[FS - EU] 60mm CPU Evaporator blocks for phase change cooling.

[LordNicoll]

For sale 60mm round evaporators, 35mm tall. €180 + VAT + Shipping, for most EU countries this will work out at about €230-240.
Lightweight high surface area, these evaps are specifically designed to handle refrigerants with glide with less liquid begin sucked back to the compressor. The design impinges the flow and constricts it down at choke points to reduce pressure and ensure the components boil (Bernoulli's principle).
Come with 3D printed mounting hold downs, PLA black, and all stainless hardware (except the circlip, which has a black oxide coating).
Practical max load depends on the unit and refrigerant, but in theory with ideal conditions these should cool 500 watts easily, up to a max of around 820 watts, but that would require a decently large compressor (34cc+ for reasonably low temps).
These are the 3rd iteration of this design with a number of improvements having been made. Designed for a 10mm suction tube, can be drilled larger to 12mm for larger compressors too. Capillary tube hole is meant to be drilled out to the size needed, or drilled larger for a second tube to be brazed on which a cap tube can be brazed too if one prefers.
Sadly due to the cost of small small production of items like these from copper, the price is fairly high for these type evaporators, but hopefully I'll get some cheaper designs made soon for less demanding refrigerants. Smaller 45-50mm ones and some square ones too are in the pipelines but it depends in demand, if one of those interests you drop a reply below to let me know.
Evaps are supplied pre-pickled for brazing, but due to shipping conditions they made need another pickling wash to remove oxides. Shipping conditions can often lead to condensation. If there are any questions at all feel free to ask them. I'm currently working on getting a test unit built with one of these to demonstrate the performance but due to university I don't get a lot of time for phase building anymore.
Evaps are made in Germany from what I can tell (definitely shipped from there, made by Xometry Europe for this production run). Packed and shipped from Ireland. Warranty and returns are standard EU affair, though if you mess it up brazing it wrong; that counts as user error. Includes instructions on modifying and brazing evap but it will be assumed if you buy this you know what it is, and how to use it.
