Kenwood TS-590S manual Structural Features, Cooling

7 STRUCTURAL FEATURES

7.1 Cooling

We have designed the chassis of the TS-590S to endure heavy-duty operation.

The PCBs are placed as follows: FINAL UNIT on the upper side of the chassis, TX-RX UNIT and LO UNIT on the lower side, CONTROL UNIT beneath the LO UNIT, NB UNIT and DISPLAY UNIT in front.

We have placed two cooling fans in the front of the chassis.

The cooling fans have two operation modes: LO and HI. By rotating two fan motors at a lower revolution speed, we aimed to reduce the operating noise.

We have optimized the chassis structure using computer-aided thermal analysis to improve the heat dissipation performance. We have designed the chassis to facilitate smooth air flow.
