Description

Technical Field

[0001] This invention relates to the technical field of waste heat removal and passive heat exchange devices, specifically to a modular installation and fixing structure and method for modularly splicing, positioning, bearing, and releasing thermal displacement of multiple separate heat pipe modules with finned tube bundle condensation sections in a waste heat removal water tank. Background Technology

[0002] Split heat pipes utilize the phase change of the working fluid to achieve heat transfer, making them suitable for waste heat removal, emergency cooling, and passive heat exchange scenarios. When installing split heat pipes in a waste heat removal tank, the evaporator section is typically submerged in the tank water or near the heat source area, while the condenser section is located in the upper part of the tank or in an external heat dissipation area. For structures using finned tube bundles as the condenser section, cooling air typically enters from below the finned tube bundle and exits from above to carry away the heat released during condensation.

[0003] In engineering applications, to obtain a larger heat exchange area, it is often necessary to assemble multiple separate heat pipes into modules and install these modules in an array along the length or width of the water tank. Traditional installation methods often involve installing individual heat pipes one by one, welding the overall frame, or rigidly clamping it, which suffers from low assembly efficiency, poor positioning accuracy, difficulty in splicing between modules, and inconvenient maintenance. If a solid plate-like top frame or a covered bracket is used to fix the condenser section, it can easily obstruct the air inlet or outlet surface of the finned tube bundle, increasing airflow resistance and reducing the condensation heat dissipation effect.

[0004] Furthermore, split heat pipes undergo thermal expansion and contraction due to temperature changes during operation. If the condenser section, connecting pipe, and evaporator section are all rigidly fixed, additional thermal stress is easily generated at the installation points of the condenser section, the riser pipe, the downcomer pipe, and the connection points of the evaporator section. If the fixing is insufficient, the evaporator section is prone to lateral swaying under the influence of water flow disturbance, filling and draining impact, or external vibration. Therefore, an installation and fixing structure and method are needed that can modularly support and splice the condenser section of the heat pipe without obstructing its bottom air intake and top air exhaust heat dissipation path, and can release thermal displacement and limit the swaying of the evaporator section. Summary of the Invention

[0005] The purpose of this invention is to provide a modular, split heat pipe splicing installation and fixing structure and installation method to solve the problems in the prior art, such as difficulty in installing and positioning multi-heat pipe modules, insufficient reliability of splicing between modules, obstructed ventilation in the condensation section, poor heat displacement release capacity, and insufficient operational stability of the evaporation section.

[0006] To achieve the above objectives, this invention provides a modular, modular, split heat pipe assembly and fixing structure, including a water tank, multiple split heat pipe modules, a supporting beam, an evaporation section guide, and inter-module connection interfaces. Each split heat pipe module includes an open module support frame and multiple split heat pipes mounted on the open module support frame. Each split heat pipe includes a condensing section, a riser pipe, a downcomer pipe, and an evaporation section. The condensing section is located within the open module support frame, and the evaporation section extends into the water tank via the riser pipe and the downcomer pipe.

[0007] The open-type modular support frame includes an outer perimeter frame, partition beams, and mounting ears. The outer perimeter frame forms the overall load-bearing outline, the partition beams divide the interior of the outer perimeter frame into multiple ventilation and installation spaces, and the mounting ears are located on opposite sides of the open-type modular support frame for connection to the load-bearing beams at the top of the water tank. When multiple modules are arranged in a row, two load-bearing beams extend continuously along opposite sides of the row of modules, and each module rests on the load-bearing beams on its own two sides via its mounting ears and can be detachably fixed. Thus, the middle modules do not rely on adjacent modules for suspension and load-bearing, but rather, like the end modules, directly bear the vertical load through the load-bearing beams.

[0008] The open-type modular support frame avoids the lower air inlet and upper air outlet of the condenser section, allowing air to enter from below and exit from above. The condenser section is fixed to the open-type modular support frame by a lower support, side positioning blocks, upper pressure plate, bolts, and buffer pads. All of these fasteners are arranged on the outer periphery or end of the finned heat exchange area, and do not cover the lower air inlet, upper air outlet, or main heat exchange surface of the finned tube bundle.

[0009] The inter-module connection interface is located at the end or side of adjacent open module support frames and may include tenons, grooves, locking elements, and positioning holes. During installation, the tenon is inserted into the groove for initial positioning, the positioning hole is used for assembly alignment, and the locking element is used for locking after assembly. This structure allows adjacent modules to be reliably spliced ​​laterally, while the vertical load of the modules is borne by the support beam, and the inter-module connection interface does not serve as a primary vertical load-bearing component.

[0010] The evaporation section guide is installed inside the water tank and cooperates with the evaporation section to limit the lateral swing of the evaporation section. A guide gap is left between the evaporation section guide and the evaporation section to allow the evaporation section to release thermal expansion displacement vertically and prevent the evaporation section from being rigidly clamped.

[0011] The separate heat pipe module of this invention can be configured with different numbers of separate heat pipes according to the design heat load, such as two, three, four or more. By changing the number and installation position of the partition beams in the open module support frame, a ventilated installation space corresponding to the number of heat pipes can be formed; the fixing components of each condensing section and the guide components of the evaporating section can be increased or decreased synchronously according to the number of heat pipes, while the mounting ears on the outside of the module and the connection interfaces between modules remain uniform, thereby realizing standardized installation and replacement between modules with different heat exchange capacities.

[0012] Compared with existing technologies, the present invention has at least the following advantages: First, the open modular support frame only supports and positions the components on the outer periphery and in the non-finned support areas, without obstructing the vertical ventilation path of the condensing section; second, the open modular support frame enables the modular integration of multiple separate heat pipes, facilitating overall hoisting and rapid installation; third, each module is directly fixed to the support beam via its own mounting ears, and the interfaces between modules do not bear the main vertical load, ensuring a clear and reliable force path; fourth, the condensing section is fixed by a combination of fixed and floating points, ensuring positioning while releasing thermal displacement; fifth, the evaporating section guide components limit lateral sway and allow vertical thermal expansion and contraction, improving operational stability and reliability; sixth, the number of heat pipes inside the module is configurable, facilitating expansion or replacement according to heat exchange requirements.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention. Equivalent substitutions made by those skilled in the art in terms of the number of components, dimensions, connection methods, and materials without departing from the concept of the present invention should all fall within the scope of protection of the present invention.

[0021] like Figure 1 As shown, the modular split heat pipe of this embodiment includes a water tank 1, multiple split heat pipe modules, and a supporting beam 10. A heat source area 13 can be set inside the water tank 1, and an evaporation section 9 is located inside the water tank 1 and arranged close to or corresponding to the heat source area 13. Multiple split heat pipe modules are arranged sequentially along the top of the water tank 1, and an open module support frame 2 is supported on the supporting beam 10. Multiple split heat pipes can be integrated within each open module support frame 2, and each split heat pipe includes a condensing section 6, a riser pipe 7, a downcomer pipe 8, and an evaporation section 9. The condensing section 6 is located above the water tank, and air enters from below the condensing section 6 and exits from above.

[0022] like Figure 2 As shown, the open-type modular support frame 2 includes an outer perimeter frame 3, a partition beam 4, and mounting ears 5. The outer perimeter frame 3 forms a rectangular support frame, and the partition beam 4 is positioned between adjacent condenser sections 6, so that each condenser section 6 is located in a separately ventilated installation space. Both the outer perimeter frame 3 and the partition beam 4 avoid the main lower air intake area and upper air outlet area of ​​the condenser section 6.

[0023] like Figure 3 As shown, a single condenser section 6 is fixed within the open module support frame 2 via a lower support base 14, a side positioning block 15, an upper pressure plate 16, bolts 17, and a buffer pad 18. The middle part of the condenser section 6 is the finned heat exchange area, and its sides or ends are provided with non-finned load-bearing parts such as end plates, side frames, manifold seats, or mounting seats. The lower support base 14 is located below the non-finned load-bearing parts to support the weight of the condenser section; the side positioning block 15 is located to the side of the non-finned load-bearing parts to limit the lateral movement of the condenser section; the upper pressure plate 16 is located above the non-finned load-bearing parts and is connected to the open module support frame 2 via bolts 17; the buffer pad 18 is located between the upper pressure plate 16 and the non-finned load-bearing parts to reduce hard contact and local stress. All the above fixing components avoid the finned heat exchange area and do not directly cover the lower air inlet surface and upper air outlet surface of the condenser section 6 to ensure that air can pass through the finned tube bundle from bottom to top.

[0024] like Figure 4As shown, in a preferred embodiment, the condensation section 6 located in the middle is set as a fixed point, and the condensation sections 6 located on both sides are set as floating points. The fixed point uses a round hole and a bolt 17 to position the condensation section 6 relative to the open module support frame 2; the floating point uses an elongated hole 19 and a bolt 17 to allow the corresponding condensation section 6 to undergo a slight displacement along the direction of the elongated hole 19 when it expands due to heat or contracts due to cooling.

[0025] like Figure 5 As shown, the evaporation section guide 11 is installed inside the water tank 1 and surrounds or partially surrounds the outside of the evaporation section 9. A guide gap is maintained between the evaporation section guide 11 and the evaporation section 9. The guide gap is used to allow the evaporation section 9 to undergo thermal expansion and contraction displacement in the vertical direction. The evaporation section guide 11 limits the evaporation section 9 in the horizontal direction to reduce lateral swaying caused by water flow disturbance, filling and draining impact or external vibration.

[0026] like Figure 6 As shown, multiple open modular support frames 2 can be arranged in a row along the same direction, with two support beams 10 located on opposite sides of the row of modules and extending continuously along the arrangement direction. Each open modular support frame 2 is supported on the support beams 10 on both sides by mounting ears 5 on its own sides, and is detachably connected to the support beams 10 by bolts 17 or pressure plates. Inter-module connection interfaces 12 are provided between adjacent open modular support frames 2. The inter-module connection interfaces 12 are used for lateral positioning, splicing, and preventing relative misalignment of adjacent modules; the vertical load of each module is transferred to the support beams 10 through its own mounting ears 5, and the inter-module connection interfaces 12 do not serve as the main vertical load-bearing components.

[0027] During installation, firstly, load-bearing beams 10 are installed on opposite sides of the top of the water tank 1 along the module arrangement direction; then, the open module load-bearing frame 2 is placed on the load-bearing beams 10, so that the mounting ears 5 of each module fall on the load-bearing beams 10 on both sides and are fixed; then, the condensing section 6 is placed in the corresponding ventilation installation space of the open module load-bearing frame 2 and the non-fin load-bearing parts are fixed; then, the riser pipe 7, the downcomer pipe 8 and the evaporator section 9 connected to the condensing section 6 are placed into the water tank 1 as a whole; finally, the evaporator section guide 11 is installed, and the adjacent open module load-bearing frames 2 are laterally positioned and locked through the inter-module connection interface 12.

[0028] The number of heat pipes within a separate heat pipe module can be configured according to heat exchange requirements. For two-, three-, four-, or more heat pipe modules, the external mounting ears 5 of the open module support frame 2 and the inter-module connection interface 12 can remain uniform, while the internal ventilation installation space, partition beam 4, condenser section fixing components, and evaporator section guide components 11 can be increased or decreased accordingly based on the number of heat pipes. Therefore, modules with different heat exchange capacities can be installed, replaced, and expanded within the same water tank structure using a unified external mounting interface.
