Abstract

The invention discloses a multi-winding water-cooled inductor, and relates to the technical field of inductors. The multi-winding water-cooled inductor is characterized in that the multi-winding water-cooled inductor comprises a cylindrical magnetic core, wherein a frame for winding is arranged outside the magnetic core, multiple sets of coils are wound on the frame, the multiple sets of coils are wound from inside to outside to form a layered structure, a plurality of sub-coils are connected in series to form each set of coils, the multiple sets of coils are connected with one another in parallel, a water-cooled pipe for heat dissipation is arranged in the middle of each set of coils, an insulation cushion block is arranged between every two adjacent coils, and the water-cooled pipes of every two adjacent sets of coils are connected with each other through a connecting pipe. Each water-cooled pipe is arranged in the middle of the corresponding set of coils, and therefore the multi-winding water-cooled inductor has the better heat dissipation effect compared with traditional water-cooled heat dissipation; meanwhile, the multi-winding water-cooled inductor has the advantages of being high in safety level and capable of adapting to the high-temperature and humid environment.

Description

Many windings water-cooled inductor
Technical field
The present invention relates to inductors technique field, particularly relate to a kind of many windings water-cooled inductor.
Background technology
As everyone knows, inductor is to be the element that magnetic energy stores electric energy conversion.The structure of inductor is similar to transformer, but it only has a winding.Inductor has certain inductance, and it only stops the variation of electric current.If do not have electric current to pass through in inductor, it stops electric current to flow through it; If there is electric current to flow through it, when circuit disconnects it will to attempt to maintain electric current constant.Inductor claims again choke, reactor, dynamic reactor; At present, the heat dispersion of inductor is an important parameter that affects the inductor life-span, and the radiating mode of traditional inductor mainly contains air-cooled and water-cooled, but practice is found, the heat dispersion of traditional inductor is poor, not only causes the failure rate of inductor high, the life-span is short; Also cause energy resource consumption larger simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is: many windings water-cooled inductor that a kind of perfect heat-dissipating is provided.
The technical scheme that the present invention takes for the technical problem existing in solution known technology is:
A kind of many windings water-cooled inductor, comprise cylinder shape magnetic core, in the outside of described magnetic core, be provided with the framework of coiling use, on described framework, be wound with many group coils, described many group coils are layer structure coiling from inside to outside, and every group of coil is composed in series by a plurality of subcoils, between many group coils, be connected in parallel, in the centre of every group of coil, be provided with the water cooling tube of heat transmission, between adjacent windings, be provided with cross-over block, between the water cooling tube in adjacent windings, by tube connector, connect.
As optimal technical scheme, the present invention has also adopted following technical characterictic:
Described coil has three groups, and every group of coil is composed in series by ten subcoils.
Outer wall at described water-cooled inductor is provided with epoxy resin layer.
Described water cooling tube is copper pipe.
Advantage and good effect that the present invention has are: one, because the present invention is arranged at water cooling tube in the centre position of coil, therefore than traditional water-cooling, have better radiating effect; Two, because the coil in the present invention forms by organizing coils from parallel connection of coils more, between adjacent windings, be provided with cross-over block simultaneously, therefore increased the space between coil, improved air flow property, make it when carrying out water-cooled, also there is air-cooled function; Three, because the present invention is provided with epoxy resin layer at the outer wall of water-cooled inductor, therefore can improve on the one hand the safe class of water-cooled inductor, improve on the other hand the ability that water-cooled inductor adapts to high temperature, wet environment.

Wherein: 1, magnetic core; 2, coil; 3, cross-over block; 4, water cooling tube; 5, tube connector; 6, framework; 7, water cooling tube gateway; 8, epoxy resin layer; 9, inductor binding post.
Embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of many windings water-cooled inductor, comprises cylinder shape magnetic core 1, is provided with the framework 6 of coiling use in the outside of magnetic core 1, is wound with many group coils 2 on framework 6, and described many group coils 2 are layer structure coiling from inside to outside; As shown in Figure 1: every group of coil 2 is composed in series by a plurality of subcoils, organize between coil 2 more and be connected in parallel, in the centre of every group of coil 2, be provided with the water cooling tube 4 of heat transmission, between adjacent windings 2, be provided with cross-over block 3; Between water cooling tube 4 in adjacent windings 2, by tube connector 5, connect.
As optimal technical scheme, the coil 2 in above-mentioned specific embodiment has three groups, and every group of coil is composed in series by ten subcoils.In order to improve the safe class of water-cooled inductor, improve on the other hand the ability that water-cooled inductor adapts to high temperature, wet environment, this specific embodiment is provided with epoxy resin layer 8 at the outer wall of water-cooled inductor.
Water cooling tube 5 selects the good material of heat conductivility to make, and is generally preferably copper pipe.
The experimentation of this specific embodiment is, outside lead is connected with inductor binding post 9, outer loop water pipe is connected with water cooling tube gateway 7 simultaneously; Any of two water cooling tube gateways 7 can be used as cold water inlet in theory, another one is as hot water outlet, but, as preferably: as shown in Figure 2, cold water inlet is selected the water cooling tube gateway 7 of top (top in figure), hot water outlet is selected the water cooling tube gateway 7 of below (below in figure), and cold water can directly enter into the coil place of water-cooled inductor innermost layer like this, and then the heat energy that water-cooled inductor temperature is exceeded is most taken out of rapidly.
Above embodiments of the invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve, within all should still belonging to patent covering scope of the present invention.
