CWT-PCB™

Open Loop Wind Tunnel

The CWT-PCB™ is a unique, fully controllable wind tunnel for thermal and air flow testing of multiple PCBs. The test chamber has a 2-D converging nozzle with a multi-point measurement area for sensor placement upstream of the test section. The test section is equipped with card guides to allow insertion of actual or simulated PCBs from the side panel.

The CWT-PCB™ wind tunnel is designed to test up to six PCBs side by side, as seen in an electronic cabinet. The wind tunnel can also be used for standard thermal characterization such as component, PCBs, cold plates, etc. The chamber can accommodate up to 6 PCBs with 13 mm (0.5") card-to-card spacing or 3 PCBs with 25 mm (1") card-to-card spacing.

The large test section is made of clear polycarbonate material to accommodate smoke flow visualization. The chamber has its own stand for placement of instruments. The wind tunnel is placed on castors for ease of transportation.

The CWT-PCB™ can be fitted with different fan trays to accommodate a broad air flow range. Individually controlled 24 volt-DC fans generate air flow and are fully compatible with the optional WTC-100 Wind Tunnel Controller for automated thermal characterization. Heating elements can also be added for elevated air temperature testing.
