Description

Technical Field

[0001] This invention relates to the field of heat dissipation technology for cargo barges, and in particular to a high-efficiency heat dissipation system and method for heavy-tonnage open-hull barges. Background Technology

[0002] Heavy-tonnage open-hull barges are widely used in port construction, marine material transport, and land reclamation operations. Their hulls typically house high-powered diesel engines and auxiliary equipment, which release significant heat and generate exhaust pollutants during continuous operation. However, most existing open-hull barges lack dedicated ventilation and cooling systems during the design and construction phases, relying primarily on natural ventilation based on thermal and wind pressure through open hatches. This results in low overall ventilation efficiency, turbulent airflow, and difficulty in establishing stable and effective air convection channels. During hot seasons or prolonged continuous operation, the temperature inside the hull can rapidly rise to over 60°C, and even higher in some areas, leading to a significant deterioration of the internal thermal environment.

[0003] Meanwhile, toxic and harmful gases such as carbon monoxide, hydrogen sulfide, nitrogen oxides, and sulfur dioxide produced during diesel engine combustion accumulate continuously in enclosed or semi-enclosed spaces, making them difficult to expel in a timely manner. This not only seriously affects air quality but also greatly increases the risk of poisoning, suffocation, and other safety accidents. High-temperature environments also adversely affect the operation of ship equipment, such as reducing engine intake air density and combustion efficiency, causing performance degradation in the cooling and lubrication systems, further increasing engine coolant and oil temperatures, accelerating wear on mechanical components, and increasing the probability of malfunctions and maintenance costs.

[0004] Furthermore, the combination of high temperatures and flammable gases inside the hull can trigger extreme safety risks such as explosions, posing a serious threat to the overall operation of the vessel. In some overseas projects or regions with scarce resources, traditional complex cooling systems are difficult to implement due to limitations in material supply, construction conditions, and cost control. Therefore, how to effectively improve the ventilation and heat dissipation efficiency of open-hull barge hulls, reduce internal temperatures, and promptly expel harmful gases while ensuring structural simplicity, convenient construction, and controllable costs has become a critical technical problem that urgently needs to be solved. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a high-efficiency heat dissipation system and method for heavy-tonnage open-hull barges.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention provides a high-efficiency heat dissipation system for heavy-tonnage open-hull barges, the device including heat dissipation openings: Two heat dissipation openings are provided. One of the heat dissipation openings is an air intake opening, which can be opened at any position according to the deck layout requirements of the open-body barge. The other heat dissipation opening is an exhaust opening, which is set on the deck of the open-body barge near the cabin, and the distance between the exhaust opening and the cabin is 20cm. The diameter of the air intake opening and the exhaust opening is the same, and the diameter is set to 35cm. An intake pipe column is installed directly above the intake opening, and an exhaust pipe column is installed at the top of the exhaust opening. Both the intake pipe column and the exhaust pipe column are made of steel pipe, and the inner diameter of the pipe column is uniformly set to 36cm. The top of the intake and exhaust pipes is equipped with a waterproof cover, which is also made of steel pipe with a thickness of 5mm. Multiple auxiliary steel bars arranged in a ring are welded to one end of the inner wall of the waterproof cover, and the other end of the auxiliary steel bars is welded to the side wall of the intake and exhaust pipes. Cooling fans are installed at the bottom of both the air intake and exhaust vents. The cooling fans are square-structured open-body barge power supply matching models, and the length and width of the cooling fans are both 40cm.

[0007] Furthermore, in a preferred embodiment of the present invention, bolt anchoring holes are provided around the location of the air intake opening on the open barge deck for fixing the cooling fan.

[0008] Furthermore, in a preferred embodiment of the present invention, the diameter of the bolt anchoring hole is 5mm, and four bolt anchoring holes are reserved at each heat dissipation opening.

[0009] Furthermore, in a preferred embodiment of the present invention, both the intake manifold and the exhaust manifold are connected to the deck of the open-hull barge by full welding.

[0010] Furthermore, in a preferred embodiment of the present invention, an exhaust hole is provided at the top of the intake pipe and the exhaust pipe, which is toothed, and the depth of the exhaust hole is 20cm.

[0011] Furthermore, in a preferred embodiment of the present invention, the cooling fan is connected and fixed by four 5mm bolts and bolt anchor holes.

[0012] The second aspect of this invention provides a heat dissipation method for a high-efficiency heat dissipation system for a heavy-tonnage open-hull barge, applicable to any of the high-efficiency heat dissipation systems for heavy-tonnage open-hull barges described in any one of the claims, specifically including the following steps: S01: Obtain the thermal energy point sources of the open-hull barge cabin, construct the distributed thermal coupling nodes of the thermal energy point sources and the space cabin heat exchange model, analyze the spatial thermal coupling effect of the thermal energy point sources on the cabin using multi-source thermal correlation data, and couple the dynamic thermal energy conditions of each distributed thermal coupling node in the space cabin heat exchange model based on the spatial thermal resistance topology of the spatial thermal coupling effect to generate a global thermal dynamic model of the open-hull barge cabin. S02: The cabin sub-domains of the open-hull barge are divided by the layout of the power facility units of the open-hull barge. Based on the predetermined tolerance parameters of the power facility units to high temperature thermal energy, the observation perspective factor of the critical response thermal radiation of each cabin sub-domain is calculated. The observation perspective factor is substituted into the global energy dynamic model for coupled solution to obtain the real-time temperature energy distribution field of the open-hull barge cabin. S03: Extract temperature dynamic vector data of the open barge cabin based on the real-time temperature energy distribution field, analyze the thermal temperature trend stability of the open barge cabin through continuous vector similarity analysis of the temperature dynamic vector data, obtain real-time steady-state approximate entropy information, and perform peak analysis on the real-time steady-state approximate entropy information based on the approximate entropy information of thermal runaway to determine the high temperature runaway anomaly of the open barge cabin. S04: When the open-hull barge cabin experiences an abnormal high temperature runaway, the cooling fan will be activated to quickly expel the high-temperature air from the open-hull barge cabin through the exhaust vents and exhaust pipe, thereby rapidly cooling the interior of the open-hull barge cabin.

[0013] Furthermore, in a preferred embodiment of the present invention, step S01 specifically includes the following steps: The heat energy point sources of the open-hull barge are obtained, and the dynamic heat energy conditions of each heat energy point source during the predetermined time period are collected through the shipborne Internet of Things. Obtain a schematic diagram of the heat dissipation channels for each heat source located in the open-hull barge cabin through the heat dissipation management log, and establish distributed thermal coupling nodes for the heat sources based on the heat dissipation channel schematic diagram. Analyze the potential thermal state changes under dynamic thermal energy conditions, define the thermal energy emission amplitude of different distributed thermal coupling nodes, and simultaneously acquire the structural design drawings of the open barge cabin and multi-source thermal correlation data of the heat released towards the open barge cabin under the premise of dynamic thermal energy conditions of each thermal energy point source. The multi-source thermal correlation data includes cabin air temperature, cabin temperature-pressure difference, indoor temperature rise amplitude, temperature rise gradient, indoor temperature rise rate, heat flow direction, and convective wind speed. Introducing the theory of heat energy transfer, a space heat exchange model of the open barge cabin is constructed based on the structural design drawings. Based on the theory of heat energy transfer as the distribution criterion, the spatial thermal coupling effect of each heat energy point source on the open barge cabin is calculated using multi-source heat correlation data, and the spatial thermal coupling effect coefficient of each heat energy point source is obtained. Based on the space thermal coupling effect coefficient, a topology calculation is performed on the space cabin heat exchange model and the distributed thermal coupling nodes to generate a space thermal resistance network of open barge cabin-heat energy point source. Based on the thermal energy emission amplitude, a spatial thermal resistance network is used to establish and solve the thermal energy balance equation for each distributed thermal coupling node, thereby obtaining the dynamic heat exchange degree of the thermal energy point source. All the dynamic heat exchange degrees are spatiotemporally coupled to generate a global thermodynamic model of the open-body barge cabin.

[0014] Furthermore, in a preferred embodiment of the present invention, step S02 specifically includes the following steps: Obtain the hull dynamic layout diagram of the open-hull barge, obtain the power facility units of the open-hull barge hull through the hull dynamic layout diagram, and divide the open-hull barge hull into N hull subdomains according to the topological deployment of the power facility units. Obtain the model and specification information of the power facility unit, and retrieve the subcritical tolerance range of thermal energy for each power facility unit under different high temperature environmental conditions based on big data retrieval of the model and specification information; The limiting radiation boundary of each cabin subdomain is discretized into several thermal response infinitesimal integrals. The thermal response infinitesimal integrals are observed and weighted based on the radiation sensing of the subcritical tolerance range to generate the thermal radiation observation weight of each thermal response infinitesimal integral. The thermodynamic finite element algorithm is introduced to calculate the perspective scale of the thermal radiation observation weight, and the observation perspective factor value of each thermal response infinitesimal integral is obtained. According to the thermal radiation law, all observation perspective factor values ​​are fused to output the thermal radiation perspective factor of each cabin subdomain. Based on the various thermal radiation perspective factors, a perspective factor matrix is ​​constructed to obtain the thermal flow radiation equation of the global thermal dynamics model. The perspective factor matrix is ​​then substituted into the thermal flow radiation equation for coupled solution to obtain the real-time temperature energy distribution field of the open-body barge cabin.

[0015] Furthermore, in a preferred embodiment of the present invention, step S03 specifically includes the following steps: A thermodynamic phase space architecture is constructed. By extracting the continuous real-time temperature and dynamic sequence of the open barge cabin within a preset time period from the real-time temperature and energy distribution field, the continuous real-time temperature and dynamic sequence is embedded into the thermodynamic phase space architecture for reconstruction, resulting in a series of temperature and dynamic vector links. The heat dissipation management criteria of the open-hull barge are obtained, and the thermal temperature steady-state index of the open-hull barge cabin is extracted through the heat dissipation management criteria. At the same time, the similarity between two adjacent temperature dynamic vector links is calculated to obtain multiple vector similarities. The system acquires a real-time acquisition strategy for multi-source heat-related data from the shipborne Internet of Things (IoT) and a dynamic update time slot for the acquisition order. An entropy order window is constructed based on the real-time acquisition strategy, and a time sequence maintenance step size is preset based on the dynamic update time slot. By using the thermal temperature steady-state index to maintain the step size along the time sequence, the vector similarity slides to the corresponding entropy order window. The conditional probability control points describing the stable and orderly evolution of thermal temperature for each vector similarity are calculated and fitted to generate the real-time steady-state approximate entropy curve of the open barge cabin temperature. Based on big data, the empirical steady-state approximate entropy curve of the open barge cabin under multi-source thermal correlation data is obtained, and the peak approximate entropy of the real-time steady-state approximate entropy curve is extracted and defined as the first approximate entropy peak value; and the peak approximate entropy of the empirical steady-state approximate entropy curve is obtained and defined as the second approximate entropy peak value. If the peak value of the first approximate entropy is greater than the peak value of the second approximate entropy, then the temperature of the open barge cabin is marked as a high-temperature runaway anomaly.

[0016] The beneficial technical effects of this invention are as follows: By installing air intake and exhaust pipes at the top of the hull and configuring fans at the bottom to form a forced convection ventilation path, compared with the traditional natural ventilation method that simply relies on opening the hatch, the air circulation efficiency of the hull can be significantly improved, enabling the rapid discharge of heat and toxic and harmful gases, thereby effectively reducing the working temperature inside the hull (by about 10°C or more). At the same time, the system has a simple structure, low modification cost, and convenient construction, and is suitable for rapid implementation in environments with limited resources. It can not only reduce engine power loss and mechanical wear caused by high temperature and reduce fuel consumption, but also significantly improve operational safety and equipment stability, avoiding the risk of poisoning or explosion caused by high temperature and accumulation of harmful gases. This ensures that the open-hull barge can operate efficiently, continuously, and safely under complex working conditions and throughout the year's construction window. Attached Figure Description

[0023] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0024] like Figures 1-4 As shown, the first aspect of the present invention provides a high-efficiency heat dissipation system for heavy-tonnage open-hull barges, the device including heat dissipation openings 101.

[0025] Two heat dissipation openings 101 are provided. One of the heat dissipation openings is an air intake opening, which can be opened at any position according to the layout requirements of the open-body barge deck. The other heat dissipation opening is an exhaust opening, which is set on the open-body barge deck near the cabin, and the distance between the exhaust opening and the cabin is 20cm. The diameter of the air intake opening and the exhaust opening is the same, and the diameter is set to 35cm.

[0026] An intake pipe column 102 is installed directly above the intake opening, and an exhaust pipe column 103 is installed at the top of the exhaust opening. Both the intake pipe column 102 and the exhaust pipe column 103 are made of steel pipe, and the inner diameter of the pipe column is uniformly set to 36cm.

[0027] The top of the intake pipe column 102 and the exhaust pipe column 103 are equipped with a waterproof cover 104. The waterproof cover 104 is also made of steel pipe material with a thickness of 5mm. Multiple auxiliary steel bars 105 arranged in a ring are welded to one end of the inner wall of the waterproof cover 104. The other end of the auxiliary steel bars 105 is welded to the side wall of the intake pipe column 102 and the exhaust pipe column 103.

[0028] Cooling fans 106 are installed at the bottom of both the air intake and exhaust vents. The cooling fans 106 are square-structured open-body barge power supply matching models, and the length and width of the cooling fans 106 are both 40cm.

[0029] It should be noted that this cooling system, by installing steel intake pipes 102 and exhaust pipes 103 of uniform inner diameter above the cooling opening 101, features a simple layout, convenient construction, and low cost. On one hand, it can orderly exhaust high-temperature air, effectively reducing the cabin temperature, improving the engine intake and operating environment, and reducing equipment failures and energy consumption. On the other hand, it can promptly disperse toxic and harmful gases, preventing poisoning of ship personnel and ensuring the safety of open-hull barge operations. The intake pipes 102 and exhaust pipes 103, combined with a waterproof cover 104 and internal auxiliary steel bars 105, form a ring-shaped reinforcement structure, ensuring the stability of the ventilation path and structural strength, and effectively preventing rainwater backflow, thus improving the cooling safety of the open-hull barge. A cooling fan 106, matched to the ship's power supply, is arranged at the bottom of the cooling opening 101, forming a forced ventilation system with active air supply and exhaust working in tandem, causing orderly airflow within the cabin, thereby significantly improving ventilation efficiency and heat dissipation capacity.

[0030] Furthermore, in a preferred embodiment of the present invention, bolt anchoring holes are provided around the location of the air intake opening on the open barge deck for fixing the cooling fan 106.

[0031] Furthermore, in a preferred embodiment of the present invention, the diameter of the bolt anchoring hole is 5mm, and four bolt anchoring holes are reserved at each heat dissipation opening.

[0032] Furthermore, in a preferred embodiment of the present invention, both the intake manifold 102 and the exhaust manifold 103 are connected to the deck of the open-hull barge by full welding.

[0033] Furthermore, in a preferred embodiment of the present invention, an exhaust hole 107 is provided at the top of the pipe of the intake pipe column 102 and the exhaust pipe column 103, which is toothed, and the opening depth of the exhaust hole 107 is 20cm.

[0034] It should be noted that this heat dissipation system, by setting serrated exhaust holes 107 at the top of the intake pipe column 102 and the exhaust pipe column 103, and opening the exhaust holes 107 to an effective depth of 20cm, can increase the gas exchange cross-sectional area without significantly weakening the overall structural strength of the pipe column. This allows the air inside the pipe to be dispersed and discharged or introduced in multiple directions at the top, avoiding airflow obstruction and backflow caused by a single opening. On the other hand, the serrated structure helps to reduce the impact of external wind pressure disturbance on airflow stability, improve the continuity and uniformity of exhaust and intake, and thus further enhance the air convection effect in the cabin.

[0035] Furthermore, in a preferred embodiment of the present invention, the cooling fan 106 is connected and fixed by four 5mm bolts and bolt anchor holes.

[0036] This high-efficiency heat dissipation system operates by simultaneously activating two cooling fans 106 when the open-hull barge cabin is in a high-temperature, high-heat environment. At this time, the cooling fans 106 at the bottom of the intake pipe column 102 generate air suction force, drawing air from outside the open-hull barge into the intake pipe column 102. The air then passes through the intake pipe column 102 and the air intake opening into the interior of the open-hull barge cabin, allowing the outside air to convect and mix with the high-temperature air inside the cabin. This further neutralizes and cools the high-temperature air inside the cabin and reduces the concentration and temperature of exhaust pollutants (such as hydrogen sulfide, carbon monoxide, nitrogen monoxide, sulfur dioxide, etc.) from point source pollutants (such as high-power diesel engines). At the same time, it improves the aerodynamic activity of high temperature and pollutant components, reducing the high-temperature effect of the open-hull barge. When the outside air mixes with the hot air and polluted exhaust gas inside the cabin, the cooling fan 106 below the exhaust pipe column 103 rotates and draws the hot air out of the exhaust opening. The air is then forced out of the cabin of the open-hull barge through the exhaust pipe column 103, achieving the effect of circulating air cooling and exhaust gas pollution emission. This helps the open-hull barge cabin to dissipate heat quickly and efficiently, significantly improving heat dissipation efficiency.

[0037] The second aspect of this invention provides a heat dissipation method for a high-efficiency heat dissipation system for a heavy-tonnage open-hull barge, applicable to any of the high-efficiency heat dissipation systems for heavy-tonnage open-hull barges described in any one of the claims, specifically including the following steps: S01: Obtain the thermal energy point sources of the open-hull barge cabin, construct the distributed thermal coupling nodes of the thermal energy point sources and the space cabin heat exchange model, analyze the spatial thermal coupling effect of the thermal energy point sources on the cabin using multi-source thermal correlation data, and couple the dynamic thermal energy conditions of each distributed thermal coupling node in the space cabin heat exchange model based on the spatial thermal resistance topology of the spatial thermal coupling effect to generate a global thermal dynamic model of the open-hull barge cabin. S02: The cabin sub-domains of the open-hull barge are divided by the layout of the power facility units of the open-hull barge. Based on the predetermined tolerance parameters of the power facility units to high temperature thermal energy, the observation perspective factor of the critical response thermal radiation of each cabin sub-domain is calculated. The observation perspective factor is substituted into the global energy dynamic model for coupled solution to obtain the real-time temperature energy distribution field of the open-hull barge cabin. S03: Extract temperature dynamic vector data of the open barge cabin based on the real-time temperature energy distribution field, analyze the thermal temperature trend stability of the open barge cabin through continuous vector similarity analysis of the temperature dynamic vector data, obtain real-time steady-state approximate entropy information, and perform peak analysis on the real-time steady-state approximate entropy information based on the approximate entropy information of thermal runaway to determine the high temperature runaway anomaly of the open barge cabin. S04: When the open-hull barge cabin experiences an abnormal high temperature runaway, the cooling fan will be activated to quickly expel the high-temperature air from the open-hull barge cabin through the exhaust vents and exhaust pipe, thereby rapidly cooling the interior of the open-hull barge cabin.

[0038] Furthermore, in a preferred embodiment of the present invention, step S01 specifically includes the following steps: The heat energy point sources of the open-hull barge are obtained, and the dynamic heat energy conditions of each heat energy point source during the predetermined time period are collected through the shipborne Internet of Things. Obtain a schematic diagram of the heat dissipation channels for each heat source located in the open-hull barge cabin through the heat dissipation management log, and establish distributed thermal coupling nodes for the heat sources based on the heat dissipation channel schematic diagram. Analyze the potential thermal state changes under dynamic thermal energy conditions, define the thermal energy emission amplitude of different distributed thermal coupling nodes, and simultaneously acquire the structural design drawings of the open barge cabin and multi-source thermal correlation data of the heat released towards the open barge cabin under the premise of dynamic thermal energy conditions of each thermal energy point source. The multi-source thermal correlation data includes cabin air temperature, cabin temperature-pressure difference, indoor temperature rise amplitude, temperature rise gradient, indoor temperature rise rate, heat flow direction, and convective wind speed. Introducing the theory of heat energy transfer, a space heat exchange model of the open barge cabin is constructed based on the structural design drawings. Based on the theory of heat energy transfer as the distribution criterion, the spatial thermal coupling effect of each heat energy point source on the open barge cabin is calculated using multi-source heat correlation data, and the spatial thermal coupling effect coefficient of each heat energy point source is obtained. Based on the space thermal coupling effect coefficient, a topology calculation is performed on the space cabin heat exchange model and the distributed thermal coupling nodes to generate a space thermal resistance network of open barge cabin-heat energy point source. Based on the thermal energy emission amplitude, a spatial thermal resistance network is used to establish and solve the thermal energy balance equation for each distributed thermal coupling node, thereby obtaining the dynamic heat exchange degree of the thermal energy point source. All the dynamic heat exchange degrees are spatiotemporally coupled to generate a global thermodynamic model of the open-body barge cabin.

[0039] It should be noted that due to the numerous operating devices within the cabins of open-hull barges, such as high-powered diesel engines and electrical control cabinets, these devices continuously generate a large amount of heat energy during prolonged operation. This heat energy accumulates within the open-hull barge, resulting in a consistently high-temperature environment within the cabins. Traditional technologies for real-time temperature monitoring typically use temperature sensors and the Internet of Things (IoT) to read global parameters and perform static threshold analysis within the open-hull barge cabins. However, these technologies struggle to quantify the dynamic contribution, transmission path, and cumulative effect of the heat energy output from different heat source operating devices within the cabins in creating the overall high-temperature environment. Consequently, they cannot accurately capture the local energy effects and dynamic changes of the high-temperature potential field, potentially leading to spatial blind spots, uneven heat dissipation, or the inability to eliminate localized hotspots during subsequent cabin cooling. To address this, this method collects dynamic thermal energy conditions during the operation of each thermal energy source. These sources include high-power diesel engines, generator sets, transformers, shipboard electrical distribution cabinets, hydraulic pumps, air compressors, and heat exchangers. Dynamic energy conditions represent the entire operational state of the thermal energy source over time, encompassing input, conversion, loss, and output. Examples include fuel input, electrical input, mechanical work heat, and frictional heat. These conditions serve as the basis for quantitative analysis of thermal energy coupling. Next, distributed thermal coupling nodes are established based on the heat dissipation channel diagrams of each thermal energy source. Since the spatial orientation and airflow direction of different operating equipment within the open-hull barge cabin vary, the heat dissipation paths and vectors of different thermal energy sources are not shared or universal. Therefore, the coupling points of the high-temperature environment within the cabin belong to a finite discrete state. Consequently, a distributed thermal coupling node is assigned to each thermal energy source, providing the base point for the dynamic coupling network from local temperature to the overall situational field. Furthermore, by analyzing the potential changes in the thermal state under dynamic thermal energy conditions, the variables of the entire process from the generation of thermal energy from different thermal energy point sources to its absorption by the air and then to its diffusion are clarified. The thermal energy emission amplitude abstractly depicts the heat transfer chain and actual transfer situation of different distributed thermal coupling nodes, providing a realistic digital expression and real-time variable index that conforms to the description of the high temperature environment inside the cabin for global thermal energy dynamic modeling.

[0040] It should be noted that by constructing a spatial heat exchange model of the open-hull barge cabin, this model anchors the three-dimensional thermal scalar field of the cabin. This model can accurately respond to and quantify the real-time temperature transfer and heat exchange parameters and their linear dynamic changes within the cabin space, making the dynamic visualization of global energy more accurate and stable. Subsequently, based on multi-source thermal correlation data and the theory of thermal energy transfer, the spatial thermal coupling effect of each heat source is calculated. This allows the determination of the coupling distribution ratio of heat energy transferred locally from the heat source to the cabin space. The spatial thermal coupling effect coefficient concretely illustrates the connection strength between the open-hull barge cabin and the heat source, revealing the direct thermal radiation share and exchange weight of the operating equipment within the cabin, making the parameterized display of global thermal energy more reasonable and accurate. Furthermore, by utilizing the space thermal coupling effect coefficient topology calculation of the space capsule heat exchange model and distributed thermal coupling nodes, the heat energy input and exchange process is equivalent to a topological network structure composed of "local point source thermal resistance" and "space thermal resistance," i.e., a space thermal resistance network. This effectively transforms the abstract data of nonlinear and directional heat transfer into a quasi-linear dynamic heat transfer process, constraining and guiding the correctness of the coupled modeling. Finally, the space thermal resistance network is used to establish and solve the heat energy balance equation for each distributed thermal coupling node based on the heat energy emission amplitude. This establishes a balance relationship between heat energy input and output for each heat energy point source from the perspective of energy conservation, achieving real-time data visualization of thermal dynamics. Compared with traditional heat dissipation technologies, the global thermal dynamic model of this method can describe the dynamic trend of heat energy, accurately determine the main heat accumulation areas, help identify local overheating and high-temperature risk points, and significantly improve heat dissipation efficiency.

[0041] Furthermore, in a preferred embodiment of the present invention, step S02 specifically includes the following steps: Obtain the hull dynamic layout diagram of the open-hull barge, obtain the power facility units of the open-hull barge hull through the hull dynamic layout diagram, and divide the open-hull barge hull into N hull subdomains according to the topological deployment of the power facility units. Obtain the model and specification information of the power facility unit, and retrieve the subcritical tolerance range of thermal energy for each power facility unit under different high temperature environmental conditions based on big data retrieval of the model and specification information; The limiting radiation boundary of each cabin subdomain is discretized into several thermal response infinitesimal integrals. The thermal response infinitesimal integrals are observed and weighted based on the radiation sensing of the subcritical tolerance range to generate the thermal radiation observation weight of each thermal response infinitesimal integral. The thermodynamic finite element algorithm is introduced to calculate the perspective scale of the thermal radiation observation weight, and the observation perspective factor value of each thermal response infinitesimal integral is obtained. According to the thermal radiation law, all observation perspective factor values ​​are fused to output the thermal radiation perspective factor of each cabin subdomain. Based on the various thermal radiation perspective factors, a perspective factor matrix is ​​constructed to obtain the thermal flow radiation equation of the global thermal dynamics model. The perspective factor matrix is ​​then substituted into the thermal flow radiation equation for coupled solution to obtain the real-time temperature energy distribution field of the open-body barge cabin.

[0042] It should be noted that the heat emitted by various operating equipment inside the cabin can easily exceed the normal operating temperature of the heat-sensitive components of various power equipment within the cabin due to excessively high temperatures, leading to a significant increase in the probability of equipment failure. Current technologies for judging cabin temperature distribution still rely on human experience and prior information-guided decision-making, failing to quantify heat radiation from the perspective of power equipment malfunctions. This can easily lead to detection errors and prediction deviations due to uncertainties and inconsistencies in temperature change assessment, reducing the accuracy of heat dissipation. To address this, this method first discretizes the cabin space into several heat radiation sensing domains, i.e., individual cabin subdomains, based on the layout structure of the power facility units within the open-hull barge cabin. Each cabin subdomain provides the power facility unit with an abstract sensing space and perspective capability that independently responds to heat radiation effects. Since the mechanical mechanisms, heat-sensitive components, or auxiliary transmission media within different power facility units have their own specific melting point criticalities and high-temperature resistance criticalities, exceeding these criticalities will lead to the failure and damage of these components. Therefore, these criticalities can serve as a angular factor for sensing high-temperature change trends. Therefore, this method decomposes the limiting radiation boundary of each subdomain into several thermal response integrals, thereby transforming the complex thermal radiation sensing mechanism of the power facility unit into a factor binding of the thermal radiation response from a high-temperature perspective. This enables fine-grained sensing of the threat of different local thermal radiation points within the cabin space. Furthermore, by using radiation sensing within the subcritical tolerance range to weight each thermal response integral, each subdomain is endowed with the ability to observe thermal radiation and anchor the high-temperature trend benchmark from the constraint angle of the subcritical tolerance threshold. Finally, the thermal radiation perspective factor for each subdomain is calculated based on the thermal radiation observation weights. This factor effectively measures the thermal radiation contribution of the cabin's high-temperature environment system to each power equipment unit, thus extracting the energy distribution term of the high-temperature system from the self-observation perspective of the safe operation of the power equipment unit.

[0043] Furthermore, in a preferred embodiment of the present invention, step S03 specifically includes the following steps: A thermodynamic phase space architecture is constructed. By extracting the continuous real-time temperature and dynamic sequence of the open barge cabin within a preset time period from the real-time temperature and energy distribution field, the continuous real-time temperature and dynamic sequence is embedded into the thermodynamic phase space architecture for reconstruction, resulting in a series of temperature and dynamic vector links. The heat dissipation management criteria of the open-hull barge are obtained, and the thermal temperature steady-state index of the open-hull barge cabin is extracted through the heat dissipation management criteria. At the same time, the similarity between two adjacent temperature dynamic vector links is calculated to obtain multiple vector similarities. The system acquires a real-time acquisition strategy for multi-source heat-related data from the shipborne Internet of Things (IoT) and a dynamic update time slot for the acquisition order. An entropy order window is constructed based on the real-time acquisition strategy, and a time sequence maintenance step size is preset based on the dynamic update time slot. By using the thermal temperature steady-state index to maintain the step size along the time sequence, the vector similarity slides to the corresponding entropy order window. The conditional probability control points describing the stable and orderly evolution of thermal temperature for each vector similarity are calculated and fitted to generate the real-time steady-state approximate entropy curve of the open barge cabin temperature. Based on big data, the empirical steady-state approximate entropy curve of the open barge cabin under multi-source thermal correlation data is obtained, and the peak approximate entropy of the real-time steady-state approximate entropy curve is extracted and defined as the first approximate entropy peak value; and the peak approximate entropy of the empirical steady-state approximate entropy curve is obtained and defined as the second approximate entropy peak value. If the peak value of the first approximate entropy is greater than the peak value of the second approximate entropy, then the temperature of the open barge cabin is marked as a high-temperature runaway anomaly.

[0044] It should be noted that current technologies still rely on manual experience and simple threshold comparisons to detect high-temperature anomalies in ship cabins. This undoubtedly increases the error component in high-temperature detection, leading to inaccurate temperature anomaly detection results, false alarms, and missed alarms. This results in delayed, slow, or false start-ups in heat dissipation response, seriously threatening the lives of personnel in the cabins. To address this, this method reconstructs the real-time temperature dynamic sequence describing the real-time temperature energy distribution field by constructing a thermodynamic phase space architecture. Since thermal runaway is not a single-point abrupt change but rather a divergence of orbits in the state space, the reconstruction of the temperature dynamic sequence can maximize the exposure of the periodicity, randomness, or chaos of the high-temperature vector, revealing and recovering the implicit dynamic structure of the cabin temperature environment distribution. Next, thermal temperature steady-state indices are extracted from the open-hull barge cabins using heat dissipation management criteria. These indices include the average cabin temperature, peak temperature, ambient temperature around equipment, and temperature uniformity coefficient. These thermal temperature steady-state indices can be used to quantitatively describe and evaluate the trend stability performance of temperature dynamics. Simultaneously, the vector similarity between two adjacent temperature dynamic vector links is calculated. Vector similarity measures whether the evolution patterns are similar across different time segments, establishing a criterion for judging local structural similarity and effectively distinguishing between regular and random behavior. Notably, if the vector similarity is greater than a preset similarity threshold, it indicates that the real-time temperature change trend of the open-hull barge's cabin is stabilizing; conversely, it indicates increased continuous fluctuations and low stability in the real-time temperature change trend, potentially indicating a risk of near-runaway. Since thermal temperature runaway is an evolutionary process rather than an instantaneous event, an entropy order window is constructed based on a real-time acquisition strategy of multi-source thermal correlation data. This entropy order window can capture abrupt changes or trend inflection points of continuous gradual increase. The preset time-series maintenance step size for dynamically updating time slots constrains the expansion of static entropy to a dynamic time-series evolution scale. Both of these factors inject temporal driving force into the dynamic entropy calculation of vector similarity.

[0045] It should be noted that the conditional probability control points describing the stable and orderly evolution of thermal temperature are calculated by the similarity of each vector. These conditional probability control points statistically represent the recurring anchor points of each stable temperature change in the overall sequence, indicating the frequency of occurrence of local temperature steady-state patterns. If the peak value of the first approximate entropy is greater than that of the second approximate entropy, it indicates that the real-time temperature trend is gradually moving towards uncontrolled order, and the orderliness of temperature changes is beginning to become chaotic, suggesting a risk of uncontrolled high-temperature anomalies in the current cabin. This method can capture and quantify the orderly steady-state changes of real-time temperature trends, amplify the chaos of high-temperature vectors, and capture the evolutionary trend from order to chaos before thermal temperature runaway. This allows for early detection of abnormal precursors to temperature runaway, providing a more sensitive and accurate high-temperature early warning mechanism for the heat dissipation response of open-hull barge cabins compared to traditional technologies, thus improving the reliability and timeliness of heat dissipation.
