Description

Thermal management system with infrared stealth and heat dissipation functions

Technical Field

The utility model belongs to the technical field of infrared stealth, more specifically the heat management system with infrared stealth compromise heat dissipation function that says so.

Background

Along with the rapid development of detection and reconnaissance technologies, in order to resist infrared detection, various detection technologies are applied to the existing battlefield in a competitive mode, the infrared stealth technology weakens infrared thermal characteristic signals of targets by a certain means, and enables the infrared thermal characteristic signals to be equivalent to the environmental background, so that the discovery probability of enemy detectors is reduced, further threats of weapons such as infrared guidance and the like to the targets are reduced, the survival probability of the targets is improved, and the technical approaches for realizing the infrared stealth of the targets are mainly two: reducing the target surface temperature and adjusting the surface emissivity.

The reduction of the surface temperature of the target and the adjustment of the surface emissivity are realized by changing the design of the structure and applying the infrared physical principle to attenuate and absorb the energy of infrared radiation of the target, thereby realizing the low detectability of a heat source target (heat source equipment). In operation, due to the thermal inertia of the device and the difference between the radiation properties of the surface material and the background, the thermal response of the device and the background to the external environment changes (such as solar radiation and air temperature changes) are different, so that the infrared radiation characteristics of the target and the background are remarkably different. And the target is in a heat source state for a long time after the maneuvering or movement stops, the temperature difference between the target temperature of the heat source and the background can reach 100 ℃, and the target temperature and the background are easy to become obvious exposure signs, so that the control of the surface temperature of the target of the heat source, the reduction of the temperature difference between the target and the background and the reduction of the infrared radiation of the target of the heat source are main infrared stealth measures.

For controlling the surface temperature of a heat source, a method is usually adopted in which a plurality of layers of heat insulating materials are added on the surface of a target to be concealed to form a thermal infrared concealed camouflage shield, so that a large amount of heat is blocked from being transferred to the surface of the target, and the infrared characteristic signal of the target is comprehensively reduced. This kind of mode occupation space is great, increases equipment external diameter size, and heat source equipment surface temperature can not change along with the change of environment moreover, and the thermal equipment surface does not have the environment followability, and heat source body surface temperature difference is big moreover, does not have the temperature uniformity. Meanwhile, for the places where heat source equipment needs to dissipate heat, the surface temperature control mode is difficult to dissipate heat, so that local heat generation is serious, and even devices are damaged easily.

In order to solve the above problems, the conventional method is to change the direction of heat conduction by an air duct to conduct the heat to the bottom of the heat source equipment, or to transfer the heat from the direction which is not easy to detect on the heat source equipment to the ambient air by changing the directions of a heat dissipation structure and a heat dissipation air duct and using an air convection mode, thereby reducing the surface temperature of the heat source equipment. However, these methods can be used only locally on the heat source target, and cannot completely cover the heat source surface. In addition, the heat dissipation modes have the defects that the heat dissipation inside the heat source equipment is insufficient, the internal temperature of the heat source equipment is still very high, the normal operation of a target is influenced, and particularly, under the condition of very high environmental temperature, parts inside the heat source equipment cannot normally operate. And the heat is conducted to the bottom of the target, so that the infrared characteristic of the bottom of the heat source equipment is obvious, and the integral temperature uniformity of the target is poor.

In order to facilitate the understanding of the technical solutions of the present invention by those skilled in the art, the technical solutions of the present invention will now be further described with reference to the specific embodiments and the drawings.

When the heat source equipment (needing stealth equipment) operates or operates for a long time, the interior of the heat source equipment is in a high temperature state, internal heat radiates outwards, and even if the heat source equipment is wrapped by a heat insulation material, a small amount of heat inside the heat source equipment radiates outwards through the heat insulation material, or the problem that the temperatures of all positions on the outer surface of the heat insulation material are inconsistent is caused. If a large temperature difference occurs between the outer surface temperature of the heat insulating material and the ambient temperature, the temperature is detected by infrared detection equipment, and becomes an obvious exposure sign. Or if the temperature of each position on the heat insulation material is not uniform, and a large temperature difference occurs locally, the heat source equipment can be detected by the infrared detection equipment, so that the heat source equipment can be exposed.

Meanwhile, the heat insulating material is wrapped outside the heat source equipment, so that the heat dissipation inside the heat source equipment is not facilitated, important devices or structural components with high heat generation inside the heat source equipment need to be dissipated in time, and otherwise, the problems of high-temperature damage or high-temperature burning-out can occur, such as an engine, a motor, a pump, a control mainboard, a control chip and the like. In order to solve the problem, a heat source device heat dissipation port is generally arranged on the heat source device to ensure normal heat dissipation of the heat source device, ensure normal operation of the heat source device, and prolong the service life of the heat source device.

Generally, the outer surface temperature of the heat source device 100 before starting is mainly determined by the ambient temperature, that is, the surface temperature of the heat source device 100 before starting is adapted to the ambient temperature, and the temperature of the stealth module covering the outside of the heat source device is also mainly determined and controlled by the ambient temperature and adapted to the ambient temperature. After the heat source equipment 100 is started, internal components thereof operate, a heat generation phenomenon occurs, and the internal temperature thereof is maintained at a certain high temperature state for a considerable period of time after the heat source equipment 100 stops operating.

According to the heat transfer principle, the heat inside the heat source device 100 tends to radiate outward through the surface of the heat source device 100, and tends to be convected outward from the heat source device heat-dissipating opening 103 on the heat source device 100. This may cause the temperature of the outer surface of the heat source device 100 to rise or a local high temperature to occur at the position of the heat sink of the heat source device, so that the heat source device 100 is easily detected by the infrared detection device. In order to solve the problem, the utility model discloses technical scheme one kind has infrared stealthy thermal management system who compromises heat dissipation function.

Therefore, the louver heat absorption module 1 is arranged, so that on one hand, the heat generated inside the heat source equipment 100 is absorbed in time, and the heat dissipation inside the heat source equipment is realized and ensured; on one hand, heat in convection air passing through the position of the louver heat absorption module 1 is absorbed, the original hot air convection position of the heat source equipment is moved to the position of the louver heat absorption module 1, air convection outside the heat source equipment is avoided, local high temperature around the heat source equipment is avoided being detected by an infrared detector, and indirect exposure of the heat source equipment is avoided; on the other hand, the internal temperature of the heat source equipment is controlled through timely internal heat dissipation and heat absorption in hot air, the internal temperature of the heat source equipment is prevented from being too high, excessive heat is prevented from being radiated outwards by the heat source equipment, the temperature rise of the outer surface of the stealth module covering the outside of the heat source equipment is avoided, the outer surface temperature of the stealth module 20 is controlled and ensured to be adaptive to the environment temperature, and the infrared stealth function of the heat source equipment is ensured.

Based on the above technical solution, the control and driving module 5 and the heat exchange module 2 are far away from the heat source device 100, that is, the control and driving module 5 and the heat exchange module 2 are arranged at a position far away from the louver heat absorption module 1, so as to avoid the influence on the stealth of the heat source device 100 and avoid the indirect exposure of the heat source device 100. The driving and control module 5 and the heat exchange module 2 are conventional equipment structures, and although heat is generated during operation, on one hand, the heat is low, the temperature difference with the environment is low, and on the other hand, the driving and control module and the heat exchange module exist on most conventional mechanical equipment and do not have target exposure.

Among this technical scheme, have infrared stealthy thermal management system independent control who compromises heat dissipation function, do not open with heat source equipment and stop simultaneously, tripe heat absorption module 1 can continuous work, can continue continuous work in heat source equipment 100 operation or the quite long period of time after shutting down, according to ambient temperature control circulation refrigerant temperature or circulation refrigerant delivery capacity, the realization is to carrying out accurate control of heat source equipment surface temperature, it changes along with ambient temperature change to realize heat source equipment external temperature, this thermal management system who has infrared stealthy compromise heat dissipation function promptly has the environment followability.

In the present embodiment, as shown in fig. 1, the stealth module 20 includes a housing 23 covering the heat source device 100, a heat insulation member 21 disposed on an inner surface of the housing 23, and a first heat exchange pipe 22 disposed between the heat insulation member 21 and the inner surface of the housing 23. The first heat exchange pipe 22 is communicated with the cold guide module 8, and the refrigerant circulating in the first heat exchange pipe 22 absorbs the heat radiated from the heat source equipment 100 to the shell 23.

Based on the technical scheme, the shell 23 is covered outside the heat source equipment 100, the first heat exchange tube 22 and the heat insulation assembly 21 can be conveniently installed on the reverse side, meanwhile, an interlayer can be formed between the heat insulation assembly 21 and the shell 23, heat passing through the heat insulation assembly 21 is prevented from being rapidly diffused into the air, the contact time of the hot air and the first heat exchange tube 22 is prolonged, the heat exchange effect and the heat exchange rate of the first heat exchange tube 22 and the shell 23 are improved, heat radiated onto the shell 23 by the heat source equipment 100 is absorbed by a circulating refrigerant in the first heat exchange tube 22, the outer surface temperature of the shell 23 is ensured to be adaptive to the ambient temperature, the low infrared detectability of the shell 23 is realized, and the stealth of a heat source positioned in the shell is realized. That is, the stealth module 20 in the technical solution is arranged, and the external full coverage of the heat source device 100 is realized through the stealth module 20, so as to realize the stealth of the heat source device. In the technical scheme, as shown in fig. 1, a housing heat dissipation port 102 communicated with a heat source equipment heat dissipation port 103 is arranged on a housing 23, the louver heat absorption module 1 comprises a louver component arranged at the position of the heat source equipment heat dissipation port 103 of the heat source equipment 100 and a second heat exchange tube 12 fixed on the louver component, and the second heat exchange tube 12 is communicated with the cold guide module 8. The heat transmitted from the louver assembly of the heat source equipment 100 to the outside is absorbed by the circulating refrigerant in the second heat exchange tube 12, and the heat emitted by the heat source equipment is prevented from directly entering the air by the heat source equipment radiating colleague, so that local high temperature is generated near the heat source equipment, and the stealth of the heat source equipment is influenced.

The louver assemblies are arranged, and by means of the shielding performance of the louver assemblies, internal devices of the heat source equipment are effectively shielded, so that only the louver plates of the louver assemblies can be observed when the heat source equipment is observed from the outside, and the hiding capacity of the heat source equipment is improved.

Based on the above technical scheme, by arranging the second heat exchange tube 12 on the louver assembly, when the hot air in the heat source equipment flows to the position of the heat dissipation port 102 of the shell, the heat in the hot air is immediately absorbed by the circulating refrigerant circulating in the second heat exchange tube 12, that is, in the process that the hot air flows outwards through the louver assembly, the heat in the hot air is gradually absorbed, the temperature of the hot air is gradually reduced, when the hot air flows out of the louver assembly, the temperature of the hot air is already reduced to a state suitable for the ambient temperature, and when the hot air is continuously discharged outwards, the problem that the heat source equipment is exposed due to the height of the local temperature cannot occur. Meanwhile, the second heat exchange tube 12 on the louver component absorbs heat in the heat source equipment, reduces the internal temperature of the heat source equipment, avoids damage to internal devices of the heat source equipment due to high temperature, avoids heat in the heat source equipment from radiating outwards through the outer surface of the heat source equipment, realizes control of the outer surface temperature of the heat source equipment to be adaptive to the ambient temperature, and avoids the problem that the heat source equipment is exposed due to the fact that the temperature difference between the outer surface temperature of the heat source equipment and the ambient temperature is too large.
