Solar energy concentrator/collector device

Abstract

The invention relates to a solar energy concentrator / collector device including a stationary reflector / concentrator (1) and reflector / concentrator modules (5) joined to a stationary structure (21) forming a matrix. Each reflector / concentrator module (5) includes a frame (6) and at least one reflective surface portion (8) configured to reflect the sun's rays and concentrate same in a line focus. The stationary structure (21) is formed by frames (6) attached to supporting sections (13a, 13b, 13c). A mobile receiver (2) includes a mobile structure (3) supporting receiving elements (35) parallel to the line foci. A tracking mechanism (4) is connected to a number of the supporting sections (13a) and to the mobile structure (3) in order to support and move the mobile structure (3) on the appropriate stationary reflector / concentrator (1) so that the receiving elements (35) follow a path comprising maximum confluence of the sun's rays reflected by the reflective surfaces as the relative position of the sun changes.

Description

technical field [0001] The present invention relates generally to solar concentrator-collector devices and more particularly to solar concentrator-collector devices that include stationary reflectors for reflecting and concentrating the sun's rays and reflectors that are moved by a tracking mechanism to follow the fixed reflectors as the relative position of the sun changes. A solar concentrator-collector device with a movable receiver at the maximum intersection of the sun's rays. Background technique [0002] Solar collectors configured to collect thermal or photovoltaic energy from the sun's rays directly impinging upon them are known. However, due to the low energy density of the impinging rays, such collectors are also energy-efficient. There are solar collectors of this type that use the thermal energy of the sun's rays to heat a heat transfer fluid. However, the heat transfer fluid is only capable of reaching low temperatures, which are not sufficient for converting...

Problems solved by technology

[0009] The disadvantage of the method used in said patent JP-A-10026423 is that it does not take into account other factors that may allow the use of smaller size receivers to optimize the performance of the device, such as the energy of the concentrated rays in the triangle. Reflected rays form triangles that are higher near the sides and lower near the vertices
