Embodiment Construction
[0013] Such as figure 1 As shown, the phase change device and the metal electrode are integrally formed, wherein the high-temperature terminal electrode 1 is connected to the device cover 3, and the metal low-temperature terminal electrode 5 is connected to the device cavity (cylinder). After the inner surface of the device is treated with heat conduction and insulation, the heat conduction frame is installed, the cover 3 is welded to the cavity, and only one feed port 2 is left for filling the phase change material. After filling the phase change material, the feed inlet 2 is sealed (screw package), so that the high-efficiency heat-absorbing phase change device 4 and the metal electrodes (1, 5) are integrally formed. The selection of materials for the phase change device ensures that the temperature of the phase change device is kept at 38°C to 40°C after absorbing heat, the working time of the device is within 30 minutes, and the temperature of the terminal part is always co...

The invention belongs to electrodes and particularly relates to an efficient thermal-insulation and phase-changing electrode. The efficient thermal-insulation and phase-changing electrode comprises a cylindrical barrel, wherein a cover is arranged at the top end of the barrel; a feeding opening and an air exhausting opening are formed in the top end of the cover; a high-temperature end electrode is further arranged at the top end of the cover; a low-temperature end electrode is arranged at the bottom end of the barrel; the barrel is internally provided with an efficient heat-absorption and phase-changing device. The efficient thermal-insulation and phase-changing electrode has the obvious beneficial effects that the phase-changing device and a metal electrode are integrally molded; the upper half part of the metal electrode is connected with the cover of the device and the lower half part of the metal electrode is connected with a cavity (barrel) of the device. After the inner surface of the device is subjected to heat-conduction insulation treatment, a heat-conduction framework is arranged and the cover and the cavity are welded and molded; only one feeding opening is formed for filling of a phase-changing material. After the phase-changing material is filled, the feeding opening is sealed (packaged by a thread) so as to realize the integrated molding of the phase-changing device and a copper electrode.
Description
technical field [0001] The invention belongs to electrodes, in particular to a high-efficiency heat-insulating phase-change electrode. Background technique [0002] According to the working environment of different applications and the condition that the ground can be reused for many times, the power supply battery used in various devices is a lithium battery. The battery is characterized by multiple charging and repeated use, but its normal operating temperature generally does not exceed 50 ℃, and the temperature of the working device powered by it can reach hundreds of degrees to several thousand degrees during the whole working process. During the working process, this high temperature will be conducted in a short time through the metal electrodes connected between the device and the battery To the end of the power supply battery, eventually causing the power supply battery to fail to work normally. In this context, the present invention proposes a design method to solve...
