[0002] Inter-row air conditioners can also be called inter-row spaces. They are air-conditioning equipment that integrates cooling, heating, ventilation, and fresh air processing functions. They are precision refrigeration systems specifically designed for use in high-heat-density racks. They are placed directly between server cabinet rows to dissipate heat directly close to the heat source. They can be divided into some air-cooled, water-cooled, and chilled water condensing forms of inter-row air conditioners. Among them, chilled water-type inter-row air conditioners are widely used in the heat dissipation process inside computer rooms due to their efficient cooling and heat dissipation effects. During the use of chilled water-type inter-row air conditioners for cooling and heat dissipation, the adjacent fan components inside the air conditioner are installed close to each other. Therefore, the airflows generated during the operation of the fan are easily affected by each other and will produce additional imaging. A guide mechanism is needed to guide the airflow of the internal fan components to reduce their mutual influence.
