DEVICE FOR DRAINING HEAT FROM ELEMENTS OF RADIO-ELECTRONIC EQUIPMENT WITH REPEATED SHORT-TERM HEAT EXHAUSTS Russian patent published in 2005 - IPC

FIELD: radio-electronics.

SUBSTANCE: device has thin-walled metallic container, filled with working agent, on one of end surfaces of which radio-electronic equipment element is placed. Metallic container has shape of rectangular parallelepiped, on two opposite sides of lesser area of which in upper and lower portions shelves are present. Thickness of shelves matches thickness of metallic container, and height and length of shelves are equal respectively to 1/4 of its height and length. Recesses in conjunction with cover, made of highly heat-conductive material and held on metallic container on edges of shelves, form an air duct. Air duct has shape of pipe of rectangular cross-section with height, appropriate for height of recesses, and circling three sides of metallic container (one side of greater area and two sides of lesser area), at input and output of which ventilators are mounted, powered by electric energy source. One of ventilators works to force air flow into air duct, and other one - to force air out of air duct.

EFFECT: no limits on pause duration during operation of radio-electronic equipment.
