Thermal Thought Leadership with Celsia Heat Pipes

Our chosen business partner in the thermal management sector, Celsia Inc, is a renowned innovator in heat management technologies. When innovation is the destination, the journey is typically one of imagination and resourcefulness that can’t help but pick up a wealth of expertise on the way. And so it is with Celsia. Which is why I would like to share some of that expert wisdom.

For decades, heat pipes were the default two-phase device of choice for thermal engineers. Why? It was largely due to the cost advantages relative to more complex notion of vapour chambers. Heat pipes are used for heat transport, for which they still exhibit an advantage, and for heat spreading – typically using multiple pipes in close proximity.

They can be configured into an almost infinite array of shapes, moving heat from the evaporator to remote locations where it can be more easily cooled. For lower power applications, perhaps requiring only a single, small heat pipe, or those where heat must be effectively transported, heat pipes still dominate.

Celsia focuses its efforts on ‘difficult heatsink applications’, like those that require multiple heat pipes to transport heat over longer distances, or where a complex shape is required and two-piece vapour chambers are beyond the budget. As with all two-phase devices, thickness, wick porosity and type, and the quantity of working liquid are variables whose design can be adjusted and optimised to suit each application’s requirements.

In addition to creating specialty square heat pipes for improved thermal conductivity, Celsia is well versed in the design and manufacture of ‘thermo-syphons’ deployed where the condenser is especially far away from the evaporator. Celsia’s design engineers use sintered, mesh and grooved wicks in heat sink designs for a variety of industries. These advances have led to further innovations in Vapour Chamber design. And that’s something I will cover in detail in a future blog. In the meantime, watch this space, or call us if you’re too curious to wait!

What a way to start the New Year! Hot off the press is a significant announcement that we are delighted to be able to share. Thermal Issues Ltd has agreed an exclusive partnership programme with California-based Celsia Inc. – a world innovator in Heat Pipe and Vapour Chamber technology.

The agreement, which naturally we’ve been negotiating for quite some time, makes Thermal Issues the UK agent for the revolutionary Celsia range of application-specific thermal management products – comprising custom designs developed for challenging customer applications. So, as you can tell, a business model that already parallels our own beautifully.

Make no mistake, these inventive products are highly technical design solutions. Celsia specialises in custom heat sinks using two-phase devices. These are perfect for high heat flux applications, harsh or rugged environments, and where thermal management space is constrained. Through Thermal Issues Ltd, UK companies can now access thermal management expertise, as well as a product solution tailored to their exact needs.

How will it work? Pretty simple. Just contact us. We’ll get a handle on your thermal challenge – things like thermal requirements and space constraints – and run the calculations, backed up by our extensive knowledge of thermal management in general and heat pipe & vapour chamber technology in particular. Then we get back to you with detailed specifications ready for you to design in. And costs, of course.

This promises to be a very productive relationship for Thermal Issues Ltd and Celsia, and for UK manufacturers. It’s a new conduit for knowledge and products that solves age-old problems for designers.

Celsia is headquartered in Santa Clara, California, with production facilities in Taiwan.

Be sure to visit the Celsia website where you’ll find out that the company has shipped over two million solutions to global customers and holds more than 70 patents. In fact, Celsia was the pioneer of the ground-breaking one-piece vapour chamber design with heat sink integration a decade ago. Why is that ground-breaking? It delivers a cost-comparable alternative to heat pipes that is thermally superior and therefore hard to ignore.

Contact us any time to find out more. There’s a great deal to know.

Best regards and a Prosperous New Year - Neil
