Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one: a kind of manufacture method of phase-change radiator
Shown in accompanying drawing 1, a kind of manufacture method of phase-change radiator, described phase-change radiator comprises radiator body 2, end cap 1 and the mount pad 3 in order to install heater element.The structure of radiator body 2 is substantially identical with prior art, has the cylindrical shell of a metal, and this metal cylinder is outward extended with multiple radiating fin 4.Mount pad 3 generally adopts the Heat Conduction Material such as copper, aluminium to make, conduction be arranged on heater element (light emitting diode as LED lamp) on mount pad produce heat to phase-change material.Described radiator body 1 offers through hole, and the cross sectional shape of through hole can be arbitrary shape.
When making:
First described end cap 1 is arranged on one end of the through hole of described radiator body 2, adopt the method for the friction welding (FW) in solder technology to implement herein in the present embodiment, the mode of existing solder technology or elastic conjunction can be adopted in other detailed description of the invention.Then in through hole, inject liquid state phase change material and steam state phase-change material, the object adding steam state phase-change material is to drive the air be present in through hole.Mount pad 3 is assemblied in the other end of through hole by the mode of following employing elastic conjunction.Thus define the inner airtight inner chamber only accommodating phase-change material.Liquid state phase change material 6 and steam state phase-change material 7 add order in no particular order.
In order to prevent in the fit tolerance assembling in the end stage, air enters through hole, and best embodiment is: described elastic conjunction carries out under steam state phase-change material atmosphere.
Shown in accompanying drawing 2 ~ 6, better embodiment is: mount pad 3 is evenly equipped with multiple protruding 5 towards the surface of described through hole, and the quantity of protruding 5 determines according to the area of mount pad 3, and the larger projection of area is more.Theoretical according to pool boiling, projection plays an important role to the raising of the evaporation rate of the phase-change material in through hole, but only has when projection exposes the liquid level of liquid state phase change material 6, and protruding 5 could wield influence to the evaporation rate of phase-change material.Theoretical according to pool boiling, the evaporation rate impact of protruding shape on phase-change material is little, the present invention considers from being convenient to process protruding angle, be cylindric by the profile design of described projection in one embodiment, in the embodiment of another difference slightly, add convex ball on the top of described columned projection.Be Pyramid by the profile design of described projection in another detailed description of the invention.
When radiator body horizontal positioned, because liquid state phase change material 6 is laid in mount pad 3, when being designed to consistent by the height of protruding 5, all projections 5 all can wield influence to the evaporation rate of phase-change material.
When radiator body slant setting, if when the height of protruding 5 is designed to consistent, the projection 5 that so existence part is covered completely by liquid state phase change material, this part projection does not play any impact by the evaporation rate of phase-change material.
In further preferred embodiment, be designed to highly inconsistent by described protruding 5, though like this radiator body 2 slant setting time, still have part projection 5 to be positioned on the liquid level of liquid state phase change material 6, and the evaporation rate of phase-change material wielded influence.
Better embodiment is the height be designed to by the height of the projection 5 of the middle section of described mount pad 3 lower than described mount pad 3 peripheral regions.When such radiator body 2 is to unspecified angle slant setting, still has part projection 5 to be positioned on the liquid level of liquid state phase change material 6, and the evaporation rate of phase-change material is wielded influence.
Better embodiment is designed to by the height of described projection be increased gradually by the surrounding of mount pad 3 described in the mediad of described mount pad 3.The projection exposing the liquid level of liquid state phase change material is like this more.
Better embodiment is designed to by the height of described projection be increased gradually by the opposite side of the side of described mount pad 3 to described mount pad 3.When such radiator body is placed to lopsidedness, a large amount of projections is had to be positioned on the liquid level of liquid state phase change material.
Better embodiment is the height height of the projection of the side of described mount pad 3 being designed to the projection higher than described mount pad 3 opposite side.
Elastic conjunction can adopt existing technical scheme.Elastic conjunction occupies critical role in engineering goods assembling process, and Application comparison is extensive.Interference fit is exactly by external member (hole) mount pad on internal member (axle), when external member restores, produces the tightening force to internal member, and two parts are connected.Specifically comprise press-in assembling method, low temperature assembling method and heating assembling method.Adopt the immense pressure that press and hydraulic press produce in the present embodiment, by the press-in of the termination of mount pad 3 in the through hole of radiator body 2.Low temperature assembling method and heating assembling method are the performances of expanding with heat and contract with cold utilizing material, the mount pad 3 of interference fit is dropped to uniform temperature, or radiator body 2 is heated to uniform temperature, thus interim eliminate the through hole of radiator body 2 and the magnitude of interference of mount pad 3, then rapid mount pad 3 and radiator body 2 to be assembled together.
Embodiment two: a kind of manufacture method of phase-change radiator
Difference between the method that embodiment two adopts and the method that embodiment one adopts is only, adopt the method for welding to be arranged on one end of the through hole of radiator body 2 to by mount pad 3, then adopt the mode of elastic conjunction end cap 1 to be assembled to the other end of through hole to form the airtight phase-change material container cavity being used for holding phase-change material.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
