Triple anti-supercooling safe designs
" summer sits up stone, and the autumn sits up plate." once human body loses thermal balance, it is easy for leading to hypothermia, life is caused to endanger
The disease seed of trouble is buried in danger.Therefore, anti-supercooling protection is most important.
Maximum cooling capacity limits anti-supercooling design
The present invention has done abundant research to human thermal comfort, and it is 13.8W to calculate the refrigerating capacity needed when sleep quality, is examined
Consider the heat exchange of the thermal capacity and aluminium absorber plate and air of bamboo mat, the overall refrigerating effect of TEC1-12706 semiconductor chilling plates is
14.4W~21.6W is suitable.

When thermistor temperature sensor is bad or electronic temperature controller breaks down, aluminium absorb heat plate temperature it is too low → heat transfer
The temperature difference ↑ → refrigerating capacity ↓ → aluminium heat absorption plate temperature ↑, when monolithic heat transfer temperature difference is 67K, refrigerating capacity → 0.
On the other hand, when refrigerating capacity ↑ → TEC hot-side temperatures ↑ → heat transfer temperature difference ↑ → refrigerating capacity ↓
Therefore, this programme has the anti-supercooling defencive function of self limiting.

Due to using the equidirectional superposition series connection of two pieces of TEC1-12706 semiconductor chilling plates, TEC1-12706 semiconductor refrigeratings
The cold and hot both ends maximal heat transfer temperature difference of piece is 67 DEG C × 2=134 DEG C, and the heat transfer temperature difference at hot and cold both ends ↑ → refrigerating capacity ↓, therefore
It is necessary to control the heat transfer temperature difference at the cold and hot both ends of TEC1-12706 semiconductor chilling plates.On the other hand, TEC semiconductor chilling plates heat
It holds temperature excessively high, easily damages TEC semiconductor chilling plates.For this purpose, this programme, which uses, is tightly attached to TEC1-12706 semiconductor refrigeratings
The bimetal strip thermostat (normally closed, 55 DEG C power-off) in piece hot junction realizes the hot junctions TEC overheating protection.
