Efficient heat exchanger and application thereof

Abstract

The invention discloses an efficient heat exchanger and application thereof. The efficient heat exchanger comprises at least one set of heat exchange assemblies arranged in the heat exchanger and is characterized in that each heat exchange assembly comprises an outer pipe and an inner pipe arranged inside the outer pipe; the position between inner pipes as well as the position between each inner pipe and the corresponding outer pipe are each provided with a runner for allowing a medium to flow; each runner is internally provided with a swirling flow field device for enabling the medium in the runner to generate swirling flow; and at least one of the swirling flow field devices can make swirling flow centrifugal force or swirling flow centripetal force generated by the medium in the runners directly act on the heat exchange surfaces inside the runners. The efficient heat exchanger is reasonable in design, simple in structure, small in flowing resistance, high in heat exchange efficiency, economical, practical and suitable for industrialized popularization.

Description

technical field [0001] The invention relates to the field of heat treatment equipment, in particular to a high-efficiency heat exchanger and its application. Background technique [0002] At present, heat exchangers are widely used in oil refining, chemical industry, light industry, pharmaceuticals, machinery, food processing, power and atomic energy industry sectors, refrigeration, and heating. Due to the generally low heat transfer efficiency of traditional heat exchangers, materials and energy The waste is serious, and a series of problems such as low resistance, anti-scaling, convenient maintenance, and pressure resistance cannot be taken into account. At the same time, traditional evaporative air coolers will generate a large amount of water vapor (commonly known as white smoke) in the transition season, and the water vapor in the transition season is It is one of the potential factors that aggravate the smog phenomenon, so it is necessary and far-reaching to update the...

[0002] At present, heat exchangers are widely used in oil refining, chemical industry, light industry, pharmaceuticals, machinery, food processing, power and atomic energy industry sectors, refrigeration, and heating. Due to the generally low heat transfer efficiency of traditional heat exchangers, materials and energy The waste is serious, and a series of problems such as low resistance, anti-scaling, convenient maintenance, and pressure resistance cannot be taken into account. At the same time, traditional evaporative air coolers will generate a large amount of water vapor (commonly known as white smoke) in the transition season, and the water vapor in the transition season is One of the potential factors that aggravate the smog phenomenon, so it is necessary and far-reaching for the technical update of traditional evaporative air coolers and their heat exchangers
