Abstract
The utility model discloses an inner and outer groove radiator structure. The inner and outer groove radiator structure is characterized by comprising a main body, revolving side walls, fins and a separation layer. The main body is a heat conduction container and provided with a containing space used for containing a driver and a top face matching with a light-emitting diode (LED) light source board. The revolving side walls are arranged around the top face. The fins are arranged around the side walls of the main body and stand on the outer surfaces of the side walls. The separation layer is connected on the outer surfaces of the side walls of the main body in a revolving mode and penetrates through all the fins. The fins are divided into inner fins and outer fins according to the radial direction of the main body, wherein the separation layer and two adjacent fins form an inside groove state and an outside groove state. According to the inner and outer groove radiator structure, original depths of an outer groove can fill an inner groove, spraying effect of the surface of the outer groove can be ensured, and the situation of spraying failure due to the fact that grooves are deep is avoided. Meanwhile, sizes of the radiating fins are not changed, heat volume is not changed, and therefore good radiating effect can be achieved.
Description
Technical field
The utility model relates to a kind of interior its structure of water jacket radiator for the LED spheric bulb.
Background technology
Led light source has obtained using more widely as the replacer of globular bulb.More common form wherein is that the cell-shell in its top is plugged into the radiator of trunk to lamp holder.This class spreader surface often deals with on its surface in order to realize better thermal convection current radiating effect, enlarges its effective area: add protrusions such as increasing radiating groove, fin, make the radiator of equal volume, its surface can possess maximum to flow area.
The implementation that this class is processed is a lot, for example directly casts out complete radiator, and its surface has a plurality of to chute; Adopt extrusion molding person, its outer surface has fin, and perhaps a plurality of assembling parts formulas are directly assembled moulding.No matter which kind of mode, for obtaining suitable radiating effect, its groove shape structure is often deep, if need to deal with on the surface of groove shape structure, for example sprays paint, and its groove shape structure will inevitably restrict the surface effect that sprays paint so.
The utility model content
For can the spray paint present situation for the treatment of effect of existing groove shape structure radiator, the utility model proposes a kind of structure of interior water jacket radiator, its technical scheme is as follows:
A kind of structure of interior water jacket radiator, it comprises:
Main body is a thermal conductive container, have one can accommodating driver accommodation space and can be matched with the end face of led light source plate; Has rotating sidewall around this end face;
Fin around the sidewall distribution of this main body, stands on this sidewall outer surface; And
Interlayer, revolution is connected in the outer surface of this main body wall, and passes all these fins; This fin radially is divided into interior fin and outer-finned two parts by main body; Wherein this interlayer and adjacent two these fins form the form of an inside groove and water jacket.
As the scheme of some improvement, the embodiment of following aspect can be arranged:
In the better embodiment, the form that this interlayer and main body are communicated as one away from an end of end face in this main body.
In the better embodiment, this water jacket is connected with free space at this summit portion.
In the better embodiment, this main body, this fin arrange with respect to the central axis Rotational Symmetry of this end face.
In the better embodiment, the accommodation space of this body interior is a cylindrical shape.
In the better embodiment, this water jacket begins along body shaft to shrinking gradually from described end face.
In the better embodiment, the cast member that this radiator is formed in one.
The beneficial effect that the utility model brings is:
1. the original degree of depth of water jacket will be subject to the inside groove filling, and the spraying effect of its outer rooved face can be guaranteed, no longer because groove is taken an advanced study into very much the situation that spraying was lost efficacy.The size of radiator fins does not change simultaneously, and thermal capacitance is long-pending constant, can have good radiating effect.
2. this main body comprises end face, sidewall and fin, and all the central axis Rotational Symmetry with respect to this end face arranges, and so makes radiation effect of fin symmetrical and even, and integral body is convenient to processing simultaneously.
3. the accommodation space of this body interior is a cylindrical shape, and this water jacket begins along body shaft to shrinking gradually the depanning processing when so being beneficial to casting from end face.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Fig. 1 is the axle generalized section of the utility model one embodiment;
Fig. 2 is AA phantom embodiment illustrated in fig. 1;
Fig. 3 is schematic perspective view embodiment illustrated in fig. 1.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, the schematic diagram of an embodiment of the present utility model: a kind of structure of interior water jacket radiator, this radiator is used for the trunk of a bulb lamp, the cast member that is formed in one:
It comprises a main body, and this main body is a thermal conductive container, have one can accommodating driver accommodation space 16 and can be matched with the end face 18 of led light source plate; Has rotating sidewall 17 around this end face 18; Be provided with fin and interlayer 13 in the periphery of main body wall 17.Interlayer 13 is that revolution is connected in the outer surface of this main body wall 17, and passes all fins, with this fin by radially being divided into of main body interior fin 15 and outer-finned 11 two parts; Wherein this interlayer 13 and two adjacent these fins form the form of an inside groove 14 and water jacket 12.
In Fig. 2 as seen, so-called water jacket 12, the convection current flute profile attitude of the be directly used in heat exchange that namely directly is communicated with space outerpace; Inside groove 14 is between interlayer 13 and sidewall 17, and major part directly is not exposed to space outerpace.So, water jacket 12 original degree of depth will be subject to inside groove 14 and fill, and the spraying effect on its water jacket 12 surfaces can be guaranteed, no longer because groove is taken an advanced study into very much the situation that spraying was lost efficacy.The size of radiator fins does not change simultaneously, and thermal capacitance is long-pending constant, can have good radiating effect.When end face 18 no longer is that the part of inside groove 14 also can be finished heat exchange with free space when covering led light source plate (not indicating) fully.
In the present embodiment, this interlayer 13 and main body away from the form that an end of end face 18 is communicated as one, make its whole external diameter gradual change trend towards the shape of globular bulb in this main body, can have less volume; This main body comprises end face 18, sidewall 17 and fin, and all the central axis Rotational Symmetry with respect to this end face 18 arranges, and so makes radiation effect of fin symmetrical and even, and integral body is convenient to processing simultaneously.The accommodation space 16 of this body interior is a cylindrical shape, and this water jacket 12 begins along body shaft to shrinking gradually the depanning processing when so being beneficial to casting from end face 18.
The above, it only is the utility model preferred embodiment, so can not limit according to this scope that the utility model is implemented, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
