Today, processors (CPUs) such as graphics processing units (GPUs) and RF amplifiers are developing enormous power densities. Heat generation increases with each new generation of hardware - at the same time, systems need to become more compact, more energy-efficient and more reliable. In many cases, air cooling can no longer reliably dissipate the required amount of heat: It reacts more slowly, requires more energy and needs larger heat sinks.

Liquid cooling for processors is therefore becoming the preferred technology for avoiding hotspots, keeping temperatures stable and reliably protecting sensitive electronics.

For this cooling to work, all components of the circuit - especially the connection technology - must be absolutely reliable. This is where the STAUFF QRC-FR series plug-in couplings come into play.

Liquid cooling has become a standard in IT, telecommunications and broadcasting systems. It enables:

• more efficient heat dissipation

• a lower energy requirement

• Compact designs for high-density systems

• Stable working temperatures

However, the media used there - usually water-glycol mixtures - place special demands on the material, seal and pressure resistance. This requires reliable connection components such as the QRC-FR series.

Particularly high requirements apply in cooling circuits for high-performance electronics:

• Leakage protection to protect sensitive electronics

• Chemical resistance to water-glycol mixtures

• Temperature and pressure resistance under dynamic loads

• Compact design for limited installation space

• Low-maintenance design to reduce downtime

This is particularly essential in data centres or media transmission systems - because any malfunction jeopardises uptime, safety and efficiency.

The QRC-FR series push-to-connect couplings are specially designed for the liquid cooling of high-performance electronic systems.

Technical features at a glance:

• Designed for water-glycol mixtures

• Stainless steel housing (1.4305, 1.4310)

• EPDM gaskets

• Nominal size DN 10 (3/8")

• Nominal flow rate: 10 l/min

• Maximum operating pressure: 3.5 bar - also uncoupled

• Temperature range: -30 °C to +100 °C

• High corrosion and chemical resistance

• Precision-manufactured seals for leak-free operation

• Compact, robust design

These properties make QRC-FR an ideal solution for highly sensitive cooling systems.

STAUFF QRC-FR couplings are used in high-performance broadcast transmission systems, among other applications.

These take on sustainable broadcasting tasks in today's networked world.

Other typical applications:

• Cooling distribution units (CDUs) for high-performance IT infrastructures

• Semiconductor and tube-based HF amplifiers

In all of these systems, the liquid cooling for processors must be absolutely stable. Kuggplen of the QRC-FR series ensure that connections remain securely and permanently sealed even under dynamic conditions.

Even though STAUFF has its roots in hydraulics, products such as couplings from the QRC-FR series show that our components are convincing far beyond this. This is particularly true in areas where:

• high reliability,

• precise manufacturing,

• robust materials and

• Absolute security

are required.

In addition to standard solutions, we also offer customised adaptations of the QRC-FR series:

• special materials

• Alternative seals

• Customised connection geometries

• Versions for special media or temperature ranges

Such customisations are often crucial, especially when it comes to liquid cooling for processors - because many cooling circuits are tailored precisely to the respective system.
