Résumé

In this paper, the V-type slit nozzle in an impact type quick freezer is selected as the research object. The effects of five different nozzle structures on the heat transfer characteristics and nonuniformity of steel band surface in the direction of quick-freezing width in the quick-freezing machine are compared. The results shows that: compared with other nozzle structures, V-type slit nozzle can make the surface of steel band have larger heat transfer coefficient and surface uniformity; the existence of V-type diversion groove and nozzle outlet have an important influence on the heat transfer intensity of steel band surface. In summary, choosing the appropriate nozzle structure will effectively improve the heat transfer characteristics of steel band surface.The research provides the theoretical basis for the optimization design of the flow field of the impact freezer.
