  evaporator   consist of stainless steel plate packs, which have embossed chevron patterns. The plates are turned 180 degrees to each other, causing the plate ridges to intersect and creating a lattice of intersecting channels. Fluids can flow in counter-current and co-current way. The entire construction is nondismountable and scaled together by means of brazing in a special vacuum furnace.

Major advantage over a conventional   evaporator in that the fluids are exposed to a much larger surface area because the fluids spread out over the plates. This facilitates the transfer of heat, and greatly increases the speed of the temperature change.  evaporator are now common and very small brazed versions are used in the hot-water sections of millions of combination boilers. The high heat transfer efficiency for such a small physical size has increased the domestic hot water (DHW) flowrate of combination boilers. The small   evaporator  has made a great impact in domestic heating and hot-water

How  evaporator  Works:

Heat transfer occurs when there is a difference in temperature between two mediums. Heat will travel from the hot source to the cold source. The rate at which the heat transfer occurs at is determined by many factors such as the heat conductivity of the two materials and the difference in temperatures of the two mediums. Convectiuve heat transfer occurs when the materials are moving against each other

Corrosion protection for evaporator   stainless steel has a high resistance to most chemicals but is sensitive to chloride ion concentration so this must be limited to 280ppm or less(lower than 55 C),the copper used in the brazing process is mainly sensitive to strong acid and ammonia so the PH must be maintained between 6 to 8.in practical application.for example,hydrochloric acid should never be used to clean the brazed plate heat exchangers;if evaporator   are applied in seimming pool heating,limite chloride ion concentration to 280ppm in the water;what's more,in chemical,pharmacy and other industries,solutions containing strong acid like hydrochloric acid and harshorn won't be proper fluid medium
