Cooling Bar Chamber Layout for Fast Drainage and Uniform Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling devices for rolled materials face challenges in rapid emptying of cooling medium, leading to long dripping times, uneven cooling, and inadequate self-cooling during breaks, often requiring complex and fault-prone automation and large valves.
Innovation Solution
The design features first conduit means that penetrate the wall and protrude into the lower chamber with an open end, and second conduit means that extend upward from the bottom of the lower chamber, allowing for rapid drainage and uniform cooling medium distribution, with controllable shut-off elements and venting elements to facilitate quick emptying and self-cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional cooling device design is used with cooling bars and internal distributor pipes, then cooling function is provided, but long dripping time occurs after cooling process ends
Solution Approach 1:
The cooling device is divided into two separate chambers: an upper chamber for water supply and a lower chamber for water discharge and nozzle operation. This segmentation allows independent control of water levels in each chamber, enabling rapid emptying of the lower chamber without affecting the upper chamber's water supply function.
Solution Approach 2:
A wall with openings is introduced as an intermediary structure between the upper and lower chambers. This wall mediates the water flow from the upper chamber to the lower chamber while allowing independent level control. The wall structure enables the lower chamber to be emptied rapidly through bottom outlets while the upper chamber maintains its water supply function.
2Object-affected harmful factors
If cooling medium level is maintained in conventional design, then continuous cooling is possible, but water drips onto material after cooling stops
Solution Approach 1:
The cooling device is divided into two separate chambers: an upper chamber for water supply and a lower chamber for water discharge and nozzle operation. This segmentation allows independent control of water levels in each chamber, enabling rapid emptying of the lower chamber without affecting the upper chamber's water supply function.
Solution Approach 2:
The water level in the lower chamber is dynamically controlled to be above the nozzle outlets during cooling operation and rapidly dropped below the nozzle outlets after cooling stops. This parameter change in water level position enables the system to switch between cooling mode and rapid emptying mode, preventing water dripping onto material while maintaining cooling effectiveness during operation.
3Loss of time
If rapid emptying is achieved using large valves and complex automation, then emptying time is reduced, but device complexity and fault risk increase
Solution Approach 1:
The complex valve and automation control system is completely removed from the design. Instead, the invention uses simple gravity-driven flow control through strategically positioned conduit openings and outlets. The lower chamber empties rapidly through bottom outlets without requiring any valves or automated control, achieving fault-free rapid emptying.
Solution Approach 2:
The cooling device performs self-emptying through its own structural design. The lower chamber automatically drains water through bottom outlets when the water level drops, without requiring external control systems. The system uses its own gravity and pressure differential to achieve rapid emptying, eliminating the need for complex automation.
4Manufacturing precision
If cooling bars are designed with internal distributor pipes, then cooling medium distribution is provided, but uniform cooling is difficult to achieve
Solution Approach 1:
The internal distributor pipe system is completely removed from the cooling bar design. Instead, the invention uses a lower chamber with multiple simple outlet openings positioned at the bottom. Water flows directly from the upper chamber through the wall into the lower chamber and exits through these bottom outlets, eliminating the complex internal piping while achieving uniform water distribution through proper outlet positioning.

Function Achieved in This Case
This configuration significantly reduces dripping time, ensures uniform cooling, and allows for effective self-cooling during breaks, minimizing the need for complex elements and reducing emptying time to under 1 minute, while maintaining homogeneous water distribution and protecting the cooling bars.
Implementation Method 1
first conduit means are provided which conduct the cooling medium from the upper chamber into a second, lower chamber
Implementation Method 2
second conduit means are provided which conduct the cooling medium from the lower chamber to at least one outlet opening for the cooling medium, via which the cooling medium is discharged onto the material to be cooled
