| 摘要 |
<p>The invention relates to a thermal generator (1) characterised in that it comprises at least one thermal module (10) including N adjacent magneto-caloric members (2) arranged in a circle about a central axis (A) and submitted to a magnetic field variation generated by a magnetic means (3) in order to vary their temperature. The magneto-caloric members (2) are associated with N pistons (40) driven according to a reciprocating translation movement by a control cam (70) in order to move the heat-carrier fluid contained in the thermal module (10) simultaneously in two opposite directions, so that a first fraction of the heat-carrier fluid flows towards a hot exchange chamber (5) through the magneto-caloric members (2) submitted to a heating cycle, and so that a second fraction of the heat-carrier fluid flows towards a cold exchange chamber (6) through the magneto-caloric members (2) submitted to a cooling cycle, and vice versa. The exchange chambers (5, 6) are coupled to outer calorie- an d frigorie-consuming circuits, such as heating circuits, air conditioning circuits, tempering circuits, etc.</p> |
