Modular solar systems facilitating rapid assembly

摘要

A solar system for collecting solar energy, adapted to be rapidly assembled on site. The modular solar system includes a solar energy collector-assembly, having two wings of collectors, arranged in at least one row. The modular solar system further includes an energy-receiving-module, having a receiver unit, adapted to absorb the solar energy, a shaft, a support structure, a stand, disposed on rigid surface, a control-subsystem, a motor and a sun-following mechanism coupled to operate with the control-subsystem. The receiver unit has a diameter dr, wherein collected energy directed at the external surface of the receiver unit forms a pair of solar energy strips, each strip having a width de, such that de

1. A solar heating system for collecting solar energy, comprising:
a) a parabolic trough-type solar energy collector-assembly, comprising two wings (135) each having at least one parabolic collector, wherein each collector comprises:
i) a rigid body; andii) a mirror-grade polished metal sheet or mirror-grade surface operatively facing the sun; b) an energy-receiving-module (120), adapted to absorb the solar energy, comprising:
i) a receiver unit (122) having a body with a length (lr), a preconfigured diameter (dr), and an axis of rotation, wherein a series of working fluid flow passages allow selected working fluid to travel back and forth within said receiver unit, wherein said flow passages are arrayed around the axis of rotation and may be oriented in a circular geometry, proximal to the external surface of said receiver unit; andii) an elongated, substantially transparent, receiver-housing (124), having a generally triangular prism shape, wherein a first face of said receiver-housing faces away from said wings, and each of the second and third faces of said receiver-housing face respectively at least one parabolic collector, having substantially the same length as said receiver unit; c) a shaft; d) a support structure, including a stand to be disposed on a substantially rigid surface; e) a control-subsystem; f) a modulated flow temperature controlled pump; g) a rotating mechanism; and h) a sun-following mechanism coupled to operate with said control-subsystem,wherein said receiver (600) comprises an extruded body (610) having an external surface (612) and two open ends; wherein said two open ends are sealingly enclosed by a pair of fitted caps (620); wherein said extruded body is a pipe having an inner space (640) formed by an inner surface (642), and wherein said extruded body comprises a multiplicity of passageways (662, 664, 650) separated by internal walls (670, 672), disposed longitudinally between said two open ends; and wherein said passageways are interconnected to form a single elongated-passageway having one flow-inlet (650) and one flow-outlet being in flow communication with fitted openings formed in said caps;wherein said at least one parabolic collector collects the solar energy from the sun;wherein said collected energy is directed at the external surface of the receiver unit, as indicated by the sun-following mechanism; andwherein said collected energy that is directed at the external surface of said receiver unit forms a pair of solar energy strips along the external surface of said receiver unit, each strip having a width de, wherein de
