Aluminum heat sink have been developed in the 1980s. In the 1990s, China paid great attention to the development of aluminum heat sinks, mainly for extruded aluminum profile welding products. With the entry of foreign monolithic die casting aluminum products, Domestic also began to appear die-casting aluminum and non-die-casting aluminum radiator products trial-manufacture.

Die-casting aluminum heat sink has very distinct characteristics, it is a monolithic assembly structure, module assembly, the whole is very light, easy to choose, strong adaptability, good performance and price ratio, followed by the appearance of the overall sense of strong, delicate and clean surface, good planarity, Moreover, it has a unique structure aesthetic feeling different from the original cast iron heat sink and the third has good heat transfer performance, which is superior to the traditional cast iron radiator.

Die casting aluminum heat sink development bottleneck, first is with more water leakage , foreign die casting aluminum heat sink products price is a little bit higher, and with bad durable;Secondly is with strict for heating water quality requirements, but unlike steel, coating on the inner surface protection methods, the reliability is not high;Third the product innovation is insufficient, In the stage of imitation follow up development , Chinese die casting aluminum heat sink need with independent intellectual property rights and other issues.
