Accompanying drawing explanation
For more clearly illustrating structural feature of the present utility model and effect, it is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the 6.6KW changer that this utility model embodiment provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present utility model rather than whole embodiment.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained on the premise of not making creative work, all should belong to the scope of this utility model protection.
As it is shown in figure 1, the 6.6KW changer 10 of this utility model embodiment includes heat-radiating substrate 11, inductance 13 and inductance isolation shell 12.Wherein, inductance isolation shell 12 is arranged on heat-radiating substrate 11, and inductance 13 is located at the inside of inductance isolation shell 12.6.6KW changer 10 includes but not limited to that for ac/dc 6.6KW changer, inductance 13 includes but not limited to as PFC inductance.Should be understood that 6.6KW changer 10 the most also includes other power devices and structural member, but in the present embodiment for sake of simplicity, only with include heat-radiating substrate 11, inductance 13 and inductance isolation shell 12 6.6KW changer 10 as description object.
As it is shown in figure 1, inductance isolation shell 12 is the housing of one end open, inductance 13 loads in inductance isolation shell 12 from described opening.Inductance isolation shell 12 has diapire 123, and diapire 123 is relative with described opening.Screwed hole 121 is offered, equipped with screw (not shown) in screwed hole 121, to be fixed on heat-radiating substrate 11 by diapire 123 on diapire 123.In the present embodiment, make the mode being screwed, and the periphery of diapire 123 offers 4 screwed holes 121；In other embodiments, it is possible to use other modes fix diapire 123, thus inductance are isolated shell 12 and is arranged on heat-radiating substrate 11.
The inductance 13 installed in inductance isolation shell 12 is heating power device, and it can produce amount of heat when being energized work.The heat that inductance 13 produces will be radiated on inductance isolation shell 12, and conduct to heat-radiating substrate 11 via inductance isolation shell 12.In order to strengthen the heat conductivility of inductance isolation shell 12, between inductance isolation shell 12 and heat-radiating substrate 11, i.e. between diapire 123 and heat-radiating substrate 11, lay the first heat-conducting layer (not shown).In the present embodiment, described first heat-conducting layer is thermal conductive silicon glue-line.In other embodiments, it is possible to use other Heat Conduction Materials form described first heat-conducting layer.
Posting an insulating barrier (not shown) on the inwall of inductance isolation shell 12, described insulating barrier is between inwall and the inductance 13 of inductance isolation shell 12.Described insulating barrier discharges for preventing inductance 13 with the inwall of inductance isolation shell 12, strikes sparks.In the present embodiment, described insulating barrier is made up of insulating paper；In other embodiments, described insulating barrier can use other insulant.
The inside of inductance isolation shell 12, is filled with the second heat-conducting layer (not shown) between inwall and the inductance 13 of inductance isolation shell 12, and described second heat-conducting layer can strengthen the heat-conduction effect between inductance isolation shell 12 and inductance 13.In the present embodiment, described second heat-conducting layer is made up of heat conductive silica gel；In other embodiments, it is possible to use other Heat Conduction Materials.
