Plate Heat Exchanger in Industry Application

The plate heat exchanger is used more widely in industrial applications. But in the heat exchanger design, there are some details that need to be paid attention to. So today we're going to introduce these details. 

1. Design indexes. The design index of the heat exchanger includes the working fluid and flow rate, inlet and outlet temperature, working pressure, and heat transfer efficiency. The heat exchanger for aerospace equipment shall also have the allowable pressure drop, size, and quality, etc.

2. General layout. Select the type and structure of the heat exchanger, the form of fluid flow, and the materials first, and then select the type of heat transfer surface. Operating temperature and pressure should also be considered.

3. Thermal design. The heating design of the heat exchanger includes heat transfer calculation, flow resistance calculation, and size determination. In addition to technical performance indexes, heat transfer surface characteristics (including heat transfer characteristics, flow resistance characteristics, and structural parameters) and thermal physical properties of fluids and materials are also required. The optimization technology can be applied to the heat exchanger design, according to the design objectives, for the selected various heat exchanger forms and heat transfer surface through different angles of the optimization analysis to provide several alternative schemes.

4. Choice of a design scheme. After the thermal design and structural design of the heat exchanger are completed, the designer makes the final choice according to various conditions. Conditions of mold manufacturing, brazing furnace size, shipping restrictions, delivery dates, company policies, and competitive intensity will affect the final selection.
