The invention discloses a semiconductor refrigeration device for flame soot particle collection. The semiconductor refrigeration device comprises a semiconductor refrigeration sheet, a wing plate type radiator, a phase change heat dissipation structure, a sunflower radiator, a lower shell and a thermal column structure. The heat dissipation area of the semiconductor refrigeration device is increased through the wing plate type radiator, and heat is further dissipated through the phase change heat dissipation structure and the heat column structure. According to the semiconductor refrigeration device, the semiconductor refrigeration sheet, phase change structure heat dissipation and heat column structure heat dissipation are combined, and efficient heat dissipation of the semiconductor refrigeration device is achieved by combining the advantages that the semiconductor refrigeration sheet is high in refrigeration capacity and the phase change material has great latent heat of phase change and the like. The whole semiconductor refrigeration device is arranged above the glass sheet, and the temperature conducting film can be correspondingly cut according to the actual size of the glass sheet. In addition, the refrigeration power can be controlled by adjusting the voltage and the current of the semiconductor refrigeration sheet, so that the temperature is adjusted.
Description
technical field [0001] The invention belongs to the field of semiconductor refrigeration, and relates to a semiconductor refrigeration control method for collecting flame soot particles, in particular to a semiconductor refrigeration device for collecting flame soot particles. Background technique [0002] Soot particles are produced when gaseous or liquid hydrocarbons undergo incomplete reactions (such as a series of complex chemical and physical actions such as combustion or pyrolysis). Due to the adverse effects of atmospheric soot particles on the global climate and human health, more and more researchers have put their interest and focus on the study of soot particles. However, in the process of collecting soot particles, the cooling temperature is difficult to adjust and the cooling efficiency is low. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a semiconductor refrigeration device for the collection of flame soot particles, w...
