Abstract
The utility model discloses a novel transformer easy to dissipate heat, which is characterized by comprising a skeleton, a magnetic core, a primary coil, a secondary coil, a heat conduction device and a sleeve cover, wherein the magnetic core is embedded into the skeleton and is fixed; the primary coil and the secondary coil are respectively wound on the skeleton and are overlapped layer by layer; the heat conduction device is embedded in the primary coil; the top of the sleeve cover is provided with two openings; and the openings are communicated with a cavity. The novel transformer has the beneficial effects that not only can the transformer have a good heat dissipation effect and the service life of the transformer is prolonged, but also copper wires can be properly reduced, resources are saved, the groove width can also be properly reduced and the volume of the product can also be reduced.
Description
Technical field
The utility model relates to the transformer technology field, relates in particular to a kind of novel transformer of easy heat radiation.
Background technology
Electronic transformer is placed among social now each electronic product, as is used among the electronic products such as panel computer, LCD TV, mobile phone and notebook computer.Be a very important factor useful life of the life-span of electronic transformer to electronic product.In order to make transformer action better and prolong its useful life, in the design transformer, how the designer could let the radiating effect of transformer good if just must considering.
See that from the electronic transformer design point of view line of the enamelled wire that primary coil is used footpath is generally thinner, cause that primary coil voltage is high, electric current is low; And the line of secondary coil footpath is bigger than primary coil line footpath; Cause secondary current high, inner being prone to of line bag generates heat, and is difficult for heat radiation; Coil is expanded cause the line bag to become fat, influence transformer operate as normal and useful life.In order to make good heat dissipation effect, design principle now is that winding slot is widened, so that line bag radiating effect is better.This design but makes bobbin widen, and consumption of natural resource will be more, and internal heat is distributed but not have fundamentally and solved.
Summary of the invention
The purpose of the utility model is to provide to the deficiency of prior art existence a kind of novel transformer of easy heat radiation.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of novel transformer of easy heat radiation is characterized in that: it comprises skeleton, magnetic core, primary coil, secondary coil, heat-transfer device and upper shield, and said magnetic core embeds skeleton and fixing; Said primary coil and secondary coil are wound on the skeleton respectively, and folded mutually layer by layer; Heat-transfer device is embedded in the secondary coil; Said cover tops has two openings, and is connected with chamber.
The beneficial effect of the utility model is: not only can make the good heat dissipation effect of transformer, prolong the useful life of transformer, and copper cash can suitably reduce, and economize on resources, groove width also can suitably diminish, and small product size is reduced.

Fig. 2 is the finished figure of transformer shown in Figure 1;
Wherein, description of reference numerals is following:
1-1~magnetic core; 1-2~upper shield; 1-3~heat-transfer device;
1-4~secondary coil; 1-5~primary coil; 1-6~skeleton.
[embodiment]
To combine accompanying drawing to come the utility model is done further to specify below:
Like Fig. 1, shown in 2, a kind of novel transformer of easy heat radiation is characterized in that: it comprises skeleton 1-6, magnetic core 1-1, primary coil 1-5, secondary coil 1-4, heat-transfer device 1-3 and upper shield 1-2, and said magnetic core 1-1 embeds skeleton 1-6 and fixing; Said primary coil 1-5 and secondary coil 1-4 are wound in respectively on the skeleton 1-6, and folded mutually layer by layer; Said heat-transfer device 1-3 is embedded in the secondary coil 1-4; Said upper shield 1-2 top has two openings, and is connected with chamber, the heat that be used to dispel the heat this transformer 1-5 and secondary coil 1-4 are produced.
Like Fig. 1, shown in 2, the material of said skeleton 1-6 and upper shield 1-2 itself can be selected the high material of thermal conductivity ratio bakelite for use, to increase the whole heat-sinking capability of transformer.By the utilization of high heat-conducting, it is faster that the heat that transformer 1-5 and secondary coil 1-4 are produced will distribute.
