Description

Technical fields:

[0001] This invention relates to the field of thermal infrared camouflage technology, and in particular to an exhaust device and a thermal infrared camouflage smoke elimination device and a cooling device having the same. Background technology:

[0002] Diesel engines, gasoline engines, cooling towers, and other heat sources are widely used on battlefields or in military engineering. These devices emit hot gases during operation, or can be ventilated by fans or other ventilation equipment to dissipate heat through these hot gases. The openings of these hot gas exhaust channels exhibit obvious thermal infrared exposure, making them thermal infrared targets on the battlefield and vulnerable to attack. Patent applications with application numbers 202322887702.3 and 202220462339.3 relate to exhaust devices that provide thermal infrared camouflage for the openings of these hot gas exhaust channels. In these patent applications, the opening of the hot gas exhaust channel is generally referred to as an exhaust nozzle; in addition to the exhaust nozzle, it also includes a shielding cover or sleeve, collectively referred to as a shielding object, which is located above or around the exhaust nozzle. In these patent applications, to prevent the hot gases emitted from the exhaust nozzle from heating the shielding object, the direction of the exhaust nozzle outlet is designed to avoid the shielding object as much as possible. This causes the following problem: when a thermal imager is used to take a picture from the air at a certain angle or towards the exhaust nozzle, the exhaust outlet can be captured. Since the exhaust outlet emits hot gas, its temperature is much higher than the ambient temperature, resulting in obvious thermal infrared exposure and making it detectable, thus failing to meet the requirements for thermal infrared camouflage. When applied to heat sources with large hot gas flow rates, such as cooling towers, and when the exhaust nozzle is large, such as with a diameter of 1 meter or more, the exposure is even more obvious. Summary of the Invention:

[0003] The purpose of this invention is to overcome the problems existing in the prior art and provide an exhaust device with a simple structure that can reduce the thermal infrared exposure of the exhaust nozzle outlet.

[0004] The present invention also provides a thermal infrared camouflage smoke elimination device, which has the above-mentioned exhaust device and can reduce the optical and thermal infrared exposure characteristics of exhaust heat sources such as diesel generators.

[0005] The present invention also provides a thermal infrared camouflage cooling device having the above-mentioned exhaust device, which can reduce the optical and thermal infrared exposure characteristics of the cooling tower.

[0006] The technical solution of this invention is:

[0007] An exhaust device includes an exhaust nozzle and a shield. The exhaust nozzle has an inlet and an outlet. The inlet of the exhaust nozzle is a hot air inlet. The device also includes a ventilation device. The shield is located above, to the side, or below the exhaust nozzle. The outlet of the exhaust nozzle faces the shield. There is a gas passage between the shield and the outlet of the exhaust nozzle. The outlet of the ventilation device is connected to the gas passage. The inlet of the ventilation device is connected to the ambient air.

[0008] As a preferred technical solution, it also includes thermal insulation material, and the wall surface of the exhaust nozzle is provided with thermal insulation material.

[0009] As a preferred technical solution, it also includes a flow guiding device, which is located at the inlet of the gas channel.

[0010] As a preferred technical solution, the angle α between the outlet direction of the exhaust nozzle and the surface of the shield to which the exhaust nozzle outlet faces is greater than 5 degrees and less than 180 degrees.

[0011] A thermal infrared camouflage smoke elimination device includes a smoke elimination device and the aforementioned exhaust device. The outlet of the smoke elimination device is connected to the inlet of the exhaust nozzle of the exhaust device. The inlet of the smoke elimination device is a hot flue gas inlet. The smoke elimination device is an electrostatic precipitator or a filter dust collector.

[0012] As a preferred technical solution, it also includes a shield B, which is disposed above the thermal infrared camouflage and smoke elimination device.

[0013] A thermal infrared camouflage cooling device includes a cooling tower and the aforementioned exhaust device, wherein the outlet of the cooling tower and the inlet of the exhaust nozzle of the exhaust device are connected.

[0014] As a preferred technical solution, it also includes a shielding object C, which is disposed above the thermal infrared camouflage cooling device.

[0015] The principle of this invention is as follows:

[0016] The principle of the exhaust system is as follows: hot gas enters through the inlet of the exhaust nozzle, passes through the nozzle, and exits through the outlet. A shield is located above, to the side, or below the exhaust nozzle, with the outlet facing the shield. A gas channel exists between the shield and the exhaust nozzle outlet; the outlet of the ventilation equipment is connected to this gas channel, and the inlet of the ventilation equipment is connected to ambient air. When the ventilation equipment is activated, the inlet draws in ambient air and delivers it to the gas channel through the outlet. Because the exhaust nozzle outlet faces the shield, the hot gas from the outlet flows towards the shield. Since the ventilation equipment introduces ambient air into the gas channel between the shield and the exhaust nozzle outlet, a layer of ambient air is formed between the shield and the hot gas exiting the exhaust nozzle outlet. This layer of ambient air isolates the hot gas from the shield, preventing the shield from being heated and eliminating thermal infrared exposure. This insulating layer of ambient air is called the ambient air isolation layer, and this technique of using ambient air to isolate hot gas is called air layer isolation technology. The airflow guiding device is located at the inlet of the gas passage between the shield and the exhaust outlet. Its function is to guide the airflow entering the gas passage, allowing ambient air to better isolate the hot air discharged from the exhaust outlet from the shield. For example, it can guide more ambient air towards the surface of the shield directly in front of the exhaust outlet, ensuring the formation of an ambient air isolation layer and preventing the shield from being heated. It can also guide ambient air towards other easily heated areas. Furthermore, the airflow guiding device can also shield the ventilation equipment behind it, reducing the exposure symptoms of the ventilation equipment. Since the exhaust outlet of this invention faces the shield, when a thermal infrared imager detects and photographs the exhaust outlet from the outside, the exposed area of ​​the exhaust outlet in the detection direction is reduced, thereby reducing its exposure symptoms. If the obstruction is above the exhaust nozzle, and the angle α between the exhaust nozzle's outlet direction and the surface of the obstruction towards which the exhaust nozzle's outlet faces is close to 90 degrees (meaning the exhaust nozzle's outlet is nearly perpendicular to the obstruction), then when viewed from the outside at eye level, the exhaust nozzle's outlet will appear almost as a line in the reconnaissance direction, significantly reducing its exposed area and consequently its exposure characteristics. If the angle is greater than 90 degrees, the exhaust nozzle's outlet will be completely invisible from the outside. Adjusting the length and angle α of the obstruction extending beyond the exhaust nozzle can achieve a situation where the exhaust nozzle's outlet is invisible even during oblique aerial reconnaissance. Because hot gas flows inside the exhaust nozzle, the nozzle's wall temperature is high. Insulating materials on the exhaust nozzle reduce its thermal infrared exposure characteristics. Thus, by having the exhaust nozzle's outlet facing the obstruction, its exposed area in the reconnaissance direction is reduced, but the obstruction itself is not heated due to the air layer's insulating effect, achieving the goal of reducing the exhaust nozzle's thermal infrared exposure characteristics.

[0017] The principle of thermal infrared camouflage smoke suppression devices is as follows: Heat sources such as diesel engines, which produce exhaust smoke, are major heat sources on the battlefield. This smoke is colored, resulting in significant optical exposure. Smoke suppression devices can eliminate this smoke, reducing its optical exposure. Electrostatic precipitators can eliminate black smoke and white or blue mist in the exhaust, completely eliminating optical exposure. Filter-type dust collectors use ceramic or metal filters to remove solid particles from the exhaust, eliminating only black smoke and reducing its optical exposure. When the exhaust pipes of these heat sources are connected to the inlet of the smoke suppression device, the smoke passes through the device, reducing its optical exposure. The outlet of the smoke suppression device is connected to the inlet of the exhaust nozzle of the exhaust system, further reducing the thermal infrared exposure of the exhaust. Since reconnaissance of ground targets generally comes from above, placing a shield (B) above the thermal infrared camouflage smoke suppression device is the most effective way to reduce exposure. Shield B can be camouflage netting, sheet metal, or concrete slabs, etc. If necessary, other obstructions can be installed on the sides of the thermal infrared camouflage smoke elimination device, or the obstructions can be connected to form an equipment room, with openings in the equipment room for the thermal infrared camouflage smoke elimination device to exhaust smoke, allow smoke in, or allow air in. Obstruction B can reduce the optical and thermal infrared exposure characteristics of the thermal infrared camouflage smoke elimination device.

[0018] The principle of the thermal infrared camouflage cooling device is as follows: Cooling towers are heat dissipation devices in underground military engineering projects such as command posts and communication systems. Their exhaust temperatures are high, and their outlets exhibit significant thermal infrared exposure characteristics. The outlet of the cooling tower is connected to the inlet of the exhaust nozzle of the exhaust device, which reduces the thermal infrared exposure characteristics at the cooling tower outlet. Reconnaissance of ground targets generally originates from above; placing a shield C above the thermal infrared camouflage cooling device is the most effective way to reduce exposure. The shield C can be camouflage netting, sheet metal, or concrete slabs, etc. If necessary, other shields can also be placed on the sides of the thermal infrared camouflage cooling device, or the shields can be connected to form an equipment room with openings for exhaust or intake air. The shield C reduces the optical and thermal infrared exposure characteristics of the thermal infrared camouflage cooling device's exterior.

[0019] Here are a few points to note:

[0020] 1. In this invention, the shielding object can be a flat plate or an arc-shaped plate, or it can be the enclosure structure of the equipment room, such as a ceiling or wall, or sometimes the ground. The shielding object can be installed at one location of the exhaust nozzle; alternatively, shielding objects can be installed at multiple locations simultaneously, with the exhaust nozzle outlet facing only one of the shielding objects. Besides the shielding object facing the exhaust nozzle outlet, connecting objects such as plates or brackets can be installed at other locations around the exhaust nozzle to facilitate fixing the exhaust nozzle and shielding object, connecting ventilation equipment, etc.

[0021] 2. In this invention, there is a gas passage between the shield and the outlet of the exhaust nozzle, and the outlet of the ventilation equipment is connected to the gas passage. As long as the outlet of the ventilation equipment and the gas passage are connected, the airflow from the ventilation equipment can enter the gas passage, regardless of the manner or location by which the airflow enters the passage, it is included within the scope of protection of this invention.

[0022] 3. The flow guiding device described in this invention is located at the inlet of the gas passage between the shield and the outlet of the exhaust nozzle. This means it can be located at the inlet or adjacent to it. Located here, it guides the ambient air entering the gas passage, primarily directing it towards the shield, thus facilitating the formation of an ambient air isolation layer between the shield and the hot air exiting the exhaust nozzle. A portion of the flow guiding device can also be used to direct some of the ambient air to other areas that may be heated by the hot air. The flow guiding device can be plate-shaped or of other forms; anything that can guide airflow is included within the scope of this invention.

[0023] The present invention has the following advantages over the prior art:

[0024] 1. Existing technologies, in order to prevent the hot air from the exhaust nozzle from heating the shield, avoid directing the exhaust nozzle outlet towards the shield. This results in a large exposed area of ​​the exhaust nozzle outlet in the detection direction, leading to obvious thermal infrared exposure. The technical approach of this invention is to direct the exhaust nozzle outlet towards the shield, reducing the exposed area of ​​the exhaust nozzle outlet in the detection direction. Then, ambient air is introduced using ventilation equipment, forming an ambient air isolation layer between the exhaust nozzle outlet and the shield, preventing the shield from being heated and eliminating thermal infrared exposure. This achieves the goal of reducing the thermal infrared exposure of the exhaust nozzle outlet. The technical approach of this invention differs significantly from existing technologies and offers obvious advantages.

[0025] 2. The airflow guiding device of the present invention can shield the ventilation equipment behind it, reducing the exposure symptoms of the ventilation equipment.

[0026] 3. The thermal infrared camouflage smoke elimination device of the present invention combines the smoke elimination device with the above-mentioned exhaust device, and provides a shield B on the upper part, which can reduce the optical and thermal infrared exposure characteristics of exhaust heat sources such as diesel generators.

[0027] 4. The invention provides a thermal infrared camouflage cooling device, which combines a cooling tower with the aforementioned exhaust device and has a shielding object C on the top, which can reduce the optical and thermal infrared exposure of the cooling tower. Attached image description:

Detailed implementation method:

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] like Figure 1 and Figure 2 An exhaust device is shown, including an exhaust nozzle 1 and a shield 2. The exhaust nozzle 1 has an inlet 3 and an outlet 4. The inlet 3 of the exhaust nozzle 1 is a hot air inlet. It also includes a ventilation device 5. The shield 2 is located above the exhaust nozzle 1. The outlet 4 of the exhaust nozzle 1 faces the shield 2. There is a gas passage 6 between the shield 2 and the outlet 4 of the exhaust nozzle 1. The outlet 7 of the ventilation device 5 and the gas passage 6 are connected through a first connecting pipe 12. The inlet 8 of the ventilation device 5 is connected to the ambient air.

[0035] It also includes thermal insulation material, and the wall of the exhaust nozzle 1 is provided with thermal insulation material 9.

[0036] It also includes a flow guiding device 10, which is located at the inlet 11 of the gas channel 6. The flow guiding device 10 is an adjustable-angle flat plate.

[0037] The angle α between the outlet 4 of the exhaust nozzle 1 facing direction 25 and the surface 26 of the shield 2 facing the outlet 4 of the exhaust nozzle 1 is 100 degrees, which can make the shield 2 better shield the outlet 4 of the exhaust nozzle 1.

[0038] The shield 2 is an arc-shaped plate. To facilitate fixing the exhaust nozzle 1 and connecting the ventilation equipment 5, a connector 24 is provided at the lower part of the exhaust nozzle 1. The connector 24 is also an arc-shaped plate. The connector 24 is connected to the shield 2, which can fix the exhaust nozzle 1 and can also be conveniently connected to the ventilation equipment 5 or the first connecting pipe 12 together with the shield 2.

[0039] The thick dashed arrows in the diagram indicate the direction of hot gas flow, while the thick solid arrows indicate the direction of ambient air flow.

[0040] The principle of the exhaust device in this embodiment is as follows: hot gas enters from the inlet 3 of the exhaust nozzle 1, passes through the exhaust nozzle 1, and is discharged from the outlet 4 of the exhaust nozzle 1. The shield 2 is located above the exhaust nozzle 1, and the outlet 4 of the exhaust nozzle 1 faces the shield 2. A gas passage 6 exists between the shield 2 and the outlet 4 of the exhaust nozzle 1. The outlet 7 of the ventilation device 5 and the gas passage 6 are connected through a first connecting pipe 12, and the inlet 8 of the ventilation device 5 is connected to the ambient air. When the ventilation device 5 is activated, the inlet 8 of the ventilation device 5 draws in ambient air and sends it from the outlet 7 through the first connecting pipe 12 into the airflow passage 6. Because the outlet 4 of the exhaust nozzle 1 faces the shield 2, the hot gas from the outlet 4 of the exhaust nozzle 1 flows towards the shield 2. Because the ventilation equipment 5 introduces ambient air into the gas channel 6 between the shield 2 and the outlet 4 of the exhaust nozzle 1, a layer of ambient air will be formed between the shield 2 and the hot air discharged from the outlet 4 of the exhaust nozzle 1. This layer of ambient air will isolate the hot air discharged from the outlet 4 of the exhaust nozzle 1 from the shield 2, so that the shield 2 is not heated and there are no signs of thermal infrared exposure.

[0041] The airflow guiding device 10 is located at the inlet 11 of the gas passage 6 between the shield 2 and the outlet 4 of the exhaust nozzle 1. Its function is to guide the airflow entering the gas passage, allowing ambient air to better separate the hot air discharged from the outlet 4 of the exhaust nozzle 1 from the shield 2. For example, it can guide more ambient air towards the surface of the shield 2 directly in front of the outlet 4 of the exhaust nozzle 1, ensuring the formation of an ambient air isolation layer and preventing the shield from being heated. The airflow guiding device 10 can guide the airflow through the air passage 6 as shown in the figure, or it can adjust the angle of some of the plate-shaped airflow guiding device to direct some of the airflow to other parts that may be heated by the hot air. Furthermore, the airflow guiding device 10 can also shield the ventilation equipment 5 behind it, reducing the exposure of the ventilation equipment 5. Since the outlet 4 of the exhaust nozzle 1 faces the shield 2, when the thermal infrared imager detects and photographs the exhaust nozzle 1 from the outside, the exposed area of ​​the outlet 4 of the exhaust nozzle 1 in the detection direction is reduced, thereby reducing its exposure. In this embodiment, the angle α between the outlet 4 of the exhaust nozzle 1 facing direction 25 and the surface 26 of the shielding object 2 facing the outlet 4 of the exhaust nozzle 1 is 100 degrees. When viewed from the outside, the outlet 4 of the exhaust nozzle 1 is completely invisible from the outside, greatly reducing its thermal infrared exposure. Because hot gas flows inside the exhaust nozzle 1, the wall temperature of the exhaust nozzle 1 is relatively high. The wall of the exhaust nozzle 1 is provided with heat-insulating material, which can reduce the thermal infrared exposure of the exhaust nozzle 1. In this way, the purpose of reducing the thermal infrared exposure of the outlet 4 of the exhaust nozzle 1 is achieved.

[0042] like Figure 3 The illustrated thermal infrared camouflage smoke suppression device includes a smoke suppression device 13 and the aforementioned exhaust device. The outlet 14 of the smoke suppression device 13 and the inlet 3 of the exhaust nozzle 1 of the exhaust device are connected by a second connecting pipe 17. The inlet 15 of the smoke suppression device 13 is a hot flue gas inlet. The smoke suppression device 13 is an electrostatic precipitator. It also includes a shield B16, which is disposed above the thermal infrared camouflage smoke suppression device. The shield B16 is a concrete slab.

[0043] The principle of the thermal infrared camouflage smoke suppression device is as follows: Heat sources such as diesel engines that emit smoke are major heat sources on the battlefield. Their smoke is colored, and its optical exposure is obvious. The smoke suppression device 13 is an electrostatic precipitator that can eliminate the optical exposure of the smoke. After the exhaust pipes of these heat sources are connected to the inlet 15 of the smoke suppression device 13, the optical exposure of the smoke is reduced as it passes through the device. The outlet 14 of the smoke suppression device 13 and the inlet 3 of the exhaust nozzle 1 of the exhaust device are connected by a connecting pipe 17, which reduces the thermal infrared exposure of the exhaust outlet. Since reconnaissance of ground targets generally comes from above, placing the obstruction B16 above the thermal infrared camouflage smoke suppression device is the most effective way to reduce exposure.

[0044] like Figure 4The thermal infrared camouflage cooling device shown includes a cooling tower 19 and the aforementioned exhaust device. The outlet 20 of the cooling tower 19 and the inlet 3 of the exhaust nozzle 1 of the exhaust device are connected by a third connecting pipe 21.

[0045] It also includes a shielding object C22, which is positioned above the thermal infrared camouflage cooling device. The shielding object C22 is an iron plate.

[0046] The principle of the thermal infrared camouflage cooling device is as follows: Cooling tower 19 is a heat dissipation device for underground military engineering projects such as command posts and communication systems. Its exhaust temperature is high, and the outlet exhibits obvious thermal infrared exposure characteristics. The outlet 20 of cooling tower 19 and the inlet 3 of exhaust nozzle 1 of the exhaust device are connected by a third connecting pipe 21. The exhaust from cooling tower 19 is discharged to the outside through the exhaust device. Because the exhaust device can reduce the thermal infrared exposure characteristics of the outlet 4 of exhaust nozzle 1, the thermal infrared exposure characteristics of the cooling tower exhaust outlet can be reduced by using the exhaust device. Generally, reconnaissance of ground targets mainly comes from above the target. Placing the obstruction C22 above the thermal infrared camouflage cooling device can most effectively reduce exposure.

[0047] If there is no enclosure structure or other shielding in the equipment room, the walls of the second connecting pipe 17 and the third connecting pipe 21 are insulated with thermal insulation material, such as thermal insulation material 18 for the second connecting pipe and thermal insulation material 23 for the third connecting pipe, to prevent these connecting pipes from being exposed to thermal infrared radiation.

[0048] In this embodiment, the flow guiding device 10 is located in the inlet 11 of the gas passage 6 between the shield 2 and the outlet 4 of the exhaust nozzle 1, or it can be located in the first connecting pipe 12 adjacent to the inlet. These locations at the inlet 11 can guide the ambient air entering the gas passage 6.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
