Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, device for controlling power tool, shell 1 and setting including internal cavity structure are described outer
Wiring board 2 inside shell 1, shell 1 are the box body structure of rectangle, and shell includes upper cover 21 and lower casing 20, and the upper cover 21 passes through
Several screws 22 lock on the side wall of the open side of lower casing, and line outlet 19 is offered on the wall body of lower casing, the shell 1
Be provided with several mounting structures 5 on inner sidewall, the mounting structure 5 is used for fixing circuit board 2, the inner wall of the shell 1 with
Be provided with heat-conducting plate 4 between wiring board 2, the heat-conducting plate 4 contacts setting with shell 1 and wiring board 2 respectively, the shell 1 with
Radiating groove 6 is offered in the opposite outside wall surface of heat-conducting plate 4, as shown in Fig. 5, the radiating groove 6 is recessed in shell lateral surface
On several strip groove-like structures, on the one hand can reduce the wall thickness of shell, on the other hand can make the cord shape between radiating groove
At radiating fin, increase heat-conducting plate between shell and wiring board by increasing, by heat-conducting plate to the heat in shell inner cavity
Be thermally conducted on housing wall, and radiated by radiating groove, the further radiating efficiency for promoting wiring board guarantees wiring board
Normal work.
The set-up mode of heat-conducting plate includes two ways, and one is the heat-conducting plates 4 to contact the power on setting wiring board 2
Device, can be quick by the direct thermal contact conductance to power device since the component to generate heat on wiring board is mainly power device
Reduce power device on heat, guarantee radiating efficiency.Another embodiment is that the heat-conducting plate 4 is insulator-metal board,
And the heat-conducting plate 4 contacts setting with the bottom copper foil on wiring board 2, wherein bottom copper foil refer on wiring board with power device
The copper foil of opposite another side namely soldering spot area, since bottom copper foil is also the route of super-high-current, by bottom
The contact of copper foil is radiated, and the sheet metal of improving heat radiation efficiency, preferably surface insulation processing, the heat transfer efficiency of metal plate is preferable,
Heat-transfer rate is fast, is handled by surface insulation, avoids influence of the heat-conducting plate to the last solder joint of wiring board.
As shown in attached drawing 2 to attached drawing 4, wherein mounting structure in the prior art 5 is the mode of bolt, namely directly pass through
Several screws directly lock wiring board on the inner wall of shell, need to dismount multiple screws when assembly, more numerous
