A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger 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. Plate heat exchangers are now common and very small brazed versions are used in the hot-water sections of millions of combination boilers or heat pump. The high heat transfer efficiency for such a small physical size has increased the domestic hot water (DHW) flowrate of combination boilers or heat pump. The small plate heat exchanger has made a great impact in domestic heating and hot-water. Larger commercial versions use gaskets between the plates, whereas smaller versions tend to be brazed.

FAQ

How to calculate heat transfer capacity between both fluids?

Firstly, we need know what medium on both sides. It will get know specific heat each fluid. Secondly, we need know flow rate on both sides in order to calculate mass flow. Thirdly, we need know temperature difference between inlet and outlet on the both side.

How to select correct plate heat exchanger by heat transfer capacity?

It still need define:1.) pressure drop and 2.) inlet and outlet diameters on both sides because it affect flow capacity?

Do there have other restrictions on PHE selection?

Yes, main restrictions as bellowing: 1. PHE Max. and Min. working temperature 2. PHE Max. working pressure 3. Medium Corrosions 4. anti-freeze and dirty block 5. Other harzard working condions Please consult BOWA SOLUTION about more details
