According to the low-thermal-resistance natural convection radiator for the semiconductor refrigerator, the effective heat radiating area of the low-thermal-resistance natural convection radiator is large, the heat transfer capacity of a bottom layer heat transfer technology is high, and therefore the heat radiating capacity is high, and the refrigeration efficiency of the system can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of radiators, and in particular relates to a natural convection radiator for semiconductor refrigerators with low thermal resistance. Background technique [0002] The semiconductor refrigerator is based on the "Peltier effect" for refrigeration. It has the advantages of simple structure and reliable performance. It has high cost performance in the application scenario of small cooling capacity. Excellent cooling method. [0003] Semiconductor refrigerators generate large amounts of heat while cooling, and effective thermal control is required to ensure cooling efficiency. However, hotels, hospitals and other environments need to achieve good silence, so natural convection cooling mode is required. [0004] The heat dissipation capacity of the natural convection radiator uses the system thermal resistance R = (t w -t 0 ) / Q characterization, defined as the temperature difference between the heat source in...
