On the other hand, in the present invention, the water jackets may be a block body in which a heat exchange member is provided in a hollow path that allows heat exchange with a thermoelectric liquid flowing in a fixed state in contact with the thermoelectric elements.

On the other hand, in the present invention, the cooling unit and the cooling units may be a radiator or a radiator equipped with a fan motor.

On the other hand, in the present invention, the circulation induction units may be a water pump equipped with a water pump and a water tank.

The operation of the present invention as described above will be described as follows.

First, the present invention is a circulation path 1 (P1) that provides a path through which the thermoelectric liquid sequentially circulates with respect to the water jackets 1, 2 (11, 21) arranged in series, as shown in FIGS. 2 to 4 of the accompanying drawings. ; a heating unit 10 including a thermoelectric element 1 (12) that absorbs heat from the water jacket 1 (11) and generates heat; a lowering unit 20 including a second thermoelectric element 22 for cooling operation by transferring heat to the second water jacket 21; a cooling unit 40 disposed on the water jacket 2 21 side of the circulation path 1 (P1) to lower the temperature of the high-temperature thermoelectric liquid; a circulation induction unit 50 disposed between the water jacket 1 11 and the cooling unit 40 in the circulation path 1 (P1) to induce forced circulation of the thermoelectric liquid; It is a heat exchange device comprising a.

As described above, in the present invention, the discharge end of the water jacket 1 (11) and the inlet end of the water jacket 2 (21) are connected, and the discharge end of the water jacket 2 (21) and the inlet end of the water jacket 1 (11) are connected. The thermoelectric liquid circulates through the path 1 (P1). At this time, the heat absorbing portion of the thermoelectric element 1 (12) is surfaced on one side of the water jacket 1 (11), and the thermoelectric liquid flows into the water jacket 1 (11). At the same time as lowering the temperature of the heat absorbing part, the temperature of the heating part located opposite to the heat absorbing part is heated to heat the high-temperature part 1, and the heat of the thermoelectric element 2 (22) on one side of the water jacket 2 (21) The part is interviewed to increase the temperature of the thermoelectric liquid flowing into the water jacket 2 (21), and at the same time, the temperature of the heat absorbing part located opposite to the heat generating part is lowered to cool the low temperature part (1).

At this time, the high-temperature thermoelectric liquid discharged to the discharge end of the water jacket 2 (21) is cooled while passing through the cooling unit (40), and the inlet end of the water jacket 1 (11) is cooled by the circulation induction unit 50 and continues the same operation as above.

As an exemplary application, the present invention is an apparatus capable of simultaneously heating and cooling a high-temperature part 1 (high-temperature container) and a low-temperature part 2 (low-temperature container) with a single heat exchange device with high efficiency.

According to the present invention, the thermoelectric element 1 (12) absorbs heat from the water jacket 1 (11) and transfers heat to the high temperature part 1, that is, to the container requiring high temperature, whereby the high temperature part 1 is heated. and the thermoelectric element 2 (22) absorbs heat from the low temperature part 2, that is, from the side of the container requiring low temperature, and transfers heat to the water jacket 2 (21), thereby cooling the low temperature part 2 .

At this time, when the water pump, which is the circulation inducing unit 50, supplies the thermoelectric liquid (A°C), which has been reduced primarily from the radiator which is the cooling unit 40, to the water jacket 1 (11), the thermoelectric element 1 (12) is Since the heat (α ℃) of the thermoelectric liquid is absorbed and transferred to the high temperature part 1, the high temperature part 1 increases the temperature by adding the heat generation temperature of the thermoelectric element 1 12 (A + α ℃), and the thermoelectric The liquid is cooled (A-α°C) and moves to the water jacket 2 (21) where the cryogenic unit (2) is located.

At this time, since the low temperature part 2 shows cooling performance due to the temperature difference (Δt) on both sides of the thermoelectric device 2 22 due to the characteristics of the thermoelectric device, the thermoelectric liquid that has been lowered secondarily from the high temperature part 1 side A larger amount of heat is taken, and accordingly, the cryogenic unit 2 has a lower temperature than that of the primary low-temperature thermoelectric liquid (A ℃) supplied from the radiator which is the cooling unit 40 (A-) 2α°C), so that cooling is achieved with increased cooling efficiency.

The thermoelectric liquid, which has been heated by absorbing heat from the cryogenic unit 2, is first lowered to a lower temperature (A°C) due to the heat dissipation action (-α°C) of the radiator and fan motor, which is the cooling unit 40, and the circulation induction unit 50 ), and is guided to the water jacket 1 (11) where the high temperature part (1) is located by the water pump which is the circulation induction part (50).

According to the present invention, the high temperature of the high temperature part 1 and the low temperature of the low temperature part 2 can be made more efficiently due to the heat absorption and heat dissipation action by the circulation of the thermoelectric liquid.

For reference, the thermoelectric liquid is a liquid with the highest heat transfer properties with a specific heat of 1 by adding anti-corruption and antifreeze components to distilled water.
