Description

Technical Field

[0001] The invention relates to the technical field of spectrometers, and in particular to a built-in micro cooling system for a spectrometer. Background Art

[0002] Inductively coupled plasma atomic emission spectrometer (ICP) is abbreviated as ICP. It generates plasma flame through the action of power module, coil module and other modules. The sample enters the plasma after atomization. Various elements in the sample are excited to produce characteristic spectra under the action of plasma. By detecting the wavelength and intensity of these characteristic spectra, various elements can be qualitatively or quantitatively analyzed. In the process of generating and maintaining plasma, the devices of the power module and coil module will generate a lot of heat. If the device is overheated, it will not work properly. In order to ensure that it can work properly, it must be cooled. Conventional air cooling cannot meet the requirements of rapid cooling due to its low cooling efficiency, and it is easy to cause instrument failure due to overheating; conventional water cooling usually requires an external cooling water machine, which is bulky and will occupy limited laboratory resources. It is also separated from the instrument and cannot work in coordination. The cooling efficiency is uncontrollable and it is very inconvenient to use; the use of a chiller also requires frequent replacement of cooling water, which is time-consuming and labor-intensive, affecting the overall experimental efficiency.

[0018] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings of the embodiments of the present invention, and the present invention is not limited to the following specific implementation methods. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0019] like Figure 1 to Figure 2 As shown, a built-in micro cooling system for a spectrometer includes: a compressor 100, a radiator 200, a throttling mechanism 300, a cooling mechanism, a pump body 500, a power module 600, a coil module 700 and a control system 800; the compressor 100 is connected to the radiator 200, the radiator 200 is connected to the cooling mechanism through the throttling mechanism 300, the output end of the power module 600 and the output end of the coil module 700 are both connected to the cooling mechanism, the cooling mechanism is respectively connected to the input end of the power module 600 and the input end of the coil module 700 through the pump body 500, and the cooling mechanism is connected to the compressor 100; the compressor 100, the radiator 200 and the pump body 500 are all electrically connected to the control system 800.

[0020] Further, the throttling mechanism 300 is a capillary tube. The throttling mechanism 300 is an electronic expansion valve. The cooling mechanism includes a coolant tank 410 and a condenser 420. The condenser 420 is arranged in the coolant tank 410. One end of the condenser 420 is connected to the throttling mechanism 300, and the other end is connected to the compressor 100. The coolant tank 410 is used to hold coolant. The coolant tank 410 is connected to the power module 600 and the coil module 700 respectively through the pump body 500. The pump body 500 is a micro pump. The coolant is an antifreeze liquid.

[0021] In the above embodiment, the built-in micro cooling system of the spectrometer further includes a connecting mechanism, through which the pump body 500 is respectively connected to the power module 600 and the coil module 700. The connecting mechanism includes two three-way connectors 910, and the power module 600 and the coil module 700 are both provided with connecting pipes 920, the pump body 500 is respectively connected to the connecting pipe 920 on the power module 600 and the connecting pipe 920 on the coil module 700 through one of the three-way connectors 910, and the connecting pipe 920 on the power module 600 and the connecting pipe 920 on the coil module 700 are connected to the coolant tank 410 through another three-way connector 910.

[0022] That is to say, by setting up a built-in micro cooling circulation system, the cooling problem of the instrument can be effectively solved. The gaseous refrigerant is compressed into a high-temperature and high-pressure gas by the compressor 100, and then the high-temperature and high-pressure gas passes through the radiator 200, releases the latent heat of condensation and becomes a high-temperature medium-pressure liquid, and then flows through the throttling mechanism 300 to become a low-temperature and low-pressure liquid. Then, when flowing through the condenser, a large amount of external heat is absorbed and vaporized into saturated steam, thereby realizing external medium refrigeration, and the steam is compressed by the compressor 100 to realize the cooling cycle. Further, the cooling liquid cooled by the cooling system is transported to the power module 600 and the coil module 700 by a micro pump, and the hot water is transported back to the cooling water tank after the heat exchange is completed to continue to be cooled by the cooling circulation system. Through continuous circulation, the working state of the compressor 100 and other corresponding components is controlled in real time by the control system 800 according to the working state of the instrument and the cooling water temperature, so that the efficiency of the cooling water circulation system is maximized and the energy consumption of the whole is optimized, which can ensure that all modules of the instrument work without overheating, thereby ensuring the smooth progress of the detection process.

[0023] That is to say, the built-in micro cooling system of the spectrometer is small in size and can be directly built into the instrument, so that the instrument does not need any external cooling equipment, and the control system 800 of the entire cooling circulation system can be coordinated with the instrument to achieve maximum cooling efficiency and energy consumption. The entire cooling system and circulation system are completely sealed, and no external impurities enter to affect the refrigeration efficiency. Therefore, when in use, no maintenance is required, and by using antifreeze as the coolant, the problem of ice formation caused by the use of cooling water is avoided.

[0024] In summary, the above-mentioned embodiments are not limitative embodiments of the present invention, and any modifications or equivalent variations made by those skilled in the art on the basis of the essential contents of the present invention are within the technical scope of the present invention.
