Refrigeration Trailer Air Chute Layout to Prevent Loading Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigeration trailer air distribution chutes are prone to damage during cargo loading and unloading due to their drooping design, obstruct lighting, and require laborious and time-consuming installation, leading to increased costs and reduced efficiency.
Innovation Solution
A refrigeration trailer air distribution chute design featuring a first air director attached to the ceiling along two lines of attachment and a second air director attached along a single line, allowing the chute to hang parallel to the side wall, minimizing damage risk and simplifying installation by eliminating the need for guide lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air distribution chute is designed to extend along the center of the ceiling with a drooping configuration, then cooled air flow from the refrigeration unit to the rear of the trailer is ensured, but the chute becomes prone to damage during cargo loading and unloading operations
Solution Approach 1:
The air distribution chute is divided into multiple segments or sections that can be independently positioned. This allows the chute to be configured in a way that reduces exposure to damage during cargo operations while maintaining air flow functionality.
Solution Approach 2:
The chute design transitions from a traditional center-ceiling extension to a configuration that utilizes side wall attachment points. This dimensional change repositions the chute away from the high-traffic cargo loading zone, reducing damage risk while maintaining air distribution effectiveness.
2Manufacturing precision
If traditional air distribution chutes are installed using guide lines and multiple attachment points, then proper air flow positioning is achieved, but installation becomes laborious and time-consuming
Solution Approach 1:
The chute is pre-configured with attachment features and positioning elements during manufacturing. This preliminary preparation eliminates the need for complex on-site measurements and guide line installations, allowing for rapid deployment while maintaining positioning accuracy.
Solution Approach 2:
The chute design incorporates self-aligning features and self-supporting structures that automatically position the component correctly during installation. This self-service capability eliminates the need for external guide lines and reduces the skill level and time required for installation.
3Temperature
If the air distribution chute is positioned close to the ceiling for effective air flow distribution, then cooling efficiency is improved, but the chute obstructs ceiling lighting and increases heat transfer to the cargo area
Solution Approach 1:
The chute is repositioned from a center-ceiling location to side wall attachment points, utilizing the vertical space along the side walls. This dimensional relocation maintains proximity to the cooled air source while clearing the ceiling lighting path and reducing heat transfer exposure to the cargo area.
Solution Approach 2:
The chute is extracted from the central ceiling position and relocated to side wall positions. This separation removes the obstructing element from the lighting path and reduces its exposure to ceiling-generated heat while preserving its air distribution function.
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
The design reduces the likelihood of chute damage, shortens installation time, minimizes ceiling coverage, and reduces heat transfer, thereby enhancing the chute's durability and operational efficiency.
Implementation Method 1
the refrigeration unit draws air from the bottom of the refrigeration trailer into the refrigeration unit through the air intake, cools the air via one of a variety of different conventional manners, and expels the cooled air into the upper portion of the refrigeration trailer through the air outlet
Implementation Method 2
after the chute body is installed, gravity causes the center of the chute body to hang down or droop about 6 to 8 inches (15.24 to 20.32 centimeters) below the ceiling of the refrigeration trailer along the entire length of the chute body

AI summary
Various embodiments of the present disclosure provide a refrigeration trailer air distribution chute. The chute includes a first air director attachable to a ceiling of a refrigeration trailer spanning a refrigeration unit and a side wall of the trailer, and a second air director attachable to and extending along the ceiling proximate the side wall to the rear of the trailer. The first air director is attachable to the ceiling along two lines of attachment, causing the first air director to have a cross section of a first shape regardless of whether the chute is in an unexpanded or an expanded state. The second air director is attachable to the ceiling along one line of attachment, causing the second air director to have a cross section of a second shape when the chute is in the unexpanded state and a third shape when the chute is in the expanded state.
