BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

As used herein, terms used in the present invention are selected from general terms that are widely used in the present invention while taking into account the functions of the present invention, but these may vary depending on the intention or custom of a person skilled in the art or the emergence of new technologies. In addition, in certain cases, there may be a term arbitrarily selected by the applicant, in which case the meaning thereof will be described in the description of the corresponding invention. Therefore, it is intended that the terminology used herein should be interpreted based on the meaning of the term rather than on the name of the term, and on the entire contents of the specification.

FIG. 1 is a schematic view of a cooling / heating system using a thermoelectric device according to the present invention. FIGS. 2A and 2B are views showing the heat exchanger of FIG. 1, and FIGS. 3A and 3B are views showing a thermoelectric device arrangement of the heat exchanger of FIG. Fig.

As shown in FIG. 1, the heating / cooling system using the thermoelectric device according to the present invention performs heat exchange with water supplied from outside in accordance with a cooling temperature or a heating temperature to fill the heat exchanged water with water at the bottom of a residence or a workplace The heat exchanging unit 10 is disposed adjacent to the heat exchanging unit 10 or inside the heat exchanging unit 10. The heat exchanging unit 10 performs a heat generating function according to the application direction of the DC voltage. And the other side thereof is provided with a plurality of thermoelectric elements 20 which perform a heat absorbing function and an inlet or an outlet end of the heat exchanging part 10 so as to forcibly supply the heat exchanging water to the heat exchanging part 10, A motor pump 30 for forcibly discharging the water heat-exchanged in the heating unit 10 and a radiating fin 40 disposed outside the plurality of thermoelectric elements 20 for improving the heat exchange efficiency of the thermoelectric elements 20, And the radiating fin 40, An electric heating member 50 disposed on the outer side of the heat dissipation fins 40 for applying electric heat to the heat dissipation fins 40 to maximize the heating efficiency and a user input unit 50 for setting the cooling / heating mode, the cold / hot water mode, A three-way valve 70 for selectively controlling the discharge path of the heat-exchanged water discharged from the heat exchange unit 10 according to the setting of the user input unit 60, A control unit 80 for controlling the execution of the operation mode by comparing the set temperature and the current temperature when the operation mode and / or the set temperature set from the user input unit 60 are inputted, (90).

The fan unit 100 may further include a fan coil 100 for blowing cool air using the heat-exchanged water discharged from the heat exchange unit 10 according to the setting of the user input unit 60.

The electric heating member 50 may be selected from the group consisting of electric resistance heating wire, PCT heating element, coil heater, feeding heater, cartridge heater, casting heater, sheathe heater, halogen heater, infrared heater, pin heater, ceramic band heater, And a heating element using electricity is all possible.

In addition, when the plurality of thermoelectric elements 20 cool the water, the temperature of the thermoelectric element is lowered because the function surface of the thermoelectric element absorbs heat and the reaction surface releases heat. At this time, the action surface absorbs heat from the water, so that the temperature of the reaction surface rises continuously while the temperature changes little. However, if the temperature difference between the action surface and the reaction surface increases, the efficiency of the thermoelectric device 20 becomes low. To prevent this, heat can be released through the radiating fins 40 attached to the reaction surface.

On the contrary, when the plurality of thermoelectric elements 20 heat the water, the temperature of the action surface rises and the temperature of the reaction surface rises. At this time, the working surface releases heat to the water, so that the change of temperature is small, but the temperature of the reaction surface continues to decrease. Accordingly, in order to increase the efficiency of each thermoelectric element 20, when the attached electric heating member 50 located on the reaction surface is driven, the temperature of the reaction surface can be increased and the temperature difference with the operation surface can be reduced . As a result, the temperature difference between the working surface and the reaction surface of the thermoelectric element 20 becomes small, and the efficiency of the thermoelectric element 20 can be maximized.

Therefore, the control unit 90 senses the temperature detection value of the temperature detection sensor S10 attached to the output terminal of the heat exchange unit 10 and detects the operation surface and the reaction surface of each thermoelectric element 20 according to the sensed detection value. It is possible to automatically control the optimum heat absorbing or exothermic operation.

In addition, the three-way valve 70 controls the output valve under the control of the control unit 90 so that only the inlet for performing one of the following three operations is opened and the other inlet is closed.

For example, (1) when the user selects the cooling or heating mode, the cooling or heating water heat exchanged in the heat exchanging unit 10 is supplied to the housing or the bottom of the office as a pipe embedded in the heat exchanging unit; (2) (3) When the user selects the cool air mode, the heat exchanged cooling or heating water is supplied to the fan coil 100 ).

The control unit 90 may further include a temperature sensor S10 disposed at an output end of the heat exchanging unit 10 to sense the temperature of the water discharged after the heat exchange. The operation of the plurality of thermoelectric elements 20 can be controlled according to the temperature of the water.

In addition, the driving operation of the electric heating member 50 can be performed through the battery 110 provided in the heating / cooling system using the thermoelectric device according to the present invention, and the battery 110 is provided in the general commercial power, solar heat, Power can be supplied.

2A and 2B are views showing the heat exchanger of FIG. 1; FIGS. 3A and 3B are views showing the arrangement of thermoelectric elements of the heat exchanger of FIG. 1. FIG.

2A and 2B, the flow pipe 12 of the heat exchanging unit 10 may be formed with a plurality of through holes 13 so that the incoming water can be separated into a plurality of flow passages.

The reason why the plurality of through holes 13 are formed is that the heat exchange efficiency of each thermoelectric element 20 can be increased because the introduced water passes through a plurality of flow paths. That is, since water can be supplied as cold water or hot water even with a small electric power, the heat exchange efficiency of each thermoelectric element 20 can be increased.

In Figs. 2A and 2B, the through holes 13 may be regularly arranged, but may be irregularly arranged in some cases.

The heat dissipating fins 40 are disposed outside the thermoelectric elements 20, so that the heat exchange efficiency of the thermoelectric elements 20 can be greatly increased.

Here, the heat dissipation fins 40 may be arranged in a one-to-one correspondence with each thermoelectric element 20.

For example, when the first, second, third, and fourth thermoelectric elements 20a, 20b, 20c, and 20d are disposed outside the flow pipe 12 of the heat exchange section 10, The first radiating fins 40a are disposed in the first thermoelectric element 20a, the second radiating fins 40b are disposed in the second thermoelectric elements 20b, the third radiating fins 40c are disposed in the third thermoelectric elements 20c, And the fourth radiating fin 40d may be disposed on the four thermoelectric elements 20d.

The entire length of the radiating fins 40 may be the same, but they may be formed differently depending on the case.

For example, the heat radiating fins 40 disposed outside the thermoelectric elements 20 are arranged in such a manner that the length of the heat radiating fins 40 located in the central region of the thermoelectric elements 20 and the length of the heat radiating fins 40 located in the edge regions of the thermoelectric elements 20, The lengths of the first and second electrodes 40 may be different from each other.

That is, the length of the radiating fins 40 located in the central region of the thermoelectric elements 20 may be longer than the length of the radiating fins 40 located in the edge regions of the thermoelectric elements 20.

The reason is that the central region of the thermoelectric element 20 is higher or lower in temperature than the edge region of the thermoelectric element 20 and the temperature is uniformly maintained as a whole so that the heat exchange efficiency of the thermoelectric element 20 can be increased Because.

Further, the gaps between the radiating fins 40 may be entirely the same, and the gaps may be different in some cases.

For example, the heat radiating fins 40 disposed outside the thermoelectric elements 20 are arranged in a space between the heat radiating fins 40 located in the central region of the thermoelectric elements 20 and in the edge region of the thermoelectric elements 20 The spacing between the radiating fins 40 may be different from each other.

That is, the distance between the radiating fins 40 located in the central region of the thermoelectric element 20 may be narrower than the distance between the radiating fins 40 located in the edge region of the thermoelectric element 20.

The reason is that the central region of the thermoelectric element 20 is higher or lower in temperature than the edge region of the thermoelectric element 20 and the temperature is uniformly maintained as a whole so that the heat exchange efficiency of the thermoelectric element 20 can be increased Because.

Next, the flow pipe 12 of the heat exchange unit 10 may have a polygonal shape as shown in Figs. 3A and 3B, and each outer surface may have a flat surface.

This is because the outer side of the flow pipe 12 of the heat exchanging part 10 must have a flat plane so that the contact area with the thermoelectric element 20 is widened and the heat exchange efficiency of the thermoelectric element 20 can be increased.

Here, as shown in FIG. 3A, one thermoelectric element 20 may be disposed on one surface 12-1 and 12-2 provided in the flow pipe 12 of the heat exchanger 10. FIG.

The thermoelectric element 20 disposed on each face 12-1 of the flow pipe 12 is electrically connected to the thermoelectric element 20 disposed on the other face 12-2 on the adjacent face 12-2, Or may be connected to at least one of serial and parallel mixing connections.

Alternatively, as shown in FIG. 3B, a plurality of thermoelectric elements 20 may be disposed on one surface 12-1 and 12-2 provided in the flow pipe 12 of the heat exchanging unit 10. FIG.

Here, the plurality of thermoelectric elements 20 disposed on the same surface 12-1 or 12-2 may be electrically connected to each other and may be connected to at least one of a serial connection, a parallel connection, and a serial and parallel hybrid connection have.

In some cases, the plurality of thermoelectric elements 20 disposed on the different surfaces 12-1 and 12-2 are electrically connected to each other and connected to each other by at least one of a serial connection, a parallel connection, or a serial and parallel hybrid connection Can be connected.

The electrical connection method of the thermoelectric elements 20 disposed on the one surface 12-1 may be different from the electrical connection method of the thermoelectric elements 20 disposed on the other surface 12-2.

The electrical connection method of the thermoelectric elements 20 disposed on the one surface 12-1 may be the same as the electrical connection method of the thermoelectric elements 20 disposed on the other surface 12-2.

As described above, the plurality of thermoelectric elements 20 electrically connected in various ways are disposed outside the flow pipe 12 of the heat exchange unit 10, and thus the heat exchange efficiency is high and the energy efficiency is high at a low cost.

In the cooling / heating system using the thermoelectric device according to the present invention configured as described above, a plurality of thermoelectric elements are arranged in at least one of serial and parallel, and cooling / heating can be performed efficiently at a low cost.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
