Cold Plates Thermal Solutions Liquid Cooling

Liquid cooling in cold plates is a natural evolution beyond air cooling. The need for improved thermal performance and environmental requirements is important driving factors.
CSI’s liquid cold plates offer a high transfer coefficient, although this depends on the specific coolant used and mode of convective heat transfer. There are many ways to accomplish liquid cooling.
Cooling Source manufactures several types of liquid-cooled heatsinks / cold plates. We use various manufacturing processes such as high precision CNC machining, extrusion, tube bending, and friction stir welding (FSW).
The FSW technology provides solid-state joints with mechanical properties like the parent materials, which results in a monolithic structure to achieve a very strong hermetic seal. Consequently, it eliminates the need to use a tube. Also, it provides greater design flexibility.
One of the most popular manufacturing methods is to machine a groove in the base and embed a tube in the flow path. Design engineers often place the tube toward the top surface. Therefore, it provides better cooling to the devices. In addition, this construction method can be cost-effective.
The heatsink / liquid cold plate can be manufactured with copper or aluminum alloy.cold plate
 We bend copper, aluminum, and stainless-steel tubes.

Some of the main benefits achieved are:
The reduction of noise, and is also more efficient. Some of the drawbacks include the risk entailed with the proximity of liquid to electronics and its cost. Liquid cold plates are more expensive than fan sinks, which require fewer components such as reservoir, pump, water blocks, hose, and heatsinks.
