ものである。 Thermoelectric elements are N-type and P-type semiconductors with excellent thermoelectric performance (ability to convert heat into electricity).
When one surface is heated and the other surface is cooled, an electromotive force is generated between the two surfaces according to the temperature difference. N
The relationship between the heating and cooling surfaces and the direction of the electromotive force is opposite between the type and the P type. Therefore, as shown in Figure 1,
P-type thermoelectric elements P 1 , P 2 , ...... and N of thermoelectric element 1
type thermoelectric elements N 1 , N 2 , ...... are arranged alternately,
Each two adjacent thermoelectric elements are designated as P 1 on the upper side.
N 1 , P 2 and N 2 , ......, N 1 and P 2 , ...... on the lower side
The metal electrode pieces 2 are connected in a staggered manner, and the electrode pieces on one side are heated and the electrode pieces on the other side are cooled. In other words, the P-type and N-type thermoelectric elements are heated. When they are assembled into submodules by connecting them physically in series and thermally in parallel, and heating one side and cooling the other side to create a temperature difference between the two sides, the thermoelectric elements connected to the thermoelectric elements at both ends An electromotive force is generated between the terminals. This direct power generation phenomenon due to heat is
It appears as a result of the close interaction of five fundamental physical phenomena: the Seebeck, Peltier, and Thomson effects, Joule heat generation, and heat conduction.

ることにより任意の発電量を得ることが出来る。 As an example, examples of thermoelectric submodules constructed from bismuth-tellurium thermoelectric elements, which are said to exhibit the highest performance in the ocean temperature range, are shown in FIGS. 2a, b, c, and d. a indicates the top surface, b the front surface, c the bottom surface, and d the side surface of the submodule. The thermoelectric element 1 has a disk shape with a diameter of 13 mm and a thickness of 1.5 mm, and has 10 P-type and N-type elements, a total of 20 elements arranged in two rows as shown in the figure, and each row has P-type and N-type elements. The electrode pieces 2 are arranged in such a way that they are arranged alternately in the transverse direction, and the P type and N type are arranged in parallel in the transverse direction, and the electrode piece 2 made of a copper plate has the P type and the N type arranged in the transverse direction as shown in Fig. 2a on the upper surface. As shown in Figure 2c, on the bottom side, two P type and N type pieces that are adjacent to each other in the longitudinal direction of the module are connected alternately like brickwork, and electrode pieces are connected on the bottom side of both ends. A terminal plate 3 similar to the electrode plate 2 is connected to the lower surface of the thermoelectric element not marked with 2. The electrode plate 2 and the terminal plate 3 serve as both electrical conductors and heat transfer surfaces. In order to heat one surface of the thermoelectric submodule 4 and cool the other surface, for example, as shown in FIG. 3, square tubes 5 and 6, each having a flat outer surface and a cylindrical inner surface, are used as conventional laboratory-scale thermoelectric generators. Used in machine heat exchangers. In FIG. 3, a square pipe 5 is a low-temperature pipe through which cold water flows, and a square pipe 6 is a high-temperature pipe through which hot water flows. The flow directions of cold water and hot water are opposite to each other, so that when heat is exchanged between the low temperature pipe 5 and the high temperature pipe 6 via the thermoelectric submodule 4, the temperature difference is the same everywhere. be able to. By sequentially stacking the above-described low temperature pipe 5, submodule 4, and high temperature pipe 6 in multiple stages, it is possible to obtain an arbitrary amount of power generation.

に必要な海水に対する耐食性が不充分である。 Now, the square heat transfer tube mentioned above is an extruded aluminum alloy section, and in the case of a heat exchanger for a large-scale thermoelectric generator on a practical scale, the size of the tube due to dimensional tolerances during processing or local temperature differences is required. The distortion may cause the tube to separate from the adhesive surface of the thermoelectric module, or the adhesive parts within the thermoelectric submodule, the element itself, and the soldered parts may be damaged due to stress. Furthermore, the corrosion resistance against seawater required for a practical-scale heat exchanger is insufficient.

いる。 In order to improve these drawbacks, as shown in Figure 4, as a heat transfer structure for a large-scale heat exchanger on a practical scale, when copper alloy circular tubes are used as heat transfer tubes for high and low temperatures, one side is An extruded aluminum profile having a concave surface with a substantially semicircular cross section that closely contacts the outer peripheral surface of these circular tubes and a flat surface that closely contacts the electrode piece 2 of the thermoelectric submodule 4 on the other surface was subjected to an electrically insulating alumite treatment. The heat transfer pieces 7 are arranged in the longitudinal direction in a set of two thermoelectric sub-modules 4 (only one thermoelectric sub-module 4 is shown in FIG. 4), and are bonded to the upper and lower surfaces of the thermoelectric sub-modules 4 with a thermally conductive adhesive. It constitutes an integrated submodule unit 8 with a heat transfer unit, and as shown in FIG. 5, a low temperature heat transfer tube 9 is in contact with one of the concave surfaces on both sides of the unit 8, and a high temperature heat transfer tube 10 is in contact with the other concave surface. As shown, heat exchanger tubes 9 and 10
A heat exchanger has been proposed in which heat exchangers and units 8 are alternately stacked and held in multiple stages within a frame structure 11.

生ずる。 According to this configuration, since the thin heat transfer tubes 9 and 10 and the thick heat transfer piece 7 are no longer integrated, they can expand freely, and the above-mentioned drawbacks are improved. However, the contact between the heat exchanger tubes 9, 10 and the heat exchanger piece 7 is made of metal.
However, since there are dimensional tolerances between them, it is impossible for them to contact each other completely without any gaps, and it is inevitable that an air gap will occur. When an air gap occurs, a large heat transfer resistance occurs.

避けることが可能である。 In the present invention, in order to reduce this heat transfer resistance, grease with good thermal conductivity is applied to the joint surfaces of the heat transfer tubes 9 and 10 and the heat transfer piece 7, thereby filling the air gap. , 10 and the heat transfer piece are lubricated to allow free displacement between them. This reduces heat transfer resistance and prevents stress from occurring even if there is a difference in thermal expansion between the two, which in turn makes it possible to avoid damage to the contact parts of the thermoelectric submodule, the element itself, soldering, etc. be.
