Abstract

This utility model discloses an amphibious vehicle power compartment air duct system, including a heat dissipation compartment (1), in which a power device (2) is installed. The power device (2) is usually an engine. The inner side of the heat dissipation compartment (1) is provided with a sliding structure for controlling the ventilation area inside the heat dissipation compartment (1). The sliding structure is a sliding plate (3) set on both sides of the heat dissipation compartment (1). The cross-sectional area of ​​the heat dissipation compartment (1) is controlled by the movement of the sliding plate (3). When the sliding plate (3) moves closer to each other, the cross-sectional area of ​​the heat dissipation compartment (1) decreases, the wind speed increases, and the heat dissipation capacity is improved. When the sliding plate (3) separates from each other, the cross-sectional area of ​​the heat dissipation compartment (1) increases, the wind speed slows down, and the wind howl is reduced. In this way, when the temperature inside the heat dissipation compartment (1) is high, the heat dissipation capacity can be improved by reducing the area and increasing the airflow speed. When the temperature inside the heat dissipation compartment (1) is low, the wind howl can be reduced by increasing the area and decreasing the airflow speed.

Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology. Specifically, this utility model relates to an amphibious vehicle power compartment air duct system. Background Technology

[0002] In the design of amphibious vehicles, ventilation and heat dissipation of the power compartment are one of the key aspects to ensure the normal operation of the vehicle.

[0003] A specification published on October 3, 2023, with application number 202320389502.2, discloses a heat dissipation structure for the power compartment of an amphibious vehicle. This structure includes a front air duct at the front of the power compartment, side air ducts on both sides of the power compartment, and a forced-exhaust heat dissipation chamber at the rear. The upper surface of the front air duct has a controllable air intake window, and the end of the front air duct has a radiator that draws in air into the power compartment. The two side air ducts are connected to the front air duct, and exchange windows are provided between them. The bottom of the side air ducts has a drainage channel connecting to the outside. The forced-exhaust heat dissipation chamber is used to extract hot air from the power compartment. This heat dissipation structure uses a three-section air intake duct system in conjunction with a radiator and a rear-mounted heat dissipation chamber to ventilate and cool the power compartment, avoiding the risk of malfunctions in wading situations, ensuring the normal output of the power components, and maintaining and improving the ventilation and heat dissipation effect inside and outside the power compartment in real time.

[0004] The existing amphibious vehicle power compartment ventilation system has air inlets and outlets that are too close together. Air is directly exhausted from the outlets without flowing sufficiently through the power compartment, which prevents the heat from being effectively dissipated. This reduces heat dissipation efficiency and affects the cooling of critical components such as the engine, leading to performance degradation and potentially overheating failures. This can affect the normal operation of the amphibious vehicle, reducing its safety and reliability. Traditional methods of increasing airflow to improve cooling increase wind noise and disrupt normal production activities. Utility Model Content

[0005] The present invention aims to provide an amphibious vehicle power compartment air duct system that can increase heat dissipation performance when necessary, and reduce wind noise when heat dissipation is not required.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an amphibious vehicle power compartment air duct system, including a heat dissipation compartment, a power device is provided inside the heat dissipation compartment, and a sliding structure for controlling the ventilation area inside the heat dissipation compartment is provided on the inner side of the heat dissipation compartment, wherein the sliding structure is a sliding plate provided on both sides of the heat dissipation compartment.

[0007] The slide plate is located on both sides of the power equipment. The two sides of the slide plate are provided with a central shaft that is hinged to the slide plate. The two ends of the central shaft are provided with ball bearings that contact the inner walls of the upper and lower sides of the heat dissipation chamber.

[0008] The two ends of the central shaft are hemispherical, and the ball bearings are embedded in the hemispherical structures at both ends of the central shaft.

[0009] A square sealing airbag is provided between the skateboard and the inner wall of the heat dissipation chamber, and the sealing airbag is in close contact with the inner wall surface of the skateboard.

[0010] The cross-section of the sealing airbag is corrugated.

[0011] A front baffle is hinged to one side of the skateboard via a central shaft, and the front baffle is hinged to the inner wall of the heat dissipation chamber.

[0012] A rear baffle is hinged to the other side of the slide plate via a central shaft. A sliding rod is provided on the side of the rear baffle away from the slide plate, and the sliding rod is slidably connected to the inner wall of the heat dissipation chamber.

[0013] The heat dissipation chamber is equipped with a slide rail, and the slide rod is installed inside the slide rail.

[0014] A retraction spring is provided between the end of the slide rod and the end of the slide rail.

[0015] The technical effect of this utility model is as follows: the cross-sectional area of ​​the heat dissipation chamber is controlled by the movement of the sliding plates. When the sliding plates move closer together, the cross-sectional area of ​​the heat dissipation chamber decreases, the wind speed increases, and the heat dissipation capacity is improved. When the sliding plates separate, the cross-sectional area of ​​the heat dissipation chamber increases, the wind speed decreases, and the wind howling is reduced. In this way, when the temperature inside the heat dissipation chamber is high, the heat dissipation capacity can be improved by reducing the area and increasing the airflow speed. When the temperature inside the heat dissipation chamber is low, the wind howling is reduced and the noise is reduced by increasing the area and decreasing the airflow speed.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0022] Please see Figure 1-3 An amphibious vehicle power compartment ventilation system includes a heat dissipation compartment 1, within which a power unit 2, typically an engine, is installed. The inner side of the heat dissipation compartment 1 is equipped with a sliding structure that controls the ventilation area within the compartment. This sliding structure consists of sliding plates 3 positioned on both sides of the heat dissipation compartment 1. The cross-sectional area of ​​the heat dissipation compartment 1 is controlled by the movement of the sliding plates 3. When the sliding plates 3 move closer together, the cross-sectional area of ​​the heat dissipation compartment 1 decreases, increasing the airflow speed and improving heat dissipation. When the sliding plates 3 separate, the cross-sectional area of ​​the heat dissipation compartment 1 increases, decreasing the airflow speed and reducing whistling. This allows for improved heat dissipation by reducing the surface area and increasing airflow velocity when the temperature inside the heat dissipation compartment 1 is high, and reduced whistling and noise by increasing the surface area and decreasing airflow velocity when the temperature inside the compartment 1 is low.

[0023] The slide plate 3 is located on both sides of the power device 2. The slide plate 3 has a central shaft 7 that is hinged to the slide plate 3 on both sides. The two ends of the central shaft 7 are provided with ball bearings 8 that contact the inner walls of the upper and lower sides of the heat dissipation chamber 1. The ball bearings 8 at both ends of the central shaft 7 abut against the inner wall surface of the heat dissipation chamber 1, so that there is a certain gap between the slide plate 3 and the inner wall of the heat dissipation chamber 1, preventing the slide plate 3 from rubbing against the inner wall of the heat dissipation chamber 1 during movement. At the same time, the presence of the ball bearings 8 also facilitates the movement of the slide plate 3, reduces the resistance to movement, and makes the movement of the slide plate 3 convenient.

[0024] The two ends of the central shaft 7 are hemispherical, and the ball bearings 8 are embedded in the hemispherical structures at both ends of the central shaft 7; this prevents the ball bearings 8 from falling off the two ends of the central shaft 7 during movement, and also does not affect the normal movement of the skateboard 3.

[0025] A square sealing airbag 6 is provided between the slide plate 3 and the inner wall of the heat dissipation chamber 1. The sealing airbag 6 is tightly attached to the inner wall surface of the slide plate 3. The slide plate 3 is made of thermally conductive metal. When the temperature inside the heat dissipation chamber is high, the sealing airbag 6 expands due to heat, pushing the slide plates 3 on both sides to move closer together. The cross-sectional area of ​​the heat dissipation chamber 1 decreases, the wind speed increases, and the heat dissipation capacity is improved, which can effectively reduce the temperature of the engine. In addition, the square sealing airbag 6 keeps the slide plate 3 horizontal at all times, preventing the slide plate 3 from rotating too much and the structure from jamming and being unable to reset.

[0026] The sealing airbag 6 has a corrugated cross-section, which allows it to expand faster and with a greater expansion amplitude when heated. This also allows the sliding plate 3 to move more freely and is more susceptible to temperature changes.

[0027] A front baffle 4 is hinged to one side of the slide plate 3 via the central shaft 7. The front baffle 4 is hinged to the inner wall of the heat dissipation chamber 1. As the two slide plates 3 move closer to each other, the distance between the slide plate 3 and the inner wall of the heat dissipation chamber 1 increases. The front baffle 4 blocks the gap between the slide plate 3 and the inner wall of the heat dissipation chamber 1 to prevent air leakage and ensure that the airflow speed is not increased.

[0028] On the other side of the slide plate 3, a rear baffle 5 is hinged to the central shaft 7. A slide rod 9 is provided on the side of the rear baffle 5 away from the slide plate 3. The slide rod 9 is slidably connected to the inner wall of the heat dissipation chamber 1: it blocks the gaps on the front and rear sides of the slide plate 3, preventing wind from passing through the space between the slide plate 3 and the inner wall of the heat dissipation chamber 1. At the same time, it can also fix the two ends of the slide plate 3, preventing the slide plate 3 from being blown away by the wind and failing to reduce the ventilation area inside the heat dissipation chamber 1.

[0029] The heat dissipation chamber 1 is equipped with a slide rail 10, and the slide rod 9 is installed in the slide rail 10; this allows the side of the rear baffle 5 to slide along the inner wall of the heat dissipation chamber 1, while also ensuring that the rear baffle 5 is always blocked between the slide plate 3 and the inner wall of the heat dissipation chamber 1, thus blocking the wind and preventing wind from entering between the slide plate 3 and the inner wall of the heat dissipation chamber 1.

[0030] A retraction spring 11 is provided between the end of the slide rod 9 and the slide rail 10. When the temperature inside the heat dissipation chamber 1 drops, the sealing airbag 6 contracts. Under the action of the retraction spring 11, the rear baffle 5 is pulled back to its original position, and the slide plate 3 is also pulled back to its original position under the action of the rear baffle 5. The ventilation area of ​​the heat dissipation chamber 1 is increased, which effectively reduces wind howling and noise.

[0031] Working principle: When the temperature inside the heat dissipation chamber is high, the sealing airbag 6 expands due to heat, pushing the sliding plates 3 on both sides to move closer together. The front baffle 4 and rear baffle 5 on both sides of the sliding plate 3 are pulled and rotated, blocking the gap between the sliding plate 3 and the inner wall of the heat dissipation chamber 1, thereby reducing the cross-sectional area of ​​the heat dissipation chamber 1, increasing the wind speed, improving the heat dissipation capacity, and effectively reducing the temperature of the engine.

[0032] When the temperature inside the heat dissipation chamber 1 drops, the sealing airbag 6 contracts. Under the action of the contraction spring 11, the rear baffle 5 is pulled back to its original position, and the sliding plate 3 is also pulled back to its original position under the action of the rear baffle 5. The ventilation area of ​​the heat dissipation chamber 1 increases, effectively reducing wind howling and noise.

[0033] The technical effect of this utility model is as follows: the cross-sectional area of ​​the heat dissipation chamber 1 is controlled by the movement of the sliding plate 3. When the sliding plates 3 move closer together, the cross-sectional area of ​​the heat dissipation chamber 1 decreases, the wind speed increases, and the heat dissipation capacity is improved. When the sliding plates 3 separate, the cross-sectional area of ​​the heat dissipation chamber 1 increases, the wind speed decreases, and the wind howling is reduced. In this way, when the temperature inside the heat dissipation chamber 1 is high, the heat dissipation capacity can be improved by reducing the area and increasing the airflow speed. When the temperature inside the heat dissipation chamber 1 is low, the wind howling can be reduced by increasing the area and decreasing the airflow speed, thus reducing noise.

[0034] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
