Abstract
The utility model relates to a coil former. A column wall of the coil former is provided with a plurality of openings and the plurality of openings are arranged in a symmetrical mode. A cooling ventilating duct is formed by the plurality of openings. According to the coil former, dissipation and heating of a coil and a magnetic core can be effectively driven out for emitting through the ventilating duct, and a transformer and inductance can avoid too high temperature rise.
Description
Technical field
The utility model relates to electronic component, relates in particular to a kind of coil rack.
Background technology
At the encapsulation skeleton that uses traditional transformer or inductance, the heating that coil and core loss cause relies on the thermal radiation of device surface fully or leaves according to heat conducting mode, so cause whole device hot polymerization collection loss to strengthen, even cause that whole device worsens and greatly shorten useful life.
Employing strengthens specification increase coiling sectional area or selects the low high-grade magnetic core of loss or select large specification magnetic core, needs increase material cost and increasing to take the veneer space, thereby causes the unnecessary waste of resource.Therefore, how to provide a kind of heating of coil and core loss is derived effectively to distribute, improving the temperature rise of transformer and inductance too high is technical issues that need to address.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of coil rack.
The utility model provides a kind of coil rack, is on the post jamb of skeleton to be symmetrical arranged a plurality of perforates, and described a plurality of perforates form the air duct of heat radiation.
Coil rack provided by the utility model is effectively derived the heating of coil and core loss by air duct and to be distributed, and has avoided transformer or inductance temperature rise too high.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use among the embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of the utility model coil rack.
Fig. 2 is the structure chart after the utility model coil rack is mounted to voltage device/inductor.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Be illustrated in figure 1 as the schematic diagram of coil rack.Be on the post jamb 1 of these coil 30 skeletons 10 and be symmetrical arranged a plurality of perforates 2, the air duct 40 of described a plurality of perforates 2 formation heat radiations.Skeleton 10 adopts preferably material of thermosetting, and the wall thickness of post jamb 1 is thin as best one can, and mesopore is large as much as possible simultaneously to support fixed coil 30, and to form larger air duct 40, the heat energy diffusion of being convenient to magnetic core 20 and coil 30 is come.
Be illustrated in figure 2 as the structure chart after coil rack is mounted to voltage device/inductor.In figure (a), coil 30 is wound on the skeleton 10, and the air duct 40 of skeleton 10 is arranged at the air port of voltage device/inductor, perhaps is arranged at the position of fan of transformer/inductor.In figure (b), air duct 40 be arranged in parallel with the air port of described transformer or inductor, and such as air inlet 50 and air outlet 60, perhaps air duct 40 be arranged in parallel with the fan of described transformer or inductor.
In the present embodiment, behind the assembling assembling magnetic core 20, select the mounting means of corresponding device in conjunction with air port or position of fan in transformer or the inductor design, allow device air duct 40 aim at air port or the parallel by force heat dissipation design of employing fan of complete machine.
Coil rack provided by the utility model is effectively derived the heating of coil and core loss by air duct and to be distributed, and has avoided transformer or inductance temperature rise too high.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model embodiment.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation of the spirit or scope that do not break away from the utility model embodiment, realize in other embodiments.Therefore, the utility model embodiment will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
It below only is the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; all within the spirit and principle of the utility model embodiment; any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the utility model embodiment.
