Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration devices, and in particular to an energy-saving and high-efficiency refrigeration device for medical low-temperature equipment. Background Art

[0002] A medical cryogenic device refrigeration unit is a device specifically designed to store or process medical devices in a low-temperature environment. It is intended to inhibit bacterial growth, prolong the sterility of the device, or assist in specific medical technologies by controlling the temperature.

[0003] Existing medical cryogenic equipment refrigeration systems generally employ a system-wide cooling approach during operation. This involves a compressor and evaporator working together to continuously cool the entire internal cavity after startup to maintain a set temperature. This design can meet operational requirements when large quantities of instruments or samples need to be cooled. However, in practice, medical scenarios present significant operational flexibility and the random nature of instrument usage. During certain periods, only a small number of instruments or single containers need to be cooled. In these situations, the system still needs to cool the entire internal space, causing the system to maintain an unnecessary low temperature for extended periods. This leads to continuous power consumption and frequent operation of system components, significantly reducing energy efficiency and increasing mechanical wear and maintenance of refrigeration components. From an energy conservation perspective, when the target volume is significantly smaller than the refrigeration space, the majority of the cooling capacity required to maintain the low temperature is used to cool the air within the cavity and unused areas. This heat exchange process is not only inefficient but also leads to irrational energy allocation. Therefore, existing medical cryogenic equipment refrigeration systems suffer from significant energy waste when responding to small cooling needs. The inability to flexibly adjust the cooling range and operating state based on the number of cooling targets limits further optimization potential for energy conservation and efficient use of this type of equipment.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides an energy-saving and efficient medical cryogenic equipment refrigeration device with the following beneficial effects:

[0018] 1. This energy-saving and efficient medical cryogenic equipment refrigeration device utilizes an interlayer mechanism. By turning the knob, the sealing plate is driven downward to close the hollow through-groove at the bottom of the plate, thereby blocking the upward path of cold air. When there is nothing in the upper space or no cooling is required, it is "actively isolated" from the cooling system to prevent the cold air from rising ineffectively, thereby significantly reducing energy consumption and improving the refrigeration efficiency and economy of the entire machine.

[0019] 2. This energy-saving and efficient medical low-temperature equipment refrigeration device utilizes a refrigeration mechanism. Cold air is sent up along the inner wall of the hollow baffle through a fan and transmitted to the space where each compartment mechanism is located. At the same time, it enters the hollow insulation frame through the top input port and then flows back to the hollow baffle through the bottom return port, forming a complete cold air circulation path.

[0020] 3. This energy-saving and efficient medical low-temperature equipment refrigeration device utilizes a circulation mechanism. When the sealing plate moves downward, the cut-off cold air is introduced into the hollow insulation frame through the hollow connecting block for recycling, so that the cold air in the enclosed area can be turned into the hollow insulation frame through the hollow connecting block for reflux circulation, thereby avoiding the retention or waste of cold air after being cut off, and improving the utilization rate of the system cold air. After the cold air is sealed at a certain layer, it is not blocked and terminated, but is re-introduced into the circulation path through the hollow connecting block, forming a "bypass channel", effectively realizing the recycling and reuse of cold air, reducing overall energy consumption, and making cold air resources more flexible and efficient distribution among different floors.

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.

[0031] See also Figures 1-8, an energy-saving and efficient medical low-temperature equipment refrigeration device, comprising: a shell 1, which is used to constitute the external structural frame of the entire refrigeration device, forming a closed 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, which is arranged on the front of the shell 1.

[0032] The refrigeration mechanism 3 includes a heat dissipation hole 31 and a connecting pipe 38. The heat dissipation hole 31 is set on the outer wall of the shell 1 to realize the timely discharge of the heat generated inside and avoid the temperature rise of the equipment affecting the refrigeration efficiency. The inner wall of the shell 1 is fixedly connected to a compressor device 32 for compressing and transporting the refrigerant. It is the power core of the entire refrigeration cycle system. A hollow baffle 33 is set on the inner wall of the shell 1. An insulating layer 34 is opened 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 shell 1. A fan 37 is set on the inner wall of the hollow baffle 33 for driving The cold air circulates along the channel, allowing the cold air to be quickly distributed to various areas 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 connected to the evaporator 35 at the same time to form a complete closed refrigeration circuit, and forms a condensation path with the radiator 36 through the connecting pipe 38, constructing a standard refrigeration cycle process from compression, condensation, throttling to evaporation, and transporting the high-temperature and high-pressure gaseous refrigerant to the radiator 36 for heat exchange and condensation into liquid. The liquid refrigerant then enters the evaporator 35 through the connecting pipe 38, absorbs heat in the evaporator 35 and evaporates quickly to achieve a 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.

There are two groups of heat dissipation holes 31, and the two groups of heat dissipation holes 31 are symmetrically arranged on the shell 1. By arranging two groups of symmetrical heat dissipation holes 31 on the shell 1, it is possible to ensure that heat is discharged evenly on both sides of the inner wall of the shell 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, thereby affecting the normal operation of the equipment. The symmetrically arranged heat dissipation holes 31 contribute to the balance of air flow and convection process. By evenly dissipating heat, the fluidity and heat dissipation effect of the external air are improved, which helps to accelerate the balanced distribution of internal temperature, prevent the accumulation of condensed water or moisture, and thus improve the stability and service life of the device.

[0033] The interlayer mechanism 4 includes a hollow through plate 41, which is fixedly connected to the inner wall of the shell 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 spring 42 is provided on the inner wall of the hollow through plate 41. One end of the spring 42 is fixedly connected to the inner wall of the hollow through plate 41, and the other end of the spring 42 is fixedly connected to a connecting disc 43. The outer wall of the connecting disc 43 is fixedly connected to a sealing plate 44. A connecting rod 48 is fixedly connected to the inner wall of the connecting disc 43. The outer wall of the connecting rod 48 is slidably connected to the inner wall of the hollow through plate 41. When the fan 37 at the bottom blows the cold air upward After the movement, it will pass through the upper and lower through grooves of the hollow through plate 41, and impact the sealing plate 44 in the hollow through plate 41, so that the cold air bypasses the sealing plate 44 and is discharged through the through groove on the top of the hollow through plate 41. This design can effectively delay the upward speed of the cold air, making the internal air flow slow, avoiding the internal space being blown by the cold air at too fast a speed, avoiding the rapid impact of the cold air causing disturbance of the internal space, and reducing the possibility of strong cold wind directly impacting the storage area. The top of the sealing plate 44 is fixedly connected to the inclined groove semicircular block 1 45, and the inner wall of the hollow through plate 41 is rotatably connected to the inclined groove semicircular block 2 46. The top of the second circular block 46 is fixedly connected with a rotating button 47. The interlayer mechanism 4 is provided with multiple groups. The multiple interlayer mechanisms 4 divide the space in the shell 1 into multiple spaces. When it is necessary to seal the space above a certain layer of the interlayer mechanism 4 so that the top space does not need to be cooled, the rotating button 47 is turned to drive the second inclined groove semicircular block 46. The inclined surface of the second inclined groove semicircular block 46 collides with the inclined surface of the first inclined groove semicircular block 45, so that the first inclined groove semicircular block 45 drives the sealing plate 44 to be squeezed downward, so that the sealing plate 44 and the through groove at the bottom of the hollow through plate 41 are in conflict and sealed, thereby preventing the cold air at the bottom from being blown upward and blocking the rising path of the cold air at the bottom. path, thereby achieving the purpose of fixed-point cooling of the lower space only. Compared with the ordinary continuous refrigeration method, this structure can "actively isolate" the upper space from the cooling system when there is no object or no cooling is required, preventing the cold air from rising ineffectively, avoiding cooling 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 groups of interlayer mechanisms 4 and the rotating knob 47 cooperate to form a user-customizable cold air channel management system, which can determine whether a certain layer should be cooled according to specific usage needs, meet the diverse scene requirements of different times and different storage of items, and enhance the adaptability of the device in medical environments.

[0034] The circulation mechanism 5 includes a hollow insulation frame 55, the top of the hollow insulation frame 55 is fixedly connected to a top input port 56, the bottom of the hollow insulation frame 55 is fixedly connected to a bottom return port 57, and the bottom return port 57 is fixedly connected to the inner wall of the hollow baffle 33. The fan 37 blows the air in the hollow baffle 33 upward, and then enters the hollow insulation frame 55 through the top input port 56, and then is discharged to the hollow baffle 33 through the bottom return port 57, so that the cold air blown out by the fan 37 forms a complete circulation flow path. After being sent up, the cold air is guided back to the air again to avoid direct diffusion or retention, thereby improving the circulation of the cold air. In order to improve the utilization efficiency, the bottom of the hollow through plate 41 is fixedly connected with a hollow connecting block 51, and a spring 2 52 is provided on the inner wall of the hollow connecting block 51. One end of the spring 2 52 is fixedly connected to the inner wall of the hollow connecting block 51, and the other end of the spring 2 52 is fixedly connected to a sealing block 53. The sealing block 53 is connected to the inner wall piston of the hollow connecting block 51. An inlet 54 is provided on the outer wall of the hollow connecting block 51, and the outer wall of the connecting rod 48 is fixedly connected with the sealing block 53. The outer wall of the hollow connecting block 51 is fixedly connected to the inner wall of the hollow insulation frame 55. When the sealing plate 44 moves downward for sealing, the sealing plate 44 is provided with The movable connecting disc 43 and the connecting rod 48 move downward, and the connecting rod 48 drives the sealing block 53 to move downward, so that the inlet 54 is opened, so that the cold air blocked by the sealing plate 44 can be input into the hollow insulation frame 55 through the hollow connecting block 51, and then circulate through the bottom return port 57, so that the cold air in the enclosed area can be turned into the hollow insulation frame 55 through the hollow connecting block 51 for reflux circulation, thereby avoiding the retention or waste of the cold air after being cut off, and improving the utilization rate of the system cold air. After the cold air is sealed at a certain layer, it is not blocked and terminated, but is re-introduced through the hollow connecting block 51 The circulation path forms a "bypass channel", which effectively realizes the recycling and reuse of cold air, reduces overall energy consumption, and makes the cold air resources more flexible and efficient in distribution among different layers. Spring 2 52 provides an upward elastic force, which can automatically push the sealing block 53 to reset after the sealing state is cancelled, and reclose the entrance 54. There are two hollow insulation frames 55, and the two hollow insulation frames 55 are symmetrically arranged. The symmetrical hollow insulation frames 55 can be responsible for the cold air diversion and reflux on both sides respectively, avoiding the phenomenon that the cold air is heavy on one side and the other side is insufficiently cooled, achieving a more balanced temperature field distribution, and ensuring the temperature consistency of the equipment storage environment.

[0035] To sum up, in this energy-saving and efficient medical low-temperature equipment refrigeration device, the user opens the door 2 set on the front of the shell 1, places the medical equipment to be refrigerated on the designated compartment mechanism 4, selects the appropriate compartment space according to the volume, category, and storage requirements of the equipment, and closes the door 2 after placement. The sealing strip structure on the door 2 ensures that the device is in a sealed state to prevent cold air from leaking.

[0036] The user can set the desired target temperature through controller 322. Temperature sensor 323 monitors temperature changes within hollow baffle 33 in real time and feeds data back to controller 322. Controller 322 automatically controls the start and stop of compressor 321 based on the temperature feedback, putting refrigeration mechanism 3 into operation. Compressor 32 drives the refrigerant through a phase change cycle between evaporator 35 and radiator 36, generating cold air. Fan 37 then transports the cold air up the inner wall of hollow baffle 33 and into the spaces where each interlayer mechanism 4 is located. It then enters hollow insulation frame 55 through top inlet 56 and flows back into hollow baffle 33 through bottom return port 57, completing the cold air circulation path. Evaporator 35 is fixed to the inner wall of hollow baffle 33, creating an independent cooling channel. An insulating layer 34 is provided on its inner wall to isolate the hot and cold air flows, improving cooling concentration and reducing thermal interference.

[0037] When the user wishes to cut off the cooling of the area above a certain compartment, the user can turn the rotary knob 47 to make the inclined groove semicircular block 2 46 cooperate with the inclined surface of the inclined groove semicircular block 1 45, driving the sealing plate 44 to close the hollow bottom groove of the plate 41 downward, blocking the upward path of cold air. Compared with the ordinary continuous refrigeration method, this structure can "actively isolate" the upper space from the cooling system when there is no object or no cooling is required, preventing the cold air from rising ineffectively, avoiding cold loss and excessive operation of the compressor, thereby significantly reducing energy consumption and improving the cooling efficiency and economy of the entire machine. Multiple groups of compartment mechanisms 4 cooperate with the rotary knob 47 to form a user-customizable cold air channel management system, which can determine whether a certain layer should be cooled according to specific usage needs, meet the diverse scene requirements of different times and different item storage, and enhance the adaptability of the device in medical environments.

[0038] When the sealing plate 44 moves downward, the sealing plate 44 drives the connecting disc 43 and the connecting rod 48 to move downward, and the connecting rod 48 drives the sealing block 53 downward to open the inlet 54, so that the cut-off cold air is introduced into the hollow insulation frame 55 through the hollow connecting block 51 for recycling, so that the cold air in the enclosed area can be turned into the hollow insulation frame 55 through the hollow connecting block 51 for reflux circulation, thereby avoiding the retention or waste of cold air after being cut off, and improving the utilization rate of the system cold air. After the cold air is sealed 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", which effectively realizes the recycling and reuse of cold air, reduces overall energy consumption, and makes the cold air resources more flexible and efficient in distribution among different layers.
