Pinlis type double heat exchanger

What is Finlis Type Double Heat Exchanger? 

▶ Maximum Heat Transmission Area

The new concept consists of a pin-type double polyhedral heat exchanger consisting of a double tube,
a thermal medium, and a thermal medium.
This technique maximizes the heating area by allowing the fluid to flow to the flow path between 
the inner tube and the outer tube.
As a result, increased heating footprint increases energy efficiency and reduces costs.

▶ 3-D dual heat exchangers

The heat of the burn or the waste heat is heated to the inside of the inner
piping and the outer pipe, and the heat of the heat flows to the flow path.
Heat turbulence forming turbulence in the space flow to ensure rapid heat exchange.
The effect of heat transfer is maximized.

It features the characteristics of a multI-heating heat exchanger and the effectiveness of plate heat
exchangers simultaneously
