Изобретение относитс к устройствам дл вентил ции транспортных средств, преимущественно автобусов.The invention relates to devices for the ventilation of vehicles, preferably buses.
Цель изобретени - снижение кинетической энергии приточной струи воздуха путем ее начальной турбулизации за счет движени отдельных струй воздуха навстречу друг другу и их соударени под определенными углами.The purpose of the invention is to reduce the kinetic energy of the supply air jet by its initial turbulence due to the movement of individual air jets towards each other and their impact at certain angles.
На чертеже изображено устройство дл вентил ции салона транспортного средства, продольное сечение.The drawing shows a device for ventilating a vehicle cabin, longitudinal section.
Устройство дл вентил ции кабины транспортного средства содержит воздухозаборник 1, на выходе из которого установлены две перфорированные пластины 2 и 3. В первой пластине 2 выполнены продольные отверсти 4 трапециевидной формы, причем большее основание трапеции расположено у входного отверсти воздухозаборника 1. Во второй пластине 3 выполнены продольные отверсти 5 пр моугольной формы. Отверсти 5 смещены относительно отверстий 4.The vehicle cabin ventilation device comprises an air intake 1, at the exit of which two perforated plates 2 and 3 are installed. The first plate 2 has longitudinal holes 4 of a trapezoidal shape, with a larger base of the trapezium located at the inlet of the air intake 1. The second plate 3 is made longitudinal holes 5 rectangular shapes. Holes 5 are offset relative to the holes 4.
Устройство дл вентил ции салона работает следующим образом.The device for ventilation of the cabin works as follows.
Поток приточного воздуха, войд в люк через приподн тую крышку воздухозаборника 1, делитс на отдельные струи благодар пластине 2, а за счет пластины 3 происходит их соударение, и, как следствие, эффективное гашение скоростей в направлении распространени приточного потока. Пр моугольной форме продольных отверстий 5 пластины 3 соответствует неравномерна раздача воздуха, а трапециевидной форме отверстий 4 пластины 2 - равномерна .The supply air flow entering the hatch through the raised air intake lid 1 is divided into separate jets due to the plate 2, and due to the plate 3 they collide and, as a result, effective damping of the velocities in the direction of the distribution of the inlet flow. The rectangular shape of the longitudinal holes 5 of the plate 3 corresponds to an uneven distribution of air, and the trapezoidal shape of the holes 4 of the plate 2 is uniform.
Устройство обеспечивает эффективное гащение кинематической энергии приточной струи и обладает сравнительно небольшим аэродинамическим сопротивлением (коэффициент местного сопротивлени 1,8-2,0). Использование предлагаемого устройства приводит к повышению эффективности работы вентил ции салонов транспортных средств, т.е. обеспечивает улучшение самочувстви пассажиров, уменьшает веро тность их заболеваемости .The device provides effective powering of the kinematic energy of the supply jet and has a relatively small aerodynamic drag (coefficient of local resistance of 1.8-2.0). The use of the proposed device leads to an increase in the efficiency of the operation of the ventilation of vehicle interiors, i.e. provides for improved well-being of passengers, reduces the likelihood of their incidence.
