Heat exchangers should provide intensive heat exchange between liquids, be safe and reliable in operation, compact in size, not metal-intensive, convenient for installation, maintenance and repair.
On the intensity of heat exchange area affected by the heat transfer surfaces are generally reflected in the stamp unit; the temperature difference between the media; characteristic of the material; shape, color and surface roughness; the degree of contamination of the heat exchange surface; the speed of movement of media involved in heat exchange; thermophysical properties of the media participating in the heat transfer (the ability of the medium to give or absorb heat).
