Description
Technical field
The present invention relates to capacitor accessory technical field, in particular, relate to a kind of metallic film capacitor heat radiation
Shell.
Background technology
Metallic film capacitor of the prior art, due to the deficiency of heat dispersion, causes inefficacy ratio higher, performance
Instability, the life-span is short.Its reason is that metallic film capacitor has certain heating power, and metallic film capacitor
Film thermal conductivity all poor, cause metallic film capacitor heating more serious, performance just cannot be guaranteed, and increase
The inefficacy ratio of thermal breakdown.In the prior art, in order to improve the job stability of metallic film capacitor, and gold is extended
In the service life of genusization thin film capacitor, mainly take to increase the method to increase equivalent area for the metallic film capacitor volume
The thermal resistance making thin film capacitor declines.But said method result in the rising of thin film capacitor manufacturing cost, and increases
Difficulty is fixed in the installation of thin film capacitor, have impact on the miniaturization of the equipment using metallic film capacitor.
Content of the invention
The technical problem to be solved is to provide a kind of metallic film capacitor heat-dissipating casing, and this shell is tied
Structure is simple, and good heat dissipation effect can effectively improve the heat dispersion of metallic film capacitor.
The technical problem to be solved realizes by the following technical solutions.
A kind of metallic film capacitor heat-dissipating casing, including outer cover body, is provided with metal inside described outer cover body
Changing thin film capacitor, described outer cover body top and bottom all have groove, are inserted with copper heat sink strip inside described groove,
Described copper heat sink strip is looped around outside metallic film capacitor, and described copper heat sink strip is provided with some heat absorbing sheets,
On described copper heat sink strip, lower end has been fixedly connected with heat sink.
Further, described heat absorbing sheet is positioned between copper heat sink strip and metallic film capacitor, described heat absorbing sheet
Scribble thermal grease with metallic film capacitor contact position.
Further, described heat sink is fixed by pin and outer cover body.
Staff can calculate the copper heat sink strip length of needs in advance according to the size of metallic film capacitor,
First copper heat sink strip is wrapped in metallic film capacitor surrounding, then heat absorbing sheet side is coated thermal grease is attached to metallization
On thin film capacitor, opposite side is fixed on copper heat sink strip, then the metallized film capacitor being wrapped copper heat sink strip
Device is put into inside outer cover body, by the pull-out of groove up and down from outer cover body for the upper and lower side of copper heat sink strip, solid with heat sink
It is set to one, finally by pin, heat sink and outer cover body are fixed.
Compared with the prior art, beneficial effects of the present invention is embodied in：
The present invention uses copper heat sink strip to dispel the heat, good heat dissipation effect, and cost is relatively low, and is convenient for changing, good in economic efficiency；Heat absorption
Piece and metallic film capacitor contact position scribble thermal grease, can strengthen endothermic effect, reduce metallized film capacitor
Device operating temperature；It is provided with upper and lower two heat sinks, can faster the heat within copper heat sink strip be distributed, improve and dissipate
Thermal effect.

Detailed description of the invention
In order to make invention realize technological means, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
It is specifically illustrating, the present invention is expanded on further.
As it is shown in figure 1, a kind of metallic film capacitor heat-dissipating casing, including outer cover body 1, outer cover body 1 is internal to be set
Having metallic film capacitor 6, outer cover body 1 top and bottom all have groove, are inserted with copper heat sink strip 5, copper inside groove
Heat sink strip 5 processed is looped around outside metallic film capacitor 6, and copper heat sink strip 5 is provided with some heat absorbing sheets 3, copper heat sink strip 5
Upper lower end has been fixedly connected with heat sink 2, and heat absorbing sheet 3 is positioned between copper heat sink strip 5 and metallic film capacitor 6, inhales
Backing 3 and metallic film capacitor 6 contact position scribble thermal grease, and heat sink 2 passes through pin 4 and outer cover body 1 is fixed.
The length of copper heat sink strip 5 can select according to concrete metallic film capacitor 6 size, first by copper
Heat sink strip 5 is wrapped in metallic film capacitor 6 surrounding, it is ensured that endothermic effect, then is placed in the heat absorbing sheet 3 scribbling thermal grease
Between copper heat sink strip 5 and metallic film capacitor 6, then the metallic film capacitor 6 being wrapped copper heat sink strip 5
Put into outer cover body 1 internal, by the pull-out of groove up and down from outer cover body 1 for the upper and lower side of copper heat sink strip 5, with heat sink 2
It is fixed as one, finally by pin 4, heat sink 2 and outer cover body 1 is fixed, when needing to change copper heat sink strip 5, only need to tear open
Unload heat sink 2, take out metallic film capacitor 6, the copper heat sink strip 5 more renewing.
The general principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel are it should be appreciated that the present invention is not restricted to the described embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
