Solution Overview
Problem
Existing ventilation and air conditioning systems face challenges in efficiently dissipating high thermal loads with limited primary air, often resulting in undesirably high air velocities near the device.
Innovation Solution
The air inlet opens into a distribution chamber divided by an inner wall with adjustable blow-out openings, allowing primary air to flow into either one or two distribution areas, enhancing secondary air induction through a heat exchanger, and featuring a self-regulating flap or motor-driven actuating device to optimize air flow and thermal output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the supply of primary air is restricted to avoid high air velocities, then air velocity near the device is reduced, but thermal load dissipation capability is limited
Solution Approach 1:
The distribution chamber is divided into multiple distribution areas by inner walls with adjustable openings. This segmentation allows primary air to be distributed through multiple pathways, enabling better control of air flow patterns and velocities while maintaining effective thermal load dissipation through optimized induction of secondary air.
Solution Approach 2:
Adjusting devices are provided for the openings in the inner walls, allowing dynamic adjustment of the air flow distribution. This enables the system to adapt to different thermal load conditions and optimize the balance between air velocity control and thermal dissipation performance.
2Productivity
If a single distribution area is used, then device structure is simple, but induction efficiency and thermal output are limited
Solution Approach 1:
The distribution chamber is segmented into multiple distribution areas separated by inner walls with openings. This segmentation increases the surface area for primary air distribution and enhances the induction of secondary air through the heat exchanger, thereby improving thermal output without excessive complexity.
Solution Approach 2:
The multiple distribution areas serve multiple functions: they distribute primary air throughout the induction area, control air flow patterns, and enhance secondary air induction. This multi-functionality achieves higher induction efficiency while keeping the overall device structure integrated and manageable.
3Adaptability or versatility
If primary air flows through a single path, then air flow control is simple, but performance range is limited
Solution Approach 1:
Adjusting devices are provided for the openings in the inner walls, enabling dynamic control of air flow distribution. This allows the system to adapt to different performance requirements by adjusting the openings, expanding the performance range while maintaining a relatively simple underlying structure.
Solution Approach 2:
The adjusting devices enable change in the flow cross-section areas of the distribution areas by opening or closing the openings in the inner walls. This parameter adjustment capability expands the performance range, allowing the device to operate effectively under different thermal load conditions and air flow requirements.

Function Achieved in This Case
This configuration achieves higher thermal outputs and expanded performance range with reduced air velocities, allowing for comfortable operation near the device by optimizing air flow and induction efficiency.
Implementation Method 1
The primary air flows through the air inlet into the induction area. The resulting pressure drop compared to the ambient pressure ensures that secondary air is induced via the heat exchanger.
Implementation Method 2
secondary air is induced via at least one of the heat exchangers by the primary air exiting the air inlet into the induction area
Implementation Method 3
at least one heat exchanger, so that secondary air is induced via at least one of the heat exchangers by the primary air exiting the air inlet into the induction area
