Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a heat exchange component. Background Technology

[0002] Floor-standing air conditioners (also known 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] The heat exchange component is one of the important components in a cabinet air conditioner. The heat exchange component generally includes a heat exchanger bracket, a heat exchanger, and an electric heater. In related technologies, the number of electric heaters in the heat exchange component of an air conditioner is fixed, resulting in poor versatility. Utility Model Content

[0004] The purpose of this invention is to provide a heat exchange component that can be equipped with different numbers of electric heaters as needed, thereby improving the versatility of the heat exchange component.

[0005] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides a heat exchange component, comprising: Heat exchanger bracket, on which the heat exchanger is mounted; An electric heating bracket is installed on a heat exchanger bracket. The electric heating bracket has multiple mounting positions, each for detachably mounting an electric heater, which is located on one side of the heat exchanger in the thickness direction.

[0006] With the above settings, different numbers of electric heaters can be installed according to actual needs, thereby adapting to air conditioning indoor units with different air volume levels or heating requirements, and improving the versatility of heat exchange components.

[0007] In an optional embodiment, the electric heating bracket includes a first bracket and a second bracket spaced apart along the height direction. The first bracket and the second bracket are respectively connected to the upper and lower sides of the heat exchanger bracket. The first bracket is provided with a plurality of first mounting parts, and the second bracket is provided with a plurality of second mounting parts. The plurality of first mounting parts and the plurality of second mounting parts correspond one-to-one. The two ends of the electric heating are respectively connected to the first mounting parts and the second mounting parts. The corresponding first mounting parts and the second mounting parts together define a mounting position.

[0008] With the above configuration, the two ends of the electric heater along the height direction can be connected to the first mounting part on the first bracket and the second mounting part on the second bracket, respectively, thereby improving the assembly stability of the electric heater.

[0009] In an optional embodiment, the two ends of the electric heating element are respectively inserted into the first mounting part and the second mounting part. Both the first mounting part and the second mounting part are provided with connection holes. The first mounting part and the second mounting part are connected to the electric heating element after passing through the connection holes via threaded connectors.

[0010] With the above settings, the threaded connection between the electric heater and the electric heater bracket can ensure the stability of the connection between the electric heater and the electric heater bracket, and also facilitate personnel to disassemble and assemble the electric heater.

[0011] In an optional embodiment, the heat exchanger bracket includes a water receiving pan, an upper bracket, and a support frame. The two ends of the support frame are respectively connected to the water receiving pan and the upper bracket, and the two ends of the electric heating bracket are detachably connected to the upper bracket and the water receiving pan.

[0012] The above setup facilitates the disassembly and assembly of the electric heating bracket. If the electric heating bracket is damaged, only the electric heating bracket needs to be replaced, without having to replace the evaporator bracket as well.

[0013] In an optional embodiment, the water receiving tray is provided with a mounting column, which includes a first enclosure plate, a second enclosure plate, a third enclosure plate, and a fourth enclosure plate connected end to end in sequence. The second enclosure plate and the fourth enclosure plate are arranged opposite each other and inclined toward the fourth enclosure plate. The second enclosure plate has a mounting hole. A mating column is provided on the lower side of the electric heating bracket. The mating column is inserted into the mounting column. The mating column includes a mating plate that abuts against the second enclosure plate. The mating plate has a mating hole corresponding to the mounting hole. The heat exchange assembly also includes a threaded fastener. The threaded fastener passes through the mating hole and the mounting hole to make the mounting column and the mating column threadedly connected.

[0014] With the above configuration, due to the inclined setting of the second enclosure plate and the abutment between the mating plate and the second enclosure plate, the threaded fasteners need to be inclined as well. This reduces the space occupied by the connection structure between the water tray and the first bracket in the water tray, and also prevents the mating column and the mounting column from easily separating.

[0015] In an optional embodiment, the mating column further includes a first side plate and a third side plate that are spaced apart and opposite to each other. The two sides of the mating plate are connected to the first side plate and the third side plate respectively. The first side plate, the third side plate and the mating plate together define an insertion groove. The insertion groove is inserted into the mounting column. The first side plate is opposite to the first enclosure plate, the third side plate is opposite to the third enclosure plate, and the mating plate overlaps the second enclosure plate.

[0016] With the above configuration, the second enclosure plate serves to support the mating plate and improve the stability of the connection between the first bracket and the water receiving tray.

[0017] In an optional embodiment, the first support includes a first frame and a second frame connected at an angle, and the second support includes a third frame and a fourth frame connected at an angle. The first frame and the third frame are opposite each other in the height direction, and the second frame and the fourth frame are opposite each other in the height direction. The heat exchanger includes a first heat exchange section and a second heat exchange section connected at an angle, a first frame and a third frame are parallel to the first heat exchange section, and a second frame and a fourth frame are parallel to the second heat exchange section. And / or, a first mounting part is provided at the connection between the first frame and the second frame, a plurality of first mounting parts are provided on the side of the first frame away from the second frame, and a plurality of first mounting parts are provided on the side of the second frame away from the first frame.

[0018] With the above settings, the first and second supports can be roughly parallel to the heat exchanger, thereby ensuring that the airflow passing through the evaporator is heated relatively evenly by the electric heating; different numbers of electric heaters can be set on both sides of the electric heating support as needed.

[0019] In an optional embodiment, the heat exchanger support includes a water receiving tray, an upper support, and a support frame. The two ends of the support frame are respectively connected to the water receiving tray and the upper support, and the first support and the second support are respectively connected to the water receiving tray and the upper support. The height of the first support is lower than the height of the side wall of the water receiving pan; and / or, the first support is provided with ventilation holes that penetrate the first support along the arrangement direction of the heat exchanger and the electric heater.

[0020] The above settings can reduce the impact of the first bracket on the airflow passing through the heat exchanger, thus ensuring the airflow effect of the indoor unit of the air conditioner.

[0021] In an optional embodiment, the first bracket is provided with a wire harness structure on both sides of its extension direction; And / or, the first support has a wire harness structure at the middle of its extension direction.

[0022] The above settings ensure the stability of the electric heating wiring on the electric heating bracket.

[0023] In an optional implementation, the cable harness structure includes a cable tray, a wire clamp, or a cable tie.

[0024] The beneficial effects provided by this embodiment of the utility model include: A heat exchange component provided by this embodiment of the utility model includes a heat exchanger bracket and an electric heating bracket. A heat exchanger is mounted on the heat exchanger bracket, and the electric heating bracket is mounted on the heat exchanger bracket. The electric heating bracket has multiple mounting positions, each for detachably mounting an electric heater, which is located on one side of the heat exchanger in the thickness direction. Because the electric heating bracket in this embodiment has multiple mounting positions, different numbers of electric heaters can be installed according to actual needs, thereby adapting to air conditioning indoor units with different airflow levels or heating requirements, improving the versatility of the heat exchange component.

[0032] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0033] 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.

[0034] The following describes in detail, with reference to the accompanying drawings, the specific structure of a heat exchange component provided by this utility model and its corresponding technical effects.

[0035] It should be noted that the heat exchange component provided in this embodiment of the present invention is applied to the indoor unit of an air conditioner. The air conditioner can be a cabinet unit, such as a square cabinet or a round cabinet. In this embodiment, the heat exchange component is applied to the indoor unit of a square cabinet air conditioner.

[0036] Please refer to Figures 1-3 The present invention provides a heat exchange assembly 1 including a heat exchanger bracket 100 and an electric heating bracket 300. A heat exchanger 200 is mounted on the heat exchanger bracket 100, and the electric heating bracket 300 is mounted on the heat exchanger bracket 100. The electric heating bracket 300 is provided with a plurality of mounting positions 301, each mounting position 301 for detachably mounting an electric heater 400, the electric heater 400 being located on one side in the thickness direction of the heat exchanger 200.

[0037] It should be noted that "multiple" in this embodiment can be understood as two or more quantities.

[0038] Understandably, when the heat exchange component 1 is applied in the indoor unit of an air conditioner, the electric heater 400 is located on the side of the heat exchanger 200 near the air outlet of the indoor unit.

[0039] Understandably, since the electric heating bracket 300 in this embodiment is provided with multiple mounting positions 301, different numbers of electric heaters 400 can be installed according to actual needs, thereby adapting to air conditioning indoor units with different air volume levels or heating requirements, and improving the versatility of the heat exchange component 1.

[0040] Moreover, it is not necessary to develop a separate heat exchanger bracket 100 or a complete heat exchange assembly 1 for each power requirement, thereby reducing mold investment and inventory management costs.

[0041] In detail, the electric heating bracket 300 includes a first bracket 310 and a second bracket 320 spaced apart along the height direction. The first bracket 310 and the second bracket are respectively connected to the upper and lower sides of the heat exchanger bracket 100. The first bracket 310 is provided with a plurality of first mounting parts 3140, and the second bracket 320 is provided with a plurality of second mounting parts 3210. The plurality of first mounting parts 3140 and the plurality of second mounting parts 3210 correspond one-to-one. The two ends of the electric heater 400 are respectively connected to the first mounting parts 3140 and the second mounting parts 3210. The corresponding first mounting parts 3140 and the second mounting parts 3210 together define a mounting position 301.

[0042] In other words, the two ends of the electric heater 400 along the height direction can be connected to the first mounting part 3140 on the first bracket 310 and the second mounting part 3210 on the second bracket 320, respectively, thereby improving the assembly stability of the electric heater 400.

[0043] Specifically, in this embodiment, the heat exchanger 200 includes a first heat exchange section and a second heat exchange section connected at an angle, the first support 310 includes a first frame 311 and a second frame 312 connected at an angle, and the second support 320 includes a third frame 321 and a fourth frame 322 connected at an angle. The first frame 311 and the third frame 321 are opposite each other in the height direction, and the second frame 312 and the fourth frame 322 are opposite each other in the height direction. The first frame 311 and the third frame 321 are parallel to the first heat exchange section, and the second frame 312 and the fourth frame 322 are parallel to the second heat exchange section.

[0044] It should be noted that the parallelism in this embodiment is not limited to parallelism in a strict sense; it is sufficient as long as the two are approximately perpendicular.

[0045] Understandably, the first support 310 and the second support 320 are roughly parallel to the heat exchanger 200, which can ensure that the airflow passing through the evaporator is heated relatively evenly by the electric heater 400.

[0046] Since the first frame 311 and the second frame 312 of the first support 310 are parallel to the first heat exchange section and the second heat exchange section respectively, and the third frame 321 and the fourth frame 322 of the second support 320 are parallel to the first heat exchange section and the second heat exchange section respectively, interference between the first support 310 and the second support and the evaporator can be avoided.

[0047] In detail, the first heat exchange section and the second heat exchange section are connected by an arc transition. Optionally, the first frame 311 and the second frame 312 can be connected by an arc transition, and the third frame 321 and the fourth frame 322 can also be connected by an arc transition. While reducing the stress concentration between the first frame 311 and the second frame 312 and between the third frame 321 and the fourth frame 322, it can also ensure that the distance between the electric heater 400 on the first support 310 and the second support 320 and the evaporator is relatively uniform.

[0048] Specifically, in this embodiment, a first mounting portion 3140 is provided at the connection between the first frame 311 and the second frame 312. Multiple first mounting portions 3140 are provided on the side of the first frame 311 away from the second frame 312, and multiple first mounting portions 3140 are provided on the side of the second frame 312 away from the first frame 311. Since the multiple second mounting portions 3210 on the second bracket 320 correspond one-to-one with the multiple first mounting portions 3140 on the first bracket 310, a second mounting portion 3210 is provided at the connection between the third frame 321 and the fourth frame 322. Multiple first mounting portions 3140 are provided on the side of the third frame 321 away from the fourth frame 322, and multiple first mounting portions 3140 are provided on the side of the fourth frame 322 away from the third frame 321.

[0049] In some embodiments, three first mounting portions 3140 are provided on the side of the first frame 311 away from the second frame 312, and three first mounting portions 3140 are also provided on the side of the second frame 312 away from the first frame 311. That is, a maximum of seven electric heaters 400 can be mounted on the electric heating bracket 300.

[0050] Of course, in other embodiments, the number of first mounting portions 3140 on the first bracket 310 and the number of second mounting portions 3210 on the second bracket 320 may be other numbers.

[0051] In this embodiment, the two ends of the electric heating 400 are respectively inserted into the first mounting part 3140 and the second mounting part 3210. Both the first mounting part 3140 and the second mounting part 3210 are provided with connecting holes. The first mounting part 3140 and the second mounting part 3210 are connected to the electric heating 400 after passing through the connecting holes by threaded connectors.

[0052] This ensures the stability of the connection between the electric heater 400 and the electric heater bracket 300, and also facilitates the disassembly and assembly of the electric heater 400.

[0053] Of course, in some other embodiments, the two ends of the electric heating 400 can be respectively engaged with the first mounting part 3140 and the second mounting part 3210.

[0054] In this embodiment, the first support 310 is an integral structure formed by the first frame 311 and the second frame 312, and the second support 320 can also be an integral structure formed by the third frame 321 and the fourth frame 322. This ensures the structural strength of the electric heating support 300.

[0055] In this embodiment, the heat exchanger bracket 100 includes a water receiving tray 110, an upper bracket 130, and a support frame 120. Both ends of the support frame 120 are connected to the upper bracket 130 and the water receiving tray 110, respectively. The electric heating bracket 300 is detachably connected to both the upper bracket 130 and the water receiving tray 110, facilitating the assembly and disassembly of the electric heating bracket 300. Specifically, the first bracket 310 is detachably connected to the water receiving tray 110, and the second bracket 320 is detachably connected to the upper bracket 130.

[0056] In detail, the water receiving tray 110 is provided with a mounting post 1100. The mounting post 1100 includes a first enclosure plate 111, a second enclosure plate 112, a third enclosure plate 113, and a fourth enclosure plate 114 connected end to end in sequence. The second enclosure plate 112 and the fourth enclosure plate 114 are arranged opposite each other and are inclined toward the fourth enclosure plate 114. The second enclosure plate 112 has a mounting hole 1121. The lower side of the electric heating bracket 300 is provided with a mating post. The mating post is inserted into the mounting post 1100. The mating post includes a mating plate 3120 that abuts against the second enclosure plate 112. The mating plate 3120 has a mating hole 3121 corresponding to the mounting hole 1121. The heat exchange assembly 1 includes a threaded fastener. The threaded fastener passes through the mating hole 3121 and the mounting hole 1121 to make the mounting post 1100 threadedly connected to the mating post.

[0057] Understandably, since the second enclosure plate 112 is inclined and the mating plate 3120 abuts against the second enclosure plate 112 (meaning the mating plate 3120 is also inclined and parallel to the second enclosure plate 112), the threaded fastener needs to be inclined to pass through the mounting hole 1121 and the mating hole 3121 to lock the mounting post 1100 and the mating post. It should be noted that one of the mounting hole 1121 and the mating hole 3121 is a threaded hole. This design reduces the space occupied by the connection structure between the water tray 110 and the first bracket 310 in the water tray 110, and also prevents the mating post and the mounting post 1100 from easily separating.

[0058] Specifically, the mating column also includes a first side plate 3110 and a third side plate 3130 spaced apart and opposite to each other. The two sides of the mating plate 3120 are connected to the first side plate 3110 and the third side plate 3130 respectively. The first side plate 3110, the third side plate 3130, and the mating plate 3120 together define an insertion groove, which is inserted into the mounting column 1100. The first side plate 3110 is opposite to the first surrounding plate 111, and the third side plate 3130 is opposite to the third surrounding plate 113. The mating plate 3120 overlaps the second surrounding plate 112. That is, the second surrounding plate 112 serves to support the mating plate 3120.

[0059] Optionally, in some embodiments, the height of the first bracket 310 is lower than the height of the side wall of the water receiving tray 110. This arrangement can reduce the impact of the first bracket 310 on the airflow passing through the heat exchanger 200, thus ensuring the airflow effect of the indoor unit of the air conditioner.

[0060] Alternatively, in some other embodiments, in order to reduce the obstruction of the first support 310 to the air passing through the heat exchanger 200, the first support 310 is provided with ventilation holes (not shown), which penetrate the first support 310 along the arrangement direction of the heat exchanger 200 and the electric heater 400.

[0061] Optionally, to facilitate the stability of the wiring of the electric heater 400 on the electric heating bracket 300, in some embodiments, the first bracket 310 is provided with a wire harness structure on both sides of its extension direction (not shown in the figure). That is, both the first bracket 311 and the second bracket 312 can be provided with a wire harness structure. The first bracket 310 is also provided with a wire harness structure in the middle of its extension direction. In other words, a wire harness structure can also be provided at the connection between the first bracket 311 and the second bracket 312.

[0062] The aforementioned wiring structure includes cable trays, wire clamps, or cable ties. It is understood that since both the first frame 311 and the second frame 312 are equipped with wiring structures, the wiring harness (not shown) of the electric heating 400 installed on the first frame 311 or the second frame 312 can be routed upwards from the wiring structure of the first frame 311 or the second frame 312, passing through the wiring structure at the connection point of the first frame 311 and the second frame 312. This ensures the stability of the electric heating 400 wiring harness routing.

[0063] In summary, the heat exchange assembly 1 provided in this embodiment includes a heat exchanger bracket 100 and an electric heating bracket 300. A heat exchanger 200 is mounted on the heat exchanger bracket 100, and the electric heating bracket 300 is mounted on the heat exchanger bracket 100. The electric heating bracket 300 has multiple mounting positions 301, each for detachably mounting an electric heater 400, which is located on one side of the heat exchanger 200 in the thickness direction. Because the electric heating bracket 300 in this embodiment has multiple mounting positions 301, different numbers of electric heaters 400 can be installed according to actual needs, thereby adapting to air conditioning indoor units with different airflow levels or heating requirements, improving the versatility of the heat exchange assembly 1.

[0064] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
