技术领域technical field
本实用新型涉及一种户外密闭式风冷机柜。The utility model relates to an outdoor sealed air-cooled cabinet.
背景技术Background technique
工作于沙漠地区和沿海地区恶劣环境下的户外机柜、例如电气柜，特种功能柜，控制柜等，一般长期处于无人值守状态，因此为了防止恶劣的环境(风沙侵蚀或是盐雾腐蚀)损坏机柜内部电子元件，需要将机柜做成密封结构，但密封结构不利于内部电子元件的散热，需要优异可靠的散热方式，为内部电子发热元件提供良好的散热路径，来保证内部电子元件工作在安全的温度范围内。Outdoor cabinets working in harsh environments in desert areas and coastal areas, such as electrical cabinets, special function cabinets, control cabinets, etc., are generally unattended for a long time, so in order to prevent damage to the harsh environment (wind and sand erosion or salt spray corrosion) The internal electronic components of the cabinet need to be made into a sealed structure, but the sealed structure is not conducive to the heat dissipation of the internal electronic components, and an excellent and reliable heat dissipation method is required to provide a good heat dissipation path for the internal electronic heating components to ensure that the internal electronic components work in safety. within the temperature range.
目前为保证散热，目前户外机柜采用的方案有开放式方案，即机柜内部元件与环境接触，依靠风扇将环境风吹过内部元件散热器，将热量带入环境，此种机柜体积小，换热效率高，功耗小，缺点是无法有效屏蔽恶劣的环境影响，整体故障率较高；另一种方案是将机柜做成密闭式，然后外挂空调的方式，此种方案散热效果好，但是功耗较高，且冷量受体积限制，无法做到较强冷却能力，而且空调曝露在恶劣环境中，虽然柜体内部元件故障率下降，但空调的故障率上升，同样不利于整体系统的稳定运行；还有一种密闭柜方案是在设备柜旁边设置一个冷却柜，在设备柜内部设置换热器，工作介质为水或防冻液，将机柜内部热量带入到冷却柜，通过风冷换热将热量排入环境，此种方案换热稳定，故障率低，但是整体结构松散，占地空间大，由于采用了工质循环泵，功耗也较大。At present, in order to ensure heat dissipation, the current scheme adopted by the outdoor cabinet has an open scheme, that is, the internal components of the cabinet are in contact with the environment, relying on the fan to blow the ambient wind through the internal component radiator, and bring the heat into the environment. This kind of cabinet is small in size and easy to exchange heat. High efficiency and low power consumption. The disadvantage is that it cannot effectively shield the impact of harsh environments, and the overall failure rate is high. The power consumption is high, and the cooling capacity is limited by the volume, so it cannot achieve a strong cooling capacity, and the air conditioner is exposed to harsh environments. Although the failure rate of the internal components of the cabinet decreases, the failure rate of the air conditioner increases, which is also not conducive to the stability of the overall system. There is also a closed cabinet solution that is to set up a cooling cabinet next to the equipment cabinet, and set a heat exchanger inside the equipment cabinet. The working medium is water or antifreeze, and the heat inside the cabinet is brought into the cooling cabinet, and the heat is exchanged through air cooling. The heat is discharged into the environment. This kind of scheme has stable heat exchange and low failure rate, but the overall structure is loose and occupies a large space. Due to the use of a working fluid circulation pump, the power consumption is also large.

The gas enters the second heat exchange air channel through the drainage air channel, continues the heat exchange, and returns to the cabinet under the action of the induced draft fan group; while exchanging heat, the heat exchange blower fan group and the heat exchange induced draft fan group are Cold air (that is, ambient air) is pumped into the heat exchange air duct; this process is cycled multiple times to cool the gas in the cabinet.
实施例2Example 2
本实施例与实施例1的区别在于，如图5所示，扁管换热板23中设有多个肋板24，将扁管换热板内部分成若干腔室，气流从腔室中流过，进行换热。The difference between this embodiment and Embodiment 1 is that, as shown in FIG. 5 , a plurality of ribs 24 are provided in the flat tube heat exchange plate 23 to divide the interior of the flat tube heat exchange plate into several chambers, and the air flows through the chambers. , for heat exchange.
实施例3Example 3
本实施例与实施例1的区别在于，扁管换热板23中设有若干沟槽，机柜中的气流从沟槽中流过，与扁管换热板进行接触，进行充分换热。The difference between this embodiment and Embodiment 1 is that the flat tube heat exchange plate 23 is provided with several grooves, and the airflow in the cabinet flows through the grooves and contacts with the flat tube heat exchange plate for sufficient heat exchange.
