Solution Overview
Problem
Existing heat dissipation structures in cabinets increase fan power consumption and operating costs due to high flow resistance caused by densified thermally conductive plates, which compromises the balance between heat dissipation area and airflow efficiency.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the thermally conductive plate is densified to increase heat dissipation area, then heat dissipation area is increased, but flow resistance rapidly increases
Solution Approach 1:
The thermally conductive plate is designed with a wrinkled structure featuring continuous grooves and protrusions, transforming a flat surface into a three-dimensional curved structure. This curvature increases the heat dissipation area without proportionally increasing flow resistance, as the curved surfaces guide airflow more effectively than dense flat plates would
Solution Approach 2:
The invention transitions from a two-dimensional flat plate to a three-dimensional wrinkled structure with continuous grooves and protrusions. This dimensional transformation allows the plate to achieve greater surface area for heat dissipation while maintaining airflow passages that prevent excessive flow resistance
2Area of stationary object
If the thermally conductive plate is densified to increase heat dissipation area, then heat dissipation area is increased, but operating costs rise
Solution Approach 1:
The wrinkled structure with continuous grooves and protrusions creates a curved surface that maximizes heat dissipation area. The curvature is optimized to maintain airflow efficiency, thereby reducing the energy required for cooling and lowering operating costs while achieving enhanced heat dissipation
3Area of stationary object
If the thermally conductive plate is densified to increase heat dissipation area, then heat dissipation area is increased, but flow resistance rapidly increases
Solution Approach 1:
The continuous grooves and protrusions create a wrinkled surface with optimized curvature that increases heat dissipation area while maintaining airflow efficiency. The curved geometry guides air flow smoothly across the surface, preventing the rapid increase in flow resistance that would occur with densified flat plate structures

Implementation Method 1
a thermally conductive plate is disposed between the inner wall and the outer wall... Air in the internal circulation air duct and air in the external circulation air duct exchange heat by using the thermally conductive plate
Implementation Method 2
a flow disturbing panel is disposed in the internal cavity or/and the external cavity, and is configured to convert the internal circulation air flow or/and the external circulation air flow into a vortex flow
Implementation Method 3
Space between the outer wall and the thermally conductive plate is connected to the outside, and can cooperate with a fan or another flow guiding apparatus, to form an external circulation air duct, for exchanging air with the outside

AI summary
A cabinet (10) is provided, where: an inner wall (11) and an outer wall (13) are disposed in the cabinet (10), and a cavity is formed between the inner wall (11) and the outer wall (13); a thermally conductive plate (15) is further disposed in the cabinet (10), where the thermally conductive plate (15) is disposed between the inner wall (11) and the outer wall (13) and divides the cavity into an internal cavity (110) and an external cavity (130) that are mutually isolated, the internal cavity (110) and an inside of the cabinet (10) are interconnected, to form an internal circulation air flow, and the external cavity (130) and an outside of the cabinet (10) are interconnected, to form an external circulation air flow; a flow disturbing panel (17) is further disposed in the cabinet (10), where the flow disturbing panel (17) is disposed in the internal cavity (110) or/and the external cavity (130), and is configured to convert the internal circulation air flow or/and the external circulation air flow into a vortex flow. In the cabinet, by disposing the thermally conductive plate and the flow disturbing panel, a heat exchanging capability of the thermally conductive plate can be greatly improved while slightly increasing flow resistance to an air flow, thereby improving overall heat dissipation efficiency of the cabinet and ensuring air-tightness of the cabinet.
