Direct To Chip Cooling Coolant PFPE JHT Series

Direct-to-chip (DTC)-also known as cold plate cooling or direct liquid cooling (DLC)-is a server cooling method that involves circulating liquid directly over components to dissipate heat. A flat, rectangular component with a chamber-like structure-made of a highly conductive material such as copper and known as a cold plate-is attached to the server's heat-generating components.

 

The cold plate contains channels or tubes through which the coolant flows. As the coolant passes through the chamber, it absorbs heat from the components and cools them. The heated coolant then exits the chamber and is cooled in an external heat exchanger or expelled from the system. This direct contact between the liquid coolant and the server components enables efficient heat transfer, ensuring effective server cooling.

Our JHT series direct-to-chip cooling fluid is a PFPE fluid. It is a dielectric fluid meticulously formulated and designed to meet the extreme demands of direct-to-chip applications.

Superior dielectric strength:A key requirement for direct-to-chip cooling is that the coolant must be electrically insulating. JX fluid possesses an exceptionally high dielectric constant, ensuring that any accidental leakage from the cold-plate circuit onto active components does not cause a short circuit, thereby protecting millions of dollars in IT infrastructure.

Exceptional thermal properties:The fundamental function of the coolant is to absorb and transport heat. The JHT series formulation features an optimal balance of thermal conductivity and specific heat capacity, enabling it to efficiently capture heat from the chip and transport it to the heat exchanger, thereby maintaining lower junction temperatures and preventing performance throttling.

Material compatibility and corrosion inhibition:The internal environment of a cooling circuit involves a variety of metals (copper, aluminum, nickel) and polymers. The JHT series coolant is chemically inert and incorporates advanced inhibitor packages that prevent the corrosion and degradation of all wetted materials over extended periods. This ensures system longevity and prevents clogging caused by corrosion by-products, which can destroy micro-channel cold plates.

Low viscosity and pumping efficiency:The viscosity of the JHT series fluid is optimized for low flow resistance. This reduces the energy required by pumps to circulate the coolant through the intricate micro-channels of the cold plates, contributing to a lower overall Power Usage Effectiveness (PUE) for the entire direct liquid cooling data center facility.

Long-term stability and low maintenance:Designed for a long service life, the JHT series coolant remains stable across a wide temperature range, resisting thermal degradation and oxidation. This reduces maintenance frequency and the total cost of ownership (TCO) of the cooling system.
