Problems solved by technology

Among them, in the existing mechanical equipment manufacturing process, most of them independently design and manufacture a heat dissipation device equivalent to the heat dissipation requirements of mechanical equipment; moreover, most of the existing heat dissipation devices are formed by casting, and the efficiency of casting processing is not only Low, and its processing cost is also very high, such a process will lead to a great increase in the manufacturing cost of mechanical equipment and a decrease in efficiency

Although heat sinks can now be purchased separately, it is generally difficult to achieve unity with the heat dissipation needs of mechanical equipment. In order to avoid excessive heat accumulation on mechanical equipment, companies have to purchase heat sinks with high heat dissipation effects; and The cost of hooking in a cooling device with high heat dissipation effect is generally higher, which also easily leads to an increase in the cost investment of the enterprise

In addition, some mechanical equipment will have a large change in the calorific value under different age groups; the calorific value generally increases with the increase of the use time; because most of the existing heat dissipation devices are made of aluminum The alloy is integrally cast, so the heat dissipation effect of the heat sink is limited, and the heat dissipation of the heat sink cannot be changed according to the needs. In this way, when the heat generation of the mechanical equipment becomes greater than the heat dissipation effect of the heat sink, it is easy to cause the use of mechanical equipment. greatly shortened lifespan

At the same time, when the heat sink made of integrally cast aluminum alloy is damaged, the entire heat sink has to be replaced, which will greatly increase the maintenance cost of the enterprise
