Technical Field
[0001] The invention relates to the technical field of vibrating devices, in particular to an energy storage device with two-way flow guidance and temperature control. Background Art
[0002] With the development of the new energy industry, energy storage technology has become an important means of supporting distributed power generation, renewable energy grid integration, and energy system peak and frequency regulation. The increasing application of energy storage devices in photovoltaics, grid regulation, and industrial waste energy utilization places higher demands on their thermal management efficiency, response speed, and system stability. Especially when operating at high power density, the energy storage medium generates a large amount of heat. If the temperature cannot be regulated in a timely manner, it will not only affect the energy storage efficiency, but also cause thermal runaway and even safety accidents. Therefore, the development of an energy storage device that can precisely control temperature, has high responsiveness, and directional adaptability has become a key issue that the industry urgently needs to solve.
[0003] Existing methods typically regulate the temperature of the energy storage medium through single-channel superheat pipes, heat exchangers, or electrically controlled valves. While these systems can achieve some functionality, they often rely on complex electronic control systems and multiple actuators for drive regulation. This results in slow response and structural redundancy, leading to high system stability and long-term maintenance costs.
[0004] In the existing technology, first, the heat-conducting structure is usually rigidly fixed, with low contact efficiency, and it is difficult to cope with the influence of vibration and flow impact. Secondly, the single channel response is insufficient. Finally, the flow channel adjustment mechanism lacks the ability to control the flow rate and direction, and cannot automatically adjust the turbulence state according to the flow state. The overall adjustment mechanism lags and the control accuracy is limited. Therefore, those skilled in the art provide an energy storage device with bidirectional flow guidance temperature control to solve the problems raised in the above background. Summary of the Invention
[0005] The object of the present invention is to provide an energy storage device with two-way flow guidance and temperature control to solve the problems raised in the prior art.
[0006] To achieve the above object, the present invention provides the following technical solutions: The energy storage device includes an energy storage shell, a flow diversion deflection mechanism, a self-heat conduction connection mechanism and a disturbance switching mechanism. The energy storage shell is a hollow cylindrical structure. Both ends of the energy storage shell are provided with flow diversion channels, a heat conduction channel is provided in the energy storage shell, an energy storage medium cavity is provided in the energy storage shell, an upper flow diversion port is provided at the upper end of the energy storage shell, and a lower flow diversion port is provided at the lower end of the energy storage shell. The flow diversion deflection mechanism and the energy storage shell are tightly connected, the flow diversion deflection mechanism is arranged at the upper flow diversion port, the self-heat conduction connection mechanism is arranged on the side wall of the flow diversion channel, and the disturbance switching mechanism is arranged at the lower flow diversion port.
[0007] By adopting the above technical solution, the diversion deflection mechanism can automatically adjust the diversion direction according to the temperature change of the energy storage medium, thereby optimizing the heat conduction path. When the temperature of the energy storage medium rises, the diversion deflection mechanism guides the coolant to flow from top to bottom; conversely, when the temperature of the energy storage medium decreases, it guides the heating medium to flow from bottom to top, and through the heat conduction function of the self-heat-conducting connection mechanism on the side wall of the flow channel, the heat can be transferred to the entire energy storage medium cavity. The turbulence switching mechanism further adjusts the flow rate of the cold flow and the switching of the flow channel by changing the turbulence state at the lower diversion port, thereby effectively solving the temperature control problem and significantly improving the energy storage efficiency and safety, so that the energy storage device can realize the function of two-way diversion temperature control.
[0008] Furthermore, the guide deflection mechanism includes a guide plate, a floating push rod, an extrusion plate and a reset elastic member. The guide plate and the reset elastic member are fastened together, the reset elastic member and the energy storage shell are fastened together, the extrusion plate and the floating push rod are fastened together, the floating push rod and the guide plate are hinged together, the guide plate and the energy storage shell are hinged together, and the extrusion plate and the energy storage shell are slidingly connected.
[0009] By adopting the above technical solution, when the temperature of the energy storage medium changes, the extrusion plate is displaced due to the extrusion of the cooling medium, pushing the floating push rod, and the floating push rod drives the guide plate to rotate around the hinge point to achieve deflection of the diversion direction. The reset elastic member provides a restoring force to ensure that the guide plate can return to its initial position after the temperature change stops, thereby enabling the diversion deflection mechanism to respond to subtle changes in the temperature of the energy storage medium, automatically adjust the diversion direction, and optimize the heat conduction path.
[0010] Furthermore, the self-heat-conducting connection mechanism includes a heat-conducting contact plate, an elastic buffer arm and a deflector shell, the heat-conducting contact plate and the deflector shell are slidingly connected, the deflector shell and the energy storage shell are fastened, the elastic buffer arm and the energy storage shell are fastened, and the heat-conducting contact plate and the elastic buffer arm are fastened.
[0011] By adopting the above technical solution, the heat-conducting contact plate can slide on the guide cover shell and maintain close contact with the side wall of the guide channel through the elastic action of the elastic buffer arm, thereby ensuring effective heat transfer. When the heating medium in the guide channel flows, the heat is transferred to the energy storage medium cavity through the heat-conducting contact plate, thereby realizing the regulation of the energy storage medium temperature. The elastic buffer arm not only plays an elastic role, but also can absorb the vibration caused by the flow of the medium, thereby improving the stability and service life of the device.
[0012] Furthermore, the spoiler switching mechanism includes a spoiler, an eccentric counterweight, a rotating shaft, a limiting slide rail and a switching block, the spoiler and the rotating shaft are fastened together, the eccentric counterweight and the spoiler are slidingly connected, the rotating shaft and the switching block are fastened together, the limiting slide rail and the switching block are fastened together, the switching block and the energy storage shell are rotatably connected, and the eccentric counterweight and the limiting slide rail are slidingly connected.
[0013] By adopting the above technical solution, the eccentric counterweight block can slide in the limit slide rail, and according to the flow direction and flow rate of the medium, the centrifugal force generated by its own counterweight and the rotation of the spoiler around the rotating shaft can change the state of the turbulence, adjust the flow rate of the cold flow and the switching of the flow channel. When the coolant flows from top to bottom in the guide channel, the eccentric counterweight block slides to one side under the action of centrifugal force, driving the spoiler to rotate, so that the cold flow can flow out smoothly through the cold discharge port, and at the same time closes the hot charging port to prevent the heating medium from entering the energy storage medium cavity; conversely, when the heating medium flows from bottom to top, the hot charging port is opened so that the heating medium can squeeze the heat-conducting contact plate, and at the same time adjust the opening of the hot charging port and control the flow of the heating medium, thereby achieving precise control of the temperature of the energy storage medium.
[0014] Furthermore, a cold discharge port is provided on the switching block, a hot charging port is provided on the energy storage shell, the cold discharge port and the lower guide port are connected, the hot charging port and the lower guide port are connected, the hot charging port and the heat conduction channel are connected, the cold discharge port and the guide channel are connected, the cold discharge port is placed at an angle, and a spiral groove is provided on the energy storage shell.
[0015] By adopting this technical solution, the tilted cold outlet is used to activate the deflector's rotation, and the spiral groove further enhances the generation of swirl, thereby generating the centrifugal force of the eccentric counterweight, enhancing the turbulence switching mechanism's regulation of the cold flow velocity and flow channel switching. The spiral groove design not only optimizes the fluid dynamics within the deflector channel, but also improves the overall temperature control efficiency and response speed of the energy storage device.
[0016] Furthermore, the spoiler switching mechanism also includes a first electromagnetic block and a second electromagnetic block, the first electromagnetic block is tightly connected to the cold release port, the second electromagnetic block is tightly connected to the hot charging port, the first electromagnetic block and the eccentric counterweight block are magnetically attracted to each other, and the second electromagnetic block and the eccentric counterweight block are magnetically attracted to each other.
[0017] By adopting the above technical solution, the first and second electromagnetic blocks can fine-tune the position of the eccentric counterweight based on the signal from the temperature sensor. This not only controls the rotation angle of the spoiler, but also activates when the temperature sensor detects that the temperature of the energy storage medium is higher than the set value, attracting the eccentric counterweight toward the cold discharge port, increasing the spoiler's guiding effect on the cold flow and accelerating the cooling process. Conversely, when the temperature is lower than the set value, the second electromagnetic block activates, attracting the eccentric counterweight toward the hot charge port, adjusting the spoiler's position, increasing the flow of the heating medium, and raising the temperature of the energy storage medium. This electromagnetic-assisted adjustment mechanism not only improves temperature control accuracy but also enhances the energy storage device's adaptability to ambient temperature changes.
[0018] Furthermore, the flow disturbance switching mechanism and the flow guide deflection mechanism form a structural linkage relationship through the liquid flow direction and pressure difference in the flow guide channel; When the liquid flows from top to bottom: the guide plate deflects to open the upper guide port, the first electromagnetic block adjusts the position of the eccentric counterweight, the spoiler rotates under the action of the liquid flowing out of the cold discharge port, the eccentric counterweight adjusts its position to close the hot charge port, and the eccentric counterweight adjusts its position to control the opening size of the cold discharge port; When the liquid flows from bottom to top: the guide plate closes the upper guide port, the second electromagnetic block adjusts the position of the first electromagnetic block, the eccentric counterweight block adjusts its position to open the hot charging port, and the eccentric counterweight block adjusts its position to control the size of the hot charging port opening.
[0019] Furthermore, the energy storage device also includes a circulation pipe, a circulation pump, a heating box and a cooling box. The energy storage shell is connected to the circulation pipe, the circulation pipe is connected to the heating box, the circulation pipe is connected to the cooling box, the circulation pump is connected to the cooling box, and the circulation pump is connected to the heating box.
[0020] By adopting the above technical solution, the circulating pump provides circulation power for the media in the heating box and the cooling box, ensuring that the heating medium and the cooling medium can flow continuously in the energy storage device, thereby realizing continuous regulation and control of the temperature of the energy storage medium. The heating box is used to store the heating medium. When the temperature of the energy storage medium drops, the heating medium enters the energy storage device through the circulation pipe to provide heat to the energy storage medium; the cooling box is used to store the cooling medium. When the temperature of the energy storage medium rises, the cooling medium enters the energy storage device through the circulation pipe, absorbs the heat of the energy storage medium, and achieves a cooling effect. The design of this circulation system not only improves the heat exchange efficiency of the energy storage device, but also ensures the stability and controllability of the temperature of the energy storage medium, further improving the performance and safety of the energy storage device.
[0021] Furthermore, a temperature sensor is installed on the side wall of the energy storage medium cavity, and the circulation pump, the first electromagnetic block, and the second electromagnetic block are all electrically connected to the temperature sensor. A connecting block is provided on the switching block, and the connecting block is rotatably connected to the energy storage shell.
[0022] By adopting the above technical solution, the temperature sensor can monitor the temperature inside the energy storage medium cavity in real time and transmit the temperature signal to the circulation pump, the first electromagnetic block, and the second electromagnetic block. When the temperature sensor detects that the temperature of the energy storage medium is higher than the set value, the circulation pump starts and pumps the cooling medium in the cooling box into the energy storage device through the circulation pipe. At the same time, the first electromagnetic block is activated, attracting the eccentric counterweight block to move toward the cold outlet, increasing the guiding effect of the spoiler on the cold flow and accelerating the cooling process. At this time, the diversion deflection mechanism responds to the temperature change, and the deflector deflects to open the upper diversion port, guiding the cooling medium to flow from top to bottom. Through the adjustment of the spoiler switching mechanism, the cold flow flows smoothly out through the cold outlet, and at the same time closes the hot filling port to prevent the heating medium from entering the energy storage medium cavity, thereby achieving rapid cooling of the energy storage medium temperature.
[0023] Compared with the prior art, the present invention has the following beneficial effects: When the temperature rises, the deflector mechanism, driven by the pressure of the coolant, moves the extrusion plate downward, driving the floating push rod to rotate the deflector plate, thereby opening the upper deflector port to guide the cold air downward, forming a top-to-bottom cooling path. When the temperature drops, the return spring provides a return force that causes the deflector plate to close the upper deflector port, creating a bottom-to-top heating path. This mechanically linked response structure, constructed with a small number of parts, eliminates the need for external drivers and offers self-adjusting direction, significantly improving temperature control sensitivity and structural responsiveness.
[0024] The spoiler switching mechanism is tilted through the cold outlet and the switching block at the bottom of the energy storage housing and features a spiral groove. The eccentric counterweight automatically adjusts its position under the flow of the cold / hot medium, driven by centrifugal force. The spoiler rotates around the axis to switch the flow channel on and off. When the heating direction changes, the first or second electromagnetic block attracts the counterweight, generating a magnetic offset, thereby controlling the spoiler's rotation angle and guiding the cold / hot medium more precisely. This mechanical-magnetic control technology achieves controllable channel direction and flow rate, as well as adjustable opening. It offers the advantages of flexible adjustment, fast structural response, and high integration of control variable units.
[0025] The self-heating connection mechanism consists of a thermal contact plate, elastic buffer arms, and a flow deflector housing. The plate is connected to the flow deflector housing in a sliding manner, with the buffer arms applying continuous pressure to the sidewalls. This structure maintains close contact between the plate and the housing sidewalls during fluid flow. Even in the event of fluid shock or mechanical vibration, the buffer arms absorb energy to ensure stable contact, ensuring efficient heat transfer between the heat conduction channel and the energy storage cavity. Furthermore, it offers the advantages of adaptive fit, self-maintaining pressure, vibration suppression, and impact resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1 - Figure 6 As shown, the present invention provides a technical solution for an energy storage device with two-way flow guidance and temperature control: The energy storage device includes an energy storage shell 1, a flow diversion deflection mechanism 2, a self-heat conduction connection mechanism 3 and a disturbance switching mechanism 4.

[0030] By adopting the above technical solution, the flow guide and deflection mechanism 2 can automatically adjust the flow direction according to the temperature change of the energy storage medium, thereby optimizing the heat conduction path. When the temperature of the energy storage medium rises, the flow guide and deflection mechanism 2 guides the coolant to flow from top to bottom; conversely, when the temperature of the energy storage medium decreases, the heating medium is guided to flow from bottom to top, and through the heat conduction function of the self-heat-conducting connection mechanism 3 on the side wall of the flow channel, the heat can be transferred to the entire energy storage medium cavity 13. The turbulence switching mechanism 4 further adjusts the flow rate of the cold flow and the switching of the flow channel by changing the turbulence state at the lower guide port 15, thereby effectively solving the temperature control problem and significantly improving the energy storage efficiency and safety, so that the energy storage device realizes the function of two-way flow guide temperature control.
[0031] Furthermore, the guide deflection mechanism 2 includes a guide plate 21, a floating push rod 22, an extrusion plate 23 and a reset elastic member 24. The guide plate 21 and the reset elastic member 24 are fastened together, the reset elastic member 24 and the energy storage shell 1 are fastened together, the extrusion plate 23 and the floating push rod 22 are fastened together, the floating push rod 22 and the guide plate 21 are hinged together, the guide plate 21 and the energy storage shell 1 are hinged together, and the extrusion plate 23 and the energy storage shell 1 are slidingly connected.
[0032] By adopting the above technical solution, when the temperature of the energy storage medium changes, the extrusion plate 23 is displaced due to the extrusion of the cooling medium, pushing the floating push rod 22. The floating push rod 22 drives the guide plate 21 to rotate around the hinge point to achieve deflection of the diversion direction. The reset elastic member 24 provides a restoring force to ensure that the guide plate 21 can return to its initial position after the temperature change stops, thereby enabling the diversion deflection mechanism 2 to respond to subtle changes in the temperature of the energy storage medium, automatically adjust the diversion direction, and optimize the heat conduction path.
[0033] Furthermore, the self-heat-conducting connection mechanism 3 includes a heat-conducting contact plate 31, an elastic buffer arm 32 and a deflector shell 33. The heat-conducting contact plate 31 and the deflector shell 33 are slidingly connected, the deflector shell 33 and the energy storage shell 1 are fastened together, the elastic buffer arm 32 and the energy storage shell 1 are fastened together, and the heat-conducting contact plate 31 and the elastic buffer arm 32 are fastened together.
[0034] By adopting the above technical solution, the heat-conducting contact plate 31 can slide in the guide cover 33 and maintain close contact with the side wall of the guide channel 11 through the elastic action of the elastic buffer arm 32, thereby ensuring effective heat transfer. When the heating medium in the guide channel 11 flows, the heat is transferred to the energy storage medium cavity 13 through the heat-conducting contact plate 31, thereby achieving the regulation of the energy storage medium temperature. The elastic buffer arm 32 not only plays an elastic role, but also can absorb the vibration caused by the flow of the medium, thereby improving the stability and service life of the device.
[0035] Furthermore, the spoiler switching mechanism 4 includes a spoiler 41, an eccentric counterweight 42, a rotating shaft 43, a limiting slide 44 and a switching block 45. The spoiler 41 is fastened to the rotating shaft 43, the eccentric counterweight 42 and the spoiler 41 are slidingly connected, the rotating shaft 43 and the switching block 45 are fastened, the limiting slide 44 and the switching block 45 are fastened, the switching block 45 is rotatably connected to the energy storage shell 1, and the eccentric counterweight 42 and the limiting slide 44 are slidingly connected.
[0036] By adopting the above technical solution, the eccentric counterweight 42 can slide in the limiting slide rail 44, and according to the flow direction and flow rate of the medium, the centrifugal force generated by its own counterweight and the rotation of the spoiler 41 around the rotating shaft 43 can change the state of the turbulence, adjust the flow rate of the cold flow and the switching of the flow channel. When the coolant flows from top to bottom in the guide channel 11, the eccentric counterweight 42 slides to one side under the action of centrifugal force, driving the spoiler 41 to rotate, so that the cold flow can flow out smoothly through the cold discharge port 451, and at the same time closes the hot filling port 16 to prevent the heating medium from entering the energy storage medium cavity 13; conversely, when the heating medium flows from bottom to top, the hot filling port 16 is opened, so that the heating medium can squeeze the heat-conducting contact plate 31, and at the same time adjust the opening of the hot filling port 16 and control the flow rate of the heating medium, thereby achieving precise control of the temperature of the energy storage medium.
[0037] Furthermore, a cold discharge port 451 is provided on the switching block 45, and a hot charging port 16 is provided on the energy storage shell 1.

The cold discharge port 451 is placed at an angle, and a spiral groove 17 is provided on the energy storage shell 1.
[0038] By adopting this technical solution, the tilted placement of cold outlet 451 activates the rotation of guide plate 21. The spiral groove 17 further enhances the generation of swirl, thereby generating centrifugal force on eccentric counterweight 42 and enhancing the regulation of cold flow velocity and flow channel switching by turbulence switching mechanism 4. The design of spiral groove 17 not only optimizes the fluid dynamics within guide channel 11 but also improves the overall temperature control efficiency and response speed of the energy storage device.
[0039] Furthermore, the spoiler switching mechanism 4 also includes a first electromagnetic block 46 and a second electromagnetic block 47. The first electromagnetic block 46 is fastened to the cold release port 451, and the second electromagnetic block 47 is fastened to the hot charging port 16. The first electromagnetic block 46 and the eccentric counterweight block 42 are magnetically attracted to each other for transmission, and the second electromagnetic block 47 and the eccentric counterweight block 42 are magnetically attracted to each other for transmission.
[0040] By adopting the above technical solution, the first electromagnetic block 46 and the second electromagnetic block 47 can fine-tune the position of the eccentric counterweight 42 according to the signal from the temperature sensor 9. On the one hand, this allows control of the rotation angle of the spoiler 41. On the other hand, when the temperature sensor 9 detects that the temperature of the energy storage medium is higher than the set value, the first electromagnetic block 46 is activated, attracting the eccentric counterweight 42 to move toward the cold discharge port 451, increasing the guiding effect of the spoiler 41 on the cold flow and accelerating the cooling process. Conversely, when the temperature is lower than the set value, the second electromagnetic block 47 is activated, attracting the eccentric counterweight 42 to move toward the hot charging port 16, adjusting the position of the spoiler 41, increasing the flow rate of the heating medium, and raising the temperature of the energy storage medium. This electromagnetic-assisted adjustment mechanism not only improves the temperature control accuracy, but also enhances the energy storage device's adaptability to changes in ambient temperature.
[0041] Furthermore, the flow disturbance switching mechanism 4 and the flow guide deflection mechanism 2 form a structural linkage relationship through the liquid flow direction and pressure difference in the flow guide channel 11; When the liquid flows from top to bottom: the guide plate 21 deflects to open the upper guide port 14, the first electromagnetic block 46 adjusts the position of the eccentric counterweight 42, the spoiler 41 rotates under the action of the liquid flowing out of the cold discharge port 451, and the eccentric counterweight 42 adjusts its position to close the hot charging port 16. The eccentric counterweight 42 adjusts its position to control the opening size of the cold discharge port 451; When the liquid flows from bottom to top: the guide plate 21 closes the upper guide port 14, the second electromagnetic block 47 adjusts the position of the first electromagnetic block 46, the eccentric counterweight block 42 adjusts its position to open the thermal charging port 16, and the eccentric counterweight block 42 adjusts its position to control the size of the opening of the thermal charging port 16.
[0042] Furthermore, the energy storage device also includes a circulation pipe 5, a circulation pump 6, a heating box 7 and a cooling box 8. The energy storage shell 1 is connected to the circulation pipe 5, the circulation pipe 5 is connected to the heating box 7, the circulation pipe 5 is connected to the cooling box 8, the circulation pump 6 is connected to the cooling box 8, and the circulation pump 6 is connected to the heating box 7.
[0043] By adopting the above technical solution, the circulating pump 6 provides circulation power for the media in the heating box 7 and the cooling box 8, ensuring that the heating medium and the cooling medium can continue to flow in the energy storage device, thereby realizing continuous regulation and control of the temperature of the energy storage medium. The heating box 7 is used to store the heating medium. When the temperature of the energy storage medium decreases, the heating medium enters the energy storage device through the circulation pipe 5 to provide heat for the energy storage medium; the cooling box 8 is used to store the cooling medium. When the temperature of the energy storage medium increases, the cooling medium enters the energy storage device through the circulation pipe 5, absorbs the heat of the energy storage medium, and achieves a cooling effect. The design of this circulation system not only improves the heat exchange efficiency of the energy storage device, but also ensures the stability and controllability of the temperature of the energy storage medium, further improving the performance and safety of the energy storage device.
[0044] Furthermore, a temperature sensor 9 is installed on the side wall of the energy storage medium cavity 13, and the circulation pump 6, the first electromagnetic block 46, and the second electromagnetic block 47 are all electrically connected to the temperature sensor 9. A connecting block 452 is provided on the switching block 45, and the connecting block 452 is rotatably connected to the energy storage shell 1.
[0045] By adopting the above technical solution, the temperature sensor 9 can monitor the temperature within the energy storage medium cavity 13 in real time and transmit the temperature signal to the circulation pump 6, the first electromagnetic block 46 and the second electromagnetic block 47. When the temperature sensor 9 detects that the temperature of the energy storage medium is higher than the set value, the circulation pump 6 starts, pumping the cooling medium in the cooling box 8 into the energy storage device through the circulation pipe 5. At the same time, the first electromagnetic block 46 is activated, attracting the eccentric counterweight 42 to move toward the cold outlet 451, increasing the guiding effect of the spoiler 41 on the cold flow and accelerating the cooling process. At this time, the diversion deflection mechanism 2 responds to the temperature change, and the deflector 21 deflects to open the upper guide port 14, guiding the cooling medium to flow from top to bottom. Through the regulation of the spoiler switching mechanism 4, the cold flow flows smoothly through the cold outlet 451, while closing the hot filling port 16 to prevent the heating medium from entering the energy storage medium cavity 13, thereby achieving rapid cooling of the energy storage medium temperature.
[0046] Working principle of the present invention: When the temperature of the diversion deflection mechanism 2 rises, it is pushed by the pressure of the cooling medium, and the extrusion plate 23 moves downward, driving the floating push rod 22 to rotate the diversion plate 21, thereby opening the upper diversion port 14 to guide the cold flow downward, forming a cooling path from top to bottom. When the temperature drops, the reset elastic member 24 provides a return force to make the diversion plate 21 close the upper diversion port 14, forming a heating channel from bottom to top. The mechanical linkage response structure is formed by a small number of parts, eliminating the need for external drive, and has a self-adjusting direction function, which significantly improves the temperature control sensitivity and structural responsiveness; the spoiler switching mechanism 4 is tilted at the bottom of the energy storage shell 1 through the cold outlet 451 and the switching block 45 and has a spiral groove 17. The eccentric counterweight block 42 is automatically adjusted to its position by the centrifugal force under the flow of cold / hot medium, and the spoiler 41 rotates around the rotating shaft 43 to switch the flow channel on and off. When the heating direction changes, the first or second electromagnetic block 47 attracts the counterweight to generate a magnetic offset, thereby controlling the rotation angle of the spoiler 41 and guiding the cold / hot medium more precisely. This technology realizes a mechanical-magnetic control composite flow channel control technology with controllable channel direction, flow rate, and adjustable opening. This technology offers the advantages of flexible adjustment, fast structural response, and high integration of control variable units. The self-heating connection mechanism 3 is composed of a heat-conducting contact plate 31, an elastic buffer arm 32, and a flow deflector shell 33. The heat-conducting plate is slidably connected to the flow deflector shell 33, and the buffer arm continuously applies pressure to the side wall. This structure maintains the heat-conducting plate in close contact with the shell side wall during medium flow. Even in the event of fluid impact or mechanical vibration, the buffer arm can absorb energy to ensure stable contact, thereby ensuring efficient heat transfer between the heat-conducting channel 12 and the energy storage chamber. This structure offers multiple advantages: more adaptive contact, self-maintaining pressure, vibration suppression, and impact resistance.
