Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration devices, and particularly to an energy-saving and efficient refrigeration device for medical cryogenic instruments. Background Art

[0002] A refrigeration device for medical cryogenic instruments is a device specifically designed to store or process medical instruments in a low-temperature environment, aiming to inhibit bacterial growth, extend the sterile state of instruments, or assist specific medical techniques by controlling the temperature.

[0003] In the process of using existing refrigeration devices for medical cryogenic instruments, the overall space refrigeration method is generally adopted, that is, after starting, the compressor and evaporator cooperate to continuously cool the entire internal cavity to maintain the set temperature environment. This design can meet the usage requirements when a large number of instruments or samples need to be cooled. However, in actual applications, the medical scenario has significant operational flexibility and randomness in the use of instruments. During some periods, only a small number of instruments or a single container need to be cooled. At this time, the device will still perform refrigeration operation on the entire internal space, resulting in the system maintaining an unnecessary low-temperature state for a long time, thereby causing continuous consumption of electric energy and frequent operation of system components, significantly reducing the energy utilization efficiency, and also increasing the mechanical wear and maintenance frequency of refrigeration components. From the perspective of energy conservation, when the volume of the cooling target is much smaller than the volume of the refrigeration space, most of the cold energy required to maintain the low temperature is used to cool the air in the cavity and the unused area. This heat exchange process is not only inefficient but also leads to unreasonable energy distribution. Therefore, existing refrigeration devices for medical cryogenic instruments have significant energy waste problems when dealing with a small amount of cooling requirements, and cannot flexibly adjust the refrigeration range and operating state according to the number of cooling targets, restricting the further optimization space of such devices in terms of energy conservation and efficient use.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-8, an energy-saving and efficient medical low-temperature device refrigeration apparatus, comprising: a housing 1, which is used to form the external structural framework of the entire refrigeration apparatus, form a sealed space to isolate the interference of external hot air on the internal environment, and provide installation support and thermal insulation functions for internal components; a door 2, the door 2 is arranged on the front of the housing 1, and the door 2 is used as a structural member for entering and exiting the refrigerated cavity, mainly for opening and closing control, placing and taking out instruments. Its position is arranged on the front, which is convenient for users to operate and improves the human-machine interaction experience. At the same time, a sealing strip structure is arranged on the door 2 to improve the overall airtightness and prevent cold air from leaking; a refrigeration mechanism 3, the refrigeration mechanism 3 is arranged on the inner wall of the housing 1, and the refrigeration mechanism 3 is used to form a stable cold air environment in the inner wall area of the housing 1, and quickly reduce the cavity temperature by means of compressor refrigeration, evaporator 35 cooling, etc., to ensure the safe storage of medical devices within a limited temperature range, which helps to extend the service life of the devices and reduce the risk of bacterial growth; a partition mechanism 4, the partition mechanism 4 is arranged on the inner wall of the housing 1, and the partition mechanism 4 is used to form multiple partitions in the housing 1, and each partition is provided with an openable and closable closed structure. In the closed state, it is used to block the upward flow of cold air at the bottom, so as to flexibly control the refrigeration area according to storage requirements, reduce the overall energy consumption, improve the local cooling efficiency and prevent temperature interference; a circulation mechanism 5, the circulation mechanism 5 is arranged on the inner wall of the housing 1, and the circulation mechanism 5 is used to circulate and transport the cold air generated by the refrigeration mechanism 3, realize the uniform flow of cold air between each partition, maintain the consistency of temperature distribution, effectively prevent the problem of uneven cold air distribution, and improve the overall refrigeration performance and heat exchange efficiency.

[0021] The refrigeration mechanism 3 includes heat dissipation holes 31 and a connecting pipe 38. The heat dissipation holes 31 are arranged on the outer wall of the housing 1 to achieve timely discharge of the heat generated inside, avoiding the influence of equipment temperature rise on the refrigeration efficiency. A compressor device 32 is fixedly connected to the inner wall of the housing 1, which is used to compress and transport the refrigerant and is the power core of the entire refrigeration cycle system. A hollow baffle 33 is arranged on the inner wall of the housing 1. An insulating layer 34 is provided on the inner wall of the hollow baffle 33. An evaporator 35 is fixedly connected to the inner wall of the hollow baffle 33. A radiator 36 is fixedly connected to the inner wall of the housing 1. A fan 37 is arranged on the inner wall of the hollow baffle 33, which is used to drive the cold air to circulate along the channel, so that the cold air can be quickly distributed to each area of the refrigeration cavity, improving the cooling efficiency and response speed. The compressor device 32 is connected to the radiator 36 through the connecting pipe 38. The compressor device 32 is connected to the evaporator 35. The evaporator 35 is connected to the radiator 36 through the connecting pipe 38. The compressor device 32 is simultaneously connected to the evaporator 35 to form a complete closed refrigeration circuit, and a condensation path is formed with the radiator 36 through the connecting pipe 38, constructing a standard refrigeration cycle process from compression, condensation, throttling to evaporation. The high-temperature and high-pressure gaseous refrigerant is transported to the radiator 36 for heat exchange and condensed into a liquid state. Subsequently, the liquid refrigerant enters the evaporator 35 through the connecting pipe 38, absorbs heat and quickly evaporates in the evaporator 35 to achieve the cooling effect. The evaporator 35 is fixedly arranged on the inner wall of the hollow baffle 33. The hollow baffle 33 constructs an independent cooling channel, and an insulating layer 34 is provided on its inner wall to isolate the hot air flow and the cold air flow, improving the cold quantity concentration and reducing the heat interference. The compressor device 32 includes a compressor body 321. A controller 322 is arranged on the top of the compressor body 321, which is used to control the start and stop of the compressor body 321, adjust the operating frequency and manage the refrigeration cycle state. A temperature sensor 323 is fixedly connected to the top of the controller 322. The temperature sensor 323 is located inside the hollow baffle 33 and is used to collect the temperature data inside the refrigeration cavity in real time and feedback it to the controller 322 for intelligent temperature control adjustment, ensuring that the refrigeration system operates stably within the set temperature range, avoiding over-refrigeration or temperature fluctuations, and achieving the comprehensive goals of energy saving and precise temperature control. There are two groups of heat dissipation holes 31, and the two groups of heat dissipation holes 31 are symmetrically arranged front and back on the housing 1. By arranging two groups of symmetrically arranged heat dissipation holes 31 on the housing 1, it can ensure that the heat is evenly discharged on both sides of the inner wall of the housing 1, thereby avoiding local overheating of the equipment and improving the overall heat dissipation efficiency. This symmetrical design can effectively avoid the temperature on one side being too high due to heat accumulation, thus affecting the normal operation of the equipment. The symmetrically arranged heat dissipation holes 31 contribute to the balance of air flow and the convection process. By evenly discharging heat, it improves the fluidity and heat dissipation effect of the external air, helps to accelerate the uniform distribution of the internal temperature, prevents the accumulation of condensate or moisture, and thus improves the stability and service life of the device.

[0022] The partition mechanism 4 includes a hollow through plate 41, which is fixedly connected to the inner wall of the housing 1. The inner wall of the hollow through plate 41 is hollow, and the upper and lower parts of the hollow through plate 41 are through grooves. A first spring 42 is arranged on the inner wall of the hollow through plate 41. One end of the first spring 42 is fixedly connected to the inner wall of the hollow through plate 41, and the other end of the first spring 42 is fixedly connected to a connecting disc 43. A sealing plate 44 is fixedly connected to the outer wall of the connecting disc 43. A connecting rod 48 is fixedly connected to the inner wall of the connecting disc 43, and the outer wall of the connecting rod 48 is slidably connected to the inner wall of the hollow through plate 41. When the bottom fan 37 blows cold air upward, it will pass through the upper and lower through grooves of the hollow through plate 41 and impact the sealing plate 44 inside the hollow through plate 41, so that the cold air bypasses the sealing plate 44 and is discharged through the through groove at the top of the hollow through plate 41. Such a design can effectively delay the upward speed of the cold air, make the internal air flow slow down, prevent the internal space from being blown by the cold air at too fast a speed, avoid the internal space from being disturbed by the rapid impact of the cold air, and reduce the possibility of the strong cold wind directly impacting the storage area. A first inclined groove semi-circular block 45 is fixedly connected to the top of the sealing plate 44. A second inclined groove semi-circular block 46 is rotatably connected to the inner wall of the hollow through plate 41. A rotating knob 47 is fixedly connected to the top of the second inclined groove semi-circular block 46. Multiple sets of partition mechanisms 4 are provided, and the multiple sets of partition mechanisms 4 divide the space inside the housing 1 into multiple spaces. When it is necessary to close the space above a certain partition mechanism 4 so that the top space does not need cold air, rotate the rotating knob 47 to drive the second inclined groove semi-circular block 46. The inclined surface of the second inclined groove semi-circular block 46 abuts against the inclined surface of the first inclined groove semi-circular block 45, so that the first inclined groove semi-circular block 45 drives the sealing plate 44 to be squeezed downward, so that the sealing plate 44 abuts against and seals the through groove at the bottom of the hollow through plate 41, preventing the cold air at the bottom from being blown upward and blocking the upward path of the bottom cold air, so as to achieve the purpose of only cooling a specific lower space. Compared with the ordinary continuous refrigeration method, this structure can "actively isolate" the upper space from the cooling system when there are no items or cooling is not required in the upper space, prevent the ineffective rise of cold air, avoid cold energy loss and excessive operation of the compressor, thus significantly reducing energy consumption and improving the refrigeration efficiency and economy of the whole machine. The multiple sets of partition mechanisms 4 and the rotating knobs 47 cooperate to form a user-customizable cold air channel management system, which can determine whether a certain layer is cooled according to specific usage requirements, meet the diverse scenario requirements of different times and different item storages, and enhance the adaptability of the device in the medical environment.

[0023] The circulation mechanism 5 includes a hollow heat-insulating frame 55. A top input port 56 is fixedly connected to the top of the hollow heat-insulating frame 55. A bottom return port 57 is fixedly connected to the bottom of the hollow heat-insulating frame 55. The bottom return port 57 is fixedly connected to the inner wall of the hollow baffle 33. The fan 37 blows the air inside the hollow baffle 33 upward, and then it enters the hollow heat-insulating frame 55 through the top input port 56, and is discharged to the hollow baffle 33 again through the bottom return port 57, so that the cold air blown by the fan 37 forms a complete circulating flow path. After the cold air is sent upward, it is guided back again, avoiding direct diffusion or retention, and improving the recycling efficiency of the cold air. A hollow connecting block 51 is fixedly connected to the bottom of the hollow through plate 41. A second spring 52 is arranged on the inner wall of the hollow connecting block 51. One end of the second spring 52 is fixedly connected to the inner wall of the hollow connecting block 51, and the other end of the second spring 52 is fixedly connected to a sealing block 53. The sealing block 53 is piston-connected to the inner wall of the hollow connecting block 51. An inlet 54 is opened on the outer wall of the hollow connecting block 51. The sealing block 53 is fixedly connected to the outer wall of the connecting rod 48. The outer wall of the hollow connecting block 51 is fixedly connected to the inner wall of the hollow heat-insulating frame 55. When the sealing plate 44 moves downward for sealing, the sealing plate 44 drives the connecting disc 43 and the connecting rod 48 to move downward. The connecting rod 48 drives the sealing block 53 to move downward, so that the inlet 54 is opened, and the cold air blocked by the sealing plate 44 can be input into the hollow heat-insulating frame 55 through the hollow connecting block 51 and then form a cycle through the bottom return port 57, so that the cold air in the enclosed area can turn into the hollow heat-insulating frame 55 through the hollow connecting block 51 for reflux circulation, thus avoiding the retention or waste of cold air after being cut off, and improving the cold air utilization rate of the system. After the cold air is enclosed at a certain layer, it is not blocked and terminated, but is re-introduced into the circulation path through the hollow connecting block 51, forming a "bypass channel", effectively realizing the recycling of cold air, reducing the overall energy consumption, making the cold air resources more flexibly and efficiently distributed among different layers. The second spring 52 provides an upward elastic force. After the sealing state is cancelled, it can automatically push the sealing block 53 to reset and close the inlet 54 again. There are two hollow heat-insulating frames 55, and the two hollow heat-insulating frames 55 are symmetrically arranged. The symmetrical hollow heat-insulating frames 55 can be responsible for the cold air diversion and reflux on both sides respectively, avoiding the phenomenon of heavy cold air on one side and insufficient cooling on the other side, realizing a more balanced temperature field distribution, and ensuring the temperature consistency of the instrument storage environment.

[0024] In summary, for this energy-saving and efficient medical low-temperature instrument refrigeration device, the user opens the door 2 arranged on the front of the housing 1, places the medical instruments to be refrigerated on the specified compartment mechanism 4, selects a suitable compartment space according to the volume, category and storage requirements of the instruments. After placing, close the door 2. The sealing strip structure on the door 2 ensures that the device is in a sealed state to prevent cold air from leaking.

[0025] The user can set the required target temperature through the controller 322. The temperature sensor 323 monitors the temperature change inside the hollow baffle 33 in real time and feeds the data back to the controller 322. The controller 322 automatically controls the start and stop of the compressor body 321 according to the temperature feedback, so that the refrigeration mechanism 3 enters the working state. The compressor device 32 drives the refrigerant to perform a phase change cycle between the evaporator 35 and the radiator 36 to generate cold air. The cold air is sent upward along the inner wall of the hollow baffle 33 by the fan 37 and transmitted to the spaces where the respective partition mechanisms 4 are located. At the same time, it enters the hollow heat preservation frame 55 through the top input port 56 and then reflows back to the hollow baffle 33 through the bottom return port 57, forming a complete cold air circulation path. The evaporator 35 is fixedly arranged on the inner wall of the hollow baffle 33. The hollow baffle 33 constructs an independent cooling channel, and an insulating layer 34 is provided on its inner wall to isolate the hot air flow from the cold air flow, improve the concentration of cold quantity and reduce thermal interference.

[0026] When the user hopes to cut off the cold for the area above a certain partition, the rotation knob 47 can be rotated to make the semi-circular inclined groove block two 46 cooperate with the inclined surface of the semi-circular inclined groove block one 45, driving the sealing plate 44 to move downward to close the bottom through groove of the hollow through plate 41 and block the upward path of the cold air. Compared with the ordinary continuous refrigeration method, this structure can "actively isolate" the upper space from the cooling system when there are no items or no cooling is required in the upper space, prevent the ineffective rise of cold air, avoid cold quantity loss and excessive operation of the compressor, thereby significantly reducing energy consumption and improving the refrigeration efficiency and economy of the whole machine. The multiple partition mechanisms 4 cooperate with the rotation knob 47 to form a cold air channel management system that can be customized by the user, and it can be determined whether a certain layer is supplied with cold according to specific usage requirements, meeting the diverse scenario requirements of different times and different item storage, and enhancing the adaptability of the device in the medical environment.

[0027] When the sealing plate 44 moves downward, the sealing plate 44 drives the connecting disc 43 and the connecting rod 48 to move downward. The connecting rod 48 drives the sealing block 53 downward to open the inlet 54, so that the intercepted cold air is introduced into the hollow heat preservation frame 55 through the hollow connecting block 51 for recycling, enabling the cold air in the enclosed area to enter the hollow heat preservation frame 55 through the hollow connecting block 51 for reflux circulation, thereby avoiding the retention or waste of cold air after being intercepted, improving the cold air utilization rate of the system. After the cold air is enclosed in a certain layer, it is not blocked and terminated, but is re-introduced into the circulation path through the hollow connecting block 51 to form a "bypass channel", effectively realizing the recycling of cold air, reducing the overall energy consumption, and making the cold air resources more flexibly and efficiently distributed among different layers.
