HYDAC has on offer cold plate technology that can be used to ensure a constant and cool temperature in electronic components. The importance of this cannot be underestimated taking into account that most electronic equipment failures are heat-related.
HYDAC Managing Director Mark Keen emphasises that heat-related electronic equipment breakdowns are a “notorious” problem in the industry.
“The more electronics you put into the panel, the hotter it gets. So to compensate for the heat we normally put in a vent and a fan and that lets the air circulate into the control cabinet and cool down the panel. But that’s a problem in very dirty or wet environments because it potentially lets moisture and/or dust in, and the electronics are very sensitive to moisture contamination,” Mr Keen says.
In light of this HYDAC developed a cold plate system by inserting an aluminium plate replacing the backing plate of the panel which can directly act as a heat sink for the electronics. This means that all the heat generated inside the box can be transferred to the cold plate panel and then removed via a cooled fluid circulated inside of the heat sink and completely separate to the electronics within.
Mr Keen explains that there’s never any possibility of the cooling fluid touching the electronics as they are “totally” separated, making it a “very safe” system.
“And what we can also do is seal the cabinet >IP68 and we can purge the cabinet with nitrogen. It means that we can seal the electrical cabinet completely. We can fill it with nitrogen – which is totally dry – and all heat management can take place without any possibility of dust or moisture ever reaching the electronics. So that's a really unique solution. And it's a solution which is absolutely perfect for the Australian mining and heavy industry environments where you have a lot of risk of contamination and electronic management is a constant problem.”
HYDAC’s cooling systems department forced the electronics on an electrical panel to get hot by heating the back plate to demonstrate the application of cold plate technology for electrical cabinet cooling by temperature.
With an ambient temperature of 40 to 50°C the electronics becomes overheated very quickly, but with the application of the cold plate technology an internal cabinet temperature of around 30°C was maintained, which is ideal for the efficiency of the electronics.
"This is revolutionary technology,” Mr Keen underscores.
HYDAC National Development Manager for Cooling Systems Andrea Cimadoro agrees with Mr Keen, adding that this type of technology is ever more welcome as the cooling of electronic components, systems or apparatus increasingly becomes an everyday challenge for HYDAC, stakeholders and technicians in the field.
HYDAC, Mr Cimadoro says, has achieved much success in this sector mainly through the use of air-to-fluid type systems.
“We have already efficiently cooled lithium-battery storage, static synchronous compensator (STATCOM) and electrical racks or data centres, especially Bitcoin data centres. We have successfully cooled numerous data centres or databases using submergible cooling,” he says.
“We have many references that stand testament to this work, which is a big, important and ever growing part of our business, especially in the last five years.”
Mr Cimadoro concludes by highlighting that HYDAC has the cooling know-how for any type of cooling “challenge”.
“Our engineering team is capable of providing a customer with the right solution for the cooling of any electronic apparatus from air-to-fluid, fluid-to fluid, cold plate to fluid (chiller) or cold plate to fluid with and air-to-fluid main ring system.
“So horses for courses and application to application: within the cooling group we can say with assurance that HYDAC has all the technology and all the components and subcomponents to create a bespoke solution for any customer in need of cooling electronic devices.”
