0.6kWh / 5min * 60min/1h is still 7.2kW. It only needs to handle those 7.2kW of heat loss for five minutes, not continuously, but the power doesn't change.

- Xylakant 4y agoThe power doesn’t change, but you get 12 systems that each need to dissipate 600Wh instead of a single system that needs to dissipate 7200Wh. You can for example partially buffer the heat if you know that you only need to handle that load for a few minutes. It’s much harder to sustain the same energy dissipation for an hour.
- michaelt 4y agoAccording to [1] petrol cars' fan-cooled radiators can dissipate 50kW Dissipating a mere 7.2kW sounds achievable, by automotive standards? [1] https://file.scirp.org/Html/6-1520083_67628.htm https://file.scirp.org/Html/6-1520083_67628.htm
