<p>A receiver (131 fig1) for light from a solar concentrator (133 fig1) and for outputting heated fluid comprising a solar absorber, a heat exchanger thermally coupled to the solar absorber 101 and arranged to heat a heat transfer fluid, an inlet duct 111 disposed along the length of the receiver for receiving heat transfer fluid, an outlet duct 110 disposed along the length of the receiver where the heat exchanger comprises a plurality of thermally conductive fins 106 (119 fig 5) extending across the width of the receiver between an outer edge and the centre line of the receiver, the outer edge of the fins are coupled to the inlet duct and inner edges at the centre line to the outlet duct such that the heat transfer fluid flows between the fins from the inlet to the outlet. The inlet duct preferably surrounds the outlet duct with the fins allowing fluid to pass between the two. The solar absorber is preferably curved and the fins are curved to be in contact with the solar absorber from the outer edge to the centre line. The solar absorber preferably includes a glass cover 104. The outlet duct may include a central divider 103 along the centre line of the receiver.</p> |
