Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, and in particular to an in-situ observation electrolytic cell with temperature control function. Background Technology

[0002] Current research on zinc dendrites mainly relies on glass cuvettes, electrolyte cells, or simple open acrylic cells. These devices typically only provide a transparent observation window and basic electrode clamping. An external constant current source drives the electrodeposition reaction, resulting in the reduction and deposition of zinc ions on the cathode and the oxidation and dissolution of zinc on the anode, forming a dendritic structure. The experimenter observes the electrode surface in real time using a stereomicroscope or a long-distance microscope.

[0003] However, these devices generally lack temperature control capabilities, and experimental conditions are easily affected by fluctuations in ambient temperature and humidity. Existing devices cannot stably control the temperature, and there is usually a problem that the temperature at the heat source point is slightly higher and the temperature is lower further away from the heat source point. At the same time, most existing devices only have heating functions and lack effective cooling methods. As a result, some low-temperature experiments cannot obtain effective experimental data, and the lack of uniform heating methods under high-temperature conditions leads to enhanced electrolyte convection and poor repeatability of experimental results.

[0004] In view of this, there is an urgent need for an in-situ observation electrolytic cell with temperature control function to solve the above problems. Utility Model Content

Specific Embodiments

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see the appendix Figure 1-4 An in-situ observation electrolytic cell with temperature control function, comprising:

[0024] The electrolytic cell 1, the outer protective shell 2, at least one set of heating components 3 and temperature sensor 4 are provided. The electrolytic cell 1 is detachably connected to the inside of the outer protective shell 2, and a temperature regulating cavity 5 is formed between the electrolytic cell 1 and the outer protective shell 2. The temperature regulating cavity 5 is filled with a temperature conducting medium 6. The heating components 3 are located in the temperature regulating cavity 5 and are connected to the outer protective shell 2. The temperature sensor 4 is installed in the electrolytic cell 1.

[0025] Considering that existing heating / cooling devices typically use a point heat source, where heat diffuses from a point to a surface, this method results in temperatures that are higher near the heat source and lower further away. Consequently, the temperature measured by the temperature sensor 4 in such devices often has a large error, leading to unstable experimental results. This invention combines an electrolytic cell 1 with an outer protective shell 2, forming a temperature-regulating cavity 5 between the bottom of the electrolytic cell 1 and the outer protective shell 2. A temperature-conducting medium 6 is poured into this cavity to achieve uniform heating / cooling. The point heat source preferentially heats the temperature-conducting medium 6, which then surrounds the electrolytic cell 1 to heat / cool the electrolyte within, reducing temperature deviations at different locations. Furthermore, during initial heating / cooling of the electrolyte, the temperature can be quickly adjusted by replacing the temperature-conducting medium 6 with one of the appropriate temperature. The heating / cooling device then maintains the temperature-conducting medium 6 at a constant temperature. This method effectively shortens the experimental time and saves on experimental costs.

[0026] Specifically, the heating assembly 3 includes a cylindrical heat-conducting outer shell 30, a heating rod 31, and a connecting plate 32. The cylindrical heat-conducting outer shell 30 is fixedly connected to the bottom wall of the temperature regulating cavity 5. One end of the heating rod 31 is fixedly connected to the connecting plate 32, and the other end passes through the bottom wall of the outer protective shell 2 and is located inside the cylindrical heat-conducting outer shell 30. The connecting plate 32 is detachably connected to the bottom of the outer protective shell 2, and the connecting plate 32 is provided with an external connecting wire 320. Considering that different experiments have different temperature requirements, and that existing temperature control systems on the market usually focus on temperature... Most devices that can simultaneously increase or decrease temperature either have excessively high prices or limited temperature regulation capabilities. Therefore, this invention employs an independent heating component 3 and a cooling device. To facilitate the installation and removal of the heating component 3, the cylindrical heat-conducting shell 30 and the heating rod 31 are separated. The cylindrical heat-conducting shell 30 is fixed inside the temperature regulation cavity 5. When the electrolyte needs to be heated to ensure a constant temperature, the heating rod 31 is installed inside the cylindrical heat-conducting shell 30 via the connecting plate 312.

[0027] Specifically, the inner diameter of the cylindrical heat-conducting outer shell 30 matches the outer diameter of the heating rod 31, and the cylindrical heat-conducting outer shell 30 is made of metal. Since the temperature conduction medium 6 needs to indirectly conduct heat on the heating rod 31 through the cylindrical heat-conducting outer shell 30 when raising the temperature, in order to avoid temperature loss during the conduction process, the inner diameter of the cylindrical heat-conducting outer shell 30 should be as close as possible to the outer diameter of the heating rod 31. At the same time, in order to improve the thermal conductivity, the cylindrical heat-conducting outer shell 30 should be made of a metal with good thermal conductivity.

[0028] Specifically, the outer protective shell 2 has a liquid inlet hole 20 on its side wall and a liquid outlet hole 21 at its bottom. The liquid inlet hole 20 and the liquid outlet hole 21 are equipped with matching plugs 22. Considering that replacing the temperature conduction medium 6 can help regulate the temperature of the electrolyte in the electrolytic cell 1, the outer protective shell 2 has a liquid inlet hole 20 and a liquid outlet hole 21 for replacing the temperature conduction medium 6 in order to facilitate the replacement of the temperature conduction medium 6.

[0029] Specifically, a display screen 23 is also provided on the side wall of the outer protective shell 2, and the display screen 23 is connected to the temperature sensor 4 in the circuit. In order to facilitate the monitoring of the real-time temperature of the electrolyte in the electrolytic cell 1, a display screen 23 is provided on the outer protective shell 2, and the display screen 23 is connected to the temperature sensor 4. It should be noted that the temperature sensor 4 is equipped with an external power supply that matches it.

[0030] Specifically, a cold plate 7 is placed at the bottom of the temperature regulating cavity 5, and the cold plate 7 is provided with S-shaped copper cold pipes 70, and the copper cold pipes 70 are filled with a low-temperature ethylene glycol-water mixture.

[0031] Considering that some tests require the electrolyte to be in a low-temperature environment below room temperature, a cold plate 7 is arranged in the temperature regulating cavity 5. Meanwhile, in order to enhance the cooling effect of the cold plate 7, S-shaped arranged red copper cooling pipes 70 are adopted in the cold plate 7, and the temperature conduction efficiency is improved by filling low-temperature ethylene glycol-water mixed solution into the red copper cooling pipes 70. It should be noted that the cold plate 7 itself does not have refrigeration capacity, so the cold plate 7 needs to be externally connected with refrigeration equipment, such as micro air conditioners or small refrigerators commonly used in laboratories. The connecting pipe between the refrigeration equipment and the cold plate 7 can pass through the liquid inlet hole 20, and if there is a demand for customized equipment, a special hole for pipe penetration can be opened on the side wall of the outer protective shell 2.

[0032] Specifically, a "square-ring" shaped sealing groove 10 is provided on the top wall of the electrolytic cell 1, and a sealing ring 100 is placed in the "square-ring" shaped sealing groove 10;

[0033] The temperature regulating cavity 5 in the present utility model can not only realize temperature regulation by filling a heat transfer medium 6 and installing a refrigeration / heating device therein, but also has a certain thermal insulation capacity. Therefore, a "square-ring" shaped sealing groove 10 is provided on the top wall of the electrolytic cell 1, and a sealing ring 100 is placed in the groove for sealing.

[0034] Specifically, a base 24 detachably connected to the outer protective shell 2 is provided at the bottom of the outer protective shell 2.

[0035] The above description is only preferred specific implementation modes of the present utility model, and the protection scope of the present utility model is not limited thereto. Any equivalent replacement or modification made by a person skilled in the art within the technical scope disclosed by the present utility model according to the technical scheme and the concept of the present utility model shall be covered within the protection scope of the present utility model.
