A solar panel mounting structure 10 includes: a fixation member 12 as an angle member, which has an L-shape in cross section, and is firmly fixed onto a roofing 11 composed of a metal plate as a magnetic material; solar panels 14, each of which is rotatably held on the fixation member 12 while interposing an insertion/extraction hinge 13 mounted on an upper edge of an erected portion 12a of the fixation member 12; and a magnetic engaging device 15 provided between the solar panel 14 and the roofing 11 in order to detachably fix the solar panel 14 to the roofing 11. The fixation member 12 is firmly fixed to the roofing 11 while interposing a double-sided adhesive tape 16 and an adhesive agent 17 therebetween. The magnetic engaging device 15 includes: a cup-like casing 19 mounted to a lower surface of the solar panel 14 by a screw 18; and a ferrite magnet 20 firmly fixed into the casing 19.
Abstract:
A wind turbine with a tower; a nacelle supported by said tower; at least one unit to be cooled and arranged in the tower or the nacelle; a tower mounted heat exchange structure arranged outside the nacelle and tower; and a circuit facilitating a flow of a fluid medium between the at least one unit and the heat exchange structure. To improve thermal convection with the ambient space, the heat exchange structure comprises a set of panels mutually angled and extending outwards from the tower such that a flow of ambient air can pass transversely trough the panels and thereby cool the unit.
Abstract:
A device for coupling to a heat source, the device includes thermoelectric elements and a coupling magnet. The thermoelectric elements harvest heat to generate electric current. The coupling magnet provides a coupling force between the thermoelectric elements and the heat source. The coupling magnet regulates thermal flow between the thermoelectric elements and the heat source as a function of temperature of the coupling magnet. The device acts to protect the thermoelectric elements and other associated components from heat damage that might otherwise occur if the heat source generates too much heat.
Abstract:
A pre-chill system for reducing the temperature of air entering a cooling system includes a wicking material sheet and a series of frame segments. The frame segments are operable to secure the wicking material sheet to an outer casing of the cooling system in a path along which air enters the cooling system, each of the series of frame segments including one or more magnets magnetically attachable to the cooling system. A misting system is capable of directing moisture adjacent an outer face of the wicking material sheet. The frame segments are magnetically attachable to the outer casing of the cooling system over the wicking material sheet so as to retain the wicking material sheet against the outer casing with the wicking material sheet held between the frame segments and the outer casing.
Abstract:
An energy storage tank having a function of fixing energy storage units used for a working liquid includes a fixing assembly and a tank body that is for filling of the working liquid and has a bottom plate. The fixing assembly is received in the tank body and includes a fixing part to which the energy storage units are connected and an installation part that is fixed at the fixing part and disposed on the bottom plate. The installation part and the fixing part hold the energy storage units completely in the working liquid. Therefore, the energy storage units are fixed in the tank body in series or by group and distributed evenly in the working liquid such that each of the energy storage units can completely contact the working liquid to enhance energy storage efficiency of the energy storage tank.
Abstract:
The add-on heat sink includes an elongate base having a plurality of fins extending from a surface thereof. A magnetic layer is disposed on the bottom of the base, which permits the add-on heat sink to be installed on any ferromagnetic heated surface. The magnetic layer is composed of either a polymer matrix having a plurality of thermally conductive structural components and a plurality of magnetic particles dispersed therein, or a thermally conductive polymer having magnetic particles dispersed therein. Alternatively, if the heated surface is not ferromagnetic, the heat sink may be magnetically attached by adhesively attaching mating magnetic and ferromagnetic pads to the heat sink and to the heated surface. This configuration allows the add-on heat sink to be installed with minimal footprint. Optionally, a fan may be magnetically attached to the heat sink to cool the heated surface by both conduction and convection.
Abstract:
A heat sink assembly includes a heat sink and a grease cover. The heat sink includes a bottom plate. A layer of thermal grease is attached to a bottom surface of the bottom plate. A number of fasteners are mounted to the bottom plate. The grease cover defines a receiving recess for receiving the thermal grease. A number of magnets are fastened to the grease cover and attract the fasteners.
Abstract:
A heat exchange system can include a heat exchange unit and a magnetic element. The heat exchange unit can have a housing and a heat exchange surface configured to thermally couple to a subject of heat exchange. The housing can define an outer surface spaced apart from the heat exchange surface. A magnetic element, a ferrous element, or both, can be positioned within the housing. A coupling agent can have a complementary magnetic element, ferrous element, or both. The coupling agent can interact with the magnetic element, the ferrous element, or both, positioned within the housing. The coupling agent can be coupled to a substrate to retain the heat exchange unit relative to the substrate.
Abstract:
A heat exchanger is designed with variable heat transfer properties. The apparatus may include provisions for altering or varying the heat exchange characteristics of a heat exchanger by using one or more movable members that are connected to the inner surface of a heat exchange conduit to impede flow. The movable members may be positioned in a number of desired positions depending on the heat transfer rate needed.
