China Drying Network Recently, a low-resistance lowering heat exchange tube bundle device developed by Luoyang Longhua Heat Transfer Energy Saving Co., Ltd. has won the national utility model patent. The new structure is suitable for applications where the flow rate of the cooled medium is low and the pressure drop is demanding.
The inlet and outlet ends of the device are disassembled to disassemble the pipe box. The pipe box can be round, rectangular or other shapes. The inlet and outlet pipe box closures and the pipe box tube plate are connected by fasteners. The sealing surface is in the form of a protruding surface, a grooved surface, and a convex-concave surface. The decomposition of the tube box structure avoids the coexistence of the same hot and cold mediums. The resulting thermal stress; when the heat exchange tube bundle rotates with multiple strokes, it is equipped with a floating design of the rotary end tube box. The tube box adjustment plate is specially processed and can be floated along the frame with the adjustment box of the tube box under thermal stress, which can effectively improve the stress concentration caused by the thermal expansion when the hot fluid flows in, and make the heat exchange tube have a certain degree of inclination to ensure the medium at a low flow rate. Under the smooth outflow.
