海上作业直升机载接收机必须采用密封机箱。机载设备的小型化和轻型化要求使其体积缩小,而功率要求不降反升,从而导致热流密度急剧上升。详细介绍了某直升机载接收机的热设计方法,并进行了热仿真和试验验证。通过优化热设计,为良好的热设计及提高其可靠性和使用寿命提供了保证。 Sea-going helicopter receivers must be sealed enclosures. The miniaturization and light-weight requirements of on-board equipment require that their size be reduced, while the power requirements rise and fall, resulting in a sharp rise in heat flux density. The thermal design method of helicopter receiver is introduced in detail, and the thermal simulation and experimental verification are carried out. By optimizing the thermal design, it provides a guarantee for good thermal design and increased reliability and service life.
