Description
Technical field
The present invention relates to modular power source, the modular power source that particularly a kind of thermal diffusivity is good.
Background technology
Along with the develop rapidly of microelectric technique, DC-DC module power source is widely used in the communications fields such as switching equipment, access device, mobile communication, microwave communication, optical transport, router, and the field such as automotive electronics, Aero-Space.In use, system, according to the operating voltage of circuit, is selected the number of coupling DC-DC module power source, is grouped together by multiple DC-DC module power source, forms the power module that power density is high, conversion efficiency is high, its compact conformation.Therefore, the power consumption of electronic device module is increasing, and traditional air-cooled technology can not meet the radiating requirements of module.
Existing modular power source adopts the mode of air cooling or liquid cooling to dispel the heat to modular power source internal structure mostly, but these two kinds of modes all need additionally to increase cooling structure, cause modular power source volume to increase, this is for a huge strike beyond doubt the very high modular power source of integration level necessitates.
In addition, when modular power source is assembled, housing is connected by rivet post with cover plate, namely on housing corner, rivets a rivet post respectively, cover plate covers on housing, and be riveted into one by rivet and rivet post, but in actual production process, when carrying out riveting process, rivet post there will be rotation phenomenon on housing, cause riveted joint loosely, even rivet post and housing coupling part divide fracture, cause housing to be scrapped.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of and prevent the modular power source that guide pile rotates, reliable and stable and that circuit board can the be prevented anti-loaded thermal diffusivity of circuit board is good.
Object of the present invention is achieved through the following technical solutions: the modular power source that a kind of thermal diffusivity is good, it comprises housing, circuit board body and cover plate, the two sides of described circuit board body is provided with multiple heating element, described housing is the box body structure of upper opening, multiple groove and conduction aluminum strip is provided with bottom case inside, circuit board body is arranged on case inside, the ledge of heating element is embedded in inside grooves, conduction aluminum strip top is pressed on the side of circuit board body, the corner of case inside is also provided with boss, boss and housing one-body molded, each boss internal fixtion is provided with guide pile, guide pile runs through boss and housing bottom is arranged, described housing has step surface along inside upper part edge, and cover plate covers on step surface, and is fixedly connected with guide pile by screw.
The height of described boss is higher than the height of conduction aluminum strip.
The corner of described circuit board body offers breach, breach respectively with the side clamping of boss.
The length of fit of described guide pile and boss and housing is greater than the guide pile length above boss.
Also laminating between described groove and heating element have heat conductive silica gel.
The present invention has the following advantages:
1, groove is offered in enclosure interior, heating element on circuit board is all embedded in inside grooves, the outer surface of heating element and groove contact area are increased, efficiently radiates heat area increases, improve radiating effect, heat conductive silica gel is set between groove and heating element, strengthens the radiating effect of power shell further.
2, at boss internal fixtion, guide pile is installed, guide pile runs through boss and housing bottom is arranged, and the length of fit of guide pile and boss and housing is greater than the guide pile length above boss, guide pile and the mating surface between housing and boss increase, the frictional force that guide pile is subject to housing and boss increases, guide pile not easily rotates, thus makes the connection between housing and cover plate more firm.
3, the corner of circuit board arranges breach, with boss clamping, circuit board is arranged on enclosure interior and is more fixed reliably, and conduction aluminum strip top pressure on circuit boards, position relationship between the circuit board element of conduction aluminum strip both sides and conduction aluminum strip is fixed, prevent in use, circuit board is given a shock and is shifted, thus makes modular power source more reliable and more stable.
4, heat radiation elements and groove are all one-to-one relationships, if fill counter for circuit board, then cannot load in groove by heat radiation elements, only have correct mounting circuit boards heat radiation elements and groove corresponding matching could be installed, play the effect preventing circuit board anti-loaded.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, but protection scope of the present invention is not limited to the following stated.
The modular power source that a kind of thermal diffusivity is good, it comprises housing 1, circuit board body 2 and cover plate 3, as shown in Figure 4, the two sides of described circuit board body 2 is provided with multiple heating element 9, as Fig. 1, shown in Fig. 2 and Fig. 3, described housing 1 is the box body structure of upper opening, housing 1 inside bottom is provided with multiple groove 4 and conduction aluminum strip 5, circuit board body 1 is arranged on inside housing 1, the ledge of heating element 9 is embedded in groove 4 inside, conduction aluminum strip 5 top is pressed on the side of circuit board body 2, corner inside housing 1 is also provided with boss 7, boss 7 is one-body molded with housing 1, each boss 7 internal fixtion is provided with guide pile 8, guide pile 8 runs through setting bottom boss 7 and housing 1, described housing 1 has step surface 6 along inside upper part edge, and as shown in Figure 5, cover plate 3 covers on step surface 3, and is fixedly connected with guide pile 8 by screw.
Further, the height of described boss 7, higher than the height of conduction aluminum strip 5, the corner of described circuit board body 2 offers breach 10, breach 10 respectively with the side clamping of boss 7.
