[0002] In the field of air conditioning technology, environmental information is generally obtained by setting a temperature sensor at the air inlet of the air conditioner. Although this method can obtain ambient temperature information, it cannot fully reflect the actual operation of the air conditioner, resulting in low control accuracy of the air conditioner for environmental indicators such as temperature. Utility Model Content

[0003] The technical problem this invention aims to solve is that in existing technologies, environmental information is obtained by setting a temperature sensor at the air inlet of the air conditioner. While this method can acquire ambient temperature information, it cannot fully reflect the actual operating conditions of the air conditioner, resulting in low accuracy in controlling environmental indicators such as temperature. This invention provides an evaporator and a cabinet-type air conditioner.

[0004] This utility model aims to provide a cabinet-type air conditioner, including:

[0005] The outer casing has an upper air vent at its upper part and a lower air vent at its lower part, and an air duct is provided inside the outer casing.

[0006] A fan is located inside the housing, and under the action of the fan, the airflow between the upper air inlet and the lower air inlet flows through the air duct;

[0007] A heat exchanger is located inside the air duct. The heat exchanger has a first side communicating with the upper air outlet and a second side communicating with the lower air outlet. Airflow flowing through the air duct flows through the heat exchanger in the direction from the first side to the second side or in the direction from the second side to the first side.

[0008] A first sensor group and a second sensor group are located on a first side and a second side of the heat exchanger, respectively. The first sensor group is used to detect a first airflow parameter on the first side of the heat exchanger, and the second sensor group is used to detect a second airflow parameter on the second side of the heat exchanger.

A second connecting groove is formed on the second shelf, and a second water receiving groove communicating with the first water receiving groove is provided inside the second connecting groove.

[0022] In the first air outlet mode, the fan operates, and the airflow entering from the downwind vent enters the heat exchanger from the first side of the heat exchanger as it flows through the air duct, and flows out from the second side of the heat exchanger, and is finally discharged into the room from the upwind vent.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In the field of air conditioning technology, environmental information is generally obtained by setting a temperature sensor at the air inlet of the air conditioner. Although this method can obtain ambient temperature information, it cannot fully reflect the actual operation of the air conditioner, resulting in low control accuracy of the air conditioner for environmental indicators such as temperature.

[0041] Based on this, the following embodiments are proposed.

[0042] Example 1:

[0043] like Figure 1 As shown, this embodiment provides a heat exchanger, including: a housing 7, a fan 704, a heat exchanger, a first sensor group 2, and a second sensor group 3. The housing 7 has an upper air inlet 701 at its upper part and a lower air inlet 702 at its lower part. An air duct 703 is also provided inside the housing 7, connecting to the upper air inlet 701 and the lower air inlet 702 respectively. Airflow can enter or exit the cabinet air conditioner through the upper air inlet 701, the lower air inlet 702, and the air duct 703. The fan 704 is located inside the housing 7. When the fan 704 is started, airflow enters the cabinet air conditioner from the upper air inlet 701 or the lower air inlet 702, flows through the air duct 703 and the fan 704, and finally exits the cabinet air conditioner from the lower air inlet 702 or the upper air inlet 701 into the external environment. A heat exchanger is installed within the air duct 703. The heat exchanger has a first side and a second side on opposite sides. The first side of the heat exchanger is connected to the upper air outlet 701, and the second side is connected to the lower air outlet 702. Airflow in the air duct 703 flows through the heat exchanger in either the direction from the first side to the second side or vice versa, thereby exchanging heat with the heat exchanger. A first sensor group 2 and a second sensor group 3 are respectively installed on the first and second sides of the heat exchanger. The first sensor group 2 monitors the airflow before heat exchange with the heat exchanger and obtains a first airflow parameter. The second sensor group 3 monitors the airflow after heat exchange with the heat exchanger and obtains a second airflow parameter, providing a basis for adjusting the power of the heat exchanger.

[0044] The first airflow parameter involves airflow temperature, humidity, and flow rate, while the second airflow parameter involves airflow temperature, humidity, and flow rate.

[0045] In this embodiment, when the cabinet air conditioner starts running, the heat exchanger starts working and exchanges heat with the surrounding airflow. At the same time, the fan 704 also starts. The airflow enters the cabinet air conditioner from the upper air outlet 701 or the lower air outlet 702, flows through the air duct 703 and the fan 704, and finally flows out of the cabinet air conditioner from the lower air outlet 702 or the upper air outlet 701 into the external environment. The heat exchanger can be in a W-shaped structure to reduce wind resistance and increase the airflow in and out of the air duct. After passing through the heat exchanger, the airflow forms a heat exchange airflow. Before the airflow flows from the first side to the second side of the heat exchanger, the first sensor group 2 first acquires the state information of the external airflow to form the first airflow parameter. Based on the change of the first airflow parameter, the operating mode of the heat exchanger is adjusted so that the operating mode of the heat exchanger always matches the user's preset requirements. After passing through the first sensor group 2, the airflow continues to flow from the first side of the heat exchanger through the heat exchanger to the second side. During this process, the airflow exchanges heat with the heat exchanger to form a heat exchange airflow. The heat exchange airflow flows out from the second side of the heat exchanger. At this time, the second sensor group 3 acquires the state information of the heat exchange airflow to form the second airflow parameter. The second airflow parameter is compared and analyzed with the user's preset output parameter. Based on the comparison result, the operating mode of the heat exchanger is adjusted again so that the heat exchange effect of the cabinet air conditioner meets the user's preset requirements. The relative positioning of the dual sensor array and the heat exchanger inside the cabinet air conditioner enables the heat exchanger to reversibly detect airflow, allowing the cabinet air conditioner to more accurately monitor the state parameters of outdoor airflow and heat exchange airflow. This results in more precise temperature and humidity control and allows the cabinet air conditioner to flexibly adjust the airflow direction according to different operating modes (cooling or heating), achieving flexible airflow modes and improving the user experience.

[0046] The above settings can increase the air volume of the air duct 703 and the heat exchange efficiency of the heat exchanger, enabling the cabinet air conditioner to achieve rapid cooling or heating while also enabling flexible air supply modes and more precise control of the temperature and humidity of the external airflow and heat exchange airflow, thereby enhancing the user's comfort and improving the user experience.

[0047] Optionally, such as Figure 1-2 As shown, in one implementation of this embodiment,

[0048] The heat exchanger includes multiple heat exchange units 1, which are connected end-to-end in sequence. Here, "connected end-to-end" means, for example... Figure 1As shown, in the leftmost heat exchange unit 1, if the first end 103 is the head end of heat exchange unit 1, then the second end 104 is the tail end of heat exchange unit 1. In the heat exchange unit 1 adjacent to the leftmost heat exchange unit 1, the end that is close to the second end 104 is the head end of that heat exchange unit 1. Thus, multiple heat exchange units 1 are connected head to tail in sequence. However, the connection is not limited to being connected together; they can also be close to each other. Multiple heat exchange units 1 are connected together in a zigzag shape, forming a zigzag-shaped heat exchanger. The zigzag-shaped heat exchanger has a first zigzag-shaped surface on the upper side and a second zigzag-shaped surface on the lower side. The first zigzag-shaped surface is closer to the first side of the heat exchanger than the second zigzag-shaped surface, and the second zigzag-shaped surface is closer to the second side of the heat exchanger than the first zigzag-shaped surface.

[0049] In this embodiment, multiple heat exchange units 1 are connected end-to-end in a zigzag shape to form a zigzag-shaped heat exchanger. Depending on the number of heat exchange units 1, the heat exchanger can be V-shaped, N-shaped, or W-shaped. The first and second zigzag surfaces face each other and are located on the first and second sides of the heat exchanger, respectively. Using the same number of heat exchange units 1, compared to a conventionally shaped heat exchanger, the distance between the outer wall of the zigzag-shaped heat exchanger and the inner wall of the air duct 703 is greater. Therefore, the zigzag-shaped heat exchanger occupies less of the flow cross-sectional area of ​​the air duct 703, resulting in less resistance to airflow as it flows back and forth through the heat exchanger within the air duct 703. This increases the airflow volume in and out of the air duct 703, thereby improving the air outlet efficiency of the cabinet air conditioner.

[0050] Optionally, such as Figure 1-2 As shown, in one implementation of this embodiment,

[0051] The cabinet air conditioner also includes a support 4 for supporting the heat exchanger. The support 4 includes a base frame 401 and a enclosure 402. The base frame 401 is supported at the lower connection end of two adjacent heat exchange units 1. The enclosure 402 is arranged around the heat exchanger, thereby forming a cavity structure. A first opening 403 is formed at the lower end of the support 4, and a second opening 404 is formed at the upper end of the support 4. The first side of the heat exchanger faces the first opening 403, and the second side of the heat exchanger faces the second opening 404. The first opening 403 and the second opening 404 are in relative communication.

[0052] In this embodiment, the bracket 4, through the cavity structure formed by the base frame 401 and the enclosure 402, and the heat exchanger located within the cavity structure, can separate the external airflow before heat exchange from the heat exchanged airflow after heat exchange. When the external airflow enters the air duct 703, all the external airflow will flow into the cavity structure formed by the bracket 4 from the first opening 403 or the second opening 404, so as to ensure that all the external airflow can flow through the heat exchanger and exchange heat with it to form a heat exchanged airflow, thereby greatly reducing the escape of the external airflow and improving the heat exchange efficiency of the heat exchanger. After heat exchange, the heat exchanged airflow will flow out of the air duct 703 from the second opening 404 or the first opening 403 of the bracket 4 and enter the external environment of the cabinet air conditioner for heat exchange, thereby completing the heat exchange cycle of the cabinet air conditioner.

[0053] By setting a support 4 inside the air duct 703 and placing the heat exchanger inside the cavity structure formed by the support 4, all external airflow can flow through the heat exchanger and exchange heat with it to form a heat exchange airflow, thereby reducing the escape of external airflow and further improving the heat exchange efficiency of the heat exchanger.

[0054] Optionally, such as Figure 1 As shown, in one implementation of this embodiment,

[0055] The first sensor group 2 is placed at the top of the enclosure 402, or the second sensor group 3 is placed on the base frame 401, or the first sensor group 2 and the second sensor group 3 are placed at the top of the enclosure 402 and on the base frame 401 respectively.

[0056] In this embodiment, the heat exchanger is located within the cavity structure formed by the support 4. Therefore, the external airflow first flows through one end opening of the cavity structure, then contacts one end of the heat exchanger and exchanges heat with it. When the external airflow flows out from the other end opening of the cavity structure, it has already undergone heat exchange and formed a heat exchange airflow. Therefore, by placing the first sensor group 2 at the top of the enclosure 402, or placing the second sensor group 3 on the base frame 401, or simultaneously placing the first sensor group 2 and the second sensor group 3 at the top of the enclosure 402 and the base frame 401 respectively, the state of the external airflow can be monitored in advance, and the heat exchange airflow that has completed heat exchange can be monitored again to ensure that the operating mode of the heat exchanger can be adjusted to match the changes in the state of the external airflow and the heat exchange airflow. Placing the first sensor group 2 and the second sensor group 3 on the support 4 instead of on the heat exchanger reduces the space occupied by the heat exchanger within the cavity structure, allowing the heat exchanger to make full use of the space within the cavity structure for heat exchange, thereby further improving the heat exchange efficiency of the heat exchanger.

[0057] By setting the first sensor group 2 and the second sensor group 3 at the top of the enclosure 402 and the base frame 401 respectively, the operating mode of the heat exchanger can be adjusted to match the changes in the state of the external airflow and the heat exchange airflow, so that the heat exchanger can make full use of the space inside the cavity structure for heat exchange, thereby further improving the heat exchange efficiency of the heat exchanger.

[0058] Optionally, such as Figure 3 As shown, in one implementation of this embodiment,

[0059] The base frame 401 includes at least one frame plate, with multiple frame plates arranged at intervals and connected to each other. Each frame plate supports the lower connection ends of two adjacent heat exchange units 1 corresponding to it. A connection groove is formed on each frame plate, and the lower connection ends of the two adjacent heat exchange units 1 corresponding to the groove are embedded in the groove. A water receiving trough is also provided inside the connection groove, located at the bottom of the connection groove. A drain hole 501 is provided on the bottom wall of the water receiving trough, allowing condensate to flow into the water receiving trough along the connection groove or drip directly into the water receiving trough, collect in the water receiving trough, and finally discharge from the heat exchanger through the drain hole 501.

[0060] In this embodiment, the base frame 401 can be a single frame or multiple frames. Each frame is opposite to the second fold line on the lower side of the heat exchanger. When the heat exchanger is V-shaped, one frame is provided to support the bottom position of one tip of the heat exchanger. When the heat exchanger is W-shaped, two frames are provided to support the bottom positions of the two tips of the heat exchanger. When the heat exchanger has more V-shaped structures, frames are provided to support the multiple tips of the heat exchanger. When the base frame 401 includes multiple frames, there can be gaps or they can abut against each other between adjacent frames. This ensures that each heat exchange unit 1 has a certain tilt angle with the horizontal plane and that there is an included angle between adjacent heat exchange units 1, so that each heat exchange unit 1 can stably maintain its installation posture. When condensate is generated on the heat exchange surface of heat exchange unit 1, it flows downward to the lower connection end of heat exchange unit 1. Then, this condensate flows into the water receiving tank along the connection groove or drips directly into the water receiving tank, and gathers in the water receiving tank. Finally, it is discharged from the heat exchanger through the drain hole 501.

[0061] By setting connection grooves and water collection grooves on the frame plate, and setting the lower connection ends of two adjacent heat exchange units 1 in the same corresponding connection groove, condensate can be discharged quickly, preventing condensate from accumulating in the air duct 703 and breeding bacteria or odors. It can also improve the overall structural strength of the heat exchanger by stabilizing the connection posture of the two adjacent heat exchange units 1.

[0062] Optionally, such as Figure 1As shown, in one implementation of this embodiment,

[0063] At least one rack includes a first rack 4011 and a second rack 4012. A first connecting groove 4013 is formed on the first rack 4011. A first water receiving groove 5 is also provided inside the first connecting groove 4013. The first water receiving groove 5 is located at the lower part of the first connecting groove 4013. A second connecting groove 4014 is formed on the second rack 4012. A second water receiving groove 6 is provided inside the second connecting groove 4014. A drain hole is provided on the bottom wall of the second water receiving groove 6. The second water receiving groove 6 is connected to the first water receiving groove 5. Condensate can flow from the first water receiving groove 5 to the second water receiving groove 6 and be discharged to the outside of the heat exchanger through the drain hole 501.

[0064] In two adjacent heat exchange units 1, when the distance between the upper connection ends of the two heat exchange units 1 is greater than the distance between the lower connection ends of the two heat exchange units 1, there will be a corresponding first connection groove 4013 below the lower connection ends of the two heat exchange units 1. The lower connection ends of the two heat exchange units 1 are set in the same first connection groove 4013 below. At this time, the two adjacent heat exchange units 1 form a V-shaped structure.

[0065] In this embodiment, a first support plate 4011 corresponds to the lower part of each of the two adjacent heat exchange units 1 in a V-shape, and the lower connection ends of the two heat exchange units 1 are located in the same first connection groove 4013. Therefore, the condensate generated by the two heat exchange units 1 during the heat exchange process will flow along the surface of the heat exchange unit 1 to its lower connection end, and then flow from the lower connection end along the first connection groove 4013 to or drip directly into the first water receiving tank 5. The condensate flows in the first water receiving tank 5 to the second water receiving tank 6 on the second support plate 4012 for collection. Finally, all the condensate is discharged outward from the drain hole 501 on the bottom wall of the second water receiving tank 6, thereby preventing the condensate from accumulating in the air duct 703 and breeding bacteria or odors.

[0066] In this embodiment, the second support plate 4012 can be placed on the side of the heat exchanger, and one end of each of the multiple first support plates 4011 is connected to a second support plate 4012, and the other end of each of the multiple first support plates 4011 is connected to another second support plate 4012. This allows the entire base frame 401 to form a stable I-beam structure, enabling it to support a heavier heat exchanger and reducing the risk of deformation of the base frame 401 due to uneven stress during installation or transportation. A gap is provided between adjacent first support plates 4011, forming a hollow portion of the base frame 401. This reduces the weight of the base frame 401, further reducing the risk of deformation and improving the structural strength of the heat exchanger. The heat exchanger is supported by a stable, I-shaped base frame 401 with partial perforations. This reduces the weight of the base frame 401 and lowers the risk of deformation due to uneven stress during installation or transportation, thereby improving the structural strength of the heat exchanger. Condensate is guided to the second water collection tank 6 and then discharged. This allows the drainage components to be located on the side of the heat exchanger, avoiding the occupation of space in the middle of the air duct 703. This reduces the air resistance in the air duct 703 and increases the inlet and outlet airflow of the air duct 703.

[0067] The heat exchange unit assembly is supported by a stable I-shaped base frame with partial perforations, which reduces the weight of the base frame and the risk of deformation due to uneven stress during installation or transportation, thereby improving the structural strength of the evaporator heat exchanger. A second water receiving groove 6 connected to the first water receiving groove 5 is opened in the second connecting groove 4014 of the second frame plate 4012, which can drain the condensate from the side of the heat exchanger and avoid the drainage component occupying the space directly below the center of the heat exchanger, thereby reducing the wind resistance in the air duct 703 and increasing the inlet and outlet air flow of the air duct 703.

[0068] Optionally, such as Figure 1-3 As shown, in one implementation of this embodiment,

[0069] A first connector 4015 is provided at the end of the second frame plate 4012, and a second connector 4021 is provided at the bottom of the enclosure 402. The positions of the first connector 4015 and the second connector 4021 are corresponding. After the first connector 4015 and the second connector 4021 are fixedly connected, the enclosure 402 and the base frame 401 can be fixedly connected.

[0070] In this embodiment, when assembling the bracket 4, the second connecting piece 4021 at the bottom of the enclosure 402 is first aligned with the first connecting piece 4015 at the end of the second frame plate 4012. Then, the second connecting piece 4021 and the first connecting piece 4015 are fixedly connected using screws or pins, thereby completing the fixed connection between the enclosure 402 and the base frame 401. At this time, the bracket 4 is assembled. The second connecting piece 4021 and the first connecting piece 4015 are both located at one side corner of the heat exchanger. This design not only saves the installation space in the middle of the heat exchanger, but also further reduces the wind resistance in the air duct 703 and increases the air volume in and out of the air duct 703, thereby further improving the heat exchange efficiency of the heat exchanger.

[0071] Preferably, after the second connector 4021 at the bottom of the enclosure 402 is aligned with the first connector 4015 at the end of the second frame plate 4012, a portion of the bottom of the enclosure 402 will also be inserted into the second connecting groove 4014. The second connecting groove 4014 can limit the portion of the bottom of the enclosure 402, playing a pre-positioning role in the assembly process of the bracket 4, avoiding relative displacement between the enclosure 402 and the base frame 401, improving the fixed connection efficiency between the second connector 4021 and the first connector 4015, thereby speeding up the assembly speed of the bracket 4.

[0072] By fixing the second connector 4021 located at one corner of the heat exchanger to the first connector 4015, the fixed connection between the enclosure 402 and the base frame 401 can be achieved, the installation space in the middle of the heat exchanger can be saved, and the air volume of the air duct 703 can be further increased, thereby further improving the heat exchange efficiency of the heat exchanger.

[0073] Optionally, such as Figure 1 As shown, in one implementation of this embodiment,

[0074] Both the first sensor group 2 and the second sensor group 3 include temperature and humidity sensors, which can monitor the temperature and humidity of external airflow and heat exchange airflow.

[0075] In this embodiment, when the heat exchanger operates in cooling mode, the lower opening of the cavity structure of the support 4 serves as the air inlet, and the upper opening serves as the air outlet. External airflow enters the heat exchanger through the lower opening of the cavity structure of the support 4, and after passing through the heat exchanger, forms a heat exchange airflow that flows out of the heat exchanger through the upper opening of the cavity structure of the support 4. The first sensor group 2 can monitor the temperature and humidity of the external airflow before heat exchange occurs with the heat exchanger, thereby obtaining the first airflow parameters. The second sensor group 3 can monitor the temperature and humidity of the heat exchange airflow formed after cooling by the heat exchanger, thereby obtaining the second airflow parameters. Parameters: When the heat exchanger operates in heating mode, the upper opening of the cavity structure of bracket 4 serves as the air inlet, and the lower opening serves as the air outlet. External airflow enters the heat exchanger through the upper opening and, after passing through the heat exchanger, forms a heat-exchange airflow that exits from the lower opening. The second sensor group 3 monitors the temperature and humidity of the external airflow before it exchanges heat with the heat exchanger, thus obtaining the second airflow parameters. The first sensor group 2 monitors the temperature and humidity of the heat-exchange airflow formed after heating by the heat exchanger, thus obtaining the first airflow parameters. Finally, the control board of the cabinet air conditioner adjusts the operating mode of the heat exchanger based on the first and second airflow parameters obtained by the first and second sensor groups 2 and 3. The temperature and humidity parameters of the external airflow reflect the temperature and humidity of the air entering the cabinet air conditioner, thus reflecting the current air conditions of the environment in which the cabinet air conditioner is located. The temperature and humidity parameters of the heat-exchange airflow, after sufficient heat exchange with the heat exchanger, reflect the actual output effect of the cabinet air conditioner.

[0076] By coordinating the first sensor group 2 and the second sensor group 3, the cabinet air conditioner can more precisely adjust its operating parameters. For example, the cabinet air conditioner can dynamically adjust the cooling or heating power of the heat exchanger based on the first airflow parameter and the second airflow parameter to ensure that the temperature and humidity at the air outlet reach the user's desired set values.

[0077] Optionally, such as Figure 1 As shown, in one implementation of this embodiment,

[0078] Multiple heat exchange units 1 constitute a W-type heat exchanger.

[0079] In this embodiment, two adjacent heat exchange units 1 form a V-shaped structure. Each heat exchanger contains at least four heat exchange units 1. Therefore, the ends of multiple heat exchange units 1 are connected sequentially to form a zigzag shape. In this way, the upper and lower connecting ends of two adjacent heat exchange units 1 are connected together, thus forming a W-shaped heat exchanger within the support 4. The W-shaped heat exchanger can increase the heat exchange area of ​​the heat exchanger without changing the overall casing, thereby improving the heating and cooling capacity of the heat exchanger.

[0080] By combining multiple heat exchange units 1 to form a W-shaped heat exchanger, the overall length and height of the heat exchanger are reduced, and the distance between the heat exchanger component water receiving tray and the fan 704 is increased. This reduces the air resistance in the air duct 703 while increasing the air volume of the air duct 703. At the same time, by moving the heat exchanger away from the air outlet, the flow velocity of the heat exchange airflow is reduced, thereby reducing the loss of inflow impact and improving the heat exchange energy efficiency level of the cabinet air conditioner.

[0081] Optionally, such as Figure 4-7 As shown, in one implementation of this embodiment, the heat exchanger is located near the upper air outlet 701, the fan 704 is located between the heat exchanger and the lower air outlet 702, and the cabinet air conditioner includes a first air outlet mode and a second air outlet mode.

[0082] In this embodiment, when the cabinet air conditioner operates in the first air outlet mode, the fan 704 starts and blows air to the upper air outlet 701. The first air outlet mode can be a cooling mode. Under the action of wind pressure, the outside airflow enters the air duct 703 from the lower air outlet 702. The outside airflow enters the fan 704 from both sides of the air duct 703. After being pressurized by the fan 704, the outside airflow flows entirely to the heat exchanger, and then flows from the first side of the heat exchanger through the heat exchanger to the second side. During this process, the outside airflow undergoes sufficient heat exchange with the heat exchanger to form a cold airflow. Subsequently, the cold airflow is discharged from the upper air outlet 701 outside the cabinet air conditioner to exchange heat with the external environment. During this process, the second sensor group 3 monitors and continuously acquires the temperature and humidity of the outside airflow, and the first sensor group 2 monitors and continuously acquires the temperature and humidity of the cold airflow. Temperature and humidity; When the cabinet air conditioner is running in the second air outlet mode, which can be the heating mode, the fan 704 starts and blows air down to the air outlet 702. Under the action of wind pressure, the outside airflow enters the air duct 703 from the upper air outlet 701. The outside airflow first passes through the heat exchanger from the second side and flows to its first side. During this process, the outside airflow undergoes sufficient heat exchange with the heat exchanger to form a hot airflow. Subsequently, the hot airflow enters the fan 704 from both sides of the air duct 703. After being pressurized by the fan 704, the hot airflow is discharged from the cabinet air conditioner from the lower air outlet 702 to exchange heat with the external environment. During this process, the first sensor group 2 monitors and continuously acquires the temperature and humidity of the outside airflow, and the second sensor group 3 monitors and continuously acquires the temperature and humidity of the hot airflow.

[0083] By placing the heat exchanger close to the upper air outlet 701 and the fan 704 between the heat exchanger and the lower air outlet 702, and operating it in either the first or second air outlet mode, the cabinet air conditioner can quickly cool or heat, and increase the air intake and exhaust volume of the cabinet air conditioner, thereby rapidly changing the temperature of the external environment and improving the user experience.

[0084] Preferably, the outer casing 7 of the cabinet air conditioner includes a front panel 706 and a rear casing 705. The front panel 706 is fixed to the front of the rear casing 705. The upper air vent 701 is located above the rear casing 705 and the front panel 706. The lower air vent 702 is opened below the front panel 706. The heat exchanger is located above the air duct 703.

[0085] Optionally, in one implementation of this embodiment, the cabinet air conditioner further includes a controller, which is electrically connected to the first sensor group 2 and the second sensor group 3 respectively. The first airflow parameter obtained by the first sensor group 2 is the first detection signal, and the second airflow parameter obtained by the second sensor group 3 is the second detection signal. The cabinet air conditioner adjusts its operating parameters according to the first detection signal received by the controller from the first sensor group 2 and the second detection signal received from the second sensor group 3, so that the operating state of the cabinet air conditioner is more matched with the current external environment, thereby further improving the user's physical comfort.

[0086] In summary, the ingenious design of the cabinet air conditioner lies in:

[0087] First, the dual-sensor design enables the heat exchanger to reversibly detect airflow, allowing the cabinet air conditioner to more accurately monitor the state parameters of outdoor airflow and heat exchange airflow, thereby achieving more precise temperature and humidity control. It also allows the cabinet air conditioner to flexibly adjust the air supply direction according to different operating modes (cooling or heating), achieving flexible air supply modes and improving the user experience.

[0088] Secondly, by using a W-shaped heat exchanger with a zigzag shape, the encroachment on the cross-sectional area of ​​the air duct is reduced, thereby increasing the air volume entering and leaving the air duct and thus improving the air output efficiency of the cabinet air conditioner.

[0089] Third, by setting up a support in the air duct and placing the heat exchanger in the cavity structure formed by the support, all the external airflow can flow through the heat exchanger and exchange heat with it to form a heat exchange airflow, thereby reducing the escape of the external airflow and further improving the heat exchange efficiency of the heat exchanger.

[0090] Fourth, by setting the first sensor group and the second sensor group at the top of the enclosure and the base frame respectively, the operating mode of the heat exchanger can be adjusted to match the changes in the state of the external airflow and the heat exchange airflow, so that the heat exchanger can make full use of the space inside the cavity structure for heat exchange, thereby further improving the heat exchange efficiency of the heat exchanger.

[0091] Fifth, by setting connection grooves and water collection grooves on the frame plate, and setting the lower connection ends of two adjacent heat exchange units in the same corresponding connection groove, condensate can be discharged quickly, avoiding the accumulation of condensate in the air duct and the growth of bacteria or odors. It can also improve the overall structural strength of the heat exchanger by stabilizing the connection posture of the two adjacent heat exchange units 1.

[0092] Sixth, the heat exchange unit group is supported by a stable I-shaped base frame with partial perforations, which reduces the weight of the base frame and the risk of deformation due to uneven stress during installation or transportation, thereby improving the structural strength of the evaporator heat exchanger. A second water receiving groove connected to the first water receiving groove is opened in the second connecting groove of the second frame plate, which can drain the condensate from the side of the heat exchanger and avoid the drainage component occupying the space directly below the middle of the heat exchanger, thereby reducing the wind resistance in the air duct and increasing the airflow in and out of the air duct.

[0093] Seventh, by fixing the second connector located at one corner of the heat exchanger to the first connector, it is possible to achieve a fixed connection between the enclosure and the base frame, save installation space in the middle of the heat exchanger, and further increase the air volume of the duct, thereby further improving the heat exchange efficiency of the heat exchanger.
