Technical Field

The invention relates to the technical field of engine tail gas treatment, in particular to a land tail gas cooling device and weapon equipment.

Background

In the military field, a more common technical means for detecting enemy weaponry is an infrared detection technology, and if the temperature difference between the exhaust gas discharged by an engine of the weaponry and the ambient environment is large, the enemy weaponry is easily detected by an infrared detection system and falls into danger, so that the attack capability and the security capability of the weaponry are greatly influenced.

So-called weaponry can be divided into at least water equipment and land equipment according to the region of operation, and the water equipment can be various warfare vessels, and the land equipment can be various combat vehicles. For the warship, in order to reduce the temperature of engine exhaust to avoid being detected by infrared detection system, often adopt the water intaking system to directly get water from the waters of naval vessel, then atomize water, later use water smoke to spray in the engine exhaust pipe in order to reach the purpose to the exhaust cooling. However, this kind of tail gas cooling technology is not suitable for land-used combat vehicles, and one can't continuously obtain stable water source, and the second water smoke in the exhaust pipe can be gasified rapidly after fully contacting with the high temperature tail gas and absorbing heat to produce a large amount of smog, and smog can cause the target to expose equally, and makes the combat vehicle be in danger.

The embodiment focuses on land weaponry as an example for explanation, and aims to solve the problem that the existing land weaponry is poor in infrared stealth capability due to overhigh temperature of exhaust gas, and is easy to cause target exposure and cause danger when military missions are executed.

For the convenience of understanding the technical solution, the following description will be made by taking a land weapon as a land chariot. As can be appreciated, a land craft includes a vehicle body, and a land based exhaust gas cooling device mounted on the vehicle body. The land tail gas cooling device is mainly used for reducing the temperature of exhaust tail gas generated by the work of the engine 11, so that the infrared detection difficulty of an enemy infrared detection system on the land combat vehicle of the owner is increased, and the survival capability of the land combat vehicle of the owner on the battlefield is improved.

As shown in fig. 1, a land tail gas cooling device according to an embodiment of the present application includes: the engine block 10, the heat exchanger 20, the coolant circulation assembly 30, and the heat sink assembly 40. The engine unit 10 is used for outputting high-temperature tail gas; generally speaking, the temperature of the exhaust gas discharged from the engine 11 can reach as high as 600 ℃ to 700 ℃, so that the exhaust gas is easily detected by an infrared detection system with advanced technology, and the shadow of the land battle vehicle is found and exposed to the attack target of the enemy. Therefore, the technical scheme of the embodiment is provided for reducing the temperature of the exhaust gas so as to improve the stealth capability of the land battle vehicle.

Wherein the heat exchanger 20 may be any type of heat exchange device known in the art; specifically, the heat exchanger 20 may be, but is not limited to, a pin tube heat exchanger 20, a shell-and-tube heat exchanger, or the like.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the land-used tail gas cooling device is applied to various weaponry, particularly to land-used weaponry, so that the temperature of tail gas emission is reduced, and the infrared stealth capability of equipment is improved. Specifically, when the engine unit 10 is operating normally, high-temperature exhaust gas can be continuously output; the high-temperature tail gas firstly flows into the heat exchanger 20, and at the same time, the cooling liquid in the cooling liquid circulation assembly 30 also flows into the heat exchanger 20, under the heat exchange action of the heat exchanger 20, the heat of the high-temperature tail gas is exchanged to the cooling liquid, so that the temperature of the cooling liquid is greatly increased, and the increased cooling liquid further flows into the heat dissipation assembly 40 to achieve the heat dissipation purpose, so that the heat absorption capacity is not affected by the overhigh temperature when the cooling liquid flows into the heat exchanger 20 again. So far, because the heat of high temperature tail gas has been given the coolant liquid by the exchange of overwhelming majority, therefore the tail gas temperature that finally discharges can descend by a wide margin, has weakened the infrared radiation characteristic of land weaponry, makes infrared detecting system be difficult to detect its shadow, has promoted the infrared stealthy ability of land weaponry to avoid the target to expose and fall into in danger. Simultaneously the land tail gas cooling device of this application has solved the water smoke among the prior art and has sprayed the defect that the cooling means is not applicable to land weapon equipment well.

The water tank 35 is connected to the second pipe line 33 via a fourth pipe line 36. Alternatively, the cooling liquid flowing through the cooling liquid circulation unit 30 is cooling water. The low-temperature cooling water flows into the heat exchanger 20 through the third pipeline 34 and can be heated by the high-temperature tail gas; the heated high-temperature cooling water flows back into the heat dissipation assembly 40 through the first pipeline 32, so that the heat of the heated cooling water can be discharged in time, the temperature of the cooling water is rapidly reduced, and the secondary heat absorption capacity is achieved. The cooled cooling water can flow into the heat exchanger 20 again through the water pump 31 to realize the circulating heat exchange with the high-temperature tail gas, so that the resource utilization rate is improved.

The temperature sensor 50 can detect the temperature of the cooling water flowing from the heat exchanger 20 into the heat dissipation assembly 40 in real time and transmit the temperature to the controller 60 in real time; when the controller 60 receives that the temperature of the cooling water at a certain moment continuously rises and reaches or even exceeds a preset threshold value, it represents that the temperature of the current cooling water is too high to have the heat exchange and heat absorption capacity with the high-temperature tail gas, and at the moment, the controller 60 controls the heat dissipation assembly 40 to be started to work, so that the cooling water flowing into the heat dissipation assembly 40 is subjected to heat dissipation and temperature reduction, and the heat exchange and heat absorption capacity of the cooling water is ensured.

Considering that particle impurities are generated in cooling water due to corrosion of the wall of the water tank 35, aging and falling of the wall of the heat exchanger 20 and the like in the year-round work, if the impurities flow into the water pump 31, the water pump 31 is easily blocked and damaged, and the device cannot work normally.
