In order to solve the problem that the heat exchange efficiency and the heat exchange capacity of an air conditioner in the prior art are lower, the application provides an air conditioner.
As shown in fig. 1 to 3, the air conditioner includes a heat exchanger body 10, a fan 20, a flow guiding structure 30, and an air duct shielding mechanism. Wherein a plurality of fans 20 are sequentially arranged. The flow guiding structure 30 is disposed between the heat exchanger body 10 and the fans 20, and one end of the flow guiding structure 30, which is close to the fans 20, has air channels 31 corresponding to the fans 20 one by one. The shutter 41 of the air duct shutter mechanism is capable of entering at least one air duct 31 to shut off the communication state of the heat exchanger body 10 with the corresponding blower 20.
In the operation process of the air conditioner, the air channels 31 are arranged in one-to-one correspondence with the fans 20, and the air flow discharged from the heat exchanger body 10 enters the corresponding fans 20 through the air channels 31 in the flow guiding structure 30, and is discharged to the outside through the action of the fans 20.
When a part of fans 20 need to be closed (fans 20 stop running), a shielding piece 41 of an air duct shielding mechanism is operated to enter an air duct 31 corresponding to the closed fans 20, so that the air duct 31 is blocked, the fans 20 corresponding to the air duct 31 are disconnected from the heat exchanger body 10, and the phenomenon that air flow (air quantity) loss and cross flow phenomenon are avoided when air flow discharged from the heat exchanger body 10 cannot enter the closed fans 20 through the air duct 31 and enter the corresponding fans 20 through the air duct 31 which is not shielded is avoided because air flow vortex and air inlet resistance increase caused by opening of inlets of the fans 20 which are not started is avoided, and accordingly the air flow discharged from the heat exchanger body 10 enters the fans 20 through the air duct 31 which is not shielded is ensured; when all fans 20 are required to operate, the shielding piece 41 of the air duct shielding mechanism is withdrawn from the shielded air duct 31, the fan 20 corresponding to the air duct 31 is communicated with the heat exchanger body 10, and air flow discharged from the heat exchanger body 10 can enter the fan 20 through the air duct 31 to realize air outlet. Therefore, compared with the condition that the air duct of the fan which does not run in the prior art is not closed, the air conditioner in the embodiment does not cause air loss, and further the heat exchange efficiency and the heat exchange capacity of the air conditioner are improved.
In this embodiment, through optimizing the structure of the air conditioner, the diversion structure 30 has the function of adjusting the inflow and air distribution according to the combined work of different fans 20, so as to improve the heat exchange efficiency and the heat exchange capability of the air conditioner when part of fans 20 are operated.
Optionally, the number of shutters 41 is one or more, and different shutters 41 may selectively block the same or different air ducts 31 at the same time. As shown in fig. 1 to 4, in the present embodiment, there are two shutters 41, and the two shutters 41 can selectively block the same or different air ducts 31 at the same time. Like this, above-mentioned setting can guarantee that shielding member 41 can realize the shielding to the wind channel 31 that corresponds of a fan 20 or two fans 20, and then guarantees that shielding member 41 can satisfy the whole operating mode of air conditioner, guarantees the operational reliability of wind channel shielding structure.
In other embodiments not shown in the drawings, the shield is slidably connected to the flow guiding structure. Specifically, the shielding piece is provided with a roller or a pulley, and the guide structure is correspondingly provided with a guide rail. When part of fans in the air conditioner do not run, the shielding piece is required to shield the air channel corresponding to the fans, the shielding piece is operated to move on the guide rail, the shielding piece enters into the air channel to shield the air channel, further loss of air quantity caused by air flow discharged from the heat exchanger body entering into the non-running fans is prevented, and heat exchange efficiency and heat exchange capacity of the air conditioner are improved.
As shown in fig. 1 and 2, the air duct shielding mechanism further includes a transmission mechanism 42, and the shielding member 41 is connected to the transmission mechanism 42 so that the position of the shielding member 41 can be changed. In this way, the shielding member 41 moves on the transmission mechanism 42, so that shielding or avoiding of the air duct 31 by the shielding member 41 can be realized, and disconnection or communication between the fan 20 and the heat exchanger body 10 can be further realized. The structure is simple and easy to realize.
Specifically, when the fan 20 in the air conditioner is not operated, the shielding piece 41 is operated and the shielding piece 41 moves in the transmission mechanism 42, so that shielding of the air duct 31 corresponding to the fan 20 which is not operated is achieved, the fan 20 is disconnected from the heat exchanger body 10, air flows discharged from the heat exchanger body 10 are ensured to enter the fan 20 in an operating state through the air duct 31 corresponding to the fan 20 which is operated, air exhaust operation is achieved, air flows discharged from the heat exchanger body 10 are ensured to be discharged from the fan 20, loss of air flow (air quantity) is avoided, and heat exchange efficiency and heat exchange capacity of the air conditioner are improved.
In this embodiment, the transmission mechanism 42 is disposed on the air guiding structure 30, so that the internal structure of the air conditioner is more compact and the structural layout is more reasonable.
The position setting of the transmission mechanism 42 is not limited to this, and may be set at other positions of the air conditioner.
Alternatively, when the number of the shutters 41 is plural and moves into the same air passage 31, the shutters 41 are arranged at intervals in the flow direction of the gas in the flow guiding structure 30. In this embodiment, when two shutters 41 move into the same air duct 31, each shutter 41 is disposed at intervals in the flow direction of the gas in the flow guiding structure 30. Thus, the arrangement can ensure that the shielding pieces 41 do not interfere with each other in the running process of the corresponding transmission mechanism 42, and ensure the working reliability of the air duct shielding mechanism.
In this embodiment, the shutter 41 on the side closer to the blower 20 moves preferentially over the other shutters 41. Thus, when the shielding member 41 shields the air duct 31, the shielding member 41 close to one side of the fan 20 (the air duct 31) shields the air duct 31 corresponding to the fan 20 in preference to other shielding members 41, so that the sealing performance of the shielding member 41 to the air duct 31 is better, the air flow in the flow guiding structure 30 is prevented from entering the air duct 31 to influence the air outlet quantity of the air conditioner, and the heat exchange efficiency and the heat exchange capacity of the air conditioner are improved.
As shown in fig. 2, the flow guiding structure 30 includes a collecting section 32 and a dividing section 33 in a flow direction of the gas in the flow guiding structure 30, and a plurality of partitions 50 are provided in the dividing section 33 to constitute a plurality of air channels 31. In this way, the air flow discharged from the heat exchanger body 10 sequentially passes through the flow collecting section 32 and the air dividing section 33 and then enters the fan 20, the flow collecting section 32 gathers and guides the air flow, the air dividing section 33 redistributes the air flow, and the air flow is prevented from generating turbulence in the air dividing section 33 to influence the heat exchange efficiency of the air conditioner.
As shown in fig. 1 to 3, the projection of the air outlet end face of the air collecting section 32 near one end of the air dividing section 33 in the first reference plane M is in an arc shape, the projection of the shielding member 41 in the first reference plane M is in a first arc-shaped structure, and the curvature radius of the first arc-shaped structure is the same as that of the arc shape. In this way, the above arrangement ensures on the one hand a smoother movement of the shutter 41 on the air outlet end face; on the other hand, the shielding effect of the shielding piece 41 on the air outlet of the flow guiding structure 30 is better, and the air flow is prevented from entering the air duct 31 corresponding to the non-running fan 20.
Specifically, the shielding member 41 and the transmission mechanism 42 are disposed between the air duct 31 and the air outlet end face, and in the process of moving the shielding member 41 along the transmission mechanism 42, the communication state between the air duct 31 and the heat exchanger body 10 can be cut off, and then the communication state between the fan 20 corresponding to the air duct 31 and the heat exchanger body 10 can be cut off.
Alternatively, the shutter 41 is an arc-shaped plate-like structure, and the radius of curvature of the arc-shaped plate-like structure is the same as the radius of curvature of the air-out end face. The arc-shaped plate-shaped structure has simple structure and easy processing.
In the present embodiment, the transmission mechanism 42 is provided on the air outlet end face. The arrangement makes the structure of the air duct shielding structure simpler and the assembly with the flow guiding structure easier.
As shown in fig. 1 to 3, the plurality of shutters 41 includes a first shutter 411 and a second shutter 412, the first shutter 411 moves along the air outlet end face, the second shutter 412 moves along a trajectory having a predetermined distance H from the air outlet end face, and the predetermined distance H is greater than or equal to the thickness of the first shutter 411. Thus, the arrangement can ensure that the first shielding piece 411 and the second shielding piece 412 can not interfere with each other in the moving process, and the working reliability of the air duct shielding structure is improved.
In this embodiment, the first shielding member 411 and the second shielding member 412 are used to guide the airflow and close the air duct 31 of the non-started fan 20 when the partial fan 20 is started, so as to avoid the airflow vortex and the air inlet resistance increase caused by the opening of the air duct 31 of the non-started fan 20, thereby improving the heat exchange capability and the heat exchange efficiency of the air conditioner when the partial fan 20 is operated.
As shown in fig. 1 to 3, the air conditioner further includes a support plate 60. Wherein, the projection of the support plate 60 in the first reference plane M is in a second arc structure, the curvature radius of the second arc structure is the same as that of the first arc structure, the first shielding member 411 and the second shielding member 412 are connected with the support plate 60, and the support plate 60 is connected with the collecting section 32. In this way, the above arrangement can ensure that the first shielding member 411 and the second shielding member 412 move between the support plate 60 and the air outlet end face more smoothly, continuously and continuously, and no jamming phenomenon occurs.
In the present embodiment, when all fans 20 are in communication with the heat exchanger body 10, the first and second shutters 411 and 412 are provided on the two support plates 60, respectively, and the first and second shutters 411 and 412 preferentially block the air passage 31 adjacent thereto. The number of fans 20 is three, namely a first fan 21, a second fan 22 and a third fan 23. Wherein the first fan 21 is arranged close to the second shutter 412 and the third fan 23 is arranged close to the first shutter 411.
Specifically, when all fans 20 are in a communication state with the heat exchanger body 10, the first shielding member 411 and the second shielding member 412 are respectively arranged on the two support plates 60 to avoid the air channels 31 of the three fans 20, so that the first shielding member 411 and the second shielding member 412 are prevented from affecting the normal operation of the fans 20; when one of the fans 20 (e.g., the first fan 21) is not operating, the air duct 31 of that fan 20 needs to be blocked, the second shielding member 412 is preferentially operated to block the air duct 31, the first shielding member 411 is still disposed on the support plate 60, and the arc-shaped outer surface of the second shielding member 412 guides the airflow on the surface thereof to the second fan 22 closest to the first fan 21; as shown in fig. 3, when two fans 20 (e.g., the first fan 21 and the third fan 23) are not operated, the first shielding member 411 shields the air duct 31 corresponding to the third fan 23, and the second shielding member 412 shields the air duct 31 corresponding to the first fan 21, so that the air flows discharged from the air guiding structure 30 are all discharged from the second fan 22, no loss of air flow (air volume) occurs, and compared with the air duct 31 of the fan 20 which is not operated in the prior art, the above arrangement can improve the heat exchange efficiency of the air conditioner.
As shown in fig. 1 to 3, the number of the support plates 60 is two, and projections of the two support plates 60 in the first reference plane M are respectively located at two sides of the collecting section 32. Thus, the first and second shutters 411 and 412 are provided on the two support plates 60, respectively, and the transmission mechanism 42 is provided on the air outlet end face and the support plates 60. Specifically, when the first shielding member 411 and/or the second shielding member 412 are not required to shield the air duct 31, the first shielding member 411 and the second shielding member 412 are provided on the support plate 60, and when the first shielding member 411 and/or the second shielding member 412 are required to shield the air duct 31, the first shielding member 411 and/or the second shielding member 412 move from the support plate 60 to the air outlet end face to shield the air duct 31.
The number and the installation positions of the support plates 60 are not limited to this. Alternatively, four support plates 60 are provided, with each two support plates 60 being disposed on either side of the manifold section 32.
In the present embodiment, the transmission mechanism 42 has a rack structure, and the extending direction of the rack structure is identical to the extending direction of the arc shape. Like this, rack structure sets up on the air-out terminal surface and unanimous with the projection extension direction of air-out terminal surface in first reference plane M, and then can guarantee to shelter from the piece 41 with drive mechanism 42 gear connection's air outlet on the air-out terminal surface of water conservancy diversion structure 30 fully, prevents to take place the phenomenon of air current loss, improves the heat exchange efficiency of air conditioner.
The structure of the transmission mechanism 42 is not limited to this. Alternatively, the transmission 42 is a pulley or a sliding-type bearing.
As shown in fig. 1, the minimum distance from the heat exchanger body 10 to the air outlet end face is L, and L is 20mm or more and 300mm or less. In this way, the above-mentioned distance arrangement between the heat exchanger body 10 and the air outlet end surface can strengthen the air guiding effect of the collecting section 32 and avoid an increase in flow resistance caused by too long or too short a distance.
As shown in fig. 1-3, the flow area of the manifold section 32 decreases in the direction of gas flow within the flow directing structure 30. In this way, the collecting section 32 is a cavity with a gradual change section, and guides the airflow discharged from the heat exchanger body 10, thereby improving the air outlet rate of the air conditioner.
As shown in fig. 2, the collecting section 32 is a guide wall surface, and the radius of curvature ρ of the guide wall surface and the length P of the guide wall surface satisfyTherefore, the change of the flow guide wall surface is relatively mild when the inner wall surface of the flow collecting section 32 is changed with small curvature, and the air flow in the flow collecting section 32 cannot generate vortex or turbulence, so that the air outlet efficiency of the air conditioner is improved.
As shown in fig. 2, the total air outlet area of the air outlet end of the collecting section 32 is S', the air inlet area of the air inlet end of the collecting section 32 is S, wherein,therefore, the arrangement can ensure that the inflow resistance of the flow guiding structure 30 changes in a smaller range when only part of the fans 20 are started, so as to improve the heat exchange efficiency and the heat exchange capacity of the air conditioner.
As shown in fig. 2, the air intake areas of the air ducts 31 are uniform. Specifically, the air inlet surface of each air duct 31 is a rectangular surface, and the areas of the rectangular surfaces are consistent, so that the air quantity entering each fan 20 is consistent, the air quantity discharged from the fan 20 is consistent, the air outlet uniformity of the air conditioner is improved, and the user experience is improved.
In this embodiment, the air conditioner further includes at least one driving structure, the driving structure is in driving connection with the shielding member 41, and the driving structure is disposed in one-to-one correspondence with the shielding member 41, and the driving structure is used for driving the shielding member 41 to move on the transmission mechanism 42 so as to cut off the communication state between the heat exchanger body 10 and the corresponding fan 20.
From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
in the operation process of the air conditioner, a plurality of air channels are arranged in one-to-one correspondence with a plurality of fans, and air flow discharged from the heat exchanger body enters the corresponding fans through the air channels in the flow guiding structure and is discharged to the outside through the action of the fans.
When a part of fans need to be closed (fans stop running), a shielding piece of an air duct shielding mechanism is operated to enter an air duct corresponding to the closed fans, so that the air duct is blocked, and the fans corresponding to the air duct are disconnected from the heat exchanger body, so that air flow discharged from the heat exchanger body cannot enter the closed fans through the air duct, but enters the corresponding fans through the non-shielded air duct, and therefore the air flow discharged from the heat exchanger body is ensured to enter the fans through the non-shielded air duct, loss of air flow (air quantity) and cross flow phenomenon are avoided; when all fans are required to operate, the shielding piece of the air duct shielding mechanism is withdrawn from the shielded air duct, the fan corresponding to the air duct is communicated with the heat exchanger body, and air flow exhausted from the heat exchanger body can enter the fan through the air duct to realize air outlet. Like this, compare with the wind channel of the fan that does not move among the prior art not close, the air conditioner in this application can not cause the loss of amount of wind, and then has improved the heat exchange efficiency and the heat transfer ability of air conditioner.
