deficiencies in the prior art, the heat that provides a kind of magnetic core that can shed to produce is provided the purpose of this utility model, slows down insulation cushion aging, and the heat that the design of bobbin is also beneficial to coil generation sheds, and slows down coil aging, thereby has extended the life-span of transformer.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A transformer for heat radiation, comprising: the bobbin of winding around, be placed in the magnetic core in bobbin central through hole, and parcel magnetic core is also fixed on the spiral insulation cushion in bobbin through hole; Be located at spiral insulation cushion and be connected in the shackle member of bobbin.
The transformer of aforesaid a kind of heat radiation, forms spirality gas-permeable channels between spiral insulation cushion and magnetic core, bobbin.
The transformer of aforesaid a kind of heat radiation, shackle member is clamping projection.
The transformer of aforesaid a kind of heat radiation, bobbin is provided with the limited impression corresponding to clamping projection.
The transformer of aforesaid a kind of heat radiation, bobbin forms to be had: a plurality of bobbin supports, be formed at the ventilative space of support between bobbin support, be placed in the coil standing groove on bobbin support, be placed in the ventilative groove in bobbin through hole.
The transformer of aforesaid a kind of heat radiation, is formed with ventilative gap between ventilative groove and insulation cushion.
The transformer of aforesaid a kind of heat radiation, insulation cushion is rubber blanket.
Usefulness of the present utility model is: the heat that the utility model provides a kind of magnetic core that can shed to produce, slow down insulation cushion aging, and the heat that the design of bobbin is also beneficial to coil generation sheds, and slows down coil aging, thereby has extended the life-span of transformer.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of a kind of embodiment of the present utility model;
Fig. 2 is the vertical section figure of a kind of embodiment of the present utility model;
The implication of Reference numeral in figure:
1 bobbin, 101 bobbin supports, the 102 supports space of breathing freely, 103 coil standing grooves, 104 ventilative grooves, 2 magnetic cores, 3 spiral insulation cushions, 301 spirality gas-permeable channels, 302 clampings projections, 4 ventilative gaps.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
A transformer for heat radiation, comprising: the bobbin 1 of winding around, be placed in the magnetic core 2 in bobbin 1 central through hole, and parcel magnetic core 2 is also fixed on the spiral insulation cushion 3 in bobbin 1 through hole; As a kind of preferred, insulation cushion selects cost low, and has the rubber blanket of certain deformability; Be located at spiral insulation cushion 3 and be connected in the shackle member of bobbin 1, preferably shackle member is clamping projection 302 as a kind of, and bobbin 1 is provided with the limited impression corresponding to clamping projection 302.Between spiral insulation cushion 3 and magnetic core 2, bobbin 1, form spirality gas-permeable channels 301.Such gas-permeable channels is not only communicated with left and right and is also communicated with up and down, thereby the heat that magnetic core 2 is distributed obtains Quick diffusing.
Bobbin 1 forms to be had: a plurality of bobbin supports 101, be formed at the ventilative space 102 of support between bobbin support 101, and be placed in the coil standing groove 103 on bobbin support 101, be placed in the ventilative groove 104 in bobbin 1 through hole; Between ventilative groove 104 and insulation cushion, be formed with ventilative gap 4.Such design makes the heat producing in coil running can not remain on bobbin 1, but by support space 102 heat that sheds of breathing freely, and such design makes the heat of magnetic core 2 also can pass through spirality gas-permeable channels 301, be communicated to ventilative gap 4, by the ventilative space 102 of support, distributed; Thereby such design is all circulated the air of the upper and lower four direction in left and right, fast and effectively by the dissipation of heat of magnetic core 2 and coil generation.
The heat that the utility model provides a kind of magnetic core 2 that can shed to produce, slows down insulation cushion aging, and the heat that the design of bobbin 1 is also beneficial to coil generation sheds, and slows down coil aging, thereby has extended the life-span of transformer.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection range of the present utility model.
