Abstract
A noise abatement device for automobile-used warm air blowers is characterized in that a noise member is arranged at the intake of the warm air blower and protrudes in the air intake direction, and the upper part of the bulge is smaller while the lower part is larger; the bulge is the joint portion of the two surfaces; the joint portion of the two surfaces has an arc in shape; the surface of the noise abatement device facing the intake is a curved surface; the surface of the noise abatement device facing the inside wall of the intake of the warm air blower is a curved surface. The device has the advantages that the noise given out by the warm air blower is reduced effectively and the automobile is more comfortable.
Description
Technical field
The utility model relates to a kind of automotive fan heater noise-decreasing device that automobile is carried out noise abatement with the noise of heater unit.
Background technology
It is the overriding noise source in vehicle drive cabin that automobile is made an uproar with the wind of heater unit, and particularly when wind speed is higher, wind makes an uproar almost that the exponentially level increases, and brings very big challenge for the traveling comfort of automobile.
Summary of the invention
The purpose of this utility model just provides and a kind ofly according to hydromechanical principle corresponding structure is set, and reduces the automotive fan heater noise-decreasing device of noise.
Solution of the present utility model is such: be provided with the noise abatement member that protrudes to the air intake direction in the heater unit ventilation inlet, noise abatement member boss is up-small and down-big, the noise abatement member that utilization is provided with in the air intake direction is provided with the noise abatement member in the place of heater unit ventilation inlet formation eddy current and carries out noise abatement.
The utility model has the advantages that by the noise abatement member is set, reduced the noise of heater unit effectively, improved the traveling comfort of automobile.
