Custom Aluminum Liquid Cold Plate for High-Power Industrial Equipment Thermal Management
Project Overview
Application: Industrial Power Equipment Cooling
Product: Custom Liquid Cold Plate
Customer Location: USA
Material: Aluminum 6061
Manufacturing Process: CNC Machining + Precision Sealing + Performance Testing
A US industrial power equipment manufacturer required a customized liquid cooling solution for its high-power electrical modules.
During continuous high-load operation, the customer’s original cooling design experienced uneven temperature distribution and localized overheating in critical heat-generating areas.
Because the equipment structure had limited installation space, the customer needed a compact liquid cold plate that could improve thermal performance without changing the existing mechanical design.
Jindu Tech developed a customized aluminum liquid cold plate with optimized internal cooling channels, precision machining, and reliability testing to support the customer’s transition from prototype validation to mass production.
Cooling Challenge: Improving Thermal Performance Within Limited Space
The customer’s equipment generated significant heat during operation, creating several thermal management challenges:
• Localized hotspots appeared during high-load operation.
• The existing cooling solution could not provide sufficient temperature uniformity.
• Available installation space prevented increasing the overall cold plate size.
• Long-term operation required reliable sealing performance to avoid coolant leakage.
• The contact surface required strict flatness control.
The challenge was to develop a compact liquid cold plate that balanced cooling performance, structural requirements, manufacturing accuracy, and long-term reliability.
Customer Requirements
The customer required:
• Aluminum 6061 liquid cold plate structure
• Customized internal coolant channel layout
• Compact design compatible with existing equipment
• High flatness contact surface
• Leak-proof cooling structure
• Prototype testing before mass production
Jindu Tech Engineering Solution
Optimized Internal Flow Channel Design
Jindu Tech’s engineering team analyzed the customer’s heat distribution requirements and redesigned the internal cooling channel structure.
The optimized channel layout guided coolant through the main heat-generating areas, improving heat transfer efficiency and reducing temperature differences across the cooling surface.
Precision CNC Machined Cold Plate Manufacturing
The liquid cold plate was manufactured using CNC machining to achieve accurate dimensions and reliable surface quality.
The machining process ensured accurate channel geometry, stable product dimensions, proper installation compatibility, and smooth sealing surface preparation.
Leak Prevention and Reliability Testing
Since liquid cooling systems require long-term reliability, Jindu Tech performed multiple inspection procedures before shipment.
Testing included:
• Dimension inspection
• Flatness inspection
• Air leakage testing
• Pressure testing
• Customer equipment testing
Prototype Validation and Mass Production
After prototype completion, Jindu Tech delivered samples for customer equipment testing.
The customer verified that the customized liquid cold plate met the required installation and cooling requirements.
Following successful validation, the project moved from prototype development into volume production.
Based on the successful cooperation, Jindu Tech continued supporting the customer with additional liquid cold plate designs for new applications.
