Description
Technical field
The utility model relates to capacitor technology field, particularly relates to a kind of capacitor heat sink.
Background technology
Capacitor, being usually called for short its ability holding electric charge is electric capacity, represents by letter C.Definition 1: capacitor, as the term suggests being ' container of dress electricity ', is a kind of device holding electric charge.English name: capacitor.Capacitor is one of a large amount of electronic component used in electronic equipment, be widely used in circuit every straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.Definition 2: capacitor, any two insulated from each other and all form a capacitor between the conductor (comprising wire) of being separated by very near.
Electric capacity is different from capacitor.Electric capacity is fundamental physical quantity, symbol C, and unit is F (farad).
The special formula of general formula C=Q/U plane-parallel capacitor: electric field strength E=U/d between plate, condenser capacitance determines formula C=ε S/4 π kd
Along with making rapid progress of electronic information technology, the update speed goes of digital electronic goods is fast, based on the consumer electronics product volume of production and marketing sustainable growth of the products such as panel TV (LCD and PDP), notebook computer, digital camera, capacitor industry has been driven to increase.And having driven the development of associated materials, equipment Industry, China has become global capacitor big producing country.
In prior art, large-scale capacitor device, in the long-time process used, is easy to produce heat energy, is easy to produce self-destruction, thus causes other electronic devices and components around capacitor to be damaged by it, thus the resource of large losses and cost.
Utility model content
In view of this, be necessary to provide one can effective temperature-reducing, calm other electronic devices and components of protection be damaged, and economize on resources and the capacitor heat sink of cost.
The utility model realizes like this, a kind of capacitor heat sink, comprise capacitor case, also comprise metal protection layer and blower fan, described metal protection layer is wrapped in capacitor case outside, the cavity body of sealing is formed between described metal protection layer and capacitor case, the side of described metal protection layer is provided with fresh air inlet, opposite side is provided with exhaust vent, fresh air inlet and exhaust vent are all communicated with described cavity body, described fresh air inlet is located at the top of metal protection layer, exhaust vent is in the bottom of metal protection layer, the outer wall of described capacitor case is provided with multiple heat conduction thimble, described heat conduction thimble is evenly distributed on the shell of capacitor case, and outer wall wall that is vertical and capacitor case, described assembling is on the outside of metal protection layer, and blower fan is communicated with described cavity body by fresh air inlet.
Further, described heat conduction thimble is the aluminium matter barred body of needle-like.
Further, described capacitor case and metal protection layer coaxial.
The advantage of a kind of capacitor heat sink that the utility model provides is: the utility model is simple and reasonable, by arranging metal protection layer and blower fan, described metal protection layer is wrapped in capacitor case outside, the cavity body of sealing is formed between described metal protection layer and capacitor case, the side of described metal protection layer is provided with fresh air inlet, opposite side is provided with exhaust vent, fresh air inlet and exhaust vent are all communicated with described cavity body, described fresh air inlet is located at the top of metal protection layer, exhaust vent is in the bottom of metal protection layer, the outer wall of described capacitor case is provided with multiple heat conduction thimble, described heat conduction thimble is evenly distributed on the shell of capacitor case, and outer wall wall that is vertical and capacitor case, described assembling is on the outside of metal protection layer, and blower fan is communicated with described cavity body by fresh air inlet, in the process used, the heat of capacitor internal is derived by heat conduction thimble, and accumulate in cavity body, the cold wind of outside blows in cavity body by blower fan, the heat be attached on heat conduction thimble is derived from exhaust vent, the temperature of effective reduction capacitor case inside, thus avoid capacitor to occur by the phenomenon of thermal explosion, thus protect other electronic devices and components and be not damaged, save ample resources and cost.
Accompanying drawing explanation
