[0027] Example 1:
[0028] In this embodiment, a phase change isothermal experimental device in a confined space, such as... Figure 1 As shown, the system includes a simulation room 1, a phase change temperature control module 2, a heat source module 3, a cooling module 4, and a heating device module 5. Specifically, the cooling module 4 and the heating device module 5 are installed inside the simulation room 1. The cooling module 4 is used to provide cooling for the room, and the heating device module 5 is used to simulate the heating of the equipment in the simulation room 1. The simulation room 1 includes a roof 6, a floor 7, and an outer shell 8. The outer shell 8 has a door 18 on its front. The heat source module 3 is installed on the outside of the outer shell 8 and is used to simulate a high-temperature external environment. The phase change temperature control module 2 is installed on the inside of the roof 6, the inside of the outer shell 8, and the floor 7. The phase change temperature control module 2 is used to exchange heat with the cold air output by the cooling module 4 to store some of the cold energy. A floor support 9 is provided between the floor 7 and the phase change temperature control module 2, which provides a ventilation gap between the floor 7 and the phase change temperature control module 2, increasing the heat exchange area of the phase change temperature control module 2.
[0029] By adopting this structure, the test device is decomposed into multiple modules, which can be spliced together according to the simulation scenario to complete the simulation. The volume design is flexible and can be adjusted according to the actual simulation needs to simulate different scenarios. In this way, the performance changes of the phase change temperature control module 2 mentioned above under different scenarios can be monitored, which significantly improves the test efficiency and test accuracy, making the utility model more practical.
[0030] In this embodiment, the phase change temperature control module 2 includes a plate 10 and a phase change cold storage plate 11. The plate 10 is fixedly installed on the inner side of the roof 6, the inner side of the outer shell 8, and the floor 7. A U-shaped groove rail 12 is provided on one side of the plate 10. The two ends of the phase change cold storage plate 11 are slidably connected in the U-shaped groove rail 12. Multiple phase change cold storage plates 11 are laid flat on the plate 10 through the U-shaped groove rail 12, so that the phase change cold storage plates 11 fill the interior of the simulation room 1 to exchange heat with the cold air released by the refrigeration module 4 and store part of the cold energy.
[0031] Specifically, the aforementioned phase change cold storage plate 11 is a hollow plate, and it is filled with a phase change material. The phase change material is an organic mixture of lipids and alcohols. Based on nanocrystal technology, it changes the state of matter and can absorb or release a large amount of heat energy under constant temperature. Its temperature control or cold storage principle is a completely physical change. When the phase change material undergoes solid-liquid or liquid-vapor phase transition, it absorbs a large amount of latent heat and maintains its temperature constant at its inherent phase transition point temperature. This allows it to absorb the heat released by communication equipment and suppress the rise in ambient temperature, or absorb the cold energy of nighttime cold sources for inter-period supply. It can be used during the day and can also be used as a backup cold source for emergency use. It features customizable temperature, stable performance, high energy storage density, and green safety and environmental protection. As an optimization, the phase change cold storage plate 11 is equipped with a breathing balance valve 13. The breathing balance valve 13 connects the internal and external spaces of the phase change cold storage plate 11 and is used to balance the pressure between the phase change material space inside the phase change cold storage plate 11 and the external environment. This prevents the phase change cold storage plate 11 from overpressure rupture or decompression deformation caused by the volume change of the phase change material during phase change. The phase change cold storage plate 11 is made of polyethylene composite material.
[0032] In this embodiment, the phase change cold storage plate 11 of the phase change temperature control module 2, which is laid on the floor 7, has a plurality of protruding ridges 14 extending from its bottom side. The protruding ridges 14 are hollow and communicate with the interior of the phase change cold storage plate 11. The plurality of protruding ridges 14 are parallel and spaced apart. The protruding ridges 14 increase the contact area with air, thereby improving the heat exchange efficiency between the phase change cold storage plate 11 and the ground air at this location. At the same time, the spaced arrangement of the plurality of protruding ridges 14 optimizes the airflow channel between the phase change cold storage plate 11 and the floor 7, reduces cold loss, improves heat exchange efficiency, and allows more cold energy to be stored in the phase change cold storage plate 11.
[0033] As a specific implementation of this embodiment, the heat source module 3 is a graphene heating film. The graphene heating film is laid on the outside of the outer shell 8. The graphene heating film is used to simulate the external high temperature environment. It generates heat based on the excellent electrical and thermal conductivity of graphene. When the device is turned on, the graphene heating film is heated to the set temperature point to simulate solar radiation. The simulated heat source method can be changed according to the simulated scenario. The specific temperature and simulated heat source method are customized according to the simulated scenario.
[0034] In this embodiment, the above-mentioned cooling module 4 is a precision air conditioner for computer rooms with an input power of 8000W. During operation, the input power can be adjusted in real time according to the actual operating conditions.
[0035] In this embodiment, the heating device module 5 is equipped with a resistance wire heater with a sliding rheostat, and the heating power is not less than 5000W. It can be adjusted in real time according to the load requirements. The bottom of the heating device module 5 is equipped with universal wheels with brakes, which can freely adjust the fixed position of the heating device module 5 as needed. The heating device module 5 includes a simulated power cabinet and a simulated cabinet.
[0036] In this embodiment, a backup power supply 16 and a power rack 17 are also provided in the above-mentioned simulation room 1. The backup power supply 16 is installed in the power rack 17. The bottom of the power rack 17 is provided with casters with brakes. The backup power supply 16 is generally a lithium-ion battery, but can also be a lead-acid battery, lithium iron phosphate battery, etc., to ensure continuous power supply to critical equipment when power supply is abnormal.
[0037] In this embodiment, a monitoring module is also included. The monitoring module includes a temperature and humidity sensor 19 and an electricity meter 15. The temperature and humidity sensor 19 is used to monitor the temperature and humidity changes in the simulation room 1, and the electricity meter 15 is used to monitor the power consumption of the cooling module 4 and the heating device module 5. The temperature and humidity sensor 19 and the electricity meter 15 can be installed in the roof 6, floor 7, shell 8, or inside the heating device module 5 of the simulation room 1, and upload temperature data and energy consumption data to the monitoring terminal for aggregation in real time.
[0038] The simulation process of the aforementioned phase change isothermal test device in a confined space includes temperature simulation when the refrigeration system is turned on and temperature simulation when the refrigeration system is turned off:
[0039] Temperature simulation was performed when the cooling system was turned on. The cooling module 4 was kept on. At the start of the experiment, the graphene heating film and resistance wire heater were turned on. The graphene heating film began heating at the set temperature, and the internal temperature began to rise. The temperature and humidity sensor 19 and the cooling module 4 transmitted recorded data every 5 seconds. The recorded data included the external temperatures of each side of the outer casing 8, the temperature of the roof 6, the top temperature of the heating device module 5, the temperature of the floor 7, and the temperature of the phase change temperature control module 2. The rate of temperature rise and the temperature changes inside the simulation room 1 were observed. The time it took for the temperature to reach the alarm point while the cooling module 4 was on was recorded, completing the temperature simulation with the cooling module 4 on. The experiment yielded data on the temperature changes and energy consumption inside the simulation room 1 with the cooling module 4 on. Based on the temperature change data and the time it took for the temperature to reach the alarm point in the simulation room 1, the temperature control and cooling effect of the phase change material when the cooling module 4 and the phase change temperature control module 2 were used together was calculated. By comparing the energy consumption without and after the phase change temperature control module 2 was installed, the energy-saving effect of the phase change temperature control module 2 could be calculated.
[0040] Temperature simulation was performed with the cooling system off and other parameters unchanged. The cooling module 4 was turned off, and the experiment was started. The resistance wire heater was activated, and the graphene heating film began heating to the set temperature, causing the internal temperature to rise. The temperature and humidity sensor 19 transmitted recorded data every 5 seconds, including the external temperatures of each side of the outer casing 8, the roof temperature 6, the top temperature of the heating device module 5, the floor temperature 7, and the phase change temperature control module 2. The rate of temperature rise and the temperature change within the simulated computer room 1 were observed. The time it took for the temperature to reach the alarm point when the cooling module 4 was on was recorded, completing the temperature simulation with the cooling module 4 off. At the end of the experiment, temperature change data and energy consumption data were obtained when the phase change temperature control module was used alone. By comparing the temperature data in the computer room without the phase change temperature control module with the temperature data with the phase change temperature control module installed, the cooling and temperature control effect of the phase change temperature control module could be calculated. By comparing the temperature change data inside the computer room when the cooling module 4 is turned on and when the cooling module 4 is turned off, under the condition that the phase change temperature control module is installed, the temperature control and cooling effect when the phase change temperature control module and the cooling module 4 are combined can be calculated, as well as the temperature control and cooling effect when the phase change temperature control module is used alone. The power consumption of the phase change temperature control module combined with the cooling module 4 and without the cooling module 4 can also be calculated. At the same time, when the phase change material is in a solid state of cold storage, the cooling module 4 is turned off, and the time to rise to the alarm temperature is observed. This verifies that when the cooling module 4 is in the off state in the computer room, the phase change temperature control module can be used as a backup cold source.
[0041] It is worth noting that all the above data are transmitted remotely. By using the temperature and humidity sensor 19 and the remote meter 15 to collect and analyze various data inside the computer room, the effects of the phase change temperature control module 2 on the temperature change and power consumption of the cooling module 4 inside the computer room are obtained, depending on the location of the phase change temperature control module 2 inside the computer room and the number of phase change temperature control modules 2 installed, and the start or stop of the cooling module 4 inside the computer room.
[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
