Description

A portable temperature control device for use in conjunction with an electrochemical workstation for testing. Technical Field

[0001] This utility model belongs to the field of constant temperature device technology, specifically relating to a portable constant temperature device for use in conjunction with an electrochemical workstation for testing. Background Technology

[0002] Cyclic voltammetry testing of button cells is an important method for studying their electrochemical performance. Current methods involve connecting an electrochemical workstation to a computer. The workstation has a built-in four- or five-electrode test lead, and an external clamp is required to hold the button cell in place. This approach limits testing to room temperature and cannot accommodate arbitrary temperature conditions.

[0003] When testing batteries, if you want to set a constant temperature, you can use a constant temperature chamber. However, constant temperature chambers are often large in size to meet the needs of a large number of tests. The temperature range of a constant temperature chamber is 5 to 60℃ and -70 to 150℃ (non-standard customization). The chamber volume is large and can hold dozens or even hundreds of batteries for testing at the same time.

[0004] If a thermostat and an electrochemical workstation are used together, wires need to be run from the electrochemical workstation to the fixtures inside the large thermostat to control the specific temperature for testing. Testing one battery at a different temperature inevitably affects the other batteries, leading to unnecessary experimental errors and interfering with the results. Furthermore, thermostats are expensive, bulky, and require complex wiring. Summary of the Invention

[0005] The present invention addresses the problem of providing a portable constant temperature device for use in conjunction with an electrochemical workstation, thereby solving the problems of existing constant temperature chambers being expensive, bulky, cumbersome, having complex wiring, and inconvenient to operate, which affect the accuracy of normal testing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A portable constant temperature device for use in conjunction with an electrochemical workstation includes an outer shell, an inner shell, a cover plate, a heating structure, and a cooling structure. The inner shell is fixedly connected to the middle of the inner shell, and the cover plate is connected to the upper end of the outer shell. A lifting structure is provided at the lower end of the inner shell, and a base plate is connected to the upper end of the lifting structure. The upper surface of the base plate is provided with a clamp for holding a battery, and the clamp is provided with a connecting wire for connecting to the electrochemical workstation. The lifting structure can move the base plate up and down. When the user wants to place a button battery on the clamp, the user can extend the base plate from the inner shell through the lifting structure, then use the clamp to hold the button battery, and finally retract the base plate for testing. This structure can improve the efficiency of use, is simple and convenient to operate, and is not limited by the small size of the inner shell, thus improving experimental efficiency.

[0008] A heating structure is provided on one side of the inner shell and inside the outer shell. The heating structure works with the inner shell to increase the temperature inside the inner shell. A cooling structure is provided on the other side of the inner shell and inside the outer shell. The cooling structure works with the inner shell to reduce the temperature inside the inner shell.

[0009] The portable temperature control device used in conjunction with the electrochemical workstation has a cover plate connected to the outer shell on one side via a hinge, and the other side of the cover plate engaging with the outer shell via a buckle, facilitating the opening and closing of the cover plate. When the cover plate is closed, the user can secure it with the buckle to ensure the stability of the closed cover plate. The lower end face of the cover plate is provided with a rubber pad for a sealing effect.

[0010] The portable temperature control device used in conjunction with an electrochemical workstation includes a lifting structure comprising a base frame, a scissor lift, and an electric push rod. The base frame is fixedly connected to the outer casing, and the base frame and the base plate are connected via the scissor lift. The scissor lift is equipped with an electric push rod, which drives the extension and retraction of the scissor lift. When the electric push rod extends, it causes the scissor lift to open, raising the base plate. When the electric push rod retracts, it causes the scissor lift to close, lowering the base plate. The principle is the same as that of a scissor lift machine, making it simple and convenient to operate.

[0011] The portable temperature control device used in conjunction with an electrochemical workstation includes a heating structure comprising a heating wire that is uniformly wound around the outer surface or inner wall of the inner shell. The heating wire is connected to a power source and can raise the temperature of the inner shell.

[0012] The portable constant temperature device used in conjunction with the electrochemical workstation for testing includes a refrigeration structure comprising: a micro compressor, a condenser, a capillary tube, and a refrigeration copper tube. One connector of the micro compressor is connected to one end of the refrigeration copper tube, and the other end of the refrigeration copper tube is connected to the condenser via the capillary tube. The condenser is connected to the other connector of the micro compressor, and a cooling fan is provided on the condenser.

[0013] The portable constant temperature device used in conjunction with the electrochemical workstation for testing has a cooling copper tube evenly distributed on the outer surface or inner wall of the inner shell. The outer surface or inner wall of the inner shell is provided with a groove, and the cooling copper tube is disposed inside the groove. The cooling copper tube is disposed inside the groove, which allows for better cooperation between the cooling copper tube and the inner shell and improves the cooling effect.

[0014] The portable temperature control device used in conjunction with the electrochemical workstation for testing has a temperature controller inside its outer shell, which enables the inner shell to maintain a constant temperature.

[0015] Beneficial effects: Compared with the prior art, this application has the following advantages:

[0016] (1) The device is equipped with an inner shell and an outer shell. The inner shell has heating and cooling structures on both sides, which can control the temperature inside the inner shell. The constant temperature device is small in size, easy to operate, and convenient to collect and carry. When connected to an electrochemical workstation, it can test one battery at a time, reduce experimental errors, and improve the accuracy of the experiment.

[0017] (2) The device has a lifting structure in its inner shell. When the user wants to put the button battery on the clamp, the user can use the lifting structure to extend the bottom plate out of the inner shell, then use the clamp to hold the button battery, and finally put the bottom plate back in for testing. This structure can improve the efficiency of use, is simple and convenient to operate, and is not limited by the small size of the inner shell, thus improving the efficiency of the experiment.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Referring to Figures 1-4, this embodiment provides a portable temperature control device for use in conjunction with an electrochemical workstation for testing.

[0027] The device includes an outer shell 1, an inner shell 2, a cover plate 3, a heating structure 4, and a cooling structure 5. The inner shell 2 is fixedly connected to the middle of the inner shell 1. The heating structure 4 and the cooling structure 5 are respectively located on the outer sides of the inner shell 2. The cover plate 3 is provided on the outer shell 1. One side of the cover plate 3 is connected to the outer shell 1 by a hinge, and the other side of the cover plate 3 is engaged with the outer shell 1 by a snap fastener, which facilitates the opening and closing of the cover plate. When the cover plate is closed, the test personnel can fix it with the snap fastener to ensure the stability of the closed cover plate. A rubber gasket is provided on the lower end face of the cover plate 3 to improve the sealing performance of the device.

[0028] The lower end of the inner shell 2 is provided with a lifting structure 6, and the upper end of the lifting structure 6 is connected to the base plate 7. The lifting structure 6 can rise and fall. The lifting structure 6 includes a base frame 601, a scissor lift 602 and an electric push rod 603. The base frame 601 is fixedly connected to the outer shell 1 to ensure the stability of the base frame 601. The base frame 601 and the base plate 7 are connected through the scissor lift 602. The base frame 601 and the scissor lift 602, as well as the base plate 7 and the scissor lift 602, are movably connected to ensure the normal movement of the scissor lift 602. The scissor lift 602 is provided with an electric push rod 603. The electric push rod 603 is provided with a connecting wire. The plug of the connecting wire is located on the outside of the outer shell 1. When in use, the plug can be connected to an external power source to ensure the normal use of the electric push rod 603. The electric push rod 603 drives the extension and retraction of the scissor lift 602, and the principle is the same as the working principle of the scissor lift: when the electric push rod 603 starts the extension operation, it can drive the scissor lift 602 to extend, and the base plate 7 rises under the drive of the scissor lift 602. When the electric push rod 603 starts the retraction operation, it can drive the scissor lift 602 to retract, and the base plate 7 falls under the drive of the scissor lift 602.

[0029] When the lifting structure 6 moves upward or downward, it causes the base plate 7 to rise or fall accordingly. The upper surface of the base plate 7 is equipped with a clamp 8 for holding the battery, and the clamp 8 has a connecting wire for connecting to the electrochemical workstation. The length of the connecting wire is sufficient to accommodate the distance difference caused by the rise or fall of the base plate 7. The base plate 7 is raised and extended from the inner shell 2 by the lifting structure 6, then the button battery is clamped by the clamp 8, and finally the base plate 7 is lowered and retracted into the inner shell 2. The lifting structure 6 improves efficiency, is simple and convenient to operate, and is not limited by the small size of the inner shell 2, thus improving experimental efficiency.

[0030] The heating structure 4 works in conjunction with the inner shell 2 to increase the internal temperature of the inner shell 2. The heating structure 4 includes a heating wire 401, which is connected to a battery located on one side of the outer shell 1. The heating wire 401 is evenly wound around the outer surface of the inner shell 2. The heating wire can also pass through the side wall of the inner shell 2 and be evenly arranged on the inner side wall of the inner shell. The heating wire 401 can raise the temperature of the inner shell 2. A temperature controller is provided inside the outer shell 1 and is connected to the battery to ensure the normal operation of the temperature controller. The temperature controller can control the temperature of the inner shell 2 to reach a constant temperature.

[0031] The refrigeration structure 5 works in conjunction with the inner shell 2 to reduce the temperature inside the inner shell 2. The refrigeration structure 5 includes a micro compressor 501, a condenser 502, a capillary tube 504, and a refrigeration copper tube 505. One connector of the micro compressor 501 is connected to one end of the refrigeration copper tube 505, and the other end of the refrigeration copper tube 505 is connected to the condenser 502 through the capillary tube 504. The condenser 502 is connected to the other connector of the micro compressor 501. A cooling fan 503 is provided on the condenser 502. During operation, gaseous refrigerant enters the condenser 502 through the micro compressor 501 to dissipate heat and liquefy, and then passes through the capillary tube 504 to reach the refrigeration copper tube 505. After evaporation, it carries away heat, achieving a cooling effect. Both the micro compressor 501 and the cooling fan 503 are connected to an external power source through wires passing through the outer shell 1 to ensure their normal operation. A partition 9 is provided between the inner shell 2 and the refrigeration device 5. The capillary tube 504 and the refrigeration copper tube 505 pass through the partition 9 and cooperate with the inner shell 2. The partition 9 separates the inner shell 2 from the refrigeration device 5 to prevent the cooling fan 503 from affecting the temperature inside the inner shell 2 when it is operating, and further ensures the temperature of the inner shell 2. The outer shell 1 is provided with an air inlet grille and an air outlet grille on the side wall corresponding to the partition 9. The air inlet grille and the air outlet grille can ensure the normal operation of the condenser 502 and the cooling fan 503. Moreover, the partition can play a certain role in heat preservation, which can further improve the efficiency of temperature change of the inner shell 2.

[0032] Cooling copper tubes 505 are evenly arranged on the outer surface of the inner shell 2. Cooling copper tubes 505 can also pass through the side wall of the inner shell 2 and be evenly arranged on the inner side wall of the inner shell 2. Cooling copper tubes 505 can reduce the temperature of the inner shell 2. The outer shell 1 is equipped with a temperature controller, which can monitor and control the temperature of the inner shell 2 to reach a constant temperature. Grooves are evenly arranged on the outer surface or inner side wall of the inner shell 2. Cooling copper tubes 505 are arranged inside the grooves. Cooling copper tubes 505 can better cooperate with the inner shell 2 and improve the cooling effect. Cooling copper tubes 505 and heating wires 401 are both cooperated with the inner shell 2 and are arranged alternately, but they will not affect each other when working. When the heating structure 4 is working, the cooling structure 5 is not working, and when the cooling structure 5 is working, the heating structure 4 is not working.

[0033] During testing, the operator can extend the base plate 7 from the inner shell 2 using the lifting structure 6, then clamp the button battery using the clamp 8, and finally retract the base plate 7. The device is then connected to the electrochemical workstation via a connecting cable. The cover plate 3 remains closed during the test. The operator can adjust the temperature using the cooling structure 5, the heating structure 4, and the temperature controller. The constant temperature device allows for testing of one battery at a time, covering any temperature range from -20°C to 60°C. It is compact, easy to operate, convenient to store, and provides constant temperature control.
