The best form that carries out an invention

Invention described in the claim 1 of the present invention is to add volatility liquid in gas flow A The mist of body is done into saturation state, and becomes the gas that vaporific fine droplets M is suspended in large quantities Stream Aa passes into this gas flow Aa with a side's of the heat exchanger of a plurality of runners runner The fluid B that need cool off passes into the opposing party's runner, passes through a side's of heat exchanger at gas flow Aa During the runner, along with the temperature rise of making gas flow Aa the sensible heat of fluid B for gas flow Aa The saturation degree (relative humidity when volatile liquid is water) of its gas phase part reduces, and makes at gas The a large amount of fine droplets M gasifications that suspend among the stream Aa reduce gas flow Aa continuously by its heat of gasification Temperature, cooling fluid B person continuously whereby, the gas flow that fine droplets M suspends in large quantities The effect of Aa is that the interior Exchange of apparent heat with fluid B of runner that leans against heat exchanger is heated, by little Small droplet M gasifies and takes away heat of gasification, and the temperature of gas flow Aa reduces and cooling fluid B.

The 1st embodiment

The flat board 1 and wavelength 3.0mm made by aluminium or other sheet metals or polyester or other synthetic resin thin plates, the corrugated plating 2 of wave height 1.6mm alternatively and also the ripple direction of corrugated plating 2 orthogonal ground is overlapping and be in contact with one another step by step, obtain orthogonal crossflow heat exchanger as shown in Figure 2.In addition, on thin sheet surface, then produce hydrophily and increase surface area with the little convex-concave of formation such as shot-peening.In order to make the aluminium sheet possess hydrophilic property, use sheet material is immersed in the aqueous solution of sodium phosphate, clorox, chromic acid, phosphoric acid, oxalic acid, NaOH etc., perhaps short time impregnating method in boiling water generates hydroaropic substance on the surface of aluminium sheet.If so hydrophily is done on the surface of thin plate, at fluid B the occasion of air or other gases then, can prevent because the pressure that water droplet causes reduces the circulation deterioration that makes gas in the small through hole.

Though illustrate dull and stereotyped 1 and the combination of corrugated plating 2 for example as cross-current type heat exchanger 3, if form tiny ripple on the part of flat board, then surface area further increases, the heat exchanger effectiveness raising.In addition, if the surface of flat board 1 or corrugated plating 2 is done black, then photothermal radiation, absorption increase, the heat exchanger effectiveness raising.

As shown in Fig. 2, Fig. 3, a side's of orthogonal crossflow heat exchanger 3 small through hole group 4 configuration vertically substantially, the opposing party's small through hole group 5 configuration flatly substantially, as shown in Figure 3,

conduit

8a, 8b are installed on small through hole group 4 inflow entrance 4a and flow export 4b place respectively, pressure fan Fa and water spray device 6 are installed on conduit 8a,, pressure fan F are installed on conduit 9a inflow entrance 5a and the flow export 5b place that

conduit

9a, 9b are installed on small through hole group 5 (Fig. 2) respectively.Moreover Va is a valve of regulating the spray amount of water spray device 6 among the figure.

Preferably can thin as far as possible water droplet distributed equably as water spray device 6, for example air-atomizing nozzle etc. is suitable for.In addition, though the thin as far as possible aspect of water droplet is preferably about diameter 10 μ m, in the occasion of using air-atomizing nozzle to spray, as to make the maximum gauge of water droplet be about 280 μ m, then about 70% drop diameter can be given full play to effect of the present invention below 100 μ m.

Moreover air-atomizing nozzle is water and air-atomizing, if water and air also pressurizes, the water droplet of then spraying diminishes.Particularly, the size of spraying water droplet is subject to the influence of air pressure, preferably applies 3kgf/cm ²Above pressure.In addition also can be with the nozzle that only uses liquid.

Next the effect of this cooling device is described.As shown in Figure 3,, fine water droplet is sprayed among the air stream A in large quantities, leans on the heat of gasification of water droplet to reduce temperature, and improve relative humidity by in outside air or indoor air stream A, using above-mentioned water spray device 6.Then and then do to become to make the air stream Aa of the state that a large amount of fine water droplets M suspends, send into a plurality of runners inlet 4a of a side of heat exchanger 3 by the discharge pressure of pressure fan Fa.

If the air of high temperature stream B is sent into the inflow entrance 5a of heat exchanger 3 with the opposing party's pressure fan F, then air stream Aa seizes the sensible heat of high temperature air stream B during by the runner of heat exchanger 3 by the next door 1 (with reference to Fig. 2) of stream, and air flows the temperature rising of Aa.The relative humidity of air stream Aa reduces as a result, and a large amount of fine water droplets M gasifications that contained among the air stream Aa are by the humidity of its heat of gasification reduction air stream Aa, by next door 1 cooling down high-temperature air stream B.

The cooling principle of this cooling device is described in further detail.The steam pressure of liquid has the state of horizontal liquid level high than liquid under the drop state, and the more little then steam pressure of the diameter of this drop is high more.This phenomenon can be used as Kelvin equation and is expressed as follows.

10g(pr/p)＝20δM/ρrRT

In the formula, p is the steam pressure of horizontal liquid level, and Pr is the steam pressure of the drop of radius r, and M is a molal weight, and δ is a surface tension, and ρ is a fluid density, and R is a gas constant, and T is an absolute temperature.

Thereby the more little then gasification of the radius of water droplet is fast more, and cooling effect is strong more.And then in the process that gasifies in heat exchanger 3 of the water droplet M after spraying, the diameter of water droplet M diminishes, because along with the diameter of the water droplet M steam pressure that diminishes raises, so the gasification of water droplet M is carried out post in heat exchanger 3.In other words, fine water M gasifies in the short time at the utmost point in heat exchanger 3, seizes a large amount of heat of gasification.

If use above-mentioned formula to calculate, then in the occasion of 18 ℃ of water, when the water droplet radius is 1 μ, compares when steam pressure and liquid level are smooth state and raise 0.1%, when the water droplet radius was 10m μ, steam pressure raise 10% approximately.And then when the water droplet radius was 1m μ, steam pressure almost raise exponentially.If the air that fine water droplets M suspends to the water yield is like this sent into heat exchanger 3, then presents the phenomenon of water droplet M rapid ground vapourization in heat exchanger 3.

Use this cooling device to test.As shown in Figure 4, the air stream A that makes 25.9 ℃ of temperature, absolute humidity 8.05g/kg, relative humidity 39% is by water spray device 6, temperature is reduced to 17.5 ℃, do to become to make the air stream Aa of the relative humidity 100% that a large amount of fine water droplets M suspends simultaneously, this air stream Aa is sent into the almost small through hole group's 4 of configuration the inlet 4a vertically of heat exchanger 3 with wind speed 2m/ second.On the other hand, second the high temperature air B of 70.6 ℃ of temperature, absolute humidity 10.44g/kg, relative humidity 5.2% is sent into small through hole group's the inflow entrance 5a of the almost horizontal arrangement of heat exchanger 3 with wind speed 2m/ by pressure fan F.Even small through hole group 4 is not accurately vertical, water droplet also can be used under the state that suspends in the air and send.Fig. 5 is the air cooled air curve map of representing at this moment, and table 1 is its result of the test.Table 1 (sprayer is arranged)

Between high temperature air stream B and air stream Aa, carry out the sensible heat exchange, as mentioned above by flow the gasification of the fine water droplets that suspends among the Aa at air, reduce the temperature of air stream Aa continuously, cooling air stream B, air stream B does not improve absolute humidity and the temperature reduction, become the comfortable air of 18.6 ℃ of temperature, absolute humidity 10.44g/kg, relative humidity 78%, it is used as air feed SA.Gas stream Aa is owing to the air stream Ab that becomes 30.7 ℃ of temperature, relative humidity 100% by heat exchanger 3, and this air stream Ab is discharged in the atmosphere.

The sensible heat exchange efficiency η of this occasion ₁Be depicted as 97.9% as the formula in the table 1 (1), show that heat exchanger effectiveness is very high.B, SA, Aa represent air themperature separately in the formula (1).The spray amount of this occasion water droplet M is approximately per hour 8-15 liter.The air stream A of this occasion and the flow of B are about 180m ³/ hour.Heat exchanger is of a size of 0.25m * 0.25m=0.0625m ²Area since its

inlet

4a, 5a surface area be respectively 0.0625m ², percent opening is about 40%, so the sectional area of small through hole is 0.0625m ²* 40%=0.025m ², because wind speed is 2m/ second, so air quantity is 0.025m ²* 2m/ second=180m ³/ hour.

For contrast therewith, routine in contrast, orthogonal crossflow heat exchanger that will be identical with employee among the 1st embodiment does not use the result of the test of the occasion of water spray device to be shown in the air curve map of Fig. 6 and table 2 and Fig. 7 in tempering air stream.

Table 2 (not having sprayer)

B, Ba, A represent air themperature separately in the formula (2).The air stream A that temperature is 22.3 ℃ is owing to the air that the sensible heat exchange becomes 62.0 ℃ of temperature flows Ab, and the high temperature air stream B that temperature is 67.2 ℃ becomes the air stream Ba of 36.0 ℃ of temperature owing to the sensible heat exchange.Absolute humidity flows among A, the air stream B at air and does not all change.The sensible heat exchange efficiency η of this moment ₁Be depicted as 69.5% as the formula in the table 2 (2).At the occasion sensible heat exchange efficiency water spray is 97.9%, is 69.5% at the occasion sensible heat exchange efficiency water spray not, and by the spraying of water, heat exchanger effectiveness improves 30% approximately.Identical among other conditions of this occasion and the 1st embodiment the occasion of water spray.The 2nd embodiment.

Use this cooling device in addition equally, as shown in Figure 8, the air of 25.7 ℃ of temperature, absolute humidity 12.20g/kg, the relative humidity 59.0% bundle 2m/ air stream A of second that does to become a common practice, make it pass through water spray device 6, the air stream Aa that does into 20.2 ℃ of temperature, relative humidity 100% and vaporific fine water droplets is suspended in large quantities equably flows the inlet 4a that Aa sends into the small through hole group 4 of heat exchanger to this air.As the air of needs cooling the high temperature air of 34.2 ℃ of temperature, absolute humidity 14.41g/kg, relative humidity 43% is done into the wind speed 2m/ air stream B of second on the other hand, send into the small through hole group's 5 of heat exchanger inlet 5a.Carry out the sensible heat exchange between high temperature air stream B and the air stream Aa, air stream B becomes the cooling air SA of 20.6 ℃ of temperature, absolute humidity 14.41g/kg, relative humidity 95%.Gas stream Aa becomes almost 100% air stream Ab of 25 ℃ of temperature, relative humidity, and air stream Ab is discharged in the atmosphere.The air curve map of this moment is shown in Fig. 9, and result of the test is shown in table 3.

Table 3 (sprayer is arranged)

As shown in the figure, the heat of gasification of water droplet is passed to air stream B by the next door among the gas stream Aa, as shown in the air curve map, the absolute humidity of gas stream B is constant, temperature reduces arrival SA point (20.6 ℃) along the horizontal line of air curve map, air stream Aa is through the line of relative humidity 100%, and temperature is elevated to the Ab point.The sensible heat exchange efficiency of this occasion such as table 3 Chinese style (3) are depicted as 97.1%, with the sensible heat exchange efficiency of the 1st embodiment much at one.In other words, the occasion in that the temperature of fluid B descends if the temperature of air feed SA becomes 20.6 ℃, is fit to idle call, and then the spray amount of water can reduce.The spray amount of water is about 8 liters/hour.The 3rd embodiment

As shown in fig. 1, the tank D of the water droplet that increase acceptance and air stream Ab discharge simultaneously on the equipment of the Fig. 3 that illustrates in the 1st embodiment, the reflux that lodges in the water of this tank D is that pump P, aqueduct 10, motor-driven valve Va and water level control apparatus are water-level float Vs, level sensor Se, motor-driven valve Vb, and the spray amount adjusting device of water droplet sprayer unit 6 is thermocouple Ta, thermocouple Tb, electric signal amplifier C, motor-driven valve Va.Have among the figure with the part of Fig. 3 same numeral since be with in the 1st embodiment the identical person of part illustrated in fig. 3, so its explanation is omitted.

The aqueduct 10 that water in the tank D is refluxed to water spray device 6 is installed, and the way is provided with pump P and motor-driven valve Va therein.In addition, feed pipe 11 is installed on tank D, floating water-level float Vs on the water surface 13 in tank D, the power on/off magnet valve Vb that is located in the feed pipe 11 is connected with level sensor Se, as shown in the Q portion enlarged drawing of Fig. 1, with the variation of water-level float Vs and level sensor Se sensed water level, if the underwater drops to 13L, then magnetic valve Vb opens and make-up water, if the water surface rises to 13H, then magnetic valve Vb closes and stops the supply of water.

At the temperature sensor of the upstream of water spray device 6 configuration gas stream A thermocouple Ta for example, configuration temperature sensor thermocouple Tb for example in fluid B, C is connected between this thermocouple Ta and the Tb the electric signal amplifier.Detect the temperature difference of these two thermocouple Ta, Tb and send into the electric signal amplifier, along with temperature difference becomes big and operation motor-driven valve Va increases the water spray amount, along with temperature difference diminishes and the water spray amount is reduced.As required, when the water spray amount increases, the power of pressure fan Fa is increased, so that air stream Aa is quickened.

If this occasion is too much from the spray amount of water spray device 6, then fine water droplets accumulates on small through hole group 4 the internal face of heat exchanger 3 becomes current, can not fully gasify simultaneously, but drip.These current are compared with fine water droplets, and surface area becomes minimum, and when high temperature air stream B seizes heat, the gasification of water reduces, and is helpless to cooling.Thereby, the temperature of gas stream Aa is fully reduced, so can not reduce the temperature of high temperature air stream B fully.Become to make the fine water droplets M in the gas stream Aa to contain necessary amount equably if spray, cooling effectiveness height then, water also can be saved.The 4th embodiment

Also can use the mixing material of ethanol (78.3 ℃ of boiling points), methyl acetate (56.3 ℃ of boiling points), methyl alcohol volatile organic liquids such as (64.7 ℃ of boiling points) or volatile organic liquid and water, replace the water (100 ℃ of boiling points) that in sprayer 6, uses.

As shown in Figure 2, on two surfaces of the corrugate aluminium plates 2 of the next door 1 of making and wavelength 3.4mm, wave height 1.7mm with the aluminium sheet of thickness 25 μ, the microparticle of discrete bond hygroscopic agent silica gel, alternatively superimposed them, obtain the orthogonal crossflow heat exchanger 3 of the size of 250mm * 250mm * 250mm.Use this heat exchanger 3, the cooling device of assembling shown in Figure 10, the data when being used for the water of sprayer 6 with 45% aqueous solution replacement of methyl alcohol in the 1st, 2 embodiment are shown in Figure 10.This occasion is owing to replace water with methanol aqueous solution, so its boiling point reduces, temperature is that 25.9 ℃ air stream A (air stream Aa) after the methanol aqueous solution spraying is reduced to 14.6 ℃.

Because 14.6 ℃ of this air stream Aa flow 51.3 ℃ the heat exchange of B with high temperature air, obtain 17.2 ℃ Cryogenic air SA.If thereby use then can obtain Cryogenic air SA than only spraying with the more lower boiling liquid of water spray.The air curve map of Figure 11 is the air curve map of the state variation of the above air stream B → SA of expression and air stream A → Aa → Ab.The 5th embodiment

The equipment of present embodiment is to increase the device that a gas stream Ab that the outlet 4b from heat exchanger 3 is discharged refluxes to the gas stream Aa of high humility on the equipment that illustrates in the 1st embodiment as shown in Figure 12, at the upstream side of water spray device 6 humidifier is set.With conduit 8e the outlet 4b of heat exchanger 3 is connected with pressure fan Fc in Figure 12, with conduit 8d pressure fan Fc is connected with the runner of the gas stream Aa of high humility, connection is used for sending into as required the branched pipe K of outside air OA on the part of conduit 8e.

On humidifier 7,, can when the needs humidification, supply with water at the valve of the installation midway V of feed pipe Wp.As humidifier 7, there is the multilayer of using for example ultrasonic type, immersion to weave cotton cloth etc.

Make gas stream Aa by heat exchanger 3, with pressure fan Fc the exhaust Ab from outlet 4b is refluxed, Ac uses as gas stream.By humidifier 7 and then the gas stream Aa that becomes to make fine water droplets M to suspend in large quantities by sprayer 6 lanes, heat exchanger 3 is sent in circulation to this gas stream Ac as required.

In Figure 12, cooling end Co is set in the centre of conduit 8e, a plurality of fin Fe are installed on the periphery of conduit 8e, fan housing is installed on these fins and is connected pressure fan Fd, by coming cooling fins Fe by pressure fan Fd, fluid Ab in the cooling duct 8e, the moisture in the cooling high humility fluid Ab makes it dewfall, and dew is lodged in the water tank Da, often by the water in the valve Vc discharge water tank, be back to sprayer 6.

Though the example with the air cooling method that uses the orthogonal crossflow heat exchanger has illustrated fluid cooling means of the present invention, much less, can implement too in the gas beyond air or the cooling of water or other liquid.

The heat exchanger that uses also can use the above-mentioned orthogonal cross flow of heat exchanger replacement of the adverse current shown in reverse-flow, the Figure 14 shown in skewed crossing streaming, Figure 13 and cross-current combination.In the heat exchanger of adverse current shown in reverse-flow, the Figure 14 shown in Figure 13 and cross-current combination, all be that gas stream Aa, the fluid B that fine water droplets is suspended passes through in the small through hole along the direction of arrow among the figure respectively, discharge as gas stream Ab, fluid SA respectively, between two fluid Aa, B, carry out the sensible heat exchange.In addition, can use as shown in Figure 15, dull and stereotyped 1,1 ... between, clip a plurality of

Though in above embodiment, showed for example corrugated plating and dull and stereotyped mutual superimposed person as heat exchanger, but the invention is not restricted to these, so long as have a plurality of runners, the big person of water passage surface area is just passable, and the runner person who for example is provided with a plurality of heat-exchange fins at the two ends of heat pipe is just passable.The 9th embodiment

In Figure 19, the 18th, known refrigerator, inside has compressor (not shown).The 19th, heat exchanger, the runner 20 of one side is snakelike tubulose, the opposing party's runner 21 is for surrounding the shell-like of snakelike tubulose runner 20.

In a side's of heat exchanger 19 runner 20, the Freon gas of the high temperature that comes out from compressor (Chlorofluorocarbons hydrogen: the trade mark of U.S. DuPont company) or other refrigerant flow through, cooling water flows through in the opposing party's of heat exchanger 19 runner 21.

The opposing party's of heat exchanger 19 runner 21 22 is connected with a side's of orthogonal crossflow heat exchanger 3 runner by the road, is provided with circulating pump 23 in the way of pipeline 22.In other words, become the state that cooling water circulates between heat exchanger 19 and the cross-current type heat exchanger 3 under air-tight state.Moreover 9a, 9b are chambers.

Fa is a pressure fan, and the suction side is discharged side and combined with the upper end of chamber 24 atmosphere opening.In addition, the lower end of chamber 24 is connected with the opposing party's of orthogonal crossflow heat exchanger 3 runner inlet 4a.And the opposing party's of orthogonal crossflow heat exchanger 3 runner exit is to atmosphere opening.

Sprayer unit 6 is installed in chamber 24, the relative humidity of the air in the chamber 20 is being done in 100%, and then it is promptly vaporific to do into the state that a large amount of fine water droplets suspends.As sprayer unit 6, use air-atomizing nozzle, connecting the force (forcing) pump P and the compressor 25 of water.

D is a water receiving tank, is arranged on the below of orthogonal crossflow heat exchanger 3, and it is provided with adjutage 26.

As shown in Figure 20, one side's of this orthogonal crossflow heat exchanger 3 small through hole group's 4 axis is almost vertically arranged, another small through hole group 5 axis is almost flatly arranged, chamber 24 is installed on small through hole group 4 inflow entrance 4a, and pressure fan Fa and water spray device 6 are installed on chamber 24.In addition, on small through hole group 5 inflow entrance 5a and flow export 5b,

chamber

9a, 9b are installed respectively, on

chamber

9a, 9b, connect pipe 22.

The Action Specification of above formation is as follows.At first, be illustrated with regard to the cooling body that uses orthogonal crossflow heat exchanger 3.Make pressure fan Fa work and form air stream A, water sprayer 6 is done into gas stream Aa to water to wherein spraying.The water yield of spraying will surpass the amount that gasifies owing to spraying.So, the part gasification of the water droplet of being sprayed, owing to gasification seizes heat of gasification, the temperature of the gas stream Aa that is carried in the chamber 24 descends.In addition, the air in the chamber 24 are gas stream Aa, and relative humidity becomes 100%, and it is promptly vaporific to become the state that the particulate of water a large amount of in this air suspends.

Then, the air that suspends in large quantities of this fine water droplets enters a side's of orthogonal crossflow heat exchanger 3 small through hole group 4.When refrigerator 18 was running status, the temperature of the refrigerant of carrying in a side's of heat exchanger 19 runner 20 uprised, and carried out heat exchange with the water of carrying in the opposing party's of heat exchanger 19 runner 21.

The water of carrying in the opposing party's of heat exchanger 19 runner 21 by pump 23 circulations, enters the opposing party's of orthogonal crossflow heat exchanger 3 small through hole group 5 by pipe 22 and chamber 9a.Then, between a side small through hole group 4 and the opposing party's small through

hole group

5,1 carries out the sensible heat exchange through the next door.In other words, the cooling water of the small through hole group 5 by the opposing party cools off by the gas stream Aa of the small through hole group 4 by a side, and the gas stream Aa of the small through hole group 4 by a side is heated simultaneously.

So the relative humidity of the gas stream Aa of the small through hole group 4 by a side becomes below 100%, the particulate gasification of wherein contained a large amount of water, heat of gasification is seized and gas stream Aa is cooled.

Thus, the temperature of the gas stream Aa of small through hole group 4 by a side almost keeps constant low-temperature condition, so the cooling water of the small through hole group 5 by the opposing party is cooled in the gamut of the small through hole group 5a of heat exchanger 3 He on the total length continuously, it is constant that its temperature also almost keeps.

If this occasion is too much from the spray amount of water spraying device 6, then fine water droplet gathers on the next door of aggegation in the small through hole group 4 of orthogonal crossflow heat exchanger 3, become big water droplet or current, this big water droplet or current are compared with fine water droplets, surface area becomes minimum, the heat that seizes from refrigerant can not make the temperature of gas stream Aa fully reduce, thereby the temperature of refrigerant can not fully reduce.Become to make the fine water droplets in the gas stream Aa that evenly contains more more slightly than necessary Min. if spray, cooling effectiveness height then, water also can be saved.

Then, the water droplet of gasification does not accumulate among the water receiving tank D in the small through hole group 4 of orthogonal crossflow heat exchanger 3, is discharged by adjutage 26.As mentioned above, because the amount that the water yield of spraying from water spraying device 6 gasifies in the small through hole group 4 of orthogonal crossflow heat exchanger 3 no better than, so the water yield of accumulating among the water receiving tank D is seldom, even discarded also no problem fully.Thereby, do not recycle from the water of water spray device 6 spraying, do not have the thing that algae etc. is taken place.

Though in above embodiment, showed the example of water as the liquid that is cooled, but consider freezing of winter, also can in the water that is cooled, add the antifreezing agents such as ethylene glycol of 50% capacity degree, in order to prevent the corrosion of heat exchanger 19 or orthogonal crossflow heat exchanger 3, also can consider to add anticorrosive.The 10th embodiment

Another embodiment of the cooling device of refrigerator is shown in Figure 21.As follows with the difference of the embodiment of Figure 19.In other words, the 9th embodiment shown in Figure 19 makes water pass through the opposing party's of orthogonal crossflow heat exchanger 3 small through hole group, but this embodiment is the opposing party of orthogonal crossflow heat exchanger 3 is crossed in order from the circulation of air of pressure fan F small through hole group 5.

In other words, F is a pressure fan, combines with the inlet of chamber 9a.The outlet of chamber 9a is incorporated into the opposing party's of orthogonal crossflow heat exchanger 3 small through hole group 5 inlet.Small through hole group 5 outlet 5b goes up in conjunction with the inlet of chamber 9b, and the outlet of chamber 9b is incorporated into radiator 28.

In addition, pipeline 27 is set, so that order is passed through radiator 28 from the refrigerant that refrigerator 18 comes out.And the formation beyond the above-mentioned difference is identical with the 9th embodiment, so omit explanation.

This embodiment is cooled betwixt for air depends on the small through hole group 5 of pressure fan F by the opposing party of orthogonal crossflow heat exchanger 3, arrives radiator 28.Refrigerant from the high temperature of refrigerator 18 27 is sent radiator 28 to by the road, dissipates the heat of refrigerant.Air by small through hole group 5 is sent to this radiator 28.

In other words, radiator 28 leans on the small through hole group 5 chilled air streams by the opposing party of orthogonal crossflow heat exchanger 3 to cool off, and compares with the direct cooler of air of outer boundary, and efficient improves a lot.

In applicant's experiment, use orthogonal crossflow heat exchanger 3 identical persons with the 9th embodiment shown in above-mentioned Figure 19, when 35 ℃ of outside air temperatures, relative humidity 39%, make air in the small through hole group 4 of orthogonal crossflow heat exchanger 3, flow with pressure fan Fa with the speed of 2m/ second, with the water of 12 liters of/hour flows of sprayer 6 sprayings.So the temperature that enters the air of radiator 28 from orthogonal crossflow heat exchanger 3 becomes 18.6 ℃, the cooling effect of refrigerant is high.

This embodiment can be provided with the cooling device of refrigerator of the present invention before the radiator of existing air-conditioning equipment, can improve the efficient of the refrigerator of existing air-conditioning equipment or freezer etc. with simple construction.
