Abstract
The utility model relates to a heat dissipation type metal circuit box which comprises a metal circuit box body. The utility model is characterized in that: the metal circuit box body is provided with a heat dissipation window; and the heat dissipation window is internally provided with heat dissipation fins. Furthermore, a contact surface of the heat dissipation fins is provided with a circuit board base which is provided with a circuit board whereon. Therefore, the heat generated by the circuit board is eliminated and transferred through the matching of the heat dissipation fins and the metal circuit box body. Not only can heat be dissipated by the metal circuit box body, but also the area of each heat dissipation fin can be effectively reduced, and the manufacturing cost of the heat dissipation fin can be reduced. Furthermore, the scratching of the fin in the heat dissipation fins to other component can be prevented through the existence of extending edge.
Description
Technical field
The utility model relates to a kind of circuit box, relates in particular to a kind of heat dissipation type metallic circuit box.
Background technology
In field of household appliances, go up especially on air-conditioning, along with the development of converter technique, increasing product is brought into use converter technique, and transistor uses on circuit in a large number as a kind of adjusting power supply components and parts.Transistor can produce a large amount of heats at work, in order to guarantee its job stability, need take away the heat of its generation, and the normal fin that uses is taken away its heat in the circuit.Circuit box can prevent that as the fixing pedestal of electronic circuit board circuit is damaged by external force, guarantees the product operate as normal.Consider the not flammable, firm in structure of metal, and the convenience of making, circuit box often is made for the monolithic metal punching press at present.Present circuit box structure has following two shortcomings: 1) the fin volume is big relatively, takies product space; 2) material cost height, product competitiveness is little.
The utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of heat dissipation type metallic circuit box is provided.
For realizing the purpose of this utility model heat dissipation type metallic circuit box, include the metallic circuit box body, wherein: offer thermal window on the described metallic circuit box body, be provided with fin in the described thermal window; The circuit board base is installed on the contact-making surface of described fin, and described circuit board base is provided with circuit board.
Further, above-mentioned heat dissipation type metallic circuit box wherein, is provided with leading backing between the contact-making surface of described fin and the circuit board.
Further, above-mentioned heat dissipation type metallic circuit box, wherein, described fin periphery is provided with the extension sheet, is provided with secondary conducting strip between extension sheet and the thermal window.
Again further, above-mentioned heat dissipation type metallic circuit box, wherein, described thermal window is provided with extension edge outward, and the fin height of described fin is lower than the height of extension edge.
Adopt technical solutions of the utility model, by the common heat that cooperate dissipate transfer circuit plate produce of fin with the metallic circuit box body, can either allow the metallic circuit box body heat that dissipates, can effectively reduce the area of fin again, reduce the manufacturing cost of fin.And, can be by the existence of extension edge, avoid the fin of the fin miscellaneous part that scratches.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the side profile construction schematic diagram of heat dissipation type metallic circuit box;
Fig. 2 is a heat dissipation type metallic circuit box explosive decomposition schematic diagram.
The implication of each Reference numeral is as follows among the figure:
1 metallic circuit box body, 2 thermal windows
3 fin, 4 circuit board bases
5 circuit boards, 6 leading backings
7 extension edges, 8 secondary conducting strips
9 extension sheets
Embodiment
Heat dissipation type metallic circuit box as shown in Figure 1 and Figure 2 includes metallic circuit box body 1, and its special feature is: offer thermal window 2 on the described metallic circuit box body 1, be provided with fin 3 in the described thermal window 2.By the cooperation of thermal window 2, can effectively hold fin 3, avoid fin 3 because of the air thermal resistance that out-of-flatness produces is installed.Simultaneously, circuit board base 4 is installed on the contact-making surface of described fin 3, on circuit board base 4, is provided with circuit board 5.
In conjunction with the utility model one preferred implementation, the heat that produces for the ease of circuit board 5 can be comparatively fast and intactly is delivered on the fin 3, is provided with between the contact-making surface of fin 3 and circuit board 5 and dominates backing 6.Simultaneously, in order to allow metallic circuit box body 1 cooperate further with fin 3, allow metallic circuit box body 1 also disperse the heat that fin 3 has, the periphery of the fin 3 that the utility model adopted is provided with extension sheet 9, is provided with secondary conducting strip 8 between extension sheet 9 and the thermal window 2.Thus, cooperates with heat transferred between the secondary conducting strip 8 by leading backing 6, the heat that circuit board 5 work can be produced carries out the dissipation of the best by fin 3 and metallic circuit box body 1.
And, in order not allow the fin of fin 3 influence other parts of heat dissipation type metallic circuit box periphery, outside thermal window 2, being provided with extension edge 7, the fin height of described fin 3 is lower than the height of extension edge 7.Like this, can effectively avoid the fin of fin 3 miscellaneous part that scratches.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, after adopting the utility model, by the common heat that cooperate dissipate transfer circuit plate produce of fin with the metallic circuit box body, can either allow the metallic circuit box body heat that dissipates, can effectively reduce the area of fin again, reduce the manufacturing cost of fin.And, can be by the existence of extension edge, avoid the fin of the fin miscellaneous part that scratches.
Certainly, more than only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
