Abstract
(EN)
[Problem] To provide a cooling and power generation device, the thermoelectric conversion efficiency of which is enhanced, the power generation ability of which is improved, and which can be used as a cooling device and also provide a cooling and power generation system using the cooling and power generation device. [Solution] The cooling and power generation device is provided with: a metal heat absorbing body 2 which has a touch surface touched to an object 9 to be cooled and to which the heat of the object to be cooled is transmitted via the touch surface; thermoelectric conversion elements 3A, 3B, the p-type and n-type of which are alternately projected side by side at intervals in a plural number on the outer surface of the heat absorbing body 2 and which have a plurality of through-holes 30 opening on the respective facing surfaces; electrode materials 41, 42 for electrically connecting the adjacent thermoelectric conversion elements to each other; and a flow path 5 for flowing a cooling fluid through the through-holes 30 of each of the thermoelectric conversion elements 3A, 3B. The cooling and power generation device yields a temperature gradient by cooling, by the cooling fluid, the thermoelectric conversion elements 3A, 3B to which heat is transmitted from the heat absorbing body 2 and functions as a cooler at the same time as generating power.

Le problème décrit par la présente invention est de fournir un dispositif de refroidissement et de production d'énergie dont l'efficacité de conversion thermoélectrique est améliorée, dont la capacité de production d'énergie est améliorée, et qui peut être utilisé comme dispositif de refroidissement et fournir également un système de refroidissement et de production d'énergie utilisant le dispositif de refroidissement et de production d'énergie. La solution selon l'invention porte sur un dispositif de refroidissement et de production d'énergie qui est pourvu : d'un corps d'absorption de chaleur métallique 2 qui a une surface tactile touchant un objet 9 à refroidir et auquel la chaleur de l'objet à refroidir est transmise par l'intermédiaire de la surface tactile ; d'éléments de conversion thermoélectrique 3A, 3B, le type p et le type n sont alternativement projetés côte à côte à des intervalles dans un nombre pluriel sur la surface extérieure du corps d'absorption de chaleur 2 et qui ont une pluralité de trous traversants 30 s'ouvrant sur les surfaces opposées respectives ; de matériaux d'électrode 41, 42 pour connecter électriquement les éléments de conversion thermoélectrique adjacents les uns aux autres ; et d'un trajet d'écoulement 5 pour faire circuler un fluide de refroidissement à travers les trous traversants 30 de chacun des éléments de conversion thermoélectrique 3A, 3B. Le dispositif de refroidissement et de production d'énergie produit un gradient de température en refroidissant, grâce au fluide de refroidissement, les éléments de conversion thermoélectrique 3A, 3B auxquels de la chaleur est transmise depuis le corps d'absorption de chaleur 2 et fonctionne comme un refroidisseur tout en produisant de l'énergie.
