FLUID HEATING-COOLING CYLINDER DEVICE

摘要

A compact fluid heating device to heat large quantity of gas or liquid at low costs hasn’t existed. A fluid passage is provided to form a grooved fluid passage for fluids on the lateral surface of a metal cylinder and to allow fluids to vertically collide with the wall of the next fluid passage after passing a narrow fluid passage without creating a stagnant layer. The present invention performs heat exchange for small spaces in a moment and facilitates the production of the structure.
