Description
(54) ТЕПЛООБМЕННАЯ ПОВЕРХНОСТЬ(54) HEAT EXCHANGE SURFACE
Изобретение относитс к теплообменной аппаратуре и может быть использовано в знергетической промышленности .The invention relates to heat exchange equipment and can be used in the energy industry.
Известны теплообменные поверхности дл систем кондиционировани воз духа, содержащие расположенные параллельными р дами трубы с поперечным пластинчатым оребрением, выполненным в виде желобов, смещенных в смежных р дах на полшага и обращенЦых выпуклостью в разные стороны tl.Heat transfer surfaces are known for air-conditioning systems that contain pipes arranged in parallel rows with transverse plate fins made in the form of grooves displaced in adjacent rows by half a step and facing convexity in different directions tl.
Недостатком известной поверхности вл етс низкий коэффициент теплоотда и к теплоносителю, протекающему в межтрубном.пространстве.A disadvantage of the known surface is the low coefficient of heat transfer to the coolant flowing in the annular space.
Цель изобретени - интенсификаци теплообмена.The purpose of the invention is to intensify heat transfer.
Указанна цель достигаетс тем, что трубы имеют вогнутый профиль с радиусом кривизны, составл ющим 0,65-0,9 длины их дуги, и в смежных р дах обращены вогнутост ми в противоположные стороны.This goal is achieved by the fact that the pipes have a concave profile with a radius of curvature of 0.65-0.9 times the length of their arc, and in adjacent rows are turned towards the opposite sides by concavities.
На чертеже схематично изображена, предлагаема теплообменна поверхность . The drawing schematically shows the proposed heat exchange surface.
Теплообменна поверхность содержит расположенные параллельными р дами 1 и 2 трубы 3 с поперечнымThe heat exchange surface contains pipes 3 arranged in parallel rows 1 and 2 with transverse
пластинчатым оребрением 4, выполненным в виде желобов, смещенных в смежных р дах 1 и 2 на полшага и обра|щенных вогнутостью в разные стороны. Трубы 3 имеют вогнутый профиль с радиусом кривизны, составл ющим 0,65-0,9 длины их дуги, и в смежных р дах 1 и 2 обращены вогнутост ми в противоположные стороны. Желоба вы10 полнены с радиусом кривизны,, составл ющим 0,6-0,7 длины их дуги.lamellar fins 4, made in the form of grooves, displaced in adjacent rows 1 and 2 by half a step and inverted in opposite directions. The pipes 3 have a concave profile with a radius of curvature of 0.65-0.9 times the length of their arc, and in adjacent rows 1 and 2 are turned in opposite directions by concavities. The gutters are filled with a radius of curvature that is 0.6-0.7 in the length of their arc.
Теплоноситель циркулирует по трубам 3 и отдает тепло потоку воздуха,The coolant circulates through the pipes 3 and gives off heat to the air flow,
15 который в поперечном направлении омывает теплообменную поверхность, проход по каналам, образованным вогнутой поверхностью трубок 3 и пластинчатого оребрени 4. За счет15 which in the transverse direction washes the heat exchange surface, the passage through the channels formed by the concave surface of the tubes 3 and the plate fins 4. Due to
20-вогнутости труб 3 и оребрени 4, в каналах дл воздуха создаютс вихревые течени , повышающие коэффициент теплоотдачи к воздуху.20-concavity of the tubes 3 and the fins 4, eddy currents are created in the air channels, increasing the heat transfer coefficient to the air.
Выполнение труб с радиусом кривгиз25 ны 0,65-0,9 от длины их дуг и ориентирование их в смежных р дах вогнутост ми в противоположные стороны увеличивает коэффициент теплоотдачи и интенсифицирует теплообмен The making of pipes with a radius of curvature of 0.65-0.9 from the length of their arcs and their orientation in adjacent rows with concavities in opposite directions increases the heat transfer coefficient and intensifies the heat exchange
30 в целом.30 overall.
