Abstract
The invention discloses a capacitor outer shell with good heat dissipation performance. The capacitor outer shell with the good heat dissipation performance comprises a shell and a base, wherein the shell and the base are arranged coaxially, the shell is provided with an upper opening, the base is arranged on the bottom of the shell, the size of the upper surface of the base is larger than that of the lower surface of the shell, mounting holes are formed in the positions, close to corners, on the base, multiple stand columns with small ends up and big ends down are arranged in the shell, the stand columns are provided with external threads, a heat dissipation groove is formed in the position, making contact with the shell, of the upper surface of the base, the size of the heat dissipation groove is smaller than that of the lower surface of the shell, the heat dissipation groove is filled with heat dissipation materials, and multiple through holes are formed in the lower surface of the shell. The capacitor outer shell with the good heat dissipation performance is installed to and connected to equipment through the base, the mounting holes mainly facilitate installation, the stand columns with small ends up and big ends down are arranged in the shell for fixing the inner cores of a capacitor, the situation that capacitive performance is lowered due to mutual contact among the inner cores and contact between the inner cores and the shell is avoided effectively, the heat dissipation groove enables clearance to exist between the shell and the connected equipment, and heat dissipation is facilitated.
Description
Technical field
The present invention relates to a kind of shell of electric elements, relate in particular to the capacitor case that a kind of thermal diffusivity is good.
Background technology
Capacitor case is the requisite part of capacitor, but in assembling process due to present capacitor, capacitor is enclosed within aluminum hull, and capacitor in use generates heat, and aluminum hull can not well be dispelled the heat, and the problem of electric capacity explosion easily occurs.
The capacitor case of selling does not on the market have positioning function more, and inner core of capacitor is arranged on wherein, easily touches the inwall of shell, cause the security performance of product to reduce, cause product failure, also easily produce and rock, get loose because shakiness is installed, thereby affect the work of whole capacitor.
Summary of the invention
Object of the present invention is just to provide one to address the above problem, safe, and inner core is difficult for getting loose and rocks, and can freely not cause because of heat radiation the good capacitor case of thermal diffusivity of explosion.
To achieve these goals, the technical solution used in the present invention is such: the capacitor case that a kind of thermal diffusivity is good, comprise housing that coaxial setting and top are uncovered and the base of housing bottom, described base upper surface size is greater than housing lower surface size, and be provided with installing hole near edge on base, in described housing, be provided with several up-small and down-big columns, and column is provided with external screw thread, base upper surface and housing contact position are provided with radiating groove, described radiating groove size is less than housing lower surface size, and in radiating groove, be filled with heat sink material, housing lower surface is provided with several through holes.
As preferably: described column and through hole are all uniformly distributed in housing.
As preferably: described heat sink material is silica gel.
Compared with prior art, the invention has the advantages that: the housing of capacitor passes through base, realize and being connected with the installation of equipment, on base, be provided with installing hole near edge, mainly to be convenient to install, and in housing, be provided with several up-small and down-big columns, and column is provided with external screw thread, it is mainly the inner core of fixed capacitor, and effectively avoid being in contact with one another between inner core, and the situation of avoiding inner core to contact with housing causing capacitive property to reduce, base upper surface and housing contact position are provided with radiating groove, make the equipment room of housing and connection have space, be beneficial to heat radiation, and in radiating groove, be filled with heat sink material, housing lower surface is provided with several through holes, the heat that can effectively capacitor be produced passes to heat sink material by through hole, and there is heat sink material to dissipate, the present invention is simple in structure, convenient and practical.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1, housing; 2, base; 3, installing hole; 4, column; 5, heat sink material; 6, through hole.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1: referring to Fig. 1, the capacitor case that a kind of thermal diffusivity is good, comprise the base 2 of coaxial setting and top uncovered housing 1 and housing 1 bottom, described base 2 upper surface sizes are greater than housing 1 lower surface size, and be provided with installing hole 3 near edge on base 2, in described housing 1, be provided with several up-small and down-big columns 4, and column 4 is provided with external screw thread, base 2 upper surfaces and housing 1 contact position are provided with radiating groove, described radiating groove size is less than housing 1 lower surface size, and in radiating groove, be filled with heat sink material 5, housing 1 lower surface is provided with several through holes 6, described column 4 and through hole 6 are all uniformly distributed in housing 1, described heat sink material 5 is silica gel.
The housing 1 of capacitor is by base 2, realize and being connected with the installation of equipment, on base 2, be provided with installing hole 3 near edge, mainly to be convenient to install, and in housing 1, be provided with several up-small and down-big columns 4, and column 4 is provided with external screw thread, it is mainly the inner core of fixed capacitor, and effectively avoid being in contact with one another between inner core, and the situation of avoiding inner core to contact with housing 1 causing capacitive property to reduce, base 2 upper surfaces and housing 1 contact position are provided with radiating groove, make housing 1 have space with the equipment room being connected, be beneficial to heat radiation, and in radiating groove, be filled with heat sink material 5, housing 1 lower surface is provided with several through holes 6, the heat that can effectively capacitor be produced passes to heat sink material 5 by through hole 6, and there is heat sink material 5 to dissipate, column 4 and through hole 6 are all uniformly distributed in housing 1, be convenient to arrange inner core of capacitor, heat sink material 5 is silica gel, good heat dissipation effect.
