Plate configurations in single and multi-process plate heat exchangers

The plate heat exchanger has many applications, and the specific working conditions determine its process configuration, mainly single-process and multi-process configuration, the specific use of which configuration to be determined according to the actual working conditions, then single-process and multi-process design of the plate configuration of what exquisite?

The application scope of plate heat exchangers can be divided into several categories, mainly the HVACR industry, petrochemical and natural gas industry, beer and beverage industry, paper industry, pharmaceutical industry, power generation industry, each industry on the use of plate exchange are not the same, is said to be the single process and multi-process.

Plate heat exchanger by a group of corrugated metal plate composition, are equipped with interface holes for the two sides of the temperature difference between the inflow and outflow of fluid. Heat transfer takes place between the two media through the heat transfer plate plates. The set of plates is assembled between the fixed clamping plate and the movable clamping plate and is pressed down by fastening bolts. The plates are equipped with sealing gaskets, which seal the inter-plate channels and allow fluid to flow into the adjacent channels. The plate ripples cause turbulence and support the plates against differential pressure.

There are only two plates in a single-flow configuration that do not transfer heat, the head and tail plates. The single flow has a blind plate attached at the end, which is a plate with four corner holes sealed to prevent contact between the medium and the clamping plate.

Multi-flow configurations can be created through the use of steering plates without perforated ports. This is primarily to change the direction of flow of one or both fluids. Multi-flow can be used for processes where the media requires slower heating resulting in longer heating times. Four ports are formulated on either side. For example, in a two-flow configuration, there are three plate plates that do not transfer heat.

The plate heat exchanger single and multi-processconfigurations are achieved using a combination of plates designed to use different conditions to reduce costs as much as possible.
