Description

(54) ГОФРИРОВАННАЯ ВСТАВКА ДЛЯ ПЛАСТИНЧАТОГО ТЕПЛООВМЕННИКА(54) CORRUGATED INSERT FOR PLASTIC HEAT EXCHANGER

налом должна подводитс  к потоку теплоносител , в узком пристенном слое с тем, чтобы она затрачивалась только на его турбулизацию . Именно в этом слое сосредоточено наибольшее термическое сопротивление тепловому потоку в канале.The water should be supplied to the coolant flow in a narrow wall layer so that it is spent only on its turbulization. It is in this layer that the greatest thermal resistance to heat flow in the channel is concentrated.

Профиль канала гофров выполн етс  таким образом, чтобы степень дросселировани  потока теплоносител  характеризовалась отношением гидравлического диаметра d в самом узком сечении канала к гидравлическому диаметру d гладкого участка канала, равным d/d 0,65-0,92. Действительно, масштаб вихревых масс, образуемых за узким сечением канала, а также их место расположени  в пристенном слое определ ютс  отношением d/d 0,65-0,92.The channel profile of the corrugations is designed so that the degree of throttling of the coolant flow is characterized by the ratio of the hydraulic diameter d in the narrowest section of the channel to the hydraulic diameter d of the smooth channel section equal to d / d 0.65-0.92. Indeed, the scale of the vortex masses formed beyond the narrow section of the channel, as well as their location in the near-wall layer, is determined by the ratio d / d 0.65-0.92.

Отношение высоты h канала (гофра) к шагу t ребер (гофров) в гофрированной вставке составл ет h/t 4-6. Значени  диапазона изменени  этого соотношени  обеспечивают благ гопри тные физические услови  образовани  и распространени  в пристенном слое канала турбулентных вихрей за узким его сечением, особенно в угловых зонах 6, так как в канал оделевидного сечени  в угловых зонах по вл ютс  вторичные токи: Эти токи способствуют более ранней турбулизаЦйи течени  в углах. На фоне этого турбулизиро/ 2The ratio of the height h of the channel (corrugation) to the pitch t of the ribs (corrugations) in the corrugated insert is h / t 4-6. The values of the range of variation of this ratio provide favorable physical conditions for the formation and propagation of turbulent vortices in the near-wall layer of the channel beyond its narrow cross section, especially in the corner zones 6, since secondary currents appear in the channel of a clear section in the corner zones: early turbulant currents in the corners. Against the background of this turbulence / 2

ванного течени  в углах образование и развитие турбулентных вихрей за узким сечением канала происходит незатрудненно. В результате сокраш.аютс  энергозатраты на одинаковую интенсификацию теплообмена.At the corners of the flow, the formation and development of turbulent eddies behind a narrow channel section occurs without difficulty. As a result, energy consumption for the same intensification of heat exchange is reduced.
