Geekworm design this Raspberry Pi 4 Model B embedded armor aluminum alloy heatsink to slove Pi 4 excessive heat generation problem when use Raspberry Pi 4 Model B with its expansion board. This heatsink can also be used with a cooling fan above.
Why design this product?
Why is it compatible with the use of expansion boards?
- After the Raspberry Pi 4 was released, we found that the heat generation of Pi 4 also increased greatly with its performance. We have encountered many times that Pi 4 crashed due to excessive heat generation. This problem can be satisfactorily solved by use the Raspberry Pi 4 armor case: if not use other Pi 4 external expansion board.
- At the same time, we found that various types of Raspberry Pi 4 expansion boards such as DAC+, UPS HAT, or various LCDs on the market also encountered excessive heat generation when used on Pi 4. So we try to solve this problem.
- We refer to the design of Raspberry Pi 4 armor case and simplified the design , so there is the birth of this Embedded Armor Aluminum Alloy Heatsink Radiator.
- The Embedded Armor Aluminum Alloy Heatsink Radiator is 7mm high (designed with negative tolerance) and is equipped with M2.5*5+5 copper spacers; so the total height is 12mm, which can support most of Raspberry Pi 4 expansion boards; if you use expansion board with other height, you only need to replace the copper spacers with the right height. (If you need a special height copper spacers, please contact us.)
- The raspberry pi hat positioning hole has internal thread for easy fixing from above or below;
- Compared to the raspberry pi PCB, the entire heat sink shrinks inward by 0.5 mm.
- Only supports Raspberry Pi 4 Model B;
- Supports to cooling down the Raspberry Pi 4 board when using the Pi 4 expansion board;(NOT support PoE expansion board)
- Equipped with a variety of screws and copper spacers;
- Raspberry Pi HAT positioning hole is M2.5 internal thread; (this design is convenient to fix)
- Supports the installation of 25mm fans; Cooling fan can be added when the heat dissipation of a single aluminum heat sink is not enough, so that all heat dissipation problems can be solved.
- Heatsink Dimensions: 6.5x5.5x0.7cm/2.55x2.16x0.27inch
- 1x 7mm armor heatsink(P165-A)
- 4x M2.5x5+5mm spacers
- 1x thermal tape (cut for CPU and RAM)
