Automotive aluminum heat sink die casting<\/a> is a very common processing technology in automotive manufacturing, and has an important role in the manufacture of automotive parts. Automotive heat sink is the main machine parts in the automotive cooling system, is a pressure casting parts, is the use of die casting machine installed casting mold, will be heated to liquid aluminum alloy poured into the die casting machine inlet, die casting machine die casting, manufacturing mold restrictions on the shape and size requirements of the aluminum alloy automotive parts.
The role of automotive aluminum heat sink is to absorb and distribute the heat energy generated by the car engine. Aluminum heat sink has good thermal conductivity, can effectively transfer the engine heat to the outside world, to maintain the normal operation of the engine. Aluminum alloy material has excellent thermal conductivity, small specific gravity and processability. Automotive aluminum die casting heat sink is widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, oil pump manufacturing, transmission machinery manufacturing and other automotive components.<\/p>\n\n\n\n

Working Principle<\/h3>\n\n\n\n

The working principle of automobile heat sink is mainly through the flow of coolant in the radiator core, the heat generated by the engine will be transferred to the heat sink, and then the heat will be emitted to the air through the heat sink to ensure the normal operation of the engine. Specifically, the heat sink is usually made of thin sheets of aluminum or metal arranged into tiny grooves. When the coolant flows through the heat sink, it has a large area of contact with the heat sink, allowing the heat to be radiated into the air. In this process, the hot coolant becomes cooler as it dissipates heat to the air, and the cold air warms up as it absorbs the heat dissipated by the coolant.<\/p>\n\n\n\n

Additionally, heatsinks can emit heat into the air by either natural convection or forced convection. Natural convection refers to the flow of air through the radiator core in its natural state, while forced convection refers to the flow of air through the radiator core by means of a fan or other forced means.<\/p>\n\n\n\n

    Automotive aluminum heat sink material selection<\/h3>\n\n\n\n
      \n
    1. Good thermal conductivity: as a heat sink, its basic function is to quickly transfer the engine heat to the outside world, so it needs to have excellent thermal conductivity.<\/li>\n\n\n\n
    2. High-temperature strength: able to maintain good strength and stability at high temperatures to ensure that no deformation or damage occurs during the work of the automobile engine.<\/li>\n\n\n\n
    3. Corrosion resistance: able to resist the vibration, high temperature and corrosive substances generated in the process of automobile operation, to ensure the durability and reliability of the heat sink.<\/li>\n\n\n\n
    4. Processability: easy to die-casting, machining and surface treatment and other manufacturing processes to facilitate mass production.<\/li>\n<\/ol>\n\n\n\n

      At present, the main materials used in automotive aluminum heat sinks include aluminum alloy and stainless steel. Among them, aluminum alloy has better thermal conductivity and processability, and is a commonly used heat sink material. Stainless steel has good high-temperature strength and corrosion resistance, in some special circumstances can replace aluminum alloy as a heat sink material.<\/p>\n\n\n\n
