FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular to industrial greenhouse industries, in which hydroponic technologies of growing various crops are used. In the proposed design of the solution cooler, a two-case layout of the apparatus is used, and thermal elements with an intermediate heat carrier are used as heat transfer elements. Internal apparatus has a square shape. External apparatus has the shape of a hexagon in plan view. Heat pipes are arranged in walls of internal apparatus. Warm nutrient solution is fed into the cavity of the internal apparatus through the holes in the upper cover. Heat-absorbing evaporation sections of heat pipes are placed in the cavity of the internal apparatus, and heat-removing – condenser sections are placed in the annular cavity.
EFFECT: intensification of heat exchange and reduction of overall dimensions and weight of the device.
