Abstract

PURPOSE:To mitigate or remove an obstacle to the conduction of heat due to the accumulation of a gas in a fluid flow passage by a method wherein in view of the fact that the gas accumulates in the flow passage in the form of large and small two dimensional air bubbles, the flowing down and the separation of a liquid which hinders the upward flow and the separation of the gas as it makes itself a wall of bubbles is promoted by oscillating the liquid through an oscillating mechanism. CONSTITUTION:A photo-receiving surface 1 is formed of a thin metallic plate, an inorganic thin plate such as glass, a thin rubber or plastic plate or film processed to have a thick color such as black or to have a selective adsorbing surface and the thickness of the surface is in the order of 0.003-3mm., preferably in the order of 0.04-1mm.. Further, an electromagnetic oscillator 4 is fixed to the photo-receiving surface 1. As regards the oscillation frequency of the oscillator 4, it is simple and economical to use the commercial frequency as it is. The oscillation amplitude may be in the order of 0.01-2mm.. A cord 5 connecting the oscillator 4 to a frame 15 is adapted to fix the oscillator in situ in case when the oscillator is not fixed to the photo-receiving plate.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a falling thin layer type heat transfer device in which a liquid flows down in the form of a thin film on an inclined or vertical surface, and the liquid surface is covered with a thin plate-like body.
For example, the purpose is to improve the thermal efficiency and durability of equipment suitable for solar water heating equipment.

Conventionally, this type of heat transfer device includes a solar water heater that covers the liquid surface with a plastic film to prevent evaporation loss and light transmission loss due to condensation of water droplets on the heat-insulating cover surface, thereby increasing thermal efficiency. An example of this is US Patent No. 3146'7'7
No. 4 is mentioned, but since it uses a transparent plastic film, the reflection loss of sunlight is high, and since light enters the water flow path, it is easy for aquatic plants to grow, reducing efficiency. There was a problem. Japanese Patent Publication No. 54-8934
No. 25 has been improved by using a black or other dark-colored plastic film as a light-absorbing heat-receiving surface, but since both ends of the flow path are not sealed, the evaporation loss of water vapor is small, but there is a small amount of leakage. Therefore, the leaked water vapor condenses on the transparent heat insulating cover, causing a loss of light transmission. Furthermore, dissolved gas in the water accumulates as bubbles in the flow path due to heating, causing a problem between the heat receiving surface and the water flow. This may impede contact and reduce heat transfer efficiency. To prevent this, add jμ to □
It is said that it is appropriate to use a water-based heat medium.

However, in this case, it is necessary to add an even more expensive (3) heat exchanger to heat the water, and the benefits of making the solar heat collector simple and inexpensive are significantly reduced.

In either type, when directly heating water, the efficiency is not high due to problems such as bubble failure, and therefore it was considered that they could only be used for heating hot water pools.

The present invention relates to improvements to this type of heat transfer body, but the heat transfer surface (or heat receiving and dissipating surface) is not limited to plastic films, but can also be applied to thick thin plates.

As a result of research into heat transfer problems caused by air bubble accumulation in solar water heaters that have a φ heating surface that covers and is in contact with the liquid surface, a countermeasure was discovered and invented.

That is, when trying to reduce the liquid flow rate and raise the heating temperature in order to increase efficiency, the gas dissolved in the liquid becomes liberated due to the decrease in solubility ρ.

・：、・ If the cross section of the channel is large and the flow rate is small, the liquid will flow down to that point,
Bubbles can be separated and floated to the surface, but when the flow rate is small in a thin layer channel, the channel is narrow and it is difficult to replace the water and bubbles (4). It is also difficult to float upward and discharge.

For this reason, in the past, it was necessary to adopt a method in which the flow channel @ surface was made into a dog, and therefore the flow rate was also made into a dog, and the bubbles were forced downward. The disadvantage in this case is that the water circulation pump and water circulation piping are large and consumes a lot of electricity, which is not necessarily economical for small-scale applications, such as household use. On the other hand, it is not widely used for large-scale hot water pools because of its relatively low efficiency, resulting in large size, high pump head, and large power consumption. Focusing on the fact that gas exists in a state that can be considered as large and small secondary bubbles, we installed a vibration mechanism to apply vibration to the separation of liquid flowing down, which acts as a wall of bubbles and prevents the gas from rising and separating. This has succeeded in reducing or eliminating heat transfer obstacles caused by gases.

As a result, even if the liquid flow rate was reduced, heat transfer problems were less likely to occur, so the volumes of the circulation pump and piping were reduced, and power consumption was reduced.

In the case of the conventional forced circulation type, it is said to be about 60 kg/m H, and compared to this, it is about 10 = 15 kg/H, which is 4 to 6
can be reduced to ]. Compared to the conventional flow-down method, the improvement is even greater.

Moreover, it has the advantage of being able to be heated to high temperatures.

However, as a result of research, it has been found that by directly or indirectly applying heat to the liquid flow path, by fixing it to the main body of the device with a flexible structure in the direction of vibration, and by utilizing the vibration properties of the thin plate heat transfer material. It has now become clear that even with a small amount of power, it is possible to concentrate vibrational energy on the bubble and destroy the bubble wall.

It is even more effective when used in conjunction with other defoaming means, allowing high efficiency regardless of changing conditions. Power can also be reduced. Vibrations are generated electrically or mechanically.

A thin plate that electromagnetically generates vibration or impact and is in contact with the flow path;
Vibrate the insert, etc., or transmit the image of air or water using 1rf.
Examples include thin metal sheet composites forming flow channel walls, plastic sheets filled with glass, carbon powder, metal coating, metal oxide powder, etc., and supports such as support plates (back plates) for heat transfer bodies. .

Even if you apply localized imaging to liquid distributors, liquid outflow pipes, or objects inserted into the flow path, it may not be as effective. It is effective to make the vibration close to the point () into a linear or plane vibration. Applying vibration is also effective. (
(Of course, the latter can be used in the case of materials with high rigidity.)Next, vibration is applied to the flow path or the fluid (liquid such as water, gas such as air) that communicates with the flow path. The cell walls, etc. may be directly shaken (or rocked, displaced + the same) to promote liquid removal from the cell walls, etc. Examples of this means include electromagnetic vibration of a diaphragm, generation of sound, movement of a piston, and driving of a diaphragm.

The required power will vary depending on the equipment caused by vibration, measures to prevent leakage of the heat transfer body, etc., but it can be determined through experiments.

In order to achieve a high vibration effect with a small amount of power, it is preferable to use a timed switch to apply electricity intermittently and automatically to generate vibration electromagnetically. The vibration may be applied as sound or vibration of an air column or a liquid column.

In order to prevent the adverse effects of the parts that are still vibrating from reaching the heat insulation box and the liquid sealing part of the heat transfer body, the vibration generator is moved to the liquid sealing part of the heat receiving body,
It is preferable to avoid attaching to parts that are easily damaged, such as supporting parts and seams. Auxiliary vibration □, it is also preferable to avoid these in integral installation.

Support the heat transfer body, heat transfer body support plate, or support material using springs, cushioning materials, etc., or use cushioning materials to fasten them at important points, or use flexible structures to prevent vibrations from unnecessary or harmful parts. Preferably, transmission is prevented.

When applying vibration intermittently, the interval is 1 second to 2 hours, especially 1 minute to 30 minutes, and the duration of vibration is preferably about 0.1 second to 10 minutes per vibration. Electrically driven devices such as electromagnetic vibrations not only reduce power consumption due to intermittent operation, but also have the advantage of making parts smaller and lighter, reducing the need for cooling, etc., and improving durability. It was found that semiconductor circuits were sufficient for the switch and timer circuits, as they required less power.

Intermittent current may be used to drive a solenoid valve to manipulate a water flow (or pressurized air), and this may be used as motive power to generate vibrations.

In any case, vibration generation requires only a small amount of power, a small current, a low voltage, or a small amount of actuating material, and is characterized by high safety and low construction costs.

Additionally, equipment damage has become less common, and there is no longer any reason to avoid it.

The power source can be a battery or a small low-voltage transformer.

(9) It turns out that. When vibrations are applied continuously, only the supply of liquid is stopped intermittently. When vibration is applied intermittently, it is effective to stop the supply of liquid at least temporarily during the vibration.

This is because if liquid is supplied when the bubble walls are deliquid by vibration, a small amount of liquid is replenished to the bubble walls, which tends to cause the bubbles to break or to prolong the time it takes for the liquid remaining with gas to finish flowing down. This is because there is. There is an advantage that the vibration strong electric current can be reduced by stopping or reducing the liquid supply.

For thin-layer channels, unevenness of channel walls, surface treatment of channel walls (painting,
It is effective to apply vibration when processing is performed to promote foam breakage or drainage, such as welding of linings, wires, threads, thin plates, etc., erosion, knee sanding, corrosion, etc.). The effectiveness of these flow path treatments varies depending on the conditions of use and the properties of the liquid, but if vibration is added according to the present invention,
Comparatively (10) foam breakage and drainage are promoted even under adverse conditions, there are fewer obstructions due to bubbles, it is possible to use relatively inexpensive plastic film materials, such as those with low heat resistance, or it is possible to use a flow with a small slope. The bottom surface can be used more efficiently.

A thin metal plate, a thin plate of glass, etc., a thin plate of rubber, plastic, etc., a film, etc., with a thickness of 0.003 to 3 mm, particularly preferably Q
, 004~], mm.

Colorless, colored, milky white, transparent or semi-scented plastic or glass materials can also be used.

An electromagnetic vibrator as a vibrator 4 is attached to the surface of the light receiving surface 1. The power is 7W per m2.

The frequency is the same as the commercial frequency, or 1. It is simple and economical to use. The amplitude may be on the order of 0.01 to 2 mm, but it varies depending on the device structure and material.

If the vibrating end contacts the light-receiving surface in a point-contact manner, the wall of the thin plate (11) will be damaged, and in order to effectively transmit vibrations, a contact plate (which may be a rod-shaped object) 18 is provided. This size may be small if the light-receiving surface is made of a highly rigid stainless steel plate, but if it is made of a highly flexible material such as a plastic thin plate or film, a wide one as shown in the figure is effective.

The cable 5 connecting the vibrator 4 to the frame 15 may be fixed using magnetism. The latter fixing method, which does not involve adhesion, has the advantage of being simple and free of damage caused by adhesion or welding due to vibration.

The shape of the plate may be arbitrarily selected, such as frame-like or mesh-like, and it may be fixed by hanging from the frame 15 with cables, similar to the vibrator.

The timer 35 sets the operating interval and duration of operation of the vibrator, and may be of a variable type or a fixed type.

Frame 1 fixed: i1. ilx'tr,,,force,J:
1/"1 is..." Both devices are cheap, and those that operate at low voltage are cheap.
, it is advantageous throughout the country and can save on electrical work costs. Furthermore, it is particularly effective to make the solenoid valves 36 at the liquid inlets operable at the same time to stop the liquid flow when applying vibration (12). Vibration is applied continuously,
The liquid may be temporarily stopped intermittently.

1, the liquid (relatively low-grade water, suspension, salt solution, heat transfer cylinder) flows from the inlet 6 through the valve 36 and into the liquid distributor 7.
As a result, the stream iI@3 is distributed to the inlet of the flow path of the heat transfer body and receives heat from the light receiving surface forming the flow path wall while flowing down, reaches the outlet flow path while being heated, and is discharged from the outlet 9. Small bubbles generated in the channel flow down with the liquid flow, those that accumulate on the outlet side are discharged from the lower exhaust port 11, and large bubbles tend to accumulate in the channel and grow. The bubbles form in the same dimension and narrow the flow path, and the liquid flow in that area disappears, causing the heat transfer surface to overheat, increasing heat loss, and materials with low heat resistance (such as plastic films) It is easily deformed and becomes unusable. Therefore, when vibration is applied, the bubble walls are deliquified and disappear and flow down, and the gas rises smoothly, passes through the space near the liquid distribution benefit, and is discharged from the air exhaust port at the top, without causing heat transfer problems. In Figure 1, there is a vibrator etc. on the surface of the water heater, so it is preferable to use one with good heat resistance (J3), and a surface with low light absorption to prevent overheating is safe from the viewpoint of durability etc. .

Although it is simple to provide an electromagnetic vibrating body on the surface in this way, there are limitations because it is unavoidably supported by 4.
As the material of the heat transfer body is highly flexible, it can be used for both the upper and lower sides, and there are few restrictions. Depending on the operating conditions, suitable plastic films include polyethylene (highly heat resistant high density concubine is particularly suitable), polypropylene, polyester, and fluororesin. When using one film as a support plate, it is preferable that metals that are likely to generate rust be subjected to rust-proofing treatment, and that the structure maintains air permeability. If this happens, the vibrator will be more susceptible to damage and there will be a possibility of liquid leakage. In order to avoid such troubles caused by permeated water vapor, etc., Figure 12 does not allow air convection inside the heat insulating box, but shows the vicinity of a support that has a ventilation hole 38 that may form a ventilation path 37 or be covered with a porous material. FIG. 2 is a diagram showing an example of the structure.

391d rods, wires, and containers that may have a different cross section;
It is a protrusion or an addition of the support plate]6.

FIG. 2 shows a structure in which the support plate 16 is made of a thin plate and a support member 20 is placed near the nodes of vibration to facilitate vibration. A cushioning material 14 is used at the portion where the support plate is fastened to the frame 15 to reduce the vibrating force on the frame. Air vent] −〇,
Similarly, for the gas vent 11, liquid inlet/outlet, etc., use willow pipes, fittings, etc., fill the gap with the through hole of the frame etc. with cushioning material, or use a flexible material or structure such as a diaphragm. It is preferable to provide horizontal support. This also allows obstructions such as air bubbles to be effectively eliminated with less vibrational force.

FIG. 3 is a cross-sectional view of FIG. 1 with a transparent cutout 12 added thereto. It is preferable that the heat transfer body has a body structure in which the upper and lower sides are molded into a cylindrical shape or a bag shape, and there are no vibrating joints or joint flanges on the upper and lower surfaces of the heat transfer body. Further, a vibration suppressing member (such as a rod) may be placed on the vibration-suppressing portion of the heat transfer body where vibrations are not to be transmitted, such as an adhesive, weld, or liquid sealing portion on the side of the vibration 4J.

20 supports the lower thin plate 2 of the channel (in this case preferably a corrosion-resistant thin metal plate). Positioning at vibration nodes can attenuate vibrations and reduce damage. A heat insulating material such as aluminum foil or plastic foil (aluminum vapor deposited material may also be used) may be placed on the underside. 19
is a heat insulating material or space for heat insulation.

FIG. 6 shows an example in which the heat transfer body shown in FIG. 5 is added to the view from the back side. A vibrator 4 is installed on the top of the heat insulation box and transmits vibration to the liquid distributor 7 through a conductor 28. Of course, as in FIG. 5, it may be placed in a heat insulating box, and one of the beams 20 may be attached to the bottom plate 2 and vibrated.

FIG. 8 is an example of the longitudinal cross section of FIG. 7, and the support plate J6 is made of structural plywood or a heat insulating board that does not easily vibrate.

When using such a support plate that does not easily vibrate, if you want to drive parts other than the light-receiving thin plate 1, you must apply vibration parallel to the surface or place a space (such as member 47) on the support plate. or provide a buffer material (which may be Wr thermal material)
It is efficient to place a vibration in the flow path or directly apply vibration (reciprocating motion is also acceptable) to the channel fluid.

FIG. 9 shows a vibrator 4 attached to the exhaust port 11 to give air vibrations. Although the figure shows the diaphragm 34 being driven electromagnetically, it may be driven mechanically or by vibration transmitted through air piping. (In the latter case, the diaphragm is omitted, and in order to increase the efficiency of vibration, an orifice, a filter, etc. are used to provide air resistance, but the vibration is caused by an insert inserted parallel to the device 7 that communicates with the atmosphere, near the liquid distributor 7. FIG.

l ] Ri 1 The support member 20 is inserted onto the member 30 that vibrates only the insert 27 without connecting the insert 29, and the figure shows an example in which the thin support plate and the heat transfer body are easily vibrated. A type that uses elasticity to tighten is suitable because it is resistant to vibration. It is especially suitable for joining different materials. A product molded to have an irregular cross section can be used in place of a thick flange, and can be manufactured at low cost. Bolts and screw nuts 49 may also be used.

A ventilation passage 37 is formed in the.

Fig. 13 shows a communication pipe 40 in which the exhaust port 11 is communicated with the upper and lower parts.
A vibrator 4 is attached to the vibrator. Moreover, in this case, it is placed inside a heat insulating box (8), making the device convenient to handle.

In Fig. 14, the upper and lower exhaust ports]1 are connected to the front and rear of the diaphragm to increase the vibration efficiency. Figure 15 shows a cross section of Figure 13.

In Fig. 16, these are housed in the lower part of the storage box, and when placed on the surface, they are not exposed to 1.1 temperature of light, so they are highly durable. The location near the bottom of the insulation box is convenient for handling during operation. Needless to say, Sai Sen also installed a small pig for handling in the handle section. Although an example is shown in which a septum 41 is inserted in the middle of the pipe to prevent moisture damage, this may be omitted.

Figure 18.19.20.2.1 is a diagram showing the formation of thick 443 liquids when used together. Creating a relatively narrow gap, a lyophilic area (or, conversely, a lyophobic area) to destabilize the cell walls will promote the flow of liquid. Surface #11 work 44 is painting, baking, and sanding. Various auxiliary channels may be combined.

It can also be used.

When the distance is long, a relatively rigid tube is appropriate. A device with a diameter of about 1 to 30 mm can send vibrations of about 2 to 30 Qm, and since no electrical wiring is required, construction costs can be reduced and it is safe.

Example 1] With the device configuration shown in Figure 2.3, the vibrator is an electromagnetic vibration generator.
@6 (12W, 50Hz power supply, output frequency 25
~100 Hz variable) was placed in the center of the heat receiving surface (painted black). The heat receiving surface 1 is made of stress corrosion resistant stainless steel (SUS 444) with a thickness of 0.3 mm, and the flow path lower surface 2i
j:I is a vinyl fluoride polymer film with a thickness of 0.03 mm. The edge matching of both was performed as shown in Fig. 1.

Since both sides are flexible and movably overlapped, there is little vibration fatigue.Since the edges are raised, there was no γ7 tremor of liquid or steam even with weak tightening. There is no perfusion in response to current fluctuations, and the flow rate is 10 to 1 o per 1 m of width.
There was no problem even with a large flow rate change of 0 kg/n.

Heat transfer body: Width: 1 m, length: 2 m, inlet water temperature: 25°C, water supply amount: 24 J/H, exit water: 1=6o0C When continuous vibration was applied, there was no change even after 2 hours had passed. Increase the number of royal orders to 2
; There was no problem even if I lowered it to 5 Hz. 10 every 10 minutes
Similarly, there was no decrease in thermal efficiency even when the ocular organ was activated intermittently for seconds. If this is activated for 1 second, under the same conditions, 4
After 0 minutes, the thermal efficiency decreased from 60% to 52%.

- (Comparative example) When no vibration was applied, the water temperature was 42°C under the same conditions, and the efficiency was 48.

In Example 1, when the water feed rate was reduced to 15 kg/H, hot water easily exceeding 75°C was obtained.

With hot water at such a temperature, it is possible to use stress-corrosion-resistant cracking material as in the example above, and there was no adverse effect of water resistance.In fact, it is easier to remove the bubbles by shaking off the accumulated water by photographing (21). There are advantages.

Example 2 Under the same conditions as Example J, the time required for water to be discharged from the flow path when vibration is applied intermittently, Q, is approximately 1 to 0 seconds (depending on the flow rate, physical properties of the liquid, installation conditions such as the inclination of the device, etc.) When the water flow was stopped and vibration was applied for about 1 second, the thermal efficiency significantly decreased over a period of 2 hours. In other words, it makes weak vibrations, strikes, and pulsations effective.

Example 3 In Example 1, two polyester (PET'l yarns each having a diameter of 0.3 mm) were inserted in parallel in the flow path direction at an interval of 15 mm as an auxiliary channel forming material.

Water outlet temperature increased by an average of 3°C, improving efficiency.

Similarly, the process of forming auxiliary channels by roughening the channel walls and painting the surface had the effect of increasing the liquid temperature by 2 to 3°C on average.

Example 4 In the structure shown in Fig. 4, the support plate 16 was made of zinc (0.5 mIn thick).
22) It was made of iron plate. The heat-receiving surface auxiliary flow path forming recess in the flow path direction had a protrusion height of 0.3 mm on the inner surface -\ and an interval of 20 mm.

In the direction perpendicular to this, with respect to the flow path], a concave press groove was made and the plate surface was reinforced.

The same results as in Example 2 were obtained.

Actually, scary example 5: An electromagnetic vibrator was attached to 4i in Fig. 7, and a device similar to that in Example 1 was assembled. The liquid distribution unit was reinforced by inserting a distributor pipe in place of the liquid seal gasket shown in Figure 11. The power of the shaker is 20W.

There was no change in efficiency over time.

14 kg/h of hot water (75°C) is obtained with an efficiency of 6.
It was 0%. The inlet water temperature was 25°C.

Example 6 The device shown in FIG. 9 was assembled with the same turning specifications as Example 1. The diaphragm 34 had a diameter of 1.00 mm and was made of rubber.

As for the vibrator, the one from Example 1 was reused.

Under the same conditions as in Example 5] 6 kg/H of pumped water (75°C) was obtained and the efficiency was 68φ.

The efficiency when no vibration was applied was 53%.

(23) Vibrated in Example 7. The lower end of the insert may be fixed to the outlet flow path pipe 8, or may have a shape from which another rod or the like is suspended. An elastic body such as a spring may be added near the lower end to facilitate vibration. 27 itself may be an elastic body or have restorability.

It was carried out under the same conditions as in Example 3 with an efficiency of 60 to 64%.

(Comparative example) When the vibration was intense, the efficiency under the same conditions was 56=59%.

Example 8 The heat receiving surface of Commercial Example 6 was made of black polyester film (thickness: 0.0510 m), and the rest was assembled with a vibration system as shown in Figure 14, and the thermal efficiency was 63% under the same operating conditions.
75°6 hot water was obtained.

(Comparative example) When no vibration was applied, the efficiency decreased as the time reached 1, and reached 1%'l (+50%) at 2.

(24) Above, we have mainly described the case where water is heated using the upper surface as a solar heat receiving surface with a dark color such as black (it may also be a selective absorption surface). A similar effect can be obtained in the case of a thin plate-like object, such as a film, which may have a transparent coloring. Furthermore, even if the liquid is colored in any way, the flow path blockage due to bubbles and residual gas, and the accompanying heat transfer obstruction, which causes a decrease in efficiency, can occur in the same way, so the present invention can be used effectively. I can do it.

As explained above, the present invention can be used with a plate (2) at least on one side of which is a thin plate-like material, curved, flat or corrugated, or a combination thereof.

Since it is a thin plate-like layer, it is lightweight and reduces the amount of material used, and uses high-grade corrosion-resistant or abrasion-resistant materials and highly durable materials, which were conventionally expensive and difficult to use. made it possible to do so.

Such materials include stainless steel, copper, titanium, fluorine plastic, and fluorine rubber. On the other hand, it is possible to manufacture highly efficient and easy-to-build products, so it can be used as a portable solar water heater, a heating or cooling surface for rooms, water tanks, etc., or a heat exchanger for a large amount of fluid. This allows it to be assembled using inexpensive materials.

Therefore, the applications are not only for small household water heaters, but also for agricultural greenhouses, industrial uses, wastewater (for laboratories, watering from irrigation, etc.)
This makes it possible to use an inexpensive and highly efficient device with a thin-layer flow path in a water heater or heat exchanger, thereby helping to reduce energy consumption.

In addition, applying vibration to the flow channel according to the present invention also prevents water, aqueous solutions, and suspensions from settling in the flow channel or scaling on the flow channel walls in channels where the flow velocity is relatively low, such as a falling film type flow channel. Since it also has the effect of preventing a decrease in efficiency, the effect of preventing a decrease in efficiency is enhanced from this aspect as well.

Bubble prevention measures include a mutual combination of the above-mentioned measures,
Other methods such as antifoaming agents (foam inhibitors, etc.) or application to the heat transfer surface of rollers may be used in combination.

In this manner, the present invention makes it possible to manufacture highly efficient and inexpensive solar water heaters by applying vibration to the heat transfer channel.
