Product Description

The cost of aluminum die-cast heat sink is mainly composed of die-casting molds, raw materials, machining and surface treatment. The mold cost is high, but it is suitable for mass production. The shape of die-cast radiators is more diverse than that of aluminum extrusion radiators, and the design is also more diverse.

The production process of radiator is to melt aluminum ingots into liquid, fill them into metal models, and directly die-cast them with a die-casting machine to make heat sinks. The die-casting method can make fins into various three-dimensional shapes. The heat sink can be made into complex shapes according to needs, or it can be made into heat sinks with diversion functions according to the fan and airflow direction. It can be made into thin and dense fins to increase the heat dissipation area. It is widely used because of its simple process.

casting aluminum

Aluminum castings are produced from aluminum materials using aluminum die-casting technology. Aluminum is famous for its durability, high strength, corrosion resistance and wide use in custom-designed metal products.

industrial heat sink

As a professional heat sink supplier, HY has an independent mold design and manufacturing center. All molds are independently produced and continue to develop towards high technology and high performance. High-quality materials are selected, the structure is tight, multiple strict process inspections, and a professional design team are used to support customized production.

In which industries are heat sink used?

1. Computer Processor

Computer processors (CPU) generate large amounts of waste heat during operation. Featuring a copper heatsink with an active cooling fan. Allows the CPU to run more efficiently.

2. LED lighting

LED lamps generate a lot of waste heat when lighting, and small LEDs usually use passive heat sinks.

3. Electronic equipment

Electronics convert alternating current into direct current. During this conversion process, some waste heat will be generated, and long-term use will shorten the life of electronic equipment. Heat sinks on electronic equipment often use aluminum die-cast heat sinks

4. Automobile industry

In addition to heat sinks for vehicle control circuits, the role of the heat sink is to keep the electric motor cool during operation.

5.Aerospace

Heat sinks are commonly used in the aerospace industry on control equipment to transfer heat into the vacuum of space.
