This invention discloses an insulating encapsulation structure and connection method for a probe temperature sensor, relating to the field of temperature sensor technology. The insulating connection bracket has an outer insulating and thermally conductive protective layer, and contains insulating adhesive and a temperature-sensing component. The specific implementation is as follows: an insulating layer assembly, a built-in snap-fit ​​structure within the insulating connection bracket, and an eccentric cavity for housing the temperature-sensing component. A thermistor glass body is used as the insulator. In the insulation process, direct contact between the glass body and the inner wall of the bracket reduces one useless insulating layer. The cavity formed by the end of the insulating connection bracket and the insulating layer assembly houses the temperature-sensing component. The cavity contains a clearance structure for the thermistor pins and multiple layers of insulation between the pins and the conductive copper wires. A fluid insulating adhesive is used, and then the insulating connection is cured. Finally, the encapsulation is placed inside a metal shell containing insulating adhesive and cured, thus forming multiple layers of effective insulation and sufficient safe insulation thickness between the thermistor conductive pins and the metal shell.

The electrochemical lithium extraction combined with chemical reduction leaching of nickel, cobalt, and manganese using this composite electrode not only achieves high-efficiency recovery of valuable metals such as lithium, nickel, cobalt, and manganese, but also significantly reduces wastewater treatment costs and environmental risks.

This invention provides a CAN converter with a heat dissipation structure, including a CAN converter body and a heat dissipation shell on the outside of the CAN converter body. A heat dissipation cavity is formed between the heat dissipation shell and the CAN converter body. Support legs are installed at the four corners of the bottom side of the heat dissipation shell. The heat dissipation shell includes an inner thermally conductive layer and an outer heat dissipation fin layer. This invention is reasonably designed. By setting up a heat dissipation shell, the thermally conductive layer quickly conducts heat, the heat dissipation fin layer increases the heat dissipation area, and a cooling fan forms forced convection cooling. The combination of multiple heat dissipation methods significantly improves the heat dissipation efficiency of the CAN converter body, enabling it to quickly and effectively dissipate the heat generated by the CAN converter body and reduce the operating temperature of the device. The addition of a thermally conductive silicone pad reduces the thermal resistance between the CAN converter body and the heat dissipation shell, further improving the heat conduction effect and ensuring that heat is transferred to the heat dissipation shell for dissipation in a timely manner.

This invention discloses a method for preparing a non-fluorinated composite proton exchange membrane. The method uses sulfonated polyether ether ketone (PEEK) as the matrix and incorporates two specific sulfonated covalent organic framework materials. The addition of the sulfonated covalent organic framework forms a continuous hydrogen bond network and highly efficient proton transport channels within the membrane, significantly improving proton conductivity. The composite membrane achieves a proton conductivity of up to 0.41 S / cm at 80°C, approximately three times higher than the unmodified matrix. Simultaneously, the rigid structure of the covalent organic framework effectively enhances the membrane's mechanical strength, increasing its tensile strength to 75 MPa, achieving a synergistic enhancement of proton conductivity and mechanical properties. The non-fluorinated composite proton exchange membrane prepared by this invention exhibits a stable composite membrane structure and excellent overall performance, making it suitable for applications such as proton exchange membrane water electrolysis for hydrogen production.
