Further, the partial size of the quartz sand is 80-120 mesh.
Further, the aluminium box is cube shaped frame 5-15mm bigger than transformer body maximum outer dimension, and institute
State cube shaped frame top open wide, bottom be equipped with mounting bracket.
The transformer body is replaced with inductor body by a kind of heat radiating type inductor.
The utility model has the advantage that
The utility model provides a kind of heat radiating type transformer, inductor, not only effectively increases thermal coefficient, reduces
The temperature rise of transformer, and radiate uniformly, good heat conduction effect.
Detailed description of the invention
Fig. 1 is heat radiating type transformer, inductor structure schematic cross-sectional view in the utility model；
Fig. 2 is heat radiating type transformer, another schematic cross-sectional view of inductor structure in the utility model.
The reference numerals are as follows:
1, aluminium box；2, heat-conducting glue layer；3, quartz sand layer；4, transformer body or inductor body.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.

Transformer body or inductor body 4 and heat dissipating layer in aluminium box；Heat dissipating layer includes heat-conducting glue layer 2 and quartz sand layer 3, is led
Hot glue layer and the alternate encapsulating of quartz sand layer are between transformer body or inductor body and the gap of aluminium box.
Heat-conducting glue layer with a thickness of 8-12mm.The component and constituent content of heat-conducting glue layer are as follows: epoxide-resin glue 98-99%, Gu
Agent 1-2%, curing agent are alicyclic ring amine hardener or polyamide curing agent.Quartz sand layer with a thickness of 4-6mm.Quartz sand layer is
Purity quartzite, SiO2Content be greater than or equal to 99-99.5%, Fe2O3Content be less than or equal to 0.005%；The grain of quartz sand
Diameter is 80-120 mesh.Aluminium box is cube shaped frame 5-15mm bigger than transformer body or inductor body maximum outer dimension,
And the top of cube shaped frame is opened wide, bottom is equipped with mounting bracket.
Heat radiating type transformer, inductor in the embodiments of the present invention replace encapsulating using heat-conducting glue and quartz sand
Mode, between transformer body or inductor body and the gap of aluminium box formed heat-conducting glue layer and quartz sand layer it is alternate dissipate
Thermosphere.After the thermally conductive adhesive curing haveing excellent performance, thermal coefficient is generally 1.1 ~ 1.5 W/m K, though and the thermal coefficient of quartz sand
It is related to the density of the distribution of its particle, the mode of landfill and landfill, but all close to 10 W/m K, and the fusing point of quartz sand
It is 1750 DEG C.Therefore, by the way of heat-conducting glue layer and quartz sand layer encapsulating, the thermal coefficient of heat dissipating layer is effectively raised,
