Solar Roof-Ventilating Device

Abstract

A solar roof-ventilating device for compulsorily generating the flow of indoor and outdoor air includes a hollow ventilating casing provided on the roof to communicate the inside and outside of the roof with each other. The interior of the ventilating casing is provided with a heat dissipator constituted of a plurality of heat-dissipating pieces. A plurality of heat-conducting pipes penetrates through the heat dissipator. The other end of the heat-conducting pipe is connected to a heat-absorbing plate made of heat-absorbing materials. The front of the heat-absorbing plate is coated with a layer of black coating to facilitate the heat-absorbing speed of the heat-absorbing plate. Therefore, after the heat-absorbing plate has absorbed the solar energy, the heat can be conducted to the heat dissipator via the heat-conducting pipe. In this way, the temperature of the heat dissipator increases to generate a rising hot air, thereby to compulsorily cause the flow of the indoor air and achieve the ventilating effect.
