Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, and in particular to a freezing coil. Background Technology

[0002] Cryocoats, as devices that achieve rapid local cooling through a low-temperature medium, are widely used in medical cryotherapy, laboratory sample refrigeration, and local temperature control of industrial pipelines / equipment. Their core function is to uniformly transfer cold energy through contact with the target object and accelerate heat exchange through a heat dissipation structure, thereby achieving rapid freezing or temperature control.

[0003] Existing cryospheres typically employ a one-piece annular structure, which presents the following main problems:

[0004] Insufficient heat dissipation efficiency: The heat sinks of traditional cryogenic coils are mostly flat or unidirectionally bent, with limited heat exchange area and poor airflow, resulting in slow cold transfer speed and low freezing efficiency (for example, it takes more than 30 minutes to freeze a target object with a diameter of 100mm to -20℃).

[0005] Poor adaptability: The one-piece, notch-free structure makes the cryo-coil unsuitable for target objects of different diameters, requiring customization of various specifications, which increases the cost of use and operational complexity; although some designs with notches have a certain degree of flexibility, no reinforcement structure is set at the notches, making them prone to deformation or breakage after long-term use.

[0006] Insufficient structural strength and stability: To reduce weight, existing cryogenic coils often use thin-walled metal materials, which are prone to cracking due to thermal stress concentration in low-temperature environments; the interfaces connecting to external refrigeration devices are mostly single-hole designs, which pose a risk of cold air leakage and are inconvenient to install and disassemble.

[0007] Material selection limitations: Some products use low thermal conductivity materials such as stainless steel, resulting in low cold transfer efficiency; or they use pure copper, which has good thermal conductivity but is expensive and heavy, making it inconvenient to hold or move.

[0008] To address the aforementioned issues, the development of a cryocooler that combines efficient heat dissipation, structural stability, strong adaptability, and controllable cost has become an industry demand. This invention addresses the shortcomings of existing technologies, such as low freezing efficiency, insufficient structural reliability, and limited adaptability. By optimizing the heat sink structure, enhancing notch strength, improving connection methods, and selecting materials, it aims to provide a superior freezing device to meet the needs of medical, laboratory, and industrial fields for rapid, stable, and flexible freezing.

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 As shown, the embodiment of this utility model includes: a specific implementation of a freezer ring is as follows:

[0023] 1. Circle body 100

[0024] The ring body 100 is the core load-bearing structure of the cryogenic ring. It is circular in shape, with an outer diameter of 100-200mm, an inner diameter of 60-150mm, and a thickness of 2-5mm (e.g., 3mm). It is made of aluminum alloy or copper alloy, which has high thermal conductivity and low-temperature mechanical property stability. Its working principle is to ensure that the cold energy is quickly transferred to the entire ring body through the high thermal conductivity of the metal material. At the same time, the thickness design balances the structural strength and lightweight requirements, which can prevent embrittlement and fracture during temperature cycling from -40℃ to room temperature. The advantages of this design are high thermal conductivity and light weight, making it suitable for long-term low-temperature working scenarios. The outer edge of the ring body 100 is rounded to further prevent scratches to operators or adjacent parts during installation.

[0025] 2. Notch 200 and structural reinforcement component 300

[0026] The ring body 100 has a notch 200, which is arc-shaped or straight, with a width of 1 / 8 to 1 / 4 of the ring body 100's circumference. Its working principle is to provide radial elastic adjustment through the notch 200, allowing the ring to adapt to freezing targets of different diameters (such as pipes and container walls), avoiding localized stress concentration caused by rigid contact. To address the potential structural strength reduction caused by the notch 200, a structural reinforcement frame is provided at the notch 200. Its cross-section is U-shaped, with a depth of 5-10 mm, and its width matches the edge thickness of the notch 200. The structural reinforcement frame is integrally formed with the ring body 100 using a die-casting process or fixed by laser welding. The U-shaped cross-section disperses the stress at the notch 200, preventing low-temperature brittle fracture. The advantages of this structure are strong adaptability, a structural strength increase of over 40%, and a service life extended to over 5 years.

[0027] 3. Heatsink 400 structure

[0028] The inner ring has 4-12 heat sinks 400 evenly distributed circumferentially. Each heat sink 400 has a height of 5-15mm and a thickness of 1-2mm, and is set perpendicular to the plane of the ring body 100. The bending directions of adjacent heat sinks 400 are opposite (e.g., the first bends to the left, the second bends to the right, and they are arranged alternately), and the free end has a 30°-60° bend (preferably 45°), with a bending length of 2-3mm. Its working principle is that the heat sinks 400 with reverse bends form an "interlaced flow guiding structure". When the cold energy is transferred to the heat sinks 400 through the ring body 100, the bends can disturb the airflow boundary layer and guide the cold air to form vortices in the gaps between the heat sinks 400, increasing the heat exchange area (35% higher than that of flat heat sinks). The advantage of this design is that the heat dissipation efficiency is increased by 35%, the freezing efficiency can be increased by 25% under the -20℃ cooling condition, the cooling time of the target object is shortened, and the energy consumption is reduced by 20%.

[0029] 4. Connection Structure

[0030] The ring body 100 has 2-6 connecting holes 500, preferably 4, distributed at 90° intervals along the circumference, with a hole diameter of 3-8mm and a hole depth penetrating the thickness of the ring body 100; the inner wall of the connecting hole 500 is tapped with M5 threads for sealing connection with an external refrigeration device (such as the output interface of a cold nitrogen tank) via bolts (with fluororubber sealing rings, resistant to low temperatures of -60℃); its working principle is to achieve multi-point uniform cooling through multiple connecting holes 500, avoiding localized excessively low temperatures caused by a single connection (temperature difference ≤2℃), while the threaded connection facilitates quick disassembly and maintenance; the advantages of this structure are good temperature uniformity (temperature difference ≤2℃), convenient installation and disassembly (time ≤30 seconds), improving the ease of use and maintenance efficiency of the equipment.

[0031] The working principle of this technical solution is as follows: When the cryogenic ring is working, it is sealed to an external refrigeration device (such as a cold nitrogen tank) through the connection hole 500 on the ring body 100. The low temperature medium (such as -30℃ cold nitrogen gas) enters the internal flow channel of the ring body through the connection hole 500 (the internal flow channel can be designed according to the requirements), and is quickly transferred to the entire ring body through the high thermal conductivity of aluminum alloy / copper alloy. The reverse bending heat sink 400 of the inner ring guides the outside air to form turbulence through the staggered flow guiding structure, which accelerates the heat dissipation from the heat sink 400 to the environment, so that the surface temperature of the inner ring is rapidly reduced to the target value (such as -25℃). The notch 200 design allows the ring body to shrink slightly at low temperature (radial shrinkage ≤0.5mm), avoiding thermal stress concentration, while the structural reinforcement frame ensures that the strength at the notch 200 meets the requirements of repeated loading and unloading and temperature cycling.

[0032] The advantages of this technical solution are:

[0033] High-efficiency freezing: The combination of reverse-bent heat sink 400 and multi-point cooling improves freezing efficiency by 25%, making it suitable for rapid freezing of precision items such as medical samples and electronic components;

[0034] Structural stability: The U-shaped reinforcing frame and the one-piece molding process solve the strength problem of the notch 200, and can withstand ≥500 temperature cycles (-40℃ to room temperature) without damage;

[0035] Highly adaptable: The 200mm notch with flexible adjustment function can accommodate target objects with diameter differences of ±10mm, eliminating the need to replace freezing rings of different specifications;

[0036] Low energy consumption and long lifespan: High thermal conductivity materials and optimized heat dissipation structure reduce the power requirements of the refrigeration unit (energy saving of 20%), while metal materials and sealed design ensure a service life of ≥5 years.

[0037] In summary, this utility model achieves efficient, stable, and highly adaptable freezing functions through structural optimization and material selection, and can be widely used in medical, laboratory, and industrial refrigeration fields.
