What is a Liquid Cooling Plate?

A liquid cooling plate is the core heat exchange component of a liquid cooling system, consisting of a copper or aluminum substrate with internal microchannels. It works by circulating a coolant (such as water or a glycol solution) within these channels, absorbing heat generated by the chip (such as a CPU or GPU) (a single chip can support up to 1000W of power), and then transferring the heat to the external environment through a coolant distribution unit. Because the liquid cooling plate is in direct contact with the heat source, its thermal resistance can be as low as 0.02–0.05°C/W.

Liquid Cooling Plate Types and Technologies

The performance requirements of liquid cooling plates typically determine the choice of cooling plate manufacturing process and design, which in turn affects cost. Generally, higher performance cold plates result in higher costs. The main types of cold plates include pressure tube cold plates (also known as high-contact cold plates), gun-drilled cold plates, channel cold plates, and brazed cold plates. Channel shapes in cold plates can be manufactured through CNC machining, extrusion molding, and friction welding. Depending on the welding method, cold plate processing channels can be categorized into vacuum brazing, friction stir welding, etc. The fins within the channels can also be classified into various types based on the processing technology, such as profile fins, scraped fins, and welded fins.

Liquid Cooling Plate Manufacturing Process

The manufacturing process is the bridge between design and reality, directly affecting product performance, consistency, and cost. Various manufacturing processes are applicable to the production of liquid cooling plates. Currently, the mainstream processes are CNC machining and brazing.

placeholder

CNC Machining

Computer Numerical Control machining. This involves using high-precision cutting tools to carve the heat sink from a solid billet. It is typically reserved for high-precision prototypes or extremely complex geometries where tooling for other methods is not feasible.
placeholder

Brazing

The substrate and the cover plate are stacked with a filler metal in between an alloy sheet or coating with a lower melting point than the base materials. The assembly is then heated in a vacuum or protective atmosphere furnace until the filler melts, filling the gaps via capillary action to create a metallurgical bond. This process allows for the creation of highly complex internal channels, offers good thermal performance, and is ideally suited for large-scale production.
placeholder

Friction Stir Welding (FSW)

A high-speed rotating stir pin is inserted into the joint between the plates to be welded, generating frictional heat that softens the material. Through the mechanical action of the stir pin, a solid-state bond is achieved. This process produces high-strength welds with minimal defects and deformation, avoiding common fusion welding issues such as porosity or cracking. No filler material is required.
placeholder

Metal 3D Printing

Metal powders are used to print integrated cold plates with complex internal channels layer by layer using techniques such as Selective Laser Melting (SLM). This approach offers unparalleled design freedom, enabling the creation of biomimetic or irregular flow channels that are impossible to manufacture with traditional methods, thereby pushing the boundaries of thermal performance.
