Fig. 3, be A portion partial enlarged drawing among Fig. 2.
Fig. 4, for structural representation side view cutaway drawing of the present invention.
Below in conjunction with accompanying drawing the present invention is further elaborated.
As Fig. 2, Fig. 3, shown in Figure 4, the evaporation part 21, steam channel 22, condensation part 23, fluid Return Channel 24, the heat that the present invention includes loop 2, are series on the loop 2 in regular turn pass piece 3 and contiguous block 4.
Be filled with an amount of liquid in the loop 2, liquid-filled amount means by filling up capillary structure to the volume that fills up loop 90%.
Fluid Return Channel 24 and steam channel 22 are the pipeline of not sharing mutually, and promptly steam channel 22 and fluid Return Channel 24 are pipeline independently separately.
The flow resistance of fluid in fluid Return Channel 24 is greater than the flow resistance of fluid in steam channel 22, cause the imbalance of hot-fluid in the loop 2, to form the dissymmetrical structure that flows in the loop, so can produce the pressure differential phenomenon, the steam that evaporation part 21 is formed be easy to and natural stability ground folk prescription to 23 mobile towards the condensation part, and in the condensation part 23 condensations form condensate liquid stream, make the liquid stream of condensation, not concretive gas is together with uncooled steam flow, under loop pressure reduction and guiding structural effect, simultaneously towards fluid Return Channel 24 stably folk prescription and be back to evaporation part 21 to flowing through fluid Return Channel 24.
Condensation part 23 of the present invention is the pipeline of the heat radiation position in loop 2, this part is main heat dissipation region, certainly the pipeline in loop 2 itself also is good radiator structure, condensation part 23 is provided with contiguous block 4, in contiguous block 4, be provided with connecting channel 41, connect steam channel 22 and fluid Return Channel 24 with connecting channel 41; Also can make the pipeline of condensation part 23 or through contiguous block 4 to join with integrated radiator or groups of fins 25, be preferably groups of fins 25, so contiguous block 4 is to represent with the pipeline pattern, but be provided with the connector of corner formula.Just condensation part 23 joins with heat-exchange device as heat radiation, and heat-exchange device is the evaporation part in radiating fin group, radiator, cooling tower or another group loop.
As shown in Figure 2, steam channel 22 is a pair of pipeline, that is to say to be provided with that single pipeline or two pipelines are above to form steam channel 22 in parallel, and the flow resistance summation that makes each steam channel 22 is less than fluid Return Channel 24.That is fluid Return Channel 24 sectional areas less than or length greater than steam channel 22 sectional areas or length; Also can be fluid Return Channel 24 sectional areas less than reaching length greater than steam channel 22 sectional areas and length.Form the state that flow resistance is little, flow velocity is big in the steam channel 22, and form the state that flow resistance is big, flow velocity is little in the fluid Return Channel 24, asymmetric to produce the hot-fluid that painstakingly forms in the loop 2, impel to form the flow direction of determining.Fluid Return Channel 24 is in the drawings for only establishing single pipeline, it also can be established two and go up to form fluid Return Channel 24 in parallel, as long as meet aforesaid condition with flow resistance greater than steam channel 22 flow resistances, and make condensed fluid return evaporating area 21 through fluid Return Channel 24, naturally produce the pilot flow in loop 2, this kind flow phenomenon is stable folk prescription to flowing, and is only painstakingly limited and can flow towards the direction of design, can not violate arbitrarily flowing of design.Or allow and be full of liquid in the fluid Return Channel 24 to form fluid-tight, it can put full capillary structure fully to form fluid-tight in stream Return Channel 24, also can dwindle gas by the space to form fluid-tight, thereby make the fluid circulation more stable mobile towards design direction with the asymmetry that increases flow resistance, but can influence the trafficability characteristic of non-condensing gas at this moment because of liquid Return Channel 24, make its uniform temperature relatively poor.So can to eliminate non-condensing gas, improve uniform temperature by degasification program to loop 2.
Because loop 2 has been configured to tandem, and form sequential folk prescription to circulating, make the not concretive gas that is present in the loop 2 not gather the space and the time of stop, can only flow or condensate liquid stream flowing in loop 2 along steam flow, so the present invention can form the liquid and the not concretive gas of liquid stream after gas that steam channel 22 contains most of steam flow, the small part condensation in loop 2; Fluid Return Channel 24 spaces contain most of gas and not concretive gas for condensate liquid stream, small part steam flow, constitute apace folk prescription to circulating.Fluids all in the loop 2 is all flowed towards same direction, and not conflict mutually, and all fluids any time can both be by any pipeline in the system, so heat transfer property is good, hot biography amount is big, and has a narrow range of temperature.
When the present invention makes,, then need form different internal diameters if adopt the pipeline of same outer diameter as.The method that wherein forms different inner diameters forms big flow resistance and guides the capillary structure 26 that condensed fluid returns evaporation part 21 for being provided with in fluid Return Channel 24, the path of its internal diameter is diminished, it is big that flow resistance becomes, its length only reaches in the length of condensate liquid stream place fluid Return Channel 24, or extend to evaporation part 21 separately, or extend to condensation part 23 separately, or extend to evaporation part 21 and condensation part 23 simultaneously.Also can in steam channel 22, capillary structure be set, but must meet the condition of the flow resistance of steam channel 22 less than fluid Return Channel 23 flow resistances.
Capillary structure 26 is pottery, sintered powder, foaming metal, mesh grid, sintering net, channel form plate, fibre bundle or helix.
Wherein fluid Return Channel 24 need be provided with the space that allows steam and not concretive gas to pass through.
In sum, the present invention uses and constitutes steam channel 22 and the unequal tube-separating type structure of 24 flow resistances of fluid Return Channel, principles such as the pressure reduction that cooperation is produced, hot-fluid imbalance, capillarity, form tandem order folk prescription to the fluid loop structure, and steam channel 22 and fluid Return Channel 24 also can the parallel pipeline structures of each self-forming, as long as under the preceding topic of flow resistance in fluid Return Channel 24 greater than flow resistance in the steam channel 22, cooperate heat to pass the setting of piece 3 and contiguous block 4, just can produce connection cyclic loop 2.So, even pipeline of the present invention without the degasification program, also can be operated heat transfer in manufacturing process.If after the degasification program, then heat conductivity is better, and operating temperature range is wider.So, make loop 2 easier compositions, compare with known heat pipe on reality is used, the moving speed of its heat-conducting flow is good faster than the moving speed of the heat-conducting flow of known heat pipe, hot uniform temperature height, heat transmitting, and hot biography amount is greater and faster.So the present invention need not the degasification processing procedure, and also inessential to the clean process of cleaning, its processing procedure is simple, cost is low, price also can reduce thereby make, have better economy, functional better, usability is good.
The present invention forms multi-tube structure, it is series at evaporation part 21, steam channel 22, condensation part 23, fluid Return Channel 24 on the loop 2 in regular turn, steam channel 22 is a pair of pipeline, that is to say to be provided with single pipeline or the above steam channel that forms parallel connection of two pipelines; Fluid Return Channel 24 is for only establishing single pipeline, but also can establish two goes up to form fluid Return Channel in parallel, to form the connection in series-parallel framework, can be applicable to that the more efficient heat of generation passes switch, utilize the guide function of loop 2 flow resistances, thereby being had hardly, loop 2 of the present invention dryouies the phenomenon generation, so, under the confined space, can have and big heat biography amount to produce good heat transmitting; Asymmetric phenomenon of hot-fluid and guidance loop 2 in the utilization loop 2, make the present invention become circulation shape pipeline, existing not concretive gas 2 is constantly circulated along the loop, significantly improve uniform temperature of the present invention, so even not concretive gas is arranged in the loop 2, functional characteristic of the present invention is all influenced not quite, and can prolong service life of the present invention.
