A ventilation fan can be used for exhausting air out from underneath roofs, and/or for being portable in use and application. The fan can include optimized airflow blades having a twisted configuration that can move at a rotational speed operation of up to approximately 500 rpm. The approximately 15 inch diameter twisted blades can be premolded on a hub that together form a single molded unit of plastic. They can also be fabricated using metal. The unit can be mounted in an exhaust outlet having a conical diffuser on or adjacent to a roof. Another embodiment allows for portable solar powered fans used anywhere there is a need for ventilation and moving of air. The blades can rotate by a solar powered motor, where the blades and motor can generate up to approximately 1040 cfm while using no more than approximately 16 Watts.

    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.

In contrast to known circuits, in which series-connected strings of solar cells are connected in parallel and have roughly identical no-load voltages, it is provided according to the invention that the strings of series-connected solar cells generate different no-load voltages to adapt to the current/voltage characteristic of the load. Preferably, at least one reverse-current blocking diode is connected in series with the string which generates a lower no-load voltage than the other.

  • Patent number: 5121818
    Abstract: A solar powered cooling apparatus for a vehicle brake system utilizing a solar cell panel mounted within a vehicle front bumper to selectively actuate a blower motor located within an air duct housing. The air duct housing is connected to the front bumper of which has a plurality of forward openings with filtering screens so as to direct cool air flowing from the openings to the associated disk brake rotor. A plurality of openings are also formed on the top panel of the bumper of which the solar panel is operatively associated and where the openings can be adjusted via a slide plate operative through a push-pull cable located in a passenger compartment of the vehicle.

  • Patent number: 5117744
    Abstract: A sensor for an air-conditioning system in a vehicle has a measuring head with a number of solar cells arranged in a defined pattern for determining the intensity of the solar radiation and the position of the sun relative to the sensor. Attachment elements on the sensor permit assembly of the sensor only in one way in the vehicle. A dome over the solar cells is transparent only to solar radiation.

  • Patent number: 5081912
    Abstract: A vehicle vent (12) for exhausting air from a vehicle occupant compartment includes a float valve (32) that prevents water that enters an outlet (24) of the vent from passing into the vehicle through the vent inlet (20) but which has a drain passage (36) for permitting a limited flow of the water to a drain (38) on the vent inlet side of the float valve (32). The vent (12) preferably includes a fan (40) that is most preferably energized by a solar panel (48). Mounting of the vent (12) can be provided on the vehicle roof, on the roof just forward of a vehicle back window, or as part of a sunroof.

  • Patent number: 5078047
    Abstract: There is provided in combination with a building roof over an air space requiring forced ventilation of solar energy heated air from the space through a vent hole in the roof, an electrically operated exhaust fan mounted in air exhausting relation on the roof and over the vent hole, and a solar panel for supplying electrical power to a fan driving motor when exposed to solar rays. Air exhaust passage through the device includes a backwash turbulence preventing ring-shape plate extending between a supporting ring body which is of smaller diameter than an exhaust air directing hood on which the solar panel is mounted, and a ring channel member supporting the exhaust fan in a manner to draw the exhaust air through the ring channel into the hood.

  • Patent number: 5072105
    Abstract: A solar radiation detecting device for an automobile air-conditioner includes a left solar radiation sensor, a right solar radiation sensor and a horizontal solar radiation sensor for detecting quantities of the sunlight coming into the passenger compartment of an automobile so that an incident direction, an incident altitude and an incident intensity of the sunlight are calculated based on the detecting solar radiation quantities. The incident direction and altitude are used to vary the distribution air discharged from a vent outlet of the air-conditioner into the passenger compartment.

  • Patent number: 5072106
    Abstract: A device for detecting the solar radiation quantity of the sunlight coming in the passenger compartment of an automobile is construct to correct a solar radiation quantity by adding an amount of correction to the solar radiation quantity obtained based on the composite of plural detected values from a solar radiation sensor when the direction of the sunlight is deviated from the direction of travel of the automobile beyond a prescribed range, whereby the solar radiation quantity used for the control of an automobile air-conditioner is prevented from being lowered in case of deviated solar radiation. The solar radiation quantity coming into a rear portion of the passenger compartment is detected and compared with the front solar radiation quantity. A larger one of the front and rear solar radiation quantities is used as a solar radiation quantity for the control of the automobile air-conditioner to cope with the solar radiation coming from every direction relative to the direction of travel of the automobile.
