In the 1980s, my country developed aluminum radiators; in the 1990s, my country paid great attention to the product development of aluminum radiators. During this period, my country’s aluminum radiators were very active in research and development and the application of patent projects. Extruded aluminum profile welded products. With the import of foreign monolithic combination die-cast aluminum products, my country has also begun to produce die-cast aluminum and non-die-cast aluminum radiator products. In November 2000, Tianjin Fule brand aluminum alloy radiators suffered continuous cracking and running water accidents in Beijing due to the wrong material selection. The residents suffered huge losses. The front pages of various newspapers were serialized and became hot news in Beijing for a while. Since then, the company has closed down. Imported die-cast aluminum radiator products such as cards, which are used in our country, have also experienced continuous water leakage.

For a long time, industry organizations have been paying attention to the promotion and application of light-duty radiators, organizing industry-related experts to study key issues on anti-corrosion mechanisms, and establishing my country's aluminum radiator anti-corrosion test and research base in Lanzhou to support the research and development of internal surface coatings. Promote various coating protection technologies, promote the application of passive anti-corrosion technologies, and promote composite metal radiator products. At the same time, actively promote the scientific management of heating water quality.
The "Eleventh Five-Year Development Plan for China's Heating Radiator Industry" released in 2006 specifically put forward the requirements of "clear positioning, reasonable selection, and safe use" for the development of aluminum radiators. To this end, the industry association actively organizes the compilation of industry standards for die-casting aluminum alloy radiators to standardize product quality and develop the domestic market in a scientific and reasonable manner.
Die-cast aluminum radiators have very distinctive features. First, they have a single-piece split assembly structure and module assembly. The whole is light, easy to select, adaptable, and cost-effective; secondly, the overall appearance is strong, the surface is fine and smooth, and the flatness is good. And it has a unique structural beauty that is different from the original cast iron fin type radiator; the third is that it has good heat transfer performance, which is better than traditional cast iron radiators. At present, some die-cast aluminum radiator companies with large production capacity have taken the international market as their goal, and have exercised their competitiveness and product manufacturing technology. Products are steadily updated and market demand is increasing. At present, the product type of aluminum radiator is a column-wing radiator made by welding extruded aluminum profiles, which has evolved to die-cast aluminum alloy radiators, and has grown rapidly. This is an inevitable result of the development of high-quality products.
However, die-cast aluminum radiators are also facing development bottlenecks.
Take the extruded aluminum profile welding radiator as an example. The promotion and application of aluminum radiator must meet three necessary conditions: firstly, it must be used in neutral water quality; secondly, it must be standardized material, and no other brand aluminum shall be used; and then the production process, welding. The "Technical Regulations for Water Quality and Anticorrosion of Heating Systems" should be carefully studied. In the relevant standards of our country, there are clear regulations on the engineering application of aluminum radiators, and the application of this product should be very cautious. The domestic market is vast, and die-cast aluminum radiators can do a lot, but they can’t do whatever they want. Summarizing the lessons learned from the promotion of die-cast aluminum products in our country’s engineering promotion, the author believes that the main reason is that "the foreigners cannot be transformed". Lessons should be remembered and past mistakes should not be repeated; a product can make an enterprise grow, destroy an enterprise, or even hurt another industry. Enterprises must pay attention to brand building, improve the level of production technology, product innovation capabilities and marketing services, and strive to achieve the "Eleventh Five-Year Development Plan for China's Heating Radiator Industry" for the "clear positioning, reasonable selection, and safe use of this product" "The development goal is to create a high-quality and durable die-cast aluminum radiator suitable for my country's national conditions. The author suggests that the development path of die-cast aluminum radiators should be based on independent heating and overall contracting, and that engineering applications should be carefully considered under the conditions of protection and reliability and secondary heating. It is hoped that some die-cast aluminum production enterprises can quickly grow into famous-brand enterprises in my country's die-cast aluminum radiator.
