Description

The present invention relates to a power generation apparatus that can increase a power generation amount using a thermoelectric conversion element and a thin plate heat device between a heat source and a cooling mechanism of the present apparatus.

Conventionally, as an example of the technology of the thermoelectric conversion element used for this kind of power generation device, there is one disclosed in Japanese Patent Application Laid-Open No. 2003-282972 shown in FIG. Explaining this, thermoelectric elements are roughly classified into thermoelectric conversion elements and Peltier elements. A thermoelectric conversion element is an element that directly converts thermal energy into electric power by using a Seebeck effect that generates a thermoelectromotive force between both ends by giving a temperature difference to both ends of the thermoelectric conversion element. According to the thermoelectric conversion element, different thermoelectric conversion materials of a P-type semiconductor and an N-type semiconductor are placed in parallel, the elements are electrically connected in series, and an external load is connected to form a closed circuit. As a result, a current flows through the circuit and can be taken out as electric power.
In addition, the Peltier element is a closed circuit in which P-type semiconductor and N-type semiconductor different thermoelectric conversion materials are placed in parallel, the elements are electrically connected in series, and an external load is connected. When a current is passed through the circuit in one direction, heat is released or absorbed at the junction between the P-type semiconductor and the N-type semiconductor depending on the current direction. This phenomenon is called the Peltier effect. When the current direction is changed, heat dissipation and heat absorption are reversed. In the Peltier element, the direction of the joint is aligned, and when a direct current is passed, one side of the Peltier element becomes the heat absorption side, that is, the low temperature side, and the other side becomes the heat dissipation side, that is, the high temperature side. In many cases, the heat absorption side is used for cooling or temperature control. The thermoelectric conversion element and the Peltier element have almost the same basic configuration, depending on whether the Seebeck effect is used to generate power or the element is fed and cooled by the Peltier effect.
In the thermoelectric conversion element A, solder layers 3 for bonding are formed on both ends of a pillar 1 made of a P-type semiconductor and a pillar 2 made of an N-type semiconductor, and the pillars are alternately arranged. On the other hand, after the electrode layer 5 is metallized at a desired position on the insulating substrate 4, the solder layer 3 is melted and bonded by reflowing with the insulating substrate 4 having the upper and lower electrode layers 5 formed between the aligned columns. Let Thereafter, the power conducting wire 7 is connected to the lead electrode portion 6 at the end of the Peltier element A to complete the thermoelectric conversion element A. Then, the endothermic side A1 of the thermoelectric conversion element A is attached to the heat source 8 via a material having a high thermal conductivity (not shown) such as heat conduction grease as shown in FIG. The heat absorption side of the thermoelectric conversion element A absorbs heat, and the cooling side A2 of the thermoelectric conversion element A is cooled.
A power generation device in which a thermoelectric conversion element and a heat pipe are combined is disclosed in Japanese Patent Laid-Open No. 2001-282396. A method is disclosed in which one end of the heat pipe is brought into contact with a heat source, one surface of the thermoelectric conversion element is brought into contact with the other end of the heat pipe, and the other surface of the thermoelectric conversion element is brought into contact with a cooling mechanism. However, in this method, the surface area for arranging the thermoelectric conversion element cannot be secured, and the heat resistance of the portion that transports heat is increased by making the cross-sectional shape of the heat pipe square. The temperature of the contact surface does not rise, and sufficient power generation cannot be obtained.
There is one disclosed in Japanese Patent Application Laid-Open No. 2008-143432. Since the cross section of a normal heat pipe is circular and the contact surface of the thermoelectric conversion element is a flat surface, the heat pipe is crushed and formed into a flat surface, or a heat receiving plate is placed between the heat pipe and the thermoelectric conversion element. It is common to provide it. However, in this method, the temperature of the contact surface with the thermoelectric conversion element does not rise as described above, and a sufficient amount of power generation cannot be obtained. Further, in order to bend the heat pipe, a bend R having a diameter of at least about 3 times is necessary, and when the space is narrow, it is necessary to reduce the diameter of the pipe. Therefore, the amount of heat transport is small, and the contact surface with the thermoelectric conversion element is small, so that a sufficient amount of power generation cannot be obtained. Further, in order to increase the contact area with the thermoelectric conversion element, it is necessary to arrange a plurality of heat pipes in parallel. However, it is difficult to obtain flatness with the same shape, and it is difficult to increase the contact area.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a power generator according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a power generation device E as an embodiment of the power generation device according to the present invention.
Prior to the description of the embodiment of the power generation apparatus E according to the present invention, the operation principle of the thermoelectric conversion element applied to the power generation apparatus E according to the present invention will be described in detail with reference to FIG.
The thermoelectric conversion element B is composed of two conductors made of different materials, and when a temperature difference occurs between the thermoelectric conversion elements, current flows through the two conductors due to the Seebeck effect and operates as a power generator. As shown in FIG. 2, the basic configuration of the thermoelectric conversion element B is that a P-type semiconductor element 12 and an N-type semiconductor element are interposed between two insulating heat transfer plates 10a and 10b made of ceramics or the like via an electrode layer 11. 13 are alternately connected and arranged, and are electrically connected in series and thermally connected in parallel. The insulated heat transfer plate 10 b becomes a heat absorption surface, the insulated heat transfer plate 10 a becomes a cooling surface, and a current flows in the direction of the arrow of the lead wire 14.
When a temperature difference is applied to the insulating heat transfer plates 10a and 10b, the thermoelectric conversion element B is a metal N-type semiconductor having different Fermi levels via the electrodes 11a and 11b in contact with the insulating heat transfer plates 10a and 10b. An electric field due to the movement of holes is generated between the P-type semiconductor 12 and the P-type semiconductor 12, and passes through the N-type semiconductor 13 from the lower electrode 11a connected to the lower side of the N-type semiconductor 13 and passes through the upper electrode 11b. An electromotive force is generated in the lower electrode 11a of the type semiconductor 12.
Next, one example of a thin plate heat device applied to the power generation apparatus E according to the present invention will be described in detail based on FIG. 3 and FIG.
FIG. 3 is a plan view of the thin plate heat device 15 partially cut away, and FIG. 4 is a diagram showing the internal structure of the thin plate heat device 15, which is a partially enlarged horizontal sectional view in FIG. is there.
The thin plate heat device 15 is designed to smoothly transport a large amount of heat. The thin plate heat device 15 contains a loop-type meandering small-diameter tunnel heat pipe 16. As shown in FIG. Flow in the direction D to the path 16b. The loop meandering small diameter tunnel heat pipe 16 of the plate heat device 15 needs to have sufficient strength against the internal pressure of the hydraulic fluid 16a. The thin plate heat device 15 satisfying such various conditions is provided with the loop-shaped meandering thin tunnel heat pipe 16 described above in the thin plate 15A.
A group of such unit pairs of loop-shaped meandering small-diameter tunnel heat pipes 16 are connected and communicated with each other, and are configured to be planar and integrated. The group of loop-type meandering small diameter tunnel heat pipes 16 integrated in this way is hermetically sealed together and vacuum degassed, and then a predetermined amount of a predetermined two-phase condensable hydraulic fluid is enclosed. It is made up of heat pipes. In FIG. 4, 15B indicates the position of the heat receiving portion, and 15C indicates the position of the heat radiating portion.
Next, another example of the thin plate heat device applied to the power generation apparatus E according to the present invention will be described in detail with reference to FIG. Reference numeral 17 denotes a thin plate heat device, which is a welded laminate of unit thin plates 18 and flat thin plates 19 made of a metal having good thermal conductivity. Prior to lamination, a series of long meandering narrow grooves 18a are formed on the welding surface of the unit thin plate 18 in advance. The long meandering narrow groove 18a may be formed by any means such as cutting, electric discharge machining, or press molding. The long meandering narrow groove 18a is configured as a closed meandering narrow diameter by stacking, and a predetermined amount of a predetermined working fluid 16a is enclosed in the tight meandering narrow diameter, and the meandering narrow diameter tunnel heat pipe 16 is configured.
FIG. 5 shows an example in which unit thin plates 18 in which long meandering narrow grooves 18a are formed and simple flat thin plates 19 in which no narrow grooves are formed are laminated.
The loop-shaped meandering thin tunnel heat pipe 16 built in the unit thin plate 18 can reduce the radius of curvature of the turn portion to the limit. And it becomes possible to arrange with high density at a pitch that is just the sum of the groove width of about 1 mm to the width of the narrow groove, and it is possible to incorporate a multi-turn thin pipe heat pipe. Therefore, it is possible to construct a plate-type heat pipe with high performance and a small thickness. As an example, when a thin tube heat pipe is incorporated instead of a meandering thin tube heat pipe with an outer diameter of 3 mm and an inner diameter of 2 mm, it is possible to incorporate a 2 mm diameter narrow tube with a pitch of 3 mm, and 33 tubes are arranged in a width of 100 mm. It is possible to construct a plate-type heat pipe having a thickness of 5 mm. The advantage is that less resistance is generated when the hydraulic fluid 16a is circulated and vibrated.
The loop type meandering narrow tunnel heat pipe 16 and the long meandering narrow groove 18a incorporated in the thin plate heat devices 15 and 17 can flow the hydraulic fluid 16a in any installation condition, arrangement form or holding posture. The common advantage is that it has active characteristics. Therefore, in the present invention, the thin plate heat devices 15 and 17 incorporating the loop type meandering thin tunnel heat pipe 16 and the like solve all the problems of the conventional thermoelectric element composed only of the thermoelectric conversion element A. is there. In addition, due to miniaturization, weight reduction, and high density integration of equipment in the IT industry etc., the loop type meandering narrow tunnel heat pipe 16 and the long meandering narrow groove 18a incorporated in the thin plate heat devices 15, 17 The weight and wrinkle are becoming ignorable, and further reduction in size and weight is required, and the present invention can cope with this.
Next, the configuration of the power generator E according to the present invention will be described in detail with reference to FIG. FIG. 1 is a perspective view showing an example of a power generation apparatus E according to the present invention, and illustrates a configuration in which a heat source and a cooling mechanism described later are provided for the sake of understanding. B is each thermoelectric conversion element, and 20 is a thin L-shaped plate heat device. The thin L-shaped plate heat device 20 is formed by bending a metal flat plate into an L shape, and a plurality of thermoelectric conversion elements B are attached to one side of the thin L-shaped plate heat device 20 as shown in FIG. . Here, four thermoelectric conversion elements B are attached, and three or more thermoelectric conversion elements B are attached to the standing part and three base parts. When all the thermoelectric conversion elements B are bonded to the thin L-shaped plate heat device 20, all four bonding surfaces in the plurality of thermoelectric conversion elements B, that is, the insulating heat transfer plate 10b side shown in FIG. For example, it arrange | positions so that it may become an endothermic surface side.
Note that the mounting position, design conditions, arrangement form, holding posture, etc. of the power generator E according to the present invention are not limited to the heat absorption surface side but the cooling surface side depending on the purpose of use. Also good. In this example, the endothermic surface side of each thermoelectric conversion element B is used as the sticking surface. Specifically, one insulating heat transfer plate (corresponding to the insulating heat transfer plate 10a shown in FIG. 2) of each thermoelectric conversion element B is used as a metal flat plate of the thin L-shaped plate heat device 20 (shown in FIGS. 3 and 5). A thin plate 15A and a flat thin plate 19). There are minute gaps (not shown) on the bonding surfaces of each thermoelectric conversion element B and the thin L-shaped plate heat device 20, and an adhesive having a good thermal conductivity, such as heat conduction grease 21 or adhesion, is present in the gap. Apply and fill the agent. At this time, the thermoelectric conversion element B and the thin L-shaped plate heat device 20 are slid against each other so as not to seal bubbles in the heat conductive grease 21 filled in the gap and so that the thickness of the heat conductive grease 21 does not increase. Weld together. As the heat conductive grease 21, a silicone grease or the like kneaded with metal fine powder such as zinc oxide, or silver paint, which has a high heat conductivity and is effective as a coating agent for obtaining good heat conduction, is adopted.
In the present invention, the thin L-shaped plate heat device 20 is not limited to this shape, and may have various shapes such as a rectangular shape and a square shape depending on the installation location and design conditions of the power generation apparatus E according to the present invention. It doesn't matter.
Reference numeral 22 denotes a heat source that absorbs heat by installing the power generation device E according to the present invention. In FIG. 1, the power generation apparatus E and the heat source 22 according to the present invention are illustrated separately from each other, but in the embodiment, the heat source 22 is connected to the other side of the thin L-shaped plate heat device 20, that is, a metal flat plate ( The thin plate 15A and the flat thin plate 19 shown in FIGS. At that time, the heat conduction grease 21 and the like are interposed and adhered, and the heat source 22 and the thin L-shaped plate heat device 20 are thermally integrated.

Therefore, the working fluid 16a enclosed in the loop-shaped meandering narrow tunnel heat pipe 16 and the long meandering narrow groove 18a of the thin L-shaped plate heat device 20 ingests latent heat and evaporates. The steam is sent out from an evaporation section (not shown) through the loop-shaped meandering thin tunnel heat pipe 16 and the long meandering narrow groove 18a of the thin L-shaped plate heat device 20.
