Low fin type heat exchanger

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.

Description

technical field [0001] The invention belongs to the technical field of heat exchange and relates to a low-fin heat exchanger, in particular to a high-efficiency and low-consumption low-fin heat exchanger. Background technique [0002] Heat exchangers are mainly used for heat exchange in the chemical industry, pharmaceutical industry, and environmental protection engineering industry. Now most heat exchangers use bare tubes as heat exchange tubes. Since the light tube has no disturbance to the heat transfer fluid, the flow of the heat transfer fluid is stable and the heat transfer is stable. The thermal efficiency is average. Under the condition of the same heat exchange area, the original heat exchanger occupies a larger area and requires more heat source fluid. Contents of the invention [0003] The object of the present invention is to solve the deficiencies in the prior art and provide a low-fin heat exchanger with high efficiency and low consumption. [0004] The purp...
