Aluminum nitride ceramics are electrically insulating and have excellent thermal conductivity, making them ideal for applications that require heat dissipation. We offer custom aluminum nitride parts such as Large-Area Liquid Cooler.

The monolithic structure made of Aluminum Nitride (AlN) is airtight after firing, making it perfect for high external pressure applications. The advantages of AlN Ceramic for large-area liquid coolers are that the design of the monolithic heat sink provides excellent heat transfer from the ceramic to the cooling water and both cooling connections are on the same side which are inserted with two seal rings. It’s suitable to be used in semiconductor elements.
