Claim of US Patent No. 9,907,204

1. A heat dissipation device, applied to a display device, comprising a temperature monitoring unit, a control unit, a movement
unit, and a plurality of heat dissipation fans, wherein:
the temperature monitoring unit monitors an environment temperature of each predetermined region of the display device;
the control unit is connected to the temperature monitoring unit, and determines to-be-cooled regions according to a monitoring
result of the temperature monitoring unit and then send a control instruction to the movement unit, wherein the control unit
determines the to-be-cooled regions by:

comparing the environment temperatures of the predetermined regions detected by the temperature monitoring unit with a predetermined
threshold value, and determine the predetermined regions of which the environment temperatures are higher than the predetermined
threshold value as high-temperature regions;

determining all the high-temperature regions as the to-be-cooled regions when an amount of the high-temperature regions is
not larger than an amount M of the plurality of heat dissipation fans; and

ranking priorities of all the high-temperature regions according to the environment temperatures of the high-temperature regions
and/or importance thereof and determine M high-temperature regions with highest priority as the to-be-cooled regions when
the amount of the high-temperature regions is larger than the amount M of the plurality of heat dissipation fans;

the movement unit is connected to the control unit, and moves the plurality of heat dissipation fans to the to-be-cooled regions
to be cooled in response to the control instruction; and

the plurality of heat dissipation fans are connected to the movement unit.
