We will cherish every opportunity to cooperate with you and look forward to your consultation and cooperation, let us work together to create a better future! The company is the manufacturer, such as the need Fairchild inverter series, machine type, fan and pump type, frequency machine, water type, stop delay, track type and stone cutters and other models, you can contact me direct the Secretary customization, please consult the discussion! Fairchild Technology Co., Ltd. Shenzhen welcome your calls, enthusiasm for your service! Enterprise micro-channel public account: Fairchild Drive following a promotional article Normally, the drive is installed in the control cabinet. We need to understand one inverter heat is about how much you can use the following formula to estimate: calorific approximation = inverter capacity (KW) × 55 [W] here, if the inverter capacity is constant torque load Associate of (flow capacity 150% × 60s) If the drive has a DC reactor or AC reactor, and also cupboard, then the heat will be even greater. Reactor installed in the side or top of the test drive better. Then you can use to estimate: the inverter capacity (KW) × 60 [W] because each inverter manufacturers of hardware are similar, so the formula for the brand's products can Note: If you have a braking resistor, then, because the braking resistor The large amount of heat, so it is best to install the best location and the drive to isolate, as installed in the cabinets above or beside the like. So, how mining can reduce the heat in the control cabinet it? When the drive is installed in the control cabinet to consider the issue inverter heat values. According to increase the heat generated inside the enclosure value, should be appropriate to increase the size of the cabinet. Therefore, to make control the size of the cabinet to minimize heat value must be generated to make the cabinet to minimize. If at the time the drive is installed, the radiator portion of the inverter to the outside of the control cabinet, will have 70% of the inverter heat is released to the outside of the control cabinet. Due to the large capacity of the drive has a great amount of heat, so the more effective for large capacity drives. You can also use the body and the radiator isolation plates separated, so that the heat sink does not affect the inverter. This effect is also very good. Inverter cooling design is based on a vertical installation, put the heat will deteriorate sideways! Inverter cooling fan on the general power of slightly larger, are equipped with a cooling fan
