Description
Technical field
The present invention relates to a kind of electronic installation, particularly a kind of inductance element that is applied in the electronic installation.
Background technology
Inductance element is widely used in electronic installation because of the impurity that has in the filter current with the effect of stabling current; In computer equipment; Change issuable electromagnetic interference because of electric current to reduce electronic component when the running, stablize the service behaviour of electronic product.Traditional inductance element generally comprises a hollow housing, is located at the interior iron core of housing, reaches a substrate that is connected with housing.Wherein, this housing is cube shaped, and its outer surface is the plane.Because inductance element can produce heat when work, these heats are dispersed in the system via the outer surface of housing, and therefore, the quality of the radiating effect of inductance element depends on the surface area of its housing.Therefore, in order to increase the radiating efficiency of inductance element, industry adopts the surface area that increases housing through the mode of the size that increases housing, but this disagrees towards short and small frivolous development trend with electronic installation now again.
Summary of the invention
In view of this, be necessary to provide a kind of electronic installation that under the prerequisite of the size that does not increase inductance element, improves the inductance element of its radiating efficiency and use this inductance element.
A kind of inductance element comprises a housing, is located at the winding unshakable in one's determination in the housing and is incorporated into the substrate on this housing, at least one outer surface concave-convex surface of this housing.
A kind of electronic installation; Comprise a casing, be contained in a fan and the circuit board in the casing and be located at the inductance element on the circuit board; The air-flow that this fan produces blows to this inductance element; This inductance element comprises a housing, be located at the winding unshakable in one's determination in the housing and be incorporated into a substrate of this housing bottom, at least one outer surface concave-convex surface of the housing of this inductance element.
Because the outer surface concave-convex surface of the housing of this inductance element has increased the surface area of this inductance element, thereby has increased the area of dissipation of this inductance element under the prerequisite of the size that does not increase this inductance element, promote the radiating efficiency of this inductance element.

See also Fig. 1, the electronic installation 100 in one embodiment of the invention comprises a casing 10, be located at plurality of fans 20 on the casing 10, be located at the circuit board 30 in the casing 10 and be located at four inductance elements 40 on the circuit board 30.
For clearly illustrating the internal structure of this electronic installation 100, only show the base plate 12 of this casing 10 among this figure and perpendicular to the side plate 14 of this base plate 12.This circuit board 30 is located on this base plate 12.Also be provided with some other electronic components (not label) on this circuit board 30.This fan 20 is embedded on this side plate 14, and these several fans 20 are arranged in a row along the direction that is parallel to base plate 12.Produce air-flow during 20 work of this fan and blow to the heat that this inductance element 40 and other electronic components are produced when taking away these electronic components operations.
Please consult Fig. 2 simultaneously.Because Fig. 2 is the three-dimensional exploded view of inductance element 40 under inversion state, therefore, the description to inductance element 40 in the literary composition will be with its user mode, and promptly the direction among Fig. 1 is as the criterion.
This inductance element 40 comprises a housing 42, be contained in the winding 44 unshakable in one's determination in this housing 42 and be incorporated into a substrate 46 of these housing 42 bottoms.
It is cube shaped that the outside of this housing 42 roughly is; Its central authorities form a cylindrical accepting hole 420 vertically and are used to accommodate said winding unshakable in one's determination 44; Thereby this accepting hole 420 runs through the bottom surface 421 of this housing 42 forms an opening 422 in the bottom surface 421 of this housing 42, is used for supplying and should gets into this accepting hole 420 by iron core winding 44.The end face 423 of this housing 42 and with the parallel left-hand face 424 and right lateral surface 425 concave-convex surfaces of direct of travel of the air-flow of fan 20.Particularly, this end face 423 is formed with some grooves that are parallel to each other 426 equally spacedly, forms a raised line 427 between the two adjacent grooves 426.This groove 426 is parallel to each other with raised line 427 and is arranged alternately.These grooves 426 all extend along the direct of travel of air-flow with raised line 427.Similarly, also all form said groove 426 and raised line 427 on the left-hand face 424 of this housing 42 and the right lateral surface 425, these grooves 426 and raised line 427 all are parallel to the direct of travel of the air-flow of fan 20.
This iron core winding 44 comprises an iron core 442 and is wound in the coil 444 on unshakable in one's determination 442.This iron core 442 roughly is column, and the diameter at its middle part vertically is less than the diameter at two ends.This iron core 442 cross section vertically is greatly to being " worker " font.This coil 444 is wound in the middle part of this iron core 442.This iron core winding 44 has several line ends 446, and in the present embodiment, the quantity of this line end 446 is four.
This substrate 46 comprises the plate-like body that is square 462 and four pins 464 that are convexly equipped with from these body 462 bottom surfaces, and the central authorities of this body 462 form a through hole 460.These four pins 464 lay respectively at four corners of this body 462 and are provided with perpendicular to this body 462.
During assembling, this iron core winding 44 is contained in the accepting hole 420 of this housing 42, and this substrate 46 is incorporated into the end that this housing 42 has opening 422.The pin 464 of this substrate 46 deviates from this housing 42.Four line ends 446 of this iron core winding 44 pass the through hole 460 of this substrate 46 and are connected with these four pins 464 respectively.These four pins 464 are electrical connected with circuit board 30.
In this inductance element 40,, increased the surface area of housing 42, thereby increased the radiating efficiency of inductance element 40 because groove 426 and raised line 427 on end face 423, left-hand face 424 and the right lateral surface 425 of housing 42 are arranged alternately; Simultaneously, because this groove 426 extends with the direct of travel of raised line 427 along air-flow, can make airflow smooth ground blow over the surface of housing 42, and take away the heat on housing 42 surfaces effectively.In addition, the end face 423 of this housing 42, left-hand face 424, right lateral surface 425 are same postscript die face, and therefore, 426 disposable die sinkings of need of the groove on these three surfaces 423,424,425 just can form, manufacturing cost that can extra increase inductance element 40.
In the present embodiment, this groove 426 is formed at end face 423, left-hand face 424 and right lateral surface 425, during practical implementation; Can select to be provided with the surface of groove 426 according to airflow direction; In addition, for increasing radiating effect, can all offer groove at each outer surface of housing 42; Promptly on the front surface of housing 42 and surface, back, groove is set also, thereby further increases the radiating efficiency of inductance element 40.Certainly, what of surface that groove is set can depend on the circumstances, and also can only be arranged at 42 1 surfaces of housing such as groove, like end face 423 or left-hand face 424 or right lateral surface 425.
