Cooling Unit Layout to Preserve Airflow Around Integrated Controls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling devices for heating element storage boxes experience a decrease in air flow rate and cooling capacity due to the installation of control devices, which can lead to inefficient heat exchange and reduced performance.
Innovation Solution
The cooling device incorporates a heat exchanger with an indoor air channel, outdoor air channel, indoor and outdoor blowers, a control device, and a control device accommodating unit, where the blowers' axial direction and air suction direction are parallel, and the heat exchanger is positioned downstream of both blowers, with the control device unit strategically placed to minimize airflow obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the control device is installed in the section where the fan is disposed, then the control function is integrated, but the air flow rate is lowered and cooling capacity is reduced
Solution Approach 1:
The cooling device is divided into separate functional sections: the fan section for air circulation and the control device section for operational control. This segmentation allows each component to perform its function optimally without interfering with the other, specifically preventing the control device from obstructing airflow paths.
Solution Approach 2:
A dedicated control device accommodating section acts as an intermediary space that houses the control device without allowing it to interfere with the fan's airflow. This intermediary section serves as a buffer zone that isolates the control device from the airflow path while maintaining system integration.
2Device complexity
If the control device is installed in the section where the fan is disposed, then the control function is integrated, but the air blowing state to the heat transfer plate is biased
Solution Approach 1:
The cooling device is divided into separate functional sections: the fan section for air circulation and the control device section for operational control. This segmentation allows each component to perform its function optimally without interfering with the other, specifically preventing the control device from obstructing airflow paths.

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 configuration maintains a higher air flow rate and cooling capacity by reducing pressure loss and ensuring smooth air passage through the heat exchanger, effectively addressing the issues caused by control device placement in conventional systems.
Implementation Method 1
By such forced convection, heat is exchanged through barrier walls of heat transfer plate 110, and the air in control panel 100 is cooled.
Implementation Method 2
the heat exchanger exchanges sensible heat between the air in the indoor air channel and the air in the outdoor air channel

AI summary
A control device accommodating unit (15) is provided in a section (50) accommodating an indoor air blower (7) adjacently to an indoor air flow-in port (16), and an impeller (7c) of the indoor air blower (7) is sequentially opposite to the indoor air flow-in port (16) and the control device accommodating unit (15) by rotation of the impeller (7c), and a space (51) is formed between the indoor air flow-in port (16) and the control device accommodating unit (15). In this configuration, it is possible to obtain a cooling device decreased in drop of air flow rate and drop of cooling performance due to mounting a control device (14).
