[0002] Currently, the heat exchangers and condensers of fan coil units sold on the market have a fixed structure, thus their cooling capacity is limited by the capacity of the heat exchangers and condensers. For users, this means a relatively small range of cooling adjustment; for example, the common range of speed settings is 5 to 9, and the upper and lower limits of the unit's cooling are low. Even if there are many speed settings, they are densely spaced, and there is no actual experience of a large change in cooling capacity.

[0003] However, in daily use, a wide range of cooling settings is highly beneficial to the user experience. Therefore, the existing structure of fan coil units limits their effectiveness.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] According to an embodiment of the present invention, a coil structure is provided; please refer to [link / reference]. Figures 1 to 7 The fan coil unit structure of this embodiment includes: heat dissipation fins 1, with multiple connection holes 11 on the fins 1; multiple heat dissipation pipes 2, each corresponding to one of the connection holes 11, with each heat dissipation pipe 2 passing through the corresponding connection hole 11; the multiple heat dissipation pipes 2 for circulating refrigerant; and a driving device 3 connected to the heat dissipation fins 1 to drive the fins 1 to move, thereby changing the relative position between at least two connection holes 11. With the above configuration, by moving the heat dissipation fins 1 and changing their shape, the fan coil unit can achieve bending transformation of the two-phase structure, thus allowing for adjustment of the unit's cooling capacity. Therefore, when the user needs a greater cooling effect, the bending angle of the two-phase structure can be immediately changed, resulting in a wider range of cooling capacity adjustment. This fan coil unit not only benefits the user experience but also saves on purchase costs, serving as a multi-unit solution and solving the technical problem of low heat dissipation efficiency in existing fan coil units.

[0032] In the coil structure of this embodiment, the coil structure also includes two side plates 4 arranged at intervals, and multiple heat dissipation fins 1 are provided, all of which are located between the two side plates 4 and are arranged at intervals; the driving device 3 is provided on the side plates 4.

[0033] Specifically, in some embodiments, the driving device 3 moves on the side plate 4, thereby driving the heat dissipation fins 1 to move; in other embodiments, the side plate 4 moves under the drive of the driving device 3, thereby driving the heat dissipation fins 1 to move.

[0034] See Figures 3 to 5In the coil structure of this embodiment, the side plate 4 includes a first plate 41 and a second plate 42, which are movably arranged relative to each other. The driving device 3 includes: a drive motor with a drive rod 31 on its output shaft to drive the drive rod 31 to rotate; a first drive part 44 and a second drive part 45, which are respectively arranged at opposite ends of the drive rod 31; the first drive part 44 is connected to the first plate 41, and the second drive part 45 is connected to the second plate 42. In this way, by driving the relative movement between the first plate 41 and the second plate 42, the heat dissipation fins 1 are driven to move, thereby realizing the bendability of the two devices.

[0035] In the coil structure of this embodiment, the heat dissipation fins 1 include a first fin portion connected to the first driving part 44 and a second fin portion connected to the second driving part, and the first fin portion and the second fin portion are rotatably connected relative to each other. In this way, by driving the relative rotation between the first plate 41 and the second plate 42, the heat dissipation fins 1 are driven to rotate, thereby realizing the bendability of the two devices.

[0036] The control method of this embodiment is applicable to the above-mentioned coil structure. The control method includes: detecting the cooling capacity demand of the unit; and controlling the drive device 3 to drive the heat dissipation fins 1 to move according to the cooling capacity demand of the unit, so as to change the heat exchange efficiency of the coil structure.

[0037] The control method of this embodiment includes: driving the heat dissipation fins 1 to bend via the driving device 3; setting several bending angles, and driving the heat dissipation fins 1 to bend at corresponding angles according to the cooling capacity requirements of the unit, thereby changing the heat exchange efficiency of the coil structure; setting a compensation angle; comparing with the quality requirements of the unit to determine whether it is necessary to improve the heat exchange efficiency of the coil structure, and if so, driving the heat dissipation fins 1 to bend at an integer multiple of the compensation angle.

[0038] To achieve smooth movement of the heat dissipation fins 1, in the coil structure of this embodiment, see... Figures 3 to 5 The first plate 41 is provided with a first guide rail 411, and the first guide rail 411 is provided with a first gear tooth. The first drive unit 44 includes a first gear 441 that meshes with the first gear tooth. The second plate 42 is provided with a second guide rail 421, and the second guide rail 421 is provided with a second gear tooth. The second drive unit 45 includes a second gear 451 that meshes with the first gear tooth.

[0039] See Figure 6In the coil structure of this embodiment, there are two first gears 441, each corresponding to one of the two side plates 4. There are also two second gears 451, each corresponding to one of the two side plates 4. The first drive unit 44 includes a first connecting rod 442, one end of which is connected to one of the first gears 441, and the other end of which is connected to the other first gear 441. The first connecting rod 442 passes through the heat dissipation fins 1. The second drive unit 45 includes a second connecting rod 452, one end of which is connected to one of the second gears 451, and the other end of which is connected to the other second gear 451. The second connecting rod 452 also passes through the heat dissipation fins 1. This allows multiple heat dissipation fins 1 to bend together, causing overall deformation of the two heat exchangers and thus adjusting their heat exchange efficiency.

[0040] In the coil structure of this embodiment, the first guide rail portion 411 forms a closed first guide groove 412, and the first gear teeth are disposed on the two opposite side walls of the first guide groove 412; the second guide rail portion 421 forms a closed second guide groove 422, and the second gear teeth are disposed on the two opposite side walls of the second guide groove 422. This ensures that the drive device 3 will not derail when the two components frequently change shape, allowing the equipment to operate smoothly.

[0041] In the coil structure of this embodiment, the coil structure also includes a manifold 5, which is located on the side of the side plate 4 away from the heat dissipation fins 1. The manifold 5 is connected to multiple heat dissipation pipes 2, and the manifold 5 is a flexible tube. In this way, no matter how the shape of the two devices changes, it will not affect the connection between the external connecting pipes and the heat dissipation pipes 2.

[0042] In the coil structure of this embodiment, the heat dissipation fins 1 include a plurality of connecting parts 12, which are connected in sequence, and two adjacent connecting parts 12 are rotatably connected to each other.

[0043] In the coil structure of this embodiment, the connecting part 12 includes: a heat dissipation part 121, and a connecting hole 11 is provided on the heat dissipation part 121; two rotating parts 122 are provided at intervals, and the two rotating parts 122 are respectively provided at opposite ends of the heat dissipation part 121; the rotating part 122 on one of the two adjacent connecting parts 12 is rotatably connected to the rotating part 122 on the other of the two adjacent connecting parts 12.

[0044] The heat dissipation part 121 is provided with a plurality of connection holes 11, which are arranged at intervals along the extension direction of the heat dissipation part 121.

[0045] The coil structure of this embodiment is described as follows:

[0046] The coil structure in this embodiment consists of a side plate 4 with gear teeth, movable heat dissipation fins 4, and a drive device 3. The movable heat dissipation fins 4 are located between two side plates 4 with gear teeth, evenly spaced at 1.2mm intervals. The drive device 3 is located on the side plate 4 with gear teeth, and the rotatable portion of the movable heat dissipation fins 4 is controlled by the drive device 3. The drive device 3 consists of a stepper motor, gears, and their matching shafts. The gears engage with the gear teeth on the side plate 4, driving the movable heat dissipation fins 4 to rotate and bend. The movable heat dissipation fins 4 are equipped with heat dissipation pipes 2, specifically copper pipes. The copper pipes are fitted with flexible hoses for water distribution, and the flexible hoses are fitted onto the copper pipes and secured with iron plates welded together in a ring. When the heat dissipation fins 4 are bent, the water distribution head of the flexible hoses can change accordingly without damage.

[0047] Figure 8 The diagram below illustrates the control system for this type of fan coil unit. Based on the aforementioned fan coil unit structure, the movable heat dissipation fins 4 are controlled for rotational bending. The specific workflow is as follows: The unit starts, and the bending settings for both heat exchangers are executed. There are five bending angles in total. Bending angles 1 and 5 are initially set to 90 degrees by default, while bending angles 2, 3, and 4 are set to 180 degrees by default. The desired cooling capacity is input, and the unit is then turned on. When the upper limit of cooling capacity meets the target value, the upper limit is divided into five equal increments, and the unit operates accordingly. If the target cooling capacity is not met, the bending angles are adjusted. The adjustment range for bending angles 1 and 5 is 45 degrees to 90 degrees; the bending range for bending angles 2, 3, and 4 is 135 degrees to 180 degrees. Each adjustment step is 15 degrees, allowing for different step adjustments to be set for different bending angles until the desired cooling capacity is achieved. The upper limit is then divided into five equal increments.
