Description

A kind of fan assembly and air conditioning unit

Technical field

The utility model relates to a kind of fan assembly, and applies the air conditioning unit of this fan assembly.

Background technology

Aerofoil fan has the feature of low pressure, large discharge, and at present, the upper multi-joint unit of air-out etc. adopt aerofoil fan to carry out set heat exchange mostly. But adopt aerofoil fan air conditioning unit have air conditioning unit interior flow field distribution uneven, the shortcoming that heat exchange efficiency is low, because the position pressure reduction of close aerofoil fan is big, wind speed is fast, position pressure reduction away from aerofoil fan is little, there is certain resistance in the interchanger being simultaneously connected with aerofoil fan, making heat exchanger surface wind speed profile along interchanger height direction rapid decrease, the speed of bottom is close to zero even sometimes.

As shown in Figure 1, interchanger 1 ' has the first end 11 ' that contiguous fan assembly 2 ' is arranged and the 2nd end 12 ' arranged away from fan assembly 2 ', namely first end 11 ' is arranged on the uppermost position in interchanger 1 ' height direction, 2nd end 12 ' is arranged on the bottom position in interchanger 1 ' height direction, when fan assembly 2 ' works, the speed of first end 11 ' is maximum, the speed of the 2nd end 12 ' is minimum, sometimes even it is close to zero, this kind of situation easily causes each exchange capability of heat along separate routes of interchanger 1 ' uneven, cause part heat exchange manifold waist performance, heat interchanging area can not be made full use of, it is difficult to promote heat exchange efficiency and the performance of unit. also to be adjusted each shunt cold medium flux according to this situation during system matches, add many coupling workloads. in addition, the structural limitations of the existing air conditioning unit and fan assembly height dimension ratio of blower fan diameter and interchanger, adds difficulty virtually to air conditioning unit design and improved performance.

Embodiment

In description of the present utility model, it will be appreciated that, it is based on orientation shown in the drawings or position relation that the orientation of the instruction such as term " outside ", " inside ", " highly ", " top ", " lower section " or position are closed, it is only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device referred to or element must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model.

In addition, term " first ", " the 2nd " are only for describing object, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating indicated technology feature. Thus, be limited with " first ", the feature of " the 2nd " can express or implicit comprise one or more these features.

Below in conjunction with accompanying drawing and by embodiment, the technical solution of the utility model is described further.

As shown in Figures 2 and 3, the Fan casing 2 that fan assembly comprises blower fan 1 and is arranged at outside described blower fan 1, described Fan casing 2 sets into air port and air draft mouth, in described blower fan 1 near described in enter air port side guiding device 3 is set, described guiding device 3 comprises flow deflector 31, described flow deflector 31 enters air port described in correspondence pod apertures 32 is set, the side that described flow deflector 31 deviates from described Fan casing 2 arranges multiple guide vane 33, multiple described guide vane 33 is circular layout along the circumference of described pod apertures 32, the part projection of guide vane 33 described in each on described flow deflector 31 drops in described pod apertures 32, described guide vane 33 is non-perpendicular setting with the center axis of described pod apertures 32. the method that the fan assembly of this scheme realizes THE HURRICANE FLOW FIELD mainly drives surrounding flow move and rotate by blower fan 1 operation, form a rotary area entering air port place, due to the characteristic of swirling eddy, the speed of rotation of air-flow increases along radius direction and reduces, thus it is big to form gas velocity inside rotary area, pressure is little, outside gas velocity is little, pressure is big, thus produce pressure gradient, and then peripheral gas flow is collected to center, collect air-flow after guiding device 3, the air flow line entering flow field can be adjusted, strengthen swirling eddy further, thus form a small-sized rotational flow field in air conditioning unit inside, the suction function of its brute force makes air-flow more easily enter air conditioning unit inside to carry out heat exchange, and discharge via blower fan 1 and baffle liner 4 fast, more be conducive to improving heat exchange efficiency and exchange capability of heat, make full use of heat exchanger area. the fan assembly of this structure is used in upper air-out air-conditioners group can improve unit performance. in the present embodiment, be non-perpendicular setting by the center axis of guide vane 33 with pod apertures 32, it is possible to what be conducive to being formed spirrillum enters wind air channel, and then formation THE HURRICANE FLOW FIELD. if be vertical setting by the center axis of guide vane 33 with pod apertures 32, then what be unfavorable for formation spirrillum enters wind air channel.

Concrete, each guide vane 33 is obliquely installed in the same direction, and angle between each guide vane 33 and center axis of pod apertures 32 is equal.

In the present embodiment, guide vane 33 is perpendicular to flow deflector 31. But being not limited to vertical connection between guide vane 33 with flow deflector 31, it is also possible to be set to, the angle between guide vane 33 and flow deflector 31 is less than 90 ��.

As shown in Figure 3, the section structure of guide vane 33 is straight sheet, certainly, the section structure of guide vane 33 is not limited to straight sheet structure, can also plunder in type, shuttle-type or streamlined structure for curved any one, as long as there is certain angle between each guide vane 33 and center axis of pod apertures 32, the air-flow by these guide vanes 33 just can be allowed to have an effect and to form a kind of swirling eddy such as wind spout shape.

Concrete, on Fan casing 2 and be positioned at air draft mouth place and be provided with baffle liner 4. By arranging baffle liner 4 at air draft mouth place, it is possible to the wind sent by blower fan 1 is carried out water conservancy diversion, accelerate the conveying of air-flow. In the present embodiment, baffle liner 4 is one-body molded with Fan casing 2.

Flow deflector 3 and Fan casing 2 removably connect, so that the maintenance service in later stage. Concrete, arranging between Fan casing 2 and guiding device 3 and crossbeam 5 is installed, Fan casing 2 and guiding device 3 removably connect with installation crossbeam 5 respectively. Installing crossbeam 5 comprises in parallel and spaced first crossbeam 51 and second cross beam 52, and first crossbeam 51 lays respectively at pod apertures 32 or enters the relative both sides in air port with second cross beam 52.

In the present embodiment, guide vane 33 is fixedly installed on flow deflector 31, and therefore, the angle between guide vane 33 and flow deflector 31 immobilizes.

In other embodiments of the present utility model, the setting device for regulating the angle size between the center axis of guide vane 33 and pod apertures 32 is set between guide vane 33 and flow deflector 31.

The utility model embodiment also provides a kind of and adopts the air conditioning unit of described fan assembly.

Below know-why of the present utility model is described in conjunction with specific embodiments. These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way. Based on explanation herein, the technician of this area does not need to pay creative work can associate other embodiment of the present utility model, and these modes all will fall within protection domain of the present utility model.
