This is a Aluminum Heatsink kit used for cooling the chips on Raspberry Pi. Comparing to other heatsinks, it has been attached with thermally conductive adhesive tape, allowing the Raspberry Pi to cool more efficiently. Are you still worried about the heat dissipation function? Do you want to have a new heat sink?
The new Raspberry Pi 4B aluminum heat sink could help you solve this trouble. These pure aluminum heat sinks include thermal tape that transfers heat efficiently to the heat sink, providing additional cooling for the IC. The contours of these heat sinks are perfectly adapted to the Raspberry Pi 4B standard.
A heat sink is designed to maximize its surface area in contact with the cooling medium surrounding it, such as the air. A heat sink transfers thermal energy from a higher temperature device to a lower 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 air flow through the heat sink decreases, this results in an increase in the average air temperature.
This in turn increases the heat sink base temperature. And additionally, the thermal resistance of the heat sink will also increase. The net result is a higher heat sink base temperature.
High quality, made of aluminum alloy, it will not be rust. The contours of these heat sinks are perfectly adapted to the Raspberry Pi 4B standard. Thermal conductive adhesive tape backing. Can be applied with other devices such as BeagleBone, VRAM VGA RAM, IC Chips, MOSFET SCR, Southbridge , Northbridge etc Reduce chip hot-spots and increase thermal dissipation surface area
