It can be imagined as a widened windmill that accelerates the airflow from one end to the other.<br \/>When the impeller rotates:<br \/>1. Air enters radially into the impeller across its entire length.<br \/>2. Inside the impeller, the air follows a spiral (vortex) path, driven by centrifugal force.<br \/>3. The guide vane redirects part of this internal vortex, stabilizing and accelerating the flow.<br \/>4. The air is then discharged tangentially and evenly along the length of the outlet.<br \/>5. Unlike axial or centrifugal fans, the air path in a cross flow fan is transverse, forming a nearly laminar sheet of airflow, which is useful in applications requiring uniform ventilation over a broad area.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4f91c8a elementor-widget elementor-widget-spacer\" data-id=\"4f91c8a\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4699fba elementor-widget elementor-widget-heading\" data-id=\"4699fba\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">2.The Structure of a Cross Flow Fan<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e62ef12 elementor-widget elementor-widget-image\" data-id=\"e62ef12\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure1-1024x576.jpg\" class=\"attachment-large size-large wp-image-2820\" alt=\"Crossflow fan structure1\" srcset=\"https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure1-1024x576.jpg 1024w, https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure1-300x169.jpg 300w, https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure1-768x432.jpg 768w, https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure1-1536x864.jpg 1536w, https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure1-600x338.jpg 600w, https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure1.jpg 2000w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ed16e98 elementor-widget elementor-widget-image\" data-id=\"ed16e98\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"576\" height=\"1024\" src=\"https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure2-576x1024.jpg\" class=\"attachment-large size-large wp-image-2821\" alt=\"Crossflow fan structure2\" srcset=\"https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure2-576x1024.jpg 576w, https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure2-169x300.jpg 169w, https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure2-768x1365.jpg 768w, https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure2-864x1536.jpg 864w, https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure2-600x1067.jpg 600w, https:\/\/www.fengtech.com\/wp-content\/uploads\/2025\/07\/Crossflow-fan-structure2.jpg 1125w\" sizes=\"(max-width: 576px) 100vw, 576px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-92285c2 elementor-widget elementor-widget-text-editor\" data-id=\"92285c2\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The cross-flow fan is mainly composed of five parts: impeller, casing, motor, bearing, and air duct. The following are the design methods and functions of each component:<\/p><p><strong>1.Impeller<\/strong><br \/>Shape: The impeller is a key component of a cross-flow fan and is usually designed in the shape of a long cylindrical drum. The impeller is surrounded by many thin forward-curved blades. These blades are usually tilted at a certain angle, usually 30-60 degrees relative to the impeller axis, to optimize the airflow direction.<\/p><p>Material: The material of the impeller is usually aluminum alloy. Aluminum alloy impellers have the advantages of high strength, light weight, high temperature resistance, etc., and can maintain stable operation without deformation.<\/p><p><strong>2.Casing<\/strong><\/p><p>The casing is a fixed arc-shaped housing that partially encloses the impeller. It is usually cylindrical or scroll-shaped and is designed with an air inlet and an air outlet. The casing guides the air entering from the air inlet to the impeller and then guides the air discharged from the impeller to the air outlet. It also helps to adjust the airflow shape to make it more uniform and helps reduce noise.<\/p><p><strong>3.Motor<\/strong><br \/>Installation location: The drive motor is usually installed at the end of the drum, outside the airflow, and connected to the impeller through a shaft. This installation method can avoid the influence of the motor on the airflow and ensure the stability of the airflow.<\/p><p>Select type: Different types of motors can be selected according to application requirements. The motor provides power to drive the impeller to rotate, and its speed and power determine the speed and air volume of the impeller.<\/p><p><strong>4.Bearing<\/strong><br \/>Function: Bearings are used to support the rotation of the impeller shaft, reduce friction between moving parts, and ensure smooth rotation of the impeller. This helps improve fan efficiency, reduce energy consumption, and extend fan life.<\/p><p>Installation location: Bearings are usually installed at both ends of the impeller shaft, in contact with the housing or supporting structure to provide stable support and reduce vibration and noise.<\/p><p><strong>5.Air Duct<\/strong><br \/>Shape and design: Ducts are usually stamped from sheet metal and are designed to connect the fan&#8217;s air inlet and outlet to the external air circulation system. Their shape and size are determined by specific application requirements. Ducts guide airflow in and out of the fan and can regulate air volume and pressure.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c866f96 elementor-widget elementor-widget-spacer\" data-id=\"c866f96\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-41005f1 elementor-widget elementor-widget-heading\" data-id=\"41005f1\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">3.
