Internal tooth rib on level-one heat-dissipating pipe can cause the disturbance of heat exchange air-flow, and the gas in heat exchange air-flow edge will be moved to
The centre of heat exchange air-flow, the gas among heat exchange air-flow will be moved to the edge of heat exchange air-flow, hand in heat
Gas among scavenging flow will repeatedly be contacted with the inner tubal wall of level-one heat-dissipating pipe during heat exchange air-flow advances, and heat is handed over
Change that frequency is big, can adequately be in level-one heat-dissipating pipe heat exchange air-flow edge gas it is multiple be moved to heat exchange air-flow
Centre, the gas among the heat exchange air-flow it is multiple be moved to the edge of heat exchange air-flow, and then allow and handed in heat
The multiple inner tubal wall with level-one heat-dissipating pipe contacts gas among scavenging flow in advancement, and then quickly level-one
Heat heat exchange on heat-dissipating pipe is gone out, and heat exchange effect is more preferably.
Embodiments of the present invention are described above in conjunction with attached drawing, however, the implementation is not limited to the above embodiments, this field
Those of ordinary skill can be with various changes and modifications may be made within the scope of the appended claims.
