Description

Technical Field

[0001] This invention relates to the field of constant temperature heating, and in particular to a method and apparatus for a thermal balance energy storage rapid temperature change constant temperature water bath, especially a programmable thermal balance energy storage rapid temperature change constant temperature water bath apparatus. Background Technology

[0002] Currently, traditional scientific experimental constant temperature water bath equipment uses electric heating and compressors for heating and cooling. The heating and cooling process is relatively slow, and the temperature change takes a long time. In addition, the water bath releases byproducts into the space during heating or cooling, resulting in the waste of energy. At the same time, the heat released into the space will also disrupt the temperature field of the laboratory, thereby increasing the load on the laboratory air conditioning and causing secondary energy consumption.

[0003] Furthermore, traditional constant-temperature water bath devices have slow heating and cooling processes, taking a long time to stabilize at the designated temperature with difficulty in controlling precision. This makes scientific experiments lengthy, slow-progressing, and inefficient, and the long waiting time consumes a significant amount of the experimenter's time and patience. Additionally, for some experiments, the extended time can alter the samples.

[0004] For experimental samples with a large heat capacity, the temperature change and stabilization of the constant temperature water bath will be slower, while reducing the capacity of the constant temperature water bath will increase the temperature instability.

[0005] Therefore, the inventors intend to develop a solution that can solve the problem of storing and balancing the use of cold and hot energy, realize the programmability of temperature testing, shorten the time of temperature rise and fall and the experimental process, and basically do not change the temperature field of the test site during the experimental process. Summary of the Invention

[0006] To achieve the above objectives, the main technical problem to be solved by the present invention is to provide a simple, low-cost, and easy-to-operate thermostatic water bath device based on thermal balance energy storage for rapid temperature change, so as to provide a programmable rapid thermostatic water bath for scientific experiments, so that it does not need to apply electric heating and cooling technologies alternately.

[0007] The key concept of this invention lies in using methods such as refrigerant compression and heat release in a refrigeration unit, and refrigeration recirculation, to transfer thermal energy from a cold water tank (cold energy storage tank) to a hot water tank (thermal energy storage tank), thereby separating and storing cold and hot energy separately. This achieves thermal balance between the two storage tanks (energy storage tanks) without diffusion to the outside, thus not changing the laboratory temperature field. When the water bath used for the experiment is heated or cooled, reversible temperature changes in the water bath can be achieved by separately adjusting the energy of the cold and hot water tanks (cold and hot energy storage tanks), and these temperature changes will be rebalanced.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A method for rapid temperature change and constant temperature water bath with thermal balance energy storage involves separating and pre-storing the cold and heat energy used for energy exchange in the water bath to maintain thermal balance without diffusion to the outside world. This provides reserve energy for rapid temperature change without disrupting the temperature field of the experimental environment or increasing the temperature load on the experimental environment. When the water bath carrying the experiment is heated or cooled, the stored cold and heat energy can be separately called to achieve reversible temperature change of the water bath.

[0010] Meanwhile, a thermal balance energy storage rapid temperature change constant temperature water bath device is also provided, which mainly includes: constant temperature water bath unit, cold and hot energy separation and storage unit and intelligent control core.

[0011] The intelligent control core controls the pre-storage of thermal and cold energy in the thermal energy separation storage unit, and controls the water bath (6) to call the stored cold and hot energy for the constant temperature water bath unit according to the demand to achieve reversible temperature change;

[0012] The present invention relates to a thermal balance energy storage rapid temperature change constant temperature water bath device, wherein the intelligent control core is composed of a programmable central control actuator, which can be an intelligent electronic module (10) constructed by a computer and a display.

[0013] The present invention relates to a thermal balance energy storage rapid temperature change constant temperature water bath device, wherein the intelligent control core (intelligent electronic module (10)) utilizes the isolation exchange orientation of the thermal energy separation storage unit to change the medium temperature of the constant temperature water bath (6) in the constant temperature water bath unit by exchanging the stored cold and heat energy, and can accurately control the rise and fall and uniformity of the medium temperature in the water bath (6) through PID algorithm, wherein the medium is usually selected as water.

[0014] Preferably, the hot and cold energy is exchanged with the circulation system (7) of the water bath through the heat exchanger (5) of the constant temperature water bath unit, and the flow field of the water bath (6) is disturbed by the circulation system (7) to achieve isolation heat exchange.

[0015] The hot and cold energy separation and storage unit may include a thermal energy storage tank (2), a cold energy storage tank (3), a hot and cold exchange unit (including a hot and cold exchange pump (4) and a solenoid valve bridge), and a hot and cold energy separation unit;

[0016] The constant temperature water bath unit includes a constant temperature water bath (6), a circulation system (7), a heat exchanger (5), and a circulation medium;

[0017] The cold and hot energy separation unit may include: a compressor (1), a gas-liquid separator, a liquid storage tank, an expansion valve, and a drying filter;

[0018] It also includes the corresponding pipes for each circulation system.

[0019] During operation, the refrigerant is compressed and releases heat through the compressor (1). When the refrigerant loses heat, liquefies, and then evaporates, it absorbs heat (refrigeration). These two types of energy are basically symmetrical in numerical terms. This innovation collects and stores these thermal and cold energies in thermal energy storage tank (2) and cold energy storage tank (3) respectively to complete energy storage. When starting the constant temperature water bath to raise or lower the temperature, these stored energies are used to indirectly heat the water in the constant temperature water bath (6) via the electromagnetic valve bridge, water pump (4), and energy exchanger (5), forming a controllable and reversible energy exchange chain.

[0020] When the stored heat or cold energy is insufficient to complete the temperature rise and fall of the constant temperature water bath, the compressor refrigeration unit replenishes the energy of the heat storage tank (2) or the cold storage tank (3) to complete the temperature adjustment of the constant temperature water bath.

[0021] The process of heating / cooling the constant temperature water bath involves the energy carried by the refrigerant constantly in a closed loop of refrigerant compression and heat release—heat energy storage tank (2)—refrigerant heat absorption—cold energy storage tank (3) returning to the compressor (1). It does not release cold and heat to the external space, forming separate storage of cold and heat energy. It separates and stores all heat energy and cold energy, and does not directly release cold or heat to the surrounding space, so it does not change the temperature field stability of the surrounding scientific experiment.

[0022] The constant temperature water bath designed in this invention operates in the range of -10 to +50℃ and utilizes cold and hot energy storage for reversible heating and cooling, while the energy can be used in a closed-loop balance.

[0023] During the isothermal and temperature-changing processes, the entire experimental process, the vector direction and step size of the cooling, and the whole process can be programmed for continuous operation.

[0024] This technology features energy saving, integration, no impact on the laboratory temperature field, significantly shortened experimental time, high heat exchange efficiency, programmable operation, and the ability to achieve rapid temperature changes in large steps, thus shortening the test time.

[0025] Compared with the prior art, the thermal balance energy storage rapid temperature change constant temperature water bath device and method of the present invention have at least the following advantages:

[0026] Beneficial effects:

[0027] 1. The thermal balance energy storage rapid temperature change constant temperature water bath device of the present invention adopts cold and hot separation off-site storage. This technology shifts and separates the cold and hot energy in the original water tank, so that the cold and hot energy is balanced and there is no overflow. Therefore, it does not change the temperature field of the experimental environment, nor does it change the heat load of the experimental environment. At the end of the experiment, the stored cold and hot media offset and balance to restore the ambient temperature under the original scenario, without forming a delayed temperature field change.

[0028] 2. This invention utilizes energy harvesting and separates thermal and cold energy for off-site storage. By selectively releasing and exchanging energy, cold or thermal energy is selectively exchanged with experimental conditions to rapidly change the target temperature of the experimental water bath. The target temperature of the water bath is achieved in a short time using heat balance exchange technology, saving a lot of experimental waiting time and sample creep. It can change the experimental process and save scientific experimental time and cycle.

[0029] 3. The device of the present invention operates through an intelligent control core, which can monitor the temperature changes of cold and hot energy storage throughout the process and automatically enable / disable the control.

[0030] 4. The temperature field of the water bath can be adjusted by an industrial control computer (intelligent control core) according to the experimental example of the experimental target object. The forward and reverse directions of the temperature, the temperature change span, the transition time, the holding time, and the temperature control accuracy can be programmed to realize the programming settings of the entire experimental process. This makes the entire experimental process continuous and seamless, which is an innovation of the existing water bath experimental device. It not only has the advantages of rapid temperature change and high accuracy in the water bath experiment, but also eliminates the need for human intervention and waiting in the intermediate process by means of programmability, realizing the goal that modern scientific experiments need but cannot achieve.

[0031] 5. This invention utilizes the graphical coordinates of an industrial control computer to achieve intelligent settings, greatly reducing the reliance on programming expertise. Users can complete the process simply by touching or clicking the interface UI, making it self-taught. Furthermore, the entire system has AI functions for self-learning and memorization, enabling user-friendly human-computer interaction.

[0032] Especially for projects with experimental data sensing ports, this invention also features automatic experimental data recording, superimposing the recorded data onto the temperature field coordinates to form intuitive temperature variable data patterns. The virtual instrument function of this invention can be used to complete experimental report analysis such as characteristic curves, histograms, topographic maps, and pie charts of data variables, directly generating analysis reports without human intervention. This is achieved based on the powerful software and hardware support of this system, enabling the thermal balance energy storage rapid temperature-changing constant temperature water bath device to realize virtual instrument functions. This allows the system to achieve a leap forward, outputting objective and impartial experimental results.

[0033] The following description, in conjunction with the accompanying drawings, further illustrates the embodiments and applications of the thermal balance energy storage rapid temperature-changing constant temperature water bath device of the present invention. Attached Figure Description

[0034] Figure 1 This is a schematic diagram of the thermal balance energy storage rapid temperature change constant temperature water bath device of the present invention. Detailed Implementation

[0035] To clearly illustrate the above effects and their advantages, a specific embodiment will be described in detail below.

[0036] like Figure 1 The image shown is a schematic diagram of a thermal balance energy storage rapid temperature-changing constant temperature water bath device according to a specific embodiment of the present invention. Figure 1 As shown, the thermal balance energy storage rapid temperature change constant temperature water bath device of the present invention includes a compressor 1, a thermal energy storage tank 2, a cold energy storage tank 3, a cold and heat exchange water pump 4, a cold and heat exchanger 5, a constant temperature water bath 6, a circulation system 7, an electronic control module 10, and a gas-liquid separator, a liquid storage tank, an expansion valve, and a drying filter, etc.

[0037] The unit comprises a thermal energy storage tank 2, a cold energy storage tank 3, a heat exchange unit, and a heat and cold energy separation unit. The heat exchange unit includes a heat exchange water pump 4 and a solenoid valve bridge. The constant temperature water bath unit includes a constant temperature water bath 6, a circulation system 7, a heat exchanger 5, and a circulation medium (water in this specific embodiment). The heat and cold energy separation unit includes a compressor 1, a gas-liquid separator, a liquid storage tank, an expansion valve, and a drying filter, as well as pipes in their respective circulation loops.

[0038] During operation, to ensure the collection of high and low temperature energy and prevent its diffusion to the outside, the cold and hot energy separation and storage unit, in this specific embodiment, uses compressor 1 to compress the refrigerant and discharge (release) high-temperature, high-pressure gas. The heat exchange pipe of the high-temperature gas heat energy storage tank exchanges heat with the special medium inside the heat energy storage tank, releasing (transferring) the high temperature gas. Vertical convection occurs in the heat energy storage tank 2, forming a uniform temperature field. The refrigerant, after releasing heat, passes through a drying filter and enters the expansion valve to regulate its flow rate. In the heat exchanger inside the cold energy storage tank, evaporation occurs. The heat exchanger absorbs heat from the medium in the cold energy storage tank 3 and... The refrigerant gradually cools from low to high temperature under the flow regulation of the expansion valve. The refrigerant flowing out of the heat exchanger enters the gas-liquid separator and then returns to the compressor to complete a heating and cooling cycle. This process is repeated to collect and store heat and cold energy in the heat storage tank 2 and the cold storage tank 3. The electronic control module monitors the cooling and heating process in real time and monitors the temperature inside the heat and cold storage tanks. The compressor stops working when the temperature inside the storage tank reaches equilibrium through PID (proportional-integral-derivative controller). When there is an energy margin, the compressor automatically starts to separate the heat and cold, thus achieving the purpose of cooling, heating, collection, storage and heat preservation.

[0039] Specifically:

[0040] In the stage of separating hot and cold energy, the compressor 1 compresses the refrigerant to generate heat release (heating), and absorbs heat when the refrigerant loses heat, liquefies, and then evaporates (cooling). The energy generated by these two processes is basically symmetrical in value. This invention collects and stores these hot and cold energies in the hot energy storage tank 2 and the cold energy storage tank 3 respectively to complete energy storage.

[0041] When the constant temperature water bath is started to rise or fall, the stored energy is used to indirectly heat up or lower the water temperature of the constant temperature water bath 6 through the solenoid valve bridge, water pump 4 and energy exchanger 5, forming a controllable and reversible energy exchange chain.

[0042] When the stored heat or cold energy is insufficient to complete the temperature rise and fall of the constant temperature water bath 6, the compressor refrigeration unit will continue to replenish the energy of the heat storage tank 2 or the cold storage tank 3 to adjust the temperature of the constant temperature water bath to the set value.

[0043] In this specific embodiment, the constant temperature water bath of the present invention operates within the range of -10 to +50℃, utilizing cold and hot energy storage for reversible heating and cooling, while achieving closed-loop balanced energy use. When it is necessary to heat or cool the constant temperature water bath 6, the electronic control module 10 controls the exchange water pump 4 (frequency conversion), which, through a solenoid valve, selects the energy source channel bridge and, via the heat exchanger 5, uses specialized shaped pipe fittings to perform heat exchange on the medium within the constant temperature water bath 6. Temperature control is achieved through precise PID calculations, forming a uniform temperature field under the action of the circulation system 7. Since the PID controls the frequency conversion pump of the constant temperature water bath heat exchange, compared to existing methods of controlling heating wires or chillers, the present invention uses PID control of the frequency conversion pump to achieve large dynamic approximation and fine-tuning after approach, resulting in a fast and precise effect.

[0044] The hardware device of this invention operates through an intelligent control core that monitors temperature changes in the cold and hot energy storage process and automatically enables / disables the control. During constant and variable temperature processes, the entire experimental process, including its progression, step size, and overall execution, can be programmed for continuous operation.

[0045] The operation of the energy separation and storage system of this invention is accomplished by a programmable central control actuator. In this specific embodiment, the programmable central control actuator is an intelligent electronic module 10 constructed from a computer and a display. The entire cold and hot storage preparation and water bath variable regulation are driven by a frequency converter with a controller and a PID control device. The central control actuator receives communication servo commands from the host computer. The intelligent electronic module 10 has a configurable and editable human-computer interaction platform, which allows for the setting of required parameters on the UI interface in the form of graphical coordinates, touch, or mouse, according to the requirements of the test procedure.

[0046] The entire process of cold and hot separation storage and operation, as well as the temperature change process of the water bath, forms a complete experimental closed loop under the linkage of the computer and control actuators. Furthermore, the operation of all the above components is monitored by an electronic control module. This cooling and heating device is not limited to experimental examples; it can be applied to various instruments and equipment requiring cooling and heating, including but not limited to environmental test chambers and constant temperature test baths, ensuring rapid response to the measurement environment and eliminating noise, energy leakage, and disruption of the temperature field of the test environment.

[0047] The thermodynamic balance energy storage rapid temperature change constant temperature water bath device constructed by the technology of this invention has no leakage of cold and hot energy. It utilizes the separate storage of cold and hot energy to store heat and cold energy separately and release and exchange them selectively. It selectively exchanges cold or heat energy with experimental conditions to change the experimental temperature. It is suitable for all devices that do not need to disrupt the temperature field of the experimental environment, increase the temperature load of the experimental environment, or need to change the experimental process to save scientific experimental time and cycle.

[0048] The temperature field of the water bath is adjusted by an industrial control computer based on the experimental example of the target object. The forward and reverse temperature, temperature change range, transition time, holding time, and temperature control accuracy can be programmed to achieve the programming settings of the entire experimental process. This makes the entire experimental process continuous and seamless, which is an innovation in common water bath experimental devices. Not only does the water bath experimental process change temperature quickly, with high precision and programmability, but it also eliminates the need for human intervention and waiting in the middle process. This is the kind of creativity that modern scientific experiments need but cannot achieve.

[0049] The computer also has functions such as automatic recording of experimental results, temperature interpolation of experimental data, background data queue, continuous playback, and generation of experimental reports such as coordinates and topographic maps.

[0050] In scientific experiments, the present invention allows for setting the vector direction, step size, and duration of temperature changes in the water bath, and enables programmable step sequence and cycle of multiple temperature points; furthermore, experimental process information can be recorded, marked, and used to generate big data analysis.

[0051] The heat exchange structure constructed by the cold and hot energy storage of the present invention is not limited to a temperature bridge, but can include device schemes that can include multiple circulating pumps and pipeline loops. The endurance of the cold and hot energy is not limited to a single cooling mode, but includes a composite energy endurance mode using cold and hot energy storage, such as electric heating, to achieve a wider temperature range.

[0052] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
