DEVICE FOR COOLING ELECTRONIC BOARDS Russian patent published in 2009 - IPC H05K7/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electronics and can be used to provide required thermal conditions for components of communications electronics equipment, particularly electronic boards. Use of single-cascade thermoelectric batteries is proposed, placed where components of communications electronics equipment are installed, which are more critical to the operating temperature condition or which require significant decrease in temperature. Thermoelectric batteries are placed in depressions on the surface of a metal container, filled with working substance which has fusion heat and melting temperature in the range 35-65°C, in contact with the remaining part of the electronic board.

EFFECT: simple design and technology of making the device, as well as possibility of coordinating operating modes of thermoelectric batteries.
