Definitions
- It relates to electric water heaters, liquid heaters, and steam generators.
- aluminum nitride is used as a partition plate to heat water or liquid.
- Seed heaters have good waterproof properties and are often used around water.
- the prior application was 5.2 KW
- the silicon carbide plate had a diameter of 30 cm, so that the 2 KW of the present invention was five times larger than the 54 square cm. Therefore, this was not a technology to start heating in a few seconds, even if silicon carbide aluminum nitride was used.
- a line of heater that heats the heating wall of a fluid container containing water or liquid inside is formed of a thin metal plate with high electrical resistance as long as the shape can be maintained independently, and electricity is sandwiched between the heating wall and the heating wall.
- the insulator is made of aluminum nitride, etc., which has a thermal conductivity three times higher than that of heater wires.
- the heating wall was made of copper, silver or the like having a heat conductivity higher than that of the heater wire by 10 times or more, and they were heat-conductively adhered to each other.
- FIG. 1 is a perspective view of a water heater according to an example of the present invention, from which a heat insulating coating holder 1 is removed.
- 2A to 2E are new front views of experimental examples and the like showing the relationship between heater wires, insulating plates, and heating walls for understanding the principle of the present invention, and
- FIG. 3 shows heating walls and aluminum nitride plates having different shapes.
- FIGS. 4 and 5 are side views of a fluid container of another application example. BEST MODE FOR CARRYING OUT THE INVENTION
- FIG. 1 is a perspective view of a short tubular water heater 1 according to an example of the present invention, in which a holder for heat insulation is removed for easy understanding.
- the fluid container 2 is a short tube made of copper with a thickness of 1 mm, and both ends are formed into a flare, and a flare nut 3 is fitted so that it can be connected to the front and rear pipes.
- a part between them is formed as a heating wall 4 so as to form a regular hexagonal prism with a side of 10 mm, a 0.6 mm aluminum nitride thin plate 5 is superimposed on the plane, and a heater line 6 is superimposed. .
- Heater wire 6 can be made by quenching an iron-chromium alloy metal plate appropriately, tempering it and strengthening it, reducing the thickness to 0.1 mm, for example, 2 mm as shown in Fig. 1. Even in a zigzag shape in which the gap is 0.5 mm and the gap is 0.5 mm and the gap reciprocates in a 10 mm width, the shape can be maintained autonomously.
- Mitsui ⁇ f is not Ru function in thermal barrier coating holder of all, for example, covered with a heat insulating material of the glass fibers, compressing by winding a tape of silicone rubber, it may be waterproof in co one king material.
- the heater line 6 When the current is sent at 8 A, the heater line 6 generates heat, but ⁇ : the heat is absorbed by the closely packed aluminum nitride plate 5 whose thermal conductivity is about 8 times higher, and the heat is further reduced to about 2. It is absorbed by 5 times the copper heating wall 4. One second after the current starts to flow, heat is transmitted to the inner wall, and after 3 to 5 seconds, the heated water starts to flow.
- the temperature sensors 10 are provided downstream and upstream away from the heating wall, but a mechanical hot and cold water mixer may be provided.
- the area of the hexagonal prism of the heating wall 4 was set to 50 square cm.
- the power density is 40 W per square cm of the aluminum nitride plate.
- it is 5 times more durable than this and its price is high, so it is more convenient to make it smaller.
- the current density of the heater wire 6 is much lower. In consideration of this, safety is enhanced.
- A is A 0.1 mm thick, 2 mm wide iron chrome heater line 11 was stacked on a 4 mm wide, 0.6 mm thick aluminum nitride thin plate 12, and an lmm thick copper plate 13 was further stacked.
- B is obtained by removing the copper plate 13 from A. In these cases, the gap between the heaters was set to about 0.1 mm.
- C is iron chrome of 0.5 mm in diameter with the same cross-sectional area as heater wire 1 1
- Round wire 14 is obtained by laminating aluminum nitride thin plate 12 and copper plate 13 having the same dimensions as above B, and D is obtained by removing copper plate 13 from C. Actually, they were brought into close contact with each other using a 2-mm-thick insulating material made of magnesium oxide and silicic acid as a pressing material from both sides, and a current of 8 A was passed for 1 second.
- the measurement value is not accurate because it is too short, but the copper heater line in Figure 2A
- the surface on the opposite side was about 40 to 50 ° C one second later, and the same surface of copper in C was raised by 1 to 2 "C. Although it is extremely low at 50 to 60 ° C, the C wire 14 is about 100 ° C at the part in contact with the insulation, and the part floating even a little is over 200 ° C. The current flowed for 3 seconds, and one second later, the value was approximately three times the above value.
- the heat generated from 1 is transmitted to the copper plate 13 tens of times faster than from the round wire 14, and the heat is absorbed by the heater 1 1, and the temperature decreases. Furthermore, if there is no copper plate 13, the aluminum plate 1 2 will be heated further and become hot, but the heat of the heat will be small and the heater line 11 will also be hot.
- the heater line must be made thick, for example, about 0.5 mm.
- the thermal conductivity of water is extremely poor, the efficiency of heat conduction from the aluminum nitride plate is higher by boiling, as in a boiler.
- the impact of boiling is also applied, and since it is a liquid, there is a water hammer, and if it becomes a sticky ceramic, it must be made structurally quite strong, and material costs originally Cost is considerably higher.
- the copper plate receives structural strength, the price is 1/50 and the heat conductivity is twice that of aluminum nitride, so the size of aluminum nitride and heater wire is the minimum required If the copper heating wall is widened one by one, that is, if the heat transfer area is widened, the heat conduction to water and liquid will be greatly increased, and the heat will be stored in the wide heating wall. Also. Also, the temperature of the heater line becomes lower, and insulation and waterproofing become easier. In order to increase the heat transfer area, not only the size but also the protrusion ⁇ fin 18 may be submerged or a groove may be cut inside as shown in the heating wall 17 in FIG.
- the aluminum nitride plate 19 has a surface conforming to the quadric surface. Applying an adhesive or grease with high thermal conductivity, which is a mixture of silicon and aluminum nitride fine powder, in the gaps not only enhances the thermal conductivity, but also allows the adhesive to adhere instead of the heat insulation coating holder. Can also be held. The low temperature of the heater wire is also useful here.
- the heating may be performed from the outside, or may be a short tubular heating wall 24 inserted from below as shown by a dotted line in the center of FIG.
- One end of the heating wall 24 is closed, an aluminum nitride plate and a heater are closely attached to the inner wall surface, and insulating and heat insulating materials such as glass cloth and magnesium oxide powder are packed, and the other end is a lead wire 2. 5 is put out, closed, and attached to the floating container 20 through the flange 26.
- This short tubular heating wall 22 is independent of the fluid container with the built-in heater 1 as a single heater. You can also. However, since it is thrown into or put into a floating container, such a shape is also included in the claims of the present application.
- the fluid container may be of various shapes as well as a short tube.
- a rectangular box-like shape 27 as shown in FIG. 5 may be provided with an entrance 28 and a zigzag flowing water path 295 shown by a dotted line inside.
- the facing flat surface is used as a heating wall, and an aluminum nitride plate and a heater may be adhered to it.
- the present invention rapidly heats in a very short time, distortion and fatigue occur, and if the strain accumulates, slippage or breakage occurs and the life is shortened, so that the fluid container expands as uniformly as possible. Shape is desirable.
- the heater line is made zigzag to absorb linear expansion caused by heat.
- the heater line 6 is self-supporting even if it is as thin as 0.1 mm, that is, it can withstand thermal expansion during handling and use even without support such as mica. The shape can be maintained.
- the heater line of the present invention since electric water heaters leak due to water leakage, etc., waterproof specifications are also included in the insulation cover holder.
- the heater line of the present invention since the heater line of the present invention has a low temperature, there are many materials suitable for use, and the most suitable material can be selected. For example, it may be wound with glass cloth and then with silicone rubber, and the gap may be waterproofed with caulking material, or it may be wound with urethane rubber using a new ceramic material.
- a material that can insulate heat while electrically insulating the heater wire from the heating wire and expressing heat as the thermal conductivity shows that it changes with temperature, but rough aluminum nitride at room temperature (10 0 to 20 OW / mK), diamond (200), cBN (130), carbonized £ 1; (270), beryllium oxide (250), etc. is there.
- beryllium oxide is poor in properties, and diamond, cBN and silicon carbide are hard and difficult to process. However, it cannot be used for the present application anyway in the future.
- alumina (20) is the highest in practical ceramics except aluminum nitride, which is about the same as iron chromium, that is, it is one time, so that the effect of the present invention cannot be expected so much.
- aluminum oxide having a thermal conductivity 4 to 5 times that of an iron chromium heater is sufficient to function, and there is no practical ceramic between the two.
- the heating wall may be made of not only copper (370) but also silver (400) having a larger heat capacity if the cost is appropriate. Also, the same effect can be obtained with a ceramic alloy containing these components as a main component, and is therefore included in the scope of the present invention.
- the heating method of the present invention is not only fast but also has a great advantage in that it is simple and low temperature.C Therefore, it can be used not only for instantaneous heating but also for hot water storage instead of the conventional heater, and various liquids It can also be used for heating and warming appliances.
- the use of quick heating can reduce the useless cold water of the instantaneous electric water heater.
- a switch that works by sensing the reduced water pressure by twisting the faucet to discharge water, but separately from it, for example, pressing the switch on the h section of the wash basin by hand, for example, only for 5 seconds
- an extra heating circuit is provided, then
- the time to be set is preferably short enough to wait until the faucet is twisted, and the sensor may be operated not only by pushing the switch by hand but also by standing in front of the sink. If the switch is overheated by pressing the switch more than once, the temperature sensor should detect it and prevent it from heating further.
- the water heater, the liquid heater, and the steam generator of the present invention heat up very quickly, and are energy saving. Water heaters have less waste of cold water and less wasted water when used. Further, the structure for pushing the switch of the present invention a few seconds ago further reduces waste of energy and water. Further, waste of time is reduced.
- the heater line and heating are low temperature and small, it can be kept warm and waterproof, and the equipment Because it is always small, it is also convenient for transportation, for example, it can be used as a water heater for nursing care. It is easy to maintain and has a long service life.
