摘要:
A low cost mass-produced solar module that extracts both electricity and heat from the sun. One or more reflectors held by a frame reflect the sun's heat into an absorber. Each reflector rotates about its axle to keep its reflected solar energy focused on the absorber. In one embodiment, solar heat is focused to heat fluid that flows to thermodynamic engines that convert the heat to electricity. Engine waste heat is also captured for use as building heat, home hot water or industrial process heat. In another embodiment, solar heat is focused onto photovoltaic devices that directly convert light into electricity. The fluid that cools the photovoltaic devices can be used for building heat, home hot water or industrial process heat. The frame shields the reflectors from ambient wind loads, supports reflector axles accurately and simplifies installation on roofs or walls of buildings. The frame, reflectors, absorber and ancillary components comprise a module that can be shipped, installed and operated by low skill. Most components are fabricated using “double wall” construction formed by two face sheets held apart by a core that reduces their weight and their cost. Reflector surfaces are curved to focus the sun and to provide additional strength. Module design includes methods to install, maintain and verify proper functioning of the modules. In addition, methods show how electrical energy can be derived from the module, both circulating fluids that power thermodynamic engines and by photovoltaic cells that are cooled by the circulating fluid. Sensors contained in the modules detect aberrant behavior and optimize reflector trajectories to extract the most solar heat available. Communication between modules allows optimization of an array of modules.

The present invention provides a reflector assembly for a solar collector, the reflector assembly comprising: a sheet-like reflector, and a bracket configured to (i) maintain the reflector in a predetermined curvature, and (ii) attach the reflector to a mount. The reflector may be used in the manufacture of light weight and low cost parabolic solar collectors of the type used to concentrate solar radiation on an absorber.

The present invention is directed to systems, devices and methods utilizing a proxy device that indicates directional aspects of redirected light from a corresponding light redirecting element by the position of one or more redirected light beams in one or more directions or coordinates on such a proxy device. The position characteristics of light redirected from the proxy device correlate to the aim of the light redirecting element associated with the proxy. This allows the proxy information to be used to accurately determine and control the aim of the light redirecting element.

The invention relates to a receiver system (104, 204) for a Fresnel solar plant (100), comprising an absorber tube (108, 208) defining a longitudinal direction, a mirror array (112, 212) that runs parallel to the longitudinal direction and is used for concentrating light beams onto the absorber tube (108, 208), and a support frame (114, 214) for the absorber tube and the mirror array. A first suspension (323) for holding the absorber tube and a second suspension (324) for holding the mirror array or at least parts of the mirror array are independently mounted on the support frame (114, 214). The first suspension (323) has first compensation means (758) while the second suspension (324) has second compensation means (758). The first and second compensation means (758) allow for different expansions of the absorber tube and the mirror array or at least parts of the mirror array in the longitudinal direction.

The invention provides a phase transformation heat exchange device. The device includes an inner tube, an outer tube, and a heat exchange medium; the space between the inner tube and the outer tube forms a whole or a part of a liquid phase region; a whole or a part of space inside the inner tube forms a vaporization region; the heat exchange medium with a relatively high pressure inside the liquid phase region enters the vaporization region with a relatively low pressure while being heated in vortex flow, and flows out of the device after being vapored, so as to complete heat exchange. The device can be applied to DSG systems of the solar energy photo-thermal field, and can also be applied to an input-output system of a heat storage system, or the field of boiler heating. It is achieved with safe operation, low cost, and good application range.

A receiver module for a solar power station receiver, including a metal structure and an absorber module, the metal structure defining a cavity extending along a longitudinal axis in a base of which the absorber module is housed. The cavity includes an aperture configured to be aligned towards at least one mirror of the solar power station, the aperture is edged by two side portions of the metal structure extending longitudinally on either side of the cavity. The receiver module also includes thermocouples positioned on each of the side portions relative to the longitudinal axis to detect a temperature difference between a reference temperature and two points of the metal structure that are opposite relative to the longitudinal axis.
