Abstract
The utility model discloses a column heat pipe, comprising a hollow pipe body. Operating fluid is in the pipe body. The inner wall surface is surrounded by continuous grooves. A plurality of upright ribbed columns are arranged on the inner wall surface of the pipe body and extend to the center of the hollow pipe by the powder sintered method. Porous capillary organizations are formed on the surfaces of the ribbed columns. Thereby, ribs can be firmly sintered more in the pipe body by the installation of the grooves. Meanwhile, the area and effect of a condensing end surface in the pipe body is increased. Hot gas which is generated by heat exchange of heat quantity can be rapidly cooled into liquid, and the cooled liquid can be moved to the porous ribbed columns by the capillary method, and then can be conducted to the bottom of the pipe body. The variation of the vapor phase of the heat pipe is enlarged, and the heat radiation efficiency of the whole heat pipe is enhanced.
Description
Technical field
The utility model relates to a kind of Column shaped heat pipe, relates in particular to the heat exchange of a kind of electronic building brick (as CPU) that be used to generate heat, and the vapour phase variable quantity of heat pipe is strengthened, and speeds up, and improves the Column shaped heat pipe of the radiating efficiency of whole heat pipe.
Background technology
Along with science and technology develops fast, the speed of computer on computing is carried out is more and more faster, and when especially the arithmetic speed of central processing unit was fast more, the heat that is produced during operation was also more and more higher.For intensive heat can effectively be loose outside main frame, keep central processing unit and under permissive temperature, operate, can on central processing unit, be provided with heat abstractor usually, be used for assisting the central processing unit heat radiation, increase heat-sinking capability.But along with the arithmetic speed of central processing unit is fast more, under the more and more higher situation of the heat of generation, if general heat abstractor still is made of aluminium extruded type radiator and radiator fan, the heat radiation of the central processing unit of then can at all can't loading.
Therefore, as shown in Figure 1, a kind of heat pipe is disclosed.This heat pipe 10a comprises a hollow tube 1a, is provided with working fluid in body 1a, is covered with capillary structure 2a on the internal face of body 1a.In use, heat pipe 10a and radiator are combined, again heat pipe 10a is placed on the central processing unit, the heat that central processing unit operation back is produced can be absorbed by the working fluid in the body 1a and carry out heat exchange, and the heat that is produced after the heat exchange can upwards distribute, because body 1a top is away from heating place, temperature is lower, so can make hot gas be cooled to liquid on body 1a top, liquid is directed to body 1a bottom by capillary structure 2a again, thereby carries out heat exchange constantly.
Above-mentioned known heat pipe has following defective:
(a) the capillary structure 2a in the heat pipe 10a only pastes on body 1a internal face, do not combine with body 1a is complete, if there is the space to exist between body 1a and the capillary structure 2a, then can reduce speed and the time of capillary structure 2a guiding liquid to body 1a bottom, radiating efficiency can't be improved.
(b) only have end face to can be used as condensation end owing in the body 1a, so the area of condensation end is big inadequately, makes the variable quantity of vapour phase and speed fast inadequately, and radiating efficiency can't be improved.
(c) known heat pipe 10 since only within it wall be provided with capillary structure 2a, the formed liquid in cooling back can't very promptly be absorbed by capillary structure 2a, thereby has reduced the heat exchanger effectiveness of working fluid.
In view of the defective that exists in the above-mentioned prior art, the utility model designer is by means of being engaged in the sector experience for many years, and in line with excelsior spirit, the active research improvement has the generation of the utility model " Column shaped heat pipe " then.
The utility model content
A purpose of the present utility model is to provide a kind of Column shaped heat pipe, makes being combined on the internal face that capillary structure in this heat pipe can be more firm, improves the absorption guiding speed and the time of capillary structure.
Another purpose of the present utility model is to provide a kind of Column shaped heat pipe, makes the area and the effect that can increase condensation end in this heat pipe, and the hot gas that heat is produced after heat exchange can be cooled to liquid apace.
Another purpose of the present utility model is to provide a kind of Column shaped heat pipe, is uniformly distributed with capillary structure in this heat pipe, and the vapour phase variable quantity of heat pipe is strengthened, and speeds up, thereby has improved the radiating efficiency of whole heat pipe.
Of the present utility model one is characterised in that this heat pipe includes a hollow tube, is provided with working fluid in this hollow tube, is surrounded with continuous channel at the internal face of this hollow tube.Center along the internal face of this hollow tube towards this body is extended and is provided with the rib post of a plurality of settings in powder sintered mode, forms the capillary structure of porous matter on the surface of this rib post.Thus, utilize the setting of this groove to make sintering that rib can be more firm in body and increased the area and the cooling effect of condensation end in this body, the hot gas that heat is produced after heat exchange can be cooled to liquid fast, and cooled liquid more can be moved on the rib post of porous matter rapidly in the capillary mode, conduct to the body bottom surface again, can carry out heat exchange constantly.
Another feature of the present utility model is that this groove is arranged on the internal face place of body in mode radially, and a plurality of rib posts with capillary structure then are erected in the body with axial manner.This radial groove can make cooling liquid be directed to rapidly on the rib post, and the hot gas after the heat exchange can upwards distribute fast from the runner of each rib intercolumniation.
Column shaped heat pipe of the present utility model can make sintering that rib can be more firm in body, increases the area and the effect of condensation end face in the body simultaneously, and the hot gas that heat is produced after heat exchange can be cooled to liquid fast, improves the radiating efficiency of whole heat pipe.
