VI. Description of the invention: [Technical Fields of the Invention] [0001] The present invention relates to a heat pipe and a heat dissipation module having the same. [Prior Art] [0002] A heat pipe is a heat transfer device that is filled with a proper amount of working fluid in a sealed, low-pressure, and thermally conductive metal casing, and is converted into a gas-liquid phase by using a working fluid in the casing. The principle of absorbing or releasing a large amount of heat works. The working fluid is usually selected from liquid materials with high vaporization heat, good fluidity, stable chemical properties, and low boiling point, such as water, ethanol, and acetone. The heat pipe has an evaporation end and a condensation end. When the evaporation end contacts the heat source to absorb heat, the working fluid therein is evaporated by heat and absorbs a large amount of vaporization heat, and the formed vapor body rapidly diffuses to the condensation end to cool and release heat, and then cools again. The liquid is formed and recirculated along the inner wall of the casing, so that the heat generated by the heat source can be transferred from the evaporation end of the heat pipe to the condensation end to be emitted. In order to accelerate the recirculation speed of the liquid after cooling, a capillary structure is usually disposed on the inner wall of the casing, and the burr structure is usually a small groove. The groove is greatly accelerated under the capillary adsorption force of the capillary structure. Liquid | body reflux rate. Since the working fluid in the heat pipe has a high circulation speed, the heat transfer efficiency is high, and the heat pipe is widely used in the field of heat dissipation. The first and second figures illustrate a conventional heat pipe 10 having a sealed metal housing 102 that is evacuated to a low pressure chamber and filled with a metered working fluid (not shown). A capillary structure 104 is attached to the inner wall of the housing 102, and the capillary structure 104 is a groove extending longitudinally along the inner wall of the housing 102. In use, the heat pipe 10 ends as an evaporation section 吸收 absorbs from the heat source 094133031 Form No. A0101 Page 4 / Total 21 Page 0993334021-0 1333050 On September 16, 2009, the heat of the replacement page was corrected, and the other end was used as a condensation section to release heat. The steam after the endurance vaporization of the working fluid is diffused from the evaporation section to the condensation section, and the cooled working fluid is recirculated along the capillary structure 104. [0004] Since the notebook computer is moving toward a light, thin, short, and small direction, when the heat pipe 10 is used for a notebook computer heat dissipation module, it is usually necessary to first press the heat pipe 10 into a flat shape to satisfy the inside of the notebook computer. Space restrictions. However, the heat pipe 10 has a small diameter, and when it is flattened, the distance between the casings 102 of the heat pipe 10 is reduced, and the droplets which are accumulated after the condensation of the steam in the condensation section B further reduce the distance between the casings 102, resulting in a decrease in the distance between the casings 102. The interface between the vapor diffusion and the liquid reflux creates an interactive shear force that prevents the liquid from flowing back to the evaporation section and, on the other hand, vaporizes toward the peak condensation stage. Due to the existence of the shearing force, the heat pipe i/o; the inner ^ 乍 乍 ^ is a large ring speed r island, 1 ν * \ greatly slows down, reduces the heat transfer performance of the heat pipe 10, the diameter of the casing 102 In the case of a small long heat pipe, even the condensed liquid cannot be smoothly returned to the evaporation section for heat dissipation. Factory - ΐ : , > .. . . . ^ S " ' , - [0005] In view of this, a steam that avoids diffusion to the condensation end and a condensed liquid that flows back to the evaporation end are provided. • A heat pipe with a fluid circulation rate is necessary. SUMMARY OF THE INVENTION [0006] Hereinafter, a heat pipe and a heat dissipation module will be described by way of embodiments. [0007] A heat pipe includes a cover body and a body. The body includes an evaporation chamber, a condensation chamber, an evaporation channel and a return flow. The condensation chamber is provided with a plurality of partitions, and at least one partition has a a cavity communicating with the outside, the evaporation chamber has a steam output side and a liquid input side, the condensation chamber has a steam input side and a liquid output side, the evaporation channel is set in the steam 094133031 Form No. A0101 Page 5 / Total 21 pages 099333402 Bu 0 1333050 On September 16, 099, the replacement side of the page is replaced with the steam input side and the evaporation chamber is connected to the condensation chamber, which is disposed between the liquid output side and the liquid input side and condenses. The chamber is in communication with the evaporation chamber, and a working fluid is filled in the passage formed by the evaporation chamber, the condensation chamber, the return passage, and the evaporation passage. [0008] A heat dissipation module includes: a heat pipe, a plurality of heat dissipation fins and a fan, the heat pipe includes a cover body and a body, the body includes an evaporation cavity, a condensation cavity, an evaporation channel and a return flow path The condensing chamber is provided with a plurality of partitions, at least one of the partitions has a cavity communicating with the outside, the evaporation chamber has a steam output side and a liquid input side, the condensing chamber has a φ a steam input side and a liquid On the output side, the evaporation channel is disposed between the steam output side and the steam input side, and communicates the burst chamber with the condensation chamber, the return channel is disposed between the liquid output side and the liquid input side, and connects the condensation chamber to the evaporation chamber. A working fluid is filled in the passage formed by the evaporation chamber, the condensation chamber, the return passage and the evaporation passage; the plurality of heat dissipation fins are disposed on one of the cover portions of the heat pipe and the condensation chamber. - v ' [0009] Compared with the prior art, the heat pipe has the following advantages: the steam and the condensate in the operation of the heat pipe flow in different passages, that is, the steam generated by the evaporation chamber is diffused by the evaporation passage To the condensation chamber, the condensate generated by the condensation chamber is returned to the evaporation chamber through the return passage, so that the steam generated by the evaporation chamber and the condensate generated by the condensation chamber flow in a passage in the heat pipe, thereby avoiding the interface between the steam and the condensate in the prior art. The shear force that produces the interaction affects the circulation of the working fluid, thereby increasing the heat transfer efficiency of the heat pipe. The heat dissipation module has the above heat pipe structure, and is used for heat transfer, and can combine the advantages of the heat pipe to better exert heat transfer.
