Heatpipe heatsinks for powerful heat removal
Efficient heat transfer from the source to the cooler
A key feature of heatpipe heat sinks is the utilisation of the phase transition of a liquid within small, highly thermally conductive copper tubes (heat pipes): When heated at the heat source, the water in the heat sink pipe evaporates and condenses again at colder points. This enables heat to be transferred quickly and efficiently to another location. Heat pipe cooling (heat pipe sink) combines the advantages of heat pipes with those of traditional and cost-effective heat sinks, such as extruded aluminium heat sinks. This results in a compact design and makes heat pipes ideal for applications where space is limited. In addition, heatpipe heat sinks operate passively: they require no external power source and contain no moving parts, which makes them particularly reliable.
Advantages of heatpipe cooling solutions
- Very good heat conduction
- Even temperature distribution
- Ideal for heat dissipation in confined installation situations
- Can be combined with various production technologies
- Heat dissipation over long distances possible
- Design freedom by increasing the number of heat pipes
- Can be installed largely independent of position
- Robust and low-maintenance design
The perfect team for CPU coolers: heatpipe + heat sink + fan
To increase performance, heatpipe coolers are combined with active fans, particularly in PCs, to dissipate the high power loss of microprocessors more quickly. Their ability to dissipate heat over greater distances also offers design freedom. This makes them the preferred choice for high-performance components in desktop computers, notebooks and compact electronics in a wide range of applications.

Heatpipe cooling solutions in use
Applications for this innovative technology can be found in particular in electronic systems that require efficient dissipation of power loss due to their cramped design or very high heat generation.
In IT server and computer technology,CPU coolers heat pipes are often used to cool processors and graphics cards in workstations and PCs, as PC heat pipes enable rapid heat transfer.
In notebooks and laptops, heatpipe CPU coolers are ideal for use in portable devices due to their compact design, where space and weight are decisive factors. This is why they are sometimes referred to as notebook heat pipes.
In electromobility , heatpipe heat sinks are used in the charging technology of charging stations, but also in stationary battery storage systems to cool their control units, voltage converters and rectifiers.
In lighting technology, modern LED lighting generatesconsiderably less heat than classic halogen lighting, but LED technology is also more heat-sensitive - especially with high-performance LED lamps, the high heat development must be dissipated quickly using heat pipe LED cooling.
In the telecommunications industry,heat pipe sink heat sinks are used to cool high-performance transmission systems.

EKL manufacturing processes for heat pipe cooling solutions
Ingenious physics: how heat transport works in a heat pipe
A heat pipe is an efficient heat transfer mechanism based on a two-phase heat transfer principle. It is a metallic, tubular body that is hermetically sealed and can transfer heat over long distances with minimal losses. These components are particularly common in the computer industry, where they are used in CPU coolers to transfer heat from the contact surface to the cooling fins. The heat is absorbed at the evaporation end of the heat pipe and released into the ambient air at the condensation end. The transport process utilises the latent heat of evaporation and condensation in the adiabatic section of the heat pipe. An internal vacuum lowers the boiling point and thus enables heat transfer at lower temperatures.
