Abstract
Apparatus is provided for removing the heat from within a generally sealed enclosure having a heat generating means disposed therein, such as a surgical light. The enclosure of the light includes a slightly domed top, a generally cylindrical side wall and a round bottom lens. The heat generating means consists of a plurality of lamps located within a cylindrical housing having a closed end which is located within the enclosure in the center of the top thereof. Radial fins extend about the circumference of the heat generating means, certain of the fins having arms extending radially therefrom. A large curved reflector having a series of lower slots forms an annular inner wall between the arms of the fins and the lens adjacent the outer circumference thereof. As such, the heat generated by the lamp housing is passed to the fins and travels to heat the upper ends thereof. This action causes the air adjacent the upper portion of the fins to be heated relative to the air present in the outboard reaches of the enclosure thereby causing airflow from the fins radially outward. The heat from the air is transmitted during such airflow to the top of the cover which then is radiated to the atmosphere. As the air loses its heat it drops to the lower portion of the annular wall and passes through the slots to be reheated by the fins as it passes therebetween to be reintroduced into proximity with the top of the enclosure.
