Semiconductor Refrigeration Review

Semiconductor refrigeration is mainly Peltier effect in the application of the refrigeration,The main advantages of semiconductor refrigeration:refrigeration fast,simple operation,high reliability,easy to implement high-precision temperature control,no pollution.especially in the refrigeration quantity of small,and the miniaturization of the device of the occasion.At present,widely used in national defense,scientific research,industry and agriculture,meteorological,medical and health fields.mainly for instrumentation,electronic components,drugs,vaccines and other cooling,heating and constant temperature,its scope of application seeped to each industry.In this paper,semiconductor refrigeration and mechanical refrigeration comparison illustrates the advantages and characteristics of semiconductor refrigeration.For the characteristic and application of semiconductor refrigeration,through the study of literature at home and abroad,from the impact of the efficiency of semiconductor refrigeration major aspects:theory,material,structure,mode of heat transfer are reviewed in four areas,From which summarizes the thermoelectric research focus and achievements,summarize the current problems existing in the research of semiconductor refrigeration,Put forward the main factors affecting the semiconductor refrigeration,namely:high merit factor of materials,complex multi-parameter conditions and hot and cold side heat dissipation and design.for future in-depth study of semiconductor refrigeration provided for reference the research direction and method.
