Abstract
The invention discloses a radiator type transformer, comprising an aluminum base, a primary coil and a heat conducting filling body, wherein the aluminum base comprises a central column and an outer ring, a groove is formed between the central column and the outer ring, the primary coil sleeves the central column and is accommodated in the groove, the heat conducting filling body covers the surface of the primary coil and full fills the groove, and the aluminum base is internally provided with a cooling liquid channel. The radiator type transformer disclosed by the invention has good heat dissipating effect since the surface of the primary coil is covered with the heat conducting filling body and the cooling liquid channel is formed at the bottom of the aluminum base.
Description
Technical field
The present invention relates to a kind of heat-dissipating voltage transformer, belong to transformer technology field.
Background technology
Generally do high-power transformer with EI type transformer in prior art, that enamelled wire is wound on skeleton, again silicon steel sheet is inserted the EI type transformer that skeleton is formed, structurally, due to silicon steel sheet scale, overall volume is large for EI type transformer, affect the installing space of product and the weight of product, use due to EI type structure, so iron loss and copper loss are comparatively large, leakage field large, cause that transformer efficiency is low, temperature rise, noise be large.
A kind of iron core that adopts is also had not crack the toroidal transformer of gap, adopt silicon steel sheet winding shaping, wrap insulate layer again, after formed around enamelled wire, iron core do not crack gap toroidal transformer structurally, silicon-steel sheet used for iron core winding shaping does not crack gap, without bag screen between primary winding and secondary winding, use because iron core does not crack gap reason, so after transformer energising, inrush current increases instantaneously, transformer and external connected electronic components and parts are easily damaged, also has transformer in use due to voltage fluctuation, easily make transformer magnetic saturation, and cause transformer to generate heat until burn.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of heat-dissipating voltage transformer, by primary coil Surface coating conductive filler body and arrange bottom aluminum base liquid cooling passage improve radiating effect.
The present invention adopts technical scheme as follows:
A kind of heat-dissipating voltage transformer, comprise aluminum base, primary coil and conductive filler body, described aluminum base comprises newel and outer shroud, groove is formed between described newel and outer shroud, described primary coil is sheathed on described newel and is contained in described groove, full described groove is also filled in the coated described primary coil surface of described conductive filler body, is also provided with cooling passage in described aluminum base.
Described aluminum base is provided with gap, and described aluminum base is divided into two parts independent of each other by described gap, and these two parts are connected by wire.
Described transformer also comprises wire, and described newel is provided with multiple first wire guide, is equipped with multiple second wire guide outside described, and described wire connects described first wire guide and described second wire guide, forms secondary coil.
Compared with prior art, beneficial effect of the present invention is: heat-dissipating voltage transformer of the present invention passes through at primary coil Surface coating conductive filler body, heat-conducting area increases, utilize conductive filler body to transfer heat to aluminum base to distribute in time, radiating effect significantly improves, and be also provided with cooling passage bottom described aluminum base, walk heat by the fluxion strap of cooling fluid, improve the radiating effect of transformer further.
Accompanying drawing explanation
Figure 1 shows that structural representation of the present invention.
Embodiment
Embodiment:
