Title: Solar energy collector uses two-component heat transport medium - one in contra-flow to cover flow heat flow pattern reducing amount of heat surrendered back to atmosphere
Inventor: BECKER FRIEDRICH
IPC: F24S10/80
Filed: 1992-07-27
Abstract: A heat concentrating and heat pumping flat solar energy collector (2) constructed on a support (1). The novelty is that a fluid heat transporting medium consists of two components of which one evaporates at the operating temp. Further, that the heat transport medium seeps through a heat insulating element (3), in the opposite direction to the direction in which heat spreads towards the cover plate (2). Further that the heat transport medium increasingly absorbs heat from one or both components. Further the evaporated components and liquid residue dun along a light-absorbing area (4) to lower end of collector, such that the heat transport medium then passes through tubes (5) behind the light-absorbing area (4) so that heat is surrendered in contra flow to the light-absorbing area (4). Further that the tubes (5) or heat-exchanger vessels behind the light-absorbing surface (4) are kept very thin and prevent a return flow of the fluid. Pref., when the heat transporting medium is evaporated or condensed, use is made of the external energy of the heat transport medium so that when heat is surrendered at a lower temp. level than the max. collector temp., the heat which is extending towards the cover disc, is pumped back, and that additional heat can be taken up from the surroundings. ADVANTAGE - The appts. reduces the amount of heat energy surrendered back to the surrounding atmosphere.
