Description

Technical Field

[0001] This utility model belongs to the field of concentrator technology, and specifically relates to a modular and replaceable concentrator heat dissipation structure. Background Technology

[0002] With the development of information technology, the power consumption of data processing equipment such as routers, switches, and servers is constantly increasing, especially in high-performance computing (HPC) and cloud computing fields, where the heat generated by these devices is also increasing. To ensure the normal operation of these devices, effective heat dissipation technology has become indispensable. As one of the core components of network communication equipment, the concentrator contains a large number of electronic components that generate a significant amount of heat during operation. If this heat is not dissipated effectively and promptly, it will not only lead to a decline in equipment performance but also shorten its lifespan and even cause equipment failure. The main function of the concentrator's heat dissipation structure is to effectively dissipate the internal heat while ensuring the normal operation of the equipment. Currently, common concentrator heat dissipation structures mainly include natural cooling, forced air cooling, and liquid cooling. Natural cooling relies on the temperature difference between the inside and outside of the device to drive airflow and achieve heat dissipation; forced air cooling uses an internal fan to force airflow, improving heat dissipation efficiency; and liquid cooling uses liquid as a cooling medium, carrying away heat through a circulation system.

[0003] Despite the various cooling solutions available on the market, several shortcomings remain in practical applications. Specifically: traditional cooling structures often only provide overall cooling, failing to effectively dissipate heat in localized hotspots, particularly in high-power-density devices where localized overheating is especially pronounced. While forced air cooling offers high efficiency, the noise generated by the fans is significant, impacting user experience, especially in quiet environments. Both forced air and liquid cooling systems require additional energy to operate, increasing overall energy consumption and contradicting energy conservation and emission reduction goals. Failures in existing cooling systems often necessitate downtime for repair or replacement, disrupting normal operation and increasing maintenance costs. Traditional cooling systems are prone to wear and aging during long-term operation, especially moving parts like fans, which are susceptible to failure due to prolonged use, thus affecting cooling performance. Utility Model Content

[0004] In view of this, the present invention provides a modular and replaceable concentrator heat dissipation structure, which solves the drawback of traditional heat dissipation structures that can only dissipate heat for the whole and have poor heat dissipation effect for local hot spots, thereby improving heat dissipation efficiency.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a modular and replaceable concentrator heat dissipation structure, which includes a main body. The main body is provided with at least one heat pipe and at least one microchannel. The two ends of the heat pipe are respectively located near the heat source and away from the heat source of the main body. The microchannel is arranged near the hot end of the heat pipe. The heat pipe includes an evaporation section, a condensation section and an insulation section. The evaporation section, condensation section and insulation section are connected by a connector. The evaporation section is close to the heat source, the condensation section is located away from the heat source, and the insulation section is located between the evaporation section and the condensation section.

[0007] The evaporation section is typically located near the heat source, specifically near the heating element inside the concentrator; the condensation section is situated away from the heat source to facilitate heat release; and the adiabatic section lies between the two, its function being to reduce heat diffusion along the non-working area of ​​the heat pipe, thereby improving the heat pipe's efficiency. The evaporation, condensation, and adiabatic sections of a heat pipe are a continuous, integrated structure, usually manufactured through precision machining to ensure seamless connections between sections. Furthermore, to ensure the functional independence of each part of the heat pipe, certain insulation measures may be implemented in the adiabatic section, such as using specific materials or coatings.

[0008] By combining heat pipes with microchannels, a composite heat dissipation structure is formed. This structure can quickly remove heat from localized hot spots (the role of microchannels) and evenly distribute heat (the role of heat pipes), thereby improving overall heat dissipation efficiency. The segmented design of the heat pipe (evaporation section, condensation section, and adiabatic section) helps to clarify the function of each section: the evaporation section is responsible for heat absorption, the condensation section is responsible for heat dissipation, and the adiabatic section reduces heat loss, thus improving the overall heat dissipation efficiency of the heat pipe.

[0009] Based on the above technical solution, the modular and replaceable concentrator heat dissipation structure of this utility model can be further improved as follows:

[0010] The microchannels are fixed to the surface of the evaporation section with an adhesive and directly absorb the heat transferred from the heat pipe through thermal conduction.

[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: Microchannels, arranged near the hot end of the heat pipe, can quickly absorb and remove heat from localized high-temperature areas, preventing localized overheating and improving the response speed and thermal management capability of the heat dissipation system. Microchannels, arranged on the surface of the heat pipe's evaporation section, directly absorb heat transferred by the heat pipe, reducing the heat transfer path and improving heat conduction efficiency.

[0012] Furthermore, the microchannel includes a series of parallel channels, each channel having an inlet and an outlet, each channel having a width of less than 1 mm, and the inlet and outlet of the microchannel being located on different sides of the main body.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the elongated microchannel increases the contact area with the coolant, improves the heat exchange efficiency, reduces the thermal resistance in the heat transfer process, and enhances the heat dissipation effect.

[0014] Furthermore, the arrangement density of the microchannels is greater than 100 channels / cm. 2 .

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are: the high-density microchannel arrangement increases the heat exchange area per unit volume, improves the heat exchange rate, and further enhances the heat dissipation capacity.

[0016] Furthermore, the outer side of the condensation section is provided with heat dissipation fins, which are connected to the outer side of the condensation section by welding, riveting or screwing.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the heat dissipation fins increase the surface area of ​​the heat pipe condensation section, accelerate the dissipation of heat, improve the heat dissipation efficiency of the condensation section, and further enhance the overall heat dissipation performance.

[0018] Furthermore, the heat dissipation fins are arranged in a serrated pattern, with each serration having an inclination angle between 30° and 60°.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the serrated arrangement of heat dissipation fins optimizes airflow guidance, improves airflow efficiency, accelerates heat transfer speed, and enhances heat dissipation effect.

[0020] Furthermore, a sealing ring is provided at the connection between the heat pipe and the microchannel, and the diameter of the heat pipe is greater than 5mm.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: a sealing ring is set at the connection between the heat pipe and the microchannel to prevent coolant leakage, ensuring the safety of the system and extending the service life of the equipment.

[0022] Furthermore, both ends of the heat pipe are fixed inside the main body by metal brackets, and the interior of the heat pipe is filled with a liquid working medium, such as water or alcohol solution.

[0023] Metal brackets are typically made of high-strength, corrosion-resistant materials, such as stainless steel or aluminum alloy, to ensure their robustness and durability. Metal brackets can be secured to the concentrator frame via welding, bolting, or clips. Welding is suitable for applications where disassembly is difficult, while bolting and clips facilitate disassembly and maintenance.

[0024] The proper arrangement of the heat pipes at both ends allows heat to be rapidly transferred from the heat source to a location farther away, preventing heat accumulation near the heat source, reducing the temperature in the heat source area, and extending the equipment's lifespan. The heat pipes are filled with a highly thermally conductive liquid working medium, which improves heat transfer efficiency, enabling heat to be transferred from the heat source to the heat dissipation area more quickly and enhancing the response speed of the cooling system.

[0025] Furthermore, the microchannel is made of copper alloy material.

[0026] Furthermore, the connector is obtained by metal welding or mechanical fastening.

[0027] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by connecting the heat pipe sections by metal welding or mechanical fixing, the stability of the heat pipe structure is ensured, and the risk of heat pipe failure due to vibration or thermal expansion and contraction is reduced.

[0028] Compared with existing technologies, the advantages of the modular and replaceable concentrator heat dissipation structure provided by this utility model are:

[0029] Improve heat dissipation efficiency:

[0030] This invention combines heat pipes and microchannels to form a composite heat dissipation structure. The heat pipe, as a highly efficient heat transfer element, can transfer heat from the heat source area to the heat dissipation area in a short time; while the microchannel can quickly remove heat from localized hot spots, thus significantly improving heat dissipation efficiency. Compared to traditional single heat dissipation methods, this invention can achieve a more uniform and efficient heat distribution without increasing additional energy consumption, effectively preventing localized overheating.

[0031] Reduce noise:

[0032] Because this invention employs a design combining heat pipes and microchannels, its noise level is significantly reduced compared to traditional forced air cooling systems. The heat pipes themselves achieve efficient heat transfer without any moving parts, while the microchannel design increases heat exchange area to improve heat dissipation efficiency, thereby reducing the need for noise sources such as fans. Even when fan assistance is required, the improved heat dissipation allows for a reduction in fan speed, further minimizing noise.

[0033] Energy saving and environmental protection:

[0034] This invention not only improves heat dissipation efficiency but also reduces the need for additional energy. As a highly efficient heat transfer element, the heat pipe's working principle does not rely on external energy; heat transfer is achieved solely through the phase change process of the internal working medium. Furthermore, the microchannel design increases surface area to enhance heat exchange efficiency, further reducing reliance on forced air cooling systems and thus achieving energy savings. This is of significant importance for data centers and high-performance computing environments that prioritize energy conservation and emission reduction.

[0035] Easy to maintain:

[0036] The modular design of this invention allows for independent replacement of each component. When a part fails, it can be replaced directly without affecting the normal operation of other components. This design not only simplifies the maintenance process and reduces maintenance costs, but also improves the availability and reliability of the equipment. Users can replace components without shutting down the system, reducing downtime and ensuring continuous system operation.

[0037] Enhanced reliability:

[0038] Traditional cooling systems are prone to wear and aging during long-term operation, especially moving parts such as fans, which are susceptible to failure due to prolonged use. This invention reduces reliance on moving parts and improves system reliability by combining heat pipes and microchannels. Both heat pipes and microchannels are static components, less susceptible to wear and aging, thus extending the lifespan of the entire cooling system. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0046] like Figure 1 , Figure 2 , Figure 3 The diagram shows a first embodiment of a modular, replaceable concentrator heat dissipation structure provided by this utility model. In this embodiment, it includes a main body 10, which is equipped with at least one heat pipe 20 and at least one microchannel 30. The two ends of the heat pipe 20 are respectively located near and away from the heat source of the main body 10. The microchannel 30 is arranged near the hot end of the heat pipe 20. The heat pipe 20 includes an evaporation section 21, a condensation section 22, and an insulation section 23. The evaporation section 21, condensation section 22, and insulation section 23 are connected by a connector 11. The evaporation section 21 is close to the heat source, the condensation section 22 is located away from the heat source, and the insulation section 23 is located between the evaporation section 21 and the condensation section 22. The modular, replaceable concentrator heat dissipation structure mainly includes the following core components: heat pipe, microchannel, metal support, heat dissipation fins, temperature sensor, etc. These components cooperate to form a highly efficient heat dissipation system.

[0047] Heat pipes: Heat pipes have a relatively large diameter, generally between 5mm and 20mm, with the specific size depending on the heat load and heat dissipation requirements. The length of the heat pipe depends on the layout of the concentrator and the location of the heat source.

[0048] Microchannels: Microchannels are small in size, typically ranging from a few hundred micrometers to a few millimeters in width, and correspondingly shallow in depth. They are designed to increase surface area and improve heat exchange efficiency.

[0049] In the above technical solution, the microchannel 30 is fixed to the surface of the evaporation section 21 by an adhesive and directly absorbs the heat transferred from the heat pipe 20 through heat conduction.

[0050] Furthermore, in the above technical solution, the microchannel 30 includes a series of parallel channels, each channel having an inlet and an outlet. The width of each channel is less than 1 mm, and the inlet and outlet of the microchannel 30 are located on different sides of the main body 10.

[0051] Furthermore, in the above technical solution, the arrangement density of the microchannels 30 is greater than 100 channels / cm. 2 .

[0052] Furthermore, in the above technical solution, heat dissipation fins are provided on the outer side of the condensation section 22, and the heat dissipation fins are connected to the outer side of the condensation section 22 by welding, riveting or screws.

[0053] Furthermore, in the above technical solution, the heat dissipation fins are arranged in a serrated pattern, with the tilt angle of each serration between 30° and 60°.

[0054] Furthermore, in the above technical solution, a sealing ring is provided at the connection between the heat pipe 20 and the microchannel 30, and the diameter of the heat pipe 20 is greater than 5mm.

[0055] Furthermore, in the above technical solution, the two ends of the heat pipe 20 are fixed inside the main body 10 by metal brackets, and the interior of the heat pipe 20 is filled with a liquid working medium, such as water or alcohol solution.

[0056] Metal supports can be designed in U-shape, L-shape, or other forms suitable for securing heat pipes. For example, a U-shaped support can better support both ends of the heat pipe, while an L-shaped support can provide stable support on one side.

[0057] U-shaped bracket: The U-shaped bracket can be designed with two arms extending outwards, and the middle part is fixed to the concentrator frame. The two ends of the heat pipe are placed in the grooves of the U-shaped bracket and secured with fasteners to ensure that the heat pipe does not move.

[0058] L-shaped bracket: One arm of the L-shaped bracket is fixed to the concentrator frame, while the other arm is vertically upward or downward to support one end of the heat pipe. Multiple L-shaped brackets can be used to achieve stable fixation of the heat pipe.

[0059] The heat pipe is fixed to the concentrator frame at both ends by metal supports, especially the evaporator and condenser sections, to ensure their stability and accurate positioning. Depending on the length and weight of the heat pipe, a pair of metal supports can be installed at both ends, or an additional support can be added in the middle for more stable support.

[0060] Furthermore, in the above technical solution, the microchannel 30 is made of copper alloy material.

[0061] Furthermore, in the above technical solution, the connector 11 is obtained by metal welding or mechanical fixing.

[0062] Mechanical fixing methods may include, but are not limited to, the following:

[0063] Screw fixing: Use screws to fix the various parts of the heat pipe to the concentrator housing.

[0064] Clip-on connection: The heat pipe is fixed in the predetermined position by clips, which makes it easy to install and remove.

[0065] Clamping: The heat pipe is secured using specially designed clamps, which is suitable for situations requiring frequent maintenance or replacement of the heat pipe.

[0066] Specifically, the principle of this utility model is as follows:

[0067] Heat pipe technology principle:

[0068] A heat pipe is a highly efficient heat transfer element whose working principle is based on the phase change process of its internal working medium. The heat pipe is filled with a certain amount of working medium, typically water, alcohol, or other liquids with high thermal conductivity. When one end of the heat pipe (evaporation section) comes into contact with a heat source, the working medium is heated and vaporized. The vapor moves along the capillary structure inside the heat pipe to the other end (condensation section). Upon reaching the condensation section, the vapor liquefies upon cooling, releasing heat, which is then transferred to the external environment through heat conduction and convection. The liquefied working medium then returns to the evaporation section via capillary force within the heat pipe, completing one cycle. This process is repeated continuously, achieving efficient heat transfer.

[0069] Microchannel technology principle:

[0070] Microchannel technology refers to the arrangement of numerous tiny channels within a limited space to increase heat exchange area and improve heat exchange efficiency. Microchannels are typically very small, with widths ranging from hundreds of micrometers to a few millimeters and corresponding depths. These tiny channels significantly increase the surface area per unit volume, thereby increasing the heat exchange rate. The coolant within the microchannels flows rapidly, quickly carrying away heat and preventing localized overheating. Furthermore, the design of microchannels can optimize flow field distribution, improving the overall performance of the cooling system.

[0071] The principle of combining heat pipes and microchannels:

[0072] This invention combines heat pipes and microchannels to form a composite heat dissipation structure. The heat pipes are responsible for evenly distributing heat from the heat source area to the entire heat dissipation system, while the microchannels focus on quickly removing heat from localized hot spots. Specifically:

[0073] The combination of heat pipes and microchannels: The evaporation section of the heat pipe is located near the heat source, while the condensation section is located away from the heat source. Heat is transferred from the heat source to the condensation section through the phase change process of the working medium inside the heat pipe. The microchannels are closely arranged on the surface of the evaporation section of the heat pipe, directly absorbing the heat transferred from the heat pipe and carrying it away through the flow of coolant.

[0074] Optimized structural design: The combination of heat pipes and microchannels not only improves heat dissipation efficiency but also optimizes the overall heat dissipation structure design. The segmented design of the heat pipes (evaporation section, condensation section, and adiabatic section) ensures effective heat transfer, while the high-density arrangement of the microchannels increases the heat exchange area and improves the heat exchange rate.

[0075] Enhanced thermal management capabilities: Through the synergistic operation of heat pipes and microchannels, this invention can effectively manage the heat distribution inside the equipment, prevent local overheating, and thus improve the stability and reliability of the equipment.
