Description
Technical field
The utility model relates to a kind of capacitor, specifically a kind of heat radiation type capacitor.
Background technique
Capacitor is a kind of device for accommodating charge, is one of biggish component of usage amount in electronic equipment, answers extensively
It for the separated by direct communication in circuit, couples, bypasses, filtering, resonant tank, energy conversion, control etc..Capacitor is in reality
Biggish heat is easily issued in use, if not in time evacuated heat, it is breakdown to will lead to capacitor, causes entire circuit paralysis
Paralysis.
Canned body outside existing capacitor, usually solid construction, the heat of capacitor can only first be transmitted to canned
Body distributes outward again, and heat dissipation effect is limited.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of heat radiation type capacitor, heat exchange effect compared with
It is good, promote the stability in capacitor operational process.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme:
A kind of heat radiation type capacitor, including capacitor body, capacitor body is equipped with electrode connection, outside capacitor body
Be arranged with packing colloid, the lower part of the packing colloid is equipped with lower side baffle, the downside baffle rings around the circle of packing colloid one and with
There is lower separate space, lower side baffle is equipped with lower air holes, and the top of packing colloid is equipped with upper between the outer surface of the packing colloid
Side baffle, the upside baffle rings enclose around packing colloid one and have upper separate space, upside between the outer surface of the packing colloid
Baffle is equipped with upper air holes, and the inside of packing colloid is equipped with air duct, packing colloid be equipped be connected to air duct into hole and portal.
Hot pilot hole is additionally provided in the packing colloid, this is thermally conductive to extend to capacitor body surface, another to hole one end
End is connected to air duct.
The hot pilot hole is at least arranged one.
It is described it is upper between separate space and it is lower between the width of separate space be 3-10 millimeters.
It is described into hole and portalling for round hole.
The utility model improves the convection current performance of air, ventilates more smooth, and heat exchange effect is preferable, promotes electricity
Stability in container operational process.
Detailed description of the invention
Attached drawing 1 is the utility model section structural schematic diagram.
Specific embodiment
For the feature, technological means and specific purposes achieved, function that can further appreciate that the utility model, below
The utility model is described in further detail in conjunction with attached drawing and specific embodiment.
As shown in Fig. 1, the utility model discloses a kind of heat radiation type capacitor, including capacitor body 12, capacitor
Ontology 12 is equipped with electrode connection 1, is arranged with packing colloid 13 outside capacitor body 12, the lower part of the packing colloid 13 is equipped with
Lower side baffle 2, the lower side baffle 2 enclose around packing colloid 13 1 and have lower interval between the outer surface of the packing colloid 13
Chamber 4, lower side baffle 2 are equipped with lower air holes 3, and the top of packing colloid 13 is equipped with upper side baffle 10, and side baffle 10 is around envelope on this
It fills the circle of colloid 13 1 and there is upper separate space 11 between the outer surface of the packing colloid 13, upper side baffle 10 is equipped with upper air holes
9, the inside of packing colloid 13 is equipped with air duct 6, packing colloid 13 be equipped be connected to air duct 6 into hole 5 and portal 8.Packaging plastic
Body 13 is usually the canned straight forming of epoxide resin material.Upper side baffle and lower side baffle can be directly with packing colloid using same
Material be integrally formed.Sunk using cold air, the principle that hot-air rises, through lower air holes and upper air holes, the increase of orientation is empty
The Convective of gas, thus take away heat by gas, the temperature on surface when reducing capacitor work.Into hole and portal for circle
Hole.
In addition, be additionally provided with hot pilot hole 7 in the packing colloid 13, this is thermally conductive to extend to capacitor body to 7 one end of hole
12 surfaces, the other end are connected to air duct 6.The heat that capacitor body generates when working, is directly transmitted to air duct through hot pilot hole
In, then be discharged through air duct, accelerate distributing for heat.
The hot pilot hole is at least arranged one.
It is described it is upper between separate space and it is lower between the width of separate space be 3-10 millimeters.
In the utility model, the heat that capacitor generates when running can be transmitted to packing colloid, and a part is through hot pilot hole
It is directly delivered in air duct, perhaps also into hole or can be portalled into Kong Liudong cold air from portalling for air duct and enter air duct
In, it is taken out of to be exchanged with the heat formation in air duct, directly the heat inside reduction packing colloid, better heat-radiation effect.Also
Some gas through lower air holes enter down between in separate space, exchanged with the heat on packing colloid surface, thus to packing colloid
Surface carries out distributing cooling.Equally, upper air holes has had air disengaging flowing, convenient for distributing cooling.Pass through air duct, hot pilot hole
Directly to the cooling that distributes inside packing colloid, air holes, lower air holes promote the flowing of air to packing colloid surface in cooperation
Cooling, better heat-radiation effect.
It should be noted that it is practical new to be not limited to this above is only the preferred embodiment of the utility model
Type, although the utility model is described in detail referring to embodiment, for those skilled in the art, still
It can modify to technical solution documented by previous embodiment or equivalent replacement of some of the technical features,
But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the protection scope of the utility model.
