Sl. No. Parameters SMMHP [6] TMMHP Remarks
1 Thermal conductivity (k) Constant Variable Rate of heat removal is increased in TMMHP.
2
Bandwidth of condensation temperature (Water, 0oincln.)
Small 33.9o - 37.5 oC Large 30.7o - 36.5 oC
Condensation takes place at higher temp. in TMMHP than in SMMHP.
3 Overall temp. difference between two ends of MHP (Water, 0oincln.) 41.2 oC 13.0oC In TMMHP is much smaller, thus enhances cyclic order and quick heat removal.
4 Temp. gradient at condenser for water Negative Positive Positivity at TMMHP improves capillary action.
5
Time reqd. to complete cycle (Water, 0oincln.)
2 min
1½ min
Because of thermal vacuum created in TMMHP.
6 h/heff (Water, 0o) 0.93 1.82 Overall h is very high at TMMHP.
7 Overall h (Water, 0oincln.) 0.46 kW/m2. oC 1.33 kW/m2. oC At TMMHP h reaches enormously high.
8 h with respect to increasing Q ~uniform increasing Mean value of h is 3.5 times higher at TMMHP than that of SMMHP.
