Modern electronic means (EM), including the onboard equipment, execute an increasing number of functions and their hardware technical solutions become more difficult. At the same time density of spatial placement of elements increases and density of heat dissipation by set of radio-electronic components (REC) in EM increases too. This worsens the thermal mode of the EM - first of all, because it exceeded the ratios of the actual heat load in comparison with maximum permissible norms. As a result operational reliability of EM reduced due to the following factors: the appearance of REC failures, leading to accidents; the reduction of the REC service life due to the earlier appearance of signs of load-carrying structures limit statuses. Therefore the developers of EM are faced by the urgent task to reduce the operation temperature of REРЎ. Cooling heat sinks - including in combination with fans (to enhance heat transfer from the heat sink to the air by forced convection) are usually used to this purpose. In terms of dense arrangement REC in EM and a high level of elements heat dissipation the optimal choice of heat sinks designs (including specially designed for a particular model or group of models of EM) can be a daunting task. This article describes the various types of heat sinks. The calculation method of heat sinks in case of their use as cooling devices is examined in the article. Authors are shown the necessity of the parameters identification participating in calculations of nodes of heat sinks. The authors analyzed the reasons of defects appearance in nodes of heat sinks. Also authors justified the necessity of diagnostics and the technique of diagnostic modeling of EM with heat sinks in case of their design is given. In the conclusions are made short summary on the problems of calculations and the diagnostic simulation of EРњ with cooling heat sinks.
