Abstract (en)

[origin: WO9417355A1] A problem in connection with fluid operated solar collector systems is in a simple and non-expensive way to be able to separate the circulatory system of the solar collector from a fluid based energy storage system without any considerable part of the supplied energy being lost. This problem is solved by a heat exchanger (2, 2a, 2b) according to the invention which is provided between the systems. This includes at least two concentric layers (12-15) of helically wound tubes (12a-15e) in a space that is surrounded by mainly cylindric surfaces (10-11). A method according to the invention for transfer of heat between a first fluid that circulates through a tube system (2, 2a, 2b) and a second fluid that surrounds the tube system consists in that the first fluid is pumped through the tube system containing capillary tubes so that the pressure drop across the tube system is at least 100 times larger than the pressure drop across the tube system in the second fluid which is self-circulating.
