Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for communication equipment, and in particular to a heat conduction structure based on heat pipe embedding. Background Technology

[0002] The heat pipe embedded heat conduction structure is designed based on the heat transfer performance of heat pipes. It is an easy-to-assemble, stable and reliable heat conduction and heat dissipation structure. Since the heat sink of outdoor equipment needs to be treated with high-temperature powder coating to protect the chassis from oxidation and corrosion, the heat pipes embedded in the heat sink cannot withstand the high temperature of the powder coating environment, which makes it impossible for the heat sink to undergo high-temperature powder coating surface treatment, thus failing to meet the equipment process requirements.

[0003] Because heat pipes are used in high-temperature environments for a long time, they are prone to damage or failure. Furthermore, the installation of heat pipes requires special equipment in the factory, and the surface of the heat pipes needs to be smoothed after installation. During maintenance, they cannot be directly removed from the radiator, and the entire radiator needs to be replaced, resulting in a large workload and high cost for maintenance. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a heat pipe embedded heat conduction structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a heat pipe embedded heat conduction structure, including: a heat pipe assembly 1, a substrate 2, a heat sink 3, an aviation socket 4, and a fan 5.

[0006] The heat pipe assembly 1 is composed of flattened heat pipes. The substrate 2 has a fixing groove adapted to the heat pipe assembly 1, and the heat pipe assembly 1 is embedded in the fixing groove. The inner surface of the heat sink 3 is provided with a cavity, and the substrate 2 is adapted to be installed in the cavity and fixedly connected to the heat sink 3. The heat sink 3 is provided with a plurality of heat dissipation fins 9, and the fan 5 is installed on the outside of the heat dissipation fins 9 for forced air cooling. The aviation socket 4 is fixedly installed on the side of the heat sink 3, and the power connector of the fan 5 is plugged into the aviation socket 4.

[0007] In one embodiment, the thickness of a single heat pipe in the heat pipe assembly 1 is the same as the thickness of the substrate 2, and the heat pipe assembly 1 is uniformly distributed within the fixing groove of the substrate 2.

[0008] In one embodiment, it also includes: a cross-head countersunk bolt 6;

[0009] The inner surface cavity of the radiator 3 is provided with several fixing holes on its side wall, and the cross-head countersunk bolts 6 pass through the fixing holes and are movably connected to the substrate 2.

[0010] In one embodiment, the heat dissipation fins 9 are arranged linearly along the length of the heat sink 3, with gaps between adjacent heat dissipation fins 9, and the air outlet direction of the fan 5 is consistent with the direction of these gaps.

[0011] In one embodiment, it also includes: a fan mounting cover 7 and a cross-head bolt 8;

[0012] The fan 5 is fixedly installed inside the fan mounting cover 7. The fan mounting cover 7 is detachably connected to the top of the heat sink 3 by a cross-head bolt 8, and the position of the fan mounting cover 7 corresponds to the position of the heat sink fins 9.

[0013] As can be seen from the above, this utility model provides a heat pipe-embedded heat conduction structure that innovatively embeds the heat pipe assembly into the substrate rather than directly fixing it to the heat sink. This allows the heat sink to undergo independent high-temperature powder coating treatment, avoiding the problem of heat pipe damage due to high temperatures and improving the corrosion resistance and weather resistance of the heat sink, perfectly meeting the process requirements of outdoor equipment. The heat pipe assembly and the substrate have the same thickness and are evenly distributed, significantly increasing the heat dissipation area. Combined with linearly arranged heat dissipation fins and forced air cooling by the fan, a highly efficient heat transfer path is formed, significantly improving heat dissipation efficiency. The components of this utility model adopt a movable connection design. The substrate and the heat sink are detachably connected by Phillips head bolts, facilitating the overall disassembly and replacement of the heat pipe assembly. The fan is installed through a fixing cover and Phillips head bolts, and the power connector is plugged into an aviation socket, greatly simplifying the fan maintenance process, effectively reducing maintenance costs and workload, and balancing heat dissipation performance, process compatibility, and maintainability. It has great practical value in the field of heat dissipation for communication equipment and high-power equipment. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0021] like Figure 1 and Figure 2 As shown, a heat pipe-embedded heat conduction structure is provided, including: heat pipe assembly 1, substrate 2, heat sink 3, aviation socket 4, fan 5, Phillips head countersunk screw 6, fan mounting cover 7, Phillips pan head screw 8, heat dissipation fins 9, heat input surface 10, and heat output surface 11.

[0022] The heat pipe assembly 1 consists of multiple flattened heat pipes. A fixing groove adapted to the heat pipe assembly 1 is formed on one side surface of the substrate 2 (the number and arrangement of the fixing grooves are the same as those of the heat pipe assembly 1). The heat pipe assembly 1 is embedded in the fixing groove, and the thickness of each heat pipe is the same as the thickness of the substrate 2. After embedding, the surface of the heat pipe assembly 1 is flush with the surface of the substrate 2. The heat pipe assembly 1 is evenly distributed on the substrate 2 to increase the heat dissipation area of ​​the heat source.

[0023] The heat sink 3 has a hollow structure, and its inner surface is provided with a cavity adapted to the substrate 2 (the size of the cavity is clearance-fitted with the size of the substrate 2); the outer surface of the heat sink 3 is treated with high temperature powder coating, and the side wall of the inner surface cavity is provided with several through fixing holes; the cross countersunk bolt 6 passes through the fixing hole and engages with the threaded hole on the edge of the substrate 2 to detachably fix the substrate 2 in the cavity of the heat sink 3, and the substrate 2 is tightly attached to the inner surface of the heat sink 3.

[0024] The top of the radiator 3 is integrally formed with several heat dissipation fins 9, which are arranged linearly along the length of the radiator 3. The gaps between adjacent heat dissipation fins 9 are left to form air circulation channels.

[0025] The fan mounting cover 7 is a frame structure. The fan 5 is fixedly installed inside the fan mounting cover 7 by a cross-head bolt 8. The edge of the fan mounting cover 7 has mounting holes. After the cross-head bolt 8 passes through the mounting holes, it engages with the threaded holes on the top of the heat sink 3, so that the fan mounting cover 7 and the fan 5 are detachably installed on the top of the heat sink fins 9, and the air outlet of the fan 5 is directly opposite the gap between the heat sink fins 9. The aviation socket 4 is fixedly installed on the side of the heat sink 3 by screws. The power connector of the fan 5 is plugged into the aviation socket 4 to provide power to the fan 5.

[0026] In one embodiment, the specific assembly process of this utility model is as follows:

[0027] First, pretreatment is carried out by high-temperature powder coating of radiator 3, and then it is ready for use.

[0028] The flattened heat pipe is embedded into the fixing groove of the substrate 2 and fixed by welding to ensure that the surface of the heat pipe is flush with the surface of the substrate 2.

[0029] Place the substrate 2 into the cavity on the inner surface of the heat sink 4 so that the substrate 2 fits against the inner surface of the heat sink 3. Use four cross countersunk bolts 8 to thread them through the fixing holes of the heat sink 3 and connect them to the substrate 2 to complete the fixing.

[0030] Fix the fan 5 inside the fan mounting cover 9, and install the fan mounting cover 9 on the top of the heat sink 3 using two cross-head bolts 10, so that the fan 5 is directly facing the gap of the heat sink fins 11; insert the power connector of the fan 5 into the aviation socket 4 to complete the circuit connection.

[0031] In operation, the external heat source is fixed on the heat input surface 10 of the substrate 2. The heat generated by the heat source is transferred to the heat pipe assembly 1 through the heat input surface of the substrate 2. According to the principle of heat pipe, the heat is quickly transferred to the heat output surface 11 through the capillary structure inside the heat pipe assembly 1, and then conducted from the heat output surface 11 to the heat dissipation fins 9. Finally, the fan 5 transfers the heat on the heat dissipation fins 9 out through forced air cooling. This structure can not only perform efficient heat dissipation, but also has the advantages of maintainability and reduced production costs.

[0032] When maintenance is required, if heat pipe assembly 1 is damaged, the Phillips head countersunk screw 6 can be unscrewed to remove the substrate 2 and heat pipe assembly 1 as a whole for replacement; if fan 5 is faulty, the power connector can be unplugged, the Phillips head pan screw 8 can be unscrewed to remove the fan mounting cover 7 and fan 5 for maintenance or replacement, which is convenient.

[0033] This utility model provides a heat conduction structure based on heat pipe embedding. By embedding the heat pipe assembly 1 into the substrate 2 instead of directly embedding it into the heat sink 3, the heat sink 3 can be independently treated with high-temperature powder coating, avoiding damage to the heat pipes due to high temperature, improving the corrosion resistance and weather resistance of the heat sink 3, and meeting the process requirements of outdoor equipment.

[0034] The heat pipe assembly 1 and the substrate 2 have the same thickness and are evenly distributed, which increases the heat dissipation area of ​​the heat source; the heat dissipation fins 9 are linearly arranged and combined with the fan 5 for forced air cooling to form an efficient heat transfer path, which significantly improves the heat transfer efficiency.

[0035] Each component adopts a movable connection design. The base plate 2 and the heat sink 3 are movably connected by a cross countersunk bolt 6. The heat pipe assembly 1 can be disassembled as a whole with the base plate 2, making it easy to replace the heat pipes individually. The fan 5 is detachably connected by a fan mounting cover 7 and a cross pan head bolt 8. The power connector is plugged into and unplugged with the aviation socket 4, which greatly simplifies the maintenance process of the fan 5, reduces maintenance costs, and takes into account heat dissipation performance, process compatibility and maintainability. It has great practical value in the field of heat dissipation of communication equipment and high-power equipment.
