Description

Technical Field

[0001] This invention relates to the field of instrumentation and control technology, and more specifically to a constant temperature heat dissipation control system based on memristors. Background Technology

[0002] Thermal control systems are widely used in various fields such as instrumentation, computer applications, and chemical engineering. In recent years, with the rapid development of various high-precision, nanoscale integrated circuit technologies, the demand for high-precision instruments and equipment has been increasing daily, indicating that the heat dissipation conditions for such equipment are becoming increasingly stringent, and the requirements for constant-temperature heat dissipation are also becoming higher. Existing heat sinks are mostly water-cooled or air-cooled. First, based on the inherent physical properties of the equipment, water cooling cannot guarantee the airtightness of the control system during long-term use, because the ambient temperature will cause frost or water vapor to condense on the surface of the water-cooled system. Although this type of heat dissipation mechanism has good constant-temperature characteristics, it is not suitable for the electrical and electronic fields, especially for the heat dissipation systems of instruments and equipment with high-precision characteristics. Second, air cooling mostly uses aluminum profiles, with single multi-aluminum fins and high-power fans. Although it can effectively remove heat from the surface of the aluminum fins, it is difficult to maintain a constant temperature environment, and it does not have a temperature memory function. After the system is turned on, it takes a considerable amount of time to achieve the purpose of heat dissipation. The above heat dissipation methods not only reduce the service life of high-precision equipment and increase maintenance risks, but may even directly damage critical components, resulting in incalculable losses. Meanwhile, during the heat dissipation and temperature adjustment process of high-precision equipment, high-power devices generate more heat, bringing noise and interference to the system.

[0003] Therefore, how to achieve rapid and constant temperature heat dissipation for high-precision equipment, reduce equipment maintenance risks, and extend service life is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] This invention discloses a constant temperature heat dissipation control system based on memristors, such as... Figure 1 As shown, the device includes a constant temperature heat dissipation control circuit and a heat sink. The constant temperature heat dissipation control circuit includes a power conversion circuit, a temperature detection circuit, a comparator circuit, a memristor emulator, a low-pass filter module, and an electromagnetic compatibility module. The heat sink includes an adjustable speed fan 22. The power conversion circuit is electrically connected to the electromagnetic compatibility module, the low-pass filter module, the temperature detection circuit, and the adjustable speed fan 22. The temperature detection circuit and the memristor emulator are connected to the input terminal of the comparator circuit, the output terminal of the comparator circuit is connected to the adjustable speed fan 22, and the adjustable speed fan is connected to the memristor emulator.

[0033] The constant temperature heat dissipation control circuit organically combines a power conversion circuit, a temperature detection circuit, a comparison circuit, a memristor simulator, a low-pass filter module, and an electromagnetic compatibility module to automatically control the heat sink's operation. It achieves both constant temperature heat dissipation and offline memory functionality, ensuring that the cooling system of high-precision instruments can quickly reach and stabilize at the predetermined temperature value after power-on. This avoids serious consequences such as damage caused by repeated power-on and power-off cycles leading to substandard temperatures in high-precision instruments, reducing maintenance risks and extending service life.

[0034] (1) Power conversion circuit, connected to 220V, 50Hz mains power supply; can provide ±15V drive voltage for the operational amplifier of the temperature detection circuit, and provide working voltage (VCC) for the transistor, etc. For this purpose, it provides multiple level types and voltage values ​​for the entire control system, and systematically manages the power supply of the entire circuit, including the subsequent low-pass filter module and electromagnetic compatibility module, so as to filter out high-frequency signals such as Gaussian white noise, high-frequency noise, 1 / f noise generated in the circuit due to various reasons, and ensure the safety and service life of the system and high-precision instruments.

[0035] (2) Temperature detection circuit, including acquisition and voltage regulation module. During the operation of high-precision instruments, to prevent false sampling (i.e., the acquired temperature is only the real-time temperature of a certain component and cannot represent the current temperature of the entire device), a thermistor is used to acquire the operating temperature signal of the high-precision instrument in real time using a multi-point sampling method, and convert it into a detection temperature voltage (V). TThe voltage signal is transmitted to the operational amplifier via a sampling conversion circuit. The operational amplifier then outputs a voltage signal through a PNP transistor to achieve a stable output temperature detection voltage, which is then transmitted to the comparator circuit. The output voltage (V) of the temperature sampling module is then used to... T ) and the memory temperature voltage (V) output by the memristor emulator m In comparison, by adjusting the resistance value of the sliding rheostat R13 of the adjustable speed fan 22, the speed of the adjustable speed fan 22 in the heat sink can be controlled, ultimately ensuring that the system operates stably under constant temperature heat dissipation conditions.

[0036] (3) The memristor emulator utilizes memristors i m -V m The hysteresis property of the output curve is stored as a memory voltage, which serves as the reference voltage for the comparator. This voltage is compared with the acquired temperature voltage, and in conjunction with the adjustable-speed fan 22, the control system achieves constant-temperature cooling. Since the memristor's information storage depends on the system's operating voltage and frequency, the memristor simulator in this invention is directly connected to mains power and does not have any built-in voltage source. Therefore, there is no information loss, achieving the purpose of temperature memory.

[0037] Furthermore, both the upper housing 1 and the lower housing 2 are cylindrical, with an air outlet 21 on the side wall of the lower housing 2; the constant temperature heat dissipation control circuit is located inside the upper housing 1, and the heat sink is located inside the lower housing 2; the upper housing 1 and the lower housing 2 are detachably connected. Figure 2 As shown, the entire system has a cylindrical structure, consisting of two parts: the circuit section and the air-cooled mechanical section. The two parts are connected separately for easy maintenance and replacement of parts. The left side of the equipment, near the circuit section, is powered by 220V, 50Hz AC mains. The right side, near the sorting section, has the air outlet (or heat dissipation vent) for cooling by the fan and aluminum heat sink.

[0038] Furthermore, the heat sink also includes several heat sink fins 23, which are distributed around the adjustable speed fan 22; all heat sink fins 23 have pads on the same side surface, and the pads are located at the rear of the heat sink. Figure 3As shown, the heat sink is designed in a cylindrical shape, employing a mechanical heat sink fin design surrounding a centrally located adjustable cooling fan to achieve circulating heat dissipation. When the internal temperature of the controller is higher than the memory value, the fan accelerates; conversely, the fan operates at a low speed; when the temperature is the same as the memory value, the fan operates at a constant speed, achieving the purpose of constant temperature control. The heat dissipation section consists of a centrally located adjustable-speed fan and a high-power drive circuit. The fan is surrounded by eight aluminum heat sink fins using a circulating heat dissipation mechanical design. Considering thermodynamics, fluid mechanics, and aerodynamics, excessively high airflow speeds during system heat dissipation can generate air vortices or chaotic phenomena. Therefore, a small pad is installed on each heat sink fin to introduce a disturbance to the flowing air, breaking the initial conditions for the formation of air vortices or chaos, reducing the nonlinear effects in the airflow heat transfer process, and ensuring the stable operation of the air circulation heat dissipation process.

Its main characteristic is that the current (i) is... m ) and voltage (V m The hysteresis curve of the memristor is shown. Meanwhile, as a candidate to replace the von Neumann computer architecture, the memristor has become an essential component for researching memory systems and brain-like systems. This embodiment utilizes its memory and storage characteristics to apply it to the air-cooled constant-temperature heat dissipation system of high-precision instruments, which has rich theoretical and engineering significance and broad market prospects. However, as a nanoscale circuit element, the complex nanoscale manufacturing process of the memristor severely restricts its commercial and engineering applications. Therefore, this embodiment adopts the design method of a memristor simulator. Based on the inherent physical characteristics of diodes, a hyperbolic function with fixed frequency characteristics is constructed using two diodes and an LC second-order oscillator circuit. Then, an inverting operational amplifier is used to realize the design of a passive memristor simulator.

[0044] memristor emulator i m -V m Features such as Figure 5 As shown, the horizontal axis represents current, and the vertical axis represents voltage. CH1 = 100mA / Div means that one division on the oscilloscope's CH1 channel waveform represents 100mA on the X-axis, and CH2 = 500mV / Div means that one division on the oscilloscope's CH2 channel waveform represents 500mV on the Y-axis. As can be seen from the figure, based on the operating characteristics of the memristor emulator, which is also its fingerprint characteristic, i.e. m -V m The curve exhibits hysteresis characteristics, indicating that the constructed memristor simulator is realistic and reliable, further verifying that the present invention is a control method with memory storage properties.
