Four main performance indexes of semiconductor refrigeration chips
Refrigerating plate, performance
The four main performance parameters of semiconductor cooler refer to:
Maximum current Imax: refers to the constant hot surface temperature Th, when the load Qc is 0 Δ T reaches Δ The current value at Tmax is the maximum current value.
Maximum current Umax: refers to the constant hot surface temperature Th, when the load Qc is 0 Δ T reaches Δ The voltage value at Tmax is the maximum voltage value.
Maximum temperature difference Δ Tmax: when the heat absorption of the cold surface is 0, the temperature of the hot surface is constant. When I=Imax, the maximum temperature difference between the cold surface and the hot surface can be reached.
Maximum heat absorption QCmax: constant hot surface temperature, temperature difference between cold surface and hot surface Δ When T=0, the heat that can be absorbed by the cooling surface when I=Imax.
