Casing for DCDC

thingiverse

I was in desperate need of a reliable power unit for my laptop, one that could deliver a stable 12V output without fail. Two commercial units I tried earlier just didn't cut it, so I decided to take matters into my own hands and search for a more suitable solution. That's when I stumbled upon a Chinese-made 200W DC-DC converter that exceeded my expectations in every way. Not only did it deliver twice the power I needed, but it also stayed remarkably cool, rarely getting warm even during extended use. The unit itself is a sturdy piece of engineering, with no free holes for mounting and a heat sink that requires careful handling to avoid damage. To address this issue, I simply pressed the PCB firmly against the top of the case, ensuring a secure fit while keeping the edges of the heat sink safely out of reach to prevent accidental contact. As an added precaution, I routed the wires through Z-type slots for strain relief, providing an extra layer of protection against damage or wear. The only minor adjustment I made was expanding the opening for the heat sink by hand, as it had been slightly too small for my needs. Additionally, I needed to source M3 bolts with a length of 55mm, which proved to be a challenging task - but ultimately, I found what I needed and managed to complete the project successfully. While there's certainly room for improvement, I'm satisfied with the results and don't see a need to invest in a second case anytime soon.
