The main objective of the study was to regulate the thermal regime and ensure the reliability of electronic equipment Methods In order to conduct experimental studies of the thermoelectric cooling system using heat pipes, a stand was assembled on which the developed and manufactured prototype was studied. The object of the experimental studies was a prototype cooling system, consisting of a thermoelectric battery made of conventional unified thermoelectric materials of ICE-71 type. The solution of the research problems carried out by the method of reduction to ordinary differential equations (Kantorovich method) provides acceptable accuracy for such a class of problems. Results A design of a telecommunication equipment cabinet with a thermal management system based on the use of heat pipes and thermoelectric cooling units is proposed. A mathematical model for the determination of the thermal field in the cabinet volume is considered; an experimental stand for the prototype study is described; the results of experimental studies for various power sources of heat release are presented. Conclusion Experimental studies confirm the operability of the developed cooling system for cabinets with telecommunication equipment; this cooling method has advantages over conventional forced or natural cooling; the temperature in the block volume and the peak values of the heat sources are significantly reduced; at dissipation powers on one board within 50 W there is no need to use special means to remove heat from hot junctions of the thermoelectric battery
Вестник Дагестанского государственного технического университета. Технические науки. №4 (35), 2014 75 напряжений свыше 710 8 Н/м 2 , что более чем в 2 раза превышает величину пре-дела прочности меди, для термоэлектрического материала соотношение меха-нических нагрузок и предела прочности в данном случае еще выше.При этом, в соответствии с проведенными расчетами установлено, что для данной конструкции ТЭ наибольшим током питания без превышения допусти-мого значения механических нагрузок в системе является электрический ток, не превышающий величины 82 А, т.е. почти в 1,7 раза меньше, чем в случае ис-пользования слоистого ТЭ, для которого максимальная величина тока питания по расчетам составляет 140 А.Таким образом, проведенные расчеты в полной мере подтверждают пре-имущества слоистой ТЭБ перед ТЭБ, выполненной из ТЭ П-образной формы. В первом случае можно получить более мощную ТЭБ без снижения ее термо-механических характеристик и надежности работы.
