Plate-fin Heat Exchanger (PFHE)

Shen's Plate Heat Exchanger is divided into PCHE,PFHE and H2X, in which plate-fin heat exchanger (PFHE) is a heat exchanger plate superimposed by stamping fins or fine processing (channel diameter is 2~5mm), and the exchanger is welded by vacuum diffusion. The heat exchanger of this structure has the advantages of high and low temperature resistance, corrosion resistance and high heat exchange efficiency compared with the traditional heat exchanger, although the pressure resistance is not as good as PCHE, the pressure loss is smaller, and it is more suitable than PCHE in some fields.PFHE heat exchanger uses diffusion welding technology, the special plate fin structure makes the heat exchange efficiency greatly increased at the same time, the cost is much lower than PCHE, compact structure makes the system volume is greatly reduced, the heat exchanger plays a key role in the system energy conversion and transmission process, its efficiency directly affects energy consumption and carbon emissions. Shen's continuous optimization of heat exchanger design can improve energy efficiency, reduce energy consumption and greenhouse gas emissions, so as to achieve the goal of green development.

Case Story

SOFC Thermal Management System High Temperature Heat exchanger Solutions

With the increasing exhaustion of energy and environmental deterioration, the development and utilization of efficient and clean new energy will become an important choice for energy development in the 21st century. Solid oxide fuel cell (SOFC) is an all-solid-state electrochemical power generation device that converts chemical energy in fuel and oxidizer directly into electrical energy. The energy conversion efficiency is high, which can reach about 60%. The generated heat for cogeneration efficiency can reach more than 80%, is currently the most cutting-edge, but also the most technically difficult new fuel cell, the world's developed countries generally regard it as a strategic reserve technology. The FPHE printed plate type micro-channel heat exchanger developed by Shen's technology has been applied in many cases on SOFC and SOEC systems. In recent years, the company has continued to make efforts in this field, polishing product quality and expanding market share.

Titanium Intercoolers For Ships And Marine Engines

Shen's Technology and Weichai cooperated to develop the Marine titanium alloy intercooler and applied it to the Marine power system. The titanium alloy intercooler developed by Shen's technology adopts plate-fin structure, and the heat exchanger core is formed by vacuum diffusion welding. The principle is to apply appropriate pressure and temperature to several layers of metal sheets of different thicknesses after the flow path and shape processing, so that the metal surface is fully combined. The core made by this welding method has the advantages of no joint, no weld, no any other type of potential fault point, and its strength after welding can reach more than 95% of the base material to ensure the excellent performance of the product.
