Description

Technical Field

[0001] This utility model relates to the field of spectrometer technology, specifically to a rear chassis structure for a spectrometer. Background Technology

[0002] Spectrometers play a vital role in the testing industry. A benchtop spectrometer mainly consists of a front excitation stage and a rear chassis. The rear chassis houses the optical chamber, which occupies most of the space. Outside the optical chamber is a cover; one side of the cover houses the gas path and power supply, while the other side houses the mainboard, etc. Both sides generate heat, which is initially dissipated by a fan located at the front excitation stage blowing air onto the rear chassis. However, this method is ineffective, and the mainboard side suffers from interference and has messy wiring, making subsequent maintenance difficult. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides a rear chassis structure for a spectrometer, which effectively solves the problems of heat dissipation and interference, and the motherboard side is neatly arranged, facilitating subsequent maintenance.

[0004] The technical solution is as follows: a rear chassis structure for a spectrometer, comprising a spectrometer base, on which an optical chamber cover is mounted. A power supply and gas path device are mounted on the left outer wall of the optical chamber cover, and a main board and a control board are mounted on the right outer wall of the optical chamber cover. The optical chamber cover is characterized by having rear cooling fans mounted on both sides of its rear end, a shielding cover surrounding the main board and control board, and heat dissipation holes on the outside of the shielding cover. Cable grooves are provided above and on the front and rear sides of the main board and control board, and a through-hole is provided on the lower right side of the optical chamber cover.

[0005] By adopting this utility model, the addition of a rear cooling fan allows the heat generated by the power supply, motherboard, and control board to be better dissipated to the rear, reducing the temperature inside the rear chassis. Furthermore, the addition of a shielding cover increases the anti-interference capability of the motherboard and control board, improving the detection effect of the spectrometer. In addition, the structure on the right side of the optical chamber cover is rationally arranged so that power cables and other lines are inserted into the cable trays as close as possible, avoiding messy wiring and facilitating later inspection and maintenance.

[0007] See Figure 3 and Figure 4 As shown, a rear housing structure for a spectrometer includes a spectrometer base 1, a light chamber housing 2 mounted on the spectrometer base 1, a light chamber (not shown in the figure) installed inside the light chamber housing 2, and a large rear housing housing outside the light chamber housing 2, which is a common housing and has no modification compared with the prior art.

[0008] The power supply 3 and the air passage device 4 are installed on the left outer wall of the optical chamber housing 2. The main board 5 and the control board 6 are installed on the right outer wall of the optical chamber housing 2. The main board is used to collect optical signals and convert them into digital signals. The control board is used to control temperature heating, excitation flow switch, vacuum, etc. Rear cooling fans 7 are installed on both sides of the rear end of the optical chamber housing 2. Together with the front fan at the front excitation stage device, they can better remove heat. The main board 5 and the control board 6 are covered with a shielding cover 8. The shielding cover 8 is provided with heat dissipation holes 9. The shielding cover 8 is used to increase the anti-interference ability without affecting the heat dissipation effect.

[0009] Cable trays 10 are provided on the top and front and rear ends of the main board 5 and control board 6. A through-hole 11 is provided on the lower right side of the optical chamber housing 2, allowing power cables from the front laser stage to pass directly into the cable trays without needing to be threaded through the optical chamber housing. The wiring sides of the main board 5 and control board 6 are oriented towards and close to the cable trays to ensure smooth cable insertion and avoid clutter. The through-hole 11 is located at the bottom and is used for connecting the control board to the optical chamber and for the exit of power cables from the optical chamber. The overall layout is neat and tidy. Figure 6 As shown, the shielding cover has been omitted for clarity. It should be noted that in the actual product, the vacuum control section is presented as a separate small circuit board, distinct from the control board. However, the wiring side is still positioned as close as possible to the wire channel, maintaining an overall appearance similar to... Figure 2 Compared to other materials, it is cleaner and easier to inspect and maintain.
