HEAT DISSIPATION APPARATUS FOR OPTICAL MODULE AND COMMUNICATION DEVICE USING HEAT DISSIPATION APPARATUS Russian patent published in 2018 - IPC H05K7/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used to dissipate heat for an optical module. Device comprises a guide rail, wherein the guide rail is set on a circuit board for accommodating the optical module, the guide rail being covered with a heat conduction block, heat dissipation teeth are formed on a part of areas on the heat conduction block, the heat dissipation teeth are positioned at a rear portion of the guide rails, the heat dissipation teeth extend in a direction close to the circuit board, so that the heat dissipation teeth and the guide rails are positioned at the same side of the heat conduction block.

EFFECT: technical result consists in ensuring the efficiency of heat dissipation by the thermal conductivity of the heat conduction block and the dissipation of heat by heat dissipating teeth.
