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

[0063] 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.

[0064] This embodiment provides an air conditioner. Figure 1-Figure 10 The 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.

[0065] 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.

[0066] 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.

[0067] 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 .

[0068] 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.

[0069] 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.

[0070] 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 .

[0071] 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 .

[0072] 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.

[0073] 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.

[0074] 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 .

[0075] 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.

[0076] 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.

[0077] 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 .

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] In order to solve the above problems, an embodiment of the present disclosure proposes an air conditioner 1000 .

[0085] 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.

[0086] 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.

[0087] 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.

[0088] In some embodiments, the fins may be configured as aluminum fins.

[0089] In some embodiments, the refrigerant pipeline can be configured as a copper pipe.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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 .

[0094] 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.

[0095] 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.

[0096] In some embodiments, the guide portion 40 may include a guide portion 43 , and the guide portion 43 is recessed relative to the body portion 10 .

[0097] In some embodiments, the guide portion 40 may include a first connection portion 45, which is disposed between the drainage portion 43 and the pipe hole 20, and the first connection portion 45 connects the main body portion 10 and the drainage portion 43. The first connection portion 45 and the drainage portion 43 are disposed along a third direction, and the third direction is substantially the same as the height direction of the casing.

[0098] In some embodiments, the first connection portion 45 is not perpendicular to the main body portion 10 , so that the connection between the first connection portion 45 and the main body portion 10 is relatively smooth, which can facilitate the drainage of condensed water to the first connection portion 45 .

[0099] In some embodiments, the drainage portion 43 is configured as a planar plate, and the plane where the drainage portion 43 is located is substantially parallel to the plane where the main body portion 10 is located.

[0100] In some embodiments, the distance between the two points of the drainage portion 43 that are farthest apart in the third direction on the orthographic projection on the plane parallel to the third direction is defined as L. p , define the distance between the two points of the guide portion 40 that are farthest apart in the third direction on the orthographic projection on the plane parallel to the third direction as L d .

[0101] When L p :L dIf the length of the drainage portion 43 in the third direction is too small, the angle formed by the first connection portion 45 and the main body 10 is too small, and the angle formed by the first connection portion 45 and the drainage portion 43 is too small, so that the first connection portion 45 slows down the drainage speed of the condensed water around the pipe hole 20 of the fin, thereby weakening the enhancement of the drainage effect of the drainage portion 40 on the fin. p :L d The first length ratio is greater than or equal to the first length ratio. The first length ratio is any value between 0.6 and 0.7, and the first length ratio can be 0.6, 0.65, or 0.7, so as to increase the drainage speed of the condensed water around the pipe hole 20 of the fin by the first connecting portion 45, thereby improving the effect of the guide portion 40 on fin drainage.

[0102] When L p :L d If L is too large, the length of the drainage portion 43 in the third direction will be too large, the angle formed by the first connection portion 45 and the main body 10 will be too large, and the angle formed by the first connection portion 45 and the drainage portion 43 will be too large. The condensed water around the pipe hole 20 cannot be smoothly drained to the drainage portion 43 through the first connection portion 45, thereby deteriorating the fin drainage effect. Therefore, L p :L d Less than or equal to the second length ratio, the second length ratio is any value between 0.75-0.8, and the second length ratio can be 0.75, or 0.78, or 0.8.

[0103] In this embodiment, L p :L d The value range of is reasonably selected, so that after the first connecting part 45 is connected to the first guide part 40, it is convenient to drain the condensed water around the pipeline hole 20, thereby improving the drainage effect of the condensed water accumulated around the pipeline hole 20 and reducing the wind resistance of the first heat exchanger 1001.

[0104] In some embodiments, the guide portion 40 further includes a third connection portion 41, which is disposed on one side of the guide portion 43 in the second direction, and the third connection portion 41 connects the body portion 10 and the guide portion 43 respectively, and the first direction and the second direction are perpendicular to each other. The third connection portion 41 can be connected to the first connection portion 45.

[0105] The third connection portion 41 is used to guide the condensed water on the main body 10 to the drainage portion 43 through the third connection portion 41 .

[0106] In some embodiments, the third connection portion 41 may be configured as a flat plate, and the plane where the third connection portion 41 is located is tilted relative to the plane where the main body portion 10 is located.

[0107] In some embodiments, the plane where the third connection portion 41 is located is not perpendicular to the plane where the main body portion 10 is located.

[0108] In some embodiments, the plane where the third connection portion 41 is located is inclined relative to the plane where the drainage portion 43 is located.

[0109] In some embodiments, the guide portion 40 further includes a fourth connection portion 42, which is arranged relative to the third connection portion 41 in the second direction, and the fourth connection portion 42 is respectively connected to the main body portion 10 and the guide portion 43, and the fourth connection portion 42 can be connected to the first connection portion 45. The fourth connection portion 42 is used to guide the condensed water on the main body portion 10 to the guide portion 43 through the fourth connection portion 42.

[0110] In some embodiments, the fourth connection portion 42 may be configured as a planar plate, and the plane where the fourth connection portion 42 is located is tilted relative to the plane where the main body portion 10 is located.

[0111] In some embodiments, the plane where the fourth connection portion 42 is located is not perpendicular to the plane where the main body portion 10 is located.

[0112] In some embodiments, the plane where the fourth connecting portion 42 is located is inclined relative to the plane where the drainage portion 43 is located.

[0113] The distance between the two points of the drainage portion 43 that are farthest apart in the second direction on the orthographic projection on the plane parallel to the second direction is defined as W. b4 , the distance between the two points of the guide portion 40 that are farthest apart in the second direction on the orthographic projection on the plane parallel to the second direction is defined as W b3 .

[0114] When W b4 :W b3 If the width of the drainage portion 43 is too small, the angle formed by the third connection portion 41 and the main body 10 is too small, and the angle formed by the fourth connection portion 42 and the main body 10 is too small, which will slow down the flow of condensed water on the second direction side of the drainage portion 43 through the third connection portion 41 and the fourth connection portion 42, and reduce the speed of the third connection portion 41 and the fourth connection portion 42 draining condensed water, thereby reducing the drainage effect of the fins. Therefore, W b4 :W b3 Greater than or equal to the first width ratio. The first width ratio is any value between 0.2 and 0.3, and the first width ratio can be 0.2, 0.25, or 0.3.

[0115] When W b4 :W b3If it is too large, the width of the drainage portion 43 will be too large, the angle formed by the third connection portion 41 and the main body 10 will be too large, and the angle formed by the fourth connection portion 42 and the main body 10 will be too large, making it difficult for the condensed water to smoothly reach the flat part of the guide structure, thereby slowing down the condensed water discharge speed and weakening the drainage effect of the fins. Therefore, W b4 :W b3 Less than or equal to the second width ratio. The second width ratio is any value between 0.35 and 0.5, and the second width ratio may be 0.35, 0.4, or 0.5.

[0116] In some embodiments, the guide portion 40 further includes a second connection portion 44 , the second connection portion 44 is connected to the drainage portion 43 and is disposed opposite to the first connection portion 45 , and the second connection portion 44 is connected to the main body portion 10 .

[0117] The second connection portion 44 is disposed below the drainage portion 43 , and is used to drain the condensed water on the drainage portion 43 .

[0118] In some embodiments, the second connection portion 44 is not perpendicular to the main body 10 , so that the connection between the second connection portion 44 and the main body 10 is relatively smooth, which can facilitate the condensed water to be drained from the drainage portion 43 .

[0119] In some embodiments, the drainage portion 43 is disposed in the middle of the guide portion 40, which facilitates the third connection portion 41 and the fourth connection portion 42 to evenly and effectively drain the condensed water on both sides of the fin to the drainage portion 43, and helps the first connection portion 45 and the second connection portion 44 to continuously discharge the condensed water around the pipe hole 20 and the condensed water in the drainage portion 43.

[0120] 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, connect the main body portion 10, and at least one single bridge portion 30 is arranged on one side of the drainage portion 43 along the second direction.

[0121] 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.

[0122] 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 second 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.

[0123] 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 may protrude from the main body 10 in the first direction. The connecting plate 33 may increase the contact area between the fin and the air, thereby improving the heat exchange efficiency between the air and the fin.

[0124] In some embodiments, single bridge portions 30 are respectively disposed on both sides of the air guide portion 40 in the second direction.

[0125] In some embodiments, the distance between the two points of the fin that are farthest apart in the second direction and the orthographic projection on the plane parallel to the second direction is defined as W. f .

[0126] When W b3 :W f If it is too small, the width of the guide portion 40 will be too small, which will weaken the collection effect of the third connecting portion 41 and the fourth connecting portion 42 on the condensed water on both sides of the fin, resulting in a decrease in the drainage effect of the fin, or even worsening the drainage effect of the fin. b3 :W f The third width ratio is greater than or equal to the third width ratio, and the third width ratio is any value between 0.06 and 0.15. The third width ratio can be 0.06, 0.1, or 0.15.

[0127] When W b3 :W f If W is too large, the width of the guide portion 40 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 too low structural strength of the fin at this location, which may cause problems such as fin cracking. b4 :W b3 Less than or equal to the fourth width ratio, the fourth width ratio is any value between 0.2-0.3. The fourth width ratio can be 0.2, 0.25, or 0.3.

[0128] In some embodiments, the distance between the two points of the connecting plate 33 that are farthest apart in the second direction and the orthographic projections on the plane parallel to the second direction is defined as W. b2 .

[0129] When W b2 :W f If the width of the second connection portion 44 is too small, the width of the second connection portion 44 will be too small, which will weaken the heat exchange effect between the second connection portion 44 and the air. If the width of the second connection portion 44 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 fGreater 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, or 0.1, or 0.2.

[0130] When W b2 :W f If W is too large, the width of the second connecting portion 44 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 too low structural strength of the fin at this location, which may cause problems such as fin cracking. b2 :W f Less than or equal to the sixth width ratio, the sixth width ratio is any value between 0.3-0.42, and the sixth width ratio may be 0.3, or 0.4, or 0.42.

[0131] In some embodiments, the distance between the two points closest to each other on the drainage portion 43 and the main body portion 10 in the first direction on the orthographic projection on the plane parallel to the first direction is defined as H. d .

[0132] When H d If the distance between the drainage portion 43 and the main body 10 is too small, there will be insufficient space for the drainage and collection of condensed water, resulting in poor fin drainage effect. d Greater than or equal to the first distance, the first distance is any value between 0.2-0.3, and the first distance can be 0.2, or 0.25, or 0.3.

[0133] When H d If it is too large, the distance between the guide part 43 and the main body 10 will be too large, and the guide part 43 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 air volume and a decrease in the performance of the first heat exchanger 1001. d Less than or equal to the second distance, the second distance is any value between 0.35-0.4, and the second distance can be 0.35, or 0.38, or 0.4.

[0134] 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.

[0135] In some embodiments, the guide portion 40 is located in the middle of the fin in the second 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.

[0136] 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, or L f ≥15mm, or L f ≥17mm.

[0137] 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 ≤18mm, or L f ≤20mm, or L f ≤21mm.

[0138] 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 ≥4 mm, or D f ≥4.5mm, or D f ≥5mm.

[0139] In some embodiments, when the pipe hole 20 of the fin is larger, the cost of the refrigerant pipe increases. f ≤6mm, or D f ≤7mm, or D f ≤8mm.

[0140] 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, or W f ≥10mm, or W f ≥15mm.

[0141] 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 ≤16mm, or W f ≤20mm, or Wf ≤22mm.

[0142] In some embodiments, the fin is defined as having a first circle, the first circle and the pipe hole 20 are concentric circles, and the diameter of the first circle is defined as D b , define the diameter of the pipeline hole 20 as D f In order to make the length of the guide portion 40 not too large, D b ≥1.5D f , or D b ≥1.6D f , or D b ≥1.7D f .

[0143] In some embodiments, in order to prevent the length of the guide portion 40 from being too small. b ≤1.8D f , or D b ≤1.9D f , or D b ≤2.0D f .

[0144] In some embodiments, a single bridge portion 30 includes two spoilers, which are an upper spoiler 31 and a lower spoiler 32. The upper spoiler 31 is arranged on the upper side of the single bridge portion 30, the lower spoiler 32 is arranged on the lower side of the single bridge portion 30, and the connecting plate 33 connects the two spoilers.

[0145] In some embodiments, the upper spoiler 31 and the lower spoiler 32 are respectively set as plane plates, the plane where the upper spoiler 31 is located is inclined with the plane where the main body 10 is located, and the angle between the plane where the upper spoiler 31 is located and the plane where the main body 10 is located is defined as α1, and the plane where the lower spoiler 32 is located is inclined with the plane where the main body 10 is located, and the angle between the plane where the lower spoiler 32 is located and the plane where the main body 10 is located is defined as α2. α1 can be substantially the same as the angle of α2, which is conducive to uniform spoiling of air when it flows through the first heat exchanger 1001.

[0146] In some embodiments, when α1 and α2 are 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 exchange of the first heat exchanger 1001. Therefore, α1≥20°, or α1≥30°, or α1≥40°; α2≥20°, or α2≥30°, or α2≥40°.

[0147] In some embodiments, when α1 and α2 are too large, the wind resistance when the air flows 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. Therefore, α1≤50°, or α1≤60°, or α1≤70°; α2≤50°, or α2≤60°, or α2≤70°.

[0148] In some embodiments, the distance between the two points closest to each other on the connecting plate 33 and the main body 10 in the first direction on the orthographic projection on the plane parallel to the first direction is defined as H. b .

[0149] 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. b Greater than or equal to the third distance, the third distance is any value between 0.4mm-0.6mm, and the third distance can be 0.4mm, or 0.5mm, or 0.6mm.

[0150] When H b When it is too large, the distance between the guide part 43 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 Less than or equal to the fourth distance, the fourth distance is any value between 0.7mm-1.0mm, and the fourth distance can be 0.7mm, or 0.8mm, or 1.0mm.

[0151] In some embodiments, the shortest distance between the single bridge portion 30 and the edge of the fin in the second direction is defined as W. b1 .

[0152] 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, or (W b1 :W f )≥0.08, or (W b1 :W f )≥0.1.

[0153] When W b1 :W fWhen 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 )≤0.15, or (W b1 :W f )≤0.2, or (W b1 :W f )≤0.25.

[0154] In some embodiments, a line connecting the centers of two pipe holes 20 on the same fin is defined as a first line, a first connecting line is defined as a straight line at the connection between the upper spoiler 31 and the main body 10, and an angle between the first connecting line and the first line is defined as β1. A second connecting line is defined as a straight line at the connection between the lower spoiler 32 and the main body 10, and an angle between the second connecting line and the first line is defined as β2. It can be set that β1 is approximately equal to β2.

[0155] In some embodiments, the first connecting line is tangent to the first circle it is close to.

[0156] In some embodiments, the second connecting line is tangent to the first circle it is close to.

[0157] In some embodiments, the values ​​of β1 and β2 can be determined based on the parameter L f , W b1 , W b2 and D b to determine the value of .

[0158] In some embodiments, the distance between the two points of the upper spoiler 31 and the lower spoiler 32 that are farthest apart in the third direction 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 .

[0159] In some embodiments, a third connecting line and a fourth connecting line are formed at the connection between the first connecting portion 45 and the main body portion 10, and the third connecting line is tangent to the first circle close to it, and the fourth connecting line is tangent to the first circle close to it, so as 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.

[0160] In some embodiments, the parameter L d The value of can be determined according to the parameter W b3 and D b to determine the value of .

[0161] In some embodiments, the third connecting portion 41 is a flat plate, and the plane where the third connecting portion 41 is located is inclined with the plane where the main body 10 is located, and the angle between the plane where the third connecting portion 41 is located and the plane where the main body 10 is located is defined as θ1; the fourth connecting portion 42 is a flat plate, and the plane where the fourth connecting portion 42 is located is inclined with the plane where the main body 10 is located, and the angle between the plane where the fourth connecting portion 42 is located and the plane where the main body 10 is located is defined as θ2.

[0162] θ1 is approximately equal to θ2, which helps the third connecting portion 41 and the fourth connecting portion 42 to evenly and effectively drain the condensed water on both sides of the fin to the drainage portion 43. The values ​​of θ1 and θ2 can be determined according to W b3 and W b4 to be sure.

[0163] In some embodiments, the values ​​of θ1 and θ2 can be determined based on W b3 , W b4 and H d to be sure.

[0164] In some embodiments, at least a portion of the first connecting portion 45 is a planar plate, and the angle between the plane where the planar plate portion of the first connecting portion 45 is located and the plane where the main body portion 10 is located is γ1; at least a portion of the second connecting portion 44 is a planar plate, and the angle between the plane where the planar plate portion of the second connecting portion 44 is located and the plane where the main body portion 10 is located is γ2.

[0165] γ1 is substantially equal to γ2, which not only helps the first connection portion 45 and the second connection portion 44 to continuously discharge the condensed water around the pipe hole 20 and the condensed water at the drainage portion 43, but also helps to improve the versatility and convenience of the fin.

[0166] In some embodiments, the values ​​of γ1 and γ2 can be based on L d , L p and W b4 To determine, when L d , L p and W b4 After determination, the values ​​of γ1 and γ2 can be determined.

[0167] In the height direction of the casing, that is, the third direction, 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.

[0168] 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.

[0169] The third connection part 41 and the fourth connection part 42 enable the condensed water around the slit of the single bridge part 30 to flow to the drainage part 43 at an accelerated speed. The first connection part 45 enables the condensed water flowing from the outer surface of the refrigerant pipeline to the pipeline hole 20 of the fin and the condensed water flowing around the pipeline hole 20 of the fin along the gravity direction to flow smoothly to the drainage part 43. Furthermore, the condensed water can smoothly flow downward through the second connection part 44 in the drainage part 43. The utility model accelerates the flow of condensed water by setting the guide part 40, so that the residual water amount on the surface of the fin is reduced.

[0170] The discharge of condensed water can be roughly divided into three stages. The first stage is approximately between 0 and 0.5s. During this stage, the condensed water is discharged at the fastest speed. Compared with the original fins, the drainage rate of the optimized fins in this application is significantly improved, and the volume fraction of residual water on the fin surface is reduced by about 11%. The second stage is approximately between 0.5 and 1s. During this stage, the discharge rate of condensed water decreases slightly. Compared with the original fins, the drainage rate of the optimized fins is basically the same, and the volume fraction of residual water on the fin surface is reduced by about 12%. The third stage is approximately between 1 and 3s. During this stage, the discharge 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 volume fraction of residual water on the fin surface is reduced by about 11%.

[0171] 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.

[0172] 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.
