Abstract

Изобретение м.б. использовано в автомобильных кондиционерах. Цель изобретени - интенсификаци теплообмена при подаче хладагента в трубное пространство. Корпус 2 разделен горизонтальными перегородками 3 на сообщающиес секции 4, В секци х 4 размещены теплообменные трубы, выполненные в виде плоских змеевиков 6 с уменьшающимс живым сечением в направлении оси трубы от входа хладагента к выходу, при соотношении входного и выходного сечений трубы в диапазоне 1,6-1,15, Сечение трубы вьтолнено в виде овала, больша ось которого размещена в вертикальной плоскости. Дл облегчени механической очистки наружной поверхности труб конденсатора корпус 2 выполнен разьемным. Дл уменьшени габаритов смежные трубы плоских змеевиков 6 расположены под углом одна к другой. Конструкци конденсатора позвол ет уменьшить поверхность, занимаемую жидкой фазой, и поддержать оптимальную скорость движени конденсируемой и охлаждающей сред. 2 з.п. ф-лы, 3 ил. (ЛInvention m. used in car air conditioners. The purpose of the invention is to intensify heat transfer when the refrigerant is supplied to the tube space. The housing 2 is divided by horizontal partitions 3 into communicating sections 4. In sections 4 heat exchange tubes are placed, made in the form of flat coils 6 with decreasing living section in the direction of the pipe axis from the refrigerant inlet to the outlet, with a ratio of 1 in 6-1.15. The section of the pipe is made in the form of an oval, the major axis of which is located in a vertical plane. To facilitate the mechanical cleaning of the outer surface of the condenser tubes, the housing 2 is detachable. To reduce the size, adjacent pipes of flat coils 6 are angled to one another. The design of the condenser reduces the surface occupied by the liquid phase and maintains the optimum speed of movement of the condensable and cooling media. 2 hp f-ly, 3 ill. (L
