Heat will lead to case swells when the heat is excessive, until explosion, it follows that in order to improve the service life of capacitor and work
Make safety, it is necessary to effectively be radiated, and fan is set on the cabinet body of existing compensating electric capacity cabinet, made in cabinet body using fan
Air flow, heat is exported in time, but with the increase for using the time, the revolving speed of fan, air duct the originals such as blocking
Because can all lead to the decline of heat dissipation effect, so being badly in need of a kind of new structure that can effectively take away deep love.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provides and provided upwards using the fan of housing bottom
Air-flow and air duct a kind of compensating electric capacity for quickly taking away heat for being made up of the gap of the axial fin of shell outer rim
The external air duct type air-cooled structure of device.
The technical scheme adopted by the utility model is that:
A kind of external air duct type air-cooled structure of compensation capacitor, including end cap, shell and capacity cell, end cap spiral-lock is in shell
Pole plate is arranged in the insulation sleeve in end cap in body upper end, and the lower end which protrudes into shell is connect with the intracorporal capacity cell of shell,
It is characterized by: a fan storehouse is arranged in the housing bottom surface, setting and the homoaxial fan of shell, the fan in the fan storehouse
Air below fan storehouse can be sucked and be flowed up after the blowout of fan storehouse upper end along shell outer rim.
Further more, fan storehouse upper surface is embedded in the lower end of shell, the bottom surface of shell mounts a copper sheet, the copper sheet bottom surface
The fan is installed in one collection wind cabin of connection, the collection wind cabin bottom surface, and collection wind cabin outer rim is provided with guide duct, each guide duct and fan
One aperture of storehouse upper surface aligns.
Further more, the multiple fins of shell outer rim radial equipartition, the upper surface setting one in the fan storehouse between two fins
A aperture.
Further more, multiple through-holes are arranged in fan orlop face.
Further more, the fan is sent into collection wind cabin after sucking air from through-hole, the guide duct of air from collection wind cabin outer rim is upward
It is flowed up after outside blowout to aperture along the gap between two fins.
The advantages and positive effects of the utility model are as follows:
In the utility model, shell outer rim is arranged radially the multiple and homoaxial fin of shell, shell lower end insertion one
In fan storehouse, copper sheet, collection wind cabin and fan are set gradually below housing bottom surface, multiple guide ducts are arranged in collection wind cabin outer rim, each
One aperture of the upward upper end of guide duct bending and fan storehouse upper surface aligns, and each aperture is placed exactly in two adjacent convex
Between rib.In use, fan rotates, air is sucked from the through-hole in fan orlop face, air is sent to collection wind cabin, at copper sheet
The heat for being conducted through the housing bottom surface come is taken away, and is then blown out outside fan storehouse by the guide duct of bending, aperture, air is along two
Gap between a fin flows up, and the air for flowing the heat of shell outer rim is taken away, and by guiding role, makes
The air on periphery flows and is filled into fan storehouse subjacent, thus forms quick circulation, is the safe and stable of capacitor
Operation provides good dissipating-heat environment.
