Heat exchanger using solar power - has outer transparent envelope and two inner ones of synthetic rubber and spiral pipe flow circuit

摘要

The heat exchanger has an internal space holding the primary heating fluid, surrounded by insulation. This is also covered by an envelope forming a heat exchange surface, formed largely by the circuit of the primary fluid. There is then an external covering, transparent, and in two parts. The envelopes are made of facets and those of the storage circuit and heat carrying circuit are made of synthetic material, such as synthetic rubber. The primary circuit is made of spirals of one or more pipes.
