The main composition of the DC brushless high static pressure centrifugal fan comprises: a body 10, at least An upper end plate 11 , a lower end plate 丄 2 and a peripheral wall 13 connecting the upper and lower end plates are formed. The main body 1 〇 is disposed near the upper end plate and is provided with a partition 20 , which directly encloses the body 1 . Inside the shape, a first space 14 and a second space 15 are blocked, and the partition 20 is a slanted panel or an arc panel which is gradually inclined downward from the inner wall surface of the peripheral wall of the body 1 , and the inclined surface or The arc-shaped partition plate 20 forms a venting opening 2 for connecting the first and second spaces, and the partitioning plate 20 forms a cover in the second space from the periphery of the venting opening 21 a body 22, a plenum 23 is formed in the hood 22, so that the first space 14, the vent 21, the plenum 23 and the second space 15 are connected in series to a flow path for gas flow; The body 10 corresponds to the periphery of the peripheral wall 13 of the first space 14, and the spacer ring is provided with a plurality of penetrating peripheral walls 13 The mouth 16 is provided for the outside air to enter the body flow path, and the lower end plate 12 of the body 1 is preferably in the form of a slant which is gradually inclined downward from the inner wall surface of the peripheral wall 13 of the body 10 as shown. The panel or the panel structure, the inclined or curved lower end plate 12 extends in the center of a set of segments 12 2 'the surface of the sleeve portion 12 2 penetrates through one of the second spaces to the upper air outlet 12 4 of 201139859, The aforementioned socket portion 12 2 is used for socketing of a pipe fitting (such as a vacuum cleaner, a hand dryer or a spa machine), and then outputted to the destination via the socketed pipe by the wind pressure output from the air outlet 1 24 (such as suction, air drying hand or air bubble) use; a circuit controller 30, is directly placed in the partition 20 vent 21, preferably as shown, is first placed in a shell In the body 40, a plurality of fins 41 for heat dissipation are formed on the outside of the casing 40, and the casing 40 is disposed at the partition 2 #〇 vent 21, and the circuit controller 30 is inside. a driving power crystal for driving a high static pressure centrifugal fan to be described later, and controlling the high static pressure centrifugal a control circuit for fan actuation; and a high static pressure centrifugal fan are disposed in the plenum chamber 23 and electrically coupled to the circuit controller 30. The still static centrifugal fan includes: a brushless motor 5 1 'The surface of the DC brushless motor 51 is formed with a heat dissipating fin 512, and the inside has a mandrel 5 2 which is driven out of the driving end; the front cover 53 is combined and closed. The DC brushless motor 51 is open. The front end of the front cover 53 has a through hole for the mandrel 52 to pass through; a blade 54 is disposed on the outer side of the front cover and is rotated by the mandrel 52, and the outer side of the blade 5 4 And an additional cover for preventing accidental contact can be added as the case may be. The center of the outer cover 5 5 defines an air flow guiding hole 5 5 2 communicating with the venting opening, and the bottom end of the front cover 53 3 can be extended with an inner extending limit. The flow baffle 56 is used to facilitate the gas entering the air guiding hole to be sucked by the strong force of the fan blade, and the limiting baffle 56 is used to concentrate the gas into the heat dissipating fin 5 i 2 of the surface of the DC brushless motor housing. To accelerate the heat exchange speed of the DC brushless motor. 201139859 The "DC brushless high static pressure centrifugal fan" composed of the above structure is operated by the air inlet i6 opened at the upper end wall of the upper end of the body 1 to allow the outside air (referring to cold air) to enter the first space 14 Then, through the body, a beveled (curved) shaped partition 20 and a surrounding cover are designed to allow a gas to pass through the narrow vent 21 when the first space worker 4 passes through the venting opening. A high-static centrifugal fan is added to the fan. The fan is driven by a DC brushless motor that can instantaneously generate high-speed, high-output power. The fan shaft drives the fan blade to rotate at a high speed, and the gas entering and entering the air inlet is quickly sucked in. The reduced diameter venting port allows the cold air to directly exchange heat with the circuit controller 30 on the partition, and the gas is again sucked by the air guiding hole of the outer cover, and then concentrated by the current limiting baffle through the DC brushless motor. The heat-dissipating fins on the surface of the casing are subjected to a second heat exchange, and the hot gas after the heat exchange is discharged through the second space 15 and the air outlet 124 for use as a preset purpose. The DC brushless high static pressure centrifugal fan of the present invention, through the above novel structural design and heat exchange principle, is expected to achieve the following effects: • First: a DC brushless motor driven by a high static pressure centrifugal fan, and a circuit controller for control, The circuit controllers are independently set up and need to maintain the low temperature working temperature, and are placed in the ventilating port position of the inclined surface (or curved surface) after the fin housing, and the cold air entering the air inlet Direct contact with the housing for heat exchange purposes, plus the high-speed centrifugal fan with high-speed rotation of the vortex suction under the vent, can enhance the direct contact speed between the cold air and the housing, so that the thermal energy generated by the circuit controller It has to maintain the normal working temperature by rapid heat dissipation to reduce the probability of high temperature damage. 201139859 Secondly, the addition of the partition and the cover extending inward in the body facilitates the gas entering the first space to have gas pressure and concentration effects, and the high static dust centrifugal fan added in the collecting chamber assists the suction (sending) wind. The heat-dissipating fins that can concentrate the gas into the surface of the brushless DC motor form a second heat exchange function to extend the life of the straight brushless motor. Thirdly, when the DC brushless high static pressure centrifugal fan of the present invention is used in combination with the hand dryer as shown in the third figure, the circuit control Φ device and the high static pressure centrifugation at the vent of the partition plate can be effectively utilized. The hot gas formed by the double heat exchange of the fan is sprayed by the air outlet and then sprayed at a high speed to accelerate the drying effect of the moisture on the user's hand; even when combined with the spa machine, the high static pressure centrifugal fan rotates at a high speed. The wind is collected and pressurized by the air outlet which is greatly reduced by the area. The high-pressure jet effect can be produced, and the massage pressure generated by the spa machine is stronger. Fourth, the DC brushless high static pressure centrifugal fan of the present invention can be used in conjunction with the vacuum cleaner if the reverse setting mode shown in the fourth figure is used to allow the air outlet 12 4 to be exhausted from above. Strong suction characteristics.
