A climatization container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing climatization containers, such as refrigerators, suffer from uneven air circulation and energy inefficiency due to fans directing air horizontally, which can lead to localized over-cooling near the fan and obstruction of airflow by products on the bottom, requiring higher energy consumption to compensate.
Innovation Solution
Positioning the fan angled relative to the vertical direction to direct air towards the top wall and using a baffle to guide air over upper shelves, with a spaced bottom shelf to allow unimpeded airflow return, enhancing circulation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the fan directs air horizontally in existing climatization containers, then the fan structure is simple and easy to manufacture, but the air circulation becomes uneven and energy consumption increases
Solution Approach 1:
The fan is repositioned from a horizontal air direction to an angled configuration that directs air towards the top wall, utilizing the vertical dimension to improve air circulation patterns. This dimensional change allows cooled air to flow over products on upper shelves first, then return along the bottom, creating more uniform cooling throughout the compartment while maintaining manufacturing simplicity.
2Productivity
If products are placed on the bottom of the compartment, then storage capacity is maximized, but airflow obstruction occurs and cooling efficiency decreases
Solution Approach 1:
The air circulation pattern is designed with different flow characteristics at different locations: cooled air from the fan flows upward and forward over products on upper shelves, while return air flows along the bottom of the compartment. This localized quality differentiation allows products on the bottom to be cooled by returning air without obstructing the primary cooling airflow path.
3Temperature
If the fan directs air towards products near the fan, then cooling intensity near the fan is high, but temperature distribution becomes uneven across the compartment
Solution Approach 1:
The fan is positioned and angled to direct cooled air toward the top wall and over products on upper shelves first, before the air descends and flows forward to cool products on lower shelves and the bottom of the compartment. This preliminary action ensures that all products receive cooling in a systematic sequence, achieving uniform temperature distribution throughout the entire compartment.
