Description

technical field [0001] The invention relates to the technical field of thermoelectric conversion devices, in particular to a heat transfer device based on a semiconductor wafer and equipment using the device. Background technique [0002] The unsatisfactory performance of current thermoelectric materials is one of the main reasons for the low efficiency of semiconductor thermoelectric power generation. The main performance parameter to measure thermoelectric materials is the dimensionless figure of merit ZT of thermoelectric materials: [0003] [0004] In the formula, α is the Seebeck coefficient; σ is the electrical conductivity; λ is the thermal conductivity; T is the absolute temperature. The higher the dimensionless figure of merit ZT of a thermoelectric material, the better its thermoelectric performance and the higher its thermoelectric conversion efficiency. Through the above formula, we know that the higher the Seebeck coefficient and electrical conductivity, th...
