In housing, it is critical only that described housing is provided with hollow-out parts in the position of corresponding heater element, the outer wall of housing is fixed with metal
Heat sink；Circuit board is coated with heat conductive silica gel in the position of corresponding hollow-out parts, and one end of described heat conductive silica gel and heat sink connect
Touch, the other end is contacted with circuit board or heater element, thus the heat of heater element is conducted to heat sink.
In the course of the work, the heat that heater element is distributed can conduct to heat sink via heat conductive silica gel, due to dissipating
Hot plate is located at hull outside, therefore soon can dissipate heat, reduces the temperature of heater element and circuit board.Heat conductive silica gel
Also there is the effect of insulation, the short circuit risk of circuit board can be avoided.
Further, described heat sink is provided with, in the position of corresponding hollow-out parts, the protuberance protruding to housing direction, described convex
Portion passes through hollow-out parts, and the end face of protuberance is concordant with the medial wall of housing or is located in housing.Raised part can reduce as far as possible
The distance between heat sink and circuit board, so that the path when conducting along heat conductive silica gel for the heat is as far as possible short, thus reduce
The chance that heat is distributed in housing, thus improve the effect of radiating.
Further, it is provided with radiating gap between described heat sink and the outer wall of housing, between heat sink is provided with and radiates
The louvre that gap communicates.Extraneous air can walk the heat of heat sink by louvre discrepancy radiating gap from the two sides band of heat sink
Amount, improves radiating effect.
Specifically, described heat sink is provided with recess, and described recess is to direction protrusion, described recess and the shell away from housing
Described radiating gap is constituted between body.This recess not only defines radiating gap, also improves the intensity of heat sink.
Further, the outer wall of described housing is provided with interval and prominent supporting part, the end of described supporting part and radiating
The medial surface of plate offsets.Supporting part can be supported to heat sink, improve the bulk strength of radiator structure, and do not interfere with scattered
Thermal effect.
Heat radiation of electrical apparatus structure of the present utility model is by setting up metallic heat radiating plate and opening up hollow out in housing specific location
Portion, can directly derive the heat of heater element to the heat sink of hull outside, substantially improve radiating effect, and need not
The space of casing for electric appliances is increased, is very suitable for the radiating requiring stricter electrical equipment that takes up room.

Specific embodiment
Below against accompanying drawing, by the description to embodiment, for example involved to specific embodiment of the present utility model
The shape of each component, construction, the mutual alignment between each several part and annexation, the effect of each several part and operation principle etc. make
Further detailed description.
Embodiment 1:
Taking electric fan driver as a example (certainly, above-mentioned electrical equipment can also be that other has heater element to the electrical equipment of the present embodiment
Electrical equipment, and be not limited to electric fan driver), electric fan driver has housing 1 and the circuit board 2 being installed in housing 1, this electricity
One end of road plate 2 is provided with the larger heater element of caloric value 3.
Housing 1 is provided with hollow-out parts 4 in the position of corresponding heater element 3, and heater element 3 and hollow-out parts 4 may be contained within circuit
