Abstract
Description
Technical Field
[0001] This invention relates to the field of electromagnetically driven pulsating heat pipe heat dissipation technology, and in particular to an electromagnetically driven pulsating heat pipe heat dissipation system and control method. Background Technology
[0002] Research on motor vehicle exhaust emissions has attracted the attention of relevant experts.
[0003] When an ozone generator is working, it generates a lot of heat, causing the temperature of the ozone generator to rise continuously. If heat is not dissipated in time, the ozone generator will malfunction when the temperature reaches a certain level.
[0004] A heat pipe, also known as a "superheater pipe," is a heat transfer technology developed in the 1960s. A heat pipe is a heat transfer element that utilizes the vaporization and condensation phase change of its internal saturated working fluid to achieve heat exchange. This phase change heat transfer method has a very high heat transfer capacity; compared to metals with good thermal conductivity such as copper and aluminum, the heat transfer capacity per unit mass of a heat pipe is several orders of magnitude higher. Structurally, a heat pipe mainly consists of three parts: an evaporation section (heating section), a condensation section (cooling section), and an intermediate adiabatic section.
[0005] Compared to traditional heat pipes, pulsating heat pipes do not require a wick. They achieve efficient heat transfer by oscillating gas and liquid plugs back and forth between the evaporation and condensation sections. Although pulsating heat pipes have a simple structure, their internal gas-liquid two-phase flow involves multiple heat transfer mechanisms, including sensible heat transfer, latent heat transfer, and expansion work, resulting in a complex operating mechanism and numerous influencing factors.
[0006] In existing technologies, the heat exchange medium in a heat pipe may stagnate during flow, which prevents the heat exchange medium from circulating efficiently, affecting the heat exchange effect and quality. Therefore, improvements are needed. Summary of the Invention
[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electromagnetically driven pulsating heat pipe cooling system and its control method.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] An electromagnetically driven pulsating heat pipe cooling system includes a cooling mechanism, in which a pulsating heat pipe assembly is disposed. The lower end of the pulsating heat pipe assembly passes through the cooling mechanism and extends to the lower end of the cooling mechanism. A heating mechanism is provided at the lower end of the pulsating heat pipe assembly, and a monitoring and acquisition mechanism is connected to the middle of the pulsating heat pipe assembly.
[0010] The heat dissipation mechanism is equipped with an electronically controlled pulse assembly, which consists of a mounting frame assembly and multiple electronically controlled directional pulse devices. The multiple electronically controlled directional pulse devices are installed on the mounting frame assembly at equal intervals. The pulsed heat pipe assembly has multiple semi-circular arc-shaped pipe fittings at one end within the heat dissipation mechanism. The multiple electronically controlled directional pulse devices are respectively located at the upper ends of the multiple semi-circular arc-shaped pipe fittings. The pulsed heat pipe assembly contains a heat exchange medium with magnetic beads.
[0011] The pulse direction of the electrically controlled directional pulse device is consistent with the flow direction of the heat exchange medium with magnetic beads.
[0012] Compared with the prior art, this application can quickly heat the evaporation section of the pulsed heat pipe assembly through the heat absorber assembly. The heating operation can raise the temperature of the heat exchange medium with magnetic beads, and the heat dissipation mechanism can cool down the heat exchange medium with magnetic beads. The detection mechanism can monitor the cooling status of the heat exchange medium, and the electronically controlled pulse assembly can ensure the stable flow of the heat exchange medium with magnetic beads to achieve circulation of the heat exchange medium and avoid jamming.
[0013] Preferably, the heat dissipation mechanism includes a heat dissipation ventilation pipe, an axial flow heat dissipation fan assembly is installed in the air outlet end of the heat dissipation ventilation pipe, and the mounting bracket assembly is installed on the top inside the heat dissipation ventilation pipe.
[0014] Furthermore, the axial flow cooling fan assembly enables rapid gas flow, effectively removing heat from the surface of the condenser section and helping to significantly reduce the temperature within the condenser section.
[0015] Preferably, the heating mechanism is installed on the heat-absorbing plate assembly at the lower end of the pulsating heat pipe assembly, and a heat source assembly is connected to one side of the heat-absorbing plate assembly.
[0016] Furthermore, the heat source component enables the heat absorption plate component to operate, thereby raising the temperature of the heat exchange medium within the evaporation section.
[0017] Preferably, the monitoring and acquisition mechanism includes multiple temperature detection components (7) installed on the pulsating heat pipe assembly (4), and a PLC control component (6) is connected to one side of the multiple temperature detection components (7). The PLC control component (6) is connected to multiple electrically controlled directional pulse devices (32).
[0018] Furthermore, it facilitates accurate detection of the temperature within each insulation section of the pulsating heat pipe assembly, and can also calculate the temperature difference, so as to transmit the data to the PLC control assembly and control the operation of the corresponding electronically controlled directional pulse device according to the pre-input data.
[0019] Preferably, the pulsating heat pipe assembly includes a coil, a siphon tube assembly is installed inside the coil, and the heat exchange medium with magnetic beads is located inside the siphon tube assembly;
[0020] The pulsating heat pipe assembly has a condensation section, an insulation section, and an evaporation section from top to bottom. The condensation section is located inside the heat dissipation mechanism, the insulation section is located at the lower end of the heat dissipation mechanism, the insulation section is connected to the monitoring and acquisition mechanism, and the lower end of the evaporation section is connected to the heating mechanism.
[0021] Furthermore, the siphon tube assembly can absorb liquid and convert it into a vaporized heat exchange medium for output, so that it can circulate within the siphon tube assembly. At the same time, it can also facilitate the stable directional flow of the heat exchange medium with magnetic beads within the siphon tube assembly by controlling the force of the movement of the heat exchange medium with magnetic beads.
[0022] Preferably, the heat exchange medium containing magnetic beads located in the evaporation section will change from a gaseous state to a liquid state;
[0023] The heat exchange medium containing magnetic beads located in the evaporation section transforms from a liquid to a vapor state.
[0024] Preferably, the heat dissipation mechanism can be a heat dissipation fin assembly, and the condensation section end of the pulsating heat pipe assembly is disposed through the heat dissipation fin assembly.
[0025] Furthermore, heat dissipation can be fully achieved through the heat dissipation fin assembly.
[0026] This invention also proposes a control method for an electromagnetically driven pulsating heat pipe cooling system, applicable to the aforementioned electromagnetically driven pulsating heat pipe cooling system, comprising the following steps:
[0027] S1. Component connection and installation: The staff will install the pulsed heat pipe assembly through the lower end of the heat dissipation and ventilation pipe, and install the electronically controlled pulse assembly inside the heat dissipation and ventilation pipe. At the same time, the axial flow cooling fan assembly will be installed at one end of the heat dissipation and ventilation pipe.
[0028] S2. Vacuuming and filling of heat exchange medium in the coil: Two connecting valves are installed on one side of the pulsating heat pipe assembly, and one of the valves is connected to the vacuum pump assembly, which can extract the air in the pulsating heat pipe assembly.
[0029] Another connecting valve can be connected to a filling pump, which can fill the pulsating heat pipe assembly with heat exchange medium containing magnetic beads. The heat exchange medium can be deionized water.
[0030] S3, Heating Circulation: The heat source component can heat up the heat absorber component, which facilitates heating the end of the pulsating heat pipe component away from the heat dissipation ventilation pipe. This causes the heat exchange medium in the section with magnetic beads to change from liquid to gas. At the same time, the gas moves towards the end of the pulsating heat pipe component located in the heat dissipation ventilation pipe. The axial flow cooling fan component can quickly make the gas flow in the heat dissipation ventilation pipe, which can dissipate heat from the end of the pulsating heat pipe component located in the heat dissipation ventilation pipe. At this time, the gaseous heat exchange medium will change into liquid and flow into the liquid suction pipe component. At the same time, the electronically controlled pulse component can be started intermittently to drive the magnetic beads to move in a direction, so that the magnetic beads can circulate in the pulsating heat pipe component.
[0031] S4. Detection Equipment Operation: Two temperature detection components installed on both sides of the lower end of the condensing section can accurately detect the temperature difference between the two ends and set the temperature difference value. At the same time, the standard deviation method is used for calculation. When the temperature difference value exceeds the set temperature difference, the PLC control component can control the corresponding electronically controlled directional pulse device to start automatically, so as to achieve stable flow of the heat exchange medium with magnetic beads. It can also control the operation of the electronically controlled directional pulse device according to the temperature difference to ensure stable flow of the heat exchange medium with magnetic beads.
[0032] Preferably, the standard deviation method includes the following steps:
[0033] First, calculate the mean (μ) and standard deviation (σ) of the dataset;
[0034] Second, assuming the data follows a normal distribution, according to the rule of thumb, approximately 99.7% of the data will fall within the interval [μ3σ, μ+3σ].
[0035] Third, the temperature difference is detected. If the temperature difference data point exceeds the range of [μ3σ,μ+3σ], the PLC control component 6 controls the electrically controlled directional pulse device 32 to start automatically.
[0036] The beneficial effects of this invention are:
[0037] 1. The axial flow cooling fan assembly enables the gas to flow rapidly, effectively removing heat from the surface of the condensing section and helping to significantly reduce the temperature within the condensing section; the siphon assembly absorbs liquid and converts it into a vaporized heat exchange medium for output, allowing it to circulate within the siphon assembly and facilitating stable directional flow of the heat exchange medium with magnetic beads within the siphon assembly.
[0038] 2. The heat source component enables the heat absorption plate component to operate, thereby raising the temperature of the heat exchange medium in the evaporation section. In actual production, the heat source component can be various heat source parts.
[0039] 3. Two temperature detection components installed on both sides of the lower end of the condensation section can accurately detect the temperature difference between the two ends and set the temperature difference value. When the temperature difference value exceeds the set temperature difference, the PLC control component can control the corresponding electronically controlled directional pulse device to start automatically, so as to achieve stable flow of the heat exchange medium with magnetic beads. It can also control the operation of the electronically controlled directional pulse device according to the temperature difference to ensure stable flow of the heat exchange medium with magnetic beads.

Detailed Implementation
[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0046] Reference Figure 1-4 An electromagnetically driven pulsating heat pipe cooling system includes a cooling mechanism, within which a pulsating heat pipe assembly 4 is installed. The lower end of the pulsating heat pipe assembly 4 extends through and to the lower end of the cooling mechanism. A heating mechanism is located at the lower end of the pulsating heat pipe assembly 4, and a monitoring and acquisition mechanism is connected to the middle of the pulsating heat pipe assembly 4. The heating mechanism enables the heating of the heat exchange medium with magnetic beads, while the cooling mechanism enables the cooling of the heat exchange medium with magnetic beads. Furthermore, the monitoring and acquisition mechanism allows for a comprehensive understanding of the temperature changes of the heat exchange medium within the pulsating heat pipe assembly 4, thus assessing the cooling effect.
[0047] In this embodiment, an electrically controlled pulse assembly 3 is installed inside the heat dissipation mechanism. The electrically controlled pulse assembly 3 consists of a mounting frame assembly 31 and multiple electrically controlled directional pulse devices 32. The multiple electrically controlled directional pulse devices 32 are installed on the mounting frame assembly 31 at equal intervals. The pulsating heat pipe assembly 4 is provided with multiple semi-circular arc-shaped pipes at one end inside the heat dissipation mechanism. The multiple electrically controlled directional pulse devices 32 are respectively arranged at the upper ends of the multiple semi-circular arc-shaped pipes. The pulsating heat pipe assembly 4 is provided with a heat exchange medium 45 with magnetic beads. The arrangement of the semi-circular arc-shaped pipes facilitates the flow of magnetic beads.
[0048] In this embodiment, the pulse direction of the electrically controlled directional pulse device 32 is consistent with the flow direction of the heat exchange medium 45 with magnetic beads, which can drive the magnetic beads to flow in the channel within the liquid suction tube assembly 44. At the same time, it can activate the mounting bracket assembly 31 to intermittently apply directional pulses, which can make the magnetic beads flow in a directional manner, avoid blockage, and thus effectively circulate and facilitate heating and heat dissipation operations.
[0049] In this embodiment, the heat dissipation mechanism includes a heat dissipation ventilation pipe 1, an axial flow heat dissipation fan assembly 2 is installed in the air outlet end of the heat dissipation ventilation pipe 1, and a mounting bracket assembly 31 is installed on the top inside the heat dissipation ventilation pipe 1; the axial flow heat dissipation fan assembly 2 enables the gas to flow rapidly, so as to effectively remove the heat from the surface of the condensation section 41, which helps to fully reduce the temperature inside the condensation section 41.
[0050] In this embodiment, the heating mechanism is installed on the heat-absorbing plate assembly 5 at the lower end of the pulsating heat pipe assembly 4, and a heat source assembly 8 is connected to one side of the heat-absorbing plate assembly 5. The heat source assembly 8 enables the heat-absorbing plate assembly 5 to operate so that the heat exchange medium in the evaporation section 43 can be heated. In actual production, the heat source assembly 8 can be a variety of devices that can generate heat and need to be cooled.
[0051] In this embodiment, the monitoring and acquisition mechanism includes multiple temperature detection components 7 installed on the pulsating heat pipe assembly 4. A PLC control component 6 is connected to one side of the multiple temperature detection components 7. The PLC control component 6 is connected to multiple electrically controlled directional pulse devices 32 to facilitate accurate detection of the temperature in each insulation section 42 of the pulsating heat pipe assembly 4. At the same time, it can calculate the temperature difference and transmit it to the PLC control component 6. The PLC control component 6 can also control the operation of the corresponding electrically controlled directional pulse device 32 according to the pre-input data. When the temperature difference is large, the electrically controlled directional pulse device 32 outputs a large value to ensure that the heat exchange medium 45 with magnetic beads can flow stably.
[0052] In this embodiment, the pulsating heat pipe assembly 4 includes a coil 46, within which a siphon tube assembly 44 is installed. A heat exchange medium 45 with magnetic beads is located within the siphon tube assembly 44. The siphon tube assembly 44 enables the circulation of the heat exchange medium. The pulsating heat pipe assembly 4 has, from top to bottom, a condensing section 41, an adiabatic section 42, and an evaporating section 43. The condensing section 41 is located within the heat dissipation mechanism, the adiabatic section 42 is located at the lower end of the heat dissipation mechanism and is connected to a monitoring and acquisition mechanism, and the lower end of the evaporating section 43 is connected to a heating mechanism. The siphon tube assembly 44 can absorb liquid and convert it into a vaporized heat exchange medium for output, allowing for circulation within the assembly. Simultaneously, it can exert force on the moving heat exchange medium 45 with magnetic beads, facilitating stable directional flow of the medium within the siphon tube assembly 44.
[0053] In this embodiment, the heat exchange medium 45 with magnetic beads located in the evaporation section 43 will change from a gaseous state to a liquid state; the heat exchange medium 45 with magnetic beads located in the evaporation section 43 will change from a liquid state to a gaseous state. Through the state change of the heat exchange medium, heating and heat dissipation cycles can be realized. At the same time, the gaseous heat exchange medium can make the magnetic beads flow in a directional manner.
[0054] In this embodiment, the heat dissipation mechanism can adopt a heat dissipation fin assembly. The condensation section 41 end of the pulsating heat pipe assembly 4 is installed through the heat dissipation fin assembly. The heat dissipation operation can be fully realized through the heat dissipation fin assembly. In actual production and preparation, the corresponding heat dissipation components can be selected as needed to quickly dissipate the temperature on the condensation section 41. This allows the gaseous state in the heat exchange medium 45 with magnetic beads to be converted into a liquid state so that the liquid can flow through the liquid suction pipe assembly 44.
[0055] In this invention, a control method for an electromagnetically driven pulsating heat pipe cooling system, applicable to the aforementioned electromagnetically driven pulsating heat pipe cooling system, includes the following steps:
[0056] S1.

[0059] S3, Heating Circulation: The heat source component 8 can heat up the heat absorber component 5, which is convenient for heating the end of the pulsating heat pipe component 4 away from the heat dissipation ventilation pipe 1. This causes the heat exchange medium in the section with magnetic beads to change from liquid to gas. At the same time, the gas will move towards the end of the pulsating heat pipe component 4 located in the heat dissipation ventilation pipe 1. The axial flow cooling fan component 2 can quickly make the gas in the heat dissipation ventilation pipe 1 flow, which can carry the heat exchange medium of the pulsating heat pipe component 4 located in the heat dissipation ventilation pipe 1 to dissipate heat. At this time, the gaseous heat exchange medium will change into liquid and flow into the liquid suction pipe component 44. At the same time, the electronic control pulse component 3 can be started intermittently to drive the magnetic beads to move in a direction, so that the magnetic beads can circulate in the pulsating heat pipe component 4.
[0060] S4. Operation of the detection equipment: The two temperature detection components 7 set on both sides of the lower end of the condensation section 41 can accurately detect the temperature difference between the two ends and set the temperature difference value.
