Built-In Refrigerator Airflow Guide to Prevent Heat Recirculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Built-in refrigerators face inefficiencies in heat transfer due to air circulation phenomena where discharged heat is re-suctioned into the machine room, reducing heat transfer efficiency.
Innovation Solution
The implementation of an airflow guide member that partitions the machine room into upper and lower sides, guiding external air suction and heat-exchanged air discharge to prevent mixing and enhance heat radiation, including a suction duct at the lower side and a discharge passage guide to direct air upward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If air is suctioned through the lower side and discharged through the rear side of the refrigerator body, then heat exchange in the machine room is performed, but discharged heat is re-suctioned into the machine room reducing heat transfer efficiency
Solution Approach 1:
The machine room is divided into an upper portion and a lower portion using a partition wall. The lower portion contains the suction passage for introducing external air, while the upper portion contains the discharge passage for exhausting heat-exchanged air. This segmentation prevents discharged air from being re-suctioned, thereby improving heat transfer efficiency and resolving the technical contradiction.
2Volume of moving object
If the refrigerator body is installed in a built-in cabinet, then space is saved and appearance is improved, but heat radiation in the machine room is hindered
Solution Approach 1:
The suction passage is configured to extend downward from the lower side of the refrigerator body, and the discharge passage is configured to extend upward from the rear side. This vertical dimensionality change allows heat-exchanged air to be discharged upward away from the suction inlet, preventing recirculation and improving heat radiation efficiency while maintaining compact built-in installation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively prevents air recirculation, improving heat transfer efficiency by ensuring external air is not reintroduced into the machine room, thereby enhancing the heat radiation process.
Implementation Method 1
an airflow guide member installed between the blower fan and the condenser, for guiding suction of an external air toward the other side of the machine room and guiding a discharge of heat-exchanged air in the other side of the machine room
Implementation Method 2
a blower fan installed at the other side of the machine room
Implementation Method 3
a condenser and a blower fan installed at the other side of the machine room
