Description
Technical field:
The invention belongs to electronics cooling technology field, relate to the parts of being convenient to cool off semiconductor or other solid state devices.
Background technology:
Along with the continuous development of electronics packaging technology, the physical size of assembly is more and more little, and packaging density increases; The raising of chip performance, the also corresponding increase of its quantity of heat production causes the high heat density of electronic device to form.Therefore the effective heat dissipating method of seeking electronic device seems more and more important.
Conventional radiating mode mainly is to rely on the fin on the radiator to dispel the heat by heat conduction, and this mode can't satisfy the heat radiation requirement of high heat flux.
Shown in Figure 4: the circular form heat pipe is a coiled pipe, and it sealed at both ends is connected to form a loop.In the pipeline that this heat pipe flows, at least need a float-type unidirectional valve 19 to limit the one-way flow of steam and liquid, evaporate in bringing-up section, condense at cooling section, under the big or unsettled situation of heat output, the motion of float-controlled valve 19 is restricted, and can produce pulsation at heat output, not only influence the reliability of heat pipe, also be difficult to realize the heat pipe microminiaturization.
As shown in Figure 5: loop type heat pipe is that the passage of the passage of liquid and gas is separately formed circulation circuit.Returning of fluid makes pipeline interior formation flow resistance and guides the capillary structure that condensed fluid returns the evaporation part.When causing caloric receptivity when endotherm section very big, be subjected to the restriction of the capillary force limit, bringing-up section can not get sufficient feed flow.
Summary of the invention:
The object of the present invention is to provide a kind of pulsating heat pipe that is suitable for the cooling of modern high energy consumption electronic equipment, its volume is little, in light weight, cost is low, easy to process, heat-transfer capability is strong, stable and reliable operation and noiseless.
Technical scheme of the present invention is:
I. pulsating heat pipe is made of aluminium cell board 1 and dull and stereotyped 2; Have in a side milling of aluminium cell board 1 to comprise that 3, the one groups thin straight tubes 4 of one group of thick straight tube that are arranged parallel to each other are connected curved passage 5 with one group, thereby constitute capillary slot; Dull and stereotyped 2 are covered with cell board 1, and capillary slot has become an enclosed cavity thus; The working fluid of filling 30%～70% in the enclosed cavity; The curved passage 5 of one end is as the bringing-up section 6 of heat pipe, and the curved passage 5 of the other end is as the radiating segment 7 of heat pipe; Passage between bringing-up section 6 and the radiating segment 7 is as the adiabatic section of heat pipe.
II. pulsating heat pipe is connected to form by one group that is arranged parallel to each other thick straight pipeline 14 and thin straight pipeline 15, and every two adjacent pipelines couple together with bend pipe 16; Heat conduction working solution forms the one-way plug one shape and flows in pipeline under the pressure that heat effect produces, in bringing-up section 17 heat absorption evaporations, in radiating segment 18 heat release condensations.
Advantage of the present invention is: pulsating heat pipe has high heat transport limitation and low thermal resistance, and has in light weight, advantage such as cost is low, easy to process, reliable and noiseless, is suitable for the cooling of modern high energy consumption electronic equipment.

Embodiment:
Fig. 1, Fig. 2 have described the structure of pulsating heat pipe of the present invention.Pulsating heat pipe is made of aluminium cell board 1 and dull and stereotyped 2; Have in a side milling of aluminium cell board 1 and to comprise that 3, the one groups thin straight tubes 4 of one group of thick straight tube that are arranged parallel to each other are connected curved passage 5 with one group and the capillary slot that constitutes; Dull and stereotyped 2 are covered with cell board 1, and capillary slot has constituted an enclosed cavity thus; The working fluid of filling 30%～70% in the enclosed cavity; The curved passage 5 of one end is as the bringing-up section 6 of heat pipe, and the curved passage 5 of the other end is as the radiating segment 7 of heat pipe; Passage between bringing-up section 6 and the radiating segment 6 is as the adiabatic section of heat pipe.
When pulsating heat pipe of the present invention moves, the fire end of pulsating heat pipe is heated, radiating end is cooled, because pipeline has the branch of thickness, and form different flow resistances, the gas-liquid mixture (gas is main) that working solution forms in evaporation ends gasification selects to know a little about that upwards to be slug flow moving, and it is moving to select thin passage to be slug flow downwards through the mixture (liquid is main) after the condensation segment partial condensation, forms continuous circulating; The evaporation and the condensation of pulsating heat pipe amount working solution are delivered to colling end with heat from fire end; Working solution in the whole enclosed cavity forms liquid plug and vent plug under capillary effect, in bringing-up section 6 heat absorption evaporations, grow up to air pocket 8, and liquid plug 9 shortens gradually; Under the differential pressure action of bringing-up section 6 and radiating segment 8, air pocket 8 is being carried secretly and is being lacked liquid plug 9 and flow to radiating segment 7 along knowing a little about 3: when their arrive radiating segment 7, and steam heat release condensation, bubble 8 diminishes, and liquid plug 9 is elongated.Under the effect of inertia force and gravity, elongated liquid plug 12 and the bubble 11 that diminishes flow to bringing-up section 6 along thin passage 4; When bubble 8 and liquid plug 9 arrival bringing-up sections 6, just finished a circulation.In circulation, all bubbles 8 and liquid plug 9 all are to flow along a direction.Hydraulic fluid continues to be subjected to thermal evaporation to begin next circulation in bringing-up section.In the circulation of working solution, finish the transmission of heat.
Fig. 3 has showed pulsating heat pipe frame mode of the present invention.Pulsating heat pipe is connected to form by one group that is arranged parallel to each other thick straight pipeline 14 and thin straight pipeline 15, and every two adjacent pipelines couple together with bend pipe 16; Heat conduction working solution forms the one-way plug one shape and flows in pipeline under the pressure that heat effect produces, in bringing-up section 17 heat absorption evaporations, in radiating segment 18 heat release condensations.
Pulsating heat pipe of the present invention, the flow direction that working solution limits by mutual arrangement extra heavy pipe road and tubule road is done continuous unidirectional circulating by the pressure reduction under the heat effect in pipeline, and the flow direction of its vent plug 8 and liquid plug 9 is all identical, and flow resistance is very little.Therefore, heat output is very high, and heat pipe can be realized remotely transferring.
In service at heat pipe does not have the moving component of check-valves and so on, has only stable unidirectional the circulating of working solution, has guaranteed its performance reliably and with long-term.
It is easy to realize miniaturization, is easy to production and processing, only needs to form on one flat plate a capillary slot, and perhaps linking together that one group of extra heavy pipe road and tubule road replace, heat pipe just has been shaped.
