Abstract

The invention provides a magnetic fluid refrigerating refrigerator, and belongs to household appliances; the refrigerator comprises a shell, a metal circulating pipeline section is arranged on the shell, a part of the circulating pipeline is arranged at the interior of the shell, the other part of the circulating pipeline is arranged on the exterior of the shell, and the external part of the shell is composed of an iron pipe; the internal part of the shell is composed of a copper pipe or an aluminum pipe, the circulating pipeline is filled with a magnetic fluid, and the circulating pipeline is connected with a circulating pump in series; and the circulating pipeline arranged on the exterior of the shell is tightly attached to a permanent magnet along the circulating pipeline. The refrigerator abandons a compressor refrigeration system of a traditional refrigerator and adopts a magnetic refrigeration system; compared with a refrigerating ring type magnetic refrigeration system, the refrigerator provided by the invention has the advantages of small volume, good magnetization effect, and good refrigerating efficient.

Description

The magnetic fluid refrigerator

Affiliated technical field

The present invention relates to a kind of domestic electric appliance, especially, is a kind of refrigerator, comprises refrigerator shell.

Background technology

Refrigerator is a kind of basic domestic electric appliance, is used for stored food, and its refrigeration system mainly comprises compressor, evaporimeter, condenser, choke valve and circulating line; Evaporimeter is located in the refrigeratory body, mainly is made up of copper pipe, and condenser is located at outside the refrigerator; Have fan, compressor compresses working medium makes its heat release of in condenser, liquefying, and liquid refrigerant is circulated to said choke valve and evaporimeter; Make it in evaporimeter, evaporate heat absorption, thereby reduce the temperature in the refrigerator.

For above-mentioned conventional refrigerator, owing to need compressor operating, therefore have bigger noise, in addition, the mechanical part that in the compression cycle system, relates to is more, damages easily.For this reason, processed the magnetic refrigerator according to the magnetic refrigeration effect at present, its principle is that paramagnet is when magnetization; Its inner magnetic order degree strengthens, that is its magnetic entropy reduces, and then paramagnet is with heat release; Extraneous entropy is increased, and when the paramagnet degaussing, its inner magnetic order degree reduce; Be that magnetic entropy increases, then paramagnet will absorb heat, and extraneous entropy is subtracted.In present magnetic refrigerator, main through an annulus that constitutes by paramagnet, inside and outside refrigerator, do not stop rotation and the acquisition refrigeration effect; For this kind refrigerating ring structure, need bigger arrangement space, this has just increased the volume of refrigerator; And because refrigerating ring needs rotation, so magnetizer can not be close to refrigerating ring; Air-gap between them will cause bigger magnetic leakage, and the magnetization that this is unfavorable for refrigerating ring influences refrigerating efficiency.

Summary of the invention

To the problems referred to above; The object of the present invention is to provide a kind of magnetic fluid refrigerator, this refrigerator has been abandoned the compressor refrigeration system of conventional refrigerator, adopts magnetic refrigerating system; And, has the advantage that volume is little, magnetization is effective, refrigerating efficiency is high with respect to refrigeration ring type magnetic refrigerating system.

The technical solution adopted for the present invention to solve the technical problems is: this magnetic fluid refrigerator comprises housing; Said housing is provided with one section metal circulating line, and this circulating line part is in said enclosure interior, and another part is in said outside; And the part in said outside is made up of iron pipe; Part in said enclosure interior is made up of copper pipe or aluminum pipe, is full of magnetic fluid in the said circulating line, and circulating pump of serial connection in the said circulating line; On the said circulating line of said outside, follow the endless tube road and be close to permanent magnet.

As preferably, said circulating line is serpentine shape in said enclosure interior and distributes, thereby improves its endotherm area, and can make in the housing evenly refrigeration.

As preferably, said permanent magnet is surrounded by the long permanent magnetism sheet of 2-3 sheet arcuation, leaves the space between each said permanent magnetism sheet, is beneficial to heat radiation.

Beneficial effect of the present invention is: this magnetic fluid refrigerator is when work, and by the circulation continuously in said circulating line of said circulating pump driven magnetic fluid, said magnetic fluid is magnetized in the refrigerator outside, and this moment, its magnetic entropy reduced; Emit heat, when it was circulated to refrigerator inside, magnetic was eliminated; This moment, its magnetic entropy increased, and absorbed heat, thereby in continuous cyclic process; Constantly the heat with refrigerator inside brings to the refrigerator outside, reaches refrigeration, and this refrigerator has been abandoned the compressor refrigeration system of conventional refrigerator; Adopt magnetic refrigerating system, and, have the advantage that volume is little, magnetization is effective, refrigerating efficiency is high with respect to refrigeration ring type magnetic refrigerating system.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

In Fig. 1, embodiment shown in Figure 2, this magnetic fluid refrigerator comprises housing 1, and said housing 1 is provided with one section metal circulating line 2; These circulating line 2 parts are in said housing 1 inside; Another part is in said housing 1 outside, and is made up of iron pipe in said housing 1 outside part, is made up of copper pipe or aluminum pipe in said housing 1 inner part; Be full of magnetic fluid in the said circulating line 2, and circulating pump 3 of serial connection in the said circulating line 2; On the said circulating line 2 of said housing 1 outside, follow endless tube road 2 and be close to permanent magnet 4.

All be arranged in the cavity 11 on this housing 1 surface at said housing 1 outside said circulating line 2, permanent magnet 4, thereby can make shell have comparatively smooth outer contacting face.

Above-mentioned magnetic fluid refrigerator, said circulating line 2 are serpentine shape and distribute in said housing 1 inside, thereby improve its endotherm area, and can make even refrigeration in the housing 1.

Above-mentioned magnetic fluid refrigerator, said permanent magnet 4 is surrounded by the long permanent magnetism sheet of 2-3 sheet arcuation as shown in Figure 4, leaves the space between each said permanent magnetism sheet, is beneficial to heat radiation.

Above-mentioned magnetic fluid refrigerator is when work, and by the circulation continuously in said circulating line 2 of said circulating pump 3 driven magnetic fluids, said magnetic fluid is magnetized in the refrigerator outside, and this moment, its magnetic entropy reduced; Emit heat, when it was circulated to refrigerator inside, magnetic was eliminated, and this moment, its magnetic entropy increased; Absorb heat, its circulation theory is as shown in Figure 3, thereby in continuous cyclic process; Constantly the heat with refrigerator inside brings to the refrigerator outside, reaches refrigeration, and this refrigerator has been abandoned the compressor refrigeration system of conventional refrigerator; Adopt magnetic refrigerating system, and, have the advantage that volume is little, magnetization is effective, refrigerating efficiency is high with respect to refrigeration ring type magnetic refrigerating system.
