Problems solved by technology

In addition, the exchange area between the air and the magnetocaloric element is very small, and also because the heat-carrying fluid is not a liquid but a gas, it cannot achieve a sufficient calorific value for industrial applications or civil use

Embodiment Construction

[0033] refer to Figure 1-8 ,in particular Figure 4 , the heat generator 1 of the present invention has a thermal module 10, and the module includes N adjacent magnetocaloric elements 2 that form a circle around the central axis A, forming an annular cylindrical structure. This embodiment is only an example, and the heat generator 1 may also have a linear structure.

[0034] The heat generator 1 has magnetic means 3 capable of subjecting the magneto-caloric elements 2 to changes in the magnetic field alternately, so that the temperature of the elements varies according to the Carnot cycle, and in each magneto-caloric element 2 alternately produces a heating cycle and a cooling cycle. The generator contains a heat-carrying fluid, which is driven by the circulation device 4 to move in the thermal module 10, so as to collect the heat and cold generated by the magneto-caloric elements during the successive heating and cooling cycles, and transfer the heat to The heat and cold ...

Abstract

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- and frigorie-consuming circuits, such as heating circuits, air conditioning circuits, tempering circuits, etc.

Description

technical field [0001] The invention relates to a heat generator having: a number of magnetocaloric elements; magnetic means for alternately subjecting said magnetocaloric elements to changes in a magnetic field and alternately producing heating and cooling cycles in each magnetocaloric element ; at least one heat transfer fluid, used to collect the heat and / or cold produced by the magnetocaloric element during the heating cycle and cooling cycle; at least one heat exchange chamber and cold exchange chamber, respectively located in the generator hot end and cold end; and circulation means for heat transfer fluid between said magnetocaloric element and said exchange chamber. The generator has at least one thermal module having at least one set of N magnetocaloric elements. Background technique [0002] Magnetic refrigeration technology has been known for more than two decades and the ecological and sustainable advantages it brings are known. Its limitations in effective the...
