Description

Technical Field

[0001] This utility model provides a heat dissipation device, belonging to the technical field of superconducting filter equipment, and particularly relates to a heat dissipation device for superconducting filter circuits. Background Technology

[0002] Superconducting filters are key devices that utilize the near-zero resistance of superconducting materials at specific low temperatures to achieve high-performance signal transmission and filtering, and have important applications in many fields such as communications and radar. However, existing heat dissipation devices for superconducting filter circuits have significant shortcomings. Common heat dissipation devices often employ simple shell structures, such as ordinary enclosed housings, with messy internal circuit layouts and a lack of effective circuit limiting structures. This makes the circuits prone to tangling and interference, affecting signal transmission stability and thus reducing the performance of the superconducting filter. Moreover, their heat dissipation structure design is relatively simple, often just adding a fan or simple heat sink to the shell, which cannot efficiently dissipate the heat generated by the circuit. When the superconducting filter circuit operates under high load for a long time, heat continues to accumulate, making it difficult to maintain the low-temperature environment required by the superconducting device, seriously affecting the working performance of the superconducting filter, and even causing failure and shortening its service life.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2As shown, a heat dissipation device for a superconducting filter circuit includes a cylindrical supporting shell, a transparent glass-like cylindrical upper protective shell, a circuit limiting shell, and a heat dissipation structure. The supporting shell is closed at the bottom and open at the top, used to support the superconducting filter; the transparent glass-like upper protective shell is closed at the top and open at the bottom, covering the top of the supporting shell, and the two are connected by bolts to form a closed cavity; the circuit limiting shell is located inside the supporting shell, in a grid or frame shape, used to organize the superconducting filter circuit; the heat dissipation structure is located inside the transparent glass-like upper protective shell, with the upper end of the circuit inserted therein, and the supporting shell and the circuit limiting shell are penetrated by the circuit. An external expansion interface electrically connected to the circuit is provided at the bottom of the supporting shell, and limiting plates are provided at both ends of the heat dissipation structure, which, together with the circuit limiting shell, realize the limiting and guiding of the circuit.

[0026] In this implementation scheme, the supporting outer shell and the transparent glass-like upper protective shell are detachably connected by bolts. This not only facilitates the installation and maintenance of the superconducting filter circuit, but also effectively isolates external interference, ensuring stable circuit operation. The grid-like or frame-like circuit limiting shell precisely confines the circuit within a specific area. By standardizing the circuit routing, it greatly reduces entanglement and electromagnetic interference between circuits, significantly improving signal transmission stability. The spiral or serpentine coiled loop tubes within the heat dissipation structure are tightly fitted to the superconducting filter circuit. With the help of circulating cooling medium, the heat dissipation contact area is greatly increased, enabling rapid and efficient removal of heat generated during circuit operation. This effectively maintains the low-temperature environment required for superconducting devices, ensuring the performance of the superconducting filter. The external expansion interface at the bottom of the housing provides a convenient electrical connection for the circuit, facilitating integration with other devices. Meanwhile, the limiting plates at both ends of the heat dissipation structure work in conjunction with the circuit limiting housing to limit and guide the circuit from both the top and bottom, ensuring that the circuit is fixed in position within the device and preventing circuit displacement due to vibration or other factors. This further improves the reliability and stability of the entire device, effectively solving problems such as poor heat dissipation, disordered wiring, and unstable installation in existing technologies, and achieving efficient and stable operation of the superconducting filter circuit.

[0027] like Figure 3 and Figure 4 As shown, in the heat dissipation device for the superconducting filter circuit, the core component of the heat dissipation structure is a loop tube sleeved outside the superconducting filter circuit. The loop tube is spiral or serpentine, with a cooling medium circulating inside to carry away the heat from the circuit. The circuit limiting shell arranges the circuit inside the supporting shell. The supporting shell and the transparent glass-like upper protective shell are fixed by bolts. The limiting plates at both ends of the heat dissipation structure and the circuit limiting shell work together to accurately limit and guide the superconducting filter circuit, ensuring heat dissipation and stable circuit operation.

[0028] In this implementation scheme, during actual use, the device utilizes a circulating cooling system connected to the loop pipe within the heat dissipation structure. The circulating cooling system continuously pumps a low-temperature cooling medium into the loop pipe via pipelines. After the loop pipe absorbs heat from the superconducting filter circuit and heats up, it flows back to the circulating cooling system for cooling, creating a circulating flow of the cooling medium to ensure effective heat dissipation. Simultaneously, the bolted connection between the supporting outer shell and the transparent glass-like upper protective shell can employ existing anti-loosening bolts to prevent loosening due to vibration during operation. The supporting outer shell can be made of aluminum alloy, utilizing its lightweight and high thermal conductivity to aid heat dissipation. The transparent glass-like upper protective shell is made of high borosilicate glass, a material with excellent light transmittance, high strength, and high-temperature resistance, facilitating observation of the internal circuitry and ensuring structural strength. The circuit limiting shell is made of insulating engineering plastics, such as polycarbonate, which helps to organize the circuitry while preventing short-circuit risks. This combination with existing technologies and materials makes the entire heat dissipation solution more complete and reliable.

[0029] Specifically, during installation, existing positioning fixtures can be used to assist in placing the circuit limiting housing, precisely installing it in the center of the inner casing to ensure the superconducting filter circuit is properly installed. Using an electric screwdriver, the inner casing and the transparent glass-like upper protective shell are secured with anti-loosening bolts using a diagonal tightening method, ensuring the sealing and stability of the enclosed cavity. The circuit pipes within the heat dissipation structure can be reliably connected to the inlet and outlet pipes of the circulating cooling system using existing welding processes, such as argon arc welding. The circulating cooling system employs mature temperature control technology, using PID regulation to control the temperature and flow rate of the cooling medium. When the system detects an increase in the temperature of the cooling medium in the circuit pipes, it automatically adjusts the cooling equipment to increase the cooling capacity and accelerate the speed of the circulating pump, rapidly cooling the cooling medium and accelerating its circulation to efficiently remove heat from the circuit. The external expansion interface uses existing standardized electrical connector interfaces. Following the corresponding pin definitions, crimping pliers are used to firmly connect the circuit wires to the electrical connector terminals before plugging the electrical connector to the external expansion interface, achieving a stable electrical connection between the circuit and external devices. During the operation of the device, existing vibration monitoring equipment can be used to monitor the overall vibration of the device in real time. If abnormal vibration occurs, the device should be stopped immediately to check whether the bolt connections are loose or whether the circuit limit switches are displaced, so as to ensure the safe and stable operation of the device.

[0030] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
