The utility model discloses a CRT (
Cathode Ray Tube) graphic
display device, which relates to the field of
electronic equipment and comprises a device shell, a CRT imaging device is arranged in the device shell, a cooling device is arranged around the CRT imaging device, the imaging device comprises a
kinescope, one end of the
kinescope is provided with a display surface, and one end of the
kinescope far away from the display surface is provided with a
data connection port. And the
data connection port extends out of the device shell. The efficient cooling device is integrated in the device shell, the device not only comprises the fixing plate attached to the outer surface of the kinescope and the heat dissipation outer ring surrounding the
data connection port, but also realizes liquid cooling circulation through the infusion tube and the through groove, so that the temperature around the kinescope and the data connection port is effectively reduced, and meanwhile, the heat dissipation effect of the kinescope and the data connection port is improved. And through the design of mechanical structures such as the sliding blocks and the connecting rods, flexible adjustment and stable supporting of the heat dissipation outer ring are achieved, the heat dissipation efficiency is improved, and the stability of the structure is enhanced.
