Description
Technical field
The present invention relates to the blower fan technology, particularly a kind of electromagnetical blower fan.
Background technique
Electromagnetical blower fan is a kind of electric energy to be directly changed into mechanical energy, the contactless transmission blower fan that does not need auxiliary device to change, its transformation of energy and transmit and directly realized by the electromagnetic field working gas gap.The electromagnetical blower fan technology is not also applied at present fully, and the form of its realization is still comparatively single.A kind of electromagnetical blower fan is disclosed in the patent No. is the Chinese utility model patent of ZL90220166.2, mainly connect and compose by linear electric motor, supporting axle, bearing, flow blower casing, impeller, exhaust outlet, variable-frequency governor, the iron core of linear electric motor is curved to be equated with the disk curvature of impeller 5, flow direction is vertical, the static not transmitting torque of the supporting axle of blower fan, impeller self rotate acting under the electromagnetic push effect.This electromagnetical blower fan relatively simple for structure, be mainly used in industrial and mining enterprise's ventilation, but because this electromagnetical blower fan is to rely on the iron core generation electromagnetic induction of impeller and linear electric motor that impeller is driven, its impeller and motor are positioned at the same space, do not separate, so this electromagnetical blower fan can not be applied to need the conveying of closed gas (to ignite gas because of motor may produce spark to flammable explosive gas or other, if or toxic gas leaks and may pollute environment, the person is damaged), thereby can not be applicable to the occasion that gas delivery is had relatively high expectations, using has tangible restriction; On the other hand, in the rotary component operation process, the a large amount of heat of inevitable generation, possible Yin Wendu is too high and make the decreased performance of machine, the transmission of torque amount reduces, rotary component can not use for a long time because of temperature effect, but existing electromagnetical blower fan does not generally all take special measure that the inner heat that produces of rotary component is brought out, some is by changing the rotary component material, increase the type of cooling of forcing cold wind or adding cooling jacket, but these methods are more complicated all generally, and cost is higher, and effect is also not ideal.
Summary of the invention
The shortcoming that the objective of the invention is to overcome prior art provides a kind of rational in infrastructure with not enough, and good heat dissipation effect is safe and reliable to operation, can be applicable to the electromagnetical blower fan that special gas is carried preferably.
Purpose of the present invention is achieved through the following technical solutions: a kind of electromagnetical blower fan, comprise motor, impeller, flow blower casing, it is characterized in that: also comprise outer magnet rotor, interior magnet rotor, separation sleeve, heat pipe axle, described motor is connected with outer magnet rotor, interior magnet rotor is arranged in the separation sleeve, separation sleeve one end of magnet rotor stretches in the outer magnet rotor in being provided with, the separation sleeve the other end is connected with flow blower casing, magnet rotor and heat pipe axle socket-connect in described, described impeller is positioned at flow blower casing, impeller is socketed on the heat pipe axle simultaneously, is connected with interior magnet rotor is coaxial; Described flow blower casing is provided with suction port and air outlet.
Be provided with closed cavity in the described heat pipe axle, described closed cavity comprises endotherm section, the section of transporting and the condensating section that is communicated with successively, charges into certain amount of fluid working medium in closed cavity.
Described liquid working substance can be water, ethanol, mercury etc.
Can earlier closed cavity be pumped into little negative pressure before in closed cavity, charging into certain amount of fluid working medium.
The amount of charging into of described liquid working substance is to be determined by the density of liquid working substance and the composite factors such as density of saturated vapour under the volume of the volume of liquid phase part in the closed cavity, gas phase part, the operating temperature; Generally speaking, its addition can be (13～15) %V, and wherein V is the volume of closed cavity.
