具体实施方式 Detailed ways
以下结合说明书附图对本实用新型的技术方案做进一步的详细说明。 The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings of the description.
如图1所示， PCB板包括第一电路板1、第二电路板2，所述的第二电路板2上设有开关电源电路、功率电路、PIM模块7、插槽，所述的第一电路板1上设有主控芯片，由于第一电路板1上带有主控芯片，且系统包含有高频干扰，因此需要在抗干扰方面进行设计, 第一电路板1与第二电路板2通过接插件相互垂直安装且位置选择在离开关电源电路9和功率电路8较远的地方，这样可以避免开关电源电路9的高频干扰和防止大电流窜入主控回路。 As shown in Figure 1, the PCB board includes a first circuit board 1 and a second circuit board 2, and the second circuit board 2 is provided with a switching power supply circuit, a power circuit, a PIM module 7, and a slot. A circuit board 1 is provided with a main control chip. Since the first circuit board 1 has a main control chip and the system contains high-frequency interference, it is necessary to design anti-interference. The first circuit board 1 and the second circuit The boards 2 are installed perpendicular to each other through the connectors and the position is selected at a place far away from the switching power supply circuit 9 and the power circuit 8, so as to avoid the high-frequency interference of the switching power supply circuit 9 and prevent large currents from entering the main control circuit.
如图2、3所示，一体式风机专用变频电机包括风机电机3，所述的风机电机3包括后端盖5、外罩于后端盖5的电机后罩4，所述的后端盖5与电机后罩4形成PCB板容纳腔，变频器的PCB板位于PCB板容纳腔中。 As shown in Figures 2 and 3, the integrated fan-specific frequency conversion motor includes a fan motor 3, and the fan motor 3 includes a rear end cover 5, a motor rear cover 4 that is covered on the rear end cover 5, and the rear end cover 5 A PCB board accommodating cavity is formed with the motor rear cover 4, and the PCB board of the frequency converter is located in the PCB board accommodating cavity.
第二电路板2中的功率器件——PIM模块7是一个高功耗元器件，如没有良好的散热结构，几分钟内温度可以达到100度以上，如长期运行会导致PIM7模块过热，从而进行过热保护甚至炸机。因此PIM模块7安装在第二电路板2的背面，紧贴风机电机3的后端盖5安装，中间涂上一层导热硅脂，使两者之间可以进行更好的热传递，利于散热。同时风机产生的高强度的风对电机外壳进行风冷作用，电机外壳温度降低也间接的降低了电路板的温度，保证了系统稳定可靠的运行。 The power device in the second circuit board 2—the PIM module 7 is a high power consumption component. If there is no good heat dissipation structure, the temperature can reach more than 100 degrees in a few minutes. If it runs for a long time, it will cause the PIM7 module to overheat, thereby Overheating protection and even frying machine. Therefore, the PIM module 7 is installed on the back side of the second circuit board 2, and is installed close to the rear end cover 5 of the fan motor 3, and a layer of heat-conducting silicone grease is coated in the middle, so that better heat transfer can be carried out between the two, which is beneficial to heat dissipation . At the same time, the high-intensity wind generated by the fan cools the motor casing, and the temperature reduction of the motor casing also indirectly reduces the temperature of the circuit board, ensuring the stable and reliable operation of the system.
为了实现电机与PCB板之间的绝缘,第二电路板2通过螺丝和塑料的绝缘柱6安装在风机电机3的后端盖5上。电机后罩4罩在电路板上面，通过与风机电机3后端盖5的尺寸配合，可以达到IP55的防护等级，在室外安装也没有问题。 In order to realize the insulation between the motor and the PCB board, the second circuit board 2 is installed on the rear end cover 5 of the blower motor 3 through screws and plastic insulating posts 6 . The motor rear cover 4 is covered on the circuit board, and by matching with the size of the fan motor 3 rear end cover 5, the protection level of IP55 can be achieved, and there is no problem in outdoor installation.
以上图1、2、3所示的一种一体式风机专用变频电机用PCB板安装结构是本实用新型的具体实施例，已经体现出本实用新型实质性特点和进步，可根据实际的使用需要，在本实用新型的启示下，对其进行形状、结构等方面的等同修改，均在本方案的保护范围之列。 The PCB board installation structure for an integrated frequency conversion motor for fans shown in Figures 1, 2, and 3 above is a specific embodiment of the utility model, which has already reflected the substantive features and progress of the utility model, and can be used according to actual needs. , under the enlightenment of the present utility model, equivalent modification of its shape, structure and other aspects are all within the scope of protection of this scheme.
