In existing technology, the heater unit of automobile often normally uses because work noise affects it greatly in the course of the work, also affects the mood of chaufeur, makes its agitation, and then may cause some evitable safety misadventures.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of automotive fan heater that reduces noise, to solve the above-mentioned multinomial defect causing in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of automotive fan heater, comprise the casing that is built-in with blower fan assembly and heat radiator assembly, heat radiator assembly is fixed on casing below, by radiator, coolant inlet pipe and coolant outlet pipe form, coolant inlet pipe and coolant outlet pipe are connected into cycle of engine water system, blower fan assembly is fixed on casing top, by impeller, motor and base form, the impeller base that was connected with motor is fixed on casing, casing one side is provided with ventilation inlet, casing top is provided with the discharge pipe communicating with casing, described impeller is that double sided impeller is set in parallel on base.
Preferably, described double sided impeller is all forward direction impeller.
Preferably, the number of sheets of described double sided impeller is 10-15 sheet.
Preferably, described motor is magneto-electric machine.
Preferably, between described base and casing, be provided with rubber mount, the thickness of rubber mount is 3-7mm.
Preferably, described casing outer side covers has soft foam-rubber cushion, and the thickness of soft foam-rubber cushion is 3-7mm.
Preferably, described coolant inlet pipe and coolant outlet pipe are India rubber tube.
Adopt the beneficial effect of above technical scheme to be: the impeller of the heater unit of the utility model structure is double sided impeller, in the situation that reducing wheel speed, serviceability is compared with single impeller, also had lifting to a certain degree, and reduce wheel speed, can effectively must reduce noise; Double sided impeller is all forward direction impeller, and impeller has two kinds, forward direction impeller and backward impeller, in the situation that heater unit is carried the hot air of same traffic, the noise of the generation of forward direction impeller is less than backward impeller; The number of sheets of double sided impeller is 10-15 sheet, and the number of sheets of impeller is more, and blade is better in the flow property of Ye Daonei (i.e. two interlobate gas flows) gas more by force to the constrained force of gas effect, and the noise of generation is less; Motor is magneto-electric machine, and magneto-electric machine, except configuration aspects has many advantages, and is also having certain effect reducing aspect noise of motor, and that irksome brush noise, rotor shifting noise also reduce to some extent; Between base and casing, be provided with rubber mount, carry out the isolation of soruce of vibration, eliminate resonance effect; Casing outer side covers has soft foam-rubber cushion, reduces the mechanical noise that body structure vibration institute width is penetrated.
