[0037] Some embodiments of the present disclosure provide an air conditioner.

[0038] As shown in FIG. 1A and FIG. 1B , the air conditioner 2000 includes an outdoor unit 200 .

[0039] In some embodiments, the air conditioner 2000 further includes an indoor unit 400. The indoor unit 400 is connected to the outdoor unit 200.

[0040] In some embodiments, the air conditioner 2000 further includes a pipe 30. The indoor unit 400 and the outdoor unit 200 are connected via the pipe 30 to transmit refrigerant.

[0041] In some embodiments, the outdoor unit 200 includes a compressor 201. The compressor 201 is configured to compress refrigerant so that low-pressure refrigerant is compressed to form high-pressure refrigerant.

[0042] In some embodiments, the outdoor unit 200 further includes a first heat exchanger 203 (outdoor heat exchanger). The first heat exchanger 203 is configured to exchange heat between outdoor air and the refrigerant transmitted through the first heat exchanger 203. For example, in the cooling mode of the air conditioner 2000, the first heat exchanger 203 operates as a condenser, so that the refrigerant compressed by the compressor 201 dissipates heat to the outdoor air through the first heat exchanger 203 and condenses. In the heating mode of the air conditioner 2000, the first heat exchanger 203 operates as an evaporator, so that the decompressed refrigerant absorbs heat from the outdoor air through the first heat exchanger 203 and evaporates.

[0043] In some embodiments, the first heat exchanger 203 further includes heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the first heat exchanger 203, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0044] In some embodiments, the outdoor unit 200 further includes a first fan 204. The first fan 204 is configured to draw outdoor air into the outdoor unit 200 through the outdoor air inlet of the outdoor unit 200, and to deliver the outdoor air, after heat exchange with the first heat exchanger 203, through the outdoor air outlet of the outdoor unit 200. The first fan 204 provides power for the flow of outdoor air.

[0045] In some embodiments, the indoor unit 400 includes a second heat exchanger 210 (i.e., a heat exchanger). The second heat exchanger 210 is configured to exchange heat between the indoor air and the refrigerant transmitted through the second heat exchanger 210. For example, in the cooling mode of the air conditioner 2000, the second heat exchanger 210 operates as an evaporator, so that the refrigerant, which has dissipated heat through the first heat exchanger 203, absorbs heat from the indoor air through the second heat exchanger 210 and evaporates. In the heating mode of the air conditioner 2000, the second heat exchanger 210 operates as a condenser, so that the refrigerant, which has absorbed heat through the first heat exchanger 203, dissipates heat to the indoor air through the second heat exchanger 210 and condenses.

[0046] In some embodiments, the second heat exchanger 210 further includes heat exchange fins to expand the contact area between the indoor air and the refrigerant transmitted in the second heat exchanger 210, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0047] As shown in Figures 1A and 1B, the indoor unit 400 further includes a second fan 3 (i.e., a blower). The second fan 3 is configured to draw indoor air into the indoor unit 400 through the indoor air inlet of the indoor unit 400 and to deliver the indoor air, after heat exchange with the second heat exchanger 210, through the air outlet 120 of the indoor unit 400. The second fan 3 provides power for the flow of indoor air.

[0048] In some embodiments, the compressor 201, the first heat exchanger 203, the expansion valve 205 and the second heat exchanger 210 connected in sequence form a refrigerant circuit, in which the refrigerant circulates and exchanges heat with the air through the first heat exchanger 203 and the second heat exchanger 210 respectively to realize the cooling mode or heating mode of the air conditioner 2000.

[0049] In some embodiments, the outdoor unit 200 further includes an expansion valve 205. The expansion valve 205 is connected between the first heat exchanger 203 and the second heat exchanger 210. The opening of the expansion valve 205 regulates the pressure of the refrigerant flowing through the first heat exchanger 203 and the second heat exchanger 210, thereby adjusting the refrigerant flow rate between the first heat exchanger 203 and the second heat exchanger 210. The flow rate and pressure of the refrigerant flowing between the first heat exchanger 203 and the second heat exchanger 210 affect the heat exchange performance of the first heat exchanger 203 and the second heat exchanger 210. The expansion valve 205 can be an electronic valve. The opening of the expansion valve 205 is adjustable to control the flow rate and pressure of the refrigerant flowing through the expansion valve 205.

[0050] In some embodiments, the outdoor unit 200 further includes a four-way valve 202. The four-way valve 202 is connected to the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner 2000 operates in cooling mode or heating mode.

[0051] Duct unit is the abbreviation of concealed air conditioner. Duct unit solves the problem of wall-mounted units and cabinet units being exposed outside and affecting the appearance. At the same time, the duct length is longer than that of ordinary household air conditioners, and the installation is more flexible. It is an emerging type of air conditioner.

[0052] Typically, a ducted air conditioner includes a heat exchanger assembly, which includes the heat exchanger and a drain pan. The heat exchanger assembly can be installed in four orientations: vertical for top airflow, horizontal for left airflow, horizontal for right airflow, and inverted for bottom airflow. To prevent condensation from splashing onto the ground, drain pans are installed at the bottom and outside of the heat exchanger to collect and drain the condensation.

[0053] However, in related technologies, condensed water generated on the surface of the heat exchanger is easily affected by the airflow within the housing, preventing it from flowing smoothly into the water pan. Furthermore, in cooling mode, if the cold air flowing from the heat exchanger assembly blows toward heat-generating components such as the electronic control assembly, condensed water can easily form within the components, affecting the reliability of the ducted air conditioner.

[0054] To address the aforementioned issues, some embodiments of the present disclosure provide a ducted air conditioner 1000. Ducted air conditioner 1000 also includes a seal and a spoiler. The seal is positioned at the first end of the heat exchanger assembly, between the heat exchanger and the electronic control assembly. This seal seals the gap at the first end of the heat exchanger assembly, preventing cold air from flowing through the gap toward heat-generating components such as the electronic control assembly.

[0055] A spoiler is located at the end of the seal and extends toward the water tray located outside the heat exchanger, abutting against it. The spoiler buffers the speed and direction of the cold air passing through the heat exchanger assembly, preventing it from directly reaching heat-generating components such as the electronic control assembly within the housing. Furthermore, the spoiler guides condensed water, allowing it to flow smoothly to the water tray located outside the heat exchanger.

[0056] In this way, not only can the cold air be prevented from blowing directly onto the heat-generating components, thus improving the reliability of the ducted air conditioner, but the condensed water can also be diverted so that the condensed water can flow into the water receiving tray.

[0057] The following describes some embodiments of a ducted air conditioner according to the present disclosure. Referring to Figures 2A and 2B , ducted air conditioner 1000 includes a housing 1. Housing 1 includes a housing cavity configured to accommodate components such as a heat exchanger, a fan, and an electronic control assembly. Housing 1 protects the components within the cavity.

[0058] In some embodiments, the housing 1 further includes an air inlet 110 . In FIG. 2A , the air inlet 110 may be located at the bottom of the housing 1 , and air flow may enter the housing 1 through the air inlet 110 for heat exchange.

[0059] In some embodiments, the housing 1 further includes an air outlet 120 . In FIG. 2B , the air outlet 120 may be located at the top of the housing 1 , and the airflow after heat exchange may flow out through the air outlet 120 .

[0060] In some embodiments, the air inlet 110 and the air outlet 120 are disposed opposite each other. For example, the air inlet 110 is disposed at the top of the housing 1, and the air outlet 120 is disposed at the bottom of the housing 1. Alternatively, the air inlet 110 is disposed at the bottom of the housing 1, and the air outlet 120 is disposed at the top of the housing 1.

[0061] 2A , the duct unit 1000 further includes a heat exchanger assembly 2 disposed within the housing 1. The heat exchanger assembly 2 is configured to exchange heat with the airflow entering the housing 1 to heat or cool the airflow.

[0062] In some embodiments, referring to Figures 2A and 2B , the ducted air conditioner 1000 further includes a fan 3. The fan 3 is disposed within the housing 1. For example, the fan 3 is spaced apart from the heat exchanger assembly 2 in the height direction of the housing 1 (the vertical direction as shown in Figure 2A ), and the fan 3 is disposed above the heat exchanger assembly 2. The fan 3 is configured to drive air flow, so that the airflow enters the housing 1 through the air inlet 110 to exchange heat with the heat exchanger 100, and the airflow after heat exchange is discharged through the air outlet 120.

[0063] In some embodiments, referring to FIG. 2B , the duct air conditioner 1000 further includes an electronic control assembly 4 . The electronic control assembly 4 is disposed within the housing 1 . The electronic control assembly 4 is configured to couple to an external power supply to supply power to the electrical components of the duct air conditioner 1000 (e.g., the fan 3 ). The electronic control assembly 4 is also configured to control the operating status of the electrical components of the duct air conditioner 1000 .

[0064] The heat exchanger assembly 2 in some embodiments of the present disclosure is described below.

[0065] In some embodiments, the heat exchanger assembly 2 includes a heat exchanger 100 , which is configured to exchange heat with an airflow flowing therethrough to form a heat exchanged airflow.

[0066] In some embodiments, the heat exchanger 100 includes at least two heat exchange sections. Referring to FIG3 , the at least two heat exchange sections include a first heat exchange section 101 and a second heat exchange section 102. The first end of the first heat exchange section 101 is connected to the first end of the second heat exchange section 102, and the second end of the first heat exchange section 101 and the second end of the second heat exchange section 102 are spaced apart from each other.

[0067] In some embodiments of the present disclosure, the heat exchanger assembly 2 can be installed in four directions, namely, vertical with upper air outlet (as shown in Figure 3), horizontal with left air outlet, horizontal with right air outlet (as shown in Figure 4), or inverted with lower air outlet.

[0068] In some embodiments, referring to Figures 3 and 4 , the heat exchanger assembly 2 further includes a first water receiving tray 51 (a primary water receiving tray), which is disposed at the second end (i.e., the bottom end as shown in Figure 3 ) of the heat exchanger 100. When the heat exchanger assembly 2 is installed in a vertical configuration with upward airflow or an inverted configuration with downward airflow (i.e., when the heat exchanger assembly 2 is in an upright position), the first water receiving tray 51 receives condensed water.

[0069] In some embodiments, the heat exchanger assembly 2 further includes a second water receiving pan 52 (secondary water receiving pan), which is disposed on one side of the heat exchanger 100 in the width direction (the left-right direction as shown in FIG3 ), and one end of the second water receiving pan 52 is connected to the first water receiving pan 51. When the heat exchanger assembly 2 is installed horizontally with left or right air outlet (i.e., when the heat exchanger assembly 2 is in a horizontal position), the second water receiving pan 52 collects condensed water.

[0070] 3 and 4 , the heat exchanger assembly 2 further includes a seal 60 connected to a first end (i.e., the top end as shown in FIG3 ) of the heat exchanger 100. The seal 60 is configured to seal the gap between the first heat exchange portion 101 and the second heat exchange portion 102.

[0071] In some embodiments, the sealing member 60 includes at least two sealing portions 61 , and the number of the sealing portions 61 may correspond to the number of the heat exchange portions.

[0072] In some embodiments, the sealing portion 61 includes a first sealing plate 611 , and the first sealing plate 611 is disposed at a first end (eg, a top end) of the first heat exchange portion 101 .

[0073] In some embodiments, the sealing portion 61 further includes a second sealing plate 612 , which is connected to the first sealing plate 611 . The second sealing plate 612 is disposed at a first end (eg, a top end) of the second heat exchange portion 102 .

[0074] In some embodiments, the shapes of the first sealing plate 611 and the second sealing plate 612 match the shape of the top surface of the heat exchanger 100. The angle between the first sealing plate 611 and the second sealing plate 612 is denoted as a first angle, and the angle between the top surface of the first heat exchange portion 101 and the top surface of the second heat exchange portion 102 is denoted as a second angle. The first angle is equal to the second angle.

[0075] 3 , the second angle between the top surface of the first heat exchange portion 101 and the top surface of the second heat exchange portion 102 is an obtuse angle, and the first angle is equal to the second angle, and the first angle is also an obtuse angle.

[0076] In this way, the first sealing plate 611 and the second sealing plate 612 can respectively and tightly cover the top surface of the heat exchanger 100 to reduce the gap between the sealing member 60 and the top surface of the heat exchanger 100, thereby improving the sealing effect.

[0077] In some embodiments, the first sealing plate 611 and the second sealing plate 612 may be an integral piece, which is beneficial for improving the sealing effect of the gap between the first heat exchange portion 101 and the second heat exchange portion 102 and improving assembly efficiency.

[0078] Of course, in some embodiments, the first sealing plate 611 and the second sealing plate 612 may be separate parts, which facilitates disassembly.

[0079] In some embodiments of the present disclosure, a seal 60 is provided at the first end of the heat exchanger 100 to block the airflow from flowing through the gap at the top of the first heat exchange part 101 and the second heat exchange part 102, thereby preventing condensed water on the surface of the heat exchanger 100 from being blown by the airflow to electrical components such as the electric control component 4 inside the shell 1, thereby improving the reliability of the duct machine 1000.

[0080] 5 , the sealing member 60 further includes a connecting portion 62 . The connecting portion 62 is disposed at an end of the sealing portion 61 .

[0081] In some embodiments, referring to FIG6 , the connecting portion 62 includes a first connecting plate 621, which is disposed at the first end (the rear end as shown in FIG5 ) of the first sealing plate 611 and the second sealing plate 612. A first side of the first connecting plate 621 is connected to the first end of the first sealing plate 611, and a second side of the first connecting plate 621 is connected to the first end of the second sealing plate 612.

[0082] In some embodiments, referring to FIG6 , the connecting portion 62 further includes a second connecting plate 622, which is disposed at the second ends (front ends as shown in FIG5 ) of the first sealing plate 611 and the second sealing plate 612. A first side of the second connecting plate 622 is connected to the second end of the first sealing plate 611, and a second side of the second connecting plate 622 is connected to the second end of the second sealing plate 612.

[0083] It can be understood that the setting of the first connecting plate 621 and the second connecting plate 622 can, on the one hand, further improve the sealing effect of the seal 60, and on the other hand, can also improve the structural stability of the first sealing plate 611 and the second sealing plate 612, thereby avoiding deformation of the first sealing plate 611 and the second sealing plate 612.

[0084] In some embodiments, the first connecting plate 621 and the second connecting plate 622 are each an isosceles triangle. The first ends of the first sealing plate 611 and the second sealing plate 612 are respectively connected to the two waists of the first connecting plate 621, and the second ends of the first sealing plate 611 and the second sealing plate 612 are respectively connected to the two waists of the second connecting plate 621. In other words, the first side and the second side are respectively the two waists of the isosceles triangle.

[0085] It can be understood that the included angle between the first sealing plate 611 and the second sealing plate 612 is the included angle between the two legs of an isosceles triangle.

[0086] 3 and 6 , in some embodiments, the seal 60 further includes at least one extension 63 (connection piece), the extension 631 being disposed on at least one of the first connection plate 621 or the second connection plate 622 at a position close to the heat exchanger 100. The seal 60 is connected to the heat exchanger 100 via the extension 63.

[0087] Taking the first connecting plate 621 as an example, two extensions 63 are provided on the first connecting plate 621 near the heat exchanger. The two extensions 63 can be provided on the first and second sides of the first connecting plate 621, respectively. One of the two extensions 63 extends toward the first heat exchange portion 101 to be disposed opposite the first heat exchange portion 101, and the other of the two extensions 63 extends toward the second heat exchange portion 102 to be disposed opposite the second heat exchange portion 102.

[0088] In some embodiments, the extension portion 63 includes a connection hole into which a screw connected to the heat exchanger 100 is connected. The connection portion 62 is fixedly connected to the heat exchanger 100 through the screw hole of the extension portion 63, thereby achieving a fixed connection between the sealing member 60 and the top of the heat exchanger 100.

[0089] In some embodiments, referring to Figures 3, 5 and 6, the seal 60 also includes a reinforcement member 65 (reinforced flange), which is arranged on the side away from each other of at least one of the first sealing plate 621 and the second sealing plate 622, and the reinforcement member 65 extends toward the side close to the heat exchanger 100.

[0090] In some embodiments, the angle between the sealing portion 61 and the reinforcing member 65 is an obtuse angle. In this way, the reinforcing member 65 is spaced apart from the heater 100, which facilitates the installation of the sealing member 60.

[0091] It is understood that the provision of the reinforcement 65 can improve the structural stability of the seal 60 and extend the service life of the seal 60. Furthermore, referring to Figures 4 and 6 , when the heat exchanger assembly 2 is installed horizontally with left and right air outlets, the reinforcement 65 can also guide the condensed water on the surface of the upper heat exchanger 100 so that the condensed water can drip smoothly into the second water receiving tray 52.

[0092] In some embodiments, the sealing member 60 is an integral member, which is beneficial for improving the sealing effect of the sealing member 60 and improving assembly efficiency.

[0093] Of course, in some embodiments, the sealing member 60 may also be a split member, which is easy to disassemble and replace.

[0094] 3 and 7 , the heat exchanger assembly 2 further includes at least one spoiler 70, which is connected to the seal 60 and configured to disrupt the heat exchange airflow after heat exchange through the heat exchanger 100. For example, the spoiler 70 is disposed at an end of the seal 60 in the longitudinal direction (the front-to-back direction as shown in FIG. 5 ), and the spoiler 70 extends toward the second water receiving tray 52 to abut against the second water receiving tray 52.

[0095] In some embodiments, referring to Figures 5 and 6, the sealing member 60 further includes a fitting portion 64, which is perpendicularly disposed to a third side (the side opposite the angle between the two waists) of the connecting portion 62. The spoiler 70 is connected to the sealing member 60 via the fitting portion 64. This improves the stability of the connection between the spoiler 70 and the sealing member 60.

[0096] For example, the connection between the fitting portion 64 and the spoiler 70 may be screw connection.

[0097] In some embodiments, the at least one spoiler 70 includes two spoilers 70 , and the two spoilers 70 are symmetrically disposed at both ends of the sealing member 60 in the length direction.

[0098] In some embodiments, the fitting portion 64 includes a first fitting plate 641 , which is disposed on a third side of the first connecting plate 621 . One of the two spoilers 70 may be connected to the first connecting plate 621 via the first fitting plate 641 .

[0099] In some embodiments, the fitting portion 64 includes a second fitting plate 642 , which is disposed on a third side of the second connecting plate 622 . The other of the two spoilers 70 may be connected to the second connecting plate 622 via the second fitting plate 642 .

[0100] On the one hand, the provision of the spoiler 70 can buffer the wind speed of the cold air passing through the heat exchanger 100 and interfere with the wind direction of the cold air, thereby preventing the cold air from blowing towards heat-generating components such as the electronic control component 4.

[0101] For example, referring to Figure 4 , if the heat exchanger assembly 2 is installed horizontally with air outlet from the right, the two spoilers 70 are located on the left side of the electronic control assembly 4. As the cool air from the heat exchanger assembly 2 blows from left to right, the spoilers 70 can buffer the wind speed of the cool air as it passes through the two spoilers 70, slowing it down. Furthermore, the spoilers 70 can also disrupt the direction of the cool air, thereby dispersing it.

[0102] In this way, the cold air is prevented from being concentratedly blown toward the electronic control component 4, and the generation of condensed water on the electronic control component 4 is reduced, thereby protecting the electronic control component 4 and improving the reliability of the duct air conditioner 1000.

[0103] On the other hand, the provision of the spoiler 70 can also guide the condensed water so that the condensed water can flow smoothly to the second water receiving tray 52 .

[0104] For example, referring to Figure 4, the condensed water of the heat exchanger 100 flows from left to right driven by the air flow until it reaches the position of the spoiler 70. At this time, part of the condensed water can flow downward along the two spoilers 70 to the second water receiving tray 52, and the other part of the condensed water can drip into the second water receiving tray 52 along the reinforcement 65.

[0105] In some embodiments, the spoiler 70 includes a first spoiler 71 (main spoiler), one end of the first spoiler 71 is connected to the second water receiving tray 52, and the other end of the first spoiler 71 is connected to the sealing member 60. For example, the first spoiler 71 can be fixedly connected to the second water receiving tray 52 by screws.

[0106] In some embodiments, referring to FIG. 5 , the width L of the first spoiler 71 may be any value between [50 mm and 80 mm].

[0107] For example, the width L of the first spoiler 71 is 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, etc.

[0108] It is understood that if the width L of the first spoiler 71 is less than 50 mm, the spoiler 71 will weaken the cooling air flow, thereby reducing the reliability of the electronic control assembly 4. If the width L of the first spoiler 71 is greater than 80 mm, it will hinder the flow of air within the housing 1, thereby reducing the air outlet effect of the duct air conditioner 1000.

[0109] Thus, by limiting the width L of the first spoiler 71 to a predetermined range, the cold air heated by the heat exchanger 100 can be disrupted and buffered while ensuring the air outlet quality of the duct air conditioner 1000, thereby preventing the cold air from blowing directly toward the electronic control component 4. Furthermore, the first spoiler 71 can also provide a diversion space for condensed water, thereby guiding the condensed water.

[0110] In some embodiments, referring to Figure 5, the spoiler 70 also includes a second spoiler 72 (auxiliary spoiler), which is vertically arranged on both sides of the first spoiler 71. The second spoiler 72 extends from one end of the first spoiler 71 to the other end, and the length of the second spoiler 72 is ≤ the distance between the seal 60 and the second water receiving tray 52.

[0111] It is understandable that setting the length T of the second spoiler 72 to be less than or equal to the distance between the seal 60 and the second water receiving tray 52 facilitates installation of the spoiler 70 and can avoid the pipes on the heat exchanger 100 .

[0112] In some embodiments, referring to FIG. 7 , the width M of the second spoiler 72 may be any value between [50 mm and 80 mm].

[0113] For example, the width M of the second spoiler 72 is 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, etc.

[0114] In other embodiments, the width M of the second spoiler 72 may also be any value between [45 mm, 60 mm].

[0115] It is understood that if the width M of the second spoiler 72 is less than 45 mm, the spoiler 72 will weaken the cold air flow, thereby reducing the reliability of the electronic control component 4. If the width L of the second spoiler 72 is greater than 80 mm, it will hinder the flow of air in the housing 1, thereby reducing the air outlet effect of the duct air conditioner 1000.

[0116] Thus, by setting the width M of the second spoiler 72 within a predetermined range, the cold air heated by the heat exchanger 100 can be disrupted and buffered, while ensuring the air outlet quality of the duct air conditioner 1000, thereby preventing the cold air from blowing directly toward the electronic control component 4. Furthermore, the second spoiler 72 can also provide a diversion space for condensed water, thereby guiding the condensed water.

[0117] 5 , the spoiler 70 further includes a third spoiler 73 (secondary spoiler), which is disposed outside the first spoiler 71. The third spoiler 73 extends from the other end of the first spoiler 71 toward the second spoiler 72 and is connected to the second spoiler 72.

[0118] In some embodiments, the third spoiler 73 forms a second preset angle with the first spoiler 71. For example, the second preset angle is 90 degrees. In this case, the third spoiler 73 is perpendicular to the outside of the first spoiler 71.

[0119] In some embodiments, the second spoiler 72 and the third spoiler 73 are located in the same plane, that is, the second preset angle is equal to the second preset angle.

[0120] The function of the third spoiler 73 is similar to that of the second spoiler 72 . By cooperating with the first spoiler 71 , a guide space is formed for the condensed water, and the cold air in the heat exchanger 100 can be buffered and the turbulence can be dispersed.

[0121] 7 , a width N of the third spoiler 73 is smaller than a width M of the second spoiler 72 . This allows for the piping on the heat exchanger 100 to be avoided, thereby facilitating installation of the spoiler 70 .

[0122] In some embodiments, the spoiler 70 is an integrated piece, which is convenient for installation and helps to improve assembly efficiency. It also helps to improve the sealing performance of the spoiler 70, thereby improving the ability of the spoiler 70 to interfere with the airflow.

[0123] Of course, in some embodiments, the spoiler 70 may also be a split piece, which is convenient for disassembly.

[0124] In some embodiments, the heat exchanger 100 includes a heat exchange system including a heat exchange circuit.

[0125] For example, either the first heat exchange unit 101 or the second heat exchange unit 102 includes n heat exchange circuits, and the inlets of the n heat exchange circuits are located below the outlets, where n ≥ 2. That is, the refrigerant in the heat exchange circuits flows in a bottom-in, top-out manner. This facilitates adjustment of the refrigerant flow rate, thereby improving the refrigerant diversion effect.

[0126] In some embodiments, x of the n heat exchange circuits are located below the remaining nx heat exchange circuits, where x ≥ 1. That is, the n heat exchange circuits are divided into upper and lower sections. This reduces pressure loss in the heat exchanger, thereby improving refrigerant heat exchange efficiency. For example, if x = 1, one of the n heat exchange circuits is located below the remaining n-1 heat exchange circuits.

[0127] In some embodiments, the inlets and outlets of m of the n heat exchange circuits are located on corresponding sides of the corresponding heat exchange portion, where m ≥ n-1. For example, the inlets and outlets of the m heat exchange circuits are located on the inner and outer sides of the corresponding heat exchange portion, respectively, in the width direction. Thus, the refrigerant inlet and outlet are located on corresponding sides of the heat exchanger 100.

[0128] Some embodiments of the present disclosure further provide a refrigerant distribution device, which is in communication with the n heat exchange circuits and configured to distribute refrigerant to the n heat exchange circuits.

[0129] In some embodiments, the heat exchange system further includes a refrigerant distribution device. Referring to FIG. 8 and FIG. 13 , the refrigerant distribution device includes a main inlet pipe 10 , through which the refrigerant throttled by the expansion valve 205 flows into the heat exchange circuit.

[0130] In some embodiments, the refrigerant distribution device further includes 2n branch inlet pipes 11, and the main inlet pipe 10 is connected to the 2n branch inlet pipes 11. Of the 2n branch inlet pipes 11, n branch inlet pipes 11 are respectively connected to the inlets of the n heat exchange circuits of the first heat exchange section 101, and the other n branch inlet pipes 11 are respectively connected to the inlets of the n heat exchange circuits of the second heat exchange section 102.

[0131] In some embodiments, referring to FIG. 8 and FIG. 14 , the refrigerant distribution device further includes a main outlet pipe 20 , and the refrigerant after heat exchange with the airflow in the heat exchanger 100 is communicated through the main outlet pipe 20 .

[0132] In some embodiments, the refrigerant distribution device further includes 2n branch pipes 21, and the main outlet pipe 20 is connected to the 2n branch pipes 21. Of the 2n branch pipes 21, n branch pipes 21 correspond to outlets of n heat exchange circuits on one heat exchanger 100, and the other n branch pipes 21 correspond to outlets of n heat exchange circuits on another heat exchanger 100.

[0133] For example, the refrigerant distribution process includes: the refrigerant enters the main inlet pipe 10 and is divided into 2n branch inlet pipes 11. The refrigerant in n of the 2n branch inlet pipes 11 flows into the n heat exchange circuits of the first heat exchange section 101, and the refrigerant in the other n branch inlet pipes 11 flows into the n heat exchange circuits of the second heat exchange section 102.

[0134] Afterwards, the refrigerant in the n heat exchange circuits of the first heat exchange section 101 flows out from n branch pipes 21 respectively, and the refrigerant in the n heat exchange circuits of the second heat exchange section 102 flows out from another n branch pipes 21 respectively. Finally, the refrigerant in the 2n branch pipes 21 converges into the main outlet pipe 20 and flows out through the main outlet pipe 20. This completes the flow of refrigerant in the heat exchanger 100.

[0135] In summary, in some embodiments of the present disclosure, the n heat exchange circuits of any heat exchange unit are divided into two parts, an upper part and an lower part. This can reduce the pressure loss of the heat exchanger and facilitate the adjustment of refrigerants with different flow rates.

[0136] Furthermore, the inlets of the n heat exchange circuits are all located below their outlets, and the inlets and outlets of m of the n heat exchange circuits are located on opposite sides of the corresponding heat exchange section in the width direction, with m ≥ n-1. In other words, the refrigerant flows in from the bottom and out from the top, with the refrigerant inlet and outlet located on the inside and outside of the corresponding heat exchange section, respectively. This improves refrigerant flow diversion and thus enhances refrigerant heat exchange efficiency.

[0137] In addition, since heat exchange pipelines are respectively provided on the inside, outside and middle of the heat exchanger 100 under the above-mentioned heat exchange circuit setting method, and the refrigerant flow in each heat exchange circuit is roughly the same, the heat exchanger 100 can adapt to different installation directions. Regardless of how the wind direction changes, a uniform heat exchange effect can be achieved, thereby improving the reliability of the heat exchange system.

[0138] It should be noted that the inner side of the heat exchanger 100 refers to the two opposing sides of the first heat exchange section 101 and the second heat exchange section 102, and the other side of the first heat exchange section 101 and the second heat exchange section 102 corresponding to the inner side is the outer side. The predetermined area of ​​the heat exchanger 100 refers to the area between one-quarter and one-half of the length of the heat exchanger 100 from bottom to top, i.e., the lower center of the heat exchanger 100.

[0139] The following describes the configuration of the heat exchange circuit using n = 4, x = 1, and m = 3. Of course, in other embodiments, n can also be 2, 3, 5, 6, 7, ..., and m can also be 1, 2, 3, 5, 6, ....

[0140] In some embodiments, any one of the first heat exchange portion 101 and the second heat exchange portion 102 includes four heat exchange circuits, and the inlets and outlets of three of the four heat exchange circuits are respectively located inside and outside the corresponding heat exchange portion.

[0141] In some embodiments, the heat exchange circuit includes a first sub-heat exchange circuit. The first sub-heat exchange circuit is entirely located on a side of the corresponding heat exchange portion close to the second end.

[0142] In some embodiments, the first heat exchange sub-loop includes a first inlet 31 , which is located at the second end of the heat exchanger 100 and close to the inner side of the heat exchanger 100 .

[0143] In some embodiments, the first heat exchange sub-loop further includes a first outlet 32 ​​. The first outlet 32 ​​is located in a predetermined area of ​​the heat exchanger 100 and is disposed close to the outside of the heat exchanger 100 .

[0144] For example, the first inlet 31 is located on the inner side of the bottom end of the heat exchanger 100 , and the first outlet 32 ​​is located on the outer side of the upper middle portion of the heat exchanger 100 .

[0145] In some embodiments, the heat exchange circuit further includes a second sub-heat exchange circuit. The second sub-heat exchange circuit is entirely located on a side of the heat exchange portion close to the first end.

[0146] In some embodiments, the second heat exchange sub-loop includes a second inlet 33 , which is located in a predetermined area of ​​the heat exchanger 100 and close to the outside of the heat exchanger 100 .

[0147] In some embodiments, the second heat exchange sub-loop further includes a second outlet 34 . The second outlet 34 is located at the top of the heat exchanger 100 and is disposed close to the inner side of the heat exchanger 100 .

[0148] For example, the second inlet 33 is located outside the heat exchanger 100 , and the second outlet 34 is located inside the heat exchanger 100 .

[0149] In some embodiments, the heat exchange circuit further includes a third sub-heat exchange circuit. The third sub-heat exchange circuit is entirely located on a side of the heat exchange portion close to the first end.

[0150] In some embodiments, the third heat exchange sub-loop includes a third inlet 35 , which is located in the middle and lower part of the heat exchanger 100 and close to the inner side of the heat exchanger 100 .

[0151] In some embodiments, the third heat exchange sub-loop further includes a third outlet 36 , which is located at the top of the heat exchanger 100 and close to the outside of the heat exchanger 100 .

[0152] For example, the third inlet 35 is located on the inner side of the heat exchanger 100 , and the third outlet 36 is located on the outer side of the heat exchanger 100 ;

[0153] In some embodiments, the heat exchange circuit further includes a fourth sub-heat exchange circuit. The fourth sub-heat exchange circuit is entirely located on a side of the heat exchange portion close to the first end.

[0154] In some embodiments, the fourth heat exchange sub-loop includes a fourth inlet 37 , which is located in the middle and lower part of the heat exchanger 100 and between the second inlet 33 and the third inlet 35 .

[0155] In some embodiments, the fourth heat exchange sub-loop further includes a fourth outlet 38 . The fourth outlet 38 is located at the top end of the heat exchanger 100 and between the second outlet 34 and the third outlet 36 .

[0156] In some embodiments, any one of the four heat exchange circuits further includes a loop pipe 300, which is folded multiple times to form multiple straight segments and multiple bent segments. The multiple straight segments are arranged in parallel along the length direction of the heat exchanger 100 (the front-to-back direction as shown in Figure 3), and the multiple bent segments are distributed on the two end faces of the heat exchanger 100 and connect the corresponding ends of two adjacent straight segments among the multiple straight segments.

[0157] In this way, on the one hand, the space occupied by the loop pipe 300 can be reduced, so that within the same occupied space, the loop pipe 300 can be extended as much as possible, thereby increasing the length of the refrigerant flow path and the heat exchange area. On the other hand, the setting of multiple bending sections can also play a buffering role for the refrigerant, extending the residence time of the refrigerant in the loop pipe 300, thereby improving the heat exchange effect of the refrigerant in the heat exchange circuit.

[0158] In some embodiments, the first sub-circuit heat exchange loop further includes a first sub-circuit pipe 301 , a first end of the first sub-circuit pipe 301 is connected to the first inlet 31 , and a second end of the first sub-circuit pipe 301 is connected to the first outlet 32 ​​.

[0159] In some embodiments, referring to Figures 9 to 11, the first sub-loop pipe 301 includes 24 straight line segments, 8 of the 24 straight line segments are located on the inner side of the heat exchanger 100, another 8 straight line segments are located in the middle of the heat exchanger 100, and the remaining 8 straight line segments are located on the outer side of the heat exchanger 100.

[0160] For example, the refrigerant flow path of the first sub-heat exchange circuit includes: the refrigerant in the branch inlet pipe 11 enters the first sub-circuit pipe 301 through the first inlet 31, the refrigerant flows through multiple straight segments and multiple bending segments of the first sub-circuit pipe 301, and then flows from the first outlet 32 ​​to the branch pipe 21.

[0161] In this way, the refrigerant in the first sub-heat exchange circuit flows from bottom to top along the heat exchanger 100, and flows evenly through the outside, center and inside of the heat exchanger 100, thereby helping to reduce the pressure loss of the heat exchanger and improve the heat exchange effect of the heat exchanger.

[0162] In some embodiments, the second sub-circuit heat exchange loop further includes a second sub-circuit pipe 302 , a first end of the second sub-circuit pipe 302 is connected to the second inlet 33 , and a second end of the second sub-circuit pipe 302 is connected to the second outlet 34 .

[0163] In some embodiments, referring to FIG. 9 to FIG. 11 , the second sub-loop pipe 302 includes 18 straight line segments, 8 of which are located outside the heat exchanger 100 , and the remaining 10 are located inside the heat exchanger 100 .

[0164] For example, the refrigerant flow path of the second sub-heat exchange circuit includes: the refrigerant in the branch inlet pipe 11 enters the second sub-circuit pipe 302 through the second inlet 33, the refrigerant flows through multiple straight segments and multiple bending segments of the second sub-circuit pipe 302, and then flows from the second outlet 34 to the branch pipe 21.

[0165] In this way, the refrigerant in the second sub-heat exchange circuit flows from bottom to top along the heat exchanger 100 , may first flow through the outside of the heat exchanger 100 , then flow through the inside of the heat exchanger 100 , and finally flow out from the top inside the heat exchanger 100 .

[0166] In some embodiments, the third sub-circuit heat exchange loop further includes a third sub-circuit pipe 303 , a first end of the third sub-circuit pipe 303 is connected to the third inlet 35 , and a second end of the third sub-circuit pipe 303 is connected to the third outlet 36 .

[0167] 10 and 11 , the third sub-loop pipe 303 includes 18 straight line segments, 8 of which are located inside the heat exchanger 100 , and the remaining 10 are located outside the heat exchanger 100 .

[0168] For example, the refrigerant flow path of the third sub-heat exchange circuit includes: the refrigerant in the branch inlet pipe 11 enters the third sub-circuit pipe 303 through the third inlet 35, the refrigerant flows through multiple straight sections and multiple bending sections of the third sub-circuit pipe 303, and then flows from the third outlet 36 to the branch pipe 21.

[0169] In this way, the refrigerant in the third sub-heat exchange circuit flows from bottom to top along the heat exchanger 100 , may first flow through the inside of the heat exchanger 100 , then flow through the outside of the heat exchanger 100 , and finally flow out from the top outside of the heat exchanger 100 .

[0170] In some embodiments, the fourth sub-circuit heat exchange loop further includes a fourth sub-circuit pipe 304 , a first end of the fourth sub-circuit pipe 304 is connected to the fourth inlet 37 , and a second end of the fourth sub-circuit pipe 304 is connected to the fourth outlet 38 .

[0171] In some embodiments, referring to FIG. 9 to FIG. 11 , the straight section of the fourth sub-loop pipe 304 is located at the center of the heat exchanger 100 .

[0172] For example, the refrigerant flow path of the fourth sub-heat exchange circuit includes: the refrigerant in the branch inlet pipe 11 enters the fourth sub-circuit pipe 304 through the fourth inlet 37, the refrigerant flows through multiple straight segments and multiple bending segments of the fourth sub-circuit pipe 304, and then flows from the fourth outlet 38 to the branch pipe 21.

[0173] In this way, the refrigerant in the fourth sub-circuit flows from bottom to top along the fourth sub-circuit pipe 304 and flows through the center of the heat exchanger 100 .

[0174] In summary, the coordination of the first, second, third, and fourth sub-heat exchange circuits can reduce the pressure loss of the heat exchanger, improve the refrigerant diversion effect, adjust the refrigerant flow rates, and enhance the refrigerant heat exchange efficiency. Furthermore, the heat exchanger 100 can adapt to changes in wind direction according to different installation orientations, improving the heat exchange effect between the inside and outside of the heat exchanger 100, thereby achieving uniform heat exchange for airflows flowing in different directions.

[0175] In some embodiments, referring to FIG12 , the refrigerant distribution device further includes a distributor 12 disposed at a first end (e.g., a top end) of the main inlet pipe 10. The 2n branch inlet pipes are connected to the main inlet pipe 10 via the distributor 12. One end of the distributor 12 is connected to the main inlet pipe 10, and the other end of the distributor 12 is connected to the 2n branch inlet pipes.

[0176] In some embodiments, the refrigerant distribution device further includes a buffer tube 40 , which is disposed at the second end of the main inlet pipe 10 . That is, the buffer tube 40 and the distributor 12 are connected via the main inlet pipe 10 .

[0177] In some embodiments, the first end of the buffer tube 40 is a closed end, and the second end of the buffer tube 40 is an open end, and the second end of the buffer tube 40 is connected to the main inlet pipe 10 and further connected to the distributor 12 through the main inlet pipe 10 .

[0178] In some embodiments, referring to Figures 8, 13, and 18, the buffer tube 40 includes an opening 41 disposed on one side of the buffer tube body near the closed end. After entering the buffer tube 40 through opening 41, the refrigerant enters the main inlet pipe 10 from the buffer tube 40, and continues into the distributor 12. The refrigerant then enters the first heat exchange section 101 and the second heat exchange section 102 through the 2n branch inlet pipes 11 connected to the distributor 12.

[0179] It can be understood that one end of the buffer tube 40 is a closed end, which can play a buffering role on the refrigerant flowing into the buffer tube 40 from the opening 41, increase the uniformity of the refrigerant flow, make the refrigerant flow rate basically consistent, improve the refrigerant heat exchange effect, and reduce the refrigerant flow sound.

[0180] In some embodiments, the buffer tube 40 further includes a connecting tube 42 (elbow), and the opening 41 is connected to the expansion valve 205 through the connecting tube 42 .

[0181] It can be understood that the expansion valve 205 can throttle the refrigerant, and the throttled refrigerant enters the connecting pipe 42. The connecting pipe 42 can buffer the flow of the refrigerant. When the refrigerant flows through the connecting pipe 42, centrifugal force will be generated due to the turning, which can make the liquid refrigerant and the gaseous refrigerant fully mixed, making the refrigerant flow rate uniform and reducing the noise of the refrigerant flow.

[0182] In some embodiments, referring to FIG. 15 and FIG. 19 , the refrigerant distribution device further includes a filter 44 , which is disposed inside the buffer tube 40 .

[0183] The filter screen 44 can be made of stainless steel, and the filter screen 44 can be integrally formed into a hollow cylindrical shape with one end open through a processing technique.

[0184] In some embodiments, the refrigerant distribution device also includes a fixing ring 46, and the open end of the filter screen 44 is connected to the fixing ring 46. A support frame extending into the interior of the filter screen 44 is fixed on the fixing ring 46. The support frame is configured to support the filter screen 44, so that the filter screen 44 can maintain a cylindrical shape, thereby ensuring that the filter screen 44 can play a filtering role.

[0185] In some embodiments, referring to FIG. 16 , the support frame includes a support ring 47 .

[0186] In some embodiments, the support frame further includes at least two support rods 48, and at least two symmetrical support rods 48 are fixed to a support ring 47. The ends of the support rods 48 are fixed to the fixing ring 46, and the fixing method can be welding.

[0187] In some embodiments, the support ring 47 is in a circular ring shape, the outer diameter of the support ring 47 is equal to the inner diameter of the filter screen 44, the support ring 47 is supported on the end of the filter screen 44, and the support rod 48 is in contact with the inner wall of the filter screen 44, thereby supporting the filter screen 44 so that the filter screen 44 can maintain a cylindrical shape.

[0188] In some embodiments, filter 44 is a hollow cylinder with an open end. Filter 44 fits within buffer tube 40. Refrigerant flowing into buffer tube 40 through opening 41 is filtered by filter 44 before flowing through diverter ring 45. Filter 44 filters the refrigerant within buffer tube 40, preventing impurities in the refrigerant from clogging the pipe. Furthermore, filter 44 buffers and mixes the refrigerant, maintaining a substantially consistent flow rate and ensuring thorough mixing, thereby reducing noise associated with the refrigerant flow.

[0189] In some embodiments, referring to FIG. 17A , FIG. 17B , and FIG. 19 , the refrigerant distribution device further includes a diverter ring 45 , which is disposed inside the buffer tube 40 .

[0190] The diverter ring 45 is annular and is fixed to the fixing ring 46 by welding.

[0191] The outer diameter of the diverter ring 45 is equal to the inner diameter of the buffer tube 40. The outer wall of the diverter ring 45 fits closely to the inner wall of the buffer tube 40, and the inner diameter of the diverter ring 45 is equal to or greater than half the inner diameter of the buffer tube 40. The provision of the diverter ring 45 can, on the one hand, reduce the diameter of the refrigerant flowing through the diverter ring 45, thereby buffering and mixing the refrigerant and ensuring uniform mixing. On the other hand, it can disperse small bubbles in the refrigerant to avoid refrigerant flow noise.
