2. Description of the Related Art Conventionally, as a method of cooling an electronic component centering on an LSI mounted on an electronic device or a power device, for example, Japanese Patent Application Laid-Open
As described in Japanese Patent No. 21279, a method of dissipating heat from a heat generating member such as an LSI by combining a refrigerant bag and a heat pipe has been adopted.

FIG. 19 is a configuration diagram showing a conventional heat transfer device described in, for example, JP-A-6-21279.

In the figure, a protective metal container 1 has an opening 2 at its bottom.
Is provided. And the refrigerant bag 3 is stored in the lower part in the metal container 1 for protection. This refrigerant bag 3

I have. Then, when the refrigerant bag 3 is placed in the protective metal container 1, a part of the refrigerant bag 3 protrudes from the opening 2 to form a contact portion 5 that comes into contact with a cooled object 8 such as an LSI.

Further, the heat transfer tube 6 is housed in the protective metal container 1 so as to be wrapped in the refrigerant bag 3, and a radiation fin 7 is attached to one end protruding from the protective metal container 1 to the outside.

Embodiment 1. FIG. 1 is a schematic configuration diagram showing a water evaporative cooling device using an electrolytic reaction according to Embodiment 1 of the present invention.

In the figure, a solid electrolytic element 50 having a function of electrolyzing water molecules is arranged so as to divide a sealed can 51 as a sealed space into two spaces 51a and 51b as first and second sealed spaces. I have. Then, a DC voltage is applied to both surfaces of the solid electrolytic element 50 from the DC power supply 52. Water 53 is stored at the bottom of the space 51a. This water 53 is thermally connected to the cooled object 54. Condenser 55
Are provided in communication with the space 51b. This condenser 55
A radiator 56 that removes heat from the internal water vapor and dissipates heat to the outside is attached to the outer surface of the, and is configured so that the water vapor flowing from the space 51b is cooled, condensed, and accumulated at the bottom. Condensate reservoir and space at the bottom of condenser 55
The water storage portion 51a is communicated with the water passage 57. Further, the gas phase portion of the space 51b and the gas phase portion of the space 51a are connected by an air passage 58.

The spaces 51a and 51b are filled with oxygen gas and water vapor by reducing the pressure inside.

Here, the cooled object 54 is, for example, one on which an electronic component such as an LSI, which is a heating element, is mounted on an electronic substrate, and the surface thereof has an uneven surface according to the mounting state of the plurality of electronic components. . The cooling device is provided with such a cooled object 54.
This is applied when heat is removed from the electronic component, and the thermal connection surface 59 of the space 51a with the cooled object 54, in this case, the bottom of the sealed can 51, corresponds to the uneven surface of the cooled object 54. It is molded in advance on an uneven surface.

Therefore, the object to be cooled 54 is attached to the cooling device such that each electronic component is fitted into the recess at the bottom of the sealed can 51. Each electronic component is in close contact with the thermal connection surface 59 of the space 51a.

Next, the configuration of the solid electrolytic element 50 will be described with reference to FIG.

In the solid electrolytic element 50, an anode 41 and a cathode 42 are arranged via a catalyst 43 that promotes an electrolytic reaction so as to sandwich a solid polymer electrolyte 40 that selectively allows protons to pass therethrough. The anode 41 and the cathode 42 are fixed to both surfaces of the solid polymer electrolyte membrane 40 while holding the ends of the polymer electrolyte membrane 40, the anode 41, and the cathode 42.

As the solid polymer electrolyte membrane 40, for example, a proton exchange membrane such as Nafion-117 (registered trademark of Du Pont) is used.

As the anode 41 and the cathode 42, a porous electrode such as a platinum-plated titanium, tantalum or stainless steel mesh body, a metal plating body using fibers as a power feeder, or a carbon fiber nonwoven fabric is used.

 Next, the operation of the first embodiment will be described.

When a DC voltage is applied between the anode 41 and the cathode 42 from the DC power supply 52, an oxidation / reduction reaction represented by the following formula occurs on both electrode surfaces. At this time, as shown in FIG. 2, H ⁺ (proton) generated by the electrolysis of water at the anode 41 passes through the solid polymer electrolyte membrane 40 and is supplied to the cathode 42, where Offered.

Then, water is electrolyzed at the anode 41, and water is generated at the cathode 42. As a whole, water vapor on the anode 41 side is transferred to the cathode 42 side, and oxygen on the cathode 42 side is transferred to the anode 41 side.

^{_{Anode: H 2 O → 2H + +}} 1 / 2O 2 + 2e - _{^{cathode: 2H + + 1 / 2O 2}} + 2e - → H 2 O whole: H ₂ O (anode side) → H ₂ O (cathode side) O ₂ (Cathode side) → O ₂ (anode side) If the solid electrolytic element 50 is arranged so that the anode 41 is located on the space 51a side, the water vapor in the space 51a is moved to the space 51b side by this reaction, Oxygen in 51b is space
Moved to 51a side. As a result, the humidity decreases in the space 51a, the evaporation of the water 53 stored in the space 51a is accelerated, and a temperature drop is induced.

Water 53 stored in this space 51a is thermally connected
The heat generated inside the cooled object 54 is absorbed by the water 53 whose temperature has dropped in the space 51a. Thereby, the cooled object 54 is cooled, while the water 53 evaporates by endothermic. Then, the evaporated water vapor is pumped into the space 51b by the water vapor pumping action of the solid electrolytic element 50, the inside of the space 51a is always maintained at a low humidity, and the evaporation of the water 53 is accelerated.

The water vapor pumped from the space 51a to the space 51b is
It flows into the condenser 55 connected to the flow path 51b. The water vapor that has flowed into the condenser 55 is radiated to the outside by the radiator 56 to be cooled and becomes condensed water, which accumulates at the bottom of the condenser 55. And the condensed water collected at the bottom of the condenser 55 is
The water is sequentially returned to the bottom of the space 51a through the water passage 57. In this way, the water 53 in the space 51a is circulated without using a mechanical means such as a pump.

On the other hand, the oxygen gas in the space 51b is transferred into the space 51a by the oxygen molecule transfer function provided in conjunction with the water vapor pumping action of the solid electrolyte element 50. As a result, the pressure in the space 51a increases, the pressure in the space 51b is processed, and a pressure difference occurs between the two spaces. The oxygen gas in the space 51a is returned to the space 51b through the ventilation path 58 by the pressure difference. Therefore, the mutual transfer operation of the water vapor and the oxygen gas of the solid electrolytic element 50 is continuously maintained.

Next, the structure of the cooling device according to the present invention is
The principle that can be cooled will be described.

FIG. 3 shows the relationship between the dry-bulb temperature and the wet-bulb temperature with respect to the moisture content of the gas, that is, the relative humidity in a state where the water and the gas are in contact with each other. The dry-bulb temperature is the temperature of the gas in contact with the water, and the temperature of the water in contact with the gas falls so as to approach the wet-bulb temperature without limit.

For example, as indicated by a broken line in FIG. 3, the wet bulb temperature of a gas at a temperature of 30 ° C. and a relative humidity of 20% is the value of the point Q (16 ° C.). Therefore, the temperature of the water in contact therewith decreases to 16 ° C.

Therefore, if the water in contact with the low-humidity gas and the object to be cooled 54 are thermally connected, the temperature of the object to be cooled 54 can be cooled to the ambient temperature or lower.

As described above, according to the first embodiment, the two spaces 51a, 51 of the sealed can 51 in which the gas composed of oxygen and water vapor is sealed.
b, a solid electrolytic element 50 disposed so as to be divided into two parts, water 53 stored in a space 51a, a condenser 55 provided in communication with the space 51b, and a condensed water reservoir at the bottom of the condenser 55. And space 51
a water passage 57 that communicates with the water storage section of a, a ventilation path 58 that connects between the gas phase parts of the spaces 51a and 51b, and a DC power supply 52 that applies a DC voltage to both surfaces of the solid electrolytic element 50. Therefore, the water 53 and the gas are circulated without using mechanical means such as a pump, so that the apparatus is constituted by stationary equipment and the number of components is reduced. Thus, a miniaturization is possible, a micro-level or small-scale cooling such as a local cooling on the electronic substrate is possible, and a silent cooling device is obtained. Also, since there is no drive unit inside, a maintenance-free cooling device can be obtained.

In addition, since water is used as the refrigerant, there is no need to take environmental preservation measures as in a conventional apparatus using a refrigerant such as chlorofluorocarbon.

Further, since the gas sealed in the spaces 51a and 51b is composed of oxygen gas and water vapor, only the factors contributing to the electrolytic reaction are present in the spaces 51a and 51b, the reaction speed is increased, and the cooling capacity is increased. Can be increased.

In addition, since the bottom of the sealed can 51, that is, the thermal connection surface 59 is formed into an uneven surface in advance so as to closely adhere to the outer shape of the cooled object 54, the thermal connection surface 59 and the cooled object 54 Can be adhered to each other. Therefore, the heat of the cooled object 54 is quickly absorbed by the water via the thermal connection surface 59, and
54 can be cooled efficiently.

Embodiment 2 FIG. 4 is a schematic configuration diagram showing a water evaporative cooling device using an electrolytic reaction according to Embodiment 2 of the present invention.

In the figure, the sealed can 51 in the first embodiment is composed of two sealed cans 60, 61 connected by a ventilation member 62.
Then, the solid electrolytic element 50 separates the sealed can 60 into two spaces 60a, 60a.
It is arranged to be divided into b. A radiator 56 is attached to the outer surface of the sealed can 60 constituting the space 60b, and a condenser 55 is provided.
Is composed. Also, a space 61a formed by the sealed can 61
Is connected to the space 60a via the ventilation member 62. These spaces 60a and 61a are arranged vertically with the space 60a positioned above. Furthermore, the condensed water reservoir 63a at the bottom of the space 60b and the water storage 63b at the bottom of the space 61a are connected by a water passage 57, and the space between the spaces 60b and 61a has a water seal structure. Further, the gas phase portion of the space 60b and the gas phase portion of the space 61a are connected by a ventilation path 58. The spaces 60a and 61a form a first closed space, and the space 60b forms a second closed space.
The space 60a corresponds to a first space, and the space 61a corresponds to a second space. The spaces 60a, 60b, and 61a are filled with oxygen gas and water vapor by reducing the pressure inside.

The opposing wall surfaces forming the space 61a of the sealed can 61 are formed in advance into concave and convex surfaces corresponding to the concave and convex surfaces of the object to be cooled 54, and constitute cooling surfaces 64a and 64b. These cooling surfaces 64a and 64b are formed so that the concave portions are not arranged opposite to each other. And, on the inner wall surfaces of the cooling surfaces 64a and 64b, a porous plate having good thermal conductivity and water absorption,
The hydrated layers 65a and 65b are formed by fixing a net-like plate, a film-like plate, and the like. These water-containing layers 65a, 65b are immersed at their lower ends in the water 53 stored in the water storage section 63a, absorb the water 53 by the capillary action, and form a water film on the inner wall surfaces of the cooling surfaces 64a, 64b. ing. The water condensed in the condenser 55 and stored in the condensed water storage 63a is supplied to the water storage passage 63b.
And the wet state of the water-containing layers 65a and 65b is maintained.

In order to cool the object to be cooled 54 with the cooling device configured as described above, heat generating parts such as electronic components of the object to be cooled 54 are cooled by cooling surfaces 64a,
The object to be cooled 54 may be fitted to the recess of the cooling surface 64b and attached to the cooling surfaces 64a and 64b. Therefore, heat-generating parts such as electronic components
64a and 64b are in close contact with each other, and the heat generated by electronic components
Heat is absorbed by the water absorbed by the water-containing layers 65a and 65b via the layers 4a and 64b, and the object to be cooled 54 is cooled.

As described above, in the second embodiment, the water-containing layers 65a and 65b are disposed in the space formed on the anode 41 side of the solid electrolytic element 50. Therefore, as in the first embodiment, the apparent space
The water vapor in the spaces 60a and 61a is transferred to the space 60b, and the oxygen molecules in the space 60b are transferred to the spaces 60a and 61a, so that the spaces 60a and 61a are dehumidified and the space 60b is humidified. And the hydrous layer 65a, 6
The surface of the water absorbed in 5b comes into contact with the low humidity gas, and the temperature drops. Thus, the cooling surfaces 64a and 64b are cooled, and the object to be cooled 54 thermally connected thereto can be efficiently cooled.

Also, the condenser 55 is disposed above the space 61a, and the space 60a
And the space 61a are arranged vertically so that the space 60a is located above, the condensed water reservoir 63a is provided at the bottom of the condenser 55, the water storage 63b is provided at the bottom of the space 61a, and the condensed water reservoir 63a
And the water storage section 63b are connected by a water passage 57, and
The lower ends of a and 65b are immersed in the water 53 of the water storage section 63b. Therefore, since the specific weight of water vapor in the space 61a is smaller than that of oxygen, the difference in gravity causes the upper space 60a to pass through the ventilation member 62.
Go to a. The water vapor in the space 60b is condensed by the condenser 55 to become condensed water, which is dropped and collected in the condensed water reservoir 63a. Then, the water 53 stored in the condensed water storage section 63a is returned to the water storage section 63b through the water passage 57, and the water-containing layer 6
Water is absorbed by the capillaries 5a and 65b, and the water-containing layers 65a and 65b are maintained in a wet state. Further, the water absorbed by the water-containing layers 65a and 65b evaporates from the surface thereof into the space 61a, and the environment of water and steam is continued without requiring power.

On the other hand, the pressure in the spaces 60a and 61a increases due to the transfer of the oxygen gas from the space 60b. The oxygen gas has a larger specific weight than the water vapor, flows into the space 61a from the space 60a through the ventilation member 62, and descends to the bottom of the space 61a. And, no power is required, and the pressure
The oxygen gas is returned from the space 61a to the space 60b via.

Also, the oxygen gas flowing into the space 61a from the space 60a through the ventilation member 62 descends along the surface of the hydrated layers 65a and 65b, forming a low humidity environment on the surface of the hydrated layers 65a and 65b, Accelerates water evaporation.

Therefore, according to the second embodiment, the same effects as those of the first embodiment can be obtained.

In addition, since the cooling surfaces 64a and 64b are formed in advance on the concave and convex surfaces corresponding to the concave and convex surfaces of the cooled object 54, the cooling surfaces 64a and 64b are in close contact with the cooled object 54 and can be efficiently cooled.

Further, since the object to be cooled 54 can be cooled by each of the two cooling surfaces 64a and 64b, the whole system can be made compact.

Further, since the concave surfaces of the cooling surfaces 64a and 64b are formed so as not to face each other, the convex portion of the cooled object 54 attached to the cooling surface 64a is formed in the concave portion of the cooled object 54 attached to the cooling surface 64b. The pair of cooled bodies 54, 54 are located in a meshing state, and can be constructed as equipment having excellent earthquake resistance and shock resistance, and the whole system can be made more compact.

Third Embodiment In the second embodiment, the sealed can 60 is divided into two spaces 60a and 60b by the solid electrolytic element 50, the space 60b and the condenser 55 are integrated, and the cooling surfaces 64a and 64b are formed on the two front and back surfaces. Although the hermetic can 61 provided is communicated with the space 60a of the hermetic can 60 via the ventilation member 62, in the third embodiment, as shown in FIG. 5, cooling surfaces 64a and 64b are provided on two front and back surfaces. Two sealed cans with 6
1, 61 are communicated with the space 60a of the sealed can 60 via the ventilation member 62.

In this case, four cooling objects 54 can be simultaneously
Can be cooled, and the overall system can be made more compact.

When a DC voltage is applied from the DC power supply 52, an electrolytic reaction occurs at the anode 41 and the cathode 42, and steam is electrolyzed on the anode side to generate oxygen, and saturated oxygen is consumed on the cathode side to generate steam. That is, apparently, water vapor on the anode side moves to the cathode side, and oxygen on the cathode side moves to the anode side. Thereby, the space 71a side is dehumidified, and the space 71b side is humidified.

When the space 71a side is dehumidified, the inside of the space 72a communicating with the space 71a via the communication hole 73 is also dehumidified. Then, since the inside of the space 72a is kept at low humidity, evaporation of water from the surfaces of the water-containing layers 65a and 75b is accelerated, and a temperature drop of the water absorbed by the water-containing layers 65a and 65b is induced. Hydrous layer 65a, 65b
When the water absorbed in the space 72a evaporates, the water 53 stored in the bottom of the space 72a is absorbed by the water-containing layers 65a and 65b by the capillary action, and the water is supplied.

The object to be cooled 30 has wall surfaces 72 along the water-containing layers 65a and 65b.
b, 72c, the heat of the cooled body 30 is absorbed by the water absorbed in the water-containing layers 65a, 65b via the wall surfaces 72b, 72c, and the cooled body 30 is cooled. Will be

Water vapor evaporated from the surfaces of the water-containing layers 65a and 65b
It flows into the space 71a through 3 and contacts the radiator 74.

Here, when the outer peripheral temperature of the radiator 74 is equal to or lower than the upper limit temperature at which the cooled object 30 is cooled and held, the water vapor is cooled by the radiator 74 and condensed, and passes through the communication hole 73 due to gravity to be in the space 72a. And is absorbed by the water-containing layers 65a and 65b. In this case, the spaces 71a and 72a are arranged in the vertical direction, the radiator 74 is arranged in the upper space 71a, and the water-containing layers 65a and 65b are arranged in the lower space 72a to form a heat pipe. The heat is radiated from the cooled object 30 to the outside via the radiator 74 without being required.

When the outer peripheral temperature of the radiator 74 is equal to or higher than the upper limit temperature for cooling and maintaining the cooled object 30, for example, when the upper limit of the allowable temperature of the cooled object 30 is 40 ° C. and the outside air temperature is 50 ° C., Container 74
Does not condense the steam.

In this case, a current is supplied from the DC power supply 52 to the solid electrolytic element 70 to move water vapor on the anode side to the cathode side and oxygen on the cathode side to the anode side. Thereby, the water vapor in the space 71a is moved in the space 71b, and is maintained near the saturated water vapor state. The water vapor in the space 71b transfers the heat to the radiator 7.
The heat is released to the outside from 5 and condensed. This condensed water is space 7
The water accumulates at the bottom of the space 1b and is returned to the bottom of the space 74a sequentially through the water passage 57.

Oxygen gas generated by the electrolytic reaction of the solid electrolytic element 70 in the space 71a has a larger specific weight than steam,
It flows into the space 72a through the communication hole 73 by gravity.
At this time, the oxygen gas is heated by receiving Joule heat generated during the energization process of the solid electrolytic element 70, but the radiator 74 acts as a cooling device for the oxygen gas, is cooled, and flows into the space 72a. The oxygen gas flowing into the space 72a descends along the surfaces of the water-containing layers 65a and 65b, and is supplied to the space 71b through the ventilation path 58.

Also, due to the electrolytic reaction of the solid electrolytic element 70, hydrogen ions in the solid electrolytic element 70 move and react with oxygen on the cathode surface to generate water vapor. However, a small amount of hydrogen gas does not react with oxygen. Is released into the space 71b as hydrogen gas and accumulates at the top. This hydrogen gas is
It comes into contact with the noble metal catalyst layer 76 provided on the top of b and is converted into water.

Thus, according to the fourth embodiment, the basic configuration is the same as that of the second embodiment.
The same effect can be obtained.

In addition, since the solid electrolytic element 70 is formed in a corrugated shape, a large electrolytic reaction surface can be obtained in a small space, cooling efficiency can be improved, and downsizing can be achieved.

Spaces 71a and 72a are arranged in the vertical direction, and the upper space 7
A radiator 74 is placed in 1a, and the water-containing layer 6 is
Since 5a and 65b are arranged, when the peripheral temperature is low,
The power supply to the solid electrolytic element 70 is stopped to function as a heat pipe, so that the cooled object 30 can be cooled. Thus, power consumption can be reduced. And, when the outer peripheral temperature is high, the radiator 74 can act as a condenser to cool the oxygen gas flowing from the space 71a into the space 72a,
Cooling efficiency can be improved.

Here, although the description is omitted, the drive control means of the DC power supply 52 includes, for example, a sensor for detecting the outside air temperature, and a control device for controlling ON / OFF of the DC power supply 52 based on a detection signal of the sensor. can do.

Further, since the bottom of the spaces 71b and 72a is connected by the water passage 57 and the water 53 is stored at the bottom of the space 72a, the space between the spaces 71b and 72a has a water sealing structure, and the pressure difference between the spaces 71b and 72a is Is formed. Thus, oxygen gas having a large specific weight can be supplied to the positionally high space 71b without requiring power.

Further, the oxygen gas flowing into the space 72a from the space 71a through the communication hole 73 descends along the surface of the water-containing layers 65a and 65b,
Form a low humidity environment on their surface. Thereby, the evaporation of water from the surfaces of the water-containing layers 65a and 65b is accelerated.

Further, a noble metal catalyst layer 76 is provided on the top of the space 71b. The white metal element constituting the noble metal catalyst layer 76 has a catalytic action on hydrogen or hydrocarbons, and is decomposed at a low temperature by reacting them with an equivalent amount of oxygen. Since the inside of the space 71b is in an atmosphere of oxygen gas, if hydrogen gas is accumulated, it reacts with oxygen to cause a dangerous state.
The hydrogen gas released into b is converted into water in a very small amount by the noble metal catalyst layer 76 and consumed, thereby ensuring safety.

Further, since the noble metal catalyst layer 76 has a ventilation structure, hydrogen gas can be brought into countercurrent contact with the oxygen gas sent from the space 71a through the ventilation path 58 in the catalyst layer 76, and the hydrogen gas decomposition reaction Can be prevented to prevent stagnation of hydrogen gas, and safety can be further improved.

In the fourth embodiment, the noble metal catalyst layer 76 is simply provided at the top of the space 71b.
A noble metal catalyst layer 76 may be heated and held at an appropriate temperature. In this case, the decomposition reaction of the hydrogen gas is promoted, and the hydrogen gas can be rapidly consumed.

Fifth Embodiment In the fourth embodiment, the spaces 71a and 72a are vertically arranged linearly. In the fifth embodiment, as shown in FIG. 8, the sealed can 72 is held in a vertical direction. , Sealed can 71
Are arranged horizontally or obliquely, the periphery of the solid electrolytic element 70 is angled with respect to the cooling unit, and a water receiving pan 80 for receiving the condensed water condensed by the radiator 75 is arranged. In this case, the condensed water condensed by the radiator 75 is received by the water receiving pan 80, immediately flows to the bottom of the space 71b, and returns to the bottom of the space 72a through the water passage 57.

Embodiment 6 In this embodiment 6, as shown in FIG. 9, the closed can 61 in the second embodiment is provided instead of the closed can 72 in the fifth embodiment.

In this case, an effect combining the effects of the second and fifth embodiments can be obtained.

Here, the solid electrolytic element 100 is accommodated in the housing 101 such that the direction of the peak (wave trough) of the corrugated solid polymer electrolyte membrane coincides with the flow direction of the fluid.

In addition, the evaporator 102 is a heat-conductive and water-absorbing layer 106 composed of a porous plate, a mesh plate, and a film plate having water absorbency.
The lower end of the water-containing layer 106 formed on the inner wall surface of a is immersed in water 108 stored at the bottom of the sealed can 102a. Then, the sealed can 1 at the portion where the water-containing layer 106 is formed
02a is thermally connected to the object 30 to be cooled, and
It functions to absorb heat from zero and evaporate water from the water-containing layer 106. The evaporator 102 has an inlet 102b and an outlet 102c connected to an anode-side outlet 101d and an anode-side inlet 101c of the housing 101 via pipes 107a and 107b, respectively. A blower 104 is provided in the path of the pipe 107a, so that the gas filled in the anode-side space 101a of the housing 101 and the evaporator 102 can be forcibly circulated by the blower 104.

On the other hand, the condenser 103 is constituted by radiating fins 113 formed on the outer wall surface of the sealed can 103a, radiating the heat of the gas flowing inside to the outside through the radiating fins 113, and condensing and dropping the water vapor contained in the gas. It works to make it work. This condenser
103 has an inlet 103b and an outlet 103c connected to a cathode-side outlet 101f and a cathode-side inlet 101e of the housing 101, respectively.
They are connected via 107c and 107d. And blower 105
Is disposed in the path of the pipe 107d, and the cathode side space 1 of the housing 101
01b and the gas filled in the condenser 103 by the blower
105 makes it possible to force circulation.

Here, the anode side circulation path is the anode side space 101a, the pipe 107
a, the evaporator 102 and the pipe 107b, and the cathode side circulation path includes the cathode side space 101b, the pipe 107c, the condenser 103, and the pipe 107d.

The bottom of the evaporator 102 and the bottom of the condenser 103 are communicating pipes.
Linked at 109. Then, the intake sides of the blowers 104 and 105 are connected by an equalizing pipe 110. Furthermore, a platinum-based catalyst layer 1
Numeral 12 is provided in a part of the cathode-side circulation path, for example, in the path of the pipe 107c. This platinum-based catalyst layer 112 is made of fine powder of platinum, ruthenium, palladium, or ferrite,
It is formed of a metal oxide such as titanium oxide or the like formed into a granular material, a pellet, or a honeycomb-shaped material, and the metal is supported on the surface thereof.
Furthermore, a DC voltage can be applied to the solid electrolytic element 100 from a DC power supply 52.

In addition, oxygen or oxygen-enriched air is used as a gas flowing through the anode-side circulation path and the cathode-side circulation path, and an inert gas not involved in the electrolytic reaction is removed.

Next, the operation of the water evaporative cooling device according to the seventh embodiment will be described.

Low-humidity gas in the anode side space 101a is blown from the bottom of the anode side space 101a by the blower 104 to the anode side discharge port 101d and the pipe 10
It is sent into the evaporator 102 through 7a and the inlet 102b. The sent low humidity gas is forcibly raised along the water-containing layer 106 formed on the inner wall surface of the sealed can 102a, and becomes a forced airflow along the water-containing layer 106. Due to this forced airflow,
Evaporation of moisture is accelerated from the surface of the water-containing layer 106, and the gas becomes high in humidity, from the top of the evaporator 102 to the outlet 102c, the pipe 1
It is fed into the anode side space 101a through 07a and the anode side inflow port 101c. Then, the gas of high humidity flows downward along the anode-side electrolytic reaction surface of the solid electrolytic element 100, is returned to the intake side of the blower 104, and circulates in the anode-side circulation path.

At this time, in the process in which the high-humidity gas flows downward along the anode-side electrolytic reaction surface of the solid electrolytic element 100, water vapor in the gas is electrolyzed at the anode of the solid electrolytic element 100 to which a DC voltage is applied, and oxygen Converted to gas. Therefore, the gas flowing downward along the anode-side electrolytic reaction surface of the solid electrolytic element 100 is dehumidified to have a low humidity.

Further, when the forced airflow flows along the surface of the water-containing layer 106, the temperature of the water-containing layer 106 drops to the wet bulb temperature of the gas, and the wall surface of the sealed can 102a on which the water-containing layer 106 is formed is cooled.
Therefore, the cooled object 30 thermally connected to the sealed can 102a
Is cooled. At this time, since the water-containing layer 106 is immersed in the water 108 stored in the bottom of the sealed can 102a, the water-containing layer 1
When water evaporates from the surface of 06, water 108
Is absorbed by the water-containing layer 106, and the wet state of the water-containing layer 106 is maintained.

On the other hand, the gas in the cathode side space 101b is blown by the blower 105 from the top of the cathode side space 101b to the cathode side discharge port 101f and the pipe 107c.
And into the condenser 103 through the inlet 103b. The gas sent to the condenser 103 is discharged to the outlet 1
03c, the pipe 107d and the cathode-side inlet 101e are sent to the bottom of the cathode-side space 101b. Then, the cathode side space 10
The gas sent to the bottom of 1b flows upward along the cathode-side electrolytic reaction surface of the solid electrolytic element 100, and circulates in the cathode-side circulation path.

Here, in the process in which the gas flows upward along the cathode-side electrolysis reaction surface of the solid electrolytic element 100, oxygen in the gas is changed at the cathode of the solid electrolytic element 100 to which a DC voltage is applied.
Reacts with hydrogen ions that have passed through the solid polymer electrolyte membrane, and is converted into water vapor. Therefore, the solid electrolytic element 100
The gas flowing upward along the cathode-side electrolysis reaction surface is humidified to have a high humidity. At the same time, the gas is
The Joule heat generated by the current flowing through 100 is taken in, and becomes high temperature and high humidity.
At this time, a part of the hydrogen ions that have permeated the solid polymer electrolyte membrane are not bonded to oxygen but are mixed into the gas, and the hydrogen gas is contained in the platinum-based catalyst layer 112 disposed in the path of the pipe 107c. When passing through, it is decomposed and removed by the catalytic action. The high-temperature and high-humidity gas sent to the condenser 103 is cooled by being radiated to the outside through the radiation fins 113,
Water vapor is condensed and dropped on the bottom of the sealed can 103a. The condensed water collected at the bottom of the sealed can 103a is sequentially returned to the bottom of the evaporator 102 via the connecting pipe 109, and the amount of water 108 stored at the bottom of the evaporator 102 is secured. .

Oxygen generated on the anode-side electrolytic reaction surface is
It is returned to the suction side of the blower 105 via 110.

Generally, in the theory of electrolytic reaction and heat / mass transfer, the electrolysis reaction and heat / mass transfer can be performed at a speed several tens to several tens times higher in natural convection than in natural convection and several times higher in laminar flow. it can. According to the seventh embodiment, since the blowers 104 and 105 are provided in the anode-side circulation path and the cathode-side circulation path, respectively, the evaporator 102, the condenser 103, and the solid electrolytic element are provided.
The airflow flowing through both pole surfaces of the 100 can be made into a forced airflow by the action of the blowers 104 and 105. Therefore, the electrolytic reaction surface and the heat / mass transfer surface can be maintained in a turbulent or laminar flow region,
Electrolytic reaction and heat / mass transfer can be performed at high speed. As a result, the size of the solid electrolytic element 100, the evaporator 102, and the condenser 103 can be reduced, and the size of the device can be reduced.

In addition, since the solid electrolytic element 100 is formed by forming a solid polymer electrolyte membrane having a cathode and an anode on both sides in a corrugated shape, a large electrolytic reaction surface is obtained in a small space, and cooling efficiency is improved. And miniaturization can be achieved.

In addition, since oxygen is generated by consuming water vapor on the anode-side electrolytic reaction surface, the oxygen increases in the anode-side circulation path, and the pressure increases. According to the seventh embodiment, the blower
Since the suction sides of 104 and 105 are connected by the equalizing tube 110, oxygen generated on the anode-side electrolytic reaction surface is returned to the suction side of the blower 105 via the equalizing tube 110, that is, into the cathode-side space 101 b. Thus, an excessive increase in pressure in the anode space 101a is suppressed, and an oxygen-poor state in the cathode space 101b is avoided.

Further, since the platinum-based catalyst layer 112 is provided in the path of the pipe 107c, hydrogen ions in the cathode-side circulation path can be decomposed and removed by the platinum-based catalyst layer 112. Therefore,
It prevents hydrogen gas concentration from rising due to accumulation of hydrogen ions mixed into the gas without binding to oxygen, preventing accidents such as explosion when the concentration of hydrogen gas exceeds the safe allowable range. be able to.

In addition, oxygen or oxygen-enriched air is used as the gas flowing through the anode side circulation path and the cathode side circulation path to remove inert gas that does not participate in the electrolytic reaction. The element 100 can be downsized.

The gas flowing through the anode-side circulation path and the cathode-side circulation path is ideally composed of a gas that does not contribute to the electrolytic reaction, for example, a two-component gas of oxygen and water vapor that contributes to the electrolytic reaction excluding nitrogen gas and the like. is there. At this time, since the oxygen gas is a supporting gas, the environment becomes easily flammable. Therefore, it is necessary to sufficiently consider flammability and material selection. If flammability is a concern, or if it is desired to avoid being restricted by material selection, air or a gas whose oxygen concentration is enriched in an acceptable range may be circulated.

Further, in the seventh embodiment, excellent effects are obtained by arranging the fans 104 and 105 in the anode-side circulation path and the cathode-side circulation path, respectively, and forcibly circulating the gas in both circulation paths. However, a blower may be arranged in one of the anode-side circulation path and the cathode-side circulation path,
In this case, an effect is obtained by forcibly circulating the gas through one circulation path.

On the other hand, the cathode-side circulation path includes a first cathode-side circulation path including the cathode-side space 101b and the pipes 111e and 111f, and a second cathode-side circulation path including the condenser 103 and the pipes 111g and 111h.
And a cathode side circulation path. In addition, piping 11
The cross-sectional area of the pipe 1b and the pipe 111d is 4: 1, and the pipe 111f and the pipe 111
The pipe cross section with h is set to 4: 1. The other configuration is the same as that of the seventh embodiment.

Next, the characteristic operation of the water evaporative cooling device according to the eighth embodiment will be described.

The gas in the anode side space 101a and the gas in the evaporator 102 are sucked into the blower 104 through the pipes 111a and 111c, respectively.
It is mixed and sent out. Then, the gas sent from the blower 104 is divided into 4: 1 through the pipes 111b and 111d, and flows into the anode side space 101a and the evaporator 102, respectively. The gas flowing into the anode-side space 101a from the anode-side inflow port 101c flows along the anode-side electrolysis reaction surface of the solid electrolytic element 100, and converts water vapor into oxygen gas to dehumidify. After that, the dehumidified gas flows from the anode side discharge port 101d to the pipe 111a.
Is returned to the intake side of the blower 104. The gas flowing into the evaporator 102 from the inflow port 102b flows along the water-containing layer 106, and is humidified including water vapor evaporated from the surface of the water-containing layer 106. After that, the humidified gas is discharged to the outlet 10
From 2c, the air is returned to the intake side of the blower 104 through the pipe 111c, and the blower 104
The air is returned to the intake side of the tank and mixed with the dehumidified gas.

On the other hand, the gas in the cathode side space 101b and the gas in the condenser 103 are sucked into the blower 105 through the pipes 111e and 111g, mixed, and sent out. Then, the gas sent from the blower 105 is divided into 4: 1 through the pipes 111f and 111h, and flows into the cathode side space 101b and the condenser 103, respectively. At this time, the gas diverted to the pipe 111h side is
When passing through the platinum-based catalyst layer 112, hydrogen gas in the gas is removed by a catalytic action and flows into the condenser 103. The gas flowing into the cathode side space 101b from the cathode side inlet 101e flows along the cathode side electrolysis reaction surface of the solid electrolytic element 100, and oxygen contained therein reacts with hydrogen ions permeating the solid polymer electrolyte membrane. The solid electrolytic element 100 is converted into water vapor and humidified, and further heated by Joule heat of the solid electrolytic element 100.
Thereafter, the humidified and heated gas is returned from the cathode-side exhaust port 101f to the intake side of the blower 105 through the pipe 111e.
The gas flowing into the condenser 103 from the inlet 103b is:
The heat is radiated to the outside through the radiating fins 113 to be cooled, and the water vapor is condensed and dehumidified. Thereafter, the cooled and dehumidified gas is returned from the outlet 103c to the intake side of the blower 105 through the pipe 111g, and is returned from the cathode side outlet 101f to the pipe 1
It is mixed with the heated and humidified gas returned to the intake side of the blower 105 through 11e.

Condensed water condensed in the condenser 103 and collected at the bottom of the sealed can 103a is sequentially returned to the bottom of the evaporator 102 via the connecting pipe 109, and stored at the bottom of the evaporator 102. Water 108
Is secured. Oxygen generated on the anode-side electrolytic reaction surface is returned to the suction side of the blower 105 via the pressure equalizing tube 110.

As described above, according to the eighth embodiment, the blowers 104 and 105 are provided in the anode-side circulation path and the cathode-side circulation path, respectively, so that the gas is forcibly circulated. The electrolysis reaction surface and the heat / mass transfer surface can be maintained in a turbulent flow region or a laminar flow region, and the electrolysis reaction and the heat / mass transfer can be performed at high speed.

Further, the anode-side circulation path includes the anode-side space 101a and the piping.
A first anode-side circulation path composed of 111a and 111b;
And a second anode side circulation path composed of pipes 111c and 111d. Since the pipe cross-sectional areas of the pipes 111b and 111d are set to 4: 1, the flow rate of the gas flowing into the evaporator 102 from the blower 104 Is limited to about 20% of the total flow. So evaporator
The amount of heat brought into the water-containing layer is reduced, the rise in the temperature of the water-containing layer is suppressed, and the cooling efficiency of the cooled body 30 can be increased.

Further, the cathode-side circulation path includes the cathode-side space 101b and the piping.
A first cathode-side circulation path composed of 111e and 111f;
And the second cathode-side circulation path composed of pipes 111g and 111h, and the pipes 111f and 111h have a pipe cross-sectional area of 4: 1. Therefore, the flow rate of gas flowing into the condenser 103 from the blower 105 Is limited to about 20% of the total flow. Therefore, most of the gas circulating in the cathode-side circulation path circulates in the first cathode-side circulation path, and the gas is heated by Joule heat generated by current flowing through the solid electrolytic element 100, and water vapor generated by the electrolytic reaction is removed. Absorb and humidify. As a result, the gas that is diverted and flows into the condenser 103 becomes a gas humidified to near the saturation point at a high temperature equal to or higher than the external temperature without providing an external heating source. Therefore, even when the condenser 103 is air-cooled, the gas flowing into the condenser 103 is kept at an external temperature or higher, so that heat is radiated to the outside and cooled to a temperature below the dew point, condensing water vapor, Water vapor generated in the cathode side space 101b can be sequentially extracted in the form of condensed water.

Further, since the platinum-based catalyst layer 112 is provided in the path of the pipe 111h in which the gas flow rate is restricted, the flow rate load on the catalyst layer can be reduced, and the size of the platinum-based catalyst layer 112 can be reduced. .

In the eighth embodiment, the pipe cross section of the pipe 111b and the pipe 111d is set to 4: 1. However, the pipe cross section ratio is not limited to 4: 1. It is sufficient that a part of the total flow rate of the gas circulating through the evaporator 102 is diverted to the evaporator 102 side. Also, piping 1
Although the cross-sectional area of the pipe between 11f and the pipe 111h is set to 4: 1, the ratio of the cross-sectional area of the pipe is not limited to 4: 1.

In Embodiment 8, the gas flow ratio of both pipes is defined by the pipe cross-sectional area ratio of both pipes. However, for example, a throttle or a partition plate is provided on the exhaust side of the blower and the flow rate ratio of the gas to both pipes is provided. May be defined.

Ninth Embodiment In a ninth embodiment, as shown in FIG. 13, a heat exchanger 114 is provided in the second anode-side circulation path so that gases flowing through the pipes 111c and 111d exchange heat. .

The other configuration is the same as that of the eighth embodiment.

According to the ninth embodiment, the gas flowing through the pipe 111d is cooled by heat exchange with the gas cooled by the evaporator 102 flowing through the pipe 111c by the heat exchanger 114.

Then, the gas sent out from the blower 104 is split through the pipes 111b and 111d, and flows into the anode side space 101a and the gas-liquid contactor 120, respectively. The gas flowing into the anode-side space 101a from the anode-side inflow port 101c flows along the anode-side electrolysis reaction surface of the solid electrolytic element 100, and converts water vapor into oxygen gas to dehumidify.
After that, the dehumidified gas is piped from the anode side exhaust port 101d.
