HEAT SINK AND COMPOUND TYPE SOLAR ENERGY CONVERSION DEVICE

摘要

PROBLEM TO BE SOLVED: To improve heat radiation effect under natural convection conditions in a heat sink used in a compound type solar energy conversion device.SOLUTION: A heat sink 1 includes: a base plate 2 connected with a peltier element provided on a rear surface of a solar cell panel; a column 3 erected on the base plate 2; and multiple plate-like fins 4 which are provided arranged in an extension direction of the column 3 relative to the column 3. Areas of the fins 4 decrease toward a tip 3b of the column 3 when viewed in the extension direction of the column 3.
