Fractal bifurcated heat exchanger with coupled jacket

Abstract

The invention provides a coupling jacket type fractal branching structure heat exchanger. The coupling jacket type fractal branching structure heat exchanger at least comprises an outer shell, an inner shell, a jacket layer, a first pipe plate, a first end socket, a second pipe plate, a second end socket, a main pipeline and fractal branching structure heat exchange pipe bundles, wherein the inner shell is arranged in the outer shell; the jacket layer is formed between the inner shell and the outer shell; the pipe plates and the end sockets are arranged at two ends of the outer shell; through holes which correspond to the position of the jacket layer are formed in the second pipe plate; one end of the main pipeline penetrates through and is fixed to the first end socket and the first pipe plate; the fractal branching structure heat exchange pipe bundles are arranged in the inner shell, the center parts are communicated with the main pipeline, and the tail ends are communicated with the jacket layer through a hole body in the inner shell. The coupling jacket type fractal branching structure heat exchanger provided by the invention has the advantages that a material collection problem in the prior art is solved, the heat transfer ability is substantially increased, the pressure drop of a system is reduced, and the technical purposes of high heat transfer ability and energy conservation are reached.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a coupled jacket type heat exchanger with fractal bifurcation structure. Background technique [0002] Heat exchanger is an indispensable equipment to realize heat exchange and transfer in the process of industrial production. Lots of applications. According to reports, 80% of the energy transfer in the chemical industry is undertaken by heat exchangers. In 2008, the total market size of the world's heat exchanger industry was around US$50 billion. Among them, the two major markets of the European Union and the United States account for about 20 billion US dollars, accounting for nearly 40% of the global heat exchanger market, and the Chinese heat exchanger market is 5.5 billion US dollars, accounting for 11% of the share. Due to the rapid growth of China's economic development, it will still be the main incremental market for the heat exchanger industry in the future. [0003] A...
