Problems solved by technology

When the toothed wind wheel 3 is started, the hot air on the surface of the radiator 1 is drawn through the end of the toothed wind wheel 3, but, because the linear velocity from the center of the toothed wind wheel 3 to the outer circumference is different (the closer the The lower the linear velocity at the center, see Figure 8 As shown in , the linear velocity at point O is zero, and the linear velocity at point P is smaller than the linear velocity at point Q), therefore, the heat dissipation on the surface of the radiator 1 is uneven, and the temperature rise is the most serious at the position near the center of the tooth blade wind wheel 3 At the same time, since the heating element 4 is generally installed in the center of the bottom of the radiator 1, from this point of view, the air-cooled radiator 1 with this structure is easy to cause the heating element 4 to burn out

Abstract

The invention relates to a heat dissipation technology extracting hot air at a high speed through tooth blades. The heat dissipation technology comprises a heat dissipater and a tooth blade wind wheel doing rotational motion, wherein the rotational peripheral surface of the tooth blade wind wheel is close to or makes contact with the surface of the heat dissipater, and the tooth blade wind wheel is formed by distributing a plurality of tooth blades in an annular mode. According to the heat dissipation technology extracting the hot air at a high speed through the tooth blades, the tooth blades walk on the surface of the heat dissipater for extracting the heat released by the surface of the heat dissipater, external cold air can be brought to the surface of the heat dissipater for heat exchange, and therefore efficient heat dissipation is realized through repeated recycling; the heat dissipation density is greater than or equal to 10 watts per square centimeter, the speed of extracting the air on the surface of the heat dissipater by the tooth blades is even close to the sound speed, and the ultra-efficient heat dissipation effect is realized and is improved by dozens of times compared with the heat dissipation effect of traditional heat dissipation modes.
