Aluminum radiator has been developed in the 1980 s, 90 s, our country pay close attention to product development of aluminum alloy heat sink, aluminum radiator in China during this period of research and development and patent project declaration is very active, then mainly aluminum welding extrusion molding products. As the combination of monolithic die-casting aluminum products abroad to enter, began appearing in our country also die-casting aluminum and the trial production of the die casting aluminum radiator products.
Die casting aluminum radiator has a very distinctive features, it is assembled monolithic split structure, module assembly, the overall is very light, easy to use, strong adaptability, good cost performance. Followed by the appearance of integral feeling is strong, exquisite and smooth surface, good plane, and is different from the original cast iron plate radiator, the unique structure of beauty; The third has a good heat transfer performance, superior to the traditional cast iron radiators. Is good for die casting aluminum radiator, some with larger capacity ability of enterprises, in the international market as the goal, to exercise the enterprise competitiveness and product manufacture craft level; 2 it is to meet the needs of market development, application on the basis of past experience and lessons, and guide the use and sustainable development of science, in the die casting aluminum radiator industry standard in our country is developing; Three is the product update steadily reflect the market demand. The aluminum radiator products made of extruded aluminum welding column type radiator, evolution to the die casting aluminum radiator, and achieved rapid growth, it is the inevitable outcome of the development of product quality.
But die casting aluminum radiator also facing the development bottleneck, is embodied in the die casting aluminum radiator products in our country’s engineering application, the more water is leaking. Foreign die casting aluminum radiator products price is higher, and durability performance is not good. The correct application of domestic, but also to be solved; 2 it is to die casting aluminum radiator is strict to the requirement of heating water quality, but different from steel. Take inner surface coating to protect, the method of reliability is not high. Three is the product innovation is insufficient, me-too development stage, Chinese die casting aluminum radiator need with independent intellectual property rights and other issues.
Extruded aluminum welding heat sink, for example, application of aluminum alloy heat sink, must satisfy three necessary conditions: the first is the neutral water quality is a important condition; Followed by the material specification, and shall not use less known and inferior brand aluminum; The third is the production process, welding. Related standards in our country, shall be specified for the engineering application of aluminum alloy heat sink, is very careful. The vast domestic market, can go a long way, but you can’t do everything. Our enterprises must pay attention to brand construction, improve the level of production technology, product innovation and marketing service levels. Efforts to create suitable for China’s conditions, the high quality and durable die casting aluminum radiator.
