Magnetic component compiling structure and magnetic refrigerator adapting magnetic component compiling structure thereof

Abstract

A magnetic component compiling structure and a magnetic refrigerator adapts the magnetic component compiling structure thereof. The magnetic component compiling structure has more refrigerating beds and less permanent magnet per volume. Hence, the magnetic refrigerator saves more costs during manufacturing, and achieves higher cooling efficiency.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61,245,455 , filed Sep. 24, 2009.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a magnetic component compiling structure and a magnetic refrigerator adapting the magnetic component compiling structure.[0004]2. Description of the Related Art[0005]Magneto-caloric effect, MCE, is a characteristic of a magnetic material. Hence changing magnetic flux of an outer magnetic field will change entropy of material itself and follow the processes of absorbing or exhausting heat. Therefore, so called magneto-caloric material, MCM, means a material which has remarkable MCE manner. Further, so called magnetic refrigerating technology means adapting MCM to replace traditional refrigerant, such as CFC, HCFC, HFC, etc., to achieve a more environment friendly refrigerator, thus amount of MCM used in a magnetic refrigerator is an important concer...

AI Technical Summary

Benefits of technology

[0012]In addition, the invention also discloses a magnetic refrigerator adopting a magnetic component compiling structure, the magnetic refrigerator comprises a magnetic component compiling structure, a driving mechanism, a controlling mechanism, and a heat exchanging mechanism. The magnetic component compiling is adapted to the multiple layers magnetic component compiling structure as mentioned before. The driving mechanism drives the central axis of the magnetic component compiling structure rotating, the controlling mechanism controls the driving mechanism, and the heat exchanging mechanism connects the first magnetic components and exchanges heat with MCM contained in the first magnetic components to achieving a cooling outcome.

[0013]It is necessary to perform some improvements in order to enhance working efficiency of magnetic refrigerator of the present invention. For example, a user in the art may change a shape of the first magnetic component so as to contain as most MCM as possible. For example, a user in the art may change a shape of the second magnetic component so as to generate a larger or more homogeneous magnetic field. For example, a user in the art may change a shape of a permanent magnet structure of the present invention, wherein the permanent magnet structure comprises a smaller surface area, a C-shaped magnetic structure, and an auxiliary soft iron so as to cast the magnetic field more concentrating and homogenizing to a refrigerating bed and enhance cooling efficiency.

[0014]As mentioned above, because the magnetic components are compiled along an axis direction, while disposing refrigerating beds on a plurality concentric circles with different radius, a larger amount of refrigerating beds per unit volume and a less amount of permanent magnets needed are both achieved. Meanwhile, the driving mechanism drives the magnetic component compiling sets respectively so as to let a user in the art choosing freely according to necessary, and the overall working efficiency will be enhanced too.

Problems solved by technology

The drawbacks of above-mentioned rotating magnetic refrigerator are utilization rate of volume is low and utilization rate of material is low, that is if a user thicken the refrigerating bed to increase overall amount of MCM contained, the magnetic field casted by the permanent magnets were weaken relatively.
