Description

Technology Field

[0001] The present invention relates to a thermal management monitoring system and a control method thereof, and more specifically, to a thermal management monitoring system and a control method thereof that can recover a certain portion of waste heat generated from a heat source in an environmentally friendly manner without generating carbon dioxide (CO2) by utilizing thermoelectric power generation, and can continuously monitor the system by determining whether there are any abnormalities due to changes in the temperature of the heat source. Background Technology

[0003] The thermoelectric phenomenon was first discovered by the German physicist T.J. Seebeck. It is a phenomenon in which an electric current or voltage is generated when different temperatures are applied to the junction between two different conductors in a circuit; the flow of heat moving from a hot area to a cold area generates an electric current. This phenomenon is called the Seebeck effect.

[0004] Jean-Charles Athanas Peltier of France discovered another important thermoelectric phenomenon, which is the phenomenon in which, when a direct current flows through a circuit made of different conductors, one side of the junction between the different conductors heats up while the other side cools down depending on the direction of the current. This is called the Peltier Effect.

[0005] William Thomson revealed that the existing Peltier effect and Seebeck effect are related and summarized the correlation between them; in this process, he discovered the Thomson effect, which states that if a potential difference is applied to both ends of a single conductor rod, heat absorption or release will occur at both ends of the conductor.

[0006] Thermoelectric elements, known by various names such as thermoelectric modules, Peltier elements, thermoelectric coolers (TECs), and thermoelectric modules (TEMs), are small heat pumps (devices that absorb heat from a low-temperature heat source and transfer it to a high-temperature heat source). When a DC voltage is applied across the terminals of a thermoelectric element, heat moves from the heat-absorbing part to the heat-generating part; consequently, over time, the temperature of the heat-absorbing part drops while the temperature of the heat-generating part rises. At this point, if the polarity of the applied voltage is reversed, the heat-absorbing and heat-generating parts are swapped, and the heat flow is also reversed.

[0007] A typical thermoelectric device consists of a pair of N-type and P-type thermoelectric semiconductor elements as its basic unit. When a direct current (DC) voltage is applied across the terminals, heat is transferred according to the flow of electrons in the N-type and holes in the P-type, causing the temperature of the heat-absorbing portion to decrease. This is based on the principle that because there is a difference in the potential energy of electrons within the metal, electrons must obtain energy from the outside to move from a metal with lower potential energy to a metal with higher potential energy; consequently, thermal energy is lost at the junction, while in the opposite case, thermal energy is released. This heat absorption (cooling) is proportional to the flow of current and the number of thermoelectric couples (a pair of N- and P-type elements).

[0008] Significant amounts of heat are generated from heat sources such as melting furnaces and incinerators in steel mills, thermal power plants, heat supply stations like district heating companies, and their pipelines; therefore, it is necessary to recover a certain portion of this heat in an environmentally friendly manner. Furthermore, since abnormalities in heat sources can lead to dangerous situations, the development of a monitoring system is required. Prior art literature

[0050] Thermoelectric elements exhibit the Seebeck effect, in which an electromotive force is generated when a temperature difference is applied across the ends of the element, and the Peltier effect, in which a temperature difference is generated when a potential difference is applied.

[0051] These thermoelectric devices can directly convert thermal and electrical energy using thermoelectric power generation, which utilizes the Seebeck effect that generates voltage when a temperature difference is applied between the two ends of a material, and thermoelectric cooling, which utilizes the Peltier effect where one side heats up and the other side absorbs heat when a direct current is applied between the two ends of a material.

The P-type semiconductor device (P) and the N-type semiconductor device (N) may have the same shape or size, but the volume of one may be formed differently from the volume of the other semiconductor device facing each other. For example, the volume can be increased by forming the diameter of the N-type semiconductor device larger than the diameter of the P-type semiconductor device, thereby improving the thermoelectric efficiency.

It is preferable that the second substrate (120) have a thickness of about 0.1 to 1 mm. If the thickness of the second substrate (120) is thinner than 0.1 mm or exceeds 1 mm, the heat dissipation characteristics may be excessively high or the thermal conductivity may be too high, which may reduce the reliability of the thermoelectric element (100).

[0080] Masking is performed to form a second electrode layer (150) on a second substrate (120). Masking can be performed by applying a photoresist that leaves the area where the second electrode layer (150) is to be formed open and shields the other parts.

It is preferable that the thickness of the second electrode layer (150) be about 0.01 to 0.5 mm. If the thickness of the second electrode layer (150) is less than 0.01 mm, the electrical conductivity may be poor, and if it exceeds 0.5 mm, the conductivity efficiency may be lowered due to an increase in resistance.

The thermoelectric system (10) compares the power generated from the thermoelectric module (200) and, when a temperature change is detected in the heat source, wirelessly transmits an alarm signal (alm) containing information regarding the temperature change of the heat source to the gateway (20). The alarm signal (alm) is a signal containing information regarding the temperature change of the heat source and can be used as a basis for determining whether there is an abnormality in the temperature of the heat source.

[0090] The monitoring unit (40) displays data transmitted from the data server (30) so that the user can see it, or sounds an alarm (more specifically, a warning sound).

[0091] The thermoelectric system (10) may measure a change in the temperature of a heat source and wirelessly transmit an alarm signal (alm) regarding the change in the temperature of the heat source to the gateway (20), or may generate power using the heat generated from the heat source.

When a temperature difference (ΔT) is applied between the first substrate (110) and the second substrate (120), the thermoelectric module (200) generates power (V ax The thermoelectric module (200) generates power (V) according to the temperature difference between the first substrate (110) and the second substrate (120). ax Can generate ).

[0095] The control unit (300) measures the power generated from the thermoelectric module (200) to measure the temperature change of the heat source and receives the thermoelectric power.

[0096] When a temperature difference (ΔT) is generated between the first substrate (110) and the second substrate (120) by the above heat source, the thermoelectric module (200) converts thermal energy into power (V ax Converts to ), and the above power (V ax ) outputs to the control unit (300). When a temperature difference (ΔT) is generated between the first substrate (110) and the second substrate (120), the control unit (300) outputs the power (V) generated by the thermoelectric module (200). ax ) can be transferred to other components of the thermoelectric system (10). For example, the control unit (300) can transfer power (V) generated by the thermoelectric module (200). ax ) can be transferred to an operation indicator (500) that displays the operating status of the thermoelectric system (10), or to a battery (600) of the thermoelectric system (10). Thermal energy generated between the first substrate (110) and the second substrate (120) can be transferred to electrical energy (power (V)) using a thermoelectric module (200). ax It can be converted into )) and the converted electrical energy can be utilized as an energy source for other components that require power. From this, waste heat generated from the heat source can be efficiently utilized using the thermoelectric system (10), and industrial waste heat generated from the heat source can be recovered to some extent.

[0097] Power (V) generated from the thermoelectric module (200) ax ) is transferred to the converter (310), and the converter (310) transmits the power (V axIt converts ) and outputs the converted power. The converter (310) may be a DC-DC converter, and the power (V ax It can boost the voltage and output the converted power.

[0098] The control unit (300) can transmit power received through thermoelectric power generation to the operation display unit (500). The operation display unit (500) can display the operation status of the thermoelectric system (10). For example, the operation display unit (500) may include a light-emitting diode (LED). The operation display unit (500) may receive the necessary power from the control unit (300) or may receive the necessary power from the battery (600).

[0099] The control unit (300) can transfer power received through thermoelectric power generation to the battery (600). The battery (600) receives power from the control unit (300) to store energy, and if necessary, can supply power to other components of the thermoelectric system (10) (e.g., operation indicator (500), etc.).

[0100] The power sensing unit (320) senses or detects power input from the thermoelectric module (200) to the converter (310) and compares the power input to the converter (310) with a preset reference value. The power sensing unit (320) compares whether the power input to the converter (310) exceeds the preset reference value. Multiple reference values ​​can be set. For example, the reference values ​​can be set as a first reference value and a second reference value. The reference values ​​can be set by a user.

[0101] The wireless transmission module (400) transmits an alarm signal (alm) wirelessly under the control of the control unit (300). The wireless transmission module (400) can vary the magnitude and / or frequency of the transmitted alarm signal (alm).

The wireless transmission module (400) serves to wirelessly transmit information about the power sensed or detected by the power sensing unit (320) to the gateway (20). If the result of comparison by the power sensing unit (320) exceeds a reference value, it indicates that an abnormality has occurred in the heat source differently from usual. In such cases where an abnormality has occurred in the heat source differently from usual, and information regarding the alarm signal (alm) is processed by the monitoring unit (40) through the gateway (20) and the data server (30), an alarm (alarm), such as a warning sound or a lamp, can be activated according to the alarm signal (alm) transmitted by the wireless transmission module (400). When the above alarm is activated, the user can recognize that an abnormal temperature has been detected in the heat source where the thermoelectric module (200) is placed.

[0103] When multiple reference values ​​are set, a first control signal may be transmitted when the result of comparison by the power sensing unit (320) exceeds the first reference value, and a second control signal may be transmitted when the result exceeds the second reference value. The second reference value is assumed to be a case where a higher power is detected compared to the first reference value. Thus, when the result of comparison by the power sensing unit (320) exceeds the first reference value and the second reference value, it indicates that an abnormality has occurred in the heat source differently from usual, and when the second reference value is exceeded, it indicates that an abnormality has occurred in the heat source more severely than when the first reference value is exceeded. When information regarding an alarm signal (alm) is displayed in the monitoring unit (40) through the gateway (20) and the data server (30), a yellow lamp is activated when a first alarm signal is received according to the alarm signal (alm) transmitted by the wireless transmission module (400), and a red lamp is activated when a second alarm signal is received, thereby further highlighting the dangerous situation so that the user can recognize it. The red lamp is a signal indicating that the situation is more dangerous than the yellow lamp.

[0104] Hereinafter, a control method for a thermal management motorizing system according to a preferred embodiment of the present invention will be described in more detail.

[0105] A thermoelectric module (200) is placed near a heat source to recover waste heat and detect abnormalities due to temperature changes. The thermoelectric module (200) is placed at a location to determine whether there are abnormalities in the heat source and to recover waste heat. A first substrate (110) of the thermoelectric module (200) is positioned on the hot side facing the heat source, and a second substrate (120) of the thermoelectric module (200) is positioned on the cold side opposite the heat source relative to the first substrate (110). When arranged in this way, the temperature of the first substrate (110) closer to the heat source becomes higher than the temperature of the second substrate (120), thereby forming a temperature difference (ΔT). At this time, it is desirable to maintain a constant temperature of the second substrate (120) using a chiller or the like. The above heat source may be a melting furnace, incinerator, thermal power plant, heat supply station, etc., that generates heat, such as in a steel mill, but is not limited thereto, and refers to any substance or place that generates heat, and may additionally include pipes that supply heat.

[0106] When a temperature change in the heat source is detected by comparing the power generated from the thermoelectric module (200), the thermoelectric system (10) including the thermoelectric module (20) wirelessly transmits an alarm signal (alm) containing information regarding the temperature change of the heat source to the gateway (20).

[0107] Below, the control method of the above thermoelectric system is explained in more detail.

[0108] Figure 5 is an operation flowchart for explaining the control method of the thermoelectric system.

[0109] Referring to FIG. 5, it is determined whether a temperature difference (ΔT) has occurred between the first substrate (110) and the second substrate (120) (S100).

[0110] When a temperature difference (ΔT) occurs between the first substrate (110) and the second substrate (120), thermoelectric power generation using the thermoelectric system (10) is operated (S200). When a temperature difference (ΔT) is generated between the first substrate (110) and the second substrate (120) by a heat source, the thermoelectric module (200) converts thermal energy into electricity (V ax Converts to ), and the above power (V ax ) outputs to the control unit (300). Power (V) generated from the thermoelectric module (200) ax ) is transferred to the converter (310).

[0111] It is determined whether the temperature of the first substrate (110), which is the hot side, is lower than the reference temperature (S300). Whether the temperature of the hot side is lower than the reference temperature can be determined through the power sensing unit (320). The power sensing unit (320) senses or detects the power input from the thermoelectric module (200) to the converter (310) and compares the power input to the converter (310) with a preset reference value. By comparing the power input to the converter (310) with the reference value, it can determine whether the temperature of the hot side is lower than the reference temperature. If the power input to the converter (310) is lower than the preset reference value, it is determined that the temperature of the hot side is lower than the reference temperature, and if the power input to the converter (310) is higher than the preset reference value, it is determined that the temperature of the hot side is higher than the reference temperature. Multiple reference values ​​determined by the power sensing unit (320) may be set, for example, as a first reference value and a second reference value. The above reference value can be set by the user.

[0112] As a result of determining whether the temperature of the first substrate (110), which is the hot side, is lower than the reference temperature, if the temperature of the hot side is lower than the reference temperature, thermoelectric power generation power can be received (S400). The thermoelectric system (10) receives power (V) generated by the thermoelectric module (200). ax ) can be used. Power (V) generated from the thermoelectric module (200) ax) is transferred to the converter (310), and the converter (310) transmits the power (V ax It converts ) and outputs the converted power. The converter (310) converts the power (V ax ) can be boosted and output as converted power. The control unit (300) can output the power (V) generated by the thermoelectric module (200). ax ) can be transferred to other components of the thermoelectric system (10). For example, the control unit (300) can transfer power (V) generated by the thermoelectric module (200). ax ) can be transferred to an operation indicator unit that displays the operating status of the thermoelectric system (10), or to the battery (600) of the thermoelectric system, etc. Thermal energy generated between the first substrate (110) and the second substrate (120) can be transferred to electrical energy (power (V)) using the thermoelectric module (200). ax It can be converted into )) and the converted electrical energy can be utilized as an energy source for other components that require power. From this, waste heat generated from the heat source can be efficiently utilized using the thermoelectric system (10), and a certain portion of industrial waste heat generated from the heat source can be recovered.

[0113] As a result of determining whether the temperature of the first substrate (110), which is the hot side, is lower than the reference temperature, if the temperature of the hot side is greater than the reference temperature, the wireless transmission module (400) transmits information regarding this (S500). The power sensing unit (320) senses or detects the power input from the thermoelectric module (200) to the converter (310) and compares the power input to the converter (310) with a preset reference value. By comparing the power input to the converter (310) with the reference value, it can determine whether the temperature of the hot side is greater than the reference temperature. If the power input to the converter (310) is greater than the preset reference value, it is determined that the temperature of the hot side is greater than the reference temperature. Multiple reference values ​​determined by the power sensing unit (320) may be set, for example, a first reference value and a second reference value. The reference values ​​may be set by the user. The wireless transmission module (400) transmits an alarm signal (alm) compared by the power sensing unit (320). The wireless transmission module (400) serves to wirelessly transmit information about the power sensed or detected by the power sensing unit to the gateway (20). If the result of the comparison by the power sensing unit (320) exceeds a reference value, it indicates that an abnormality has occurred in the heat source differently from usual. In such cases where an abnormality has occurred in the heat source differently from usual, and information regarding the alarm signal (alm) is processed by the monitoring unit (40) through the gateway (20) and the data server (30), the alarm can be activated according to the alarm signal (alm) transmitted by the wireless transmission module (400). When the alarm is activated, the user can recognize that an abnormal temperature has been detected in the heat source where the thermoelectric module (200) is placed. When multiple reference values ​​are set, a first control signal may be transmitted when the result of comparison by the power sensing unit (320) exceeds the first reference value, and a second control signal may be transmitted when the result exceeds the second reference value. The second reference value is assumed to be a case where a higher power is detected compared to the first reference value.In this way, when the result of comparison by the power sensing unit (320) exceeds the first reference value and the second reference value, it indicates that an abnormality has occurred in the heat source differently from usual, and when the second reference value is exceeded, it indicates that an abnormality has occurred in the heat source more severely than when the first reference value is exceeded. When information regarding the alarm signal (alm) is displayed in the monitoring unit through the gateway (20) and the data server, the yellow lamp is activated when the first alarm signal is received according to the alarm signal (alm) transmitted by the wireless transmission module (400), and the red lamp is activated when the second alarm signal is received, thereby highlighting the dangerous situation further so that the user can recognize it. The red lamp is a signal indicating a more dangerous situation than the yellow lamp.

[0114] As a result of determining whether the temperature of the first substrate (110), which is the hot side, is lower than the reference temperature, if the temperature of the hot side is lower than the reference temperature, thermoelectric power generation power is received (S400), and it is determined whether a temperature difference (ΔT) is detected between the first substrate (110) and the second substrate (120) (S600). If it is determined that a temperature difference (ΔT) is detected, steps S300 to S500 can be performed repeatedly, and if it is determined that a temperature difference (ΔT) is not detected, the process can be terminated.

[0115] The gateway (20) receives an alarm signal (alm) transmitted wirelessly from the thermoelectric system (10) and transmits it to the data server (30) via a wire.

[0116] The data server (30) analyzes the received alarm signal (alm) and outputs data to the monitoring unit (40).

[0117] The monitoring unit (40) displays the data transmitted from the data server (30) so that the user can see it, or sounds an alarm (more specifically, a warning sound).
