Profile heat sinks from CTX

The CTX standard profile heat sinks come in widths of 12,4 to 750 mm, weighing between 130 g and 75.1 kg. Their thermal resistance Rth ranges from 81,6°C/W to 0.04°C/W.

CTX assists customers in selecting the best profile heat sink for their application by calculating the necessary capacity based on customer specifications. Should it be necessary to produce application-specific profiles that require special tools, we would be delighted to provide you with a competitive offer.

The better the contact between the electronic component and the heat sink, the lower the thermal resistance. As dimensional deviations are unavoidable with continuous casting, there is sometimes an air cushion between the component and the heat sink. In order to eliminate the resulting poor thermal conductivity which in turn leads to higher temperatures in the component, reduced performance, etc., CTX offers its customers CNC-machined profile heat sinks. To find out more, simply give us a call!

CTX profile heat sinks are made from a specially developed continuous cast aluminium alloy that offers excellent thermal conductivity properties of 180 W/mK. On request, we equip our heat sinks with a special surface finish to optimise the heat dissipation. Our finishing methods include

• Anodising
• Chromating
• Powder coating
• Wet painting
