Mathematical modeling of the heat exchange unit main parameters for photoenergy system based on general models with forced circulation of heat transfer fluid. Methodology. To determine the coefficient of heat transfer at a given coolant temperature and surfaces temperature necessary to determine the temperature gradient in the wall of the heat exchanger.

У роботі розглядаються особливості підбору теоретичного підґрунтя та математичне моделювання теплових процесів у теплообмінному блоці для комбінованої фотоенергетичної установки. За результатами моделювання проведено вдосконалення та розробку високоефективного теплообмінного блоку з мікроканалами. Апробація запропонованого блоку підтвердила його високу ефективність за рахунок реалізації турбулентного режиму протікання теплоносія. Використання такого теплообмінника дозволить підвищити якість і рівномірність охолодження сонячних батарей та зменшити витрати енергії на циркуляцію рідини.
