Description

Technical Field

[0001] The utility model relates to the technical field of cabinet fans, in particular to a cabinet fan box. Background Art

[0002] A cabinet fan is a fan product that integrates the motor and fan directly into a casing. It has the characteristics of compact structure, easy installation, and low noise, and is widely used in ventilation, air conditioning, air exchange and other occasions; there are many types of cabinet fans, the most common of which are centrifugal fans, axial flow fans, mixed flow fans, etc. Depending on the application, cabinet fans can also be divided into full static pressure, full dynamic pressure and mixed flow types; among them, centrifugal fans are one of the most commonly used types of cabinet fans. Centrifugal fans can provide sufficient wind pressure and air volume, and can adapt to a variety of different air flow streamline requirements. They have good versatility, so they are widely used in the field of cabinet fans. Axial flow fans are suitable for occasions that require large air volume and low pressure, while mixed flow fans concentrate the advantages of axial flow and centrifugal fans, which can maintain a large air volume and ensure a high wind pressure.

[0003] At present, the existing cabinet fans usually include a motor, an impeller, a chassis and a control system. The working principle is: the control system drives the motor to work, and then the motor drives the impeller to rotate at high speed, thereby generating wind power.

[0004] In the above scheme, the existing chassis is usually spliced ​​together by multiple box panels, and the box panels are usually filled with sound-absorbing cotton to reduce the noise generated when the cabinet fan is working. However, the sound-absorbing cotton is relatively soft. In order to ensure the strength of the box panels while ensuring noise reduction, it is usually necessary to increase the thickness of the box panels, which makes the chassis heavier and increases the production cost. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a cabinet-type fan case, in which the main case plate and the side case plate are filled with polyurethane foam, thereby enhancing the strength of the main case plate and the side case plate, thereby solving the problem in the prior art of requiring the main case plate and the side case plate to be thickened to improve the strength of the main case plate and the side case plate, thereby eliminating the need to increase the thickness of the main case plate and the side case plate and reducing production costs.
