RADIATOR AND RADIATIVE COOLER USING SUCH RADIATOR Russian patent published in 2005 - IPC

FIELD: radiators and radiative coolers using such radiators.

SUBSTANCE: proposed radiator is built of plurality of radiator fins and separate fins are joined together to ensure their development in radial direction thereby enlarging its surface area and increasing its heat-transfer efficiency. Radiator is installed within radiative cooler in air conduit, and fan feeds cold air to this air conduit thereby additionally raising heat-transfer efficiency. Radiator force of coupling with heat source can be elastically maintained which makes it possible to maintain its coupling with heat source even upon external impacts. In addition cutting out upper part of fin enables shortening of fold line so that heat-absorbing parts of radiator fins piled one on top of other can be tightly joined during radiator formation at lower force applied. Radiator obtained has depression in center of upper surface. Such mechanical design makes it possible for fan-forced cold air to reach radiator bottom center thereby additionally raising heat-transfer efficiency. In addition, noise and vibrations caused by cold air flow over heat-transfer parts of radiator are reduced.

EFFECT: facilitated manufacture and improved characteristics of radiator.
