As magnetic Refrigeration Technique is in the continuous development in room temperature field, its application has obtained research and development energetically.
Mechanical energy is converted into heat under the action of a magnetic field by constantly experience plus magnetic and the demagnetization in running of cylindrical active magnetic regenerator device
Can, during motion, heat-transfer fluid flows through regenerator, with regenerator occur heat exchange, and be finally completed same Cooling and Heat Source exchange and reality
Existing kind of refrigeration cycle, the cold is brought in refrigerator casing, so as to reach the purpose for preserving food.
Refrigerator product on the market, mostly uses traditional refrigeration modes at present, and such refrigerator typically can
Compressor is wrapped using the plastics of engineering, to play dust control and noise absorption effect, but can be caused under the position of cold room of refrigerator
Drop so as to which, near compressor, this has resulted in when the compressor is operating, and refrigerator internal-external temperature difference is larger, to be remained low in case
Temperature must increase the running rate of compressor, and the power consumption that like this may result in refrigerator is increased.Also it is exactly refrigerator
Noise is also compare big, even can cause refrigerator failure when noise is excessive.The present invention passes through rational magnetic refrigerating system
Substitute traditional refrigeration modes so that product noise is substantially reduced, and overall structure is compacter, is greatly enlarged the application of product
Face, is particularly well-suited to the fresh-keeping of food.

Compact magnetic refrigerating cabinet.
To realize that the technical scheme adopted by the purpose of the present invention is：
A kind of magnetic refrigerating cabinet, by cylindrical active magnetic regenerator device, cylindrical permanent body, condenser, cold room, electromagnetic valve
First, electromagnetic valve two, electromagnetic valve three, electromagnetic valve four, centrifugal pump, small reservoir and heat exchanging fluid composition, the cylinder are living
Property regenerator cylindrical permanent body, the cylindrical active magnetic regenerator device and cylindrical permanent body phase are passed in and out by step motor drive
Adjacent one end connects four one end of electromagnetic valve and cold room one end respectively by pipeline, and the cylindrical active magnetic regenerator device other end is by pipe
Road connects one end of electromagnetic valve one and condenser one end respectively；The other end of electromagnetic valve four and electromagnetic valve one connects small-sized storage respectively
Liquid device entrance, the other end of cold room connect the outlet of centrifugal pump by electromagnetic valve three, and the other end of condenser passes through electromagnetic valve
The outlet of two connection centrifugal pumps, the entrance of the outlet connection centrifugal pump of small reservoir, places heat exchanging fluid in small reservoir.
The cylindrical active magnetic regenerator device constantly enters (go out) cylindrical permanent body by step motor drive, by electromagnetic valve
Control, the heat exchanging fluid respectively enters cylindrical active magnetic regenerator device, transfers heat to the condenser, cold is transmitted
To the cold room, so as to complete circulation, the purpose of chilled food is reached, the unnecessary heat exchanging fluid is stored in the small-sized storage
In liquid device.
The adiabator of the cylindrical active magnetic regenerator device is common aluminum silicate fibre product, glass wool product or asbestos.
The cylindrical permanent body adopts solid magnetic material.
The heat exchanging fluid is water.
Compared with prior art, the invention has the beneficial effects as follows：
1st, in the present invention, cylindrical permanent body uses solid magnetic material and does refrigeration working medium, it is to avoid conventional refrigerants
It is discharged in air, destroys high-altitude ozone layer and cause atmospheric pollution.
2nd, regenerator of the present invention is column type active magnetic regenerator device, and when heat exchanging fluid flows through, resistance reduces, and retention volume is little.
3rd, in the present invention, moving component is few, and without compressor etc., noise is substantially reduced.
4th, the present invention in refrigerant system configurations it is compact, it is taken up space reduction, increase refrigerator using space.
