Cold Plates

Koolance manufactures a wide range of proprietary cold plates, from microfin designs for 10mm square thermal electric coolers to 1 meter-long ultraviolet LED arrays. Cold plates can be traditionally assembled with o-rings and screws, or brazed. Brazing is particularly beneficial for low-profile cold plates, but must be carefully performed to prevent distortion.

UV LED Cold Plate

Circular UV LED Array Cold Plate: This brazed copper model is just 10mm thick with barbs for 4mm ID tubing.

Specialized Semiconductor

Brazed Custom Cold Plate: For a proprietary semiconductor, Koolance constructed this nickel-plated copper cold plate. Custom stainless steel barbs were brazed to the water block during manufacturing, ensuring a leak-free design without any gaskets or assembly screws.

Mainboard Cold Plate

Mainboard Cold Plate: This specialized cold plate was developed for the ASUS P6T7 WS SuperComputer motherboard. It involves five separate cold plates connected with welded copper pipes.

Intel Xeon Phi Cold Plate

Intel Xeon Phi Coprocessor Cooling: Koolance designed this cold plate for a large university's super computing cluster. Construction is nickel-plated copper with a POM acetal top. Fittings are provided on the mounting bracket.

Electric Car Motor Controller

Electric Vehicle Motor Controller: This gold-plated copper and stainless steel brazed cold plate was designed for an electric car's motor controller.


Cooling systems can be supplied as drop-in assemblies, arriving pressure tested and filled with coolant. Below are examples of specialized components Koolance has made for a variety of industries.

Drop-In Unit

Multi-Directional Cooling System: For a special electronics cooling application, Koolance worked closely with a customer to design and manufactured this liquid cooling system.

Using a brazed aluminum heat exchanger and CNC machined reservoir and housing, it provides multi-directional operation by way of an automatic rotating inlet and priming pump.

Stainless Steel Manifold

Stainless Steel Manifold: This welded SUS manifold module was designed for a specialized datacenter server cabinet. Each inlet/outlet has an adjustable valve and LED display for balancing individual loop performance where pressure is not well regulated.

Components slide into the manifold using specialized Koolance blind-mating quick connect shutoff fittings.

Hot-Swap Pump Testing Rack

Hot-Swappable Pump Testing Rack: Koolance produced this stress test rack to validate flow rate performance of up to fifty PMP-400 pumps at a time. Pumps are hot-swappable with a convenient mechanical "pop-out" lever. Each pump's flow rate is displayed in front for verification.
