This PCB75 will be described with particular reference to Fig. 3,4b, 11a, 11b, 12a, 12b and 12c now.This PCB75 be annular or ring-type, and around pipeline 310, extend between pipeline 310 and the outer wall 360.In this embodiment, this PCB75 has two plates, and the first plate 75a extends a complete cycle around pipeline 310, and the contiguous first plate 75a of this second plate 75b and in the downstream of the first plate 75a.This second plate 75b only partly extends around pipeline 310 around fluid flow path 300.

This PCB75 contains some different parts, and each parts extend the plate difference amount of installing away from it.With particular reference to Fig. 3,4b, 12a, 12b and 12c, large parts 77 (such as capacitor) are positioned on the first plate 75a, radially away from the second plate 75b.This has some advantages, such as PCB75 is fabricated to compact as much as possible, because less parts or extension are double-layer overlappings away from those parts that installed plate is minimum, and larger parts or those extensions are that individual layer is installed away from installed plate those parts farthest.

This another advantage of arranging on PCB75 is when major fluid flow path moves into body 30 from handle 20, the drifting management of fluid in major fluid flow path 400.With reference to figure 3,4b, 12b and 12c, handle 20 is generic tubular, and major fluid flow path 400 is substantial circular when it enters the joint portion 90 between handle 20 and body 30.At this some place, major fluid flow path 400 changes 90 °, direction, and changes into around the annular fluid of pipeline 310 between pipeline 310 and the outer wall 360 of body 30 from circular flow.These change the flowing velocity affected in major fluid flow path 400.

If we consider that body 30 is about center line A-A (extension of its length along body 30) symmetrical, pipeline 310 and outer wall 360 concentric, the heater 80 be positioned between pipeline 310 and outer wall 360 is also like this.When the fluid in major fluid flow path 400 arrives the joint portion 90 between body 30 and handle 20, fluid must change direction and shape.This in body 30, limit, joint portion 90 produces high-speed flow area, and the region be radially spaced from joint portion 90 in body 30 produces the flow region compared with low velocity.If we think that body 30 has the first half 380 and Lower Half 390, wherein the first half 380 radially spaced far from handle 20, and Lower Half 390 comprises the joint portion 90 between body 30 and handle 20, then Lower Half 390 has the flowing under the speed relatively higher than the first half 380.

This PCB75 is oriented as and makes larger parts 77 be arranged in the first half 380, in relatively low speed flowing (radial away from relative high-speed region), they is lowered on the impact of the fluid velocity in hair dryer.Double-deck 75a, the 75b of PCB75 are arranged in Lower Half 390, because this part of PCB75 less extends into major fluid flow path 400.

Additionally, flow plate 700 is provided to bending or guides the fluid in major fluid flow path 400 to cross and around PCB75, to minimize further due to the position of PCB and any pressure loss of causing because the direction of major fluid flow path 400 when it enters body 30 changes.This flow plate 700 is annular, has bending section 710 (Fig. 3,4b, 11a, 11b, 12a, 12b and 12c), and this section is that the orientation of major fluid flow path 400 or direction provide steady change.By providing curved surface 710, fluid is guided by around turning, reduces and changes by direction vertical the noise that produces and reduce the speed loss of any pressure loss or fluid.Whole flow plate 700 can be bending, but just can be found out by only making the part in the Lower Half 390 being positioned at body 30 of flow plate 700 have curved surface 710.

The contiguous PCB75 of this flow plate 700, and advantageously, flow plate 700 is connected to PCB75 by bridger 720.This flow plate 700 is made up of conductive material, be preferably metal material, such as aluminium or its alloy, therefore, this bridger 720 provides the radiator for PCB75, this radiator from the parts draw heat of PCB, and guides heat to enter the fluid (when it is through flow plate 700) flowing through fluid flow path.

Additionally, this flow plate 700 serves as the thermodynamic barrier for PCB75, and any temperature-sensitive components is mounted thereon.Heater 80 is arranged on the downstream of joint portion 90 in body 30, between body 30 and handle 20 and PCB75, and when fluid flow through major fluid flow path 400 be namely opened when hair dryer time, the heat that major part (if not all) is produced by heater 80 will be brought to primary fluid outlet 440.But when hair dryer is closed or open for subsequent use, heater will send remaining heat, this heat will be by radiation upstream and downstream, and therefore flow plate also serves as the thermodynamic barrier for PCB75 ideally.

The Fluid Sealing PCB75 of this flow plate 700 not in fluid relative flow path, but it enables fluid flow around PCB75, (Figure 12 a) to be passed in the opening 730 (illustrating especially in fig. 4b) between flow plate 700 and body 30 or the groove 740 in flow plate.

Flow plate 700 has another function.When one or more parts (capacitor on such as PCB75) fault, flow plate 700 serves as deflecting plates, it returns turning to from any fragment of unit failure and/or electrolyte towards sidewall 350, and prevent fragment and/or electrolyte from entering major fluid flow path 400, in major fluid flow path, it will meet with heater 80 and primary fluid outlet 440.
