Abstract
The invention relates to an exciting refrigerating machine which uses a ferromagnetic refrigerating medium to cause temperature change under the action of a controllable exciting field to refrigerate. Rotatable barrel-shaped magnetic steel is manufactured by a controllable exciting device; the barrel-shaped magnetic steel is sleeved on a stator of a cylindrical heat exchange device made of high-temperature magnetic medium materials; and when the magnetic steel rotates by one cycle, magnetic medium assemblies A, B, C and D on the heat exchange device finish magnetization and demagnetization, i.e. heat is exchanged once. The magnetic steel rotates by 90 degrees, the magnetic medium assembly B on the stator of the heat exchange device is in a magnetizing state, and great magnetothermal effect is generated; thus, the magnetic medium assemblies are heated, and the circulating liquid in the stator of the heat exchange device takes out heat obtained by the temperature raise of the magnetic medium assemblies so that the magnetic medium assemblies are cooled; the magnetic medium assembly D on the stator of the heat exchange device is in a demagnetizing state, and the temperature of the magnetic medium assembly D can be reduced to be lower than the temperature of the magnetic medium assembly D before being magnetized; the circulating liquid in the stator of the heat exchange device is further cooled again by the magnetic medium assemblies; and the continuously cooled liquid is a refrigerating source, thus the aim of exciting refrigeration is achieved.
Description
Technical field
The present invention relates to magnetic refrigerating field-excitation refrigeration machine, is to utilize the ferromagnetism refrigeration working medium to cause the refrigeration machine of variations in temperature under the effect of controlled exciting field.
Background technology
What traditional refrigeration machine adopted is gas compression cycle system, and the freon gas body and function that just will liquefy easily is pumped into refrigerating device inner and absorbs heat, is sent to the refrigeration machine outside then.When gas during by behind coiled pipe of refrigeration machine, the pressure of compressor makes condensation of gas and distribute heat towards periphery.In the whole circulation process, consumed energy is wanted in the friction between freon and the tube wall.Therefore, even best gas compression-type refrigeration engine efficiency also can very big reduction.And the freon refrigerator is after discarding, and the freon that it discharges can enter atmosphere and damage the ozone layer, and is the public hazards of global warming.
In sum: traditional refrigeration system is system power consumption, poor efficiency, that pollute.
Summary of the invention
In order to solve problems such as traditional refrigeration system power consumption, poor efficiency, pollution, the invention provides a kind of excitation refrigeration machine, utilize the ferromagnetism refrigeration working medium to cause that under the effect of controlled exciting field variations in temperature freezes.
The technical solution adopted for the present invention to solve the technical problems is: utilize controlled excitation unit to make a rotatable barrel-shaped magnet steel, magnet steel divides four magnetic regions, and two exhausted magnetic regions of oxygen enrichment separate magnetism-filling area and demagnetization area; On the cylindrical heat-exchange device stator of making of high temperature magnetic working material, divide A, B, C, D magnetic working medium assembly with barrel-shaped magnetic steel sleeve on the circumference of heat-exchange device stator; When magnet steel rotated a circle, A, B, C, D magnetic working medium assembly had been finished and have been magnetized and demagnetize on the heat-exchange device stator, promptly-and heat exchange is once.Magnet steel revolves and turn 90 degrees, B magnetic working medium assembly is the state of magnetizing on the heat-exchange device stator, huge magnetothermal effect occurs, cause magnetic working medium assembly to heat up thus, the heat that circulation fluid obtains the rising of magnetic working medium assembly temperature in the heat-exchange device stator takes out and makes the cooling of magnetic working medium assembly; D magnetic working medium assembly is a demagnetized state on the heat-exchange device stator, temperature will drop to than temperature also low before magnetizing, magnet steel Rotate 180 degree, C magnetic working medium assembly is the state of magnetizing on the heat-exchange device stator, the huge magnetothermal effect of same appearance, cause magnetic working medium assembly to heat up thus, the heat that circulation fluid obtains the rising of magnetic working medium assembly temperature in the heat-exchange device stator takes out and makes the cooling of magnetic working medium assembly; A magnetic working medium assembly is a demagnetized state on the heat-exchange device stator, and temperature also can drop to than temperature also low before magnetizing, and circulation fluid is further cooled by magnetic working medium assembly once more in the heat-exchange device stator; The liquid that constantly is cooled becomes refrigeration source, reaches the purpose of excitation refrigeration.
The invention has the beneficial effects as follows: utilize the ferromagnetism refrigeration working medium to cause that under the effect of controlled exciting field variations in temperature freezes.It does not have compressor, without fluorine Lyons, and cycle efficieny height, low noise; atmosphere is not polluted, and safe and reliable during use, operation cost is not high; environmental protection and power savings advantages are fairly obvious, will replace traditional refrigeration modes in future, are the good equipment in the refrigerating field.
