The invention discloses improved and strengthened heat transfer equipment. The improved and strengthened heat transfer equipment comprises a heat exchange pipe body, wherein a spiral coil is wound on the outer surface of the heat exchange pipe body; a first internal insertion object and a second internal insertion object are arranged in the heat exchange pipe body, and are welded onto the inner wall of the heat exchange pipe body through brackets; the first internal insertion object is arranged at the inlet of the heat exchange pipe body; the second internal insertion object is arranged at the outlet of the heat exchange pipe body; and the spiral coil is made of a metal material. Both the first internal insertion object and the second internal insertion object are of a spiral pipe shape. Grooves with equal intervals are formed in the surface of the heat exchange pipe body. According to the improved and strengthened heat transfer equipment, the spiral coil is wound on the outer surface of the heat exchange pipe body, so that the problem in machining of current spiral pipes that the thickness of the heat exchange pipe and the depth of the threads are limited are solved, and the heat exchange surface area is increased; and the two internal insertion objects with different specifications are adopted, so that fluid in the pipe pass is at a uniform velocity state, and therefore the film coefficient of heat transfer is kept at a high state all the time. The spiral coil and the internal insertion objects are combined for use, so that the film coefficient of heat transfer is maximized, and the strengthened heat transfer effect is optimum.
Description
technical field [0001] The invention relates to the field of chemical production equipment, in particular to an improved enhanced heat transfer equipment. Background technique [0002] Due to the rapid development of science and technology and the serious shortage of energy, the depth and breadth of the enhanced heat transfer technology research has been expanding and penetrating and developing into new fields. All major industrial countries in the world have carried out a lot of research and development work on this. The structure of the heat exchanger has been developed from the original bow-shaped partition and smooth tube to the support between the tubes and the high-efficiency special-shaped reinforced tube. The heat transfer and fluid resistance performance have been significantly improved. It has high temperature resistance, high pressure resistance, simple structure, and convenient cleaning. advantage. The structures of various special-shaped tubes are different, bu...
