参照图3所示,在本发明的另一个实施例,还包括热传导装置15,所述热传导装置15贴设于所述制冷设备20的散热面,所述热电转换器10的热端贴设于所述热传导装置15。如图6示例中,热传导装置15贴设于制冷设备20的背面,热电转换器10的热端贴设在热传导装置15上。Referring to FIG. 3, in another embodiment of the present invention, a heat transfer device 15 is further disposed, the heat transfer device 15 is attached to a heat dissipation surface of the refrigeration device 20, and the hot end of the thermoelectric converter 10 is attached to The heat transfer device 15. In the example of FIG. 6, the heat transfer device 15 is attached to the back surface of the refrigeration unit 20, and the hot end of the thermoelectric converter 10 is attached to the heat transfer device 15.
由于热传导装置15具有良好的热传导性能,所以,制冷设备20的热量通过热传导装置15可以快速传导至热电转换器10的热端,进而确保热电转换器10的热端具有较高的温度。由此,可以提高热电转换器10的热端和冷端之间温差,温差越大则产生的电能越大,即转换形成的第一直流电的电压越高。也即是,提高了热电转换器10的转换效率。Since the heat conduction device 15 has good heat conduction performance, the heat of the refrigeration device 20 can be quickly conducted to the hot end of the thermoelectric converter 10 through the heat conduction device 15, thereby ensuring that the hot end of the thermoelectric converter 10 has a higher temperature. Thereby, the temperature difference between the hot end and the cold end of the thermoelectric converter 10 can be increased, and the greater the temperature difference, the greater the electric energy generated, that is, the higher the voltage of the first direct current formed by the conversion. That is, the conversion efficiency of the thermoelectric converter 10 is improved.
参照图7所示,在本发明的一个具体实施例中,热传导装置15包括第一中空导热板151、第二中空导热板152、第三中空导热板153及变相介质。Referring to FIG. 7, in one embodiment of the present invention, the heat transfer device 15 includes a first hollow heat conducting plate 151, a second hollow heat conducting plate 152, a third hollow heat conducting plate 153, and a phase change medium.
具体的,第一中空导热板151水平布置,所述热电转换器10的热端贴设于所述第一中空导热板151。第二中空导热板152竖向布置且贴设于所述制冷设备20的散热面。Specifically, the first hollow heat conducting plate 151 is horizontally disposed, and the hot end of the thermoelectric converter 10 is attached to the first hollow heat conducting plate 151. The second hollow heat conducting plate 152 is vertically disposed and attached to the heat dissipating surface of the refrigeration device 20 .
复数个第三中空导热板153倾斜布置于所述第一中空导热板151和第二中空导热板152之间,且每个所述第三中空导热板153的上端与所述第一中空导热板151相连通,每个所述第三中空导热板153的下端与所述第二中空导热板152相连通,以使所述第一、第二和第三中空导热板151、152、153之间形成介质回路。如图1所示,第三中空导热板153与第 一中空导热板151和第二中空导热板152形成三角形结构。A plurality of third hollow heat conducting plates 153 are obliquely disposed between the first hollow heat conducting plate 151 and the second hollow heat conducting plate 152, and an upper end of each of the third hollow heat conducting plates 153 and the first hollow heat conducting plate 151 is connected to each other, and a lower end of each of the third hollow heat conducting plates 153 is in communication with the second hollow heat conducting plate 152 to connect the first, second and third hollow heat conducting plates 151, 152, 153 Form a dielectric loop. As shown in FIG. 1, the third hollow heat conducting plate 153 and the first A hollow heat conducting plate 151 and a second hollow heat conducting plate 152 form a triangular structure.
变相介质填充在所述介质回路中,且被构造成当温度大于预定值时,所述变相介质由液态变为汽态。A phase change medium is filled in the medium circuit and configured to change from a liquid state to a vapor state when the temperature is greater than a predetermined value.
具体工作过程中,第二中空导热板152吸收制冷设备20的热量,其内部的变相介质吸热气化为汽态,汽态的变相介质经由复数个第三中空导热板153上升至第一中空导热板151内(图中箭头所示方向),高温度的汽态变相介质将热量传递给第一中空导热板151,第一中空导热板151再将温度快速传导至热电转换器10的热端,由此,第一中空导热板151与热电转换器10进行热交换后,其温度降低,此时,由于第一中空导热板151的温度降低,其汽态的变相介质重新凝结变成液态,并在重力作用下自由下落,经由复数个第三中空导热板153下落至第二中空导热板152内,如此循环,可以实现快速将热量传导至热电转换器10的热端,使得热电转换器10热端的热能聚集,达到更高的温度,进而使得热电转换器10热端与冷端形成更大的温差,最终,提高其热电转换器10的转换效率。During the specific working process, the second hollow heat conducting plate 152 absorbs the heat of the refrigeration device 20, and the internal phase change medium absorbs heat into a vapor state, and the vapor phase change medium rises to the first hollow through the plurality of third hollow heat conducting plates 153. In the heat conducting plate 151 (in the direction indicated by the arrow in the figure), the high temperature vapor phase change medium transfers heat to the first hollow heat conducting plate 151, and the first hollow heat conducting plate 151 quickly conducts the temperature to the hot end of the thermoelectric converter 10 Therefore, after the first hollow heat conducting plate 151 exchanges heat with the thermoelectric converter 10, the temperature thereof is lowered. At this time, since the temperature of the first hollow heat conducting plate 151 is lowered, the vapor phase variable medium is recondensed into a liquid state. And falling freely under the action of gravity, falling into the second hollow heat conducting plate 152 via the plurality of third hollow heat conducting plates 153, and circulating, the heat can be quickly transferred to the hot end of the thermoelectric converter 10, so that the thermoelectric converter 10 The thermal energy at the hot end is concentrated to reach a higher temperature, thereby causing a larger temperature difference between the hot end and the cold end of the thermoelectric converter 10, and finally, the conversion efficiency of the thermoelectric converter 10 is improved.

作为优选地,散热片154为波浪形,波浪形的散热片154可以增大导热面积,进而使得第三中空导热板153之间的热传导更加均匀、更加迅速。Preferably, the fins 154 are undulating, and the undulating fins 154 may increase the heat transfer area, thereby making the heat conduction between the third hollow heat conducting plates 153 more uniform and faster.
