一种冰箱用一体式冷凝风道结构设计与应用研究

Study on Design and Application of an Integrated Condensing Air Duct Structure for Refrigerator

通过分析现有大容积风冷冰箱冷凝模块的设计现状,从风扇支架、冷凝风道、冷凝器以及固定方式等方面进行技术方案的优化改进,设计出一种冰箱用一体式冷凝风道结构。结果表明,一体式冷凝风道结构是集风扇支架、冷凝风道以及冷凝器安装结构为一体的创新设计,微通道冷凝器边板设计有与一体式冷凝风道对应的固定孔,可以确保冷凝风扇扰流的冷凝风全部扫掠过微通道冷凝器的表面,进一步强化换热效果。该种一体式冷凝风道结构具有结构整体尺寸小,安装方便,成本低等优点,可以满足更宽容积段的大容积风冷冰箱的冷凝模块设计要求。

Through analysis of the current situation on the air cooled refrigerator with large volume, an integrated condensing duct structure for refrigerator is designed by the improvement of a fan bracket, condensing duct, con- denser and fixed mode. The results show that an integrated condensing duct structure is an innovative design, which includes fan bracket, condensing ducts and Condenser mounting structure. A fixed hole in the side plate of the micro- channel condenser is corresponding to the integral condensation air duct＇ s hole, which can ensure that the condens- ing air of the condensing fan swept over the surface of the micro-channel condenser, and the heat transfer effect is further enhanced. The structure of the integral condensation air duct has the advantages of small size, convenient in- stallation, low cost etc, and can meet the design requirements of the condensing module for the air cooling refrigera- tor with wider volume.
