Peltier rack AC

The system is designed to cool a small 19" server rack where traditional cooling methods are impractical. In my case, it’s for a home lab setup in a 3m² storage room with forced exhaust only. A cooling block beneath the rack channels inlet airflow before it passes through the rack. Two 120mm PWM fans mounted on the top drive airflow, while a heat diffuser, consisting of a 240mm radiator with two 120mm PWM fans, is positioned outside the room to disperse heat. The system uses water as the coolant.

System Components:
- Cooling Block: Includes 8 Peltier elements, aluminum heatsink, and water blocks (1 block for 2 elements).
- Rack Fans: 120mm PWM fans with controller, mounted on the rack's top cover.
- Heat Diffuser: 240mm radiator with 2x120mm PWM fans and controller.
- System Controller: STM-based unit for monitoring performance, managing operations, and providing an interface.

Features

Rack fans RPM depends on outlet airflow temperature
Heat Diffuser fans RPM depends on outlet airflow temperature
Cooling block temperature is 5C above dev point
Gradual cooling initiation
All components are communicating with modbus protocol via RS485 bus
