Description
本揭露是有關於一種熱電轉換裝置以及熱電轉換器,且特別是有關於一種具有可與流體直接接觸的突出電極的熱電轉換裝置以及熱電轉換器。The present disclosure relates to a thermoelectric conversion device and a thermoelectric converter, and more particularly to a thermoelectric conversion device having a protruding electrode that can be in direct contact with a fluid, and a thermoelectric converter.
由於能源短缺問題,再生能源技術的發展成為了重要議題。熱電轉換技術為目前一種可直接將熱能與電能進行轉換的新興再生能源技術,此熱電轉換效應是藉由熱電材料內部載子移動讓熱能與電能達到能量轉換之功效。近年來,熱電轉換技術受到各國相關研究單位高度重視並投入大量研發能量,除了材料的開發,也積極進行熱電技術應用。The development of renewable energy technologies has become an important issue due to energy shortages. The thermoelectric conversion technology is an emerging renewable energy technology that can directly convert thermal energy and electrical energy. The thermoelectric conversion effect is to convert energy between thermal energy and electrical energy by the internal carrier movement of the thermoelectric material. In recent years, thermoelectric conversion technology has been highly valued by relevant research units in various countries and has invested a large amount of research and development energy. In addition to the development of materials, it is also actively applying thermoelectric technology.
熱電模組(thermoelectric module)是熱電轉換技術的應用產品之一。具體地說,熱電模組為一種具有熱與電兩種能量互相轉換特性之元件。對熱電模組通入直流電時,熱電模組兩端產生溫差,由冷端吸熱將熱能送到熱端放出,達到熱泵(heat pump)的功能,此為珀爾帖效應(Peltier effect)。另一方面,若熱電模組兩端處於不同溫度時,熱電模組即產生直流電,溫差越大的時候,產生的電功率越高,此為塞貝克效應(Seebeck effect)。The thermoelectric module is one of the applications of thermoelectric conversion technology. Specifically, the thermoelectric module is an element having a mutual conversion characteristic between heat and electricity. When the thermoelectric module is connected to the direct current, a temperature difference is generated at both ends of the thermoelectric module, and the heat is transferred from the cold end to the hot end to reach the heat pump function, which is the Peltier effect. On the other hand, if the two ends of the thermoelectric module are at different temperatures, the thermoelectric module generates direct current. When the temperature difference is larger, the electric power generated is higher, which is the Seebeck effect.

As can be seen from Fig. 8, the water temperature before the test was about 28 ° C, the temperature of the water at the heating end was increased to 36 ° C after the application of electric power to the test device, and the water temperature at the cold end was lowered to 27 ° C. Therefore, as is apparent from the results of FIGS. 7 and 8 described above, the thermoelectric conversion device of the present invention does have the heat pump function of the thermoelectric element regardless of whether it is in the air or in a water-passing state. <Test of the influence of joint area>
提供長條狀的P型熱電材料以及N型熱電材料,其中P型熱電材料以及N型熱電材料的尺寸為40mm(L)×5mm(W)×2mm(T)。接著,使用作為電極的銅箔對P型熱電材料以及N型熱電材料的由40mm(L)×5mm(W)構成的兩側面進行焊接,以構成N-P-N的結構。其中對於電極與P型熱電材料以及N型熱電材料接合的面積分別設定如下:5mm(W)×3mm(L)、5mm(W)×6mm(L)以及5mm(W)×10mm(L)。A long P-type thermoelectric material and an N-type thermoelectric material are provided, wherein the size of the P-type thermoelectric material and the N-type thermoelectric material is 40 mm (L) × 5 mm (W) × 2 mm (T). Next, the two side faces of the P-type thermoelectric material and the N-type thermoelectric material, which are composed of 40 mm (L) × 5 mm (W), were welded using a copper foil as an electrode to constitute a structure of N-P-N. The areas where the electrodes are bonded to the P-type thermoelectric material and the N-type thermoelectric material are set as follows: 5 mm (W) × 3 mm (L), 5 mm (W) × 6 mm (L), and 5 mm (W) × 10 mm (L).
接著,對於前述3種不同面積的熱電轉換裝置通入不同功率的直流電進行測試,量測接合電極的溫差,其結果如圖9所示。由圖9可知,在相同的熱電材料條件之下,藉由提高電極與熱電材料的接合面積,能夠增加致冷端的電極與加熱端的電極的的溫差,從而達到提高熱電熱泵的功效。Next, the above three different types of thermoelectric conversion devices are tested by passing direct current of different powers, and the temperature difference of the bonding electrodes is measured, and the result is shown in FIG. It can be seen from FIG. 9 that under the same thermoelectric material condition, by increasing the bonding area of the electrode and the thermoelectric material, the temperature difference between the electrode at the cold end and the electrode at the heating end can be increased, thereby improving the efficiency of the thermoelectric heat pump.
綜上所述,本揭露的熱電轉換裝置或熱電轉換器中的第一電極以及第二電極接合於P型熱電材料以及N型熱電材料的兩側面,因此能夠具有更大的接合面積,從而能夠更為提升熱電轉換以及熱能輸送的效果。另一方面,即使是將熱電材料小型化或者是薄型化,藉由本揭露的上述構成,也能夠確保充足的接合面積,從而能夠得到良好的熱電轉換以及熱能輸送的效果。In summary, the first electrode and the second electrode in the thermoelectric conversion device or the thermoelectric converter of the present disclosure are bonded to both sides of the P-type thermoelectric material and the N-type thermoelectric material, and thus can have a larger bonding area, thereby enabling It also enhances the effects of thermoelectric conversion and heat transfer. On the other hand, even if the thermoelectric material is miniaturized or thinned, the above-described configuration of the present invention can ensure a sufficient bonding area, and an excellent thermoelectric conversion and heat energy transfer effect can be obtained.
此外,本揭露的熱電轉換裝置或熱電轉換器中的第一電極以及第二電極突出於P型熱電材料以及N型熱電材料的端部(絕緣絕熱材料或是外殼)之外,本揭露的熱電轉換裝置或熱電轉換器在後續使用時,能夠使流體直接流經第一電極以及第二電極以進行熱交換,熱電材料與金屬電極的接合處所產生之熱電轉換效應可不需透過絕緣基板熱傳導進行應用,因此可不受限於絕緣基板本身的熱阻降低了實際可應用的性能。此外,亦不需在絕緣基板的外側進行熱交換,可減少熱電模組的熱電轉換效率再次受到損耗,從而能夠提升熱交換的效能。In addition, the first electrode and the second electrode in the thermoelectric conversion device or the thermoelectric converter of the present disclosure protrude beyond the end of the P-type thermoelectric material and the N-type thermoelectric material (insulating insulating material or outer casing), and the disclosed thermoelectricity The conversion device or the thermoelectric converter can directly flow the fluid through the first electrode and the second electrode for heat exchange, and the thermoelectric conversion effect generated by the junction of the thermoelectric material and the metal electrode can be applied without heat conduction through the insulating substrate. Therefore, the thermal resistance of the insulating substrate itself can be reduced without being practically applicable. In addition, heat exchange on the outside of the insulating substrate is not required, and the thermoelectric conversion efficiency of the thermoelectric module can be reduced again, thereby improving the efficiency of heat exchange.
而且,在本揭露的熱電轉換裝置或熱電轉換器中,藉由使第一電極以及第二電極分別為兩片的U型片狀電極,與習知架構相較之下,本揭露的第一電極以及第二電極能夠得到約兩倍以上的熱交換面積,因此能夠更為增加第一電極以及第二電極與流體的熱交換效能。Moreover, in the thermoelectric conversion device or the thermoelectric converter of the present disclosure, the first electrode and the second electrode are respectively two U-shaped sheet electrodes, and the first of the disclosure is compared with the conventional architecture. The electrode and the second electrode are capable of obtaining about twice or more of the heat exchange area, and thus the heat exchange efficiency of the first electrode and the second electrode with the fluid can be further increased.
綜合上述所揭示的各優點,本揭露的熱電轉換裝置或熱電轉換器即使是將熱電材料小型化或是薄型化的情況下,仍然能夠具有優良的熱電轉換以及熱能輸送的效果,因此,本揭露能夠提供小型化(或是薄型化)且具有高效能的熱電轉換裝置或熱電轉換器。In view of the advantages disclosed above, the thermoelectric conversion device or the thermoelectric converter of the present invention can have excellent thermoelectric conversion and thermal energy transfer effects even when the thermoelectric material is miniaturized or thinned. It is capable of providing miniaturization (or thinning) and high-performance thermoelectric conversion devices or thermoelectric converters.
