Heat Sink Performance Testing
... A wind tunnel and test fixture were designed to evaluate the heat sinks. In some testing apparatuses, some fluid bypasses over the top or around the sides of the heat sink. This problem is eliminated here by making the flow channel the same size as the heat sinks to be tested. A somewhat fuzzy photo ...
