Abstract
The utility model discloses a super thin disk fan, which is characterized in that the utility model is provided with a thin casing, a disk type electric machine is arranged in the thin casing, and a fan impeller is directly connected with the disk type electric machine. The utility model has the advantages of thin thickness, light weight, small external dimensions, small size and novel and unique structure.
Description
The utility model relates to general machinery equipment, is a kind of logical, blowing device, specifically, is a kind of blower fan of thin type.
Blower fan is to use machinery very widely.Existing blower fan all has big thickness usually, and therefore bigger restriction is arranged in the use, and as to the lower pipe laying supercharging equipments such as tall building of existing floor the time, the blower fan that existing thickness is bigger will be difficult to use.This mainly is owing to existing blower fan is to adopt common motor to cause.Existing common electric machine is at the embedded son that sets of motor casing, is rotor in the stator.These existing motor have bigger axial dimension, when therefore being loaded on the blower fan, just must cause the thickness of blower fan bigger.In addition, the manufacturing efficiency of existing common electric machine is low, and operation is many, and die cost is big.Speed adjusting performance is poor, because of its revolutional slip little.During the variable voltage control operation, electric current obviously increases, and speed governing is not obvious again, and long-time running is unreliable, even can burn motor.Conventional motors is installed impeller by shaft extension, can not reach the requirement of blower fan thin thickness.
The purpose of this utility model provides a kind of in light weight, boundary dimension is little, volume is little ultrathin disc type blower fan.
Technical solution of the present utility model is: a kind of ultrathin disc type blower fan is characterized in that: a slim casing is arranged, in the slim casing disc type electric machine is housed, draught fan impeller directly is connected with disk type electric motor rotor.
The stator that is fixed in the motor casing of the disc type electric machine described in the utility model is a plate-like, is loaded on the side that disc-like rotor on the main shaft is positioned at stator.The stator of disc type electric machine, the flute profile of rotor distribute radially, embed winding in the stator slot; Rotor is a cage type cast aluminium structure, and forms certain skewed slot.The embedding filler is arranged between the staor winding of disc type electric machine and motor casing.The profile thickness size of slim casing is 120-200mm.Certainly, also can adopt other suitable specific constructive form.
The utility model has the advantages that: in light weight, boundary dimension is little, volume is little, novel structure is unique, applied range.It is supporting to can be used for comfort air conditioning system, and pipe pressurizing ventilates, and it is lower to satisfy the tall building floor, the place that setting height(from bottom) is subject to certain restrictions, and, thickness less to the volume ratio of idle call blower fan will approach and necessarily require occasion.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of a kind of ultrathin disc type blower fan of the present utility model;
Fig. 2 is the side view of Fig. 1.
Fig. 1, Fig. 2 have described an embodiment of the present utility model jointly.In this embodiment, a slim casing 1 is arranged, in the slim casing 1 disc type electric machine 4 is housed, draught fan impeller 5 directly is connected with disc type electric machine 4 rotors.The stator that is fixed in the motor casing of disc type electric machine 4 is a plate-like, is loaded on the side that disc-like rotor on the main shaft is positioned at stator.The stator of disc type electric machine, the flute profile of rotor distribute radially, embed winding in the stator slot; Rotor is a cage type cast aluminium structure, and forms certain skewed slot.The embedding filler is arranged between the staor winding of disc type electric machine 4 and motor casing.The profile thickness size of slim casing 1 is 150mm (or other suitable concrete size numerical value).The slim casing of blower fan etc. can adopt full galvanized sheet material.Also comprise parts such as back shroud 2, three-support 3, footing angle bar 7, connecting plate 8 in the above-mentioned accompanying drawing, 6 is intake grill.The flow of the foregoing description is 1500-3300m
3/ h, pressure are 710-500Pa, and efficient is 68%.
