Parabolic Trough an overview ScienceDirect Topics

Parabolic trough systems, also known as linear concentrator systems, use U-shaped mirrors to focus most of the thermal energy they receive from the sun onto a receiver; called a heat absorber or a heat collector. The latter is in the form of a long pipe located at the center, specifically at the focal line of the parabolically curved reflectors.
