COOLING
(Radiation and forced air)
At anode dissipations up to 250 W a low-velocity air flow directed on the anode seal and the
base generally will provide sufficient cooling. At higher dissipations the glass chimney should
be used for circulating forced air along the bulb. At 400 W anode dissipation at least 0.4 m
min. air should be passed through the chimney. For this purpose the static pressure below
the chassis should be min. 50 Pa if cooling as arranged in the recommended way.
