Description

Technical Field

[0001] This invention belongs to the field of thermal control technology for electronic devices, and specifically relates to an active front-end component structure for integrated composite heat dissipation. Background Technology

[0002] With the continuous development and progress of science and technology, the trend of electronic products towards high performance and miniaturization has become increasingly prominent. The high integration of electronic devices has led to an exponential increase in the heat flux density of these products. Overheating has become one of the main causes of electronic product failure, severely impacting the reliability and lifespan of electronic equipment. Since device reliability is highly sensitive to temperature, the development of heat dissipation technology is a crucial element in the trend towards high reliability, high performance, and high integration in electronic equipment. Military electronic equipment, due to the special nature of its operating environment, has even more stringent requirements for heat dissipation, with active front-end components being the most representative example.

[0003] Active front-end components are a core part of radar seekers. To achieve high performance and multifunctionality, a large number of high-power heat-generating components are typically integrated into the active front-end components, some of which are highly sensitive to temperature. With the increasing integration of active front-end components, the heat dissipation problems caused by high heat flux density and limited heat dissipation space are becoming increasingly prominent.

[0004] Currently adopted heat dissipation measures mainly include the following categories: natural cooling (mostly using natural air convection), forced convection cooling (including air cooling and liquid cooling), and thermoelectric cooling. Their thermal design usually draws on past design experience, resulting in significant limitations in design thinking. To meet heat dissipation requirements, large margins are often left, leading to either bloated overall equipment and a large system, or the inability to meet the system's heat dissipation requirements at all. Furthermore, they result in long production cycles, high costs, and may even affect the implementation of the overall system plan.

[0005] Therefore, it is imperative to design an efficient and reliable heat dissipation device to ensure the reliable and stable operation of the radar seeker. Summary of the Invention

[0006] In response to one or more of the above-mentioned defects or improvement needs of the existing technology, the present invention provides an integrated composite heat dissipation active front-end component structure.

[0007] To achieve the above objectives, the present invention provides an integrated composite heat dissipation active front-end component structure, the main structure of which, from top to bottom, includes a first heat-generating component, a cold plate component, a second heat-generating component, and a base.

[0013] As a further improvement of the present invention, the cavity of the heat storage module is designed with several uniformly distributed heat exchange teeth.

[0014] As a further improvement of the present invention, the cold plate assembly includes a cold plate box body and a cold plate cover plate. The cold plate box body is provided with a flow channel, and heat dissipation fins are uniformly distributed in the flow channel.

[0015] As a further improvement of the present invention, the pipe bending assembly includes a bent pipe and a straight pipe, wherein the bent pipe is connected to the cold plate assembly, one end of the straight pipe is connected to the bent pipe, and the other end is provided with a step that contacts the base; one side of the step is pressed onto the base by a pressure plate, and the other side is used to connect to a pipe fitting.

[0016] As a further improvement of the present invention, the connecting surface of the pipe bending assembly and the cold plate assembly is provided with a convex-concave interlaced structure, and an adhesive is applied or a sealing ring is provided at the convex-concave interlaced structure.

[0017] As a further improvement of the present invention, a shielding cylinder is provided on the outside of the main structure of the active front-end component. One end of the shielding cylinder is fixed on the first heating component, and the other end is fixed on the base.

[0018] As a further improvement of the present invention, thermally conductive pads are attached between the cold plate assembly and the first heating component, and between the cold plate assembly and the second heating component.

[0019] As a further improvement of the present invention, the first heating component, the cold plate component, the second heating component and the base are connected in sequence by screws. The connecting surfaces of the second heating component and the base are provided with a plurality of boss structures or groove structures, and the boss structures on two adjacent connecting surfaces match the groove structures.

[0020] In summary, the technical solutions conceived by this invention have the following beneficial effects compared with the prior art:

[0021] (1) The active front-end component structure of the integrated composite heat dissipation of the present invention forms an optimized closed heat flow path through the matching combination of cold plate component, heat storage module and heat generation component, which has the composite heat dissipation function of efficient heat transfer, energy storage heat absorption and working fluid heat dissipation, so as to meet the purpose of efficient heat dissipation of the missile-borne active front-end component; the heat dissipation of the active front-end component is achieved by absorbing a large amount of heat through the melting of phase change material, and the bending pipe component and pipe joint are provided to facilitate connection with external air pipe or liquid cooler, further realizing heat dissipation of the active front-end component for long-term testing.

[0022] (2) The active front-end component structure of the integrated composite heat dissipation of the present invention has a cold plate component and a heat storage module located between the first heating component and the first heating component. The heat generated by the two can be quickly transferred to the cold plate component and the heat storage module located in the middle part, and the heat is carried away by the working fluid flowing in the cold plate component, thereby reducing the temperature generated by the heating component and achieving the effect of efficient heat transfer.

[0023] (3) The active front-end component structure of the integrated composite heat dissipation of the present invention can avoid the long screws from bearing large shear forces by setting circular limiting steps on each component, and can increase the structural strength of the entire device while playing an electromagnetic shielding role by setting shielding cylinders on the outer contour of each component.

[0024] (4) The active front-end component structure of the integrated composite heat dissipation of the present invention can improve the structural strength and internal thermal conductivity of the heat storage module by designing uniformly distributed heat exchange teeth inside the heat storage module cavity, so that the heat storage module has high latent heat of phase change and thermal instantaneous response characteristics, which can satisfy the requirement that heat can be rapidly and uniformly diffused inside the heat storage module and absorbed by the phase change material in time, thereby achieving efficient and reliable heat storage.

[0025] (5) The active front-end component structure of the integrated composite heat dissipation of the present invention adopts a bent pipe component connected to a cold plate component, so that the interface of the flow channel is introduced into the bottom of the entire device. By replacing the plug of the bottom flow channel opening with a pipe connector, it can be connected to an external liquid cooler or air pipe, thereby realizing the connection of the cooling circulation loop of the cold plate component, thus achieving efficient heat dissipation and ensuring long-term testing of the active front-end component. The entire replacement process is relatively simple and convenient.

[0026] (6) The active front-end component structure of the integrated composite heat dissipation of the present invention has one end of the bent tube component connected to the cold plate component, and the other end is pressed and fixed by the pressure plate and the base, so that the bent tube component is fully constrained and the cantilever structure is avoided.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

Therefore, they should not be construed as limitations on this invention.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] Please see Figures 1 to 3 The integrated composite heat dissipation active front-end component structure of the present invention comprises, from top to bottom, a first heating component 1, a cold plate component 9, a second heating component 4, and a base 7. The first heating component 1 is preferably a TR component, used for signal transmission and reception. The cold plate component has internal flow channels. When the first heating component 1 and the second heating component 4 transfer the generated heat to the cold plate component, the heat is carried away by the working fluid (air or water) flowing inside, ensuring that the temperature of each heating component remains stable within the normal operating temperature range during long-term testing.

[0042] Specifically, the cold plate assembly 9 is located between the first heating component 1 and the second heating component 4. Thermally conductive pads 2 are preferably adhered between the cold plate assembly 9 and the first heating component 1, and between the cold plate assembly 9 and the second heating component 4, to reduce the thermal resistance between the heating components and the heat dissipation components and ensure the high efficiency of the heat transfer path. More preferably, the cold plate assembly 9 has limiting steps on both its upper and lower surfaces for adhering the thermally conductive pads 2, which serve a limiting function when the thermally conductive pads 2 are assembled and compressed.

[0043] The cold plate assembly 9 is connected to the bent pipe assembly 3. The bent pipe assembly 3 avoids the second heating assembly 4 and passes through the corresponding mounting hole on the base 7 and forms a corresponding interface at its bottom, serving as the inlet and outlet of the internal cooling medium of the cold plate assembly. It is used to connect with the corresponding pipe joint 8, which facilitates connection with external gas pipes or liquid coolers to form a closed-loop cooling system. This system satisfies the reliability of the heat dissipation performance of the active front end during long-term ground testing.

[0044] It should be noted that the pipe connector 8 is detachably connected to the bend assembly, and the two are sealed with a sealing ring. One end of the pipe connector 8 is connected to the active front-end assembly, and the other end is connected to the pipeline, which meets the requirements for long-term testing of the active front-end assembly and ensures the reliability of the component's heat dissipation performance. After the entire active front-end assembly has been tested on the ground, the pipe connector 8 can be removed and replaced with a plug, which is beneficial for the aesthetics of the entire active front-end assembly and the sealing of residual working fluid in the cooling system.

[0045] Specifically, such as Figure 4 As shown, the cold plate assembly 9 includes a cold plate housing 901, a cold plate cover 902, and heat sinks 903. The cold plate housing 901 and the cold plate cover 902 are preferably formed as a single unit by vacuum brazing. The cold plate housing 901 has internal flow channels with corresponding inlets and outlets. The flow channels contain uniformly distributed heat sinks 903. It is easy to understand that the uniformly distributed heat sinks within the flow channels can form natural flow paths, further increasing the flow path of the working fluid within the cooling system and increasing the heat exchange surface between the working fluid and the heat source, thereby improving the system's heat dissipation efficiency.

[0046] like Figure 5 As shown, the pipe bending assembly 3 is preferably made of stainless steel and includes a pipe bending 301 and a straight pipe 302. The pipe bending 301 is connected to the cold plate assembly 9. One end of the straight pipe 302 is connected to the pipe bending 301, preferably by welding. The other end of the straight pipe 302 is provided with a step, which contacts the base. One side of the step is pressed onto the base by a pressure plate 12, and a rubber plate is pasted between the two contact surfaces. The other side of the step is connected to the pipe joint 8, and the step surface is pressed by a sealing ring at the connection.

[0047] Based on the above design, the steps at one end of the straight pipe 302 are simultaneously clamped by force, ensuring the fixation of the end of the straight pipe 302 in the bending pipe assembly 3. The other end is fixedly connected to the cold plate assembly 9 via the bending pipe 301, so that the bending pipe assembly 3 is in a fully constrained state, avoiding the occurrence of cantilever structures.

[0048] Combination Figures 4 to 6 The two bent pipe assemblies 3 are respectively connected to the inlet and outlet of the cold plate assembly 9. Preferably, the connection surface between the bent pipe assembly 3 and the cold plate assembly 9 is provided with a convex-concave interlaced structure, and adhesive is applied and a sealing ring is set at the convex-concave interlaced structure to form a multi-seal structure, which can meet the sealing reliability requirements.

[0049] Further reading Figure 7The second heating component 4 of the present invention specifically includes a heat storage module, a power supply component, a signal processing board 403, and a heat-conducting block 406. The signal processing board 403 is mounted on the heat storage module; the power supply component includes a power board 405, a power module 407, and a power housing 408, with the power board 405 and power module 407 mounted on the power housing 408. A heat-conducting boss is provided between the signal processing board 403 and the heat storage module, and a heat-conducting block 406 is provided on the side of the signal processing board 403 facing away from the heat storage module. The heat-conducting block 406 is mounted between the signal processing board 403 and the power module 407, transferring the heat generated by the heating device on that side of the signal processing board 403 to the power module 407, and then from the power module to the base 7. A heat-conducting boss is provided between the power board 405 and the power housing 408, through which heat is discharged and transferred to the base 7.

[0050] Preferably, the high-power heat-generating devices on the signal processing board 403 and the power supply board 405 are all fitted with thermally conductive pads between themselves and their corresponding thermally conductive structural components to reduce thermal resistance and enable the heat generated by the heat-generating devices to be transferred to the structural components in a timely and effective manner.

[0051] Combination Figure 8 As shown, the thermal storage module includes a thermal storage box 401, a phase change material 402, and a thermal storage cover plate 404. The thermal storage box 401 and the thermal storage cover plate 404 are preferably formed as a single unit by vacuum brazing. The thermal storage module is designed with a filling port for injecting the phase change material 402. Specifically, the molten phase change material 402 is first injected into the cavity of the thermal storage module using a vacuum injection method, and then the filling port is sealed using friction stir welding.

[0052] In a preferred embodiment, the cavity of the thermal storage module is designed with several uniformly distributed heat exchange teeth. On the one hand, this can improve the thermal conductivity of the phase change material 402 inside the thermal storage module, and on the other hand, it can improve the overall structural strength of the thermal storage module to prevent the thermal expansion of the phase change material 402 inside the thermal storage module from causing structural deformation under low pressure conditions.

[0053] Preferably, the contact surface between the thermal storage module and the cold plate assembly 9 is designed with a stepped surface, which is used to limit the height direction when the thermal storage module and the cold plate assembly are attached to the thermally conductive pad and when the thermally conductive pad is compressed.

[0054] During long-term ground testing, the working fluid flowing in the cold plate assembly 9 carries away the heat generated by the system, ensuring reliable heat dissipation for long-term operation of the components. During flight testing, since the active front-end components are in a confined space and the cooling system cannot be used, the phase change material 402 inside the heat storage module absorbs heat to ensure the stability of the thermal performance of the active front-end components during short-term operation. That is, the heat generated by the heat-generating device is converted into latent heat of phase change. When the temperature reaches the melting point of the phase change material 402, the phase change material 402 changes from solid to liquid and absorbs heat violently, ensuring that the component temperature is controlled near the melting point.

[0055] The active front-end component of the integrated composite heat dissipation of the present invention includes a cold plate assembly and a phase change heat storage module, forming a closed and efficient heat dissipation link between the heat source and the cold plate. The thermal resistance of the entire system is reduced by using thermally conductive pads and improving the surface processing precision of structural components. The integrated composite heat dissipation of this active front-end component ensures reliable heat dissipation performance during both long-term testing and short-term flight.

[0056] Furthermore, a shielding cylinder 5 is provided on the outer side of the main structure of the active front-end component. One end of the shielding cylinder 5 is fixed to the first heating element 1, and the other end is fixed to the base 7. This serves two purposes: increasing the structural strength of the entire active front-end and providing electromagnetic shielding for the entire active front-end. The stepped surface at the top of the shielding cylinder 5 matches the stepped surface of the first heating element 1. A closed annular shielding strip 6 is added to the gap between the bottom of the shielding cylinder 5 and the base 7. The shielding strip 6 is compressed and deformed with fasteners to fill the gap, ensuring a seamless connection. The connection structure of the upper and lower end faces of the shielding cylinder 5 effectively improves the shielding effect of the active front-end. The shielding cylinder 5 is preferably made of stainless steel, and its thickness is preferably 2mm.

[0057] More preferably, the bottom of the shielding cylinder 5 is provided with a positioning notch to allow space and position the lugs of the base 7, ensuring the uniqueness of the assembly position of the shielding cylinder 5. In addition, the shielding cylinder is machined, and by controlling the machining precision, the fit between the shielding cylinder 5 and the active front-end body is improved, reducing electromagnetic leakage.

[0058] Preferably, the first heating component 1, the cold plate component 9, the second heating component 4, and the base 7 are sequentially stacked and connected by screws 10; more preferably, the connecting surfaces of the first heating component 1, the cold plate component 9, the second heating component 4, and the base 7 are provided with a plurality of boss structures or groove structures, and the boss structures on two adjacent connecting surfaces match the groove structures, which can play a positioning role on the one hand, and effectively prevent the screws 11 from bearing shear force on the other hand.

[0059] Preferably, the base 7 is provided with a mounting flange for fixing to the compartment, and the mounting flange is provided with pin holes for positioning the compartment, so as to ensure the installation accuracy of the entire active front-end assembly in the compartment.

[0060] The integrated composite heat dissipation active front-end component structure of this invention forms an optimized closed heat flow path through the matching combination of cold plate components, heat storage modules, and heat-generating components. It has a composite heat dissipation function that combines efficient heat transfer, energy storage and heat absorption, and working fluid heat dissipation to meet the purpose of efficient heat dissipation of missile-borne active front-end components. It achieves heat dissipation of active front-end components by absorbing a large amount of heat through the melting of phase change materials. At the same time, it is equipped with bent pipe components and pipe joints to facilitate connection with external air pipes or liquid coolers, further realizing heat dissipation for long-term testing of active front-end components.

[0061] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
