Abstract
A kind of concentrated cooling circuit board, comprise substrate, described substrate covers one deck heating panel, described heating panel has at least one heat radiation protruding, described heating panel covers a layer circuit board, on described circuit board, corresponding position protruding with the heat radiation of described heating panel has thermal vias, the hole wall of thermal vias scribbles heat-conducting silicone grease, concentrated cooling circuit board of the present utility model can make the radiating efficiency of circuit board be greatly improved, and improve radiating efficiency by effectively reducing dust, and then greatly increase the useful life of circuit board.
Description
Technical field
The utility model relates to field of circuit boards, particularly relates to a kind of concentrated cooling circuit board.
Background technology
Circuit board generally can be arranged and be provided with several functions parts, when these functional part work, all produce large calorimetric, along with the further raising of current integrated technology, also harsher to the cooling requirements of circuit board.Current employing arranges heating panel under circuit board, on heating panel and circuit board, all have louvre simultaneously, although radiating effect increases, but due to the easy dust stratification of heat radiation Long-Time Service on collecting plate, radiating effect is caused to decline gradually, affect the useful life of circuit board, and the radiating efficiency of louvre is limited.
Utility model content
The utility model is the problems referred to above solving prior art existence, provides a kind of radiating efficiency and better concentrates cooling circuit board.
For achieving the above object, the utility model provides a kind of concentrated cooling circuit board, comprise substrate, described substrate covers one deck heating panel, described heating panel has at least one heat radiation protruding, described heating panel covers a layer circuit board, on described circuit board, corresponding position protruding with the heat radiation of described heating panel has thermal vias, and the hole wall of thermal vias scribbles heat-conducting silicone grease.
Further preferably, described heating panel has two heat radiations protruding, described circuit board has corresponding two thermal vias protruding with the heat radiation on described heating panel.
Further preferably, the material of described heating panel is aluminium alloy, brass or bronze, and one-body molded.
Further preferably, described heating panel has cavity, and it is protruding that this cavity extends to heat radiation, and be connected with cooling fluid in this cavity.
Further preferably, the height that described heat radiation is protruding is more than or equal to the thickness of heating panel.
Concentrated cooling circuit board of the present utility model, by comprising substrate, described substrate covers one deck heating panel, described heating panel has at least one heat radiation protruding, described heating panel covers a layer circuit board, on described circuit board, corresponding position protruding with the heat radiation of described heating panel has thermal vias, the hole wall of thermal vias scribbles heat-conducting silicone grease, the radiating efficiency of circuit board is greatly improved, and improve radiating efficiency by effectively reducing dust, and then greatly increase the useful life of circuit board.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment that the utility model concentrates cooling circuit board to provide;
Fig. 2 is the exploded view of Fig. 1.
Reference numeral:
1, substrate; 2, heating panel; 3, circuit board; 4, heat radiation is protruding; 5, thermal vias.
Embodiment
Below in conjunction with accompanying drawing 1 and accompanying drawing 2, concentrated cooling circuit board of the present utility model is described in detail.
As shown in Figure 1, Figure 2, concentrated cooling circuit board comprises substrate 1, described substrate 1 covers one deck heating panel 2, described heating panel 2 have two heat radiations protruding 4, described heating panel 2 covers a layer circuit board 3, position corresponding with the heat radiation projection 4 of described heating panel 2 on described circuit board 3 has two thermal vias 5, the hole wall of thermal vias 5 scribbles heat-conducting silicone grease, this embodiment makes the radiating efficiency of circuit board 3 be greatly improved, and improve radiating efficiency by effectively reducing dust, and then greatly increase the useful life of circuit board 3.
Be understandable that, the number of heat radiation projection 4, thermal vias 5 is more, and the heat radiation of circuit board 3 is better, but also can affect the area of circuit board 3, and therefore, the number of described heat radiation projection 4, thermal vias 5 comprehensively can be determined by designer.
In concrete enforcement, the material of described heating panel 2 can be aluminium alloy, brass or bronze, certainly the material of radiating effect can also be had for other, in addition, described heating panel 2 and its heat radiation of having protruding 4 one-body molded, the heat that circuit board 3 produces can better be allowed like this to pass to heating panel 2 and heat radiation protruding 4.
Preferably, in order to dispel the heat to circuit board 3 better, described heating panel 2 has cavity, and this cavity extends to heat radiation protruding 4, and is connected with cooling fluid in this cavity, and described cooling fluid regularly replaces by pump.
In concrete enforcement, the height of described heat radiation protruding 4 is more than or equal to the thickness of heating panel 2, and thermal vias 5 and protruding 4 interference fit of heat radiation.
Although the foregoing describe embodiment of the present utility model; but those skilled in the art are to be understood that; these only illustrate; various changes or modifications can be made to present embodiment; and not deviating from principle of the present utility model and essence, protection range of the present utility model is only defined by the appended claims.
