As shown in FIG. 1, which is an embodiment of the present invention, each thermoelectric module 600 is coupled to the fluid transfer channel unit 300 and the lubricating oil transfer channel unit 500, but the fluid transfer channel unit 300 is necessarily. ) And the thermoelectric module 600 need not be coupled to each of the lubricating oil transfer channel parts 500, and the thermoelectric module 600 is coupled to only the fluid transfer channel part 300 or the lubricating oil transfer channel part 500 according to an embodiment. You can also

As mentioned above, the low temperature fluid transfer channel 310 and the low temperature lubricating oil transfer channel 510 and the low temperature panels 311 and 511 formed in each have similar functions and configurations, and have a high temperature fluid transfer channel 320 and a high temperature lubricant. The transfer channel 520 and the high temperature panels 421 and 521 formed in each of them have similar functions and configurations, so that the low temperature fluid transfer channel 310 and the high temperature fluid transfer channel 320 are respectively described below to avoid duplication of explanation. A combination of the low temperature panel 311 and the high temperature panel 321 will be described.

However, in order to avoid confusion in the description below, the low temperature transfer channel 310 of the fluid transfer channel unit 300 is defined as a low temperature fluid transfer channel 310, and the high temperature transfer channel of the fluid transfer channel unit 300 ( 320 will be defined as the high temperature fluid transfer channel (320).

In addition, the low temperature transfer channel 510 of the lubricating oil transfer channel part 500 is defined and used as the low temperature lubricating oil transfer channel 510, and the high temperature transfer channel 520 of the lubricating oil transfer channel part 500 is a high temperature lubricating oil transfer channel ( 520).

The coupling relationship between the fluid transfer channel unit 300, the low temperature fluid transfer channel 310, the high temperature fluid transfer channel 320, and the thermoelectric module 600 will be described in detail with reference to FIG. 2. .

The outer circumferential surface of the low temperature fluid transfer channel 310 is coupled to the low temperature panel 311 which is in thermal contact with the low temperature portion 610 of the thermoelectric module 600, and the high temperature portion of the thermoelectric module 600 is connected to the outer circumferential surface of the high temperature fluid transfer channel 320. The high temperature panel 321 in thermal contact with the 620 is coupled.

At this time, the low temperature fluid transfer channel 310 formed on the outer circumferential surface of the low temperature panel 311 and the high temperature fluid transfer channel 320 formed on the outer circumferential surface of the low temperature panel 311 are radiated by the fluid radiator 200. And a high temperature fluid endothermic by the engine 100 flows, so a temperature difference is generated between the low temperature fluid transfer channel 310 and the high temperature fluid transfer channel 320 to which the low temperature panel 311 and the high temperature panel 321 are coupled. Done.

The thermoelectric module 600 in thermal contact with the low temperature fluid transfer channel 310 and the high temperature fluid transfer channel 320 using the temperature difference is proportional to the temperature difference between the low temperature fluid transfer channel 310 and the high temperature fluid transfer channel 320. Electrical energy is generated.

Thus, in order to increase the electrical energy generated by the thermoelectric module 600, the cooling fins 3111 are coupled to the low temperature panel 311, and the heat insulation panel 3211 is coupled to the high temperature panel 321.

The cooling fins 3111 are for increasing the surface area of the ambient air in contact with the low temperature fluid transfer channel 310, and protruding cooling fins 3111 are formed on one side of the low temperature panel 311.

When the temperature of the fluid, which is cooled and transferred from the radiator 400, rises again by the thermoelectric module 600 and flows into the engine, the temperature of the engine may increase. In this case, the cooling fins 3111 also serve to cool the fluid flowing into the engine.

The cooling fins 3111 may be manufactured to cover the entire low temperature panel 311 by increasing the surface area of the low temperature panel 311 in contact with the surrounding air, but a cooling fin of this type (not shown) is formed. In this case, the low temperature portion 610 of the thermoelectric module 600 is coupled to the low temperature panel 311 with the cooling fins 3111 interposed therebetween, so that the low temperature portion 610 of the thermoelectric module 600 has a higher temperature when it is directly in thermal contact with the low temperature fluid transfer channel 320. Causes problems.

Therefore, the cooling fin 3111 is preferably formed only on the upper surface of the low temperature panel 311, as shown in FIG. ) Is preferably formed flat so that the low temperature portion 610 of the thermoelectric module 600 is in close contact.

In addition, it is preferable that a heat insulation panel 3211 is formed on the high temperature panel 321 coupled to the outer circumferential surface of the high temperature fluid transfer channel 320.

When the heat insulation panel 3211 is formed, since the high temperature fluid transfer channel 320 exchanges heat through the ambient air and the high temperature panel 321, the amount of heat exchange with the ambient air is reduced.

Therefore, the high temperature panel 321 is insulated and can be in thermal contact with the high temperature portion 620 of the thermoelectric module 600 with the temperature attracting the temperature.

The heat insulation panel 3211 may be formed to cover the entire outer circumferential surface of the high temperature panel 321, but in this case, the high temperature portion 620 of the thermoelectric module 600 may be the high temperature panel 321 through the heat insulation panel 3211. Thermal contact.

In this case, the high temperature portion 620 of the thermoelectric module 600 has a problem that the temperature is lower than the direct contact with the high temperature panel 321 is formed.

Accordingly, in order to generate a large temperature difference between the low temperature portion 610 in contact with the low temperature panel 311 and the high temperature portion 620 in contact with the high temperature panel 321, the heat insulation panel 3211 may be formed in the high temperature panel 421. It formed only at the bottom.

The shape of the heat insulating panel 3211 in the present embodiment is not necessarily limited to such a shape, and may be modified in various forms as long as it meets the purpose of blocking heat exchange between the high temperature panel 321 and the outside.

In addition, the low temperature fluid transfer channel 310 forming the fluid transfer channel part 300 may be formed of a plurality of tubes, but when the low temperature fluid transfer channel 310 is formed of one tube, the low temperature fluid transfer channel 310 It is preferable that a plurality of septums (septum, 312) is disposed inside the low temperature fluid transfer channel 310 to allow maximum heat exchange with the periphery.

The diaphragm 312 according to the present invention partitions the inside of the low temperature fluid transfer channel 310 to increase the contact area between the fluid flowing in the low temperature fluid transfer channel 310 and the low temperature fluid transfer channel 310. The diaphragm 312 according to the present invention increases the surface area between the low temperature panel 311 coupled to the low temperature fluid transfer channel 310 and the fluid flowing in the low temperature fluid transfer channel 310 to provide a space between the fluid and the low temperature fluid transfer channel. Increase the amount of heat exchange

A plurality of small channels surrounded by the diaphragm and the low temperature fluid transfer channel or a small channel surrounded by the diaphragm may be formed in the low temperature fluid transfer channel 310 in which the diaphragm 312 is installed. That is, the inside of the low temperature fluid transfer channel 310 may be divided into a plurality of small channels according to the arrangement of the diaphragm 312. Fluid is transported through these small channels.

In the present embodiment, a plurality of diaphragms 312 are installed in parallel to each other, and a technical configuration of partitioning into small channels having a rectangular pillar shape has been proposed. In the case of the embodiment of FIG. 3, a low temperature fluid transfer channel 310 is disclosed that includes a plurality of small channels formed with a plurality of diaphragms 312 spaced in parallel.

The high temperature fluid transfer channel 320 may be formed of a plurality of small channels, such as the low temperature fluid transfer channel 310, but when the high temperature fluid transfer channel 320 is formed of one channel, the high temperature fluid transfer channel 320 is coupled to the high temperature fluid transfer channel 320. The high temperature fluid transfer channel (410) is the same as the low temperature fluid transfer channel 410 so that the temperature of the high temperature unit 610 of the thermoelectric module 600 is close to the temperature of the high temperature fluid flowing inside the high temperature fluid transfer channel 320. It is preferable to arrange a plurality of septums 322 inside 320.

The plurality of diaphragms 322 may be arranged in various forms inside the high temperature transfer channel 320, and a small channel having a plurality of various forms is formed according to the arrangement form.

In this embodiment, a plurality of diaphragms 322 are installed in parallel with each other, and a technical configuration of partitioning into complex channels having a square pillar shape has been proposed. 3, a hot fluid transfer channel 320 is disclosed that includes a plurality of small channels formed with a plurality of diaphragms 322 spaced in parallel.

The membranes 312 and 322 formed inside the low temperature fluid transfer channel 310 and the high temperature fluid transfer channel 320 may be formed in various shapes, but are shown in FIG. 3 to generate a minimum resistance to the flow of the fluid. As described above, the low-temperature fluid transfer channel 310 and the high-temperature fluid transfer channel 320 are spaced apart from each other to communicate with one side of the fluid inflow and the other side of the fluid outflow.

Since the diaphragm is formed to be substantially parallel to the flow of the fluid, when the fluid flows in the low temperature fluid transfer channel 310 and the high temperature fluid transfer channel 320, the resistance is minimally generated.

When a plurality of diaphragms 312 and 322 are formed in the low temperature fluid transfer channel 310 and the high temperature fluid transfer channel 320, the thermoelectric module 600 may be a low temperature fluid transfer channel 310 or a high temperature fluid transfer channel ( It may be in thermal contact anywhere on the outer side of 320.

However, when the low temperature fluid transfer channel 310 is in thermal contact with the outer wall of the low temperature fluid transfer channel 310 and the high temperature fluid transfer channel 320, which are connected to the diaphragm formed inside the high temperature fluid transfer channel 320, the low temperature fluid transfer channel 310. Heat exchange with the fluid flowing in the 310 and the high temperature fluid transfer channel 320 can be more smoothly.

Therefore, the thermoelectric module 600 is preferably in thermal contact with the outer wall of the low temperature transfer channel 310 or the high temperature transfer channel 320 connected to the diaphragms 312 and 322.

In this embodiment, the fluid transfer channel part 300 includes one low temperature fluid transfer channel 310 and a high temperature fluid transfer channel 320 having a plurality of diaphragms 312 and 322 therein, but one low temperature fluid. It does not have to be made of the transport channel 310 and the hot fluid transport channel 320, it may be composed of a plurality of cold fluid transport channel 310 and the hot fluid transport channel (320).

In the present embodiment, the diaphragms 312 and 322 are formed in both the low temperature fluid transfer channel 310 and the high temperature fluid transfer channel 320, but the diaphragm is formed in both the low temperature fluid transfer channel 310 and the high temperature fluid transfer channel 320.
