Description

Technical Field

[0001] This invention belongs to the technical field of heat exchange devices, and specifically relates to a shell-type heat exchange enhancement component for the condensing section of a high-temperature heat pipe facing the Stirling hot end. Background Technology

[0002] High-temperature heat pipes are commonly used for heat transfer at the hot end of Stirling generators, and current methods often employ a direct plug-in coupling of the heat pipe's condenser section. This type of structure has limited heat exchange area, high interfacial contact thermal resistance, and poor phase change temperature homogenization and heat transfer enhancement effects, thus limiting thermoelectric conversion efficiency. Simultaneously, the hot-end heater is directly exposed to the biomass flue gas environment, making it prone to ash accumulation and high-temperature corrosion, shortening the equipment's lifespan. Conventional structures cannot achieve physical isolation between the heat source and the hot end, and are also difficult to adapt to the stable operating conditions of alkali metal high-temperature heat pipes at 450–1000℃. Therefore, a compact, high-efficiency shell-type heat exchange enhancement component is urgently needed.

[0003] A search revealed that Chinese Patent Publication No. CN112985132B, authorized on October 25, 2022, discloses a gravity heat pipe device for Stirling power generation and forced convection cooling. The device includes a gravity heat pipe, a piston drive structure, a power generation section, and a fan. The gravity heat pipe comprises an inner gas channel wall and an outer wall. The inner gas channel wall is located inside the outer wall, and a working fluid flow channel is provided at the lower end of the inner gas channel wall. A gas working fluid channel is located between the inner gas channel wall and the outer wall, and the working fluid flow channel is connected to the gas working fluid channel. A cylinder heating chamber is installed at the upper part of the gas working fluid channel, with a gap for gas passage. A piston drive structure is installed at the upper part of the cylinder heating chamber, and the piston drive structure is connected to the power generation section, which drives the fan. This application converts the heat from the gravity heat pipe in the gangue pile into mechanical energy. Its advantage is that the cylinder heating chamber can penetrate deep into the center of the heat pipe, providing a larger contact area with the vaporized working fluid and making greater use of the heat generated by the accumulated temperature deep within the gangue pile.

[0004] However, the equipment still has the following drawbacks: although it can make greater use of the heat generated by the accumulated temperature deep in the gangue mountain, it cannot achieve efficient heat exchange in the high-temperature heat pipe condensation section to ensure stable heat transfer to the Stirling hot end, resulting in an unsatisfactory heat exchange effect. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a shell-type heat exchange enhancement component for the condensing section of a high-temperature heat pipe facing the Stirling hot end, comprising a guide rail assembly; heat exchange shells are slidably connected to both the upper and lower sides of the inner wall of the guide rail assembly, and the two sets of heat exchange shells are symmetrically arranged with the central axis of the guide rail assembly as the center; heat channel assemblies are fixedly connected to the inner walls of both sets of heat exchange shells, and gas delivery assemblies are provided at both ends of the heat channel assembly; an arched cavity is provided on the side of the heat channel assembly away from the gas delivery assembly, and a high-temperature heat pipe condensing section is fitted to the inner wall of the arched cavity; the continuous operation of the gas delivery assembly forms a channel within the arched cavity for transferring heat from the high-temperature heat pipe condensing section; and a linkage assembly for protecting the high-temperature heat pipe condensing section is rotatably connected to the outer wall of the heat channel assembly.

[0006] Furthermore, the guide rail assembly includes an outer frame; the top of the outer frame is provided with an upper guide groove for guiding a set of heat exchange shells, the bottom of the outer frame is provided with a lower guide groove for guiding another set of heat exchange shells, and the outer wall of the outer frame and near the corners are provided with adjustment grooves.

[0007] Furthermore, the heat channel assembly includes a boss; one end of the boss is provided with an arc-shaped structure, and the end of the boss away from the arc-shaped structure is fixedly connected to the bottom of the inner wall of the heat exchange shell, one end of the heat exchange shell is an open structure, and one side of the arc-shaped structure of the boss extends to the opening of the heat exchange shell.

[0008] Furthermore, a guide groove is provided on the outer wall of the boss and at one end near the arc-shaped structure. Two sets of extension grooves are also provided on the outer wall of the boss, and the two sets of extension grooves are horizontally arranged at the bottom end of the guide groove. Both sets of extension grooves are connected to the guide groove.

[0009] Furthermore, a gear is rotatably connected to one side of the outer wall of the boss, and both sets of gears are located at the end of the extension groove. A handwheel is fixedly connected to the center of the central axis of both sets of gears, and the handwheel extends to the outer wall of the heat exchange shell. Several sets of flow guiding channels are opened on the inner wall of the boss.

[0010] Furthermore, the gas delivery assembly includes two sets of arched bends; the two sets of arched bends are distributed within each heat exchange shell, and the two sets of arched bends are sleeved on both ends of the boss. One end of each set of arched bends is connected to an air pump, and the air pump switches between different operating states to deliver gas or adsorb gas to the arched bends. The bottom of each set of arched bends is embedded with several sets of delivery branch pipes, and the other end of each set of delivery branch pipes passes through the boss and extends into the guide channel, which is used to form different heat exchange directions within the several sets of guide channels.

[0011] Furthermore, the linkage component includes a sealing isolation cover; the sealing isolation cover is fitted and connected to the outer wall of the boss, and both ends of the sealing isolation cover pass through the extension groove and extend into the arched cavity.

[0012] Furthermore, both ends of the sealing isolation cover are provided with external tooth protrusions, and the external tooth protrusions are meshed with gears. The inner wall of the sealing isolation cover is provided with a liquid-absorbing core liner plate, and the outer wall of the liquid-absorbing core liner plate is provided with several sets of seepage grooves.

[0013] Furthermore, an interlayer is provided between the inner liner of the liquid-absorbing core and the sealing isolation cover, and the plurality of groups of seepage grooves are all connected to the interlayer.

[0014] Furthermore, the top of the sealing isolation cover is provided with two sets of through holes for evaporation and heat dissipation. The inner wall of the sealing isolation cover and the side near the through holes are each equipped with a limiting protrusion, which is slidably fitted into the guide rail.

[0015] The beneficial effects of this invention are: 1. The heat exchange shell serves as the supporting base, where heat channel components are fixedly installed, providing a closed space for heat transfer. These heat channel components, in conjunction with gas delivery components at both ends, form a stable heat transfer channel within the arched cavity, efficiently removing heat dissipated from the high-temperature heat pipe condenser section. A linkage component is rotatably connected to the outer wall of the heat channel component, protecting the high-temperature heat pipe condenser section from external interference. All components work together to achieve highly efficient heat exchange in the high-temperature heat pipe condenser section, ensuring stable heat transfer to the Stirling hot end, while also enabling convenient assembly and long-term stable operation of the components.

[0016] 2. By sliding the upper and lower guide grooves on the outer frame, the two sets of heat exchange shells are slidable. The distance between the two sets of heat exchange shells is adjusted by sliding the threaded pin in the adjustment groove, so that they are precisely aligned with the condensing section of the high-temperature heat pipe. At the same time, the nuts on the threaded pins are tightened to achieve self-locking fixation of the two sets of heat exchange shells, ensuring the stability of the subsequent heat exchange process. At this time, the heat channel assembly and the gas delivery assembly are simultaneously in a standby state, ready for heat transfer.

[0017] 3. The heat is guided by the heat channel assembly to spread evenly inside the heat exchange shell. At the same time, the gas delivery assembly is activated to deliver high-temperature gas to the Stirling hot end. Through its interconnected microporous structure, the heat is transferred to the Stirling heater, completing the initial heat transfer.

[0018] 4. The inner liner of the liquid suction core further assists in heat conduction. The seepage grooves on its surface allow the liquid working fluid to be evenly distributed, avoiding local overheating and allowing heat to be transferred to the Stirling heater more efficiently. The gas delivery component works continuously, working in conjunction with the heat channel component to ensure stable heat transfer and ultimately achieve efficient heat exchange. At the same time, the heat exchange shell provides isolation and protection to prevent dust from entering and ensure long-term stable operation of the component.

After the two sets of horizontal tubes on the high-temperature heat pipe condensing section 7 are attached to the arched cavity 5, the nuts are tightened on each threaded pin 8 to self-lock and fix the adjusted two sets of heat exchange shells 2.

[0034] Furthermore, heat exchange joints 9 for providing heat to the Stirling heater are installed on the outer wall of the heat exchange shell 2 and near the corners, and the bottom end of the heat exchange joint 9 is connected to the output end of the air pump 43 through a pipe.

[0037] Specifically, component alignment and spacing adjustment: Operate the guide rail assembly 1, slide the two sets of heat exchange shells 2 through the upper guide groove 12 and lower guide groove 13 opened in the outer frame 11, and adjust the spacing of the two sets of heat exchange shells 2 by sliding the threaded pin 8 in the adjustment groove 14, so that it is precisely aligned with the high-temperature heat pipe condensing section 7; at the same time, tighten the nut on the threaded pin 8 to achieve self-locking fixation of the two sets of heat exchange shells 2, and ensure the stability of the subsequent heat exchange process; at this time, the heat channel assembly 3 and the gas delivery assembly 4 are simultaneously in the standby state, ready for heat transfer; Heat transfer and working fluid circulation: The high-temperature heat pipe condensing section 7 releases heat, which is guided by the heat channel assembly 3 to spread evenly into the heat exchange shell 2.
