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

The article addresses the problems of low linearity, poor reliability, and susceptibility to environmental and other factors in the measurement of small flow rates by liquid mass flow meters in industry and designs a refrigeration-type thermal mass flow controller without making the device large-scale. Adopting a microprocessor and pt1000 temperature sensor, the semiconductor refrigeration sheet utilizing the Peltier effect makes the temperature difference of the flowing liquid so as to measure the liquid mass flow rate by obtaining the temperature data and analyzing the data in order to achieve the function of flow rate measurement, so as to realize the purpose of flow rate measurement and control. By keeping the heating element and the measured fluid temperature difference constant after constant power work, measuring the fluid temperature after heat transfer, and finally detecting the voltage connected to the platinum resistor to react to the fluid flow. After preliminary testing in non-extreme environments, it is proved that the system has the characteristics of low cost and low power consumption, which is of reference value for the development and application of embedded systems and provides an effective method for the measurement of micro-flow liquids.
