Connectors integrated into liquid cold plate
This customer was in need of an auto-coupling/blind-mate connector to replace an existing solution. The coupling is fitted at the rear of the transmitter power module’s cooling plate, with the other end connected to the power block. The operator then slides the power module into the power block where the electronics and couplings are to be connected for long periods. CEJN engineers took the Non-Drip series 577 and converted it into an auto-coupling. In order to avoid damage to sensitive electronics, spill-free disconnection was essential when the racks are removed for maintenance or replacement a couple of times a year.
Special aluminium parts
The power module’s cooling plate is made of aluminium, so to eliminate the possibility of creating corrosion caused by different material and to better fit the existing manifold design, the standard stainless steel coupling’s outer parts were replaced with aluminium. The inner parts, however, are still stainless steel to preserve the robust construction and to keep them compatible with cooling fluids, in this case water-glycol mixture.
The customer is very satisfied with the modified Non-Drip series 577 blind-mate connector. We were able to keep the coupling robust and cut costs by keeping the inner parts in stainless steel. To CEJN, every customer and application is unique. Reworking standard products is done frequently and our engineers thrive on coming up with alternative solutions.
