This is a liquid cooled heat-sink for a diesel engine computer. It uses the diesel fuel from the engine as the cooling source while it flows through the plate. The original design from the customer was a three piece stamping that was silver soldered together and then pressure tested for leaks. This design was difficult to manufacture. The stamped parts were not flat enough and the silver soldering and the three piece design provided many places for leaks and ultimately needed to be re-designed. High-Star proposed a two piece design that had the path for the fuel machined into a solid steel plate. Next, copper wire is placed in the path and the steel plate is spot welded on top to trap the copper inside. Afterward, the complete plate is sent through the braze furnace. The end result is a part that is durable, sealed and eliminates leaks at a reduced cost to the customer.
