The high heat dissipation type dual panel display device according to claim 7, wherein the blowing member includes a lifting cylinder (21) disposed at a lower left side of the display housing (15), a driving shaft is coaxially disposed inside the lifting cylinder (21), a lifting blade (23) is disposed outside the driving shaft and engaged with an inner wall of the lifting cylinder (21) for pushing the air flow, a driving motor (24) is connected to a lower end of the driving shaft for driving the driving shaft to rotate, an air inlet port (22) for air inlet is disposed outside a lower end of the lifting cylinder (21), a speed reducer (20) is disposed at an upper end of the lifting cylinder (21), an input end of the speed reducer (20) is connected to the driving shaft, a transmission gear (19) is disposed at an output end of the speed reducer (20), a transmission gear ring is disposed outside the lower guide roller (18), the transmission gear ring is engaged with the transmission gear (19), the transmission gear (20) is engaged with the transmission gear ring for driving the transmission gear (19) to rotate the lower guide roller (18), the transmission gear (19) is engaged with the transmission gear ring for driving the lower guide roller (18) to rotate, a conical air duct (25) extending into a lower side of the display housing (11), and a plurality of the air outlet pipe (25) extending into the lower end of the display housing, reservoir (33) top at toper air duct (25) place is equipped with buffer memory gas cover (26), buffer memory gas cover (26) are passed to toper air duct (25) upper end, the buffer memory gas cover (26) outside is equipped with the air duct that is used for connecting buffer tank (14) air inlet.

9. The high heat dissipation type dual-screen display device according to claim 8, wherein a purification unit for purifying residual impurities inside the reservoir (33) is further disposed outside the reservoir, the purification unit comprises a filter box (32) for filtering the washing liquid, a filter screen is disposed inside the filter box (32), a water outlet end of the filter box (32) is communicated with the reservoir (33), and a water inlet end of the filter box (32) is provided with an extension pipe extending into the reservoir (33).

10. The method for using the high-heat-dissipation type dual-screen display device as claimed in claim 9, comprising the steps of:

the method comprises the following steps: the port of the display part (12) which is contacted with the outside is isolated through the transparent transmission belt (16), so that the external dust is prevented from being directly contacted with the surface of the display part (12), and a protection effect is achieved;

step two: gas is sent into a buffer box (14) through a blowing piece, the gas is sprayed to the back of a display part (12) along a gas spraying grid (13) so as to cool the display part (12), the gas is sprayed out from the side surface of a display gap (11) along gas spraying holes, a gas diaphragm is formed at the position of a transparent conveying belt (16), and therefore the probability that dust covers the transparent conveying belt (16) is reduced;

step three: the lower guide roller (18) drives the transparent transmission belt (16) to rotate in the display shell (15) in a circulating mode, and the dust removing component is matched to remove dust on two surfaces of the transparent transmission belt (16), so that the cleanness of the transparent transmission belt (16) is guaranteed.
