Description

Technical Field

[0001] The utility model relates to the technical field of furniture products, in particular to an enhanced heat exchange system for a medical refrigerator. Background Art

[0002] The enhanced heat exchange system for medical refrigerators is a highly efficient heat exchange device designed specifically for medical refrigerators. It ensures a stable and suitable low-temperature environment inside the refrigerator to meet the stringent storage temperature requirements of medical supplies, pharmaceuticals, biological samples, and more. In the medical field, the reliability and cooling performance of medical refrigerators are directly related to the quality and safety of medical work. An efficient heat exchange system not only provides rapid cooling but also precisely controls temperature, reducing temperature fluctuations, thereby ensuring the quality and effectiveness of stored items.

[0003] Existing medical refrigerator heat exchange systems usually include main components such as refrigeration compressors, condensers, evaporators, throttling devices, and connecting pipes. Its working process is roughly as follows: the refrigeration compressor compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas, and then discharges it into the condenser. In the condenser, the refrigerant gas is cooled and condensed into a high-pressure liquid through heat exchange with the external environment. After the high-pressure liquid is reduced in pressure by the throttling device, it becomes a low-temperature, low-pressure gas-liquid mixture and enters the evaporator. In the evaporator, the refrigerant absorbs the heat inside the medical refrigerator and evaporates into a gas, thereby achieving refrigeration inside the refrigerator. Afterwards, the low-temperature, low-pressure refrigerant gas is sucked into the refrigeration compressor again and a new cycle begins. The entire process continuously transfers the heat in the refrigerator to the external environment through the state change of the refrigerant to maintain the low temperature state inside the refrigerator;

[0004] In the prior art, the installation and fixing methods of the delivery pipes of medical refrigerators usually adopt traditional methods such as bolt connection. This method has obvious disadvantages when the equipment needs to disassemble and clean the inner wall of the delivery pipe. Since the internal space of medical refrigerators is often relatively compact and there may be other components or structures around, when it is necessary to use specific tools to remove the bolts on the outer wall of the delivery pipe, it is easily blocked by surrounding components. This not only makes the disassembly operation difficult, requiring a lot of time and energy to find the right operating space and angle, but also because of the inconvenience of operation, the bolts cannot be removed smoothly, which seriously hinders the disassembly of the delivery pipe and affects the maintenance efficiency and normal use of the equipment. For this reason, an enhanced heat exchange system for medical refrigerators is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an enhanced heat exchange system for medical refrigerators, which aims to improve the problem that when the equipment disassembles and cleans the delivery pipe, it is necessary to use specific tools to remove the bolts on the outer wall of the delivery pipe, which is easily blocked by surrounding components during disassembly, thereby hindering the disassembly of the delivery pipe.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an enhanced heat exchange system for a medical refrigerator, comprising a connecting shell 1, one side of the connecting shell 1 is fixedly connected to an air inlet pipe 2, the other side of the connecting shell 1 is fixedly connected to an air outlet pipe 3, a plurality of connecting pipes 5 are fixedly connected inside the connecting shell 1, and the connecting pipe 5 brackets on both sides are slidably connected to a delivery pipe 4, the delivery pipe 4 is made of high-strength aluminum alloy, the inner wall of which is specially anti-corrosion treated and smooth coated, the outer wall of the delivery pipe 4 is provided with a quick-install component, the quick-install component is used for portable installation and removal of the delivery pipe 4, the outer wall of the connecting shell 1 is provided with a refrigeration component, the refrigeration component is used to enhance the refrigeration effect of the equipment;

[0035] The quick-release assembly includes multiple blocks 7, which are arranged at both ends of the delivery pipe 4. The blocks 7 are made of wear-resistant alloy steel and are in the shape of a rectangular parallelepiped. One end is designed with a convex structure that matches the internal groove of the delivery pipe 4 for clamping the delivery pipe 4. Both ends of the blocks 7 are fixedly connected to a limit ball 8. The outer wall of the limit ball 8 is slidably connected to a connecting pipe 2 12. The connecting pipe 2 12 is fixedly connected to the inner wall of the connecting shell 1. The outer wall of the connecting pipe 2 12 is slidably connected to a baffle 9. The baffle 9 is disc-shaped and made of stainless steel. Its edge is finely polished to ensure that it fits tightly with the outer wall of the connecting pipe 2 12 during the sliding process and the friction is moderate, so that there will be no jamming or excessive wear. One side of the baffle 9 is fixedly connected to a spring 10, and one side of the spring 10 is fixedly connected to a fixing ring 11. The fixing ring 11 is fixedly connected to the outer wall of the connecting pipe 2 12. Sponge pads 6 are provided at both ends of the delivery pipe 4. The sponge pads 6 are made of high-density polyurethane sponge and have good resilience and compressibility. Its thickness and hardness are moderate, which can provide sufficient compression space when squeezed by the conveying pipe 4, and can quickly return to its original shape after the pressure disappears. The sponge pad 6 is fixedly connected to the inner wall of the connecting shell 1, and the baffle 9 is set on the outer wall of the block 7.

[0036] Specifically, in the process of disassembling the delivery pipe 4, it is first necessary to slide the baffle 9 on the outer wall of the connecting pipe 2 12. During the movement of the baffle 9, the spring 10 connected thereto is compressed. When the baffle 9 moves to one side, the spring 10 is gradually compressed to store elastic potential energy. Then, one end of the delivery pipe 4 is moved out from the outer wall of the baffle 9 on one side. The outer diameter of the delivery pipe 4 matches the inner diameter of the baffle 9, so that the delivery pipe 4 can move relatively smoothly in the baffle 9. At the same time, the other end of the delivery pipe 4 squeezes the sponge pad 6. When one end of the delivery pipe 4 is inside When the groove on the outside of the block 7 is removed from the outer wall of the block 7, it will drive the limiting ball 8 on the outer wall of the block 7 to slide inside the connecting pipe 2 12. The limiting ball 8 effectively prevents the block 7 from accidentally falling out of the connecting pipe 2 12 during movement. By separating the grooves on both sides of the delivery pipe 4 from the outer wall of the block 7, the delivery pipe 4 can be smoothly disassembled. After disassembly, it is convenient to thoroughly clean the dust and dirt on the inner wall of the delivery pipe 4, ensuring that the gas can flow quickly and unimpeded inside the delivery pipe 4. After cleaning, the block 7 is similarly re-engaged in the groove inside the delivery pipe 4. During installation, it is necessary to ensure that the protrusion of the block 7 is accurately embedded in the groove of the delivery pipe 4. Then, the two ends of the delivery pipe 4 are aligned with the corresponding positions of the baffle 9 and the connecting pipe 2 12, and the delivery pipe 4 is pushed to compress the sponge pad 6 again. At the same time, the baffle 9 is gradually reset under the elastic force of the spring 10 until the delivery pipe 4 is installed in place. This operation method realizes the rapid installation and fixation of the delivery pipe 4, improving the installation and removal efficiency of the delivery pipe 4.

[0037] Reference Figure 4 - Figure 5 The refrigeration component includes a fan 18, which is arranged on the outer wall of the connecting shell 1, and a slide groove 21 is opened on both sides of the interior of the connecting shell 1. The outer wall of the slide groove 21 is slidably connected with a slider 15, and the slider 15 is made of wear-resistant engineering plastic, has a smooth surface and has a certain self-lubricating property, and can slide smoothly on the inner wall of the slide groove 21. The inner wall of the connecting shell 1 is fixedly connected with a connecting plate 19, and a limiting column 22 is opened inside the connecting plate 19. One side of the connecting shell 1 is fixedly connected with a fixed block 13, and the fixed block 13 is fixedly connected with an electric telescopic rod 14. The output end of the electric telescopic rod 14 is fixedly connected to the outer wall of the slider 15 on one side. A limiting bar 16 is fixedly connected between the sliders 15 on both sides. The limiting bar 16 is made of aluminum alloy, has certain strength and light weight, and can accurately transmit the movement of the slider 15. The outer wall of the limiting bar 16 is slidably connected with a protective shell 17, and the protective shell 17 is fixedly connected with a fan 18. One side of the fan 18 is fixedly connected with a limiting column 22, and the limiting column 22 is slidably connected to the inner wall of the slide groove 20.

[0038] Specifically, during the normal operation of the device, the cold air after the refrigeration treatment enters the interior of the connecting shell 1 through the air inlet pipe 2, and the cold air then circulates inside the delivery pipe 4. However, during the circulation of the cold air inside the delivery pipe 4, it is inevitable that some of the cold air will be emitted outward through the delivery pipe 4. At this time, in order to make full use of this part of the emitted cold air, the electric telescopic rod 14 is started, and the output end of the electric telescopic rod 14 is used to drive the slider 15 on one side to slide on the inner wall of the slide groove 21. The movement of the slider 15 on one side drives the limit bar 16 to move synchronously, and the limit bar 16 moves at the same time. When the protective shell 17 is in operation, the fan 18 will be driven by the protective shell 17 to slide along the track of the inner wall of the slide groove 20. During the movement, the fan 18 will drive the limiting column 22 to slide on the inner wall of the slide groove 20, ensuring that the fan 18 moves accurately along the track of the inner wall of the slide groove 20. At this time, the protective shell 17 will also start to slide synchronously on the outer wall of the limiting bar 16, and the cold air emitted from the outer wall of the delivery pipe 4 will be blown into the interior of the medical refrigerator through the fan 18, thereby making full use of this part of the cold air, enhancing the refrigeration effect of the equipment on the medical refrigerator, improving the refrigeration efficiency, and providing a more stable and efficient refrigeration environment for the medical refrigerator.

[0039] Working principle: During the disassembly of the delivery pipe 4, the baffle 9 is slid on the outer wall of the connecting pipe 2 12 to provide space for the block 7 to move. During the movement, the baffle 9 drives the spring 10 to be compressed, and then one end of the delivery pipe 4 is moved out from the outer wall of the baffle 9 on one side. At the same time, the other end of the delivery pipe 4 squeezes the sponge pad 6, and the compressible characteristics of the sponge pad 6 are used to provide space for the movement of the delivery pipe 4. When the internal groove at one end of the delivery pipe 4 moves out from the outer wall of the block 7, it drives the limiting ball 8 on the outer wall of the block 7. When the air is exhausted, the air in the airtight container 1 is opened, and ... At the same time as the movement, the protective shell 17 will drive the fan 18 to slide along the trajectory of the inner wall of the slide groove 20. During the movement, the fan 18 will drive the limiting column 22 to slide on the inner wall of the slide groove 20, thereby limiting the movement of the fan 18 and ensuring that the fan 18 moves along the trajectory of the inner wall of the slide groove 20. At this time, the protective shell 17 will also start to slide synchronously on the outer wall of the limiting bar 16, and the cold air emitted from the outer wall of the delivery pipe 4 will be blown into the interior of the medical refrigerator through the fan 18, thereby enhancing the refrigeration effect of the equipment on the medical refrigerator.
