Title:
THERMOELECTRIC ELEMENT-USED COOLING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/105145
Kind Code:
A1
Abstract:
A thermoelectric element-used cooling method suitable for cooling electronic members or the like, and a small cooling device using the cooling method, wherein when separated ends of an n-type semiconductor and a p-type semiconductor are respectively joined to the opposite ends of a Pt metal thin film, for example, as shown in Fig. 2(a) and Cu electrodes are respectively joined to the other ends of the n-type semiconductor and the p-type semiconductor to allow a current to flow in a direction from the n-type semiconductor to the p-type semiconductor, the n-type semiconductor-side components as a whole exhibit an endothermic action independently to effect cooling in the temperature distribution as shown. When a Cu metal thin film is used, components on both semiconductor sides cools similarly as shown in (b). When a Pb metal thin film is used, components on the p-type semiconductor are cooler than those on the the n-type semiconductor side. This action is effectively used to cool electronics elements such as semiconductor laser elements and to cool micro-scale reaction devices used for biological/chemical reactions or the like.
