Title:
COOLING AND POWER GENERATION DEVICE, AND COOLING AND POWER GENERATION SYSTEM USING SAID COOLING AND POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/138288
Kind Code:
A1
Abstract:
[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.
