Heating and cooling device with split circulation path {Heating and cooling device with split circulation path}

The present invention relates to a heating and cooling device having a divided circulation path, and more particularly, in order to maximize the heat transfer characteristic efficiency of a thermoelectric element, water It relates to a heating and cooling device having a divided circulation path including a jacket, a radiator, and a pump, including a heat exchange divided circulation path for cooling and heating.

In general, a heat exchange equipment (heat exchange equipment) is a device that efficiently transfers heat from a high-temperature object to a low-temperature object, and is used to transfer heat such as liquid, gas, and solid.

These heat exchangers are used for heating or cooling purposes, and include heaters, coolers, condensers, etc. in a broad sense, but are usually used for the purpose of emitting or recovering heat. The purpose of the heater is to heat the low-temperature side fluid.

Such a heat exchanger is used in thermal power plants, nuclear power plants, gas turbines, heating devices, air conditioners, refrigerating devices, connection panels for solar power in the chemical industry, inverter switchboards, and the like. Boilers, evaporators, superheaters, condensers, and coolers are all heat exchangers.

The heat exchanger consists of two coaxially arranged tubes with separate inlets and outlets for the two liquids. Cold fluid flows through the inner tube and hot fluid flows in the same direction through the space between the inner and outer tubes. In it, heat is transferred through the walls of the inner tube to the cold fluid.

Taking the cooling or heating structure of a heat exchanger using a conventional thermoelectric element as an example, as shown in FIG. There is this low issue.

In addition, in the case of the conventional heat exchanger, since the high-temperature heating unit and the low-temperature heating unit must be separated from each other and provided with a heat sink and a fan motor, respectively, there is a problem in that the volume space increases and a lot of noise is generated due to the increase in the number of fan motors.

Prior literature related to the above heat exchanger, particularly a heat exchanger or heat exchanger using a thermoelectric element, is as follows.

Document 1: Republic of Korea Registered Utility Model Publication No. 20-0311413 (Name: Hot and cold compress using a thermoelectric element and heat exchanger; Application date: 2002.11.29.)

The present invention according to the above problem solving means transfers heat to the high temperature heating unit 10, that is, a container requiring a high temperature by absorbing heat from the water jacket 1 (11) by the thermoelectric element 1 (12), (10) The heating of the object accommodated in the side container is performed, and the thermoelectric element 2 (22) transfers heat to the water jacket 2 (21) by absorbing heat from the low temperature part 20, that is, from the side of the container requiring low temperature. By allowing the cooling of the object accommodated in the container on the side of the low-temperature section 20 to be performed, through a single circulation path for heat exchange, the high-temperature section 10 and the low-temperature section 20 simultaneously combine high and low temperatures simultaneously. Through diversified heat exchange, the effect of cooling and heating is obtained.

In addition, in the present invention, when the water pump, which is the circulation induction unit 50, supplies the first low-temperature thermal liquid (A ℃) from the radiator, which is the cooling unit 40, to the water jacket 1 (11), the thermoelectric element 1 ( 12) absorbs the heat (α°C) of the thermoelectric body and transfers it to the high-temperature heating unit, so the high-temperature heating unit 10 increases in temperature by adding the heating temperature of the thermoelectric element 1 (12) (A+α°C), is lowered (A-α ° C) and moves to the water jacket 2 (21) where the low-temperature unit 20 is located. As the cooling performance due to the difference (Δt) appears, the second low-temperature thermal liquid from the high-temperature heating unit 10 side takes more heat, and accordingly, the low-temperature heating unit 20 cools the cooling unit 40 Since the primary low-temperature thermal liquid (A ° C) in the phosphorus radiator is cooled by the thermal liquid (A-2α ° C) lower than that supplied, the effect of cooling with increased cooling efficiency is obtained.

In addition, the present invention obtains an effect of more efficiently increasing the temperature of the high-temperature zone and the low-temperature zone of the low-temperature zone by the heat absorbing and dissipating action of the circulation of the thermal liquid.

In addition, the present invention obtains an effect of improving diversified applicability by arranging a plurality of water jackets and thermoelectric elements in series or parallel and providing integrated or individual circulation paths and cooling units for them.

In the basic heat exchanging method of the present invention, the thermal liquid circulates through water jackets and corresponding circulation paths, and at this time, the heat absorbing portion of the thermoelectric element is interviewed on one side of the water jacket, and the thermal liquid flowing into the water jacket At the same time as the temperature of the heat absorbing portion and the temperature of the heat generating portion opposite to the heat increasing portion is increased, the high-temperature heating unit 10 is heated, and the heating portion of the thermoelectric element is interviewed on one side of the water jacket, flowing into the water jacket At the same time as the temperature of the thermal body is raised, the temperature of the heat absorbing portion located opposite to the heating portion is lowered to cool the low-temperature unit 20.

At this time, the high-temperature thermal liquid discharged to the discharge end of the water jacket is introduced into the inlet end of the water jacket in a cooled state by the circulation guide part through the cooling part, and the above-described operation is continued.

The present invention is a device capable of simultaneously heating and cooling the high-temperature heating unit 10 and the low-temperature heating unit 20 with high efficiency.

In the present invention, the thermoelectric element absorbs heat from the water jacket and transfers heat to the high-temperature heating unit 10, that is, a container requiring a high temperature, thereby heating the high-temperature heating unit 10, and the thermoelectric element lowering the temperature. Cooling of the low-temperature section 20 is performed by absorbing heat from the heating section 20, that is, from the side of the vessel requiring low temperature, and transferring heat to the water jacket.

At this time, when the water pump, which is the circulation induction unit 50, supplies the first low-temperature thermal liquid (A°C) from the radiator, which is the cooling unit 40, to the water jacket, the thermoelectric element generates heat (α°C) of the thermal body is absorbed and transmitted to the high temperature unit 10, the temperature of the high temperature unit 10 is increased by adding the heating temperature of the thermoelectric element (A+α°C).

At this time, since the low temperature unit 20 exhibits cooling performance due to the temperature difference (Δt) between both sides of the thermoelectric element due to the nature of the thermoelectric element, the second low temperature thermal liquid from the high temperature unit 10 generates more heat. Accordingly, the low-temperature unit 20 supplies the thermal liquid (A-2α °C) that is lower in temperature than the primary low-temperature thermal liquid (A ° C) supplied from the radiator, which is the cooling unit 40. Since it is cooled by the cooling process, cooling is performed with increased cooling efficiency.

The thermal body, which absorbs heat from the low-temperature unit 20 and becomes high-temperature, is firstly lowered (A°C) by the heat dissipation action (-α°C) of the radiator and the fan motor of the cooling unit 40, and the circulation induction unit 50 ), and is guided to the water jacket where the high-temperature heating unit 10 is located again by the water pump, which is the circulation induction unit 50.
