Abstract

Изобретение позвол ет интенсифицировать теплообмен между средами. Теплообменник содержит корпус 1 с размещенным внутри пучком теплообменных труб 2 с винтовым оребрением, закрепленных в трубных досках, и расположенные в межтрубном пространстве поперечные сегментные перегородки 4 с отверсти ми под трубы 2. Перегородки 4 выполнены тонкостенными. Каждое отверстие в перегородках 4 имеет диаметр, меньший наружного диаметра оребрени . В зоне каждого отверсти перегородки имеют радиальную рассечку относительно оси отверсти , кромки которой отогнуты в противоположные стороны на величину шага оребрени . На стенке корпуса 1 с его внутренней стороны в плоскости перегородки 4 и в контакте с ней размещено упругое кольцо 6 с внутренней канавкой под перегородку. 3 ил.The invention allows to intensify heat exchange between media. The heat exchanger comprises a housing 1 with a bundle of heat exchanging tubes 2 with screw finning mounted inside the tube plates and transverse segment partitions 4 located in the annular space with openings for the tubes 2. The partitions 4 are thin-walled. Each hole in the partitions 4 has a diameter smaller than the outer diameter of the fins. In the zone of each hole, the partitions have a radial cut along the axis of the hole, the edges of which are bent in opposite directions by the fin pitch. On the wall of the housing 1 from its inner side in the plane of the partition 4 and in contact with it is placed an elastic ring 6 with an internal groove under the partition. 3 il.

Claims

Claim

A heat exchanger comprising a housing with a bundle of heat exchanger tubes with screw fins located inside, fixed in tube boards, and transverse segmented partitions located in the annulus with holes for pipes, characterized in that, in order to intensify heat transfer when making partitions are thin-walled, each hole in the partitions made with a diameter smaller than the outer diameter of the fins, and the partition in the area of the hole has R. adial in contact with the latter placed an elastic ring 6 with an inner ring avkoy under the partition 4.

When assembling the bundle, pipes 2 with screw fins are screwed into the transverse segmented partitions

4. In this case, the interval between the partitions 4 is maintained without a cut, which is not additional relative to the axis of the hole, the edges of which are bent in opposite directions by the size of the finning step, moreover, a sealing elastic ring with an internal groove
