A Preliminary Study of Self-Exciting Mode Oscillating-Flow Heat Pipe Used in the Heat Recovery of Wood Drying

Abstract:

First building up the test bed of heat recovery unit which made use of Self-Exciting Mode Oscillating-Flow Heat Pipe heat exchanger, simulated the conventional wood drying chamber exhaust conditions, this paper compared and analyzed the different heat recovery efficiency of this heat exchanger under different operating modes. The results showed that: when the air flow and temperature at the hot end kept steady, the heat recovery efficiency increased as the relative humidity increasing; while the air flow and relative humidity at the hot end remained stable, the heat recovery efficiency decreased along with the temperature increasing; the hot end temperature reached the top on the dew point. The average heat recovery efficiency of Self-Exciting Mode Oscillating-Flow Heat Pipe heat exchanger was about 15%.
