Heat Sink

Die casting is a processing method in which molten alloy liquid fills the cavity of a steel mold at high speed under the action of high pressure, and solidifies the alloy liquid under pressure to form a casting. The cost of a die-cast heat sink mainly consists of the die-casting mold, raw materials, and machinery. Processing and surface treatment,  the mold cost is high and suitable for mass production. The shape of the die-cast radiator is more diverse than the aluminum extrusion radiator, and the design is more diverse.

The production process of aluminum die-casting heat sink is to melt the aluminum ingot into a liquid state, fill it into a metal model, and use a die-casting machine to directly die-cast it to form a heat sink. The die-casting method can be used to make the fins into a variety of three-dimensional shapes. The heat sink can be made into complex shapes according to the needs, and can also be made into a heat sink with a diversion effect according to the fan and air flow direction. Thin and dense fins can be made to increase the heat dissipation area. It is widely used because of its simple process.

Aluminum castings are produced from aluminum materials using the aluminum die-casting process. Aluminum is known for its durability, high strength and widespread use in custom designed metal products.

There are many aluminum die-casting processes, each with unique characteristics. Therefore, aluminum parts with different properties require different aluminum die-casting processes. The radiators produced by HY are made of aluminum die-casting. This process is often used in the automotive, aerospace, construction, shipbuilding and other industries.

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.
