Abstract
The invention discloses a low fin type heat exchanger comprising a tube body and low fin type heat exchange tubes. Channels are arranged at the two ends of the tube body respectively, and a lug type support, a heat source inlet and a cold source outlet are formed in the side wall of the tube body. The channel close to the cold source outlet is provided with a material inlet, and the channel close to the heat source inlet is provided with a material outlet. The low fin type heat exchange tubes are connected through tube sheets and supported through baffle plates arrayed at intervals. The baffle plates are fixed through pull rods arrayed at intervals. The tube sheets are welded to the tube body, and the channels are connected with the tube body through flanges. The low fin type heat exchange tubes are adopted as heat exchange elements, so that the heat exchange area is large, meanwhile, when media flow through the surfaces of the low fin type heat exchange tubes, fins has a turbulence effect on the edge layers of laminar flows to form surface turbulent flows, and a good heat exchange effect is achieved; the low fin type heat exchange tubes are low, so that tube penetrating is convenient, flow resistance is small, differential pressure is low, needed power is low, the fin distance is reasonable, and the heat transfer effect is good.
