Copper Pin Fin Heatsink Quotation Request From The Korean Customer

  Today , Sinda Thermal team received an inquiry for the copper pin fin hatsink, it isfor LED cooling application .The heatsink material is copper, with round fin design. he integrated structure provide the better thermal performance and higher reliability.Thanks for the inquiry , we will sent the quotation price to customer by tomorrow.

  The forging process is formed by heating the aluminum block to the yield point and filling the die with high pressure. Its advantage is that the fin height can reach more than 50mm and the thickness is less than 1mm, the maximum heat dissipation area can be obtained in the same volume, and it is easy to obtain good dimensional accuracy and surface finish. However, during forging, due to the necking phenomenon during cooling plastic rheology, the heat sink is easy to have uneven thickness and height, which affects the heat dissipation efficiency. Due to the low plasticity of metal, it is easy to crack during deformation and large deformation resistance, large ton (more than 500 tons) forging machinery is required, and the high cost of equipment and die leads to high product cost. And because of the high cost of equipment and molds, the cost is too high unless for high volume mass production.
