3 in 1 Black Aluminum Heat Sink for Raspberry Pi 4B The Aluminium Heat sink for Raspberry Pi 4 is an aluminum heat sink kit that is used for cooling the chip microprocessor. The heat sink is attached with thermally conductive adhesive tape that helps in efficiently cooling the Raspberry Pi. This Raspberry Pi heat sink kit's design aims to enhance the surface area that comes into contact with the air or other cooling medium. A heat sink is used to transmit thermal energy from a high-temperature device to a low-temperature fluid medium. The fluid medium is frequently air, but can also be water, refrigerants, or oil. If the fluid medium is water, the heat sink is frequently called a cold plate. When the airflow through the heat sink decreases, this results in an increase in the average air temperature. This in turn increases the heat sink base temperature. Additionally, the thermal resistance of the heat sink will also increase. The net result is a higher heat sink base temperature. Installation Method All you need to do is remove the heatsink protection and stick and place it on the raspberry pi. The heat sink has an adhesive film on the back that is easy to mount on the BGA chip by pressing it gently. The heatsink will stick to the BGA chip and cool it. Note: Iotcart is the authorized sellers of Raspberry Pi products in India. Therefore even if you are in Bangalore, Hyderabad, Kerala, Mumbai or Pune, you can buy Raspberry Pi Heatsinks online from Iotcart at the comfort of your homes.
