<p>A liquid evaporator (1, 101) comprises an evaporation chamber (2, 102) with a liquid inlet (3, 103), a condensation chamber (4, 104) with a liquid outlet (5, 105), a heat conducting wall (6, 106) arranged with an evaporation surface (7, 107) in the evaporation chamber (2, 102) and a condensation surface (8, 108) in the condensation chamber (4, 104), a pump structure (9, 109) and a fluid connection passage (10, 110) between the evaporation chamber (2, 102) and the condensation chamber (4, 104), the evaporation chamber (2, 102) being adapted to contain a liquid (11, 111), whose surface (12, 112) delimits a gas pocket (13, 113), the connection passage (10, 110) ending in the gas pocket (13, 113). Thus, gas is pumped from the gas pocket (13, 113) through the connection passage (10, 110) to the condensation chamber (4, 104), the gas is condensed in the condensation chamber (4, 104) under emission of heat energy, a part of the heat energy is transferred through the heat conducting wall (6, 106) from the condensation chamber (4, 104) to the evaporation chamber (2, 102), and the condensate (26) is led away from the condensation chamber (4, 104) through the liquid outlet (5, 105). The advantage of the new liquid evaporator (1, 101) is that it can be made with a smaller number of components than state of the art liquid evaporators with vapour compression.</p> |
