The utility model comprises a housing main body of which the front end and the back end are respectively fixedly provided with a front cover plate and a back cover plate, a radiating fan is connected with the front cover plate of the housing main body and the back cover plate is provided with air inlet holes. The adoption of the structure achieves the effects of reasonable structure and good radiation.

Description

A kind of electronic ballast shell with great heat radiation effect

Technical field:

The utility model relates to the energy-saving electric light source equipment technical field, refers in particular to a kind of electronic ballast shell with great heat radiation effect.

Background technology:

When the power of electric ballast surpasses 250 watt-hours, because present electronic circuit peak efficiency can only reach about 93%, also with regard to the time say that himself loss accounts for about 7% of input power, common 1000 watts electric ballast loss power is 70 watts, this part power that consumes will all be converted into heat, make electric ballast when work, exist too high temperature always, under such high temperature, electronic circuit is easy to break down, shorten life of product, and the structure of existing electric ballast mostly is directly to fix a loam cake with screw on the main body of ballast shell, and heat abstractor is not set, make the development of electric ballast technology be subjected to restricting significantly.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of rational in infrastructure, radiating effect electronic ballast shell preferably is provided.

For achieving the above object, the technical scheme that the utility model provides is:, include housing body, the front and back end of main body also is fixed with front shroud and back shroud respectively, is connected on the front shroud of housing body radiator fan is installed, and forms fresh air inlet on the back shroud.

In each half housing, be equipped with fixedly " L " type heating panel of heater element, and by elastic clip heater element and " L " type heating panel are clamped and to link together, be somebody's turn to do on the inwall of the one-body molded side plate therein of " L " type heating panel, form gas channel between heating panel and the side plate inwall, form the anti-skidding line of zigzag on the sidewall of " L " type heating panel.

Described housing body includes upper and lower two identical in structure half housings and forms, the two halves housing is installed the housing body that constitutes electric ballast mutually, horizontal expansion forms chute and connecting plate is installed respectively on the biside plate of half housing, the connecting plate cooperation of upper half-shell is inserted in the installation chute of housing lower half, and the cooperation of the connecting plate of housing lower half is inserted in the installation chute of upper half-shell.

The utility model is installed radiator fan on the front shroud of housing, form fresh air inlet on the back shroud.Therefore can reach better heat radiating effect, simultaneously heater element is fixed on and is molded over the housing body inwall on " L " type heating panel, make heat that heater element produces in time the gas channel between heating panel and side plate inwall take out of outside the housing by radiator fan, and this moment, fresh air inlet in time replenished the relative Cryogenic air in the external world.After the shell of electric ballast adopted this kind structure, its working temperature was the highest below 55 ℃.

Description of drawings:

Accompanying drawing 1 is equipped with the structural representation of half housing of front shroud for the utility model;

Accompanying drawing 2 is equipped with the structural representation of half housing of back shroud for the utility model;

Accompanying drawing 3 is the utility model elastic clip structural representation.

Embodiment:

Below in conjunction with a preferred embodiment and accompanying drawing thereof the utility model is described further,

See shown in accompanying drawing 1～accompanying drawing 3, this preferred embodiment includes upper and lower two identical in structure half housings, the two halves housing is installed the housing body that constitutes electric ballast mutually, the front and back end of main body also is fixed with front shroud 1 and back shroud 2 respectively, is connected on the front shroud 1 of housing body a radiator fan 3 is installed.Form fresh air inlet 4 on the back shroud 2.In each half housing, be equipped with fixedly " L " type heating panel 6 of heater element 5, and heater element 5 and clamping are linked together by elastic clip 7, be somebody's turn to do on the inwall of " L " type heating panel 6 one-body molded side plates therein, form gas channel 8 between " L " type heating panel 6 and this side plate inwall, the heat that heater element 5 produces can be taken out of outside the shell by radiator fan 3 with gas channel 8, fresh air inlet 4 is in time mended the relative Cryogenic air in the external world in the housing simultaneously, form the anti-skidding line 9 of zigzag on the sidewall of " L " type heating panel 6, prevent elastic clip 7 slippages.Horizontal expansion forms chute 10 and connecting plate 11 is installed respectively on the biside plate of half housing, connecting plate 11 cooperations of upper half-shell are inserted in the installation chute 10 of housing lower half, and connecting plate 11 cooperations of housing lower half are inserted in the installation chute 10 of upper half-shell.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection range of the present utility model.
