具体实施方式detailed description
具体实施方式一：结合图1说明本实施方式，本实施方式所述的一种具有通风降温功能的雷达天线罩，其雷达天线罩上开有送风口(1)和出风口(2)，所述送风口(1)内设置有送风机(3)，所述雷达的天线阵面上设置有风冷设备(4)。Specific embodiment one: this embodiment is described in conjunction with Fig. 1, a kind of radome with ventilation cooling function described in this embodiment, has air supply port (1) and air outlet (2) on its radome, so An air blower (3) is arranged in the air outlet (1), and an air cooling device (4) is arranged on the antenna front of the radar.
如图1所示，送风机(3)将雷达天线罩外部的空气送进雷达天线罩内部，雷达天线罩内部的空气从出风口(2)流出，促进了雷达天线罩内整体的气流流动，带走雷达天线罩内散发的热量，降低了雷达天线罩内的温度。天线阵面的背面安装了风冷设备(4)，风冷设备(4)包括一块背板设置在背板上的蛇形通风管道，风冷设备(4)下方设置有风机，风机将空气吹入蛇形通风管道。当罩外冷空气掠过雷达表面时，利用该风机实现风冷设备表面气流的强制循环，加速对流散热，减少雷达后部由于处于通风背风侧而带来的局部热量累积。As shown in Figure 1, the air blower (3) sends the air outside the radome into the inside of the radome, and the air inside the radome flows out from the air outlet (2), which promotes the overall air flow in the radome, with The heat dissipated in the radome is taken away, reducing the temperature in the radome. Air-cooling equipment (4) is installed on the back side of the antenna array. The air-cooling equipment (4) includes a serpentine ventilation duct with a backboard arranged on the backplane. A fan is arranged under the air-cooling equipment (4), and the fan blows the air into the serpentine ventilation duct. When the cold air outside the cover passes over the surface of the radar, the fan is used to realize the forced circulation of the airflow on the surface of the air-cooled equipment, accelerate the convection and heat dissipation, and reduce the local heat accumulation caused by the rear of the radar being on the leeward side of the ventilation.
当只有一个送风口(1)时，送风机(3)的送风量为25000m3/h，送风口(1)直径为0.72m。When there is only one air supply port (1), the air supply volume of the air supply fan (3) is 25000m 3 /h, and the diameter of the air supply port (1) is 0.72m.
具体实施方式二：结合图1说明本实施方式，本实施方式是对实施方式一所述的一种具有通风降温功能的雷达天线罩的进一步限定，本实施方式中，送风口(1)的数量为两个，两个送风口(1)对称偏离雷达天线阵面的正面，两个送风口(1)中心点连线的中心点、雷达天线罩中心、以及出风口(2)的中心共线。Specific embodiment two: This embodiment is described in conjunction with Fig. 1. This embodiment is a further limitation of the radome with ventilation and cooling functions described in Embodiment one. In this embodiment, the number of air supply ports (1) There are two, the two air supply ports (1) deviate symmetrically from the front of the radar antenna front, the center point of the line connecting the center points of the two air supply ports (1), the center of the radome, and the center of the air outlet (2) are collinear .
如图1所示，两个送风口(1)均为圆形，出风口(2)为方形。两个送风口(1)以45°角对称偏离雷达发热体的正面，形成一定的送风倾角。As shown in Figure 1, the two air supply ports (1) are both circular, and the air outlet (2) is square. The two air supply ports (1) deviate symmetrically from the front of the radar heating element at an angle of 45°, forming a certain air supply inclination angle.
根据雷达天线罩的尺寸、雷达散热量来确定风机的通风风量。两个送风口对应两台送风机，可根据室外温度情况实现风机启停控制。当室外温度相对较低时，采用单风机模式，另一台备用；当室外温度相对较高时，则采用双风机模式，两台送风机同时开启。The ventilation air volume of the fan is determined according to the size of the radome and the heat dissipation of the radar. The two air supply outlets correspond to the two supply fans, which can realize the start and stop control of the fans according to the outdoor temperature. When the outdoor temperature is relatively low, the single fan mode is used, and the other is used as a backup; when the outdoor temperature is relatively high, the dual fan mode is used, and the two blowers are turned on at the same time.
具体实施方式三：结合图2至图4说明本实施方式，本实施方式是对实施方式二所述的一种具有通风降温功能的雷达天线罩的进一步限定，本实施方式中，每个送风机(3)的送风量为25000m3/h，送风口(1)直径为0.72m，风速最大为4.3m/s。Specific embodiment three: This embodiment is described in conjunction with Fig. 2 to Fig. 4. This embodiment is a further limitation of the radome with ventilation and cooling functions described in Embodiment 2. In this embodiment, each air blower ( 3) The air supply volume is 25000m 3 /h, the diameter of the air supply port (1) is 0.72m, and the maximum wind speed is 4.3m/s.
本实施方式中，两个送风机(3)的总送风量为2*25000m3/h，两个送风口(1)以45°对称偏离发热体正面，出风口(2)为矩形百叶出风口，尺寸为4m*0.8m。In this embodiment, the total air supply volume of the two blowers (3) is 2*25000m 3 /h, the two air supply outlets (1) are symmetrically deviated from the front of the heating element at 45°, and the air outlet (2) is a rectangular louver air outlet , the size is 4m*0.8m.
图2至图4为模拟的雷达天线罩内的风速矢量场、风速标量场、以及温度场，从模拟结果可以看出，雷达天线罩内空气湍动性较好，通风的整体散热和阵面散热的协同作用明显，送风完全覆盖发热体，可保持雷达天线罩内的温度满足雷达正常工作的要求。Figures 2 to 4 show the simulated wind speed vector field, wind speed scalar field, and temperature field in the radome. From the simulation results, it can be seen that the air turbulence in the radome is better, and the overall heat dissipation and front surface of the ventilation are better. The synergistic effect of heat dissipation is obvious, the air supply completely covers the heating element, and the temperature in the radome can be kept to meet the requirements of the normal operation of the radar.
本发明所述的一种具有通风降温功能的雷达天线罩的具体结构不局限于上述各实施方式所记载的具体技术方案，还可以是上述各个实施方式所记载的技术特征的合理组合。The specific structure of the radome with ventilation and cooling functions in the present invention is not limited to the specific technical solutions described in the above embodiments, but may also be a reasonable combination of the technical features described in the above embodiments.
