Description

Thermoelectric generator and method of manufacturing the same

The present invention relates to a thermoelectric generator and a method of manufacturing the same.

A thermoelectric element is a device that uses the thermoelectric phenomenon to convert thermal energy into electrical energy or electrical energy into thermal energy due to a temperature difference between both sides. A thermoelectric generator is a device that uses these thermoelectric elements to convert heat into electricity and recover power.

This thermoelectric generator consists of a high-temperature heat exchange fin that exchanges heat with the high-temperature exhaust gas inside, and a low-temperature heat exchange fin through which low-temperature coolant flows outside the thermoelectric generator. In order to increase the efficiency of the thermoelectric generator, the high heat energy of the exhaust gas flowing inside is converted into thermoelectric energy. It must be efficiently delivered to the device.

However, the heat exchange fin of the high temperature part used in the related art does not sufficiently transfer the heat energy of the exhaust gas to the thermoelectric element, which causes a problem in that the efficiency of the thermoelectric element is reduced and the ability to recover power is reduced.

In addition, the problem with the conventional high-temperature heat exchange fin is that the temperature of the exhaust gas entering the inside is high at the inlet and heat exchange occurs as it moves toward the outlet, so the temperature of the exhaust gas decreases. Accordingly, the efficiency of the thermoelectric element placed at the inlet increases due to the large temperature difference, but the efficiency of the thermoelectric element placed at the outlet decreases due to the small temperature difference, making it difficult to obtain uniform efficiency throughout the thermoelectric element.

In addition, the heat exchange fins of conventional thermoelectric generators have the problem of reducing the efficiency of the thermoelectric element because the heat energy of the exhaust gas is not sufficiently transferred to the thermoelectric element, and the efficiency of the thermoelectric element due to the temperature difference at the inlet and outlet is large.

And, the second wall portion 232 may include a second supply area 242 that supplies fluid to proceed in the second direction 223 within the second flow path area 220, but is limited thereto. That is not the case.

The first flow path area 210 is an area made of louver fins configured to direct air toward the upper right, that is, 1 o'clock with respect to FIG. 4, and the second flow path area 220 directs air toward the upper left, that is, 11 o'clock. It means an area made up of louver fins.

In relation to this, Figure 4 shows a structure in which the first flow path area 210 and the second flow path area 220 are arranged one by one. However, when at least two first flow path regions 210 and second flow path regions 220 are arranged alternately, the first distribution guide 310 and the first wall portion 231 provide a plurality of first supply channels. They communicate with each other through the area 241, and the second distribution guide 320 and the second wall portion 232 may have a structure in which they communicate with each other through a plurality of second supply areas 242.

If the first supply area 241 is not present, considering the direction of air flowing into the first flow area 210, which is the front of the heat exchange unit 200, the air moves toward the upper right, so there is The air becomes relatively thin, and as a result, heat exchange may not be performed smoothly in the upper left portion of the first flow path area 210. However, through the first supply area 241, heat exchange can be actively performed by allowing air to flow into the upper left corner where air is thin.

The second supply area 242 can also be applied in the same way, and in Figures 4 and 5, the first supply area 241 and the second supply area 242 are arranged adjacent to the dotted line based on the dotted line in the center. , the positions of the first supply area 241 and the second supply area 242 are formed so as to supply air in the first direction 213 and the second direction 223, and the first distribution guide 310 and the second It may be determined by the distribution guide 320 and may include at least one.

At this time, as the air passing through the first flow path area 210 and the second flow path area 220 is concentrated in a specific direction, there may be an area where the air flowing in from the first flow path area 210 is thin. Since the area where the air is thin occurs naturally as the introduced air moves in a specific direction (for example, the first direction), heat exchange may not occur smoothly in the area where the air is thin.
