Solar Thermal Collector Insert

摘要

A solar thermal energy collector with integrated flowpath is provided. The insert can be connected to a solar collector manifold for collecting solar energy. The insert with integrated flowpaths can be surrounded by an evacuated chamber. A fluid can be used to transfer the heat collected from the insert. The insert includes first and second flowpaths for conveying the heat transfer fluid. The fluid flowpath is continuous and integral to the insert. The fluid flowpath may be comprised of a group of chambers designed for efficient transfer of thermal energy. Methods of manufacture of inserts with continuous flowpaths are provided. These may include methods for the extrusion of inserts with integral flowpaths from a single piece of material.
