Integrated system of Exhaust Heat Recovery System and Thermo-Electric Generation system, and operating method thereof

The present invention relates to an integrated system of a heat exchange device and a thermoelectric generator, and an operating method thereof, and more particularly, to a heat source and cooling water temperature in addition to an exhaust heat recovery function that increases the temperature of cooling water by recovering heat energy of exhaust gas with a heat exchange device A system that maximizes the efficiency of the thermoelectric generator by controlling it's about how

Interest in a power generation system using a thermoelectric element as a waste heat source, that is, a thermoelectric power generation system, is increasing, and a heat exchange device that recovers heat energy of exhaust gas from a vehicle and quickly heats coolant to improve fuel efficiency and exhaust characteristics is in the spotlight. The heat exchange device has a limitation in being used only when the vehicle is initially started or when the coolant temperature is low, and the heat exchange device is disposed together with or connected to the thermoelectric generator.

As an example, as in Korean Patent Registration No. 1270627 ("thermoelectric power generation using vehicle exhaust gas and exhaust heat recovery device"), the exhaust gas inlet part through which the vehicle exhaust gas flows into the exhaust heat recovery device, and the exhaust heat recovery device An exhaust gas discharge unit for discharging the introduced exhaust gas to the outside, a first exhaust gas flow path that communicates the exhaust gas inlet and the exhaust gas discharge unit, is formed on the outer surface of the first exhaust gas flow path, and the coolant moves therein a first cooling water flow path, a first thermoelectric module arrangement layer formed on an outer surface of the first cooling water flow path and a thermoelectric module having a cooling element in contact with the outer surface of the first cooling water flow path, the first thermoelectric module arrangement layer; A second exhaust gas flow path formed on an outer surface and installed in contact with the heating element of the thermoelectric module, the exhaust gas inlet and exhaust gas outlet communicating with each other, and the first exhaust gas flow path and the second exhaust gas flow path are selectively selected It is a configuration that includes an opening and closing door that opens and closes with

According to the conventional invention, an exhaust gas flow path for thermoelectric power generation and an exhaust gas flow path for exhaust heat recovery are separately formed, and both thermoelectric power generation and exhaust heat recovery are performed with one device by selectively opening and closing the exhaust gas flow path by an opening/closing door. configuration that can be done.

Accordingly, the conventional invention has a problem in that it is difficult to efficiently operate both systems as the systems having two different characteristics are arranged in one space by selectively performing heat exchange and thermoelectric power generation in one device.

For example, in the case of a thermoelectric power generation system, it is important to efficiently cool the thermoelectric element as the cooling water passes through the corresponding space, and the heat exchanger must be designed so that the heat energy of the exhaust gas can be efficiently transferred to the cooling water. In some cases, it should be composed of a long flow path or a heat dissipation fin to increase the heat exchange area.

In addition, in both devices, a high effect can be expected only when the exhaust gas and cooling water are evenly distributed inside the device to flow. However, the existing system increases the number of thermoelectric elements and configures low aspect ratio exhaust and cooling channels in order to secure a heat transfer area, so the flow distribution is not well done, so thermoelectric power generation efficiency is lowered, and thermoelectric elements are placed between the exhaust pipe and the cooling water channel. It has a structure that does not conduct heat exchange well.

At this time, when the exhaust heat recovery device and the thermoelectric generator are spatially separated, there is an advantage in manufacturing and maintenance, but the space utilization is not good, such as using the exhaust heat recovery device temporarily and the number of thermoelectric generator devices is limited. There is a downside to falling.

Therefore, an integrated system considering the characteristics of the two systems is required.

However, the heat insulating material is applied to a portion that does not come into contact with the thermoelectric element 430 , and may be for reducing the loss of heat source energy.

In general, the thermoelectric element 430 has both surfaces of a high-temperature portion and a low-temperature portion, and a surface close to the heat source is a high-temperature portion, and a surface close to the cooling water is a low-temperature portion. In addition, the greater the temperature difference between both surfaces at this time, the greater the amount of power generation. However, the thermoelectric element 430 may have a different temperature at which the performance can be maximized depending on the material, and the temperature difference may also vary accordingly.

The high temperature limit temperature of the thermoelectric element 430 is affected by the temperature range in which the performance of the device is reduced (about 300° C. in the case of a Bi-Te material, the melting point of the solder, and the limit temperature of a thermal interface material (TIM)) As a result, there is a limit to the maximum temperature of the high temperature part of the device. When cooling the device using cooling water, the temperature of the low temperature part is determined by the cooling water temperature and is about 80~90℃ in consideration of the durability of the heat source part 100, etc. Therefore, in the conventional system, the amount of power generation of the thermoelectric element 430 is determined by the difference between the exhaust gas temperature and the cooling water temperature, or the difference between the maximum limit temperature of the thermoelectric element 430 and the cooling water temperature.

In this case, the cooling water target temperature may refer to a cooling water temperature within a range that does not decrease in terms of durability and performance of the heat source unit 100 .

12 for explaining this is a cross-sectional view of the thermoelectric generator 400 according to the second embodiment of the present invention.

Referring to FIG. 12 , the thermoelectric generator 400 includes: a high-temperature element 450 provided around the outer periphery of the tube 10 separated into two parts; and a low-temperature device 460; wherein one surface of the high-temperature device 450 and the low-temperature device 460 has a second thermoelectric power generation coolant channel 470 and a third thermoelectric power generation coolant channel 480 in contact with each other. can be

For example, the low-temperature device 460 is typically Bi-Te, and may be applied to the present invention.

The tube 10 may be provided with a fourth means 10a at a point where it is divided into two parts.

The fourth means 10a may be configured as a valve, and may be implemented in various ways as long as it is a means capable of controlling the flow of a heat source in the direction of the high-temperature element 450 or the low-temperature element 460 .

Here, the first means 310 , the second means 21 , the third means 410 , and the fourth means 10a may be a valve with an adjustable opening/closing amount, and various types of valves may be applied. can be carried out.

Accordingly, the second embodiment of the thermoelectric generator 400 of the present invention is a system using a thermoelectric generator for low temperature on one side and a thermoelectric generator for high temperature on one side by branching the tube 10, and exhaust gas temperature conditions Accordingly, the fourth means 10a may be used to control the amount of exhaust gas flowing therein. In addition, in the thermoelectric generator 400 , the exhaust gas is converted to the low temperature device 460 in a range where the exhaust gas temperature is low or the efficiency of the low temperature device 460 is high through the exhaust temperature control function of the heat exchange device 300 .

Accordingly, the thermoelectric power generation device 400 may have an extended temperature range for thermoelectric power generation.

Here, if the cooling water temperature is intentionally lowered, additional power generation can be obtained according to an increase in the temperature difference between the heat source temperature and the cooling water temperature. At this time, when cooling water having a lowered temperature is introduced into the heat source unit 100 , it affects the durability of the heat source unit 100 , so that a part of the cooling water is sent to the heat dissipation means 200 or the heat exchange device 300 ), after compensating for the temperature, by introducing it into the heat source unit 100 , it is possible to increase the amount of power generation without affecting the heat source unit 100 . In order to lower the temperature of the cooling water, losses such as the need to increase the size of the heat dissipation means 200 or increase the operating RPM of the fan occur. can

In the existing system, when the heat resistance limit temperature or the power generation performance reduction temperature of the thermoelectric element 430 is reached (about 300° C. in the case of a Bi-Te element), the heat source is bypassed to protect the element so that power generation cannot be made. Alternatively, it can be introduced into a high-temperature device to generate power. Here, the thermoelectric power generation stop portion of FIG. 21 may be referred to as a thermoelectric power generation cliff (TEG cliff). On the other hand, in the system of the present invention, when the exhaust gas temperature increases, the heat exchange device 300 controls the exhaust gas temperature to generate additional thermoelectric power (dashed line). ), the area (hatched lines) excluding the use of a pump for cooling additional coolant or a fan for cooling additional coolant may be a net gain part. However, when the thermal energy of the exhaust gas enters an area outside the capacity of the heat exchange device 300 , the temperature of the exhaust gas is unavoidable. The device may be protected by bypassing, or power generation may be performed using the high-temperature device 450 .
