COOLING DEVICE FOR ELECTRONIC BOARDS Russian patent published in 2011 - IPC H05K7/20 

FIELD: electricity.

SUBSTANCE: it is proposed to use single-cascade thermoelectric batteries (TEB) arranged in installation places of components of communications-electronics equipment, which are the most critical to temperature mode of operation or require essential temperature decrease. TEB shall be installed in cavities on surface of metal capacity filled with working medium having high fusion heat value and fusion temperature within 35÷65°C, which contacts the rest part of electronic board. At that, in capacity with working medium there provided are hollow holes located in line order, through which air is pumped by means of fans.

EFFECT: simplifying the design and manufacturing procedure of the device, as well as possibility of coordination of operating modes of thermoelectric batteries.
