Study on Performance of the Thermoelectric Cooling Device with Novel Subchannel Finned Heat Sink

The thermoelectric refrigeration system is an application of the Peltier effect, and good performance dependent on effective heat dissipation performance. To enhance cooling system, this paper designs a new type finned sink, which does not change overall size system. under fin tested by experiments various conditions. During experiment, wind speed, temperature hot cold side TEC, power consumption fan, other parameters were directly recorded through measuring instrument. results show that use sinks can improve COP Within scope study, thermal resistance fins be reduced 42.6%, value increased 22.8%. In addition, increasing speed further reduce temperature. research range, lowest reach ?8.25 °C, but consumed fan 166% conventional sink device.
