Description

Technical Field

[0001] This application belongs to the field of air conditioning technology, specifically relating to a fan coil structure and an air conditioner. Background Technology

[0002] A fan coil unit is one of the terminal devices in an air conditioning system, consisting of a fan and a heat exchanger. The heat exchanger exchanges heat with the air around it, cooling or heating the air to regulate the indoor air temperature.

[0003] A fan coil unit also includes a fan housing, which contains air ducts. The fan is located inside the air ducts, and the heat exchanger is located on one side of the air ducts. The fan drives the airflow along the air ducts to the heat exchanger.

[0004] However, the airflow velocity in the upper region of the heat exchanger relative to the duct is greater than that in the lower region of the heat exchanger relative to the duct, and also greater than that in the region of the heat exchanger not relative to the duct. This results in uneven airflow velocity around the heat exchanger, affecting the heat exchange efficiency of the heat exchanger. Utility Model Content

[0005] This application provides a fan coil structure and an air conditioner to solve the problem of uneven airflow velocity around the heat exchanger, which affects the heat exchange efficiency of the heat exchanger.

[0006] In a first aspect, this application provides a fan coil unit structure, comprising:

[0007] A fan housing having at least one air supply channel;

[0008] The fan is correspondingly installed in the air supply duct;

[0009] A heat exchanger is located on one side of the fan housing, and the fan is used to drive the airflow in the air supply channel toward the first area on the heat exchanger.

[0010] A flow guide is disposed within the air supply channel. The flow guide is used to guide a portion of the airflow within the air supply channel toward the second region on the heat exchanger, and a portion of the second region is located within the first region.

[0011] In some possible implementations, the air supply channel has an air outlet at one end near the heat exchanger, and the heat exchanger is opposite to the air outlet;

[0012] The air guide is disposed inside the air outlet, and the air guide has a guiding surface. The guiding surface is used to change the direction of part of the airflow inside the air outlet so that part of the airflow flows toward the second region.

[0013] In some possible implementations, the guide surface forms an angle with the airflow direction within the air supply channel to alter the flow direction of a portion of the airflow within the air supply channel. In some possible implementations, the guide surface includes at least one of a convex arc surface, a concave arc surface, and an inclined surface.

[0014] In some possible implementations, the flow guide is detachably connected to the fan housing, or the flow guide is integrally formed with the fan housing.

[0015] In some possible implementations, the air supply channel has an air outlet at one end near the heat exchanger, the air outlet being square, and the guide member being located above the air outlet.

[0016] In some possible implementations, the air guide does not completely cover the upper side of the air outlet.

[0017] In some possible implementations, the fan housing includes a partition and at least one shell portion, the fan being disposed correspondingly within the shell portion, and the partition having at least one flow passage.

[0018] The shell portion is correspondingly inserted into the flow passage and connected to the periphery of the corresponding flow passage. The shell portion has the air supply channel inside, and the flow guide is disposed on the inner wall of the shell portion.

[0019] Alternatively, one side of the shell is connected to the periphery of the flow passage, and the interior of the shell communicates with the flow passage to jointly form the air supply channel, with the guide member disposed on the wall of the flow passage.

[0020] In some possible implementations, there are at least two air supply channels, and each air supply channel is arranged at intervals along a preset direction;

[0021] There are at least two air guides, and each air guide is correspondingly arranged in each of the air supply channels.

[0022] Secondly, this application provides an air conditioner, including a housing and any of the fan coil structures described in the first aspect located within the housing.

[0023] The fan coil structure and air conditioner provided in this application include a fan in the fan coil structure that drives airflow in the air supply channel toward a first region on the heat exchanger, and a guide member that guides a portion of the airflow in the air supply channel toward a second region on the heat exchanger. A portion of the second region is located within the first region, while the remaining portion is located outside the first region. The airflow velocity within the first region is greater than the airflow velocity outside the first region. Therefore, by guiding a portion of the airflow in the air supply channel toward a region on the heat exchanger with lower airflow velocity, the flow velocity in the region with lower airflow velocity on the heat exchanger is increased, thereby improving the uniformity of airflow velocity on the heat exchanger and increasing the heat exchange efficiency of the heat exchanger.

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] In existing technology, a fan coil unit includes a heat exchanger, a fan housing, and at least two fans. The fan housing has at least two air ducts, with each fan positioned within a corresponding air duct. The heat exchanger is located on one side of each air duct. The fans drive airflow along the air ducts to the heat exchanger. The heat exchanger exchanges heat with the air around it, cooling or heating the air to regulate indoor air parameters. However, because the air ducts cannot be aligned with the entire heat exchange area of ​​the heat exchanger, the airflow velocity in the area where the heat exchanger is aligned with the air duct is greater than the airflow velocity in the area where the heat exchanger is not aligned with the air duct. Furthermore, because the fans drive more airflow towards the upper area of ​​the part of the heat exchanger aligned with the air duct, the airflow velocity in the upper area of ​​this part is greater than the airflow velocity in the lower area. This results in uneven airflow velocity around the heat exchanger, affecting its heat exchange efficiency.

[0044] Based on this, this application provides a fan coil structure. A fan drives airflow within the air supply channel to flow towards a first region on the heat exchanger. A guide member directs a portion of the airflow within the air supply channel towards a second region on the heat exchanger. A portion of the second region is located within the first region, while the remaining portion is located outside the first region. The airflow velocity within the first region is greater than the airflow velocity outside the first region. Thus, by guiding a portion of the airflow within the air supply channel towards a region on the heat exchanger with lower airflow velocity, the flow velocity in this region is increased, thereby improving the uniformity of airflow velocity on the heat exchanger and enhancing its heat exchange efficiency.

[0045] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Similar or identical concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0046] Reference Figures 1 to 9 The fan coil structure provided in this application embodiment includes: a fan housing 100, a fan 200, a heat exchanger 300, and a guide member 400. The fan housing 100 has at least one air supply channel 130, and the fan 200 is correspondingly disposed within the air supply channel 130. The heat exchanger 300 is located on one side of the fan housing 100, and the fan 200 is used to drive the airflow within the air supply channel 130 to flow toward a first region on the heat exchanger 300. The guide member 400 is correspondingly disposed within the air supply channel 130, and the guide member 400 is used to guide a portion of the airflow within the air supply channel 130 to flow toward a second region on the heat exchanger 300, with a portion of the second region located within the first region.

[0047] The heat exchanger 300 is used to exchange heat with the airflow around the heat exchanger 300 to increase or decrease the temperature of the airflow.

[0048] The heat exchanger 300 includes a copper tube and multiple fins. The copper tube passes through the fins and is used for refrigerant flow. When the airflow approaches the copper tube, the refrigerant exchanges heat with the airflow through the copper tube to lower or raise the airflow temperature. When the airflow velocity near the copper tube is high, the airflow near the copper tube alternates quickly, and the copper tube can always exchange heat with the airflow with a large temperature difference from the copper tube, resulting in high heat exchange efficiency between the copper tube and the airflow. When the airflow velocity near the copper tube is low, the airflow near the copper tube alternates slowly, causing the temperature of the airflow near the copper tube to approach that of the copper tube, resulting in lower heat exchange efficiency between the copper tube and the airflow.

[0049] The airflow velocity in the upper region of the heat exchanger 300 is greater than that in the lower region of the heat exchanger 300. The guide member 400 is used to guide part of the airflow in the air supply channel 130 toward the lower part of the heat exchanger 300 to improve the uniformity of the airflow velocity on the heat exchanger 300, thereby improving the heat exchange efficiency of the heat exchanger 300.

[0050] In some examples, the heat exchanger 300 may be arranged at an angle relative to the horizontal plane to increase the heat exchange area of ​​the heat exchanger 300 and improve its heat exchange efficiency. Specifically, the distance between the upper part of the heat exchanger 300 and the fan housing 100 is greater than the distance between the lower part of the heat exchanger 300 and the fan housing 100.

[0051] Specifically, a portion of the second region is located within the first region, while the remaining portion of the second region is located outside the first region. The fan 200 drives the airflow within the air supply channel 130 to flow through the air supply channel 130 to the first region on the heat exchanger 300. The airflow velocity within the first region on the heat exchanger 300 is greater than the airflow velocity outside the first region, and the airflow velocity within the first region on the heat exchanger 300 is also uneven, resulting in uneven airflow velocity on the heat exchanger 300. The guide member 400 guides a portion of the airflow within the air supply channel 130 to the portion of the second region on the heat exchanger 300 located outside the first region. Simultaneously, the guide member 400 can guide a portion of the airflow within the air supply channel 130 to the portion of the second region located within the first region where the flow velocity is lower. Therefore, by guiding a portion of the airflow within the air supply channel 130 to the region on the heat exchanger 300 where the airflow velocity is lower, the uniformity of the airflow velocity on the heat exchanger 300 can be improved.

[0052] The fan coil structure provided in this application embodiment includes a fan 200 that drives airflow within the air supply channel 130 to flow toward a first region on the heat exchanger 300, and a guide 400 that guides a portion of the airflow within the air supply channel 130 toward a second region on the heat exchanger 300. A portion of the second region is located within the first region, while the remaining portion is located outside the first region. The airflow velocity within the first region is greater than the airflow velocity outside the first region. Therefore, the guide 400 can guide a portion of the airflow within the air supply channel 130 toward a region on the heat exchanger 300 with a lower airflow velocity, increasing the velocity of that region on the heat exchanger 300. This, in turn, improves the uniformity of the airflow velocity on the heat exchanger 300 and enhances the heat exchange efficiency of the heat exchanger 300.

[0053] Reference Figure 3 and Figure 5In a specific implementation, the air supply channel 130 has an air outlet 131 at one end near the heat exchanger 300, and the heat exchanger 300 is opposite to the air outlet 131. A flow guide 400 is disposed inside the air outlet 131, and the flow guide 400 has a flow guide surface 410. The flow guide surface 410 is used to change the flow direction of part of the airflow inside the air outlet 131, so that part of the airflow flows toward the second region.

[0054] The guide surface 410 is located on the side of the guide member 400 facing the fan 200. Part of the airflow within the air outlet 131 contacts the guide surface 410, changing its flow direction. The airflow then flows along the guide surface 410 towards the second region on the heat exchanger 300. By placing the guide member 400 within the air outlet 131, it facilitates the guidance of a portion of the airflow within the air outlet 131 towards the second region on the heat exchanger 300.

[0055] In practice, the guide surface 410 and the airflow direction in the air supply channel 130 are at an angle to change the airflow direction of some of the airflow in the air supply channel 130.

[0056] In this way, after a portion of the airflow in the air outlet 131 comes into contact with the guide surface 410, the flow direction of that portion of the airflow changes, and it flows along the guide surface 410 toward the second region on the heat exchanger 300.

[0057] Reference Figure 7 , Figure 8 and Figure 9 In some embodiments, the air guide 400 has a symmetry plane 401, and the air guide surface 410 is symmetrical with respect to the symmetry plane 401. The air outlet 131 is symmetrical with respect to the plane containing the symmetry plane 401.

[0058] In this way, the guide surface 410 can guide the airflow in the air outlet 131 to the left and right sides of the air outlet 131 more evenly, thereby making the airflow velocity of the airflow flowing to the heat exchanger 300 through the left and right sides of the air outlet 131 more even.

[0059] For example, the number of guide surfaces 410 is one, and the guide surface 410 is symmetrical with respect to the symmetry surface 401. Alternatively, the number of guide surfaces 410 is at least two, and the number of guide surfaces 410 is even, with each guide surface 410 corresponding to another, and the corresponding two guide surfaces 410 are symmetrical with respect to the symmetry surface 401. Alternatively, the number of guide surfaces 410 is at least three, and the number of guide surfaces 410 is odd, with one guide surface 410 intersecting with the symmetry surface 401 and being symmetrical with respect to the symmetry surface 401, and the remaining guide surfaces 410 being symmetrical with respect to the symmetry surface 401 in pairs.

[0060] Furthermore, the guide member 400 has a first connecting surface 420 and a second connecting surface. The first connecting surface 420 is connected to the guide surface 410, and the second connecting surface connects the first connecting surface 420 and the guide surface 410. Both the first connecting surface 420 and the second connecting surface can be planar, and the first connecting surface 420 can be perpendicular to the second connecting surface.

[0061] Reference Figure 7 , Figure 8 and Figure 9 In some embodiments, the guide surface 410 includes at least one of a convex arc surface, a concave arc surface, and a slope surface.

[0062] Reference Figure 7 In some examples, there may be one guide surface 410, which may be a convex arc surface and symmetrical with respect to the symmetry plane 401. The first connecting surface 420 is an isosceles triangle or an isosceles trapezoid, and the second connecting surface may be a semicircle. The two straight sides of the guide surface 410 are connected to the two sides of the first connecting surface 420. The arc side of the guide surface 410 is connected to the second connecting surface. Thus, the guide surface 410 can guide part of the airflow in the air outlet 131 to the area below the heat exchanger 300 and to the opposite sides of the air outlet 131.

[0063] Reference Figure 8 In other examples, the guide element 400 is a triangular pyramid shape, with two guide surfaces 410. Each guide surface 410 is an inclined plane, and the two guide surfaces 410 are connected and symmetrical with respect to the plane of symmetry 401. Both the first connecting surface 420 and the second connecting surface are isosceles triangles, with the two sides of the first connecting surface 420 and the two sides of the second connecting surface respectively connecting to the two guide surfaces 410. The two guide surfaces 410 are inclined towards the lower left and lower right sides of the air outlet 131, respectively. Thus, some airflow within the air outlet 131 can be guided to both sides of the air outlet 131 through the two guide surfaces 410, and simultaneously, both guide surfaces 410 can guide some airflow to the lower part of the heat exchanger 300.

[0064] Reference Figure 9 In other examples, there are two guide surfaces 410, which are concave arc surfaces, and the two guide surfaces 410 are symmetrical with respect to the symmetry plane 401. The first connecting surface 420 and the second connecting surface each have two arc edges, and the arc edges of the first connecting surface 420 and the second connecting surface are connected to the two guide surfaces 410 respectively.

[0065] In some embodiments, the flow guide 400 is detachably connected to the fan housing 100, or the flow guide 400 is integrally formed with the fan housing 100.

[0066] The guide component 400 is detachably connected to the fan housing 100, facilitating its removal from the fan housing 100 for maintenance and replacement. The guide component 400 and fan housing 100 are integrally molded, eliminating the need for assembly steps and improving production efficiency. This also enhances the structural integrity and strength of both the guide component 400 and the fan housing 100.

[0067] For example, the guide member 400 has a mounting portion that is detachably connected to the fan housing 100, so that the guide member 400 and the fan housing 100 are detachably connected. For example, the connection between the mounting portion and the fan housing 100 can be a snap-fit ​​or a threaded connection, etc.

[0068] Furthermore, the mounting part can be located on the first connecting surface 420.

[0069] Reference Figure 5 and Figure 6 In some embodiments, the air supply channel 130 has an air outlet 131 at one end near the heat exchanger 300. The air outlet 131 is square, and the guide member 400 is located on the upper side of the air outlet 131.

[0070] In this design, the airflow velocity in the upper region of the heat exchanger 300 is greater than that in the lower region. The upper region of the heat exchanger 300 is opposite to the upper part of the air outlet 131, and the lower region of the heat exchanger 300 is opposite to the lower part of the air outlet 131. By placing the guide member 400 on the upper side of the air outlet 131, a portion of the airflow within the air outlet 131 is guided towards the lower region of the heat exchanger 300, thereby improving the uniformity of the airflow velocity on the heat exchanger 300.

[0071] For example, the air guide 400 is disposed in the middle region of the upper side of the air outlet 131.

[0072] In practice, the air guide 400 does not completely cover the upper side of the air outlet 131.

[0073] In this way, the guide member 400 does not completely block the upper side of the air outlet 131, and the airflow in the air outlet 131 can flow out of the air outlet 131 through the left and right sides of the guide member 400, and then flow to the upper area of ​​the heat exchanger 300 and the left and right sides of the air outlet 131.

[0074] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6 In a specific implementation, the fan housing 100 includes a partition 110 and at least one housing portion 120, with the fan 200 correspondingly disposed within the housing portion 120, and the partition 110 having at least one flow hole 111.

[0075] The shell portion 120 is correspondingly inserted into the flow passage 111 and connected to the periphery of the corresponding flow passage 111. The shell portion 120 has an air supply channel 130, and the guide member 400 is disposed on the inner wall of the shell portion 120; or, one side of the shell portion 120 is correspondingly connected to the periphery of the flow passage 111, and the interior of the shell portion 120 communicates with the flow passage 111 to jointly form the air supply channel 130, and the guide member 400 is disposed on the hole wall of the flow passage 111.

[0076] The shell portion 120 is provided with a one-to-one correspondence with the flow hole 111.

[0077] In some examples, the flow passage 111 matches a portion of the shell 120, which passes through the flow passage 111 and is connected to the periphery of the flow passage 111 to fix the shell 120 to the partition 110. The shell 120 has an air supply passage 130, and the side of the air supply passage 130 near the heat exchanger 300 has an air outlet 131.

[0078] Furthermore, the shell portion 120 has at least two first connecting portions 121, and the partition portion 110 has at least two second connecting portions 112 corresponding to the first connecting portions 121, with the first connecting portions 121 and the second connecting portions 112 being connected accordingly.

[0079] For example, one of the first connecting portion 121 and the second connecting portion 112 is a hook, and the other is a locking hole that matches the hook. In this application, the first connecting portion 121 is a hook, and the second connecting portion 112 is a locking hole. There are two first connecting portions 121, and the two first connecting portions 121 are located on opposite sides of the housing portion 120.

[0080] It is understandable that the first connecting part 121 and the second connecting part 112 can also be connected by threads.

[0081] In other examples, the shell portion 120 is located on the side of the partition portion 110 away from the heat exchanger 300, and the periphery of the shell portion 120 is correspondingly connected to the periphery of the flow passage 111, so that the interior of the shell portion 120 communicates with the flow passage 111. The flow passage 111 forms an air outlet 131.

[0082] For example, the flow passage 111 can be rectangular. The flow guide 400 can be disposed in the middle region of the upper sidewall of the flow passage 111.

[0083] Reference Figure 2 , Figure 5 and Figure 6 In some embodiments, there are at least two air supply channels 130, and each air supply channel 130 is arranged sequentially at intervals along a preset direction. There are at least two flow guides 400, and each flow guide 400 is correspondingly arranged in each air supply channel 130.

[0084] The flow holes 111 are arranged at intervals along a preset direction, and the shell portions 120 are also arranged at intervals along a preset direction. Specifically, the preset direction is... Figure 2 The direction indicated by the middle arrow and Figure 5 The direction indicated by the middle arrow. The spacing between two adjacent flow holes 111 can be the same or different, and can be adapted to actual needs.

[0085] For example, there are at least two air guides 400, and each air guide 400 is arranged in a corresponding manner within each air supply channel 130. Alternatively, at least two air guides 400 may also be arranged within each air supply channel 130.

[0086] Reference Figure 1 , Figure 2 and Figure 3 Based on the above embodiments, this application provides an air conditioner, including a housing 500 and any of the above-mentioned fan coil structures located within the housing 500.

[0087] The specific structure of the fan coil unit has been described in detail in the above embodiments, and will not be repeated here.

[0088] An air conditioner includes an indoor unit and an outdoor unit, which are connected by pipes. The indoor unit includes a casing 500, and a fan coil unit is located inside the casing 500.

[0089] Specifically, the housing 500 has a receiving cavity, and the fan coil structure is located within the receiving cavity. The partition 110 of the fan housing 100 is connected to the housing 500 to divide the receiving cavity into an air supply cavity and a heat exchange cavity. The flow hole 111 on the partition 110 connects the air supply cavity and the heat exchange cavity. The shell portion 120 of the fan housing 100 is located within the air supply cavity, and the heat exchange element 300 is located within the heat exchange cavity.

[0090] The housing 500 has an air inlet and an air outlet 510. The air inlet is connected to the air supply chamber, and the air outlet 510 is connected to the heat exchange chamber. The fan 200 draws outside air into the air supply chamber through the air inlet, and then sends the outside air to the heat exchange chamber through the air supply channel 130, so that the outside air exchanges heat with the heat exchange element 300. Finally, the outside air is sent out through the air outlet 510.

[0091] The indoor unit of the air conditioner also includes a water tray 600, which is located inside the heat exchange chamber and connected to the housing 500. The water tray 600 is located below the heat exchange element 300 and is used to collect condensate or defrost water on the heat exchange element 300.

[0092] The air conditioner provided in this application embodiment uses a fan 200 with a fan coil structure to drive airflow within the air supply channel 130 towards a first region on the heat exchanger 300. A guide 400 guides a portion of the airflow within the air supply channel 130 towards a second region on the heat exchanger 300. A portion of the second region is located within the first region, while the remaining portion is located outside the first region. The airflow velocity within the first region is greater than the airflow velocity outside the first region. Therefore, the guide 400 can guide a portion of the airflow within the air supply channel 130 towards a region on the heat exchanger 300 with a lower airflow velocity, increasing the velocity of the region on the heat exchanger 300 and thus improving the uniformity of the airflow velocity on the heat exchanger 300, thereby increasing the heat exchange efficiency of the heat exchanger 300.
