agriculture, specifically, bee-keeping. SUBSTANCE: device controlling temperature condition in bee hive includes hive frames where first plate with reinforcing cells and heating element, temperature control with temperature-sensitive and temperature setting elements are installed. Second plate with reinforcing cells whose protrusions match bosses of cells on first plate is welded around contour with formation of combined reinforcing plate. In this case heating element is built on first plate in the form of resistive film uniformly sputtered over entire plane. Current-conducting low- resistance films are sputtered on edges of first plate over its whole width to which current-carrying contacts to supply power to heating element are connected by contact method. Temperature-sensitive element is electrically insulated from resistive film and resistive film, current-conducting low-resistance films, temperature-sensitive element and current-carrying contacts are located between first and second plates with current- conducting bus being mounted in hive body at points of suspension of frames. EFFECT: increased uniformity of heating and simplified structure of bee hive. 1 cl, 7 dwg
