Description

Technical Field

[0001] The utility model belongs to the technical field of tritium lamp heat dissipation, and specifically relates to a heat dissipation mechanism for a tritium lamp. Background Technique

[0002] Deuterium lamps are widely used in various analytical and testing instruments such as ultraviolet detectors of liquid chromatographs and UV-VIS spectrophotometers. The continuous spectrum emitted by deuterium lamps ranges from 180nm in the ultraviolet band to 700nm in the visible light band. It mainly relies on plasma discharge, which means keeping the deuterium lamp in a stable deuterium element arc state all the time, making the deuterium lamp a light source for high-precision analytical measurement instruments. Different wavelengths can be obtained through the adjustment of the grating. Noise and drift are two important parameter indicators for measuring the performance of ultraviolet detectors. After the deuterium lamp is lit, it needs to dissipate the maximum energy. How to ensure heat dissipation is the primary consideration for ultraviolet detectors.

[0003] According to the patent with the patent number CN215808374U, a tritium lamp heat dissipation device is disclosed, including a box body. A box cover is fixedly connected to the top of the box body. An adjusting plate is provided on the top of the box cover. A tritium lamp passing through the box cover is fixedly connected to the bottom of the adjusting plate. The adjusting plate is provided with adjusting bolts for adjusting the horizontal and vertical positions of the tritium lamp to adjust the position of the light-emitting window of the tritium lamp to be at the same horizontal position as the central hole of the box body. Rounded heat dissipation fins and a heat dissipation fan are evenly distributed on the outer side of the box body. In the utility model, through the combined use of the heat dissipation fan and the rounded heat dissipation fins, the structure is simple, the heat dissipation performance of the device is improved, and the best heat dissipation effect is achieved, thereby avoiding the problem of affecting the accuracy of experimental data and results due to untimely heat dissipation.

[0004] Although the above-disclosed device can dissipate heat from the device through the combined use of a heat dissipation fan and rounded heat dissipation fins, due to the poor air circulation inside the box body and the sealed state of the box body and the box cover, it is difficult to quickly discharge the heat inside the box body, which is not conducive to the heat dissipation fan to dissipate heat from the tritium lamp. Therefore, we provide a heat dissipation mechanism for a tritium lamp to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 7 shown, the present utility model provides a heat dissipation mechanism for a tritium lamp, including a box body 1. A bottom inside the box body 1 is fixedly connected with an exhaust frame 14. An inner wall of the exhaust frame 14 is provided with ventilation holes 13. A middle part of the exhaust frame 14 is circular. An inner wall of the ventilation hole 13 is inclined, so that after the wind enters the exhaust frame 14, it can blow obliquely upward, thereby cooling the tritium lamp 4 inside the box body 1. A surface of the box body 1 is provided with an air inlet duct 9. One end of the air inlet duct 9 penetrates through the box body 1 and is connected to the inside of the exhaust frame 14. The other end of the air inlet duct 9 is provided with a fan 8. A top end of the box body 1 is detachably connected with a mounting plate 3. A middle part of the mounting plate 3 is provided with a tritium lamp 4 extending into the box body 1. The mounting plate 3 is communicated with a ventilation cylinder 5. The tritium lamp 4 is located in a middle part of the ventilation cylinder 5. A top end of the ventilation cylinder 5 is provided with a plurality of through holes 6. With the above-described structure, the fan 8 can be used to convey the wind through the air inlet duct 9 into the exhaust frame 14, and then blow out through the ventilation holes 13, so as to achieve heat dissipation treatment for the tritium lamp 4. Then the wind will continue to flow into the ventilation cylinder 5 and finally be discharged through the through holes 6, thereby ensuring air circulation inside the box body 1 and improving the heat dissipation effect. Mechanical parts and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts a conventional connection method in the prior art, which will not be elaborated here.

[0024] AsFigure 1 , Figure 2 and Figure 5 As shown in Figure 1 , Figure 2 , and Figure 5 , several exhaust pipes 7 are connected to the inner wall of the ventilation pipe 5, and the exhaust pipes 7 are arc-shaped. With the arrangement of the exhaust pipes 7, the wind can be blown from the bottom of the box body 1 through the exhaust pipes 7 to the top of the tritium lamp 4. Finally, the wind entering the exhaust pipes 7 will blow to the top of the tritium lamp 4 for heat dissipation.

[0025] As Figure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 , and Figure 3 , several fins 2 are fixedly connected to the surface of the box body 1, and the fins 2 are U-shaped. With the arrangement of the fins 2, the heat in the box body 1 can be dissipated.

[0026] As Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , an air outlet pipe 12 is connected to the side surface of the fan 8 away from the air inlet. The air outlet pipe 12 is inserted into the air inlet pipe 9, which is convenient for personnel to quickly connect the fan 8 with the air inlet pipe 9, so as to blow the wind into the exhaust frame 14 and ensure the air circulation in the box body 1.

[0027] As Figure 3 , Figure 4 and Figure 5 As shown in Figure 3 , Figure 4 , and Figure 5 , several sealing strips 11 are sleeved on the surface of the air outlet pipe 12, and several sealing grooves 10 are formed on the inner wall of the air inlet pipe 9. The sealing strips 11 are clamped into the corresponding sealing grooves 10. With the above structure, the fan 8 can be quickly connected to the air inlet pipe 9. Just insert the fan 8 into the air inlet pipe 9 through the air outlet pipe 12. At the same time, the sealing strips 11 will also be inserted into the corresponding sealing grooves 10, so as to ensure the connection tightness of the air outlet pipe 12 and the air inlet pipe 9 and prevent the air outlet pipe 12 from easily separating from the air inlet pipe 9.

[0028] As Figure 1 , Figure 2 and Figure 7 As shown in Figure 1 , Figure 2 , and Figure 7 , mounting holes 15 are provided at the four corners of the top of the box body 1, and the four corners of the surface of the mounting plate 3 are installed in the corresponding mounting holes 15 by screws, which is convenient for installing the mounting plate 3 on the box body 1.

Then the wind will continue to flow into the ventilation pipe 5 and finally be discharged through the through holes 6 and the exhaust pipes 7, thus ensuring the air circulation in the box body 1, improving the heat dissipation effect, and at the same time being able to cool the top of the tritium lamp 4. Moreover, the fan 8 has the characteristics of being easy to install, and can be replaced, maintained, and cleaned subsequently.
