The domestically produced printed plate heat exchanger (PCHE) produced recently passed the factory acceptance. Up to now, the product has set a domestic record in four aspects: power size, design temperature, pressure resistance range, and structural size.
PCHE is a subversive compact and efficient micro-channel heat exchanger. This kind of heat exchanger has the advantages of high heat exchange efficiency, low temperature and high-temperature resistance (-196℃~900℃), high-pressure resistance (60MPa), high reliability, etc. The volume and weight under the same thermal load are about the same as traditional shell-and-tube heat exchangers 1/6 of.
The successful development of PCHE broke the foreign monopoly and filled the domestic gap. For the first time in the world, electron beam bonding technology was used to complete tailored bonding of heat exchange cores, and related manufacturing technology reached the international advanced level.
The PCHE product that passed the factory acceptance this time will be used in the national demonstration project-5MWe supercritical carbon dioxide power generation test platform built in 2020.
Participating experts and representatives visited the PCHE production line on-site and learned in detail about the development and manufacturing of the first domestically produced PCHE. After full discussion, the expert group agreed that: the company has completed the design, manufacturing, and inspection of low-temperature regenerators in strict accordance with relevant regulations, standards, and product technical conditions and process requirements proposed by the owner. The products meet the requirements of the technical agreement and the product manufacturing The process is controlled, the factory materials are complete, the product quality is qualified, and it is agreed to pass the factory acceptance.
