DETAILED DESCRIPTION

[0024] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] like Figures 1 to 5 As shown, an embodiment of the present invention provides a programmed cooling device, comprising: A refrigeration assembly, the refrigeration assembly includes a compressor 100, a condenser 102, a condenser separator 104, an intermediate heat regenerator 106, a first throttling element 108 and an evaporator 110 which are fluidly connected; A cooling assembly, the cooling assembly includes a cooling tank 112, a first heating element 114, a pump body 116 and a sample chamber 118 which are fluid-connected. The sample chamber 118 is used to place the sample to be tested and a sample partition and a second heating element 120 are arranged in the sample chamber 118; The cooling liquid in the cooling tank 112 is used to exchange heat with the evaporator 110 to cool the sample chamber 118 .

[0026] According to the program cooling instrument provided by the embodiment of the present invention, the refrigeration component adopts a closed loop design, combined with high-efficiency components such as the condensation separator 104 and the intermediate heat exchanger 106, which greatly improves the refrigeration efficiency and stability. The cooling component drives the cooling liquid circulation through the pump body 116, accurately transfers the cold generated by the refrigeration component to the sample chamber 118, and combines the adjustment of the first heating element 114 and the second heating element 120 to achieve accurate control of the temperature in the sample chamber 118. The sample partition in the sample chamber 118 can be separated and adjusted according to actual needs to meet the cooling requirements of samples of different shapes and quantities. At the same time, by adjusting the working state of the first heating element 114 and the second heating element 120, a complex temperature control strategy can be implemented to meet the diverse experimental and application requirements. The entire system adopts advanced control and protection mechanisms to ensure that the sample or equipment will not be damaged due to too low or too high temperature during the cooling process. More importantly, by coupling the refrigeration component with the cooling component, the use of liquid nitrogen can be omitted, and only the refrigeration component can be used as a cold source to achieve program cooling of the sample being tested.

[0027] Please continue to see Figures 1 to 5 The embodiment of the present invention provides a program cooling device, which is designed to achieve accurate and controllable cooling of samples in the sample chamber 118. The cooling device is mainly composed of two core components: a refrigeration component and a cooling component.

[0028] The refrigeration assembly is a closed refrigeration cycle system, which mainly includes the following components and is connected by pipeline fluid: Compressor 100: responsible for compressing the refrigerant, increasing its pressure and temperature, and providing power for the refrigeration cycle.

[0029] It should be noted that the refrigerant can be one or more of methane, ethane, propane, isobutane, isopentane, ethylene, nitrogen, etc.

[0030] Condenser 102: receives high-temperature and high-pressure refrigerant from compressor 100, and converts it into high-pressure liquid refrigerant by heat dissipation.

[0031] Separator 104: further separates different components in the liquid refrigerant to ensure the stability and efficiency of the refrigeration process.

[0032] Intermediate heat regenerator 106: utilizes the temperature difference of refrigerants in different states in the refrigeration cycle to perform heat exchange and improve the overall refrigeration efficiency.

[0033] The first throttling element 108 reduces the pressure and temperature of the liquid refrigerant through throttling so that the liquid refrigerant reaches a suitable state before entering the evaporator 110 .

[0034] Evaporator 110: evaporates the refrigerant at low pressure and low temperature, absorbs the heat in the cooling liquid, and achieves a cooling effect. The temperature of the evaporator 110 can drop to as low as -190 degrees Celsius.

[0035] The cooling component is responsible for transferring the cooling energy generated by the refrigeration component to the sample chamber 118, and mainly includes: The cooling tank 112 stores cooling liquid, which is connected to the evaporator 110 through a pipeline and absorbs cold energy through heat exchange.

[0036] It should be noted that the cooling liquid can be one or more isomers of anhydrous ethanol, propanol, butanol, pentane, hexane, and hexene.

[0037] The first heating element 114 is used to preheat or adjust the temperature of the cooling liquid in the cooling tank 112 when necessary to meet different cooling requirements.

[0038] Pump body 116: drives the cooling liquid to circulate between the cooling tank 112 and the sample chamber 118 to ensure effective transfer of cooling capacity.

[0039] Sample chamber 118: used to place the sample to be tested, with a sample partition inside, which can separate different samples or adjust the cooling area as needed. At the same time, the second heating element 120 can heat the sample chamber 118 when necessary to achieve a more complex temperature control strategy.

[0040] It should be noted that the temperature of the sample partition can drop to as low as -130 degrees Celsius, and the maximum cooling rate can exceed 30 Kelvin / minute.

[0041] According to one embodiment of the present invention, the refrigeration assembly further includes an oil separator 122, a dryer 124 and a low-temperature stage reheater 126, the oil separator 122 is fluidically connected to the downstream of the compressor 100, the dryer 124 is fluidically connected to the downstream of the oil separator 122, the low-temperature stage reheater 126 is fluidically connected to the intermediate-stage reheater, and the first throttling element 108 is connected between the intermediate-stage reheater and the low-temperature stage reheater 126.

[0042] In the embodiment of the present invention, an oil separator 122, a dryer 124 and a low-temperature heat recovery pipe are added on the basis of the original refrigeration assembly.

[0043] The oil separator 122 is fluidically connected to the downstream of the compressor 100. The oil separator 122 is used to separate the lubricating oil from the refrigerant hot gas discharged by the compressor 100 to prevent the lubricating oil from entering other parts of the refrigeration system and affecting the refrigeration effect and the stable operation of the equipment. The separated lubricating oil is returned to the oil sump of the compressor 100 through the built-in control device to ensure the lubrication and cooling of the compressor 100.

[0044] The dryer 124 is fluidically connected to the downstream of the oil separator 122. The dryer 124 is used to absorb moisture and impurities in the refrigerant and air to prevent these harmful substances from entering the refrigeration system and causing corrosion, blockage and other faults. The desiccant (such as copper hydroxide, silica gel, etc.) in the dryer 124 can absorb these harmful substances and improve the efficiency and life of the refrigeration system.

[0045] After the low-temperature regenerator 126 is fluidically connected to the intermediate-stage regenerator, the first throttling member 108 is connected between the intermediate-stage regenerator and the low-temperature regenerator 126. The low-temperature regenerator 126 is used to further recover and utilize the heat in the refrigeration cycle to improve the refrigeration efficiency. In the low-temperature regenerator 126, the high-temperature and high-pressure refrigerant vapor exchanges heat with the low-temperature and low-pressure refrigerant liquid, so that the temperature of the refrigerant vapor is reduced and the temperature of the refrigerant liquid is increased, which helps the refrigerant to better absorb heat in the evaporator 110.

[0046] The oil separator 122 ensures the stable operation of the compressor 100 and reduces the energy loss caused by the mixing of lubricating oil into the refrigerant. The dryer 124 prevents the corrosion and blockage of the refrigeration system by moisture and impurities, and improves the stability and efficiency of the system. The addition of the low-temperature regenerator 126 further improves the recovery and utilization efficiency of heat, making the entire refrigeration cycle more efficient. The use of the oil separator 122 and the dryer 124 reduces the failure points in the refrigeration system and improves the reliability and stability of the system. The low-temperature regenerator 126 helps to balance the temperature difference in the refrigeration cycle and reduces the system instability factors caused by temperature fluctuations. By accurately controlling the various components in the refrigeration assembly, the program cooling device of the present invention can adapt to the cooling requirements within different temperature ranges. The addition of the oil separator 122, the dryer 124 and the low-temperature regenerator 126 makes the program cooling device have a wider application prospect in the fields of biomedicine, materials science, food science, etc. The efficient refrigeration cycle and heat recovery mechanism reduce the waste of energy and meet the concept of energy saving and environmental protection. By accurately controlling the temperature, energy waste and environmental pollution caused by excessive cooling are avoided.

[0047] According to one embodiment of the present invention, a second throttling device 134 is further connected between the low-temperature stage regenerator 126 and the evaporator 110 .

[0048] In the embodiment of the present invention, in the original refrigeration assembly design, a second throttling member 134 is added between the low temperature stage regenerator 126 and the evaporator 110. This design is intended to further optimize the refrigeration cycle, improve refrigeration efficiency, and ensure stable operation of the system.

[0049] The second throttle 134 is installed between the outlet of the low temperature stage regenerator 126 and the inlet of the evaporator 110 to form a throttling passage. The main function of the second throttle 134 is to adjust the flow rate and pressure of the refrigerant entering the evaporator 110. Through the throttling effect, the second throttle 134 can reduce the pressure and temperature of the refrigerant, so that it is in a more suitable state when entering the evaporator 110. This helps to improve the heat exchange efficiency of the evaporator 110, thereby optimizing the performance of the entire refrigeration system.

[0050] In the refrigeration cycle, the temperature and pressure of the refrigerant have been adjusted to a certain extent after passing through the low temperature stage regenerator 126. However, in order to ensure that the refrigerant can fully evaporate and absorb heat when entering the evaporator 110, a second throttling member 134 needs to be added between the low temperature stage regenerator 126 and the evaporator 110.

[0051] The second throttling member 134 causes pressure drop and temperature drop when the refrigerant flows through the throttling member 134, which helps the refrigerant to evaporate better in the evaporator 110, thereby improving the refrigeration efficiency.

[0052] The addition of the second throttle 134 not only optimizes the refrigeration cycle, but also improves the stability of the system. By accurately controlling the flow rate and pressure of the refrigerant entering the evaporator 110, the system can avoid failures caused by too much or too little refrigerant.

[0053] At the same time, the second throttle member 134 can also play a buffering role, reducing the pressure and temperature fluctuations that may occur during the operation of the refrigeration system, which helps to protect other components in the system from damage and prolong the service life of the entire refrigeration system.

[0054] The addition of the second throttle 134 allows the refrigerant to be in a more suitable state when entering the evaporator 110, thereby improving the heat exchange efficiency of the evaporator 110. This helps to speed up the refrigeration speed and reduce energy consumption. By accurately controlling the flow rate and pressure of the refrigerant entering the evaporator 110, the second throttle 134 helps to reduce pressure and temperature fluctuations in the system. This helps to protect other components in the system from damage and improve the stability of the entire refrigeration system. As an important component in the refrigeration cycle, the addition of the second throttle 134 makes the refrigeration cycle more complete and optimized. This helps to improve the performance and efficiency of the entire refrigeration system and meet the refrigeration needs in different application scenarios.

[0055] According to one embodiment of the present invention, the refrigeration assembly further includes a working fluid storage tank 128, which is fluidically connected between the compressor 100 and the second throttling member 134, and is used to adjust the quality of the working fluid in the refrigeration assembly.

[0056] In the embodiment of the present invention, a working fluid storage tank 128 is also introduced into the refrigeration assembly. The position of the working fluid storage tank 128 in the refrigeration cycle is crucial, and it is arranged in fluid communication between the output end of the compressor 100 and the second throttling member 134. The "fluid communication" here means that the working fluid (i.e., the refrigerant) can flow through the working fluid storage tank 128 after being compressed by the compressor 100 and before entering the second throttling member 134 for throttling.

[0057] The main function of the working fluid storage tank 128 is to adjust the quality of the working fluid in the refrigeration assembly. During the operation of the refrigeration system, the demand for working fluid in the refrigeration system may change due to various factors (such as load changes, ambient temperature fluctuations, etc.). The working fluid storage tank 128 can store or release working fluid as needed to maintain the appropriate amount of working fluid in the system. This dynamic adjustment helps to ensure that the refrigeration system can maintain efficient and stable operation under various operating conditions.

[0058] Through the dynamic adjustment of the working fluid by the working fluid storage tank 128, the refrigeration system can better cope with changes in load and environmental conditions, thereby improving the overall stability of the system. The right amount of working fluid is the key to the efficient operation of the refrigeration system. The working fluid storage tank 128 ensures that the right amount of working fluid is always maintained in the system, avoiding the loss of energy efficiency due to too much or too little working fluid. Under different working conditions, the refrigeration system has different requirements for working fluid. The introduction of the working fluid storage tank 128 enables the refrigeration system to better adapt to these changes, improving the flexibility and adaptability of the system. The right amount of working fluid helps to reduce the wear and load of the compressor 100 and other refrigeration components, thereby extending the service life of the entire refrigeration system. Because the working fluid storage tank 128 can automatically adjust the quality of the working fluid, the need for manual intervention is reduced, thereby simplifying the maintenance of the refrigeration system.

[0059] According to an embodiment of the present invention, a first circuit is connected between the condensation separator 104 and the compressor 100 , and at least one of a temperature detection element 130 and a pressure detection element 132 is disposed on the first circuit.

[0060] In the embodiment of the present invention, based on the original refrigeration assembly, this embodiment adds a first circuit connected between the condenser 104 and the compressor 100, and a temperature detection element 130 and / or a pressure detection element 132 are arranged on the circuit.

[0061] The first loop is connected between the outlet of the condenser 104 and the inlet of the compressor 100, forming a closed loop or bypass system. The first loop allows part of the refrigerant fluid to circulate between the condenser 104 and the compressor 100 to adjust and stabilize the state (such as temperature and pressure) of the refrigerant entering the compressor 100. This helps to protect the compressor 100 from excessively high or low temperature and pressure shocks and extend its service life.

[0062] The temperature detection element 130 is installed on the first circuit and is used to monitor the temperature of the refrigerant in the circuit in real time. The temperature detection element 130 can accurately measure the temperature of the refrigerant in the first circuit and transmit the data to the control system. The control system can adjust the operating parameters of the refrigeration system according to the temperature data to ensure that the refrigerant reaches a suitable temperature range before entering the compressor 100.

[0063] The pressure detection element 132 is also installed on the first circuit to monitor the pressure of the refrigerant in the circuit in real time. The pressure detection element 132 can accurately measure the pressure of the refrigerant in the first circuit and feed the data back to the control system. The control system can adjust the operating state of the compressor 100 or adjust other components according to the pressure data to maintain the pressure stability in the refrigeration system.

[0064] By arranging the temperature detection member 130 and the pressure detection member 132 on the first loop, the state of the refrigerant can be monitored in real time, and abnormal conditions can be discovered and handled in time. This helps to avoid the refrigeration system from shutting down due to faults such as overheating and overpressure, and improves the stability and reliability of the system. The introduction of the first loop allows the refrigerant to be preheated or depressurized before entering the compressor 100, thereby preventing the compressor 100 from being damaged by directly being subjected to excessively high or low temperatures and pressures. This helps to extend the service life of the compressor 100 and reduce maintenance costs. By accurately controlling the temperature and pressure of the refrigerant in the first loop, it can be ensured that the refrigerant is in the best state before entering the evaporator 110. This helps to improve the heat exchange efficiency of the evaporator 110, thereby optimizing the refrigeration efficiency of the entire refrigeration system. The data of the temperature detection member 130 and the pressure detection member 132 can be transmitted to the control system to realize intelligent monitoring and management of the refrigeration system. The control system can automatically adjust the operating parameters of the system according to the real-time monitoring data to improve the automation and operating efficiency of the system.

[0065] In addition, it should be noted that the temperature detection component 130 and the pressure detection component 132 may not be limited to the first circuit, but may also be set at other locations where temperature and pressure measurement are required, which will not be described in detail here.

[0066] According to one embodiment of the present invention, the oil separator 122 is fluidly connected to the first circuit.

[0067] In the embodiment of the present invention, in the original refrigeration component design, the oil separator 122 is further introduced into the fluid communication with the first circuit. This design not only optimizes the overall structure of the refrigeration system, but also significantly improves the performance and stability of the system.

[0068] The oil separator 122 is designed to be fluidically connected between the downstream of the compressor 100 and the first circuit. Specifically, the outlet of the oil separator 122 can be connected to a node of the first circuit, so that the refrigerant hot gas containing lubricating oil discharged from the compressor 100 can first enter the oil separator 122 for oil-gas separation, and then adjust the temperature and pressure through the first circuit.

[0069] In the oil separator 122, the lubricating oil in the hot gas of the refrigerant is effectively separated and returned to the oil sump of the compressor 100 through the control device provided therewith. The refrigerant after the oil and gas separation continues to flow to the first circuit for subsequent temperature and pressure adjustment.

[0070] Due to the addition of the oil separator 122, the first circuit not only plays a role in regulating the temperature and pressure of the refrigerant, but also assumes the function of separating the oil and gas in the refrigerant, which further improves the overall performance and stability of the refrigeration system.

[0071] At the same time, the temperature detection element 130 and the pressure detection element 132 on the first circuit can still monitor the state of the refrigerant in real time to ensure that the refrigerant is in the best state before entering the evaporator 110 .

[0072] The connection of the oil separator 122 to the first circuit enables the refrigerant to undergo more complete oil-gas separation and temperature and pressure regulation before entering the evaporator 110. This helps to avoid excessive lubricating oil from being mixed into the refrigerant, which affects the heat exchange efficiency of the evaporator 110. At the same time, it can also effectively prevent system failures caused by unstable refrigerant temperature and pressure. The effective separation and recovery of lubricating oil by the oil separator 122 reduces the circulation amount of lubricating oil in the refrigeration system. This helps to reduce the operating load and wear of the compressor 100, thereby extending the service life of the compressor 100. The refrigerant after oil-gas separation and temperature and pressure regulation is purer and more stable when entering the evaporator 110. This helps to improve the heat exchange efficiency of the evaporator 110, thereby optimizing the refrigeration efficiency of the entire refrigeration system. The connection of the oil separator 122 to the first circuit makes the maintenance of the refrigeration system easier. Maintenance personnel can promptly detect and handle abnormal conditions by monitoring the temperature detection element 130 and the pressure detection element 132 on the first circuit. At the same time, since the lubricating oil is effectively separated and recovered, the system maintenance cost caused by lubricating oil pollution is also reduced.

[0073] According to one embodiment of the present invention, the cooling assembly further includes a coolant storage tank 136, which is connected between the first heating element 114 and the sample chamber 118, and is used to replenish the coolant in the cooling assembly.

[0074] In the embodiment of the present invention, a key component, a coolant storage tank 136, is introduced into the original design of the cooling component, and is connected between the first heating element 114 and the sample chamber 118. This design is intended to ensure that the cooling component can continuously and stably provide an appropriate amount of coolant to the sample chamber 118 during operation to meet the cooling requirements in different application scenarios.

[0075] The coolant storage tank 136 is installed on the pipeline between the first heating element 114 and the sample chamber 118 to form an independent coolant circulation system. The main function of the coolant storage tank 136 is to store and replenish the coolant in the coolant assembly. When the coolant in the coolant assembly is reduced due to evaporation, leakage or other reasons, the coolant storage tank 136 can replenish new coolant to the system in time to ensure the continuous operation and cooling effect of the system.

[0076] During the operation of the cooling assembly, the coolant absorbs heat in the sample chamber 118, is heated by the first heating element 114 (in some cases, it may be to adjust the temperature or state of the coolant), and then flows back to the coolant storage tank 136 for storage or recycling. When the system detects that the coolant is insufficient (for example, by monitoring the liquid level of the coolant storage tank 136 or the cooling effect of the system), the control system will trigger a signal to make the coolant flow out of the storage tank and replenish the coolant assembly through the pipeline.

[0077] The introduction of the coolant storage tank 136 enhances the stability and reliability of the coolant assembly. By continuously and stably adding coolant to the system, the coolant assembly can maintain an efficient cooling effect and avoid system failures caused by insufficient coolant. At the same time, the coolant storage tank 136 also acts as a buffer to cope with possible coolant fluctuations or leaks in the system and ensure the continuous operation of the system.

[0078] The addition of the refrigerant storage tank 136 enables the cooling component to continuously and stably provide an appropriate amount of refrigerant to the sample chamber 118. This helps to maintain a stable temperature in the sample chamber 118 and improve the cooling efficiency. By continuously replenishing the refrigerant, the refrigerant storage tank 136 helps to reduce the possibility of refrigerant shortage or leakage in the system. This enhances the stability and reliability of the system and reduces the risk of system failure. The introduction of the refrigerant storage tank 136 makes the management of the refrigerant simpler and more efficient. Maintenance personnel can monitor the liquid level of the tank to keep abreast of the consumption of the refrigerant and make corresponding replenishments or replacements. The design of the cooling component is highly flexible and adaptable. By adjusting the capacity and replenishment rate of the refrigerant storage tank 136, the cooling needs in different application scenarios can be met.

[0079] According to one embodiment of the present invention, a rack 138 is further included, a refrigeration assembly and a cooling assembly are arranged on the rack 138 , and a cooling agent storage tank 136 is arranged on the top of the rack 138 .

[0080] In the embodiment of the present invention, based on the original design, a key component, the rack 138, is introduced, and key components such as the refrigeration component, the cooling component, and the cooling agent storage tank 136 are reasonably arranged on the rack 138. In particular, the cooling agent storage tank 136 is arranged on the top of the rack 138. This layout design is intended to optimize the system structure, improve space utilization, and enhance the stability and reliability of the system.

[0081] The rack 138 is made of strong and durable materials, and has sufficient strength and stability to support and fix key components such as the refrigeration assembly, the cold carrier assembly, and the coolant storage tank 136. The rack 138 not only plays a supporting and fixing role, but also optimizes the space utilization inside the system through a reasonable layout design, making the connection between various components more compact and efficient. At the same time, the rack 138 also provides a convenient maintenance and operation space, which is convenient for maintenance personnel to perform daily maintenance and troubleshooting.

[0082] The coolant storage tank 136 is arranged on the top of the rack 138. This layout design helps to reduce the flow resistance of the coolant in the system, improve the cooling efficiency of the system, and facilitate the coolant to replenish the coolant to the coolant assembly through the action of gravity. At the same time, placing the storage tank on the top can also facilitate maintenance personnel to observe and monitor the liquid level of the storage tank, and replenish or replace the coolant in time. Although placing the coolant storage tank 136 on the top of the rack 138 may increase the load of the rack 138, through reasonable structural design and material selection, it is ensured that the rack 138 has sufficient strength and stability to safely support the weight of the storage tank and the coolant inside it.

[0083] The introduction of the rack 138 enables the various components in the system to be arranged compactly together, reducing space waste. At the same time, placing the coolant storage tank 136 on the top of the rack 138 can further save space, making the entire system more compact and efficient. The rack 138 is made of sturdy and durable materials and has sufficient strength and stability. Through reasonable structural design, it is ensured that the rack 138 can safely support and fix the various components in the system, thereby improving the overall stability of the system. Placing the coolant storage tank 136 on the top of the rack 138 helps to reduce the flow resistance of the coolant in the system and improve the cooling efficiency of the system. At the same time, a reasonable layout design can also reduce energy loss and interference factors in the heat transfer process, allowing the system to operate more efficiently. The design of the rack 138 makes it easy to disassemble and replace the various components in the system, making it convenient for maintenance personnel to perform daily maintenance and troubleshooting. In addition, the rack 138 also reserves enough space to add new components or functions when needed in the future, thereby improving the scalability of the system.

[0084] According to one embodiment of the present invention, the sample chamber 118 is provided with a door body 140 , and a lock body 142 is provided on the door body 140 .

[0085] In the embodiment of the present invention, based on the original design of the sample chamber 118, the key components of the door body 140 and the lock body 142 are introduced to improve the sealing and safety of the sample chamber 118 and ensure the stability and integrity of the sample during the cooling process.

[0086] The door body 140 is a sealing component of the sample chamber 118, and is made of a strong and durable material with sufficient strength and sealing. The shape and size of the door body 140 match the opening of the sample chamber 118, and can fit tightly at the opening of the sample chamber 118 to form an effective seal. The main function of the door body 140 is to seal the sample chamber 118 to prevent outside air, moisture or other impurities from entering the sample chamber 118, affecting the cooling effect of the sample or causing contamination. At the same time, the door body 140 can also protect the sample from external impact or damage to ensure the integrity and safety of the sample.

[0087] The lock body 142 is installed on the door body 140 and is used to lock and unlock the door body 140. The lock body 142 adopts a reliable locking mechanism, which can ensure that the door body 140 remains in a stable locked state when closed, and prevent the door body 140 from accidentally opening or loosening. The main function of the lock body 142 is to provide additional security to prevent sample loss or safety accidents caused by accidental opening of the door body 140 during the cooling process. By locking the door body 140, it can be ensured that the sample is in a stable and safe environment during the cooling process to avoid external interference or damage.

[0088] The designs of the door body 140 and the lock body 142 cooperate with each other to ensure that the door body 140 can fit tightly against the opening of the sample chamber 118 when it is closed, and a stable locking state is achieved through the locking mechanism of the lock body 142. This design not only improves the sealing and safety of the sample chamber 118, but also makes the opening and closing operations of the door body 140 easier and more reliable.

[0089] The introduction of the door body 140 enables the sample compartment 118 to form an effective seal when in a closed state, preventing outside air, moisture or other impurities from entering the interior of the sample compartment 118. This helps to maintain a stable temperature inside the sample compartment 118 and reduce sample contamination or damage caused by external interference. The design of the lock body 142 provides additional security to prevent sample loss or safety accidents caused by accidental opening of the door body 140 during the cooling process. By locking the door body 140, it can be ensured that the sample is in a stable and safe environment during the cooling process to avoid external interference or damage. The design of the door body 140 and the lock body 142 makes the placement and removal of samples easier and more reliable. At the same time, the structure of the door body 140 and the lock body 142 is relatively simple, easy to maintain and replace, and reduces the maintenance cost and time of the system.

[0090] According to one embodiment of the present invention, the sample partition includes at least a first partition 144 and a second partition 146 , and at least one of the first partition 144 and the second partition 146 is adjustable in position.

[0091] In the embodiment of the present invention, the sample partition design in the sample chamber 118 has a high degree of flexibility and adjustability. Specifically, the sample partition includes at least a first partition 144 and a second partition 146, and the position of at least one of the partitions is adjustable. This design is intended to meet the storage requirements of samples of different sizes and shapes, improve space utilization, and ensure the stability and uniformity of the sample during the cooling process.

[0092] The first partition 144 serves as a basic partition unit in the sample chamber 118. The position of the first partition 144 is usually fixed, and is used to divide the sample chamber 118 into different areas for storing different types of samples.

[0093] The second partition 146 is different from the first partition 144 in that the position of the second partition 146 is adjustable, which means that the user can adjust the position of the second partition 146 according to actual needs to accommodate the storage requirements of samples of different sizes and shapes.

[0094] The second partition 146 can be designed to slide on the slide rail in the sample chamber 118, and the user can adjust its position manually or electrically. This design is simple, practical and easy to operate. Another implementation method is to adjust the height of the second partition 146 through a lifting mechanism. This design usually requires the use of a motor or a hydraulic device to drive the lifting mechanism to achieve the up and down movement of the partition. Although the structure is relatively complex, it can provide more precise position adjustment.

[0095] By adjusting the position of the partition, the user can make full use of the space in the sample chamber 118 to store more types of samples. The adjustable partition can meet the storage requirements of samples of different sizes and shapes, making the samples more stable during the cooling process. By reasonably adjusting the position of the partition, the air flow distribution in the sample chamber 118 can be improved, making the cooling more uniform and efficient.

[0096] The design of the adjustable baffles allows the user to flexibly adjust the spatial layout in the sample compartment 118 according to actual needs, thereby improving the flexibility and adaptability of the system. By optimizing the airflow distribution in the sample compartment 118, the adjustable baffles help to achieve a more uniform and efficient cooling effect, thereby improving the overall performance of the system. The design of the adjustable baffles allows the user to easily adjust the spatial layout in the sample compartment 118, reducing the difficulty and complexity of operation. By meeting the user's storage needs for samples of different sizes and shapes, the adjustable baffles enhance the user's experience and satisfaction.
