Description
Technical field:
the present utility model relates to a camouflage device, and more particularly, to a heat source camouflage device.
The background technology is as follows:
military targets such as diesel engines, gasoline engines, cooling towers arranged for engineering of underground command posts and the like have high surface temperature of heat sources, hot gas is discharged, and thermal infrared exposure symptoms are obvious, so that the safety of the military targets is seriously threatened, and the problem cannot be effectively solved.
The utility model comprises the following steps:
the utility model aims to provide a heat source camouflage device which can effectively solve the problem of heat infrared exposure of heat sources such as a diesel engine, a gasoline engine, a cooling tower and the like at present.
The technical scheme of the utility model is as follows: the utility model provides a heat source camouflage device, includes casing, fan M, heat source and shelter from thing A, and the casing has gas outlet, steam import, air conditioning import, fan M and the air conditioning import intercommunication of casing, the heat source has the steam export, and the steam export of heat source and the steam import intercommunication of casing, shelter from thing A is located the heat source top. When the thermal imaging system is used, the main reconnaissance direction is from the upper side, so that the shielding object A shields the heat source from the upper side, the thermal imaging system cannot observe the heat source from the upper side, and the thermal infrared exposure symptom of the surface of the heat source is weakened. The hot air outlet of the heat source discharges hot air, the hot air enters the hot air inlet of the shell, the fan M extracts ambient air and sends the ambient air into the cold air inlet of the shell, and two gases entering from the hot air inlet and the cold air inlet of the shell are mixed in the shell and then discharged from the air outlet of the shell. Because the ambient air temperature is lower, the temperature of the hot gas entering from the hot gas inlet of the housing will decrease within the housing. If the amount of ambient air drawn by the fan M is large, the temperature of the hot gas and the housing will be significantly reduced and the thermal infrared exposure symptoms will be significantly reduced. Thus, the thermal infrared exposure signs of both the surface of the heat source and the exiting hot gases are reduced.
As a preferred technical scheme, the heat source comprises one of a cooling tower, a diesel engine and a gasoline engine, the cooling tower comprises an air inlet, an air outlet and a fan N, when the heat source is the cooling tower, the hot air outlet of the heat source is the air outlet of the cooling tower, the diesel engine and the gasoline engine are respectively provided with a smoke outlet, when the heat source is the diesel engine, the hot air outlet of the heat source is the smoke outlet of the diesel engine, and when the heat source is the gasoline engine, the hot air outlet of the heat source is the smoke outlet of the gasoline engine. Cooling towers, diesel engines and gasoline engines are common military heat sources, and the surface temperatures of the cooling towers, the diesel engines and the gasoline engines are high and have thermal infrared exposure signs. For the cooling tower, the air outlet temperature is high, and the thermal infrared exposure symptoms are also present. For diesel engines and gasoline engines, the exhaust port has high exhaust temperature and also has thermal infrared exposure symptoms. The surface thermal infrared exposure problem of the three can be solved by using the shielding object A, and the high-temperature exhaust thermal infrared exposure symptoms of the high-temperature exhaust gas of the cooling tower, the diesel engine and the gasoline engine can be solved by using the mixed ambient air in the shell.
As a preferable technical scheme, the cooling tower is a closed cooling tower. When the external environment is contaminated or polluted, for example, the cooling tower is an open cooling tower, and the cooling water of the cooling tower is in direct contact with the external environment air, the cooling water is contaminated or the water quality is deteriorated, which may cause contamination or pipeline scaling in the engineering using the cooling tower; when the cooling tower is a closed cooling tower, the cooling water of the cooling tower is not contacted with the air of the external environment, so that the cooling water is not polluted or the water quality is not deteriorated, and the pollution or the pipeline scaling and the like in the engineering using the cooling tower are not caused, and therefore, the cooling tower related to military use is preferably a closed cooling tower.
As a preferable technical scheme, the device further comprises a shielding object B, wherein the shielding object B is positioned above the shell. While mixing ambient air reduces the temperature of the housing, thermal infrared exposure symptoms are reduced, which may still be higher than ambient temperature at lower ambient temperatures. Because enemy reconnaissance mainly comes from the upper air, the upper part is provided with the shielding object B to shield the shell, and the discovered possibility can be reduced.
As a preferred technical scheme, the solar heat collector further comprises a shielding object C, wherein the shielding object C is located on the side face of the shell and the side face of the heat source, the shielding object C is provided with an air inlet, when the air outlet of the shell is located on the side face of the shell, the shielding object C is provided with an opening at the air outlet of the shell, and when the air outlet of the shell is located on the upper face of the shell, the shielding object B is provided with an opening at the air outlet of the shell. When the air outlet of the shell is arranged on the side face of the shell, the direction of the air outlet of the shell is not vertical upwards, and the exposure sign of the air outlet of the shell in the main reconnaissance direction can be reduced. Taking ground reconnaissance along the plumb line as an example, the air outlet of the shell with the same area is vertical upwards, and the exposed area of the air outlet of the shell is the same as the area of the air outlet of the shell. Whereas if the air outlet of the housing is oriented horizontally, its exposed area in the plumb line is almost 0. That is, the air outlet is positioned on the side surface of the shell, so that the exposed area of the air outlet of the shell in the main reconnaissance direction is greatly reduced, and the exposure sign is also greatly reduced. The heat source and the shell are communicated and can be regarded as a whole, and the shielding object C is positioned on the side surfaces of the shell and the heat source, so that shielding can be formed on the side surfaces of the heat source and the shell, and the thermal infrared exposure symptoms of the side surfaces are reduced. When the fan M and the heat source in the shielding object C need to suck the gas, the gas can enter from the gas inlet of the shielding object C. When the air outlet of the shell is positioned on the side face of the shell, the opening is formed in the air outlet of the shell, and when the air outlet of the shell is positioned on the shell, the opening is formed in the air outlet of the shell, so that air discharged from the air outlet of the shell can be discharged to the outside of the shield C or the shield B and does not flow in the internal circulation of the shield C and the shield B, the air can be prevented from being inhaled by the fan M, the air inlet temperature of the fan M is increased, the air outlet temperature of the shell and the air outlet temperature of the shell are increased, and the thermal infrared exposure sign is enhanced.
As a preferable technical scheme, when the air outlet of the shell is positioned on the side face of the shell, the air outlet of the shell is positioned in the projection area of the shielding object B, the projection line of the projection area is a parallel projection line, the projection direction of the projection line of the projection area is directed to one side of the air outlet of the shell from the upper side of the shell, and the angle of the projection line of the projection area and the plumb line is an angle which is more than or equal to 0 degree and less than or equal to 80 degrees. The air outlet of the shell is a main thermal infrared exposure part, and the air outlet can be seen from one side of the air outlet of the shell when the shell is seen from the upper side of the shell during reconnaissance. Therefore, the projection direction of the projection line is set to be directed to the air outlet side of the shell from the upper side of the shell, and the included angle of the projection line and the plumb line is set to be an angle which is more than or equal to 0 degrees and less than or equal to 80 degrees. Shielding in this direction can significantly reduce the exposure signs of the air outlet of the housing. The air outlet of the shell is in the projection area of the shielding object B above, so that the air outlet of the shell can be shielded during reconnaissance along the parallel projection lines, and the exposure sign of the air outlet of the shell is reduced.
As a preferable technical scheme, when the heat source is a cooling tower, the fan N is communicated with an air inlet of the cooling tower. The fan N of the cooling tower is arranged outside the tower body of the cooling tower, so that the cooling tower and the shell can be conveniently designed in a matching way, and the selection range of the style and the processing capacity of the fan N is also large.
It should be noted that the materials and thicknesses of the shielding object a, the shielding object B and the shielding object C are not limited, and may be camouflage net, metal plates or shutters, reinforced concrete, vegetation, earth and stones, etc., one material, or a combination of several materials, such as a camouflage net erected outside a metal plate or a shutter, and all objects capable of playing a role of shielding are included in the shielding object of the present utility model. The openings of the shielding object B and the shielding object C can be large openings, and the air outlet of the shell can be arranged in the opening or extend out of the opening; when the air outlet of the shell is arranged in the opening, the opening can also be a plurality of small openings, and the air can pass through the opening. Sometimes, for ease of placement or material saving, the shade a and the shade B may be joined together. Because the local exposure of the target is not necessarily found, the obstruction need not be a complete obstruction to the heat source or housing, but may be a partial obstruction. The hot gas inlet and the cold gas inlet of the shell are opposite, and only the fact that the gas temperature of the hot gas inlet is higher than that of the cold gas inlet is shown, so that the hot gas is not necessarily hot, and the cold gas is necessarily cold.
The utility model has the advantages of mainly solving the problem of thermal infrared exposure of heat sources such as diesel engines, gasoline engines, cooling towers and the like, along with simple structure and convenient implementation. The heat source cooling tower is optimized in combination with military use, such as a selective closed cooling tower, so that the heat source cooling tower can be better used for military use.
