Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] Example 1: As Figures 1-4 ,include:

[0029] A coil housing 100 has a partition 110 fixedly installed on one inner wall of the coil housing 100, and a first air inlet 111 is provided on the inner wall of the partition 110.

[0030] Fan coil unit 300 is S-shaped and has four layers. Adjacent fan coil units 300 are connected by arc-shaped pipes.

[0031] The fan assembly includes a dual-axis servo motor 230, and the output shafts on both sides of the dual-axis servo motor 230 are fixedly connected to the impeller 240.

[0032] The specific application scenario of this embodiment is as follows: When the dual-axis servo motor 230 starts, the two side impellers 240 rotate synchronously, drawing in cabin air through the first air inlet 111 on the partition 110. After entering the coil housing 100, the air flows through the four layers of S-shaped fan coil units 300, exchanging heat with the water circulating inside the coils to achieve air cooling or heating. The treated air is then discharged through the other side of the coil housing 100, completing the cabin air conditioning. The dual-axis drive design improves airflow and energy efficiency ratio, while the S-shaped coils enhance the heat exchange effect by increasing the heat exchange area.

[0033] Example 2: Figure 3 and Figure 4The partition 110 is recessed and fixedly installed on the inner wall of the coil housing 100. Two sets of air inlets 111 are symmetrically arranged on the left and right sides. The coil housing 100 is flat. An air outlet plate 120 is fixedly installed on the outer wall of the coil housing 100 away from the partition 110. An air outlet is opened on the surface of the air outlet plate 120.

[0034] The specific application scenario of this embodiment is as follows: The concave baffle 110 and the flat coil housing 100 form a symmetrical airflow channel. The two sets of first air inlets 111 on the left and right sides draw in air evenly, reducing turbulence loss. The drawn-in air forms a laminar flow under the guidance of the baffle and is discharged through the air outlet 120 on the other side of the coil housing 100. The flat structure shortens the airflow path, reduces wind resistance, and saves installation space, making it suitable for use in narrow areas of ships.

[0035] Example 3: Figures 3-5 The fan assembly includes a mounting plate 200, which is embedded and fixedly mounted on the outer wall of a partition 110. A second air inlet 210 is opened on the inner wall of the mounting plate 200, and the second air inlet 210 is correspondingly connected to the first air inlet 111. A fan shroud 220 is fixedly mounted on the inner walls of the second air inlet 210 and the first air inlet 111. The output end of the fan shroud 220 is inserted into the interior of the first air inlet 111 and the second air inlet 210. A filter screen 250 is fixedly mounted on the inner wall of the output end of the fan shroud 220. A dual-axis servo motor 230 is fixedly mounted on the outer wall of the mounting plate 200. The two output shafts of the dual-axis servo motor 230 are fixedly connected to a drive shaft 231 through flanges. A fan wheel 240 is fixedly mounted on the outer wall of the drive shaft 231. The blades of the fan wheel 240 are arc-shaped and the fan wheel 240 is located inside the fan shroud 220. A side plate 221 is detachably and fixedly mounted on the outer wall of the fan shroud 220 away from the dual-axis servo motor 230.

[0036] The specific application scenario of this embodiment is as follows: Air enters the mounting plate 200 through the first air inlet 111 and the second air inlet 210, and is accelerated by the impeller 240 driven by the dual-axis servo motor 230 after being gathered by the fan shroud 220. The filter screen 250 in the fan shroud 220 intercepts dust and water vapor to prevent the coil from clogging. When the high-speed airflow passes through the four-layer S-shaped fan coil 300, it exchanges heat with the refrigerant. The arc-shaped impeller blades increase the air pressure to ensure uniform air distribution. The detachable side plate 221 facilitates the maintenance of the filter screen. The flange connection design between the drive shaft 231 and the impeller 240 simplifies the maintenance process.

[0037] Example 4: Figure 5 and Figure 6 The inner diameter of the fan coil unit 300 is 10 mm, the spacing between adjacent fan coil units 300 is 50 mm, the outer wall of the fan coil unit 300 is uniformly fixed with fins 310, the bottom end of the fan coil unit 300 is the water inlet end 320, and the top end of the fan coil unit 300 is the water outlet end 330.

[0038] The specific application scenario of this embodiment is as follows: Low-temperature or high-temperature refrigerant flows in from the water inlet 320 at the bottom of the fan coil 300, flows in the S-shaped coil with a diameter of 10mm, exchanges heat with the air, and is discharged from the water outlet 330 at the top. The fins 310 outside the coil enhance air turbulence. With the 50mm tube spacing design, the heat exchange efficiency per unit volume is improved. When the air flows through the coil, the temperature is regulated, and efficient heat exchange is achieved in a compact space, which is suitable for high-load areas of ships.

[0039] The working principle of this utility model is as follows: When used by those skilled in the art, the dual-axis servo motor 230 is started, driving the two side impellers 240 to rotate. Air is drawn into the chamber through the first air inlet 111 on the partition 110 and the second air inlet 210 on the inner wall of the mounting plate 200. The air is gathered by the fan shroud 220, and the filter screen 250 on the inner wall of the output end of the fan shroud 220 intercepts dust and moisture to prevent the coil from clogging. The accelerated air enters the coil housing 100. The inner diameter of the fan coil 300 is 10 mm. The fan coil unit 300 has a 50 mm spacing between adjacent coils. The fins 310 evenly installed on its outer wall enhance air turbulence. Low-temperature or high-temperature refrigerant flows in from the water inlet 320 at the bottom of the fan coil unit 300, exchanges heat with the air, and is discharged from the water outlet 330 at the top, thereby achieving air cooling or heating. The treated air is discharged through the air outlet 120 installed on the outer wall of the coil housing 100 away from the partition 110. The air outlet of the air outlet 120 can be adjusted to meet different air supply needs.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
