Liquid cold plates can be manufactured with copper or aluminum alloy.
We bend copper, aluminum, and stainless-steel tubes.

CSI’s cold plates offer a high transfer coefficient, although this depends on the specific coolant used and the mode of convective heat transfer. There are many ways to accomplish liquid cooling. We manufacture several types of 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, resulting in a monolithic structure to achieve a solid airtight 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 line toward the top surface. Therefore, it provides better cooling to the devices. In addition, this construction method can be cost-effective.
 

Liquid cold plates are heatsinks that use liquid as a cooling medium to dissipate heat from electronic components. Cooling Source manufactures cold plates made of copper or aluminum. In addition, have channels or tubes that allow the liquid to flow through them.

The liquid is usually water, or a water-based coolant circulated through the cold plate using a pump. As the fluid flows through the channels, it absorbs heat from the electronic components. Then it carries it away from the cold plate.

Water Cold Plates

Water cold plate heatsinks, also known as liquid cold plate heatsinks, are a type of cooling solution that utilizes water or another liquid to dissipate heat from electronic components. On the other hand, traditional heatsinks are typically made of metal, such as aluminum or copper, and rely on passive air cooling.

Copper Cold Plates

Deionized Water Cold Plates

Deionized water cold plate heatsinks are a type of cooling solution commonly used in various electronic devices to dissipate heat generated by components such as CPUs, GPUs, or power modules. They utilize a cold plate, which is a metal plate in direct contact with the heat-generating component, and deionized water as the cooling medium.

Dielectric fluids Cold Plates

Dielectric fluid-based cold plate heatsinks, also known as liquid cooling systems or immersion cooling, have gained popularity in recent years for their ability to efficiently dissipate heat from electronic components. Let’s explore the difference between dielectric fluids and traditional air-based heatsinks, as well as their benefits and reliability.

Water and ethylene glycol (EG) Cold Plates

Water and ethylene glycol (also known as antifreeze) are both commonly used as coolants in cold plate heatsinks.

Aluminum Cold Plates

Aluminum cold plate heatsinks are a type of cooling solution commonly used in electronic devices to dissipate heat generated by components such as CPUs, GPUs, or power electronics. The primary purpose of a cold plate heatsink is to transfer heat away from the source and dissipate it into the surrounding environment.

Polymer Cold Plates

Polymer-based cold plate heatsinks are a type of heatsink that utilize polymer materials, such as thermoplastics or thermosetting resins, for their construction. They are an alternative to traditional metal-based heatsinks, which are typically made from materials like aluminum or copper.
