Embodiment Construction

[0023]The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.

[0024]FIGS. 2-7 are various embodiments respectively showing a magnetocaloric module with reduced thermal dissipation and Galvanic corrosion issues, wherein the magnetocaloric module shown in FIGS. 2-7 may be capable to function as, for example, the active magnetic regenerative refrigeration (AMR) bed 10 of the magnetic refrigeration apparatus shown in FIG. 1.

[0025]In FIG. 2, an exemplary magnetocaloric module A is illustrated. comprising a bed 100. Also, a plurality of magnetic particles 102 and an insulating layer 104 formed in the bed 100. The bed 100 is formed with opposing two ends 150 and 160 such that a heat transfer fluid is allowed, for example water, to flow ...

Abstract

A magnetocaloric module for a magnetic refrigeration apparatus includes: a bed having an inner surface; a magnetocaloric material filled in the bed; and an insulating layer formed over the inner surface, isolating the magnetocaloric material from the bed. With the use of the insulating layer, thermal conduction between the magnetocaloric material and the bed can be reduced and Galvanic corrosion which may occur to the bed can be prevented. Also, a temperature gradient of the magnetocaloric module may be further extended.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to magnetic refrigeration techniques, and in particularly to a magnetocaloric module for a magnetic refrigeration apparatus.[0003]2. Description of the Related Art[0004]At present, almost all refrigeration technologies applied in an environment of room temperature, which is closely associated with the daily lives of humans, for example, a refrigerator, a freezing chamber, a room heating / cooling system, and the like, mostly employ a gas compression / expansion cycle. However, the refrigeration technologies based on the gas compression / expansion cycle have a serious problem of environmental destruction due to specific freon gas discharged into the environment. Further, as to an alternative freon gas, its adverse affects on the environment are also of concern.[0005]Thus, expectations have been raised for magnetic refrigeration technologies using a magnetocaloric effect as one of the environmenta...
