Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to an air conditioner. Background Technology

[0002] Square cabinet air conditioners (referred to as "square cabinet air conditioners") are widely used in public places such as shopping malls, offices, and exhibition halls due to their large air volume, long air delivery distance, and suitability for cooling / heating in large spaces. Currently, square cabinet air conditioners are mainly divided into traditional models using centrifugal fans and newer models using axial fans, based on the type of fan used.

[0003] In traditional centrifugal square air conditioners, the evaporator typically adopts a flat-plate design and is arranged horizontally along the width of the air conditioner. This design results in the evaporator occupying a large space, increasing the overall width of the unit and making it appear bulky and cumbersome. This not only affects the product's aesthetics but also limits its installation and use in confined spaces.

[0004] From an aerodynamic perspective, the airflow generated by an axial fan exhibits a tapered (or conical) velocity distribution in a free flow field, meaning the air velocity is high at the center and gradually decreases towards the edges. If the traditional flat-plate evaporator design is directly adopted, when an axial-flow cabinet air conditioner is installed against a wall, the flat-plate evaporator is usually located at the rear of the unit and protrudes from the air inlet surface. This results in the evaporator being too close to the wall, severely hindering the smooth flow of air, causing poor air intake, which in turn leads to reduced airflow, decreased heat exchange efficiency, and affects the overall cooling / heating performance. Utility Model Content

[0005] The purpose of this utility model is to provide an air conditioner that can reduce the width of the casing and allow air to enter through the bent side of the evaporator when the casing is against a wall, thereby reducing the attenuation of air volume and ensuring heat exchange efficiency.

[0006] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides an air conditioner, comprising: The housing has a corresponding air inlet and air outlet; The air duct assembly is housed within the casing and includes fan blades, the axis of which is the airflow direction of the air conditioner. A heat exchange assembly is disposed within a housing and located between an air inlet and an air outlet. The heat exchange assembly includes a heat exchanger, which includes a first heat exchange section and a second heat exchange section connected at an angle. The opening formed by the first heat exchange section and the second heat exchange section faces the air outlet. The connection between the first heat exchange section and the second heat exchange section is located on one side of a first preset plane. The first preset plane includes the axis of the fan blade and is parallel to the height direction of the heat exchange assembly. The connection between the first heat exchange section and the second heat exchange section passes through the second preset plane, and the second preset plane forms an angle with the first preset plane.

[0007] The above settings reduce the required width of the casing and also mitigate airflow attenuation when the casing is against a wall, thus ensuring heat exchange efficiency.

[0008] In an optional implementation, at least one of the air inlet and air outlet is symmetrical about a first preset plane.

[0009] With the above settings, air can flow in a straight line when the fan blades are rotating, reducing the turning or deflection of the airflow, effectively reducing the flow resistance of the airflow, reducing energy loss, and thus improving the air delivery capacity.

[0010] In an optional embodiment, the connection between the first heat exchanger and the second heat exchanger is located on the side of the first preset plane closer to the first heat exchanger. The end of the first heat exchanger that is away from the second heat exchanger is the first end, and the end of the second heat exchanger that is away from the first heat exchanger is the second end. The first end is closer to the air outlet than the second end.

[0011] The above configuration can further reduce the space occupied by the heat exchanger in the width direction of the shell, further compress the overall width of the machine, and also reserve space on one side of the second end of the second heat exchange section for the installation of evaporator piping.

[0012] In an optional embodiment, the first heat exchange section and the second heat exchange section are symmetrical about a second preset plane, and the angle between the first preset plane and the second preset plane is β, where β is 6~10°.

[0013] By adopting the above settings, the space occupied by the heat exchanger in the width direction of the shell is reduced, and the uneven heat exchange caused by excessive rotation angle of the heat exchanger is avoided. In addition, space can be reserved on one side of the second end of the second heat exchange section for the installation of evaporator piping.

[0014] In an optional embodiment, the heat exchange assembly includes multiple heat exchangers, which are stacked and arranged along the direction from the air inlet to the air outlet. The first heat exchange section of the multiple heat exchangers is arranged in a stepped manner, and the distance between the first end of the first heat exchange section and the first preset plane is a first distance. The distance of the first distance gradually increases along the direction from the air inlet to the air outlet.

[0015] The above settings ensure that the copper tubes in the heat exchanger near the air inlet are of relatively consistent length with those in the heat exchanger near the air outlet, thus improving the consistency of the heat exchange components.

[0016] In an optional embodiment, the angle between the first heat exchange section and the second heat exchange section is α, where α is 120°~160°.

[0017] The above settings ensure that the heat exchanger is perpendicular to the airflow direction and the airflow is relatively smooth, which means that the fins are as parallel to the airflow direction as possible.

[0018] In an optional embodiment, the housing includes a rear panel and a front shell, with an air inlet located on the rear panel and an air outlet located on the front shell. The heat exchange assembly also includes an electric heating assembly. The air duct assembly includes an air duct casing, a motor bracket, and fan blades. The heat exchanger, electric heating assembly, motor bracket, and fan blades gradually approach the air outlet. The maximum distance between the rear panel and the front shell is a preset distance C. Along the direction from the air outlet to the air inlet, the minimum distance between the inner wall of the rear panel and the heat exchange assembly is C1, where 0.03C < C1 < 0.1C.

[0019] The above design reduces the risk of collision between the rear panel and the heat exchange components, and also avoids making the overall housing size too large.

[0020] In an optional embodiment, the shape of the electric heating component is adapted to the shape of the heat exchange component, and the minimum distance between the electric heating component and the heat exchange component is C2, where 0.02C < C2 < 0.1C. And / or, the minimum distance between the electric heating element and the motor bracket is C3, where 0.02C < C3 < 0.1C.

[0021] The above settings reduce the impact of the electric heating component on the air intake of the heat exchange component, as well as the impact on the size of the housing; they also reduce the impact of the electric heating component on the motor bracket, and further reduce the impact on the size of the housing.

[0022] In an optional implementation, the minimum distance between the motor bracket and the fan blade is C4, where 0.04C < C4.

[0023] The above settings can prevent interference between the motor bracket and the fan blades, and also reduce the impact on the size of the housing.

[0024] In an optional implementation, C1 is 28~32mm; And / or, the shape of the electric heating component is adapted to the shape of the heat exchange component, and the minimum distance between the electric heating component and the heat exchange component is C2, where C2 is 18~22mm; And / or, the minimum distance between the electric heating element and the motor bracket is C3, where C3 is 13~17mm; And / or, the minimum distance between the motor bracket and the fan blade is C4, where C4 is 45~55mm.

[0025] The beneficial effects provided by this embodiment of the utility model include: An air conditioner provided by this embodiment of the utility model includes a housing, a duct assembly, and a heat exchange assembly. The housing has opposing air inlets and outlets. The duct assembly is disposed within the housing and includes fan blades. The axial direction of the fan blades is the airflow direction of the air conditioner. The heat exchange assembly is disposed within the housing and located between the air inlet and outlet. The heat exchange assembly includes a heat exchanger, which includes a first heat exchange section and a second heat exchange section connected at an angle. The opening formed by the first and second heat exchange sections faces the outlet. The connection point between the first and second heat exchange sections is located on one side of a first preset plane. The first preset plane includes the axis of the fan blades and is parallel to the height direction of the heat exchange assembly. The connection point between the first and second heat exchange sections passes through a second preset plane, which forms an angle with the first preset plane. In this embodiment, the heat exchanger is approximately V-shaped and deflected. Compared to a flat plate heat exchanger, with the same evaporator area, the width of the housing can be reduced. Moreover, when the housing is against a wall, air can still enter through the heat exchanger from the side, reducing the attenuation of airflow. Attached Figure Description

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] The following describes in detail, with reference to the accompanying drawings, the specific structure of an air conditioner provided by this utility model and its corresponding technical effects.

[0036] Please refer to Figures 1-3 An air conditioner 1 provided in this application embodiment includes a housing 100, an air duct assembly, and a heat exchange assembly 200. The housing 100 has an air inlet 111 and an air outlet 121. The air duct assembly is disposed on the housing 100 and includes a fan blade 500. The axial direction of the fan blade 500 is the airflow direction inside the air conditioner 1. That is, the fan inside the air conditioner 1 provided in this embodiment is an axial flow fan.

[0037] The heat exchange assembly 200 is disposed inside the housing 100 and located between the air inlet 111 and the air outlet 121. The heat exchange assembly 200 includes a heat exchanger 210, which includes a first heat exchange section 211 and a second heat exchange section 212 connected at an angle. The opening formed by the first heat exchange section 211 and the second heat exchange section 212 faces the air outlet 121. The connection between the first heat exchange section 211 and the second heat exchange section 212 is located on one side of a first preset plane 1001. The first preset plane 1001 includes the axis of the fan blade 500 and is parallel to the height direction of the heat exchange assembly 200. The connection between the first heat exchange section 211 and the second heat exchange section 212 passes through a second preset plane 1002, which forms an angle with the first preset plane 1001.

[0038] It should be noted that the heat exchanger 210 in this embodiment can be understood as an evaporator. The evaporator provided in this embodiment includes a first heat exchange section 211 and a second heat exchange section 212 connected at an angle. That is to say, the heat exchanger 210 in this embodiment is roughly V-shaped and deflected. Compared with a flat plate heat exchanger 210, the width of the shell 100 can be reduced under the same evaporator area. Moreover, when the shell 100 is against the wall, air can still enter through the heat exchanger 210 from the side, reducing the attenuation of air volume.

[0039] It should be noted that, with Figure 1 For reference, the height direction in this embodiment is... Figure 1 In the direction of a.

[0040] At least one of the air outlet 121 and the air inlet 111 is symmetrically arranged about the first preset plane 1001. Specifically, both the air outlet 121 and the air inlet 111 can be symmetrically arranged about the first preset plane 1001. Therefore, when the fan blades rotate, the air can flow in a straight line, reducing the turning or deflection of the airflow, effectively reducing the flow resistance of the airflow, reducing energy loss, and thus improving the air delivery capacity.

[0041] When the air conditioner 1 provided in this embodiment is applied to an axial flow fan, the airflow generated by the axial flow fan exhibits a gradually narrowing (or conical) velocity distribution in the free flow field, that is, the wind speed is high at the center and gradually decreases at the edge. The evaporator in this application, which is roughly V-shaped, matches the natural flow field of the axial flow fan, avoiding the problems of excessive wind resistance at the center and wasted airflow at the edge that exist in traditional flat plate evaporators. This makes the airflow distribution more uniform, reduces dead zones and turbulence losses, thereby improving the airflow utilization rate, heat exchange efficiency and fan operating efficiency, and helps to improve the overall energy efficiency ratio.

[0042] As is easily understood, evaporators typically have a protruding U-tube on one side along their width, while the other side does not. Figure 1For reference, the second heat exchange section 212 in the heat exchanger 210 is provided with a protruding U-tube, that is, the right side of the heat exchanger 210 is provided with a protruding U-tube. Therefore, since the right side of the evaporator needs to reserve space for arranging U-shaped pipes, while the left side does not need to be piped, if the heat exchanger 210 is also designed symmetrically about the first preset plane 1001, the space on the left side will be wasted.

[0043] For ease of subsequent description, the end of the first heat exchange section 211 that is away from the second heat exchange section 212 is called the first end 213, and the end of the second heat exchange section 212 that is away from the first heat exchange section 211 is called the second end 214.

[0044] In this embodiment, the connection between the first heat exchanger 211 and the second heat exchanger 212 is located on the side of the first preset plane 1001 closer to the first heat exchanger 211. The first end 213 is closer to the air outlet 121 than the second end 214. In other words, in this embodiment, the heat exchanger 210 is rotated relative to the connection between the first heat exchanger 211 and the second heat exchanger 212 towards the first heat exchanger 211, so that the first end 213 is closer to the air outlet 121 than the second end 214. This arrangement not only allows space for the evaporator pipeline to be installed on the side of the second end 214 of the second heat exchanger 212, but also further reduces the space occupied by the heat exchanger 210 in the width direction of the housing 100, further compressing the overall width of the machine.

[0045] In this embodiment, the connection between the first heat exchanger 211 and the second heat exchanger 212 is located on the side of the first preset plane 1001 closer to the first heat exchanger 211. That is, the connection between the first heat exchanger 211 and the second heat exchanger 212 in this embodiment is relatively close to the left side, which makes full use of the left-side space, avoids ineffective areas, and makes the overall layout more compact. This design reduces the overall width of the unit without sacrificing the heat exchange area and piping layout requirements.

[0046] The first heat exchange section 211 and the second heat exchange section 212 are symmetrical about the second preset plane 1002. The angle between the first preset plane 1001 and the second preset plane 1002 is β, which is 6~10°. Since β is 6~10°, the space occupied by the heat exchanger 210 in the width direction of the shell 100 is reduced, and the uneven heat exchange caused by the excessive rotation angle of the heat exchanger 210 is also avoided.

[0047] In detail, in this embodiment, the angle β between the first preset plane 1001 and the second preset plane 1002 is 8°. Of course, in some embodiments, β can also be 6°, 7°, 9° or 10°.

[0048] In this embodiment, the angle between the first heat exchange section 211 and the second heat exchange section 212 is α, where α is 120°~160°. This ensures that the heat exchanger 210 has a relatively smooth airflow direction perpendicular to the airflow direction, meaning that the fins are as parallel to the airflow direction as possible. Preferably, in this embodiment, α is 140°. Of course, in other embodiments, α can also be 120°, 125°, 130°, 135°, 145°, 150°, 155°, or 160°.

[0049] Please refer to Figure 4 In detail, in this embodiment, the heat exchange assembly 200 includes a plurality of heat exchangers 210. The plurality of heat exchangers 210 are stacked and arranged along the direction from the air inlet 111 to the air outlet 121, and the first heat exchange part 211 of the plurality of heat exchangers 210 is arranged in a stepped manner. The distance between the first end 213 of the first heat exchange part 211 and the first preset plane 1001 is the first distance. The distance of the first distance gradually increases along the direction from the air inlet 111 to the air outlet 121.

[0050] In other words, the distance between the first end 213 of the first heat exchange section 211 near the air outlet 121 and the first preset plane 1001 is greater than the distance between the first end 213 of the first heat exchange section 211 away from the air outlet 121 and the first preset plane 1001. It should be noted that "multiple" in this embodiment can be understood as two or more quantities.

[0051] Therefore, it can be ensured that the copper tubes in the heat exchanger 210 near the air inlet 111 and the copper tubes in the heat exchanger 210 near the air outlet 121 have relatively consistent lengths, thereby improving the consistency of the heat exchange components 200 and ensuring that the heat exchange effect of the multiple stacked heat exchangers 210 is relatively uniform.

[0052] Please continue to refer to this. Figures 1-3 Optionally, the housing 100 includes a rear panel 110 and a front housing 120, with an air inlet 111 disposed on the rear panel 110 and an air outlet 121 disposed on the front housing 120. The heat exchange assembly 200 also includes an electric heating assembly 300, and the air duct assembly also includes an air duct volute, a motor bracket 400, and a fan blade 500. The heat exchange assembly 200, the electric heating assembly 300, the motor bracket 400, and the fan blade 500 gradually approach the air outlet 121. The maximum distance between the rear panel 110 and the front housing 120 is a preset distance C. Along the direction from the air outlet 121 to the air inlet 111, the minimum distance between the inner wall of the rear panel 110 of the housing 100 and the heat exchange assembly 200 is C1, where 0.03C < C1 < 0.1C.

[0053] Understandably, if the minimum distance C1 between the evaporator and the rear panel 110 is too small, there is a risk of collision between the rear panel 110 and the evaporator during transportation. If it is too large, it will increase the size of the shell 100. 0.03C < C1 < 0.1C can reduce the risk of collision between the rear panel 110 and the heat exchange component 200, and can also avoid the entire shell 100 from being too large.

[0054] For example, the size of C1 is 28~32mm. Optionally, the size of C1 can be 28mm, 29mm, 30mm, 31mm or 32mm, which reduces the risk of collision between the rear panel 110 and the evaporator, and also reduces the space occupied by the housing 100.

[0055] It should be noted that the fan provided in this embodiment is an axial flow fan, and the fan blade 500 in this embodiment can be understood as an axial flow fan blade 500.

[0056] Optionally, the shape of the electric heating component 300 is adapted to the shape of the heat exchange component 200 to ensure that the gas after passing through the heat exchanger 210 passes through the electric heating component 300 relatively uniformly, thereby ensuring the uniformity of heating of the gas by the electric heating component 300. The minimum distance between the electric heating component 300 and the heat exchanger 210 is C2, specifically, 0.02C < C2 < 0.1C. C2 is 18~22mm, for example, C2 is 18mm, 19mm, 20mm, 21mm or 22mm. It is understood that if the distance between the electric heating component 300 and the heat exchanger 210 is too small, the electric heating component 300 will block the air intake of the evaporator. If C2 is too large, it will also increase the size of the shell 100. C2 of 18~22mm reduces the impact of the electric heating component 300 on the air intake of the evaporator and also reduces the impact on the size of the shell 100.

[0057] Optionally, the minimum distance between the electric heating element 300 and the motor bracket 400 is C3, where 0.02C < C3 < 0.1C. C3 is 13~17mm, for example, C3 is 13mm, 14mm, 15mm, 16mm or 17mm. If the distance between the electric heating element 300 and the motor bracket 400 is too small, it may cause the service life of the motor; if it is too large, it will increase the size of the entire housing 100. A distance of 13~17mm for C3 can reduce the impact of the electric heating element 300 on the motor bracket 400 and also reduce the impact on the size of the housing 100.

[0058] Optionally, the minimum distance between the motor bracket 400 and the fan blade 500 is C4, specifically, 0.04C < C4. C4 is 45~55mm, for example, C4 is 45mm, 46mm, 47mm, 48mm, 49mm, 50mm, 51mm, 52mm, 53mm, 54mm or 55mm. If the minimum distance between the motor bracket 400 and the fan blade 500 is too small, it will easily cause interference between the motor bracket 400 and the fan blade 500; if it is too large, it will increase the size of the housing 100.

[0059] In this embodiment, C4 is 45~55mm, which can avoid interference between the motor bracket 400 and the fan blade 500, and also reduce the impact on the size of the housing 100, thus avoiding excessively increasing the size of the housing 100.

[0060] In summary, the air conditioner 1 provided by this embodiment of the present invention includes a housing 100, an air duct assembly, and a heat exchange assembly 200. The housing 100 has opposing air inlets 111 and air outlets 121. The air duct assembly is disposed within the housing 100 and includes fan blades 500, the axis of which is the airflow direction within the air conditioner 1. The heat exchange assembly 200 is disposed within the housing 100 and located between the air inlet 111 and the air outlet 121. The heat exchange assembly 200 includes a heat exchanger 210, which includes a first heat exchanger connected at an angle. The first heat exchanger 211 and the second heat exchanger 212 form an opening facing the air outlet 121. The connection between the first heat exchanger 211 and the second heat exchanger 212 is located on one side of the first preset plane 1001. The first preset plane 1001 includes the axis of the fan blade 500 and is parallel to the height direction of the heat exchange assembly 200. The connection between the first heat exchanger 211 and the second heat exchanger 212 passes through the second preset plane 1002, which forms an angle with the first preset plane 1001. In this embodiment, the heat exchanger 210 is approximately V-shaped. Compared to a flat-plate heat exchanger 210, with the same evaporator area, the width of the shell 100 can be reduced. Moreover, when the shell 100 is against a wall, air can still enter through the heat exchanger 210 from the side, reducing the attenuation of airflow. Furthermore, it can make full use of the left-side space, avoiding ineffective areas and making the overall layout more compact. This design reduces the overall width of the unit without sacrificing the heat exchange area and piping layout requirements.
