Technical Problem
[0005]有鉴于此，本实用新型旨在提出一种广播电视工程发射机冷却装置，以解决现有风冷手段在对工程发射机冷却时积灰严重导致冷却失效的问题
Benefits of technology
本装置将传统机壳的进气口和出气口进行集成，气体经风机带动从进气口进入会被过滤部进行过滤，而多个过滤部形成的旋流方向不同，使得在下一过滤部表面形成剪切作用，从而防止滤孔发生结构性堵塞，从而使用保持有效过滤的状态，延长有效冷却时间，气体作用于散热部对设备进行冷却后在机壳内循环后流动到出气口处，在喷嘴和正压作用下向下流动形成风幕，作用于进气口，一方面，进气口和出气口集成布置配合机壳内部空间形成循环流场，增大气体循环量，同时风幕能够减少灰尘的进入量，而增大的循环量以及风力动能又会配合过滤部形成强剪切作用，进一步提升防堵塞过滤的效果。本装置将进气口和出气口进行耦合集成设置后配合液冷循环，从而使机壳内循环的气体整体温度进一步下降，而此种集成方式能够避免使用大体积、大循环流量的液冷模块，有助于降低运行成本，同时能够避免出现纯风冷带来的物理冷却极限。本装置通过在集成部壳体的进气口对应部分的外壁套设背压管，使得在进气口吹出的气体在背压管内形成背压区，背压区上方的出气口周围气体会受到背压区引力，从而使逃逸到机壳内的粉尘颗粒，尤其是大块颗粒与将要排出的气体进行分离到背压区气体转向区的收集部内，这样可以保证收集部内的颗粒进行有效收集不会发生二次掺入气流，定期清理收集部即可。
