[0002] Traditional seawater heat exchangers are mostly shell-and-tube heat exchangers. Specifically, the seawater heat exchanger is placed inside the engine room, and outside seawater is pumped into the heat exchanger to exchange heat with the heat source. However, currently common seawater heat exchangers have problems such as significant tube bundle vibration, numerous high-pressure seawater pipelines inside the engine room, obvious noise transmission paths, low safety and reliability, and high noise from the seawater pump. Summary of the Invention

[0003] This invention provides a heat dissipation and noise reduction structural component, a manufacturing method, a ship heat exchange system, and a ship, to solve the defects of existing seawater heat exchangers, such as numerous seawater pipelines, obvious noise transmission paths, poor safety and reliability, and high noise levels.

[0004] In a first aspect, the present invention provides a method for manufacturing a heat dissipation and noise reduction structural component.

[0005] An initial model of the heat dissipation and noise reduction structure is constructed based on the implicit function mathematical expression, which is:

[0006] f(x,y,z)=sin(ω1x)cos(ω1y)+sin(ω2y)cos(ω2z)+sin(ω3z)cos(ω3x)-C

[0007] In the formula, ω i The structural parameter represents the internal space shape of the heat dissipation and noise reduction structure, and C represents the gap parameter that controls the overall gap size of the heat dissipation and noise reduction structure.

[0008] Based on the heat exchange requirement, a first void parameter corresponding to the heat exchange requirement is calculated, and based on the noise reduction requirement, a second void parameter corresponding to the noise reduction requirement is calculated; a weighted average is calculated on the first void parameter and the second void parameter to obtain a weighted void parameter.

[0009] The obtained weighted void parameters are subjected to heat transfer performance and noise reduction performance assessments respectively. If both the heat transfer performance and the noise reduction performance meet the requirements, the current weighted void parameters are output. If either the heat transfer performance or the noise reduction performance does not meet the requirements, the first void parameter and the second void parameter are weighted and averaged again to obtain new weighted void parameters. The heat transfer performance and noise reduction performance assessments are then repeated until both meet the requirements.

[0010] Substituting the output weighted gap parameters into the implicit function mathematical expression, a mathematical model of the heat dissipation and noise reduction structure that meets the heat exchange and noise reduction requirements is obtained.

[0011] Heat dissipation and noise reduction structural components are printed using 3D printing technology according to the mathematical model.

[0012] According to a method for manufacturing a heat dissipation and noise reduction structural component provided by the present invention, the parameters for determining the heat transfer performance include heat transfer performance parameters and pressure drop; the steps for determining the heat transfer performance include:

[0013] Based on the weighted porosity parameters, the porosity of the heat dissipation and noise reduction structural components is calculated.

[0014] Based on the porosity, the heat transfer performance parameters and pressure drop corresponding to the current weighted void parameters are calculated;

[0015] If the obtained heat transfer performance parameters and pressure drop meet the heat transfer requirements, then the heat transfer performance of the current weighted void parameters is determined to meet the requirements.

[0016] According to the manufacturing method of a heat dissipation and noise reduction structural component provided by the present invention, the porosity corresponding to different porosity parameters is statistically analyzed to obtain the relationship between porosity and porosity parameters: D(C)=m1C 2 +m2C+m3

[0017] In the formula, D is the porosity, m i It is a constant;

[0018] Substituting the weighted void parameters, the porosity of the heat dissipation and noise reduction structure is obtained;

[0019] Based on the laws of flow heat transfer and Darcy's law, the relationships between heat transfer performance parameters and pressure drop with porosity are obtained as follows:

[0020] h(D) = n1D 2 +n2D=f(D)

[0021]

[0022] Where h is the heat transfer performance parameter, n i Where is a constant, Δp is the pressure drop, u is the flow velocity, μ is the viscosity of the medium, and k is the permeability;

[0023] Substituting the porosity values, we obtain the heat transfer performance parameters and pressure drop.

[0024] According to a method for manufacturing a heat dissipation and noise reduction structural component provided by the present invention, the noise reduction performance determination parameter includes sound insulation; the steps for determining the noise reduction performance include:

[0025] Based on the initial model of the heat dissipation and noise reduction structure, the selected structural parameters, and the weighted gap parameters obtained by weighted average calculation, the sound insulation of the heat dissipation and noise reduction structure is obtained.

[0026] If the sound insulation effect corresponding to the volume insulation meets the noise reduction requirements, then the noise reduction performance of the current weighted gap parameter is determined to meet the requirements.

[0027] According to a method for manufacturing a heat dissipation and noise reduction structural component provided by the present invention, the relationship between the void parameter and the sound insulation of the sound-absorbing heat exchange structure is obtained by measuring the sound insulation effect under different structures:

[0028] E=f(ω i C) = g(D)

[0029] Where E represents the sound insulation of the sound-absorbing heat exchange structure.

[0030] Substituting the weighted gap parameters into the relationship between the gap parameters and the sound insulation of the sound-absorbing heat exchange structure, the sound insulation of the heat dissipation and noise reduction structure is obtained.

[0031] Secondly, the present invention also provides a heat dissipation and noise reduction structural component, which is prepared by the manufacturing method of the heat dissipation and noise reduction structural component as described in the first aspect, wherein the heat dissipation and noise reduction structural component has a heat dissipation channel.

[0032] Thirdly, the present invention also provides a ship heat exchange system, including a hull, coolant piping, and a heat dissipation and noise reduction structure as described in the first aspect. The heat dissipation and noise reduction structure is embedded inside the hull wall of the hull. The hull has a coolant inlet and a coolant outlet, which are respectively located on opposite sides of the heat dissipation and noise reduction structure. One end of the coolant piping is connected to the coolant inlet, and the other end is connected to the coolant outlet.

[0033] According to a ship heat exchange system provided by the present invention, a coolant pump is installed on the coolant pipeline; and / or, an inlet valve is installed on the coolant inlet and an outlet valve is installed on the coolant outlet.

[0034] According to a ship heat exchange system provided by the present invention, the diameter of the heat dissipation channel on the side closer to the outside of the hull is larger than the diameter on the side closer to the inside.

[0035] Fourthly, the present invention also provides a ship, including the ship heat exchange system as described in the second aspect.

[0036] The present invention provides a heat dissipation and noise reduction structural component, a manufacturing method, a ship heat exchange system, and a ship. The heat dissipation and noise reduction structural component is installed inside the hull wall. The heat from the heat source is transported to the hull by the coolant along the coolant pipeline. Heat exchange is carried out with the help of the low temperature seawater outside the hull. Therefore, there is no need to set up a sea outlet and sea outlet pipeline in the hull, nor is there a need to set up a seawater pump. This eliminates the impact of the high noise of the seawater pump and improves the reliability and quietness of the entire ship. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] The following is combined Figures 1-6 The heat dissipation and noise reduction structure 10 of the present invention is described.

[0051] Specifically, such as Figure 1 As shown, the manufacturing method of the heat dissipation and noise reduction structural component includes:

[0052] Step S1: Construct an initial model of the heat dissipation and noise reduction structure based on the implicit function mathematical expression, wherein the implicit function mathematical expression is:

[0053] f(x,y,z)=sin(ω1x)cos(ω1y)+sin(ω2y)cos(ω2z)+sin(ω3z)cos(ω3x)-C(1)

[0054] Where, ω i The structural parameter represents the internal space shape of the heat dissipation and noise reduction structure, and C represents the gap parameter that controls the overall gap size of the heat dissipation and noise reduction structure.

[0055] Step S2: Calculate the first void parameter corresponding to the heat exchange requirement based on the heat exchange requirement; calculate the second void parameter corresponding to the noise reduction requirement based on the noise reduction requirement.

[0056] Step S3: Calculate the weighted average of the first and second void parameters to obtain the weighted void parameters; then, evaluate the heat transfer performance and noise reduction performance of the obtained weighted void parameters.

[0057] Step S4: If both heat exchange performance and noise reduction performance meet the requirements, output the current weighted void parameters. If either heat exchange performance or noise reduction performance does not meet the requirements, calculate the weighted average of the first void parameters and the second void parameters again to obtain new weighted void parameters, and re-judge the heat exchange performance and noise reduction performance until both meet the requirements.

[0058] Step S5: Substitute the output weighted gap parameters into the implicit function mathematical expression to obtain the mathematical model of the heat dissipation and noise reduction structure that meets the heat exchange and heat dissipation requirements.

[0059] Step S6: Print the heat dissipation and noise reduction structural components according to the mathematical model determined in step S5 using 3D printing technology.

[0060] Specifically, in step S1, an initial model of the heat dissipation and noise reduction structure is constructed based on the implicit function mathematical expression, selected structural parameters, and pore parameters. In this initial model, the minimum curvature of any surface is zero, and there are no flow inflection points, resulting in low resistance to fluid flow. Moreover, the initial model has a large specific surface area, which greatly increases the heat exchange area and significantly improves the heat exchange efficiency between cold and hot fluids.

[0061] In the implicit function mathematical expression (1), ω i C and C can be set according to actual needs. By setting the specific values ​​of the two parameters, the internal space shape and overall gap size of the heat dissipation and noise reduction structure can be controlled respectively.

[0062] In step S2, the first void parameter C1 and the second void parameter C2 need to be obtained according to the heat exchange requirements and noise reduction requirements of the actual application scenario.

[0063] For example, the parameters for determining heat exchange requirements include: heat transfer performance parameters and pressure drop. In other words, when the designed heat dissipation and noise reduction structure is applied to a real-world application scenario, the entire heat dissipation and noise reduction structure needs to have sufficient heat transfer performance parameters and pressure drop to achieve heat exchange.

[0064] After substituting the given first gap parameter C1 into the above implicit function mathematical expression (1), the resulting heat dissipation and noise reduction structure needs to meet the requirements of heat transfer performance parameters and pressure drop.

[0065] For example, the parameters for determining noise reduction requirements include sound insulation. In other words, when the designed heat dissipation and noise reduction structure is applied in a real-world application scenario, the entire structure needs to have sufficient sound insulation to achieve noise reduction.

[0066] In this embodiment, after substituting the given second gap parameter C2 into the above implicit function mathematical expression (1), the resulting heat dissipation and noise reduction structure needs to meet the sound insulation requirements.

[0067] However, the first gap parameter C1 and the second gap parameter C2 obtained above may only meet the heat exchange requirement or the noise reduction requirement. In order to make the heat dissipation and noise reduction structure designed meet both the heat exchange requirement and the noise reduction requirement, the first gap parameter C1 and the second gap parameter C2 need to be adjusted.

[0068] In response, in step S3, a weighted average function θ can be used to calculate the weighted average of the first gap parameter C1 and the second gap parameter C2 to obtain the weighted gap parameter C. i Then, using this weighted gap parameter C i The heat exchange performance and noise reduction performance were assessed separately.

[0069] For example, in one embodiment, the step of determining heat exchange performance includes:

[0070] Based on the initial model constructed from the implicit function mathematical expression, the selected structural parameters and the weighted void parameters obtained by weighted average calculation are used to obtain the porosity of the heat dissipation and noise reduction structural component.

[0071] Based on porosity, the heat transfer performance parameters and pressure drop corresponding to the current weighted porosity parameters are calculated;

[0072] If the obtained heat transfer performance parameters and pressure drop meet the user's heat exchange requirements, it means that the heat exchange performance of the current void parameters meets the requirements.

[0073] Furthermore, the porosity of the heat dissipation and noise reduction structural components is determined by the following method:

[0074] By statistically analyzing the porosity under different porosity parameters, the relationship between porosity and porosity parameters can be obtained:

[0075] D(C)=m1C 2 +m2C+m3(2)

[0076] In the formula, D is the porosity, C is the porosity parameter, and m i It is a constant.

[0077] In other words, given the structural parameters, we first need to use an initial model constructed based on implicit function mathematical expressions to obtain the corresponding porosity D under multiple different values ​​of the pore parameter C. Then, using the obtained numerical relationships, we can construct a mathematical model to obtain the relationship between the pore parameter C and the porosity D (2). It can be understood that each pore parameter C corresponds to a porosity D.

[0078] Furthermore, methods for determining heat transfer performance parameters and pressure drop include:

[0079] Based on the laws of flow heat transfer and Darcy's law, the relationships between heat transfer performance parameters and pressure drop with porosity are obtained as follows:

[0080] h(D) = n1D 2 +n2D=f(D)(3)

[0081]

[0082] Where h is the heat transfer performance parameter, n i is a constant, Δp is the pressure drop, u is the flow velocity, μ is the viscosity of the medium, and k is the permeability.

[0083] In this embodiment, heat transfer performance parameters and pressure drop can be obtained based on the porosity.

[0084] Understandably, each void parameter corresponds to a porosity, and each porosity corresponds to a heat transfer performance parameter and a pressure drop. After obtaining the void parameters, the corresponding heat transfer performance parameters and pressure drop can be obtained. Then, based on the heat transfer performance parameters and pressure drop given the heat transfer requirements, it can be determined whether the current void parameters meet the heat transfer requirements.

[0085] For example, the parameters for determining noise reduction requirements include sound insulation. Therefore, it is necessary to determine whether the designed structure meets the noise reduction requirements based on the sound insulation.

[0086] In this embodiment, the steps for determining the noise reduction performance include:

[0087] Based on the gap parameters, the sound insulation of the heat dissipation and noise reduction structure is obtained; if the obtained sound insulation meets the sound insulation requirements, it means that the sound insulation performance of the current gap parameters meets the requirements.

[0088] Specifically, in the design method of this embodiment, the relationship between the void parameters and the sound insulation of the heat dissipation and noise reduction structural components is obtained through the deformation relationship under different structures:

[0089] E=f(ω i C)=g(D) (5)

[0090] Where E represents the sound insulation amount for noise reduction and heat transfer.

[0091] It is understandable that, given a fixed structural parameter, the relationship between the above-mentioned void parameter and the sound insulation can be obtained by using the initial model constructed based on the implicit function mathematical expression and the deformation relationship under different structures (5).

[0092] Since the sound insulation value is included in the parameters for determining the sound attenuation requirement, the sound insulation value obtained by using the void parameters can be compared with the sound insulation value in the determination parameters to determine whether the current weighted void parameters meet the sound attenuation requirement.

[0093] In this embodiment, in step S3, after substituting the obtained weighted void parameters into the above expressions (3), (4), and (5), it can be determined whether the current weighted void parameters meet the parameters given for heat exchange and noise reduction requirements.

[0094] Furthermore, in step S4, if the heat transfer performance and noise reduction performance both meet the requirements under the current weighted void parameters, it means that the heat dissipation and noise reduction structure designed based on the current weighted void parameters meets the design requirements. At this time, the weighted void parameters can be output.

[0095] If, under the current weighted void parameters, at least one of the heat transfer performance and noise reduction performance does not meet the requirements, it indicates that the heat dissipation and noise reduction structure designed based on the current weighted void parameters has defects. In this case, it is necessary to recalculate the first void parameters and the second void parameters using different weighted averaging methods to obtain new weighted void parameters. Then, substitute the new weighted void parameters into the above expressions (3), (4), and (5) respectively to continue the calculation and judgment until the weighted void parameters that meet both heat transfer performance and noise reduction performance are finally obtained.

[0096] Finally, in step S5, the output weighted gap parameters are substituted into the implicit function mathematical expression, thereby obtaining the mathematical model of the heat dissipation and noise reduction structure that meets the requirements.

[0097] In step S6, the heat dissipation and noise reduction structural component 10 is prepared using 3D printing technology. It is made by printing powdered metal layer by layer based on a digital model.

[0098] This invention provides a heat dissipation and noise reduction structure 10, such as... Figure 2 As shown, the heat dissipation and noise reduction structure 10 is manufactured using the manufacturing method described above.

[0099] Among them, such as Figure 2As shown, the heat dissipation and noise reduction structure 10 is a three-dimensional skeleton structure. This structure has heat dissipation channels 11, which are channels or cavities within the skeleton. The minimum curvature of any surface in the solid portion of the heat dissipation and noise reduction structure 10 is zero. The solid portion of the heat dissipation and noise reduction structure 10 refers to the wall surface of the heat dissipation channel 11. Because the minimum curvature of any surface in the solid portion of the heat dissipation and noise reduction structure 10 is zero, the wall surface of the heat dissipation channel 11 in the entire heat dissipation and noise reduction structure 10 is smooth, with no flow inflection points, resulting in low resistance. Therefore, when the coolant flows within the heat dissipation channel 11, it does not generate significant noise. Furthermore, by setting the heat dissipation channel 11 within the heat dissipation and noise reduction structure 10 to ensure that the minimum curvature of any surface on the structure is zero, the specific surface area of ​​the entire heat dissipation and noise reduction structure 10 is increased, thereby increasing the heat exchange area of ​​the coolant and improving heat exchange efficiency.

[0100] Taking the heat dissipation of heat source 30 inside the ship as an example, traditional heat exchangers require at least two pipelines for heat exchange: one for coolant to carry away heat from heat source 30; and the other for seawater to act as a heat exchange pipeline, used to lower the temperature of the coolant in the coolant pipeline, thus cooling the coolant and preparing it for the next cycle. Figure 3 As shown, when the heat dissipation and noise reduction structure 10 provided by the present invention is used, the heat dissipation and noise reduction structure 10 is set inside the shell wall of the hull 20. The heat from the heat source 30 is transported to the hull 20 by the coolant along the coolant pipeline, and heat exchange is carried out with the help of the low temperature seawater outside the hull 20. Therefore, it is not necessary to set up a sea outlet and sea outlet pipeline in the hull 20, nor is it necessary to set up a seawater pump, thereby eliminating the impact of the high noise of the seawater pump and improving the reliability and quietness of the entire ship.

[0101] This invention also provides a ship heat exchange system, such as... Figure 3 As shown, the ship's heat exchange system includes a hull 20, coolant piping, and a heat dissipation and noise reduction structural component 10 as described above. The heat dissipation and noise reduction structural component 10 is embedded inside the hull wall of the hull 20. Figure 4 As shown, the hull 20 is provided with a coolant inlet 21 and a coolant outlet 22, which are respectively located on opposite sides of the heat dissipation and noise reduction structure 10. One end of the coolant pipeline is connected to the coolant inlet 21, and the other end is connected to the coolant outlet 22.

[0102] The dimensions of the heat dissipation and noise reduction structural component 10 are adapted to the internal dimensions of the shell wall of the compartment 20. Based on the location of the heat source 30 and the arrangement of the coolant piping, a coolant inlet 21 and a coolant outlet 22 are provided on the compartment 20. The heat dissipation and noise reduction structural component 10 is inserted into the compartment 20 and fixed to the shell wall of the compartment 20 by welding or other methods. As the coolant flows from the coolant inlet 21 to the coolant outlet 22, it flows along the heat dissipation channel 11. Utilizing the large specific surface area and smooth wall surface of the heat dissipation and noise reduction structural component 10, noise is reduced and heat exchange efficiency is improved.

[0103] The heat source 30 is located inside the cavity formed by the hull 20. The coolant pipeline passes through the heat source 30, transferring heat from the heat source 30 to the coolant. The heated coolant flows into the hull 20 along the coolant pipeline. When the coolant flows from the coolant inlet 21 to the coolant outlet 22, the heated coolant exchanges heat with the low-temperature seawater outside the hull 20. The cooled coolant is discharged from the coolant outlet 22 and flows back to the heat source 30.

[0104] like Figure 5 The image shown is a comparison of the heat dissipation effect of the ship heat exchange system provided by this invention and a traditional plate-fin heat exchanger. From... Figure 5 As can be seen, at the same Reynolds number (horizontal axis Re), the heat dissipation effect of the ship heat exchange system provided by the embodiments of the present invention is significantly higher than that of the traditional plate-fin heat exchanger.

[0105] like Figure 6 As shown, the ship heat exchange system provided by this invention generates less than 40 decibels of noise during use, which is a significant improvement compared to the noise of seawater pumps.

[0106] The ship heat exchange system provided in this embodiment of the invention sets the heat dissipation and noise reduction structure 10 as described above inside the shell wall of the hull 20. It eliminates the need for sea outlets and sea pipelines in the hull 20, as well as seawater pumps, thereby reducing noise, improving heat exchange efficiency, and enhancing the reliability and quietness of the ship.

[0107] like Figure 3 As shown, a coolant pump 40 is installed on the coolant pipeline; and / or, an inlet valve 51 is installed on the coolant inlet 21, and an outlet valve 52 is installed on the coolant outlet 22.

[0108] A coolant pump 40 is installed at the coolant outlet 22 to improve the flow of coolant. An inlet valve 51 is installed at the coolant inlet 21 and an outlet valve 52 is installed at the coolant outlet 22. By controlling the outlet valve 52 and the inlet valve 51, the flow rate of coolant can be adjusted to meet the cooling requirements of different equipment.

[0109] like Figure 3As shown, there are two heat sources 30. The coolant pipes of the two heat sources 30 are connected to the coolant inlet 21 through a tee pipe, or they are first combined into one line and then connected to the coolant inlet 21.

[0110] Specifically, the diameter of the heat dissipation channel 11 on the side closer to the outside of the housing 20 is larger than the diameter on the side closer to the inside.

[0111] That is, the heat dissipation channel 11 of the heat dissipation and noise reduction structure 10 near the seawater has a large diameter, and when the coolant flows along the heat dissipation channel 11 in the heat dissipation and noise reduction structure 10, the flow rate is faster and the heat exchange capacity is stronger.

[0112] In addition, embodiments of the present invention also provide a ship, including the ship heat exchange system described above.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
