Description
Technical field
The utility model relates to a kind of pulsating heat pipe, relates in particular to a kind of concurrent flow pulsating heat pipe.
Background technology
Pulsating heat pipe is called oscillating heat pipe again, proposed by Japanese scholar H.Akachi the nineties in last century, the pulsating heat pipe of prior art is the simple but two phase flow heat transfer device of mechanism complexity of a kind of mechanism, it is that a long capillary is vacuumized, then capillary inside is charged into liquid, if capillary diameter is enough little, will form steam binding and liquid plug off and in the pipe, liquid carburation by evaporation when an end of pulsating heat pipe is heated, steam flow to the other end and emit heat and condense into liquid under small pressure reduction.Little caliber and the bending repeatedly of cold and hot end are two primary conditions that form pulsating heat pipe, pulse to transmit heat by phase transformation and vapour-liquid.Compare with general heat pipe, it is simple in structure, does not need the imbibition core, is not subjected to gravity effect, and caliber is little, and the heat pipe shape can be crooked arbitrarily, and adaptability is good, so manufacturing, operation and maintenance cost are low; Pulsating heat pipe is because its good performance is regarded as solving the heat transfer element that is hopeful most in the short space high heat-flux heat sink conception with future.
Though the pulsating heat pipe of prior art has above-mentioned all advantages, but the defective that exists is: because the caliber of traditional pulsating heat pipe is too little, its cold and hot end sealing difficulty is big, thus be difficult to seal by cast or welding procedure tight, thereby influenced heat exchange efficiency and realized commercial application.And requiring not blending of cold fluid and hot fluid in the heat exchanger mostly, this has just become to restrict the key factor that traditional pulsating heat pipe is used.Simultaneously, because the caliber of traditional pulsating heat pipe is little, be difficult for adding fin, heat exchange area is limited, has also influenced heat exchange efficiency.
Summary of the invention
The utility model provides a kind of concurrent flow pulsating heat pipe in order to solve the prior art above shortcomings; Sealing reliability height, the outer fin that easily adds of pipe can increase heat exchange area greatly, improve heat exchange efficiency, and easier realization industrialization is particularly useful in cooling electronic component and the tide of motorism system.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of concurrent flow pulsating heat pipe, comprise metallic plate, metallic plate is provided with the capillary conduit, separate by the capillary cell wall between the adjacent capillary conduit, described metallic plate bending, make the capillary conduit bend to snakelike pipeline, be provided with the working media that encapsulates under the vacuum in the capillary conduit, the working media in the capillary conduit forms steam binding, liquid plug in snakelike pipeline, and steam binding and liquid plug distribute alternately in the capillary conduit at random.
The capillary conduit is provided with a plurality of, and the capillary conduit becomes linear and is evenly distributed in the metallic plate.The cross sectional dimensions of concurrent flow pulsating heat pipe of the present utility model is much larger than conventional heat pipe.
The cross sectional shape of described capillary conduit is circle, rectangle, triangle, one or more the combination form in trapezoidal.
The equivalent diameter of described capillary conduit is between 0.5～3.5mm.
The working media of described capillary conduit is any among distilled water, methyl alcohol, absolute ethyl alcohol, acetone, R123, the R134a.
The liquid filled ratio of working media is 20%～70% in the described capillary conduit.
Described snakelike pipeline is open ended or closed circuit type.
Described metallic plate adopts high heat-conducting copper material or light high heat conducting aluminium to make.
The beneficial effects of the utility model:
(1) the utility model is owing to usedly make for the metallic plate of porous, profile is wanted prolate than conventional heat pipe, often require the not blending of cold and hot end fluid in the general heat exchanger, this just need add dividing plate and seal between cold and hot end, the tradition pulsating heat pipe is because caliber is little, big and the leakiness of sealing difficulty between pulsating heat pipe and dividing plate, the cross sectional dimensions of concurrent flow pulsating heat pipe of the present utility model is much larger than the cross sectional dimensions of conventional heat pipe, therefore cold and hot end sealing is more easily carried out, and a plurality of capillary conduits are arranged in the concurrent flow pulsating heat pipe, namely be equivalent to several traditional pulsating heat pipes, the sealing reliability height, and the seal operation amount also significantly reduces.
(2) the utility model since used be expanded metal, being easy to can increase heat exchange area, the raising heat exchange efficiency greatly at the outer interpolation of pipe fin.
(3) the utility model adopts porous flat pipe, and the product design that institute's processing and fabricating comes out is attractive in appearance, and more traditional pulsating heat pipe is easier to be applicable in cooling electronic component and the tide of motorism system easier realization industrialization.
