一、前言在批林整风运动的推动下,我国工农业生产蓬勃发展。新技术、新产品、新工艺不断涌现。铝质板式换热器这一新产品,几年来在航空、化工、制氧机等方面的应用日益广泛。在我国铁路上,近几年有关单位陆续研制了一批铝散热器、铝中冷器,并装用在内燃机车上。随着设计和冷、热加工工艺的不断改进,铝散热器的性能、质量和使用寿命都有很大的提高。遵照毛主席关于“备战、备荒、为人民”的指示,为了使铝散热器早日上马,推广应用, I. Introduction The promotion of industrial and agricultural production has been booming under the impetus of the campaign of rectifying forests and rectification. New technologies, new products and new processes are emerging. Aluminum plate heat exchanger this new product, over the years in the aviation, chemical, oxygen and other aspects of the growing use of. In our country’s railway, in recent years, relevant units successively developed a number of aluminum radiators and aluminum intercoolers and installed them on diesel locomotives. With the design and continuous improvement of cold and hot processing technology, the performance, quality and service life of aluminum radiator have been greatly improved. In accordance with Chairman Mao’s instructions on “preparing for war, preparing for famine and for the people”, in order to launch the aluminum radiator as soon as possible and promote its application,
