Цель. В статье рассматривается термоэлектрический теплообменник –интенсификатор теплопередачи, предназначенный для обеспечения теплового режима элек-тронного оборудования, размещенного во внешних установках.</p></sec><sec><title>Метод</title><p>Метод. Применены методы моделирования теплообменных процессов.</p></sec><sec><title>Результат</title><p>Результат. Предлагается термоэлектрическая система, представляющая собой теплообменник – интенсификатор теплопередачи, который размещен во внешней установке. Конструктивно внешняя установка содержит первый отсек с электронными тепловыделяющими компонентами, в котором предусмотрены проходы или каналы для продува внешнего воздуха и второй отсек, содержащий элементы с необходимостью герметизации от внешних воздействий и недопустим контакт с внешним охлаждающим воздухом. Приведена математическая модель, которая позволяет определить температуру потоков воздуха по теплообменным поверхностям термоэлектрической системы (ТЭС), а также предельную длину термоэлектрической системы для достижения равенства температур потоков на выходе при заданных токах питания термоэлектрических батарей.</p></sec><sec><title>Вывод</title><p>Вывод. Проведенные исследования позволяют сделать вывод, что большей длине термоэлектрической системы для обеспечения режима интенсификации соответствует большая разница температур теплоносителей на входе. Очевидно, что при дальнейшем увеличении длины термоэлектрический теплообменник переходит в режим работы термоэлектрической холодильной машины, и температура потока воздуха на выходе становится ниже.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Abstract</title><p>Abstract. Aim. The article presents a thermoelectric heat exchanger / heat transfer intensifier design for ensuring the thermal regime of electronic equipment located in external installations.</p></sec><sec><title>Method</title><p>Method. Methods for modelling heat exchange processes were applied.</p></sec><sec><title>Result</title><p>Result. A thermoelectric system is proposed, consisting of a heat exchanger / heat transfer intensifier component located in an external installation. In structural terms, the external installation comprises a compartment disposing electronic heatgenerating components, in which are located channels for ventilating external air, while a second compartment contains elements that require to be sealed from external influences, in cluding contact with external cooling air. A mathematical model is provided for determining the temperature of air flows from the heatexchange surfaces of a thermoelectric system (TES), as well as the limiting length of a thermoelectric system to achieve equal output temperature at given supply currents of thermoelectric batteries.</p></sec><sec><title>Conclusion</title><p>Conclusion. On the basis of the conducted studies, it is concluded that a longer thermoelectric system for ensuring the intensification mode corresponds to an increased difference in the temperature of the coolant at the inlet. The temperature of the air flow at the outlet becomes lower with a further increase in length due to the thermoelectric heat exchanger entering the operating mode of the thermoelectric refrigeration unit.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>термоэлектрическая система</kwd><kwd>система обеспечения теплового режи-ма</kwd><kwd>термоэлектрический теплообменник</kwd><kwd>математическая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thermoelectric system</kwd><kwd>thermal regime control system</kwd><kwd>thermoelectric heat exchanger</kwd><kwd>mathematical model</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Исмаилов Т.А., Гаджиев Х.М.
