A fin structure 16 for heat-exchanging, the fin structure 16 being mounted on a heat-dissipating portion 15 of a Stirling cycle cooler 7, wherein the fin structure 16 is configured by coupling a plurality of unit structures 16a, 16b, the plurality of unit structures 16a, 16b being split by a plurality of surfaces extending from a inner circumference of the fin structure 16 toward an outer circumference thereof. The fin structure 16 is configured thus way, whereby it can be mounted on the heat-dissipating portion 15 so as to sandwich the heat-dissipating portion 15 from the outer circumference thereof by the plurality of unit structures 16a, 16b coupled with each other. Accordingly, when mounting the fin structure 16, large force is not required, no adhesive filler is applied to an unneeded portion of the Stirling cycle cooler 7, and generating a scratch or a distortion on the casing of the Stirling cycle cooler 7 can be prevented. |
