Claims

[Claims for Utility Model Registration] At both ends of a cylindrical duct in which a motor and a fan are mounted, a substantially square shape symmetrical to the axis of the duct and orthogonal to the axis, with a predetermined thickness t _{0 and} length L across sides. A square fan unit with a planar flange is mounted on a structure that requires air cooling, and is made of a relatively soft elastic or elastoplastic material.
The external shape is approximately square with thickness T and opposite side length L + 2t ₃ , with a three-layer communication opening in the center, thickness T is T = t ₀ + t ₁ + t ₂ , and there is a wall thickness t ₁ on the top and bottom surfaces. A gap is formed in the center where the thickness t ₂ is left, and a gap t ₃ is left around the periphery to engage and accommodate the flange having the thickness t ₀ and _the length L across sides. An opening corresponding to the diameter of the duct is formed in the upper surface, and an engaging part that accommodates and engages the four corners of the flange is left on the upper surface with a wall thickness of _t1 , and the side part has an excess wall thickness of _t3. Prepare an intermediate member for mounting formed in the opening while leaving the above, ○B For the structural part, form an opening corresponding to the diameter of the duct in the center, and around the opening axially symmetrical with the opening center. At orthogonal positions, there is a facing dimension L + 2t ₃ for engaging with the opposite side of the intermediate member, a rising dimension T, and an approximately facing dimension L at the upper part.
1. A mounting structure for a rectangular fan unit, characterized in that a pair of holding parts are formed, each having a claw that looks like this, and the fan is attached to the holding parts using the intermediate member as an intermediary.
