Solution Overview
Problem
Conventional refrigeration devices in edge node equipment rooms face challenges in adapting to different types of cabinets, such as top-exhaust and side-exhaust cabinets, due to limited adaptability, which affects the normal operation of these rooms.
Innovation Solution
A refrigeration device with an indoor unit featuring adjustable ventilation ducts and a baffle assembly that can change air intake directions, allowing it to accommodate both top-exhaust and side-exhaust cabinets by separating or combining ventilation ducts and adjusting fan directions, thereby enhancing its universality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a refrigeration device uses a fixed ventilation duct configuration, then the device structure is simple, but the adaptability to different cabinet types (top-exhaust or side-exhaust) is poor
Solution Approach 1:
The ventilation duct configuration is made adjustable through a baffle assembly that can change the air intake direction between first and second ventilation ducts. This dynamic adjustment allows the refrigeration device to adapt to different cabinet types (top-exhaust or side-exhaust) without requiring multiple fixed configurations, resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If the refrigeration device uses separate ventilation ducts for different cabinet types, then the adaptability improves, but the device complexity and space occupation increase
Solution Approach 1:
The first and second ventilation ducts are merged into a single integrated structure with a shared air outlet. The baffle assembly enables these ducts to cooperate and switch between different ventilation modes (side-supply side-return or top-supply top-return) without occupying additional space. This combining approach maintains adaptability while avoiding increased space occupation.
3Adaptability or versatility
If the refrigeration device is designed for a specific cabinet type, then the device structure is simplified, but the universality across different equipment room configurations is reduced
Solution Approach 1:
The refrigeration device achieves multi-functionality through the baffle assembly that can adjust the air intake direction of the ventilation ducts. This single device can serve both top-exhaust and side-exhaust cabinet types by switching between different ventilation modes, eliminating the need for multiple specialized devices and enhancing universality without excessive complexity.

AI summary
A refrigeration device includes an indoor unit and an outdoor unit. The indoor unit is used for heat exchange with air inside an equipment room. To adapt to different cabinets, one or more ventilation ducts of the indoor unit include a plurality of channels, and a baffle assembly is disposed in the indoor unit. An air flow direction in the ventilation duct is changed using the baffle assembly, and the baffle assembly is adjusted to block different positions to apply the refrigeration device to different types of cabinets.
