Background
Fins are generally arranged on a heat exchanger in an indoor unit of an air conditioner so as to improve the heat exchange efficiency. The fins of current heat exchangers are typically equally spaced. One or more fans are generally arranged in the indoor unit of the air conditioner, and when the fans rotate, air flows through the fins and is blown out to exchange heat. The wind speed blown out by the fan is uneven along the axial direction of the fan, and the uneven degree of the wind speed is particularly obvious along the length direction of the heat exchanger due to the resistance effect of the fins. The closer to the air outlet of the fan, the larger the wind speed. The wind speed distribution is then more complex when two or more fans are running simultaneously. Because the wind speed is not uniformly distributed, the wind speed at each position along the length of the heat exchanger has larger difference, so that the heat exchange effect at different positions of the heat exchanger has larger difference, and the whole heat exchange effect is influenced; and under the same air volume, the maximum air speed value passing through the heat exchanger is too high, so that the running noise is larger.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The three spatial directions of the indoor unit of the air conditioner are respectively the length direction, the height direction and the thickness direction. The length direction refers to the direction from one end of the casing of the indoor unit to the other end. The thickness direction is the direction perpendicular to the wall surface when the air-conditioning indoor unit is installed beside the wall. The other three-dimensional direction of the air-conditioning indoor unit is the height direction. The length direction of the air outlet window on the casing also refers to the direction from one end of the air outlet window to the other end of the air outlet window. The width direction of the air outlet window is vertical to the length direction of the air outlet window. The normal plane of the air outlet window is vertical to the plane of the two side edges of the air outlet window. Fig. 1 is an airflow distribution diagram of an equal-sheet-pitch indoor air conditioner in the prior art, which is located in the middle of an air outlet window in the width direction and on a normal plane of the air outlet window when the equal-sheet-pitch indoor air conditioner runs, wherein the equal-sheet-pitch indoor air conditioner is a simulation of a current common indoor air conditioner and is provided with two fans which are arranged at intervals; the equal fin distance means that the distance between any two adjacent fins in the air conditioner indoor unit is equal. The distance between two adjacent fins in the indoor unit of the air conditioner is 1.8 mm. Fig. 2 is a schematic diagram of wind speed distribution 150mm away from the wind outlet window, which is obtained by fitting the air flow distribution in fig. 1. In fig. 2, the abscissa is the position along the length direction of the air outlet window, the ordinate is the wind speed, and the unit of the wind speed is m/s.
As can be seen from fig. 1 and 2, at the same distance from the air outlet window: the closer to the air outlet of the fan, the larger the air speed, the farther from the air outlet of the fan, the smaller the air speed; the wind speed difference of each part of the wind outlet window is large, wherein the highest wind speed is 2.66m/s, the lowest wind speed is 1.23m/s, and the average wind speed is 2.06 m/s. The highest wind speed is 30% higher than the average wind speed, and the highest wind speed is more than 2 times of the lowest wind speed, so that the highest wind speed is higher under the condition of the same air output, the operation noise is higher, and the heat exchange is uneven.
Referring to fig. 3 to 5, an air conditioning indoor unit 100 according to the present invention will now be described. The air-conditioning indoor unit 100 comprises a casing 11, a heat exchanger 13 and a fan 12, wherein the fan 12 and the heat exchanger 13 are both arranged in the casing 11, and the fan 12 and the heat exchanger 13 are supported by the casing 11. An air outlet window 110 is formed in the casing 11, and the air outlet window 110 extends along the length direction of the casing 11. The fan 12 is arranged on one side of the heat exchanger 13 departing from the air outlet window 110, so that when the fan 12 rotates, air flow can be driven to pass through the heat exchanger 13 for heat exchange and then be blown out from the air outlet window 110. The heat exchanger 13 includes a plurality of fins 131, and the fins 131 are distributed along the length direction of the casing 11, so that when the air flow passes through the fins 131, the heat exchange can be accelerated, and the heat exchange efficiency can be improved. Along the length direction of the casing 11, the distribution density of the fins 131 at the air outlet adjacent to the fan 12 is greater than the distribution density of the fins 131 at the air outlet far away from the fan 12; that is, at each position on the length of the whole air outlet window 110, the position close to the air outlet of the fan 12, the fins 131 are arranged more densely, and at the position far from the air outlet of the fan 12, the fins 131 are arranged sparsely, that is, the distance between the corresponding fins 131 at each position is arranged at non-equal distance on the length of the whole air outlet window 110. Thus, among the fins 131 in the position close to the outlet of the fan 12: the distance between two adjacent fins 131 is smaller, that is, the distance between two adjacent fins 131 close to the air outlet of the fan 12 is smaller; some of the fins 131 at a position away from the air outlet of the fan 12: the distance between two adjacent fins 131 is larger, that is, the distance between two adjacent fins 131 far away from the air outlet of the fan 12 is larger. The resistance of the fins 131 to the air is larger near the air outlet of the fan 12, and the resistance of the fins 131 to the air is smaller far from the air outlet of the fan 12, so that the airflow discharged by the fan 12 can flow more to both sides, and the displacement far from the air outlet of the fan 12 is increased, that is, the wind speed far from the air outlet of the fan 12 in the length direction of the indoor unit 100 of the air conditioner is increased, and the wind speed near the air outlet of the fan 12 in the length direction of the indoor unit 100 of the air conditioner is reduced, so that the maximum wind speed of the air discharged from the indoor unit 100 of the air conditioner is reduced, and the minimum wind speed is increased under the same wind quantity, and the wind speed of the air discharged from each position in. Because the air speed of the air outlet at each position in the length direction of the indoor unit 100 of the air conditioner is more uniform, the heat exchange efficiency at each position of the heat exchanger 13 is more consistent, the heat exchange effect is more uniform, and the heat exchange quantity is larger and the heat exchange effect is better under the same air quantity. Under the same air quantity, the highest air speed is reduced, so that the noise is lower.
In the air conditioning indoor unit 100 of the above embodiment, the distribution density of the fins 131 at the air outlet of the heat exchanger 13 adjacent to the fan 12 is set to be greater than the density of the fins 131 at the air outlet far from the fan 12, and the distances between the fins 131 at each position along the length direction of the casing 11 are non-equidistant, that is, the distance between the adjacent fins 131 at the air outlet of the adjacent fan 12 is set to be smaller, and the distance between the adjacent fins 131 at the air outlet far from the fan 12 is set to be larger, so that the air flow resistance at the air outlet of the fan 12 can be increased by the fins 131, and a larger amount of air is blown out from the fins 131 at the position far from the fan 12, so as to reduce the air speed at the air outlet of the fan 12 adjacent to the air outlet of the air outlet window 110, and increase the air speed at the air outlet of the air outlet window 110 far from, when the air quantity is the same, the heat exchange quantity is larger, the highest air speed value is reduced, and the running noise can be further reduced.
In one embodiment, referring to fig. 6, a distance between two adjacent fins 131 adjacent to the air outlet of the fan 12 is L1, that is, among the corresponding fins 131 adjacent to the air outlet of the fan 12: the distance between two adjacent fins 131 is L1, and the value range of L1 is 1mm-1.85mm, that is, the distance L1 between two adjacent fins 131 ranges from 1mm-1.85 mm. So as to ensure the heat exchange efficiency at the air outlet of the fan 12. The distance between two adjacent fins 131 far away from the air outlet of the fan 12 is 1.5mm-3.5mm, that is, among the fins 131 corresponding to the air outlet far away from the fan 12: the distance between two adjacent fins 131 ranges from 1.5mm to 3.5 mm. And, the distance L1 between two adjacent fins 131 near the air outlet of the fan 12 is smaller than the distance between two adjacent fins 131 far from the air outlet of the fan 12. That is, the distance between two adjacent fins 131 in the plurality of fins 131 corresponding to the air outlet close to the fan 12 is L1, and the distance between two adjacent fins 131 in the plurality of fins 131 corresponding to the air outlet far from the fan 12 is D, then D is greater than L1, and the range of D is 1.5mm-3.5 mm. Therefore, the good heat exchange efficiency and the good air outlet speed at the air outlet of the fan 12 can be ensured, the air outlet speed far away from the air outlet of the fan 12 can be increased, and the heat exchange efficiency far away from the air outlet of the fan 12 is increased. In some embodiments, L1 is 1mm, and accordingly D may be 1.5mm, 1.8mm, 2.0mm, or 2.5 mm. When L1 is 1.2mm, D may be 1.5mm, 1.8mm, 2.0mm or 2.2 mm. When L1 is 1.5mm, D may be 1.8mm, 2.0mm, 2.5mm or 2.8 mm. When L1 is 1.8mm, D may be 2.0mm, 2.2mm, 2.5mm, 3.0mm or 3.5 mm. In one embodiment, referring to fig. 3 to 5, at least two fans 12 are arranged in the casing 11 along the length direction of the casing 11, and two adjacent fans 12 are arranged at intervals. At least two fans 12 are disposed in the casing 11, so that each fan 12 can be made smaller, and the driving power for rotating each fan 12 can be reduced. And wind speed distribution can be performed better. In this embodiment, two fans 12 are disposed in the casing 11. In other embodiments, only one fan 12 may be disposed in the cabinet 11. In still other embodiments, three, four, etc. other numbers of fans 12 may be disposed in the enclosure 11.
In one embodiment, referring to fig. 3 to 5, among the fins 131 between the air outlets of two adjacent fans 12: the spacing between two adjacent fins 131 is L2, the value range of L2 is 1.5mm-3.5mm, and L2 is greater than L1. In two adjacent fans 12, because the air flows blown out by the two fans 12 all have partial diffusion flow to the corresponding position between the two fans 12, however, the air flow is not larger than the air flow at the air outlet of the fan 12, so that the distance L2 between the adjacent fins 131 between the air outlets of the two fans 12 is set relatively large, and the air outlet speed in this region can be increased. In some embodiments, if L1 is 1mm, then L2 may be 1.5mm, 1.8mm, or 2.0 mm. When L1 is 1.5mm, L2 may be 1.8mm, 2.0mm, 2.2mm or 2.5 mm. When L1 is 1.8mm, L2 may be 2.0mm, 2.2mm, 2.5mm or 2.7 mm.
In two adjacent fans 12, the fins 131 corresponding to the air outlets of the two fans 12 are fins 131 far away from the air outlet of the fan 12 for any one fan 12. Therefore, the fins 131 corresponding to the air outlets far away from the fans 12 actually include the corresponding fins 131 between the two adjacent air outlets of the fans 12 and the fins 131 between the end of the air outlet 110 and the adjacent air outlets of the fans 12.
In one embodiment, referring to fig. 3 to 5, a distance between two adjacent fins 131 in the corresponding fins 131 from each end of the air outlet 110 to the fan 12 adjacent to the end is L3, that is, in the corresponding fins 131 from any end of the air outlet 110 to the fan 12 adjacent to the end: the distance between two adjacent upper fins 131 is L3, and the value range of L3 is 1.5mm-3.5mm, namely the distance L3 between two adjacent upper fins 131 ranges from 1.5mm-3.5 mm. L3 is more than or equal to L2, that is, the distance L3 between two adjacent fins 131 in the corresponding plurality of fins 131 from any end of the air outlet window 110 to the fan 12 adjacent to the end is larger than the distance L2 between two adjacent fins 131 in the plurality of fins 131 between the air outlets of two adjacent fans 12. Because the air flows blown by the two fans 12 will partially diffuse and flow to the corresponding position between the two fans 12, and the air flow diffused by the fan 12 generally only between any end of the air outlet window 110 and the fan 12 adjacent to the end will flow to the position, so that the air flow between two adjacent fans 12 is relatively large, and thus, the distance L2 between two adjacent fins 131 in the plurality of fins 131 between the air outlets of two adjacent fans 12 is relatively small, so that the air outlet speed at each position of the indoor unit 100 of the air conditioner is more uniform. In some embodiments, if L2 is 1.5mm, L3 may take 1.5mm, 1.7mm, 2.0mm, or 2.2 mm. When L2 is 1.8mm, L3 may be 2.0mm, 2.2mm, 2.5mm or 2.8 mm. L2 is 2.0mm, then L3 may be 2.2mm, 2.5mm, 3.0mm or 3.5 mm.
In the above embodiment, the above L2 and the above L3 satisfy the formula: L3-L2 is more than or equal to 0.2mm and less than or equal to 1.5 mm. The distance L2 between two adjacent fins 131 in the plurality of fins 131 between the air outlets of two adjacent fans 12, and the distance L3 between two adjacent fins 131 in the plurality of fins 131 corresponding from any end of the air outlet window 110 to the fan 12 adjacent to the end satisfy the formula: L3-L2 is more than or equal to 0.2mm and less than or equal to 1.5 mm. Because the air flow distribution and the wind speed of the outlet air of the indoor air conditioner 100 are very complex, the number of the fins 131 in the heat exchanger 13 is large, the indoor air conditioner 100 has many models, different sizes and different power, the fans 12 are often different, the heat exchanger 13 is different, if the indoor air conditioner 100 is arranged at a distance, a lot of time and energy are needed for simulation, and not to mention that product verification is needed after manufacturing. Through the empirical formula summarized by years of creative work of the inventor, the difference between the distance L2 between two adjacent fins 131 in the plurality of fins 131 between the air outlets of two adjacent fans 12 and the distance L3 between two adjacent fins 131 in the plurality of fins 131 corresponding from any end of the air outlet window 110 to the fan 12 adjacent to the end can be better determined, and further, the distance L2 between two adjacent fins 131 in the plurality of fins 131 between the air outlets of two adjacent fans 12 and the distance L3 between two adjacent fins 131 in the plurality of fins 131 corresponding from any end of the air outlet window 110 to the fan 12 adjacent to the end can be more conveniently selected, so that the arrangement and setting of the positions of the fins 131 at each position in the whole length direction of the heat exchanger 13 are facilitated, and the processing and manufacturing are facilitated.
Further, in the above embodiment, L2 has a value in the range of 1.5mm to 2.2 mm. That is, the distance L2 between two adjacent fins 131 in the plurality of fins 131 between the air outlets of two adjacent fans 12 ranges from 1.5mm to 2.2mm, so as to further reduce the difficulty in selecting and setting the distance L2 between two adjacent fins 131 in the plurality of fins 131 between the air outlets of two adjacent fans 12, and improve the distribution design and arrangement efficiency of the fins 131 in the area between the air outlets of two adjacent fans 12. Of course, the distance L3 between two adjacent fins 131 in the plurality of fins 131 corresponding to the space between any end of the air outlet window 110 and the fan 12 adjacent to the end can be conveniently selected and set by combining with the empirical formula of 0.2mm or more and L3-L2 or more and 1.5mm or less, so that the design and arrangement efficiency of the fins 131 is improved.
Further, in the above embodiment, L3 has a value in the range of 1.7mm to 3.5 mm. That is, the distance L3 between two adjacent fins 131 in the plurality of fins 131 corresponding between any end of the air outlet window 110 and the fan 12 adjacent to the end is 1.7mm to 3.5mm, so as to further reduce the difficulty in selecting the distance L3 between two adjacent fins 131 in the plurality of fins 131 corresponding between any end of the air outlet window 110 and the fan 12 adjacent to the end, and improve the distribution design and arrangement efficiency of the fins 131 in the region from any end of the air outlet window 110 to the fan 12 adjacent to the end. Of course, the design method can be combined with the empirical formula of 0.2mm or more and L3-L2 or more and 1.5mm or less to facilitate selection and setting of the distance L2 between two adjacent fins 131 in the plurality of fins 131 between the air outlets of two adjacent fans 12, so as to improve the design and arrangement efficiency of the fins 131.
Further, in the above embodiment, the value range of L2 is 1.5mm to 2.2mm, and the value range of L3 is 1.7mm to 3.5mm, which can be combined by an empirical formula of 0.2mm to 1.5mm, L3 to L2, so as to further reduce the difficulty in setting the distance between the fins 131 and the position of the fins 131 in the corresponding area on the side of each fan 12, and improve the efficiency of designing and arranging the positions of the fins 131.
Further, in the above embodiment, the above L1 and the above L2 satisfy the formula: L2-L1 is more than or equal to 0.2mm and less than or equal to 1 mm. The distance between two adjacent fins 131 at the air outlet of the adjacent fan 12 is L1, and the distance between two adjacent fins 131 in the plurality of fins 131 between the air outlets of two adjacent fans 12 is L2, which satisfies the formula: L2-L1 is more than or equal to 0.2mm and less than or equal to 1 mm. Because the air flow distribution and the wind speed of the outlet air of the indoor air conditioner 100 are very complex, the number of the fins 131 in the heat exchanger 13 is large, the indoor air conditioner 100 has many models, different sizes and different power, the fans 12 are often different, the heat exchanger 13 is different, if the indoor air conditioner 100 is arranged at a distance, a lot of time and energy are needed for simulation, and not to mention that product verification is needed after manufacturing. Through the empirical formula summarized by years of creative work of the inventor, the difference between the distance between two adjacent fins 131 at the air outlet of the adjacent fan 12 and the distance L2 between two adjacent fins 131 in the plurality of fins 131 between the air outlets of the adjacent fans 12 can be better determined, and further, the distance L2 between two adjacent fins 131 in the plurality of fins 131 between the air outlets of the adjacent fans 12 and the distance L1 between two adjacent fins 131 at the air outlet of the adjacent fan 12 can be more conveniently selected, so that the arrangement and the setting of the positions of the fins 131 at each position in the whole length direction of the heat exchanger 13 are facilitated, and the processing and the manufacturing are convenient.
In addition, the distance between the fins 131 at each position on the heat exchanger 13 can be more conveniently determined by combining the five types of the fins with the value ranges of 0.2mm to L3-L2 being less than or equal to 1.5mm, 0.2mm to L2-L1 being less than or equal to 1mm, L1 being 1mm to 1.85mm, L2 being 1.5mm to 2.2mm and L3 being 1.7mm to 3.5mm through the formula, so that the design and the arrangement are convenient, and the efficiency is improved.
In an embodiment, for some air conditioning indoor units 100, when the distance between two adjacent fans 12 is large, for example, when the distance between two adjacent fans 12 is greater than twice the distance between any end of the air outlet window 110 and the adjacent fan 12, the sheet distance between the corresponding fins 131 on two sides of each fan 12 may be set independently as needed, and the sheet distance between the corresponding fins 131 between two fans 12 is not necessarily set to be smaller than the sheet distance between one end of the air outlet window 110 and the corresponding fins 131 between the adjacent fans 12.
In one embodiment, among the fins 131 between the air outlets of two adjacent fans 12: the distance L2 between any two adjacent fins 131 is equal, so as to facilitate the processing and manufacturing, facilitate the position design and layout of the fins 131 between the air outlets of two adjacent fans 12, and facilitate the processing and manufacturing at the same time.
In one embodiment, the spacing L1 between any two adjacent fins 131 adjacent to the air outlet of the fan 12 is equal. Because the air outlet of the fan 12 is generally relatively uniform, the distance L1 between any two adjacent fins 131 at the air outlet of the adjacent fan 12 is equal, so that the air outlet of the adjacent fan 12 is also relatively uniform, the position design and layout of the fins 131 at the air outlet of the adjacent fan 12 are convenient, and the processing and manufacturing can be convenient.
In one embodiment, the distance L3 between any two adjacent fins 131 of the plurality of corresponding fins 131 between each end of the air outlet window 110 and the fan 12 adjacent to the end is equal, so as to facilitate the position design and layout of the fins 131 between each end of the air outlet window 110 and the fan 12 adjacent to the end, and facilitate the manufacturing.
In one embodiment, each fin 131 is a flat sheet, so as to facilitate processing and manufacturing, and at the same time, the air outlet resistance of each fin 131 on the heat exchanger 13 is determined, so as to facilitate position design and layout of the fins 131, and facilitate processing and manufacturing.
Referring to fig. 4 and 5, fig. 4 is a diagram illustrating an airflow distribution on a plane parallel to the length direction of the outlet window 110 and located at the middle of the width direction when the indoor unit 100 of an air conditioner operates according to an embodiment of the present invention. In this embodiment, a distance L1 between any two adjacent fins 131 at the air outlet of the adjacent fan 12 is 1.8mm, a distance L3 between any two adjacent fins 131 in the plurality of corresponding fins 131 between each end of the air outlet 110 and the fan 12 adjacent to the end is 2.2mm, and a distance L2 between any two adjacent fins 131 in the plurality of fins 131 between the air outlets of two adjacent fans 12 is 2.0 mm. Fig. 5 is a schematic diagram of wind velocity distribution with a distance of 150mm from the wind outlet window 110, which is obtained by fitting the wind velocity distribution in fig. 4. In fig. 5, the abscissa is the position along the length direction of the air outlet window 110, the ordinate is the wind speed, and the unit of the wind speed is m/s. As can be seen from fig. 4 and 5, in the air-conditioning indoor unit 100, the maximum wind speed is 2.40m/s, the minimum wind speed is 1.37m/s, and the average wind speed is 2.06 m/s. The air outlet speed of the indoor unit 100 of the air conditioner is more uniform.

Because the number of the fins 131 arranged on the heat exchanger 13 is large, in the design process, if the position design is carried out one by one, a large amount of time is needed, meanwhile, the adjustment is needed according to a simulation experiment, and then, the adjustment is carried out again after the product experiment verification, so that a large amount of time and labor energy are needed. The plurality of fins 131 corresponding to the space between each end of the air outlet window 110 and the fan 12 adjacent to the end are divided into at least two groups along the length direction of the air outlet window 110, the distance between any two adjacent fins 131 in each group of fins 131 is equal, and after the distance between any two adjacent fins 131 in each group of fins 131 is selected, the position and arrangement of the whole group of fins 131 can be determined, so that the design and arrangement are convenient, and the processing and manufacturing are convenient. The plurality of corresponding fins 131 between each end of the air outlet window 110 and the fan 12 adjacent to the end are grouped along the length direction of the air outlet window 110, the distance between any two adjacent fins 131 in each group of fins 131 is equal, although the farther the structure is from the adjacent fan 12, the smaller the corresponding air outlet speed is, the smaller the change of the wind speed is to the overall average wind speed of the group of fins 131, the smaller the overall influence is, and therefore, the influence on the overall heat exchange effect and the air output is smaller, but the design can greatly improve the design and arrangement of the fins 131, the processing and manufacturing are convenient, the design and manufacturing efficiency is greatly improved, the manufacturing of installation equipment of the fins 131 is convenient, and the cost is reduced. Of the adjacent two sets of fins 131: the distance L31 between two adjacent fins 131 in the group of fins 131 close to the corresponding end of the air outlet window 110 is greater than or equal to the distance L32 between two adjacent fins 131 in the other group of fins 131, and this structure can increase the air outlet speed at the group of fins 131 far from the adjacent fan 12, so that the air outlet speed from each end of the air outlet window 110 to the area between the adjacent fans 12 is more uniform.
Further, in an embodiment, when the distance between each end of the air outlet window 110 and the adjacent fan 12 is short, the distance between any two adjacent fins 131 in the plurality of fins 131 between each end of the air outlet window 110 and the adjacent fan 12 may be set to be equal, that is, when the distance between two adjacent fans 12 is short, the distance between two adjacent fins 131 in any one group of fins 131 is set to be equal to the distance between two adjacent fins 131 in another group of fins 131, which is convenient for processing and manufacturing.

Of course, in some embodiments, the lengths of the fins 131 may be set differently, and the distance between the fins may be set differently, so that the wind speed from the end of the wind outlet window 110 to the fan 12 adjacent to the end is more uniform and closer to the wind speed at the wind outlet of the fan 12.
Of course, in some embodiments, the distance between two adjacent fins 131 gradually increases from the air outlet adjacent to the fan 12 to the air outlet far away from the fan 12. The structural layout mode can set the positions of the fins 131 more specifically, so that the air outlet speed of each position of the indoor unit 100 of the air conditioner is more uniform.

Because the number of the fins 131 arranged on the heat exchanger 13 is large, in the design process, if the position design is carried out one by one, a large amount of time is needed, meanwhile, the adjustment is needed according to a simulation experiment, and then, the adjustment is carried out again after the product experiment verification, so that a large amount of time and labor energy are needed. The plurality of fins 131 between the air outlets of the two adjacent fans 12 are divided into at least three groups along the length direction of the air outlet window 110, the distance between any two adjacent fins 131 in the group of fins 131 is equal, and after the distance between any two adjacent fins 131 in the group of fins 131 is selected, the position and arrangement of the whole group of fins 131 can be determined, so that the design and the arrangement are convenient.

Referring to fig. 7, in an embodiment, when the distance between two adjacent fans 12 is larger, the distance L22 between two adjacent fins 131 of one group of fins 131 near the middle position of two fans 12 is preferably set to be larger than the distance L21 between two adjacent fins 131 of the other group of fins 131 in two adjacent groups of fins 131.
