Description
Technical field
The present invention relates to technical field of heat dissipation, more particularly to a kind of high efficiency and heat radiation pipe.
Background technology
Heat conducting pipe has been widely used in the electronic building brick for having larger caloric value because it has the advantages of compared with high heat transfer amount
In.When heat conducting pipe works, using under tubular body near vacuum state, the relatively low characteristic of hydrodynamic boiling point is made in filling, makes its work
Make liquid and carburation by evaporation after heat caused by heating electronic package is absorbed in its evaporation part, condensation part is moved to heat, and
In condensation part, liquefaction, which condenses, discharges heat, and electronic building brick is radiated so as to realize.Working media after the vaporization
Evaporation part is back in the presence of heat conducting pipe capillary structure, continues to be condensed by carburation by evaporation and liquefaction, is leading working media
Inside heat pipe shuttling movement, heat caused by electronic building brick is endlessly conducted.Under prior art, due to evaporator section
Interior wall construction it is more single, disengagement area is smaller, the factors such as gas-liquid conversion efficiency is low influence so that the heat-conducting effect of heat conducting pipe
It is poor.

Brief description of the drawings
Fig. 1 is a kind of structural representation of high efficiency and heat radiation pipe of the present invention.
Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
As shown in figure 1, a kind of high efficiency and heat radiation pipe in the present embodiment, including body 1, the cavity length side along the body 1
To evaporator section, adiabatic section and the condensation segment set gradually (there is disclosure the part in the prior art, will not be described here)；
Return pipe 21 is provided through in the middle part of the cavity of the evaporator section, the periphery of the return pipe 21 is circumferential to be evenly equipped with 3 liquid works
Matter absorbing unit 22, the peripheral of the liquid working substance absorbing unit 22 burn between the inwall of body 1 filled with metallic particles
Statement of account member 23；The liquid working substance absorbing unit 22 includes absorption main body 221, and extension extension in the absorption main body 221
Multiple absorption tributaries 222 of both sides, the absorption tributary 222 are set with absorption main body 221 insertion, the adjacent liquid work
One end of the absorption main body 221 of matter absorbing unit 22 is extended in the cavity of the return pipe 21.
Specifically, absorption main body 221 described in the present embodiment and the absorption tributary 222 are disposed as running through the evaporation
