Delivering Efficient and Uniform
Cooling for Every Heat Source,
Eliminating Heat-Induced Performance
Loss and Output Limitations
High-Performance Cold Plate
-
- Want to reduce power consumption.
- Cooling capacity is limited by the performance of the pump or external chiller.
- Want to minimize the temperature difference.
- Temperature difference during cooling directly leads to performance variation among heat-generating components. Manufacturing quality becomes uneven.
- Want to entrust everything from design to production.
- Although target requirements are defined, the optimal flow path of coolant cannot be identified. A supplier cannot support a wide production range, from small-lot to mass production.

What is a Cold Plate?
A cold plate is a thermal management device that transfers heat from a heat source to coolant flowing through internal channels, enabling heat dissipation at a remote location.
Rather than simply dissipating heat at the source, a cold plate carries heat away from the heat-generating area, providing greater flexibility in thermal design even in space-constrained environments.
It is ideal for high heat-density applications and equipment that require stable temperature control with minimal temperature variation.

Maruyasu's High-Performance Liquid-Cold Plate
A high-performance liquid-cold plate is more than just a cooling component - it is a critical element of thermal design that directly impacts equipment performance and service life.
Leveraging heat transfer and fluid flow expertise cultivated through automotive heat exchanger development, Maruyasu Industries uses thermal-fluid analysis to visualize heat and flow behavior, optimizing channel design, geometry, and joining technologies from concept development through mass production.
Even when multiple heat sources with different heat loads are integrated into a single unit, we design heat diffusion and coolant flow to minimize temperature variations and ensure uniform cooling. This contributes to greater temperature stability and improved performance across the entire system.
Five Features of the
High-Performance
Liquid-Cold Plate
01Highly Efficient Cooling
POINT.01
Optimized coolant flow paths reduce pressure loss, contributing to smaller pump requirements and lower power consumption. 
POINT.02
By controlling flow velocity and optimizing flow channels, cooling can be concentrated where it is needed most. 
02Uniform Cooling
Optimized flow channels enable uniform cooling across heat-generating components. Even when multiple heat sources with different heat loads are integrated into a single system, temperature variations can be minimized through optimized flow channel design and precise flow velocity control.
03Flexible Coolant Flow Channel Design
-
Compared with FSW (Friction Stir Welding), brazed construction offers greater design flexibility, enabling high-density flow channel layouts.
Effects
・Intensively cool areas with high heat generation.
・Maximizes utilization of the entire cold plate surface.
・Minimizes temperature differences across the device.
