The specific embodiment
Fig. 1 is the front view of outward appearance of the refrigerator of the relevant embodiments of the present invention 1 of expression, and Fig. 2 is the sectional view of this refrigerator, and Fig. 3 is the refrigerant loop figure of the freeze cycle of this refrigerator.
In Fig. 1, Fig. 2, refrigerator main body 1 is made of the heat insulating box that is filled with heat-barrier material and has an opening.
On this refrigerator main body 1 from, switching chamber 4, refrigerating chamber 5 and vegetable compartment 6 that refrigerating chamber 2, ice-making compartment 3, variable temperature are set are set.Each chamber has the opening that makes each chamber and opens and closes refrigerator chamber door 7 (being opposite opened door 7A, 7B among the figure) freely, ice-making compartment door 8, switching chamber door 9, refrigerating chamber door 10, vegetable compartment door 11.
Rear lower portion at refrigerator main body 1 sets compressor 21.In addition, set cooler 22, above this cooler 22, set refrigerator internal fan 23 at the back side of refrigerating chamber 5.In addition, set white heater 12 in the bottom of cooler 22.
In Fig. 3, compressor 21, condenser 25, throttling arrangement 24, cooler 22 are connected by pipe arrangement, constitute the refrigerant loop of freeze cycle.By the effect of this freeze cycle, the cold air that is generated by cooler 22 circulates in refrigerator by refrigerator internal fan 23.
In the refrigerant loop of this freeze cycle, be condensed after device 25 condensations by compressor 21 compression and the cold-producing medium that becomes HTHP, become low-temperature low-pressure refrigerant at throttling arrangement 24, in the effect evaporation of cooler 22 by refrigerator internal fan 23, then, return compressor 21 once more.
For example, under the situation of evaporating temperature for-30 ℃ of pacts of cold-producing medium, the pipe arrangement of cooler 22 and the surface temperature of fin are below 0 ℃, because temperature is lower and below freezing than ambient air temperature, so airborne steam becomes frost and piles up around cooler 22, that is, frost.
To cooler 22 frost hinder the heat exchange of cold-producing medium and air.Increase as if the frost amount, then the resistance to heat of cooler 22 increases, the heat exchange performance reduction, and cooling effectiveness worsens.
Have again, if frost amount increase, then by the effect of refrigerator internal fan 23, the circulating resistance of flow air increases around cooler 22, air quantity reduces, refrigerator main body 1 can not be kept the cooling capacity of regulation, temperature rises in the refrigerator.
Because so, there is the problem of the quality maintenance aspect of food, so, the defrosting member is set on refrigerator 1.The white heater 12 that goes shown in Figure 2 is defrosting members.
This goes white heater 12 to be reduced to purpose to delay air quantity, is arranged on the heat insulating box 32, between cooler 22 and heat insulating box 32 recess 31 is set, and a certain amount of frost can be piled up.
If the refrigerator of 500 liters, then need until the 550cc degree frost amount, can both keep the volume of temperature in the refrigerator.
Figure 11 is the cooler and the peripheral stereogram thereof of the refrigerator of expression present embodiment 1.Under the surface-treated state that does not carry out cooler 22, in the spacing of fin that is arranged on the cooler 22 is under the situation of 5mm, block until the bottom of cooler 22, the volume sum of the sum of products recess 31 of the sectional area of cooler 22 and 5mm be the shortest obstruction white measuring.For example, be 40cm at the width (L) of cooler 22, depth (W) is under the situation of 7.5cm because about 400cc be cooler 22 keep the frost amount, so, need the volume of the recess 31 of 150cc.
The frost that is deposited in the surface of cooler 22 is the porous layer of ice and air.Below, use Fig. 4 and Fig. 5, the process that frost forms around cooler is described.
If air is cooled to below the dew point (saturation temperature) in cooling surface (cooler surface) cooling always, then near cooling surface, form mist, it is separated out as water droplet (condensing droplet) on cooling surface, attached to cooling surface.
If generate water droplet on cooling surface, then it becomes nuclear, and water droplet is grown up, and it is big that size becomes.At this moment, as shown in Figure 4, cooling surface is not being implemented under the special surface-treated situation, all sites of water droplet on cooling surface produces (with reference to (a) of Fig. 4) arbitrarily.
Therefore, have the position and the long position of the distance weak point between the water droplet.If water droplet is grown up, arrive the size of the degree of adjacent water droplet contact each other, then water droplet merges each other, becomes big water droplet (with reference to (b), (c) of Fig. 4).
But, in the water droplet on the cooling surface, because have the position and the long position of the distance weak point between the water droplet, so the water droplet at the position that distance is short merges easily, generates big water droplet.
Water droplet further is cooled at cooling surface and condenses, and becomes ice and drips, and drips the frost that generates needle-like from this ice, forms frost layer (with reference to (d) of Fig. 4) gradually.At this moment, under the identical situation of frost amount, the size of dripping (or the water droplet that is about to condense) as if ice is big, then becomes concavo-convex frost layer greatly, therefore, and the thickening of the maximum of frost thickness.
Because the flowing resistance of cooler 22 is determined by maximum frost thickness, so, the flowing resistance of the cooler that is made of the fin of non-processor increases, and reduces to the air quantity as the refrigerator internal fan 23 of cooler 22 air-supplies of cooler action, and cooling performance worsens easily.
On the other hand,, pore (little hole) is arranged on the surface of cooling surface, then become water droplet (back is set forth and described in detail) as karyomorphism easily if image pattern 5 is such.If pore is configured on the cooling surface equably, then water droplet generates (with reference to (a) of Fig. 5) with the distance of approximate equality, therefore, is difficult to cause the merging of water droplet, but generates little water droplet (with reference to (b), (c) of Fig. 5).
Water droplet further is cooled at cooling surface and condenses, and becomes ice and drips, and drips the frost that generates needle-like from this ice, forms frost layer (referring to (d) of Fig. 5) gradually.At this moment, under the identical situation of frost amount,, then become concavo-convex little frost layer if ice drips the slight greatly of (or the water droplet that is about to condense), therefore, the maximum attenuation of frost thickness.
Because the flowing resistance of cooler 22 is determined by maximum frost thickness, so, the flowing resistance that is had the cooler 22 that the fin 43 of a plurality of pores constitutes by the surface at cooling surface reduces, prevent reduction to the air output of the refrigerator internal fan 23 of cooler 22 air-supply of action, the cooling performance of cooler 22 is difficult to worsen, and compares energy-conservation with the situation of non-processor.
Like this, if use the fin 43 (cooling surface) of cooler 22 with a plurality of pores, then can form size, form is certain beautiful water droplet and also has ice to drip, it is concavo-convex little to constitute generation, the frost layer that maximum frost thickness is thin, the wind path pressure loss is little, and the reduction of cooling performance less and energy-conservation cooler 22.
Then,, then use Fig. 6～Fig. 8, illustrate as karyomorphism to become water droplet if pore (little hole) is arranged on the surface of the fin 43 (cooling surface) of cooler 22.
Air is lowered the temperature at cooling surface, becomes supersaturated air near cooling surface, becomes to be mixed with the vaporific of fine droplet in the air-flow.
The part of this mist is come advection by air-flow, is discharged from near the cooling surface, remaining on cooling surface as dew condensation.
At this moment, decide by the difference of the microstate at the position on cooling surface surface (trickle concavo-convex etc.) at the water droplet that where forms the initial stage (condensing droplet) of cooling surface, under the situation of the such non-processor of Fig. 6, do not know where the water droplet (condensing droplet) at initial stage forms.
Therefore, under the situation of non-processor, because that the position that water droplet forms does not have is specific, so water droplet produces at random, because the distance between water droplet is not certain, so, cause the merging of accompanying easily with the growth of water droplet, form big water droplet easily.
On the other hand, if as shown in Figure 7, at cooling surface pore is arranged, then the water droplet at initial stage (condensing droplet) forms in the position of the crest line of pore easily.Compare little or be not under the very big situation at the Oscillation Amplitude of the size of the size of pore and water droplet or steam, the crest line on the top of pore forms water droplet.
Therefore, if dispose a plurality of pores at certain intervals at cooling surface, then since the position of water droplet by specific be certain intervals, so, merge at water droplet, in the process of growth, generate little water droplet of uniform size in a large number.
In addition, as shown in Figure 8, compare under the very big situation with the size of water droplet or the Oscillation Amplitude of steam at pore, airborne moisture generates at the crest line on the top in hole and the inside in hole.Under this situation, also be if dispose a plurality of pores at certain intervals at cooling surface, then since the position of water droplet by specific be certain intervals, so, merge at water droplet, in the process of growth, generate little water droplet of uniform size in a large number.
But,, be necessary to generate little water droplet with respect to the water droplet on the cooling surface of non-processor, if the distance between pore is excessively left, the then also cooling surface condensation of the non-processor between pore forms water droplet, form big water droplet, therefore, must make the distance between pore to a certain degree little.In anodized described later, the distance between pore is about 20nm degree, and still, if distance between the pore below the 100nm degree, then with respect to the water droplet at initial stage, distance is not very big, and effect is the highest.
In addition, for the size of pore (length of diameter of equal value or minor face), also can be described as the same, if be 0.1mm (100 μ m) degree to the maximum, then may generate little water droplet, if but the size of the pore below the 100nm degree, with respect to the water droplet at initial stage, be not very big then, effect is the highest.
Fig. 9 is the stereogram of structure of cooler of the refrigerator of expression present embodiment 1.
Among Fig. 9, cooler 22 is a fin tube type, is made of fin 45 and heat-transfer pipe 46, and fin 45 has been carried out having the such processing of a plurality of pore 51a.
Though fin 45 is an aluminium, heat-transfer pipe is that the situation of copper is a lot,, be not limited thereto, so long as the good material of pyroconductivity, which type of material all can.For example, if make the heat exchanger that has used the aluminium identical with fin material as heat-transfer pipe, the two applies pore in fin surface and tube surface, and then energy-saving effect further increases.
In addition, the kind of cooler is not to be defined in this, for example, can use heat exchanger yet, and this heat exchanger uses flat heat-transfer pipe, does not possess fin, and heat transfer property is improved, and in this case, implements a plurality of pores at the outer surface of heat-transfer pipe and handles.Such cooler is made from aluminum mostly.
In addition, though from the intensity aspect of cooler 22, preferred pore 51a to be connecting the form setting of fin surface,, also can make the pore 51a that has connected fin, generates the not change of effect of little water droplet.
As at the cooling surface to cooler 22, that is, the surface of fin 45 applies the method for pore 51a, for example has based on anodised method.Figure 10 is the stereogram of the state that amplified of the surface of anodised fin that expression will have been implemented cooler.
Anodic oxidation can form pore simultaneously on the two sides of fin surface.
If with fin (aluminium) is anode, in acid solutions such as sulfuric acid, oxalic acid, phosphoric acid, chromic acid, under the alkaline solution moderate environments such as sodium phosphate, carry out dc electrolysis, then aluminium ion (the Al that dissolves from fin (aluminium)
3+) and water (H
2O) react, on aluminium, generate the diaphragm (anodic oxidation diaphragm) of aluminium oxide (alumina) as substrate metal.
In addition; because the formation speed of anodic oxidation diaphragm 50 and electric current or current potential and the anodizing time that thickness depends on two interpolars of being supplied with; so, when the pore 51a of the degree of depth that forms regulation, electric current or the current potential and the anodizing time of two interpolars that control is supplied with.
In addition, because the pore quantity (density) of each unit are and the current potential that pore diameter depends on two interpolars, so, for quantity and the pore diameter that forms regulation, control the current potential of two interpolars.
In addition, will form bossed mould (metal pattern etc.) with the interval of pore 51a to the aluminium surface pushing that becomes fin 45, in the depression of surperficial formation rule with matching.Then, if carry out anodic oxidation, be the center then with this sunk part, form pore 51a, can carry out the arrangement of pore 51a in an orderly manner, can aspect density, carry out high accuracy control.
Have again; for pore 51a and the airborne reaction of moisture that prevents to form because of anodic oxidation, and the situation of blocking, after forming pore, carry out warm braw heating fin 45 immediately with 100～200 ℃ of degree; remove the moisture that contains in the diaphragm, change into the operation of stable oxide.
Heat-transfer pipe 46 is inserted logical a plurality of through holes of the fin 45 of formation like this, form cooler 22 as heat exchanger.
In the diameter of pore 51a is trickle hole, for moisture freezes, need very big energy, Kong Yuexiao, the supercooling degree of moisture increases.That is, this is making frost delay, and can prolong defrost interval, and is energy-conservation.
Because the degree of depth of pore 51a is dark, the amount of moisture of water conservation is many in the hole, so, that frost delays effect, energy-saving effect further improves.If the degree of depth of pore 51a for example more than 10 μ m, then can access enough moisture-holding capacities, energy-saving effect is big.
In above-mentioned embodiment 1, be that the situation of aluminium is illustrated with the material of the fin 45 of cooler 22, but material is not limited to aluminium.For example, also the material of so-called valve metal (valve metal) as fin 45 can be used,, form pore 51a on the surface by anodic oxidation.
Valve metal is the general name that can form show the metals such as aluminium, tantalum, niobium, titanium, hafnium, zirconium, zinc, tungsten, bismuth, antimony of the protective oxide layer of electrolytic rectifier effect by anodizing.
Wherein, can for example be aluminium, titanium, zirconium, niobium, tantalum etc. as the fin 45 actual metals that use.Even use these metals, also can access the effect identical with aluminium.
Implement the fin 45 after the anodized and can be hydrophily, also can become water repellency.General situation is to become hydrophily (50 ° of contact angles of less than) after just handling, if the elapsed time then becomes water repellency (50 ° more than the contact angle).
But, because the size that the drop that forms on the surface of fin 45, ice drip is by size and the interval determination of pore 51a, so, no matter be hydrophily or water repellency, effect does not have any difference basically, can reach same effect.That is, along with time lapse, effect can change hardly, can continue energy-saving effect based on the method for anodized.
In addition, because pore 51a is necessary, so the sealing of hole of implementing in the general pellumina processing is handled, and becomes antipodal effect.
Performance when should improve frost by using, carried out surface-treated cooler 22 as described above, during obstruction the frost amount different.
For example, at the width (L) for cooler 22 is 40cm, depth (W) is 7.5cm, highly (T) is 20cm, spacing of fin is under the situation of cooler 22 of 5mm, the shortest cooler 22 of obstruction keep the frost amount carrying out under the above-mentioned surface-treated situation owing to be more than the twice of situation of non-processor, so, more than 800cc.
Therefore, the volume of the recess 31 of 50cc is just enough.Though 1% of the volume of the not enough cooler 22 of volume of recess 31 in this case,, if just enough more than 0.5%.
As mentioned above, the cooler 22 that uses as the evaporimeter of the freeze cycle of the refrigerator of present embodiment is provided with a plurality of pore 51a by the roughly whole face at fin 45 or heat-transfer pipe 46, be difficult to cause that airborne condensate moisture is on the surface, the water droplet that generates merges and becomes the situation of big water droplet, make the water droplet that causes when condensing little, form beautiful frost layer, reduce the wind path pressure loss, performance when improving frost, and, by reducing to be arranged on the recess 31 on cooler 22 and the heat insulating box 32, can be energy-conservation.
In addition, the means that pore 51a is set are not limited to anodized, and boehmite processing (ベ one マ イ ト processing) also can.In addition, obtain hydrophilic means and also can use the article that hydrophilic coating and water repellency coating are mixed.
