Abstract
This invention concerns a receiver unit () for a parabolic trough solar plant. The receiver unit () has a conduit () for conveying a heat transfer fluid () and a cover (), which is located about the conduit () such that a vacuum is formed between the conduit and the cover. The conduit () is designed to absorb thermal radiation. The cover () has a first portion () defining a window () through which incoming solar radiation () passes into the vacuum and onto the conduit () and a second portion () carrying a reflective surface () so as to reflect thermal radiation back onto the conduit (). The invention also concerns a method of reducing thermal radiation loss from a parabolic trough receiver.
