FIG. 1 shows afan assembly 100 according to an embodiment of the invention. Thefan assembly 100 includes animpeller 102, aninlet 106, and anoutlet 108. Amounting frame 104 is coupled to theassembly 100 to position the assembly within its associated ductwork or other location for movement of air, gas, or other fluids. - In the example shown, the
fan assembly 100 is a centrifugal fan, although the invention is not so limited. Examples of the invention may also be used with axial impellers, and/or mixed flow impellers. Examples of the present invention may be used with any fan assembly using a housing with multiple portions where a seam is used to join two or more portions. - The
fan assembly 100 ofFIG. 1 shows afirst housing portion 110 and asecond housing portion 112 that are joined together at aseam 120. In the example shown, thefirst housing portion 110 and thesecond housing portion 112 are formed from a composite material. In one example, the composite material includes fiber glass. Other examples of composite materials include, but are not limited to, carbon fiber composites, resin and aramid composites such as Kevlar, or other fiber reinforced composites. - As noted above, in selected fan applications such as moving corrosive gasses, or applications where weight is a concern, multiple components of the
fan assembly 100 may be formed from a composite material. In one example theimpeller 102 may be formed from a composite material. - In one example composite portions may include multiple layers of composite material, for example multiple laminated composite fabrics, or chopped fiber reinforced layers, combinations of layers, etc. In one example, a metal layer or other non-composite material may be included within a stack of layers, with the final layer that will contact the fluid or gas being a non-corrosive layer. In one example one or more layers may include a non-reinforced polymer.

FIG. 2 shows a cross section of portions of afan housing 200, such as thefirst portion 110, and thesecond portion 112 fromFIG. 1 . InFIG. 2 , afirst housing portion 202 and asecond housing portion 204 are shown forming aseam 210. In the example shown, thefirst housing portion 202 and thesecond housing portion 204 include multiple layers. Thehousing portions FIG. 2 include at least onewoven roving layer 206 with an outer choppedgun roving layer 208. In the example shown, there are two woven rovinglayers 206 and both an inside and an outside of thefan housing portions gun roving layer 208.

FIG. 2 shows thefirst housing portion 202 and thesecond housing portion 204 joined together at theseam 210 with an adhesive 214. One example of anacceptable adhesive 214 includes two part methacrylate adhesive. -
FIG. 2 shows at least one reinforcing layer adhered over theseam 210 on an inside 200A of thehousing 200. In the example shown, multiple reinforcing layers are adhered over theseam 210.FIG. 2 shows multiplewoven roving layers 222 and a choppedstrand mat layer 224 adhered over theseam 210 on an inside of thehousing portions woven roving layers 222 are first adhered over theseam 210, with a single choppedstrand mat layer 224. Although this combination of multiple layers is used as an example one of ordinary skill in the art will recognize that various other combinations of one layer or multiple layers adhered over theseam 210 on an inside 200A of thehousing 200 may be effective as well. - In use, the reinforcing layers, such as
layers seam 210 and improve the structural integrity of thehousing 200 as a whole. In this way, multiple housing portions such asfirst housing portion 202 andsecond housing portion 204 can be joined together in an improved seam that is stronger than a seam without reinforcement. - In one example, at least one second reinforcement layer is included to cover the
seam 210 on an outside 200B of thehousing 200. InFIG. 2 , two layers of choppedstrand mat 230 are shown covering theseam 210 on an outside 200B of thehousing 200. Although twolayers 230 are shown, one of ordinary skill in the art, having the benefit of the present disclosure, will recognize that one layer, or more than two layers may also be effective, depending on the design parameters of a specific fan assembly. - In the examples shown, both the first reinforcing layers, such as
layers layers 230 are glass fiber composite layers. As with thehousing portions layers layers layers 230 strengthen theseam 210 and improves the structural integrity of the housing as a whole. -
FIG. 2 further shows amechanical fastener 234 clamping theseam 210 together on the outside of the housing. In the example shown, themechanical fastener 234 not only passes through a portion of thefirst housing portion 202 and thesecond housing portion 204, but also passes through the second reinforcing layer orlayers 230. In one example, themechanical fastener 234 is further reinforced by adding anadhesive 236 within the hole that themechanical fastener 234 passes through. In one example, theadhesive 236 includes two part methacrylate adhesive, similar to theadhesive 214 used between thefirst housing portion 202 and thesecond housing portion 204. - In the example of
FIG. 2 , a portion of thefirst housing portion 202 and thesecond housing portion 204 include extendingportions housing 200 to form an extendingportion 212. In the example shown, the second reinforcing layer orlayers 230 form a channel that covers the extendingportion 212. In one example, the second reinforcing layer orlayers 230 are adhered over theseam 210. In other examples, the second reinforcing layer orlayers 230 are not adhered to thehousing 200, but are instead placed over theseam 210 and held in place using themechanical fastener 234. - In one example the
seam 210 includes one or more wraps of poly strapping 232 that cover the exposedadhesive 214 prior to placement of the reinforcing layer orlayers 230. In the example shown, themechanical fastener 234 includes a bolt and a nut, although any number of mechanical fasteners are within the scope of the invention, including, but not limited to, rivets, screws, barbed fittings, etc. - Although the
example seam 210 and theexample fan assembly 100 show a single seam, the invention is not so limited. In other examples, multiple housing portions may be joined together using configurations described above to form a housing for a fan assembly. -
