Embodiment
Below in conjunction with Figure of description, the technical solution of the utility model is described in further detail.
As shown in Figure 1, pcb board comprises first circuit board 1, second circuit board 2, described second circuit board 2 is provided with switching power circuit, power circuit, PIM module 7, slot, described first circuit board 1 is provided with main control chip, due on first circuit board 1 with main control chip, and system includes High-frequency Interference, therefore need to design in anti-interference, first circuit board 1 and second circuit board 2 are by the mutual at right angle setting of connector and position is selected from the place away from switching power circuit 9 and power circuit 8, the High-frequency Interference of switching power circuit 9 can be avoided like this and prevent big current from scurrying into main control loop.
As shown in Figure 2,3, the special variable-frequency motor of integral blower comprises blower motor 3, described blower motor 3 comprises rear end cap 5, covers in the motor back cover 4 of rear end cap 5 outward, and described rear end cap 5 forms pcb board container cavity with motor back cover 4, and the pcb board of frequency converter is arranged in pcb board container cavity.
Power device in second circuit board 2---PIM module 7 is high power consumption components and parts; as there is no good radiator structure; in a few minutes, temperature can reach more than 100 degree, as long-time running can cause PIM7 module overheated, thus carries out overtemperature protection even aircraft bombing.Therefore PIM module 7 is arranged on the back side of second circuit board 2, and the rear end cap 5 being close to blower motor 3 is installed, and middle painting last layer heat-conducting silicone grease, makes can carry out better heat trnasfer between the two, be beneficial to heat radiation.The wind of the high strength of blower fan generation simultaneously carries out air-cooled effect to motor housing, and motor housing temperature reduces the temperature also indirectly reducing circuit board, ensure that system stability runs reliably.
