Detailed Implementation

[0024] The present invention will be described in detail below with reference to specific embodiments.

[0025] This utility model relates to a cooling installation structure for an in-situ laser gas analyzer. It primarily addresses the problem that the meter head structure of an in-situ laser gas analyzer, which includes a meter head containing numerous electrical components and a channel support structure for observation, cannot effectively dissipate heat in high-temperature environments. This leads to excessively high internal temperatures, damage to electrical components and the meter head structure, or distortion of measurement data. By configuring a dedicated meter head cooling and heat dissipation structure, the installation structure ensures that the meter head of the in-situ laser gas analyzer can continue to operate and maintain its measurement validity even in high-temperature environments exceeding its maximum operating temperature.

[0026] like Figure 1 , Figure 2 As shown, the installation structure mainly includes an in-situ laser gas analyzer head 1, a cooling chamber 2, a gas source input pipe 3, a vortex tube 4, and a gas output pipe 5;

[0027] The in-situ laser gas analyzer head 1 is the main structure on the analyzer that requires isolation and protection. The cooling chamber is used to create an independent and enclosed heat dissipation space for the in-situ laser gas analyzer head 1, isolate the in-situ laser gas analyzer head 1 from the external high-temperature environment, and assist in the installation and positioning of power cables and data cables. The gas source input pipe 3 is connected to an external high-pressure gas source. The high-pressure gas inside the high-pressure gas source is split into low-temperature gas and high-temperature gas after passing through the vortex tube 4. The low-temperature gas is introduced into the cooling chamber to dissipate heat from the in-situ laser gas analyzer head 1, and finally discharged through the gas output pipe.

[0028] like Figure 3 , Figure 4 As shown, the cooling chamber 2 is a shell structure, with power cord connection holes and signal line connection holes on its left and right sides, respectively. A meter outlet hole 2c is provided on the back, and an observation window 2d is provided on the front. A transparent observation plate 6 is embedded in the observation window 2d. An air inlet and an air outlet are provided on the left and right sides of the bottom of the cooling chamber 2, respectively.

[0029] The in-situ laser gas analyzer head 1 is located in the middle of the cooling chamber 2. The power line and signal line pass through the power line connection hole and signal line connection hole on the left and right sides respectively and are connected to the in-situ laser gas analyzer head 1.

[0030] The gas source input pipe 3 is connected to the high-pressure gas inlet of the vortex tube 4, the cold gas output pipe of the vortex tube 4 is connected to the air inlet, and the gas output pipe 5 is connected to the air outlet.

[0031] Specifically, to facilitate installation and ensure the isolation of the internal and external environments of the cooling chamber 2, in this embodiment, positioning nuts 7 and sealing rings are respectively fitted onto the power line and signal line to ensure a sealed connection between the power line and signal line and the power line connection hole and the signal line connection hole.

[0032] As a preferred embodiment, to facilitate the assembly and use of the meter head, in this embodiment, the cooling chamber 2 is composed of a front positioning shell 20 and an upper positioning shell 21 and a lower positioning shell 22 located on the rear side of the front positioning shell 20;

[0033] The front positioning shell 20 is a box structure with a rear opening and an observation window 2d on the front; the upper positioning shell 21 and the lower positioning shell 22 are formed by dividing the box with a front opening; the dividing surfaces of the upper positioning shell 21 and the lower positioning shell 22, as well as the connecting surfaces of the upper positioning shell 21 and the lower positioning shell 22 and the front positioning shell 20, are respectively provided with connecting plate surfaces 23, and shell connecting holes 2g are evenly provided on the connecting plate surfaces 23.

[0034] Preferably, the power cord connection hole and the signal cord connection hole are respectively located on the left and right side shell surfaces of the lower positioning shell 22, and the air inlet and air outlet are located on the bottom shell surface of the lower positioning shell 22.

[0035] The front positioning shell 20, the upper positioning shell 21, and the lower positioning shell 22 are fixedly connected by bolts and nuts provided in the shell connection hole 2g.

[0036] To improve the effective utilization of cooling capacity and prevent cooling loss, sealing gaskets are installed between the interconnected connecting plates 23.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model.
