Description

Technical Field

[0001] The present application relates to the field of ship technology, and in particular to a ventilator device. Background Art

[0002] With the rapid development of marine engineering technology, the comfort and safety of ship interiors are receiving increasing attention. In the field of ship ventilation systems, ventilation accessories are key components for ensuring cabin air quality and maintaining cabin pressure balance. Their performance directly impacts the overall operating efficiency of the ship and the crew's work and life quality.

[0003] Ventilation accessories have exposed many problems that need to be solved in actual application. First, existing ventilation accessories are generally not equipped with a preheating function in the air conditioning fresh air processing link. In cold climate conditions, the fresh air that has not been preheated directly enters the cabin, which will cause the indoor temperature to drop sharply and cause the air conditioning system to start and stop frequently, which not only increases energy consumption but also shortens the service life of the equipment. Secondly, the lack of noise reduction function means that during the operation of the ship, external mechanical noise and wind and wave noise can be directly transmitted into the room through the ventilation ducts. At the same time, the noise of the equipment inside the cabin will also be transmitted outward, greatly reducing the comfort of the crew's working and rest environment. Long-term exposure to high-noise environments may even endanger the crew's hearing health. Summary of the Invention

[0023] Figure 1 This is a schematic structural diagram of the ventilation duct device provided in an embodiment of the present application. Figure 2 for Figure 1 Schematic diagram of the AA cross-section structure. Figure 1 and 2 As shown, this embodiment provides a ventilation device, comprising: a cylinder 100, a preheating pipe 200 and a first silencer 300; the first end of the cylinder 100 (such as Figure 1 The upper end of the cylinder 100 shown in FIG. 1 is connected to the outdoor air, and the second end of the cylinder 100 (as shown in FIG. Figure 1The lower end of the cylinder 100 shown in the figure is connected to the air inlet of the air conditioning and ventilation device; the preheating pipeline 200 is arranged in the inner cavity of the cylinder 100 along the contour shape of the inner cavity of the cylinder 100, and the inlet 210 of the preheating pipeline and the outlet 220 of the preheating pipeline are both arranged at the second end of the cylinder 100; the preheating pipeline 200 is filled with a preheating medium; and the first silencer 300 is sleeved on the outside of the cylinder 100.

[0024] It should be further explained here that the first end of the cylinder 100 can refer to Figure 1 The upper end of the cylinder 100 is shown. Generally speaking, the first end of the cylinder 100 is located outdoors and is used to connect to the outdoor environment. It is the initial port for air to enter. The second end of the cylinder 100 can refer to Figure 1 The lower end of the cylinder 100 is shown. Generally speaking, the second end of the cylinder 100 will extend to the indoor space (such as the cabin, the living cabin), and directly communicate with the air inlet of the air conditioning and ventilation device through a flange.

[0025] During operation of the ventilation duct device provided in this embodiment, outdoor air enters from the first end of the cylinder 100 and flows along the inner cavity of the cylinder 100. At this time, the preheating pipe 200 arranged in the inner cavity of the cylinder 100 takes effect. The preheating medium in the preheating pipe 200 is in full contact with the airflow, gradually heating the low-temperature air, and avoiding a sudden drop in the cabin temperature due to the low temperature of the fresh air. The preheated air flows out from the second end of the cylinder 100 and enters the subsequent air conditioning and ventilation system, effectively reducing the load of the air conditioning system and reducing energy loss and equipment loss caused by frequent start-up and shutdown. In this embodiment, the coordinated design of the preheating pipe 200 and the first silencer 300 achieves the dual functions of airflow preheating and noise reduction.

[0026] Regarding the selection of preheating medium, a brief introduction is provided. The preheating medium can be a liquid or gaseous medium, specifically water, ethylene glycol solution, thermal oil, etc. In one embodiment, ethylene glycol solution is used as the preheating medium. Due to its low freezing point and high specific heat capacity, it is better suited to winter operating conditions in cold regions and has high heating efficiency.

[0027] The structure of the first silencer 300 is described in detail below. The first silencer 300 has an annular cylindrical structure formed by a perforated metal plate and the outer wall of the cylinder. The inner cavity of the annular cylindrical structure is filled with a sound-absorbing material, which can be glass fiber wool. In this embodiment, the perforated metal plate not only provides a support frame for the sound-absorbing material, but also allows sound waves to penetrate unimpeded into the interior of the first silencer 300. When high-frequency airflow noise is introduced from the outside, the sound waves can enter the sound-absorbing material (e.g., glass fiber wool) through the holes in the perforated metal plate, where they are absorbed and converted into heat energy within the complex pore structure.

[0028] Furthermore, a damping coating is coated on the surface of the annular cylindrical structure and the sound-absorbing material on one side of the annular cylindrical structure relative to the outer wall of the cylinder. The damping coating can suppress the secondary noise generated by the cylinder due to the airflow vibration, and reduce the solid sound transmission of sound waves through the cylinder, thereby reducing the noise transmission efficiency.

[0029] The shape of the cylinder 100 can be any one of a vertical tube shape, a gooseneck shape, and a mushroom shape. Figure 1 The barrel 100 shown in the figure is in the shape of a vertical tube, but it should be understood that this is not a limitation.

[0030] In one embodiment, the device further includes: a heating element 400 , which is vertically arranged in the barrel 100 and connected to the inner wall of the barrel 100 via a first connecting element 410 .

[0031] In this embodiment, when the outdoor low-temperature air enters from the first end of the cylinder 100, it first contacts the preheating pipeline 200 arranged along the inner cavity contour of the cylinder 100. The preheating medium in the preheating pipeline 200 continuously releases heat to preliminarily heat the airflow, thereby achieving basic preheating. Then, the air continues to flow to the second end of the cylinder 100. At this time, the heating element 400 in the inner cavity of the cylinder 100 begins to intervene and make up for the insufficient heating of the preheating pipeline 200, thereby achieving rapid heating. The dual heating mode provided in this embodiment not only significantly improves the preheating efficiency of the fresh air, but also reduces the long-term high-load operation time of the heating element 400 and reduces energy consumption. At the same time, since the air in the inner cavity of the cylinder 100 is fully heated twice, the temperature uniformity is guaranteed, avoiding the problem of local uneven cold and heat, effectively reducing the operating pressure of the air-conditioning system, extending the service life of the equipment, and providing a more comfortable and stable temperature environment for the ship's cabin.

[0032] In one embodiment, the preheating pipe 200 is arranged around the heating element 400. In this embodiment, the heat of the heating element 400 is first directly transferred to the preheating medium in the preheating pipe 200, and then heat is exchanged with the airflow through the outer wall of the preheating pipe 200. This creates a dual preheating effect of active heating combined with heat storage by the preheating medium, achieving efficient heat conduction and uniform distribution. This not only improves the preheating performance of the ventilator device in cold environments, but also reduces energy consumption through the heat storage characteristics of the preheating medium.

[0033] It should be noted that in this embodiment, the heating element 400 can be arranged along the central axis of the barrel 100, and the preheating pipeline 200 can be wound around the periphery of the heating element in a spiral or annular manner. The preheating pipeline 200 is still arranged in the inner cavity of the barrel 100 in the area outside the heating element along the contour of the inner cavity of the barrel 100. Here, the heating element 400 can release heat by means of resistance heating or steam heat dissipation.

[0034] In one embodiment, the second muffler 500 is further included. The second muffler 500 is arranged outside the heating element 400 and connected to the inner wall of the barrel 100 via a second connecting member 510 .

[0035] As an optional embodiment, a plurality of the second silencers 500 are evenly distributed along the axial direction of the cylinder 100. Figure 1 As shown, in this embodiment, each second silencer 500 has an annular structure. Furthermore, each second silencer 500 includes at least one silencer segment; multiple silencer segments are evenly distributed along the circumference of the cylinder 100, and each silencer segment is connected to the inner wall of the cylinder 100 via a second connecting member 510. Adjacent silencer segments are joined together, forming a ring structure formed by the multiple silencer segments along the circumference.

[0036] As an optional embodiment, multiple second silencers 500 are evenly distributed along the circumference of the barrel 100. In this embodiment, each second silencer 500 has an arcuate strip structure, and multiple second silencers 500 can be circumferentially enclosed to form a ring structure. Furthermore, each second silencer 500 includes at least one silencer segment; multiple silencer segments are evenly distributed along the axial direction of the barrel 100, and each silencer segment is connected to the inner wall of the barrel 100 via a second connecting member 510. Adjacent silencer segments are spliced together.

[0037] Regarding the placement of the second muffler 500, it's important to note that it's located between the heater 400 and the preheating line 200. A gap (which can be 5 to 10 mm) is required between the second muffler 500 and the inner wall of the preheating line 200. A gap (which can be 5 to 8 mm) is also required between the second muffler 500 and the outer wall of the heater 400. This creates an air insulation layer between the second muffler 500 and the inner wall of the preheating line 200, and between the second muffler 500 and the outer wall of the heater 400. This reduces the temperature of the second muffler 500 and extends its service life.

[0038] Regarding the installation of the second muffler 500, in this embodiment, the second connecting member 510 is installed on the inner wall of the cylinder 100. The second connecting member 510 can be a detachable clamp or an elastic buckle. Conversely, the second connecting member 510 can also be fixed to the outer wall of the heating element by a detachable clamp or an elastic buckle, which is not limited here.

[0039] The second silencer 500 can be a sound-absorbing sheet. It comprises, in order from the side facing away from the heater 400 to the side opposite the heater 400, a base layer, a filling layer, and a damping layer. The base layer is a perforated metal plate with a thickness of 1mm to 2mm and a perforation ratio of 30% or higher, ensuring smooth airflow and directing airflow noise into the filling layer. The filling layer is affixed to the base layer and can be made of glass fiber wool (with a density of at least 64kg / m³). This layer enhances mid- and high-frequency sound absorption. A damping layer is applied to the filling layer and can be made of butyl rubber damping material. This damping layer suppresses vibration transmission from the heater. When airflow noise generated by the heater 400 propagates outward, the sound waves penetrate the perforated plate and enter the glass fiber wool. Friction and viscosity within the fiber pores convert the sound energy into heat.

[0040] In one embodiment, the heating element 400 further includes a third muffler 600. The third muffler 600 is mounted on both the upper and lower ends of the heating element 400. The arrangement of the third muffler 600 in this embodiment can be similar to that of the second muffler 500, and is not specifically limited here.

[0041] The third muffler 600 provided in this embodiment includes a base layer, a filling layer and a damping layer. The base layer guides sound waves into the filling layer to absorb high-frequency noise through viscous loss, which can significantly reduce high-frequency noise above 1000 Hz.

[0042] In one embodiment, it further comprises: a hood 700, which is mounted on the first end of the cylinder 100, and a ventilation gap is provided between the hood 700 and the wall of the cylinder 100, wherein the ventilation gap is annular. Figure 1 As shown, the hood 700 is fixed to the cylinder 100 by screw connection. The hood 700 is a brim structure protruding from the cylinder 100. The setting of the hood 700 can guide rainwater to flow down along the edge of the hood and avoid directly entering the interior of the ventilation tube. In this embodiment, by setting the hood 700, outdoor air can enter the ventilation tube through the ventilation gap (refer to Figure 1 As shown in the figure, outdoor air enters the cylinder 100 from the bottom to the top through the ventilation gap, which can optimize the direction of outdoor air flow, reduce the wind resistance in strong wind or headwind environment, and reduce the intrusion of foreign matter such as waves and droplets.

[0043] Optionally, sound-absorbing material may be provided on the hood 700 to reduce the intensity of external noise transmitted into the room through the ventilator.

[0044] In one embodiment, it further comprises: a net frame 800, which is covered at the ventilation gap and installed on the wind hood 700. In this embodiment, the net frame 800 can be provided to block marine floating objects.

[0045] It should be noted that the outer diameter of the screen frame 800 needs to be slightly smaller than the inner diameter of the hood 700, and the inner diameter of the screen frame 800 needs to be slightly larger than the outer diameter of the ventilation tube 100 to ensure that the area of the annular ventilation gap is not significantly affected.
