New Invention: Double-Pipe Stream Heat Exchanger

An inventor from Russia presented at the International Exhibition of Inventions of Geneva 2014 the invention: “Double-pipe stream heat exchanger”.

This invention relates to heat-exchange equipment and it can be used in various segments of industry, agriculture and utility services.

Novelty of technical solution

Internal baffles are concentrically located in the heat-exchange pipe dividing tubular annulus into input and output cavity and it also has holes on the surface, which are used for the input of environment to the cavity between heat-exchange pipe and internal baffle.

Effect of the use

Use of the invention allows intensifying heat exchange due to the almost complete removal of the boundary layer from the outer and inner surfaces of heat-exchange pipe. it increases thermal transmission coefficient up to 10 and more times and accordingly required heat-exchange surface, steam heat-exchange length, its weight and dimensions are reduced.
