Description

Technical Field

[0001] The invention relates to the technical field of fluorescence spectrometers, in particular to a fluorescence spectrometer with a heat dissipation structure. Background Art

[0002] Fluorescence spectrometer, also known as fluorescence spectrophotometer, is an instrument for qualitative and quantitative analysis. Through the detection of fluorescence spectrometer, the excitation spectrum, emission spectrum, quantum yield, fluorescence intensity, fluorescence lifetime, Stokes shift, fluorescence polarization and depolarization characteristics, and fluorescence quenching information of the substance can be obtained. The analysis object is suitable for samples in industries such as steelmaking, non-ferrous metals, ceramics, petroleum, and glass.

[0003] According to a Chinese patent with the announcement number "CN210775288U", an X-ray fluorescence spectrometer is disclosed, which includes a spectrometer body and a cooling fan. A built-in component area is provided at the lower end of the spectrometer body, and four groups of cooling fans are installed on the inner wall of the left end of the built-in component area by screws. An air outlet is provided on the lower right side of the spectrometer body. A cover is hinged at the upper end of the spectrometer body, and the cover is provided at the upper end of the working area. The working area is provided on the upper side of the spectrometer body. A knob is inserted at the lower front side of the cover, and an insert is welded at the back end of the knob. The insert is embedded in the lower front side of the spectrometer body. The utility model sets two groups of clamps, so that if a partially rounded object cannot be directly placed in the working area for detection, the two groups of clamps can be used to limit and fix the object, so that the object can remain in a fixed state, thereby preventing the object from shaking and causing poor detection effect. When an existing fluorescence spectrometer is in use, the internal laser light source and internal electronic components will generate a lot of heat, which is generally dissipated by a cooling fan. However, when a single cooling fan is used to dissipate heat for electronic components, its heat dissipation efficiency is low, resulting in the inability to quickly dissipate the heat inside the device. Therefore, a fluorescence spectrometer with a heat dissipation structure is proposed to solve the above-mentioned problem. Summary of the invention
