Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art

[0002] Air conditioners are widely used to adjust indoor temperature. Air conditioners include indoor units and outdoor units. The indoor units are usually installed indoors and can be used to exchange heat with indoor air. The outdoor units are installed outdoors and can be used to exchange heat in the refrigerant with outdoor air.

[0003] When the air conditioner is in cooling mode, the temperature of the cold surface of the indoor heat exchanger is lower than the dew point temperature of the air, which will cause the water vapor in the air to liquefy and precipitate on the cold surface of the indoor heat exchanger. If the condensed water on the cold surface of the indoor heat exchanger cannot be discharged in time, the distance between the fins will be reduced or even completely blocked, causing the wind resistance of the heat exchanger to increase, resulting in a decrease in air volume at the same fan speed.

[0004] The fin type commonly used in indoor heat exchangers is single-bridge fins, which have a high heat transfer coefficient and can achieve good heat exchange effects. However, the slit structure of the single-bridge fins will cause serious water accumulation on the surface of the heat exchanger when condensed water is precipitated under refrigeration conditions, increasing the wind resistance of the heat exchanger and reducing the heat transfer coefficient, thereby reducing the heat exchange capacity of the heat exchanger and the performance of the air conditioner.

DETAILED DESCRIPTION

[0065] Some embodiments of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments provided by the present disclosure are within the scope of protection of the present disclosure.

[0066] This embodiment provides an air conditioner. Figure 1-Figure 10The air conditioner 1000 may include an air conditioner indoor unit 100 and an air conditioner outdoor unit 200. The air conditioner indoor unit 100 is installed in an indoor space. The air conditioner outdoor unit 200 is installed in an outdoor space for heat exchange with an outdoor environment.

[0067] The air conditioner indoor unit 100 includes a casing, which is arranged in the indoor space. A first cavity is arranged in the casing. A heat exchange air inlet is arranged on the casing, and the heat exchange air inlet is communicated with the indoor space.

[0068] The casing is provided with a heat exchange air outlet, the heat exchange air outlet is connected to the indoor space, and the heat exchange air inlet and the heat exchange air outlet are connected to the first cavity.

[0069] The air-conditioning indoor unit 100 may include a first heat exchanger 1001 , in which refrigerant flows. The refrigerant can be used to exchange heat with air entering the first cavity and flowing through the first heat exchanger 1001 .

[0070] In some embodiments, the housing has a top and a bottom, and the height direction of the housing is from the bottom of the housing to the top of the housing. The housing also has a width direction, wherein the width direction of the housing is from one side of the housing in the left-right direction to the other side thereof. The housing has a front side and a rear side that are arranged oppositely, and the front side, the rear side, the left side, and the right side of the housing are the circumferential sides of the housing.

[0071] In some embodiments, the air conditioner outdoor unit 200 is disposed in an outdoor space, and the air conditioner outdoor unit 200 includes a housing, a second cavity is disposed in the housing, and an outdoor air inlet and an outdoor air outlet are disposed on the housing. The outdoor air inlet is connected to the outdoor space and the second cavity, and the outdoor air outlet is connected to the outdoor space and the second cavity.

[0072] In some embodiments, an outdoor heat exchanger 202 is disposed in the shell, and refrigerant flows in the outdoor heat exchanger 202 . The refrigerant in the outdoor heat exchanger 202 can be used to exchange heat with the air entering the second cavity and flowing through the outdoor heat exchanger 202 .

[0073] In some embodiments, a compressor 201 is disposed in the shell, the compressor 201 is disposed in the second chamber, and the compressor 201 is installed at the bottom of the air-conditioning outdoor unit 200 .

[0074] In some embodiments, the air-conditioning outdoor unit 200 may include a throttling device 204, which is disposed in the second cavity and is used to expand the liquid refrigerant in a high-temperature and high-pressure state into a low-pressure liquid refrigerant. The throttling device 204 may be disposed on the leeward side of the outdoor heat exchanger 202, and may be conveniently connected to the compressor 201.

[0075] The air conditioner 1000 performs a refrigeration cycle of the air conditioner 1000 by using the compressor 201, the outdoor heat exchanger 202, the throttling device 204 and the first heat exchanger 1001. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0076] The compressor 201 compresses the low-temperature and low-pressure refrigerant gas and discharges the high-temperature and high-pressure refrigerant gas. The discharged refrigerant gas flows into the outdoor heat exchanger 202 .

[0077] The outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0078] The throttling device 204 expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the outdoor heat exchanger 202 into a low-pressure liquid-phase refrigerant.

[0079] The first heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 201 .

[0080] The first heat exchanger 1001 can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0081] In both the first heat exchanger 1001 and the outdoor heat exchanger 202, one is a condenser and the other is an evaporator. When the first heat exchanger 1001 is used as a condenser and the outdoor heat exchanger 202 is used as an evaporator, the air conditioner 1000 is used as a heater in a heating mode. When the first heat exchanger 1001 is used as an evaporator and the outdoor heat exchanger 202 is used as a condenser, the air conditioner 1000 is used as a cooler in a cooling mode.

[0082] In some embodiments, a fan may be provided in the first cavity, and the fan may be used to drive the indoor air into the first cavity through the heat exchange air inlet, and then flow through the first heat exchanger 1001, and flow into the room after passing through the heat exchange air outlet. It may be provided that the fan is provided on the leeward side of the first heat exchanger 1001 to reduce the resistance of the first heat exchanger 1001 to the air flow and increase the air intake into the room.

[0083] The blower may include a motor and a fan. The drive shaft of the motor is connected to the fan. The fan is driven by the motor to rotate to drive the air in the first chamber to flow.

[0084] When the air conditioner 1000 is in cooling mode, the temperature of the cold surface of the first heat exchanger 1001 is lower than the dew point temperature of the air, which causes the water vapor in the air to liquefy and precipitate on the cold surface of the first heat exchanger 1001. If the condensed water on the cold surface of the first heat exchanger 1001 cannot be discharged in time, the distance between the fins will be reduced or even completely blocked, resulting in an increase in the wind resistance of the heat exchanger, thereby reducing the air volume at the same fan speed.

[0085] The fin type commonly used in the first heat exchanger 1001 is a single-bridge fin, which has a high heat transfer coefficient and can achieve a good heat transfer effect. However, the slit structure of the single-bridge fin will cause serious water hanging on the surface of the first heat exchanger 1001 when condensed water is precipitated under refrigeration conditions, which increases the wind resistance of the first heat exchanger 1001 and reduces the heat transfer coefficient, thereby reducing the heat transfer amount of the first heat exchanger 1001 and the performance of the air conditioner 1000.

[0086] In order to solve the above problems, an embodiment of the present disclosure proposes an air conditioner 1000 .

[0087] In some embodiments, the first heat exchanger 1001 may be disposed in the air-conditioning indoor unit 100 , and the first heat exchanger 1001 may include a refrigerant pipeline, and refrigerant flows inside the refrigerant pipeline.

[0088] In some embodiments, the first heat exchanger 1001 may include fins, which are arranged on the periphery of the refrigerant pipeline and connected to the refrigerant pipeline. Through the heat transfer between the fins and the refrigerant pipeline, the temperature of the refrigerant pipeline can be transferred to the fins, and the contact area with the air is increased by the fins, thereby improving the heat exchange efficiency of the first heat exchanger 1001.

[0089] In some embodiments, a plurality of fins may be provided, and the plurality of fins are distributed around the periphery of the refrigerant pipeline, and gaps are provided between adjacent fins. Air may flow through the first heat exchanger 1001 through the gaps and exchange heat with the fins.

[0090] In some embodiments, the fins may be configured as aluminum fins.

[0091] In some embodiments, the refrigerant pipeline can be configured as a copper pipe.

[0092] In some embodiments, the fin may include a body portion 10, which is the main body of the fin. The body portion 10 may be configured in a plate shape.

[0093] In some embodiments, the body 10 can be configured as a flat plate, and the plane where the body 10 is located is parallel to the height direction of the housing. The body 10 is disposed along the height direction of the housing.

[0094] In some embodiments, the fin may include a pipeline hole 20, which is disposed on the body 10 and is configured as a through hole that penetrates the body 10. The refrigerant pipeline is provided with the pipeline hole 20 so that the fin is disposed at the periphery of the refrigerant pipeline.

[0095] In some embodiments, the edge of the pipeline hole 20 may be provided with a flange structure to facilitate the connection between the refrigerant pipeline and the pipeline hole 20 .

[0096] In some embodiments, the fin may include a guide portion 40 , which is disposed below the pipe hole 20 . The guide portion 40 may facilitate drainage of condensed water on the fin.

[0097] Under the action of gravity, condensed water is easily accumulated at the connection between the pipe hole 20 on the fin and the refrigerant pipe. Arranging the guide part 40 below the pipe hole 20 can make it easier to drain the condensed water accumulated at the connection of the refrigerant pipe, thereby reducing the wind resistance of the first heat exchanger 1001.

[0098] In some embodiments, the guide portion may include a first diverter portion 41 , the first diverter portion 41 is connected to the main body portion, and the first diverter portion 41 is protruding from the main body portion.

[0099] In some embodiments, the guide portion may include a second diverter portion 42 connected to the main body portion, and the first diverter portion 41 and the second diverter portion 42 are arranged in parallel along a first direction, and the first direction is parallel to the horizontal direction.

[0100] In some embodiments, the guide portion may include a first guide portion 46 , which is connected to the main body portion and is disposed between the first diverter portion 41 and the pipeline hole.

[0101] The first guide portion 46 is used to guide the condensed water at the pipeline hole to the first diversion portion 41 and the second diversion portion 42 , and the condensed water is guided to the main body through the first diversion portion 41 and the second diversion portion 42 .

[0102] The first diversion portion 41 and the second diversion portion 42 divert the condensed water on the guide portion to both sides, and the condensed water gathers at the bottom of the first diversion portion 41 and the second diversion portion 42. Under the action of gravity, the condensed water can flow downward quickly to achieve the effect of reducing the amount of residual water on the surface of the fin, thereby avoiding the fins being blocked by the condensed water and improving the heat exchange effect of the first heat exchanger.

[0103] The first guide portion 46 is not perpendicular to the main body 10 , so that the connection between the first guide portion 46 and the main body 10 is relatively smooth, which facilitates the condensed water to flow through the first guide portion 46 to the first diversion portion 41 and the second diversion portion 42 .

[0104] The fin includes at least two guide portions, which are arranged in parallel along the first direction, and a trough portion 43 is formed between adjacent guide portions. The first diverter portion 41 and the second diverter portion 42 can divert condensed water to the trough portion 43 .

[0105] The first diversion portion 41 and the second diversion portion 42 allow the condensed water on the guide portion to flow quickly to the trough portion 43. As the condensed water gradually gathers in the trough portion 43, its gravity gradually increases, causing the condensed water to flow downward at a faster speed, thereby reducing the amount of residual water on the fin surface. The guide portion accelerates the flow of condensed water on the fin by collecting and draining the condensed water.

[0106] In some embodiments, the guide portion may include a second guide portion 45 , the second guide portion 45 is connected to the main body portion, and the second guide portion 45 and the first guide portion 46 are respectively disposed on two opposite sides of the first diverter portion 41 .

[0107] The second guide portion 45 is not perpendicular to the main body, so that the connection between the second guide portion 45 and the main body is relatively smooth, which can facilitate the condensed water to be guided to the main body along the second guide portion 45 after passing through the first diversion portion 41 and the second diversion portion 42, avoiding the accumulation of condensed water in the trough portion 43, and improving the guiding effect of the condensed water.

[0108] In some embodiments, the number of guide portions on the fin is set to n, and n can be any value between 2 and 5. n can be 2, that is, n≥2, so that the number of guide portions is not too small, the number of trough portions 43 formed is not too small, and the trough portions 43 can form a drainage effect on the condensed water, which can improve the drainage effect of the guide portion on the condensed water.

[0109] n can be 5, that is, n≤5, which can ensure that the number of guides is not too large, the guides are not too dense, the number of troughs 43 formed is not too large, and the distance between adjacent troughs 43 is not too small. If the distance between adjacent troughs 43 is too small, condensed water will accumulate in the troughs 43 and be difficult to discharge, which will deteriorate the drainage effect of the fins. Too many guides on the fins will cause excessive wind resistance of the fins, thereby causing air volume attenuation and reduced heat exchange performance of the heat exchanger. n≤5 can improve the drainage effect of the guides on condensed water.

[0110] In some embodiments, the guide portion is located between the two pipe holes of the fin. In the first direction, the guide portion is located in the middle of the first direction of the fin, which helps to collect condensed water on both sides of the fin and condensed water around the pipe holes of the fin and discharge them smoothly.

[0111] In some embodiments, in some embodiments, the fin is defined to have a first circle 50, the first circle 50 and the pipe hole 20 are concentric circles, and the diameter of the first circle 50 is defined as D b, define the diameter of the pipeline hole 20 as D f .

[0112] Among them, D b =(1.5~2.0)D f When D b <1.5D f When the diameter of the first circle 50 is too small, the size of the guide part between the pipeline holes will be set too large, which is not conducive to the diversion of condensed water around the pipeline holes. b ≥1.5D f , which can improve the guiding effect of the guide part on the condensed water and prevent the condensed water from accumulating on the fins.

[0113] In some embodiments, when D b >2.0D f When the diameter of the first circle 50 is too large, the size of the guide part between the pipeline holes will be set too small, and the guide part will have a poor effect of guiding the condensed water around the pipeline holes. Therefore, D b ≤2.0D f , which can improve the guiding effect of the guide part on the condensed water and prevent the condensed water from accumulating on the fins.

[0114] In some embodiments, a third connecting line is formed at the connection between the first guide portion 46 and the main body portion 10, and the third connecting line is tangent to the first circle 50 close thereto to adapt to the change in wind speed direction when air flows through the edge of the duct hole 20 of the fin, thereby reducing the influence of the fin structure on wind resistance.

[0115] In some embodiments, a fourth connecting line is formed at the connection between the second guide portion 45 and the main body, and the fourth connecting line is tangent to the first circle 50 close thereto to adapt to the change in wind speed direction when air flows through the edge of the duct hole 20 of the fin, thereby reducing the influence of the fin structure on wind resistance.

[0116] In some embodiments, the first diversion portion 41 and the second diversion portion 42 are connected at one side of the main body, and an edge formed by connecting the first diversion portion 41 and the second diversion portion 42 is defined as a first connecting edge 44 .

[0117] The distance between the two farthest points on the orthographic projection of the first connecting edge 44 on the plane where the main body is located is defined as L. p , define the distance between the two farthest points of the guide part on the plane where the main body is located as L c .

[0118] Among them, L p :L cGreater than or equal to the first length ratio, the first length ratio can be any value between 0.6 and 0.8, the first length ratio can be 0.6, when the first length ratio is less than 0.6, the length of the first connecting edge 44 is too small, the angle between the plane where the first guide portion 46 is located and the plane where the main body is located is too small, the angle between the plane where the second guide portion 45 is located and the plane where the main body is located is too small, so that the first guide portion 46 weakens the drainage effect of the condensed water around the pipe hole of the fin, and the second guide portion 45 slows down the drainage speed of the condensed water in the trough portion 43, thereby weakening the drainage effect of the guide portion on the fin, so the first length ratio is set to be greater than or equal to 0.6.

[0119] In some embodiments, L p :L c Less than or equal to the second length ratio, the second length ratio can be any value between 0.8 and 0.9, the second length ratio can be 0.9, when the second length ratio is greater than 0.9, the length of the first connecting edge 44 is too large, the angle between the plane where the first guide portion 46 is located and the plane where the main body is located is too large, the angle between the plane where the second guide portion 45 is located and the plane where the main body is located is too large, so that the condensed water around the pipe hole cannot be smoothly drained into the trough portion 43 through the first guide portion 46, so that the drainage effect of the first guide portion 46 on the fin is weakened, and the condensed water in the trough cannot be smoothly drained to the main body through the second guide portion 45, thereby weakening the drainage effect of the guide portion on the fin, so the second length ratio is set to be less than or equal to 0.9.

[0120] In some embodiments, the shortest distance between the first connecting edge 44 and the plane where the main body is located is H c , H c The first spacing is greater than or equal to the first spacing, which can be any value between 0.2 mm and 0.4 mm, and can be set to 0.2 mm. When the first spacing is less than 0.2 mm, it means that the distance between the first connecting edge 44 of the guide part and the plane where the main body is located is too small, and the guide part does not have enough space to collect and drain the condensed water, which leads to poor drainage effect of the fin. Therefore, the first spacing is set to be greater than or equal to 0.2 mm.

[0121] In some embodiments, H c The second spacing is less than or equal to the second spacing, which can be any value between 0.3mm-0.4mm. The second spacing can be set to 0.4mm. When the second spacing is greater than 0.4mm, it means that the distance between the first connecting edge 44 of the air guide and the plane where the main body is located is too large, causing the wind resistance of the fin to increase greatly, resulting in air volume attenuation and reduced performance of the indoor heat exchanger. Therefore, the second spacing is set to be less than or equal to 0.4mm.

[0122] In some embodiments, in the first direction, the distance between the two farthest points of the first diversion portion 41 on the orthographic projection of the plane where the main body portion is located is W c1 The distance between the two points of the guide part that are farthest apart in the first direction on the plane parallel to the first direction is defined as W. c2 , W c1 =0.5W c2 , which is conducive to evenly collecting and draining the condensed water to both sides of the guide part, and smoothly discharging the condensed water.

[0123] In some embodiments, the plane where the main body is located is parallel to the first direction.

[0124] In some embodiments, the distance between the two points of the fin that are farthest apart in the first direction and the orthographic projection on the plane parallel to the first direction is defined as W. f .

[0125] In some embodiments, W c2 :W f The first width ratio is greater than or equal to the first width ratio, and the first width ratio can be any value between 0.1 and 0.2. The first width ratio can be set to 0.1. When the first width ratio is less than 0.1, the width of the guide portion in the first direction is too small, the trough portion 43 is too dense, and the condensed water accumulated in the trough portion 43 is difficult to drain, resulting in poor fin drainage effect. Therefore, the first width ratio is greater than or equal to 0.1.

The second width ratio can be set to 0.25. When the second width ratio is greater than 0.25, the width of the guide portion in the first direction will be too large, and the distance between the guide portion and the fin surface will be too small, so that the strength of the fin in the single bridge portion is too small, resulting in the fin being prone to cracking and other defects.

[0127] In some embodiments, L c The value of can be determined based on the number of guide parts n, the position of the guide parts on the main body, the size parameter W of the guide parts c2 and the diameter D of the first circle 50 b It is jointly determined that it is beneficial to fully utilize the fin area to drain the condensate.

[0130] In some embodiments, the first angle θ 1 and the second angle θ 2 The specific value can be determined according to the dimension parameter W of the guide part. c1 , the dimension parameter W of the guide part c2 , the size parameter H of the guide part c Sure.

[0131] In some embodiments, the first guide portion 46 is configured as a flat plate, and the angle between the plane where the first guide portion 46 is located and the plane where the main body portion is located is a third angle γ. 1 The angle between the plane where the second guide portion 45 is located and the plane where the main body is located is the fourth angle γ 2 , the third angle γ 1 Equal to the fourth angle γ 2 , which helps the first guide part 46 to continuously discharge the condensed water around the pipe holes of the fin, and the second guide part 45 to continuously discharge the condensed water in the trough part 43.

[0132] In some embodiments, the third angle γ 1 and the fourth angle γ 2 The specific value can be determined according to the position of the third connecting line and the fourth connecting line, the guide part size parameter W c1 、Dimensional parameters of the guide part W c2 , guide part size parameter L c , guide part size parameter L p , guide part size parameter H c to be sure.

[0133] In some embodiments, the fin may include a single bridge portion 30, which may protrude from the main body portion 10 in the first direction. The single bridge portion 30 connects the main body portion 10, and at least one single bridge portion 30 is arranged on one side of the guide portion along the first direction.

[0134] In some embodiments, the single bridge portion 30 is a slit structure on the main body portion 10 , and the single bridge portion 30 is integrally formed with the main body portion 10 , and the single bridge portion 30 is obtained on the main body portion 10 through a slit process.

[0135] In some embodiments, the single bridge portion 30 may include a spoiler, the spoiler is connected to the main body portion 10, and the plane where the spoiler is located is inclined relative to the first direction. The spoiler can generate wind resistance to the air flowing through the first heat exchanger 1001, thereby changing the flow direction of part of the air and having a spoiling effect on the air, thereby improving the heat exchange efficiency between the air and the fins.

[0136] In some embodiments, the single bridge portion 30 may include a connecting plate 33, the connecting plate 33 is connected to the spoiler, and the connecting plate 33 protrudes from the main body 10. The connection plate 33 can increase the contact area between the fin and the air, thereby improving the heat exchange efficiency between the air and the fin.

[0137] In some embodiments, single bridge portions 30 are respectively disposed on both sides of the guide portion in the first direction.

[0138] In some embodiments, the distance between the two points of the connecting plate 33 that are farthest apart in the first direction and the orthographic projections on the plane parallel to the first direction is defined as W. b2 .

[0139] When W b2 :W f If the width of the connecting plate is too small, the width of the connecting plate will be too small, which will weaken the heat exchange effect between the connecting plate and the air. If the width of the connecting plate is too small, the structural strength of the single bridge portion 30 will be too small, which will cause problems such as cracking of the single bridge portion 30. b2 :W f The fifth width ratio is greater than or equal to the fifth width ratio, the fifth width ratio is any value between 0.05-0.2, and the fifth width ratio can be 0.05, so as to enhance the structural strength of the single bridge portion 30 and improve the heat exchange effect between the single bridge portion and the air.

[0140] When W b2 :W f If W is too large, the width of the connecting plate will be too large, and the distance between the guide portion 40 and the single bridge portion 30 on the fin surface will be too small, resulting in the structural strength of the fin being too weak at this point, which may cause problems such as fin cracking. b2 :W f The sixth width ratio is less than or equal to the sixth width ratio, and the sixth width ratio is any value between 0.3 and 0.42. The sixth width ratio may be 0.42 to enhance the structural strength of the single bridge portion 30 and improve the heat exchange effect between the single bridge portion and the air.

[0141] In some embodiments, two pipe holes 20 are provided on the fin, and the guide portion 40 is located between the two pipe holes 20 of the fin, which is conducive to collecting and draining the condensed water around the pipe holes 20 of the fin and smoothly discharging the condensed water from the fin.

[0142] In some embodiments, the guide portion 40 is located in the middle of the fin in the first direction, that is, the guide portion 40 is located in the middle of the width direction of the fin, which is conducive to collecting and draining condensed water on both sides of the width direction of the fin.

[0143] In some embodiments, the distance between the centers of two pipe holes 20 on the fin is defined as L. f , when L f The smaller the L, the denser the refrigerant pipelines will be. The gap space in the first heat exchanger 1001 will become smaller, and the wind resistance of air flowing through the first heat exchanger 1001 will increase, which is not conducive to the heat exchange between the air and the fins and the first heat exchanger 1001. Therefore, L f ≥13mm, which can reduce the wind resistance of air flowing through the first heat exchanger 1001 and improve the heat exchange effect between the air, the fins and the first heat exchanger 1001.

[0144] When L f When L is larger, the refrigerant pipes will be farther apart, and the gap space in the first heat exchanger 1001 will become larger, which cannot meet the heat exchange efficiency between the air and the first heat exchanger 1001, and is not conducive to the heat exchange between the air and the fins and the first heat exchanger 1001. Therefore, L f ≤24mm, which can improve the heat exchange efficiency between the air and the first heat exchanger 1001.

[0145] In some embodiments, the inner diameter of the pipe hole 20 defining the fin is D f When the pipe hole 20 of the fin is smaller, it will affect the heat exchange effect of the refrigerant pipe, which is not conducive to the heat exchange of the first heat exchanger 1001. Therefore, D f ≥4mm, can improve the heat exchange effect of the refrigerant pipeline.

[0146] In some embodiments, when the pipe hole 20 of the fin is larger, the cost of the refrigerant pipe increases. f ≤8mm, which can reduce the cost of refrigerant pipelines and balance the heat exchange effect.

[0147] In some embodiments, when the width of the fin is too small, that is, W f If the value is too small, the width of the fin will be too small, which cannot meet the heat exchange efficiency between the air and the first heat exchanger 1001, and is not conducive to the heat exchange between the air, the fin and the first heat exchanger 1001. Therefore, W f ≥9mm, which can improve the heat exchange between air, the fins and the first heat exchanger 1001.

[0148] In some embodiments, when the width of the fin is too large, that is, W f When the width of the fin is too large, the fin width will be too large. The oversized fin will cause the efficiency of the first heat exchanger 1001 to be unable to increase with the W. f The increase in W increases the fin cost.f ≤22mm, which can reduce the fin cost and optimize the heat exchange efficiency of the first heat exchanger 1001.

[0149] In some embodiments, a single bridge portion 30 includes two spoilers, which are an upper spoiler 32 and a lower spoiler 31. The upper spoiler 32 is arranged on the upper side of the single bridge portion 30, the lower spoiler 31 is arranged on the lower side of the single bridge portion 30, and the connecting plate 33 connects the two spoilers.

[0150] In some embodiments, the upper spoiler 32 and the lower spoiler 31 are respectively configured as plane plates, and the plane where the upper spoiler 32 is located is inclined to the plane where the main body 10 is located, and the angle between the plane where the upper spoiler 32 is located and the plane where the main body 10 is located is defined as α. 1 The plane where the lower spoiler 31 is located is inclined with the plane where the main body 10 is located, and the angle between the plane where the lower spoiler 31 is located and the plane where the main body 10 is located is defined as α 2 α 1 Can be used with α 2 The angles are roughly the same, which is beneficial for the air to be evenly disturbed when flowing through the first heat exchanger 1001.

[0151] In some embodiments, when α 1 and α 2 If the value is too small, the disturbance effect of the upper spoiler and the lower spoiler on the incoming air will be reduced, and the heat transfer coefficient of the fin will be low, which is not conducive to the heat transfer of the first heat exchanger 1001. Therefore, α 1 ≥20°, α 2 ≥20°, can improve the heat transfer effect of the fins.

[0152] In some embodiments, when α 1 and α 2 When α is too large, the wind resistance of the air flowing through the single bridge portion 30 will be too large, increasing the wind resistance of the first heat exchanger 1001 and reducing the air volume flowing through the first heat exchanger 1001. 1 ≤70°, α 2 ≤70° can reduce the wind resistance when air flows through the single bridge portion 30.

[0153] In some embodiments, the distance between the two closest points between the connecting plate 33 and the main body 10 is defined as H. b .

[0154] When H b If the value is too small, the distance between the connecting plate 33 and the main body 10 will be too small, which will weaken the turbulence effect of the single bridge on the incoming air flow and increase the heat exchange area of ​​the fins less, which is not conducive to heat exchange. bThe third distance is greater than or equal to the third distance, the third distance is any value between 0.4 mm and 0.6 mm, and the third distance can be 0.4 mm. The third distance is greater than or equal to 0.4 mm, which can increase the heat exchange area of ​​the fin and facilitate heat exchange.

[0155] When H b When it is too large, the distance between the connecting plate 33 and the main body 10 will be too large, and the connecting plate 33 will protrude from the main body 10, which will increase the wind resistance when the air flows through the fins, resulting in a decrease in the air volume and a decrease in the performance of the first heat exchanger 1001. b The fourth distance is less than or equal to the fourth distance, the fourth distance is any value between 0.7 mm and 1.0 mm, and the fourth distance can be 1.0 mm. When the fourth distance is less than or equal to 1.0 mm, the wind resistance of air flowing through the fins can be reduced, and the air volume flowing through the first heat exchanger can be increased.

[0156] In some embodiments, the shortest distance between the single bridge portion 30 and the edge of the fin in the first direction is defined as W. b1 .

[0157] When W b1 :W f If the single bridge portion 30 is too small, the distance between the single bridge portion 30 and the guide portion 40 will be too far, which is not conducive to guiding the condensed water accumulated at the single bridge portion 30 to the guide portion 40. Therefore, (W b1 :W f )≥0.05, which can facilitate the diversion of condensed water accumulated at the single bridge portion 30 to the diversion portion 40.

[0158] When W b1 :W f When the single bridge portion 30 is too large, the distance between the single bridge portion 30 and the guide portion 40 will be too far, resulting in a weak strength between the single bridge portion and the guide portion, and the fin cracking and other undesirable phenomena are prone to occur. Therefore, (W b1 :W f )≤0.25, which can enhance the structural strength between the bridge part and the guide part.

[0159] In some embodiments, the line connecting the centers of the two pipe holes 20 on the same fin is defined as the first line, the connection between the upper spoiler 32 and the main body 10 is defined as a first connecting line, the first connecting line is a straight line, and the angle between the first connecting line and the first line is defined as β 1 The connection between the lower spoiler 31 and the main body 10 forms a second connection line, the second connection line is a straight line, and the angle between the second connection line and the first line is β 2 . The setting is, β 1 Roughly equal to β 2 .

[0160] In some embodiments, the first connecting line is tangent to the first circle 50 it is close to.

[0161] In some embodiments, the second connecting line is tangent to the first circle 50 it is close to.

[0162] In some embodiments, β 1 and β 2 The value of can be determined according to the parameter L f , W b1 , W b2 and D b to determine the value of .

[0163] In some embodiments, the distance between the two points on the main body of the upper spoiler 32 and the lower spoiler 31 that are farthest apart is defined as L. b , L b The value of can be determined according to the parameter L f , W b1 , W b2 and D b to determine the value of .

[0164] In the height direction of the casing, the upper and lower air guide portions 40 of the fins can be symmetrically arranged, thereby improving the commonality level of the fins and improving the installation efficiency.

[0165] Since condensed water is more likely to accumulate at the bottom of the first heat exchanger 1001, the guide portion 40 can be appropriately adjusted within the range of the above parameters from the top to the bottom of the first heat exchanger 1001 to ensure that the drainage performance of the fins at the bottom of the first heat exchanger 1001 is stronger than the drainage performance of the fins at the top of the first heat exchanger 1001, thereby improving the overall drainage effect of the first heat exchanger 1001.

[0166] The first guide portion 46 allows the condensed water flowing from the outer surface of the refrigerant pipeline to the periphery of the pipeline holes 20 of the fins and the condensed water flowing around the pipeline holes 20 of the fins along the direction of gravity to flow smoothly to the first diversion portion 41 and the second diversion portion 42. The first diversion portion 41 and the second diversion portion 42 allow the condensed water on the guide portion to be diverted to both sides. The condensed water gathers at the bottom of the first diversion portion 41 and the second diversion portion 42. Under the action of gravity, the condensed water can flow downward quickly to reduce the amount of residual water on the surface of the fins, thereby avoiding the fins being blocked by condensed water and improving the heat exchange effect of the first heat exchanger.

[0167] The utility model accelerates the flow of condensed water by providing the guide part 40, so that the residual water amount on the surface of the fin is reduced.

[0168] The discharge of condensed water can be roughly divided into three stages. The first stage is about 0 to 0.5s. In this stage, the condensed water flows at the fastest speed. Compared with the original fins, the drainage rate of the optimized fins in this application is significantly improved. At 0.5s, the residual water volume fraction on the fin surface is reduced by about 20%; the second stage is about 0.5 to 1.0s. In this stage, the flow rate of condensed water decreases slightly. Compared with the original fins, the drainage rate of the optimized fins is basically the same, and the residual water volume fraction on the fin surface continues to decrease by about 20%; the third stage is about 1 to 3s. In this stage, the flow rate of condensed water is further reduced. Compared with the original fins, the drainage rate of the optimized fins is basically the same, and the residual water volume fraction on the fin surface is reduced by about 20%.

[0169] The air conditioner 1000 of this embodiment can improve the water hanging phenomenon of the first heat exchanger 1001 under cooling conditions, so that the wind resistance of the first heat exchanger 1001 is reduced, the air volume is increased, and the heat exchange coefficient is improved, thereby achieving more sufficient heat exchange and increased heat exchange between the air and the first heat exchanger 1001.

[0170] In the air conditioner 1000 of this embodiment, since the air guide part 40 generates certain disturbances to the incoming air, the turbulence of the airflow can be enhanced, thereby increasing the heat transfer coefficient of the fins and improving the heat transfer performance of the first heat exchanger 1001.
