Inner heat dissipation device of spectrometer

Abstract

The invention relates to the field of inner heat dissipation of a spectrometer, in particular to an inner heat dissipation device of a spectrometer. The inner heat dissipation device is capable of conveniently achieving a heat dissipation effect, simple in structure and low in cost, comprises an electronic device installation plate and is characterized in that a heat dissipation base is installed on one side of the electronic device installation plate; support seats are installed on two ends of the heat dissipation base; rotating wheel devices are arranged on the two support seats through a rotation shaft; one end of the rotation shaft is connected with a driving motor; each rotating wheel device comprises discs on two sides and multiple long strip-shaped blades installed on the discs; the long strip-shaped blades are uniformly distributed along the circumferential directions of the discs; the cross section of each long strip-shaped blade is arc-shaped; and the length of each long strip-shaped blade corresponds to the size of the electronic device installation plate.

Description

technical field [0001] The invention relates to the technical field of heat dissipation inside a spectrometer, in particular to a heat dissipation device inside a spectrometer. Background technique [0002] The direct-reading spectrometer is a device that measures the intensity of different wavelength positions of the spectral line with a photodetector such as a photomultiplier tube. The electromagnetic radiation of the radiation source is separated into the required wavelength or wavelength region by a dispersive element, and at the selected wavelength (or scanning A certain band) for intensity measurement, due to the large number of internal electronic devices and relatively dense distribution, more heat will be generated when working for a long time, if the heat is not dissipated, it will affect the normal operation of the instrument, and the existing heat dissipation methods are generally The use of cooling fans can achieve a better cooling effect, but the electronic dev...

[0002] The direct-reading spectrometer is a device that measures the intensity of different wavelength positions of the spectral line with a photodetector such as a photomultiplier tube. The electromagnetic radiation of the radiation source is separated into the required wavelength or wavelength region by a dispersive element, and at the selected wavelength (or scanning A certain band) for intensity measurement, due to the large number of internal electronic devices and relatively dense distribution, more heat will be generated when working for a long time, if the heat is not dissipated, it will affect the normal operation of the instrument, and the existing heat dissipation methods are generally The use of cooling fans can achieve a better cooling effect, but the electronic devices in the direct reading spectrometer are arranged in a flat and long rectangular area. In order to ensure the cooling effect, a row of cooling fans that are highly compatible with the rectangular area need to be arranged so The internal structure becomes complicated, and the working cost of multiple cooling fans is relatively high
