| 摘要 |
<p>It is disclosed a device for conversion of kinetic energy from an external source, e.g. wind or flowing water, into thermal energy, by means of internal friction in a liquid. The device comprises a pump (2) connected to a shaft (10) receiving kinetic energy from said external source. The pump (2) is provided for pumping the liquid in a circuit (4) comprising a unit (3) for converting the kinetic energy in the liquid into heat. The unit (3) is a throttle valve (3) which decelerates the liquid in the circuit (3) so that heat is generated. The circuit comprises two concentric tubes (32, 33), where a first tube (33) is located within a second tube (32), and heated liquid downstream of the throttle valve (3) is conducted in the inner tube (33), and return liquid upstream of the throttle valve is conducted in the outer tube (32).</p> |
