3.CONSTRUCTION OF NB59S
The drawing below shows an example method for transistor heat dissipation. The attached aluminum cooling fins should fixed using silicon rubber to a metallic water tank, etc. with sufficient head dis- sipation capacity.
(It is recommended to use a plastic water tank. However, if a metallic water tank is absolutely must be used, be sure to insulate it from the power supply line.)
