Description

Boiler device using cooling element {A BOILER DEVICE USING THERMOELEMENT}

The present invention relates to a boiler device using a cold heat element, and more specifically, it is possible to selectively supply hot or cold water by using a thermoelectric effect from a thermoelectric semiconductor that is used in an electrically connected module form. It relates to a cold and hot water boiler device.

Generally, a thermoelectric module is used in the form of a module in which n, p type thermoelectric semiconductors are electrically connected in series and thermally parallel in a π type. When the DC current flows, a temperature difference occurs on both sides of the module due to the thermoelectric effect, and power generation occurs at the same time. In general, the cooling element refers to a solid state heat pump using a cooling effect exhibited by the Peltier phenomenon.

Electronic cooling applications using endotherms in the Peltier phenomenon may vary from semiconductor manufacturing, medical, general civil, telecommunications, and electronics.

On the other hand, Figure 1 shows the structure of the cooling element, as shown in the metal plate (1) (2) having a predetermined interval and the thermal element 3 and the cold element (4) attached thereto a semiconductor having excellent thermal conductivity It is connected by the bridge (5).

As shown in FIG. 2, the cooling element recovers heat from the cooling element 4 and discharges it into the atmosphere while a current flows in the heating element 3 in a plate-shaped state of a predetermined area, thereby releasing the temperature of the heating element 3. Will be raised. At the same time, when the temperature of the cold element 4 is lowered and the temperature of air or water in the vicinity of the cold element is lowered below the atmospheric temperature according to the heat exchange action in the cold element 4, the flow of current is reversed. In this case, the temperature change state of the heating element and the cooling element is changed.

The advantages of the electronic cooling / heating method are as follows.

First, the cooling / heat dissipation rate can be made quickly and the endothermic heat can be changed according to the direction of the current.

Second, since there is no mechanical operating part, it can be operated without noise and vibration.

Third, it can be compact and light weight, so that local cooling / heat dissipation is possible.

Therefore, an object of the present invention is to apply a cooling element having the above-mentioned advantages to the water heating means of the boiler apparatus so as to selectively supply the cooling and heating water according to the heat exchange with the water under an environment of no vibration and noise.

In addition, another object of the present invention is to improve the utilization efficiency of the product by enabling the use as a function such as indoor cooling in the summer as well as winter heating function of the boiler or at the same time.

The above object is a boiler for supplying hot water or cold water by mutual heat exchange with water passing through a heat exchanger provided on a flow path through which water is supplied:

Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in more detail.

3 is a sectional view of a boiler in which a heat dissipation fin is installed in a heat exchanger according to an embodiment of the present invention, FIG. 4 is a sectional view taken along the line A-A 'of FIG. 3, and FIG. Represent each.

First, the configuration of the present embodiment is as follows.

In the drawings presented above, the heat exchanger 10 to achieve the boiler facility of the present invention has a quadrangular cross section as shown in FIG. 4, but this is 4 to 8 angles depending on the capacity of the water to be heated. It can be produced in a variety of forms.

In addition, a plurality of conventional thermoelectric semiconductor cooling elements 11 are installed on each surface of the heat exchanger 10, and the heating element 11a, which is a heat generating portion, faces the inside of the aircraft, and the cooling element 11b, which is a heat absorbing portion, faces the outside of the heat exchanger. To make it work. Each of the plurality of cooling elements 11 is preferably electrically connected in series with each other.

In addition, the inside of the heat exchanger 10 to which the heat element 11a is opposed is formed with a through hole 12 constituting a flow path of water in a state of forming a thermally conductive material, so that water flowing through the through hole 12 is formed. It is possible to warm the water through heat exchange.

In addition, by attaching heat radiating fins 13 to the portions of the cooling elements 11 that are exposed to the outside of the heat exchanger 10, that is, the cooling elements 11 b, the supercooling (ice generation) according to the temperature decrease of the cooling elements 11 b is performed. At the same time, a blower fan 23 is installed as a forced transfer means for forcedly blowing external air to the heat dissipation fin 13 and a guider 20 for guiding the air to be forcedly blown is formed in a flow path. .

As the fluid transported through the guider 20 for heat exchange with the heat dissipation fin 13, water may be used instead of air as necessary. In this case, a water pump or the like may be installed as a forced transport means.

In the drawings, reference numerals 14 and 15 denote water inlets and outlets, respectively.

The heat exchanger 10 configured as described above may be used together with another separate heat exchanger or may be installed alone. As the power is applied to the cold heat element 11 in this state, the heat generation phenomenon may occur in the heat element 11a. This occurs, thereby warming the water flowing into the heat exchanger 10 through the inlet 14 and then supplying hot water to the room through the outlet 15.

In addition, at this time, the endothermic phenomenon occurs in the cold element 11b of the cold element 11 opposite to the outside air, and the heat generation efficiency at the heat element 11a side is brought about by forcibly blowing air into contact with the blower fan 23. It will be possible to further improve.

At this time, the forced air is cooled by heat exchange with the heat radiating fin 13 attached to the cold element 11b, and the cooled air can be guided indoors or outdoors along the guider 20.

When the electrode applied to the cooling element 11 is reversely applied according to the user's needs, the heating portion and the endotherm portion are interchanged with each other. This causes the heating of the cooling element 11 to the inside of the heat exchanger 10 and to the outside. As the endothermic action takes place, the cooling of the incoming water also becomes possible. Thus, it is possible to achieve a boiler of both cold and hot temperatures in which cold water to the indoor side can be supplied.

On the other hand, the experiment for measuring the efficiency of the heat exchanger 10 was performed as follows.

The configuration for this experiment is schematically shown in FIG. 5, and an integrating power meter (not shown), a water storage bucket 21, a circulation pump 22, and a thermometer 24 are additionally provided to measure the result. .

<Experimental Example 1>

-Heat exchanger: 24 cooling elements installed (no heat radiation fin attached)

-Voltage applied: 12V parallel connection

-Water quantity: 800L

-Power meter and temperature change: 1KWH-> 2.25KWH (△ 1.25KWH), 27.5 ℃-> 29.4 ℃ (△ 1.9 ℃)

That is, input KCal: 1.25KWH × 860KCal / KWH = 1075 KCal

Output KCal: 800L × 1.9 ℃ = 1520 KCal

Therefore, in Experimental Example 1, 1520/1075 = due to insufficient heat treatment on the cold element 11b side. 141,4% It was found that the low efficiency of.

<Experimental Example 2>

-Heat exchanger: 24 cooling elements installed (4 radiating fins attached, blower fan operated)

-Voltage applied: 12V parallel connection

-Water quantity: 860L

-Power meter and temperature change: 2.25KWH-> 5.40KWH (△ 3.15KWH), 28.2 ℃-> 33.4 ℃ (△ 5.2 ℃)

That is, input KCal: 3.15KWH × 860KCal / KWH = 2709 KCal

Output KCal: 860L × 5.2 ℃ = 4472 KCal

As a result, by showing an efficiency of 4472/2709 = 165.1%, it was confirmed that the heat exchange effect was increased while the heat exchange efficiency of the cooling element 11b was partially improved by the operation of the blower fan.

<Experimental Example 3>

-Heat exchanger: 24 cooling elements installed (4 radiating fins attached, blower fan operated)

-Voltage applied: 12V series connection

-Water quantity: 860L

-Power meter and temperature change: 5.40KWH-> 6.012KWH (△ 0.612KWH), 33.4 ℃-> 35 ℃ (△ 1.6 ℃)

That is, input KCal: 0.612KWH × 860KCal / KWH = 526 KCal

Output KCal: 860L × 1.6 ℃ = 1376 KCal

After all, the efficiency of 1376/526 = 262%, it was confirmed that the thermal effect is greatly increased by the operation of the blower fan and the application of DC power.

Looking at the results of the above experimental example, when the blowing fan 23 is operated after attaching the heat radiation fins 13 to the cooling elements 11 at predetermined positions, and when the cooling elements 11 are connected in series with each other. It was confirmed that the energy efficiency of the boiler was further improved by heating the water.

On the other hand, as a comparative example, in the case of the conventional boiler device, there was a problem such as noise generation and an increase in the required space because a burner for heating the water should be installed inside the device, but according to the present invention, hot water supply using a cooling element is made. It can be seen that noise does not occur and the appearance of the device can also be slimmed, thereby greatly improving the customer satisfaction of the product.

In addition, by supplying cold air through the air contact from the outside at the same time as the supply of hot water, the cold and hot water is selectively supplied by reversing the applied electrode of the cold heating element as well as in winter, thereby making it possible to use it versatile in summer. Indicates.

In addition, although specific embodiments of the present invention have been described above, it is apparent that the boiler apparatus using the cooling device of the present invention may be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, the water is heated inside the heat exchanger using a cooling element, and the air is contacted on the outside to achieve indoor air conditioning. In addition, the water is not air along the flow path of the outer guider 20. It can be seen that it is possible to change the usage, such as to obtain cold water and hot water at the same time inside and outside the heat exchanger by supplying.

Therefore, these various modified embodiments should not be understood individually from the technical spirit or prospects of the present invention, these modified embodiments should fall within the appended utility model claims of the present invention.

In the boiler of the present invention as described above, in the supply of hot water or cold water by the cooling element, the absorption and heat generation in the boiler are selectively performed according to the direction of the applied current, thereby precisely controlling the temperature of the fluid. This is possible, as the endothermic source for cooling as well as heating of the heating water is obtained from the electric element has an effect that the operation is made noiseless, vibration-free.

In addition, since the boiler body can be made smaller and lighter, the installation and manufacturing efficiency of the product can be improved.

In addition, there is no need to use a refrigerant gas for the use of cooling heat, and thus the advantages such as environmentally friendly characteristics are exhibited.
