The n-type galvanic element 7 and the p-type galvanic element 8 are the same in size and are square sheets, the side length of the n-type galvanic element is 4mm, the thickness of the n-type galvanic element is 1mm, and the actual thickness range is slightly larger than or equal to the thickness of the insulating substrate 4 so as to facilitate the subsequent series connection. The single row of the n-type electric couple elements and the p-type electric couple elements 3 consists of 6 pairs of n-type electric couple elements 7 and p-type electric couple elements 8, each pair of the n-type electric couple elements 7 and the p-type electric couple elements 8 consists of one n-type electric couple element 7 and one p-type electric couple element 8, the n-type electric couple elements and the p-type electric couple elements are arranged alternately, and the distance between the adjacent electric couple elements is 2mm, namely the distance between the two adjacent n-type electric couple elements is 8 mm. The n-type galvanic element 7 and the p-type galvanic element 8 can be made of bismuth telluride materials.

The n-type galvanic element and the p-type galvanic element 3 are fixed on the insulating substrate 4 to form a galvanic element part of the power generation system, each galvanic element is inserted in a square small hole corresponding to the insulating substrate 4 in a transition fit manner, in the embodiment, the n-type galvanic element and the p-type galvanic element 3 are in two rows, and the galvanic elements are exposed to the same thickness on the upper surface and the lower surface of the insulating substrate 4.

The single-row hot-layer copper sheet combined module 2 is composed of 7 hot-layer copper sheets 9 which are arranged at intervals and are spaced by 1 mm. The same single-row heat-layer copper sheet combination module 2 is arranged below the insulating substrate 3; two copper sheets on the edge of the single-row thermal-layer copper sheet combined module 2 are respectively in contact connection with an n-type galvanic couple element and a p-type galvanic couple element and are fixed by gluing; each of the other five copper sheets of the single-row thermal-layer copper sheet combination module 2 is respectively contacted with an n-type galvanic couple element and a p-type galvanic couple element, and is fixed by gluing to play a role in electric conduction and heat conduction; every two copper sheets of the single-row hot-layer copper sheet combination module 2 cannot contact with each other.

The single-row cold layer copper sheet combined module 5 is composed of 6 cold layer copper sheets 10 which are arranged at intervals and are spaced by 1 mm. The hot layer copper sheet 9 and the cold layer copper sheet 10 have the same structure and are rectangular sheets, the length is 11mm, the width is 5mm, and the thickness is 0.2 mm; two lines of same single-row cold layer copper sheet composite modules 5 are arranged on the insulating substrate 3; each copper sheet in the 6 copper sheets of the single-row cold-layer copper sheet combined module 5 is respectively contacted with an n-type galvanic couple element and a p-type galvanic couple element, and is fixed by gluing to play a role in electric conduction and heat conduction; every two copper sheets of the single-row cold layer copper sheet combination module 5 cannot contact with each other.

The thermal layer film 1 is mainly coated below two rows of thermal layer copper sheet combined modules 2 and is fixed by gluing.

The cold layer film 6 is mainly coated on the two rows of cold layer copper sheet combined modules 5 and is fixed by gluing.

The thermal layer film 1 and the cold layer film 6 both play an insulating role to form the shell of the thermoelectric generator, so the sizes are just modeling structures matched with the thermoelectric generator, and the thermoelectric generator can be actually expanded, as shown in fig. 7, 3 thermoelectric generators are arranged in parallel, and the size of the thermal layer film is correspondingly expanded. Wherein, the materials of the hot layer film 1 and the cold layer film 6 are both high-heat-conductivity film materials.

The insulating substrate 4 is made of insulating aerogel with extremely low thermal conductivity.

The thermoelectric generator power generation element does not comprise the hot layer film 1 and the cold layer film 6.

The invention enhances the heat utilization rate of the thermocouple materials through series connection, and simultaneously, the adopted insulating substrate 4 has extremely low heat conductivity and less heat loss of the substrate.

Preferably, the upper layer and the lower layer of straight copper sheets are adopted to be beneficial to the conduction of heat energy, structurally, the straight copper sheets cover the surfaces of the two ends of the n-type galvanic couple element and the p-type galvanic couple element, and the insulating substrate with extremely low heat conductivity is adopted to ensure that the heat transmission is mainly concentrated on the galvanic couple element; the copper sheet is selected from materials, and has high electrical conductivity and thermal conductivity and certain flexibility, so that the overall flexibility of the structure is ensured.

Preferably, the galvanic element is located at the center of the insulating substrate 4, which makes the heat loss smaller to achieve the highest energy utilization.

Preferably, the invention adopts the design of two rows of p-type and n-type couple element couple pairs, so as to simplify the model, facilitate the analysis of the structure and the experiment, and have practical significance for multi-row structures.

In fig. 1, the cold layer film 6 is represented by a semi-transparent method to show the arrangement of two rows of cold layer copper plate composite modules 5; meanwhile, the side A and the side B of the thermoelectric generator are marked in the figure, and the side A or the side B can be bent when the thermoelectric generator is worn on the skin surface (such as an arm) of a human body.

As shown in fig. 2, the present invention is composed of a hot layer film 1, two rows of hot layer copper sheet combination modules 2, two rows of n-type galvanic elements and p-type galvanic elements 3, an insulating substrate 4, two rows of cold layer copper sheet combination modules 5, and a cold layer film 6 (the description sequence is from bottom to top). Wherein a single n-type galvanic element 7 is represented in grey and a single p-type galvanic element 8 is represented in black.

Because the sizes of the hot layer film 1 and the cold layer film 6 are flexibly set according to parameters such as the specific line number, the couple pair number and the like of the specific thermoelectric generator, the functions of the hot layer film 1 and the cold layer film 6 are only equivalent to the functions of a shell and have insulating and blocking effects, the hot layer film 1 is contacted with the skin of a human body, and the cold layer film 6 is contacted with the outside, the specific matching relation of the films to the power generation elements of the thermoelectric generator does not need to be proposed; and because of the insulating effect of the film, the boundary of the film is slightly larger than the boundary of the power generation element of the thermoelectric generator, and the boundary of the film can be set to be larger than 3-5 mm.

Fig. 3 is composed of two rows of hot-layer copper sheet combined modules 2, two rows of n-type galvanic couple elements and two rows of p-type galvanic couple elements 3, which form the bottommost layer of the thermoelectric generator generating element, and the specific matching mode is as follows: the n-type and p-type galvanic elements are fixed on the upper surface of the single row thermal layer copper sheet combined module 2 by conductive adhesive, and for the long edge of a single thermal layer copper sheet 9, the n-type and p-type galvanic elements should be symmetrically distributed on two sides of the upper surface of the thermal layer copper sheet 9 (the galvanic elements are distributed on the positions, close to the upper and lower sides, of the thermal layer copper sheet 9 as seen from fig. 3); as shown in fig. 3, the distance between the single p-type galvanic element 8 at the bottom right corner and the three sides of the single thermal-layer copper sheet 9 matched with the single p-type galvanic element is 0.5mm (from fig. 3, the three sides refer to the upper side, the left side and the right side of the copper sheet), and the matching is also used for matching the other p-type galvanic elements in the figure with the thermal-layer copper sheets of the p-type galvanic elements, and for the n-type galvanic element, the three sides are changed into the lower side, the left side and the right side of the copper sheet; the single hot-layer copper sheet 9 at the extreme edge of each row is provided with only one galvanic element, and the redundant length of the galvanic element can be used for connecting the series lead 11 or the parallel lead 12; for the single hot-layer copper sheet 9 in the middle of each row (the single hot-layer copper sheet combined module 2 removes the single hot-layer copper sheet 9 on the extreme edge, as shown in fig. 3, 5 single hot-layer copper sheets 9 are in the middle position in each row), the two rows of 10 copper sheets are respectively matched with a pair of n-type and p-type electric coupling elements, namely a single n-type electric coupling element 7 and a single p-type electric coupling element 8, wherein the single rows of n-type electric coupling elements and p-type electric coupling elements 3 distributed on the upper surface of each row of hot-layer copper sheet combined module 2 are arranged alternately by n-type electric coupling elements and p-type electric coupling elements, namely every two adjacent electric coupling elements are different in type.

Fig. 4 is composed of two rows of hot-layer copper sheet combined modules 2, two rows of n-type and p-type galvanic elements 3 and insulating substrates 4, and two rows of cold-layer copper sheet combined modules 5. It is by the structure that figure 3 cooperates, earlier with insulating substrate 4 cooperation, again with the cooperation of two lines of cold layer copper sheet composite module 5, concrete cooperation mode as follows: as shown in fig. 2, the insulating substrate 4 is perforated, and the length and width of the perforation are exactly the same as those of the galvanic element, but the thickness model of the insulating substrate 4 is set to be 0.6mm slightly smaller than the thickness of the galvanic element by 1 mm. The electric couple element penetrates through the substrate, the insulating substrate 4 can be arranged in the middle of the electric couple element, namely the distance between the upper surface of the insulating substrate 4 and the lower surface of the cold-layer copper sheet combined module 5 is equal to the distance between the lower surface of the insulating substrate 4 and the upper surface of the hot-layer copper sheet combined module 2, and the structure shown in fig. 4 is formed by matching the upper cold-layer copper sheet combined module 5. As can be seen from fig. 4, the distribution of the cold layer copper sheet combination modules 5 and the hot layer copper sheet combination modules 2 are just staggered when viewed from the side, so that each galvanic element only connects one single hot layer copper sheet 9 and one single cold layer copper sheet 10, which enables each pair of n-type and p-type galvanic elements in each row to achieve the series connection purpose. It should be emphasized that the single row cold layer copper sheet combination module 5 and the single row n-type electric coupling element and p-type electric coupling element 3 are connected in the same manner as the single row hot layer copper sheet combination module 2 and the single row n-type electric coupling element and p-type electric coupling element 3. A pair of n-type and p-type galvanic elements should be symmetrically distributed on both sides of the lower surface of the single cold layer copper sheet, as shown in fig. 4, the single n-type galvanic element 7 and the single p-type galvanic element 8 are marked to be matched with a single cold layer copper sheet 10, and the left side of the single n-type galvanic element 7 marked on the left side of the figure is 0.5mm away from the left side of the single cold layer copper sheet 10; the right side of the single p-type galvanic element 8 marked on the right of the figure is 0.5mm from the right side of the single cold layer copper sheet 10 in the figure.

Fig. 5 is an oblique top view of the structure of fig. 4 with the insulating substrate 4 removed and the serial conductor 11 added, i.e., fig. 5 is composed of the serial conductor 11, two rows of hot-layer copper plate composite modules 2, two rows of n-type and p-type electric coupling elements 3, and two rows of cold-layer copper plate composite modules 5. The purpose of removing the insulating substrate 4 is to more clearly show the series connection principle of two rows of electric coupling elements through the hot-layer copper sheet combined module 2, the single-row cold-layer copper sheet combined module 5 and the series connection lead 11. The positive and negative poles of each row of galvanic elements are also indicated, where the positive sign "+" indicates the positive pole and the negative sign "-" indicates the negative pole, each row having its own positive and negative poles. As shown in the figure, the p-type galvanic element is represented by black and the n-type galvanic element is represented by gray according to the power generation principle, so that the leftmost side of the first row (as shown in fig. 5, the leftmost galvanic element of the row is gray) is the negative electrode of the row, the rightmost side is the positive electrode of the row, and similarly, the leftmost side of the second row is the black p-type galvanic element, and at this time, the leftmost end of the second row is the positive electrode of the second row, and the rightmost side is the negative electrode of the row; and then the cathode of the first row is connected with the anode of the second row by using a series lead 11, namely the purpose of series connection between rows is achieved. When the negative electrode of the first row and the positive electrode of the second row of the model are connected, the single thermal-layer copper sheet 11 at the leftmost side of the first row and the single thermal-layer copper sheet at the leftmost side of the second row are connected by the series lead 11, meanwhile, the connection is realized according to the type of the galvanic couple element at the most edge of each row in practical application, the flexible processing is realized, and the model is only arranged as shown in the figure.

For fig. 6, two rows of galvanic couple pairs are connected in parallel in a parallel manner, and similarly, the insulating substrate 4 is removed from fig. 6, so as to more clearly show the parallel principle of the two rows of galvanic couple pairs. The difference between fig. 5 and fig. 6: the two rows of galvanic couple pairs in fig. 6 are arranged in the same order (different from the part in fig. 5, the leftmost sides of the two rows in fig. 5 are galvanic couple elements of different types), that is, the leftmost sides of the two rows in fig. 6 are both p-type galvanic couple elements and both positive electrodes; the rightmost sides are all n-type galvanic elements and are all negative electrodes. Thus, by the parallel principle, it is possible to obtain: two parallel wires 12 are required to connect the positive and negative electrodes of the two rows, respectively, i.e., the positive sign "+" indicates the positive electrode and the negative sign "-" indicates the negative electrode, as shown in the figure. It is emphasized that the left-most element type is only used to illustrate the series or parallel principle, and is not limited to the series or parallel mode.

Fig. 7 is a top view of a combination of 3 thermoelectric generators arranged in parallel and a large thermal film, wherein the 3 thermoelectric generators can be connected in series by using series wires 11 or in parallel by using parallel wires 12, and the specific wires are not shown in the figure, so as to show that the thermoelectric generators can be extended in series or in parallel when expanded in the transverse direction. The specific matching relationship among the thermoelectric generators is as follows: the insulating substrates 4 of adjacent thermoelectric generators are connected, and because of the insulating effect of the insulating substrates 4, the work of the adjacent thermoelectric generators is not influenced mutually. The 3 thermoelectric generators are arranged in parallel only for vividly expressing the specific structure of the thermoelectric generators in the multi-row arrangement, as shown in fig. 7, the size of the hot layer film 1 can be flexibly set according to the number of rows of the prepared specific thermoelectric generators, the effect is only shell and insulation, the film is in contact with human skin, similarly, the cold layer film 6 and the hot layer film 1 have the same effect, the cold layer film 6 is not shown in fig. 7, only the matching relation of the thermoelectric generators with the multi-row structure is expressed, and the information of connection of more insulating substrates 4 is expressed at the same time. In the case of actually manufacturing the structure of the side-by-side thermoelectric generator shown in fig. 7, it is also possible to manufacture the insulating substrate 4 as a large block, instead of separately, since the insulating substrate itself has flexibility, so that the flexibility is not so much affected.

The working principle and the use mode of the invention are given as follows: the invention is similar to a novel flexible human body wearable thermoelectric generator which can dissipate heat and store energy through a human body and is applied to human body medical treatment and health monitoring. The heat dissipated from the surface of the skin of a human body is converted into electric energy through the couple element couple pairs, and the heat utilization rate of the couple element couple pairs can be enhanced through connecting the p-type couple element couple pairs and the n-type couple element couple pairs in series through the cold layer copper sheet combination modules and the hot layer copper sheet combination modules.

The specific working mode and the energy transfer process are as follows: the heat energy is transferred from bottom to top, penetrates through the high-heat-conduction heat layer film 1 made of the insulating material, then is transferred to the two rows of heat layer copper sheet combined modules 2, and is conducted through the heat layer copper sheet combined modules 2, and because the insulating substrate 4 is a heat insulating material, most of heat energy is remained near the heat layer copper sheet combined modules 2, and the hot ends of the two rows of n-type and p-type electric couple elements are formed; meanwhile, the corresponding cold ends are formed as follows: because the environment is a cold source, the two rows of cold layer copper sheet composite modules 5 are tightly attached to the lower surface of the high-thermal-conductivity cold layer film 6, and form the cold ends of the n-type electric coupling element and the p-type electric coupling element 3; therefore, the structure enables two ends of the n-type galvanic couple element 7 and the p-type galvanic couple element 8, namely the upper end and the lower end in space, to respectively form a cold end and a hot end of the thermoelectric generator, one end is the hot end facing inwards, the other end is the cold end facing outwards, and then temperature difference is generated, the temperature difference enables each pair of the n-type galvanic couple element 7 and the p-type galvanic couple element 8 to generate a carrier migration phenomenon, because of the series connection of the copper sheets, the carrier migration effects of each pair of the n-type galvanic couple element 7 and the p-type galvanic couple element 8 can be superposed, if wearable sensing equipment and electronic circuits with power of a few muW are externally connected, such as ultra-low power radio, watches and the like, a loop can be further formed, current can be generated, finally converted electric energy can be measured through experiments and is in a micro watt level.

The invention is explained by taking an example that two rows of p-type galvanic couples and n-type galvanic couples are arranged alternately, in a specific embodiment, two rows of p-type galvanic couples and n-type galvanic couples are connected in series through copper sheets to form a flexible human body wearable thermoelectric generator, each row of the flexible human body wearable thermoelectric generator is provided with 6 pairs, and each pair consists of an n-type galvanic couple element and a p-type galvanic couple element. The present invention does not exclude the protection of a thermoelectric generator provided with more or less pairs of couple structures per row, nor of a thermoelectric generator of different sizes, such as larger or smaller p-n type couple elements or thicker or thinner, nor of a thermoelectric generator of other shapes than rectangular p-n type couple elements having the same or similar power generation effects.

For the specific dimensions of all the parts in the specification of the invention, the dimensions of all the parts such as the thermal layer film 1, the single copper sheet of the single-row thermal layer copper sheet combined module 2, the single galvanic element of the n-type galvanic element and the single galvanic element of the p-type galvanic element 3, etc. are the dimensions of the model of the drawing of the specification, and the dimensions of all the parts are uncertain in practical application, so that the patent also protects the thermoelectric generators with the same structure but different dimensions; the protection coupling element and the copper sheet are connected in a conductive adhesive connection mode; meanwhile, the invention also protects different connection modes between rows, as shown in the attached figure 7 of the specification, wherein 3 thermoelectric generators are arranged in parallel (the rows can be electrically connected in parallel or in series) in the figure 7; the invention provides a schematic structural diagram of adjacent rows connected in series, as shown in fig. 5; the invention also provides a schematic diagram of a structure that adjacent rows are connected in parallel, as shown in fig. 6.

Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the claims of the present invention.
