Description

Technical Field

[0001] This utility model relates to the field of fan housing technology, specifically a cabinet-type fan housing. Background Technology

[0002] A cabinet-type fan is a fan product that integrates the motor and fan directly into a single casing. It features a compact structure, easy installation, and low noise, and is widely used in ventilation, air conditioning, and air exchange applications. There are many types of cabinet-type fans, including centrifugal fans, axial fans, and mixed-flow fans. Depending on the application, cabinet-type fans can also be categorized as all-static pressure, all-dynamic pressure, and mixed-flow types.

[0003] Existing fan enclosures are generally made of multiple panels connected together, with sound-absorbing materials such as sound insulation boards glued inside the panels. This reduces the installation space inside the enclosure and lowers its practicality. To address this, we propose a cabinet-type fan enclosure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cabinet-type fan housing, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cabinet-type fan housing comprising multiple mounting plates, each mounting plate having an internal groove filled with sound-absorbing material. The mounting plate also has four corresponding wedge-shaped grooves, each wedge-shaped rod inserted into one of the grooves. An outer protective plate is fixedly connected between the four wedge-shaped rods. The outer protective plate has a limiting groove, and a first limiting rod and a second limiting rod are slidably connected within each limiting groove. A top rod is fixedly connected to the outer side of the first limiting rod, and a side rod is fixedly connected to the outer side of the second limiting rod.

[0006] Preferably, two of the top rods have a first fixing groove inside, and the other two top rods are fixedly connected to a first fixing block on the outside. The first fixing block is inserted into the first fixing groove and fixed by bolts.

[0007] Preferably, the bottom of the top rod is fixedly connected to two corresponding positioning rods, and the side rod has a positioning groove inside, into which the positioning rod is inserted.

[0008] Preferably, the bottom of the top rod is fixedly connected to four corresponding second fixing rods, and the side rod has two corresponding second fixing slots inside, into which the second fixing rods are inserted.

[0009] Preferably, the mounting plate has two corresponding L-shaped grooves inside, and L-shaped rods are fixedly connected to the outer sides of the side rods and top rods, with the L-shaped rods inserted into the inside of the L-shaped grooves.

[0010] Preferably, the mounting plate has two corresponding insertion slots inside, and the bottom of the outer protective plate is fixedly connected to two corresponding insertion rods, which are inserted into the insertion slots.

[0011] Preferably, the sound-absorbing material can be polyurethane foam, industrial felt, or modified sponge, depending on the requirements.

[0012] This utility model provides a cabinet-type fan housing, which has the following beneficial effects: 1. This cabinet-type fan enclosure closes the outer protective plate and mounting plate by filling the inner groove with sound-absorbing material, inserting the plug-in rod into the plug-in groove, and then engaging the wedge rod into the wedge groove. Next, by inserting the L-shaped rod into the L-shaped groove and engaging the first and second limiting rods into the limiting groove, the outer sides of the mounting plate and outer protective plate are limited, ensuring stability when closed. Finally, by inserting the positioning rod into the positioning groove and the second fixing rod into the second fixing groove, the side rod and top rod can be connected, facilitating disassembly and maintenance and improving the practicality of the cabinet-type fan enclosure.
