Peltier Cooler Watercooling Mod [GUZZANTI GZ 24DD] - More efficient and powerful cooling system

prusaprinters

Since our GUZZANTI GZ 24DD wine cooler with Peltier cooling system (thermoelectric couple) was not working as it should, I  decided to modify it and replace the factory heatsink with a water-cooling system.  The provided models are used to mount the Water Cooling Blocks on the Peltier module. I printed them with PETG on 80% infill and 0.2 layer height. The gasket has been printed with SUNLU TPU, 100% infill. Few bolts and nuts are used to secure all the stuff together.   Here is the list of needed items to modify the cooler:Peltier  90W 40x44mm HP-127100HTS (2x): https://www.gme.cz/peltieruv-clanek-tec1-12710-200-c-vigan80mm Aluminium radiator (8x): https://www.aliexpress.com/item/1005003111461352.html?spm=a2g0o.order_list.0.0.54551802A8zTj1Water pump 9W: https://www.aliexpress.com/item/1005003203907178.html?spm=a2g0o.order_list.0.0.54551802A8zTj1G1/4 Stop Plug Fitting: https://www.aliexpress.com/item/32839077621.html?spm=a2g0o.order_list.0.0.54551802A8zTj1Water Cooling Block 40x40mm (2x): https://www.aliexpress.com/item/1005003223415808.html?spm=a2g0o.order_list.0.0.54551802A8zTj1G1/4 to 3/8 Fitting (4x): https://www.aliexpress.com/item/4001200511925.html?spm=a2g0o.order_list.0.0.54551802A8zTj1Water Reservoir: https://www.aliexpress.com/item/32985214744.html?spm=a2g0o.cart.0.0.2e743c00NkULCr&mp=1Fan 80x80x25mm 12V DC/120mA 33dB SUNON EF80251S1-1000U-A99 (8x): https://www.svetsoucastek.cz/ventilator-sunon-ef80251s1-1000u-a99-p124899/Few M4 nuts and bolts.Soft tubingZip ties / hose clamps You can use different stuff, just make sure you have enough water flow and heat dissipation via radiators. The system I had built works well and is stable. I will provide more photos and details later when I will revise the system. It working for about 6 months now and I haven't got a chance to disassemble it.
