Description
技术领域technical field

背景技术Background technique
现有冰箱的冷凝风道组件大多用轴流风扇，从后盖板吸风，由于轴流风扇的轴进轴出的进风特点，导致整个冷凝风道的进风风速不均匀、风阻较大、风量较小，导致冷凝器散热性能较差；由于轴流风扇进风口的约束，使得轴流风扇必须放置在压缩机仓中段附近，增大了压缩机仓的体积，限制了结构的设计；同时由于后盖板进风口没有防尘措施，导致灰尘覆盖在冷凝器及风扇叶片上，增大了风扇风阻，降低了冷凝器的换热性能，增大耗电量。Most of the condensing air duct components of the existing refrigerators use axial flow fans to suck air from the rear cover. Due to the air inlet characteristics of the axial fan shaft in and out, the air inlet wind speed of the entire condensing air duct is uneven and the wind resistance is large. 1. The air volume is small, resulting in poor heat dissipation performance of the condenser; due to the restriction of the air inlet of the axial flow fan, the axial flow fan must be placed near the middle section of the compressor compartment, which increases the volume of the compressor compartment and limits the structural design; At the same time, because there is no dust-proof measure for the air inlet of the rear cover, dust covers the condenser and fan blades, which increases the wind resistance of the fan, reduces the heat transfer performance of the condenser, and increases power consumption.
