Abstract

본 발명은 냉동고의 냉기류 순환구조에 관한 것으로, 특히 흡음효과가 우수한 흡음재로서 굴절형의 기류유도통을 별도 성형하여 증발기 하측에 위치되는 기류순환덕트의 후방에 부가설치하여, 순환기류가 기류유도통을 통해 저항에 의한 유동손실이 거의 없이 증발기측으로 유도순환되도록 하는 간단한 방안을 제공함으로서, 냉기류 순환시의 순환저항 및 그에 따른 기류유동 손실을 최소화시켜 주면서 냉각장치의 작동부하 최소화 효과 및 그에 따른 냉각장치의 가동효율을 중대효과를 공히 얻을 수 있도록 하고, 흡음재로 이루어진 기류 유도통을 통해 기류순환시의 유동소음을 최소화 효과가 수반되도록 함은 물론, 그에 따른 제품신뢰도 향상효과까지 공히 기대할 수 있도록한데 그 특징이 있다.The present invention relates to the cold air flow circulation structure of the freezer, and in particular, as a sound absorbing material with excellent sound absorption effect, by separately forming a refractory air flow guide tube and additionally installed at the rear of the air flow circulation duct located under the evaporator, By providing a simple way to induce circulation to the evaporator with almost no flow loss due to the resistance, while minimizing the circulation resistance and the air flow flow loss during cold air circulation, the effect of minimizing the operating load of the cooling device and the cooling device accordingly Its operation efficiency can be obtained at the same time, and it is possible to expect the effect of minimizing the flow noise during the circulation of the airflow through the airflow induction tube made of sound-absorbing material as well as improving the reliability of the product. There is a characteristic.
