Embodiment 1

[0025] Such as figure 1 As shown, a kind of evaporative blower that is used for passenger car, comprises fan body 1 and deflector 4, and the air outlet of described fan body 1 is provided with deflector 4, and the quantity of described deflector is many pieces, many The air deflectors are evenly spaced between each other, and the air deflectors are circular arc structures, and arc-shaped air ducts are formed between adjacent air deflectors. Thereby guiding the wind flow and reducing noise.

[0026] By setting the air deflector at the air outlet of the evaporating fan, the air flow out will run according to the formed air duct, so that the air flow will run more orderly. When the air deflector 4 is designed in a circular arc shape, it is more conducive to supplying air to the inside of the car. Reduce the flow resistance of the air outlet, and at the same time, the air flows in a streamlined manner in the arc-shaped channel, reducing the turbulence of the air flow field, furth...

Embodiment 2

[0028] Such as figure 1 As shown, a kind of evaporative blower that is used for passenger car, comprises fan body 1 and deflector 4, and the air outlet of described fan body 1 is provided with deflector 4, and the quantity of described deflector is many pieces, many The air deflectors are evenly spaced between each other, and the air deflectors are circular arc structures, and arc-shaped air ducts are formed between adjacent air deflectors. Thereby guiding the wind flow and reducing noise.

[0029] On the basis of Embodiment 1, in order to realize the fixing of the air deflector, one end of the multiple air deflectors is fixed on the support plate 5, and the fan body is installed on the chassis 3 of the evaporation chamber, and on the chassis 3 An air outlet is provided at the corresponding position, and the support plate 5 and the chassis 3 are connected by bolts 2.

Embodiment 3

[0031] Such as figure 1 As shown, a kind of evaporative blower that is used for passenger car, comprises fan body 1 and deflector 4, and the air outlet of described fan body 1 is provided with deflector 4, and the quantity of described deflector is many pieces, many The air deflectors are evenly spaced between each other, and the air deflectors are circular arc structures, and arc-shaped air ducts are formed between adjacent air deflectors. Thereby guiding the wind flow and reducing noise.

[0032] In order to realize the fixation of the air deflector, one end of the plurality of air deflectors is fixed on the support plate 5, the fan body is installed on the chassis 3 of the evaporation chamber, and an air outlet is provided at the corresponding position of the chassis 3, The support plate 5 is connected with the chassis 3 through bolts 2 .

[0033] On the basis of the second embodiment, the arc length of the wind deflector increases gradually, and the length difference bet...

Abstract

The invention discloses an evaporation fan for a passenger car and a passenger car air conditioning system. The evaporation fan for the passenger car solves the problem of high air outlet noise of theevaporation fan and reduces the noise reduction cost. The passenger car air-conditioning system applying the fan reduces the noise inside the passenger car and improves the comfort level. The evaporation fan comprises a fan body and flow guide plates, wherein the flow guide plates are arranged at an air outlet of the fan body, the number of the air guide plates is multiple, and the multiple air guide plates are evenly arranged at intervals. When the air guide plates are designed to be arc-shaped, air supply to the inner side of the vehicle is facilitated, and the air outlet flow resistance isreduced. Meanwhile, air flows in an arc-shaped channel in a streamline mode, the turbulence degree of an air outlet flow field is reduced, air outlet noise is further lowered, air noise caused by blowing away of the air flow is lowered, the noise is reduced, the utilization rate of the air flow is increased, and the cooling efficiency is improved; and the air guide plates can be recycled for a long time and is convenient to clean, so that the use cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of fan noise reduction, in particular to an evaporating fan for passenger cars and a passenger car air-conditioning system. Background technique [0002] Modern new energy technology is in a stage of rapid development, among which new energy buses are the most representative product in the process of modern city development. As an important part of new energy buses, the air conditioning technology for buses is not only a test of the cruising range of new energy buses, but also puts forward stricter requirements for passenger comfort. [0003] The air conditioner noise problem is the most prominent among the comfort requirements, and the noise source is mainly concentrated on the evaporator fan installed in the car. Theoretically, the noise of the fan is mainly related to factors such as the type of fan blade, fan speed and air volume, so the selection of the air conditioner fan should focus on the design no...
