Embodiment Construction

[0035] exist figure 1 In general, 10 marks the thermostat using the magnetocaloric effect. The temperature control device 10 comprises a temperature control body 12 of magnetocaloric material, which is designed in the form of a ring. The temperature control body 12 extending annularly around the axis of rotation A is enclosed by its radial inner side 14 , its radial outer side 16 and its two axial end sides 18 , 20 The temperature regulating body shell 22 surrounds. The temperature-control body 22 is thus accommodated in the substantially completely closed interior of the temperature-control body housing 22 .

[0036] The temperature-regulating body 12 made of a magnetocaloric material is porous or permeable, that is to say for example configured with flow channels, so that the temperature-controlling body can be circulated by a heat transfer medium (generally a liquid) for heat removal or heat supply or flow through.

[0037] The magnetic field arrangement generally desig...

Abstract

The invention relates to a thermostat, in particular to a vehicle thermostat, which comprises at least one, preferably ring-shaped, thermostat made of magneto-caloric material through which a heat-carrying medium can flow or / and circulate. , a magnetic field arrangement structure capable of rotating around a rotation axis, wherein the magnetic field arrangement structure provides magnetic field heating regions successively arranged around the rotation axis in a circumferential direction and cooling regions between each magnetic field heating region, wherein, using the adjustment The warm body provides a plurality of heat transfer medium flow areas arranged successively in the circumferential direction, wherein at least two heat transfer medium flow areas adjacent to each other in the circumferential direction are assigned to the heat transfer medium circulation sector, wherein at least one heat transfer medium The flow zone can be passed through or / and circulated by a heat input fluid in order to input heat into the heat transfer medium flow zone; or / and, at least one heat transfer medium flow zone can be passed through or / and circulated by a heat export fluid , used to conduct heat from the heat transfer medium flow area.

Description

technical field [0001] The invention relates to a thermostat, in particular a vehicle thermostat, which can be used for cooling or heating, for example, the interior of a vehicle using the magnetocaloric effect. Background technique [0002] In heat pumps that operate using the magnetocaloric effect, the magnetocaloric material is alternately moved into and out of the magnetic field. On movement into a magnetic field, a spin orientation of the electrons of the magnetocaloric material occurs under the influence of the magnetic field. This orientation of the spins or the orientation of the magnetic moment in the magnetic field leads to a decrease in the magnetic entropy. Because the total entropy of the system does not decrease, the entropy of heat, manifested as an increase in temperature, increases. The reverse process occurs if the magnetocaloric material moves out of the magnetic field. The temperature of the magnetocaloric material that moves out of the magnetic field ...
