Description

Technical Field

[0001] The present application belongs to the field of electrode clamps, and more specifically, relates to a heat dissipation electrode clamp and an arc generating device. Background Art

[0002] The light source (i.e., excitation source) of an AC / DC direct-reading spectrometer generates light by exciting the sample with an arc generated by the upper and lower electrodes under the action of a high-voltage current. The stability of the light source is crucial for spectral analysis, directly affecting the precision and accuracy of the analytical method. The upper and lower electrodes must have excellent coaxiality, which requires two electrode clamps to clamp and support the upper and lower electrodes, respectively. Because the arc temperature during sample excitation can reach several thousand degrees Celsius, the electrode clamps can deform with increasing test frequency, affecting the coaxiality of the electrodes.

[0003] Existing electrode clamps primarily use liquid cooling to maintain temperature. While this method prevents deformation of the clamp due to excessive temperatures, it requires a separate coolant circulation system. Over time, this can lead to pipe aging, leakage, and coolant corrosion of the electrodes, necessitating maintenance. Furthermore, in addition to requiring regular coolant replacement, the cooling system must be drained during extended periods of downtime or when the machine is moved. This complex operation increases labor intensity and negatively impacts the diverse application scenarios of AC / DC direct-reading spectrometers. Utility Model Content
