Description

Technical Field

[0001] The utility model relates to the application field of ICP spectrum analysis technology, in particular to a miniaturized high-efficiency refrigeration device for a glass cyclonic mist chamber of an ICP spectrum analyzer. Background Art

[0002] In the field of inductively coupled plasma spectrometry, the analysis and injection of organic samples sometimes require cryogenic conditions to ensure the accuracy and reliability of the analytical results. A glass cyclonic spray chamber is a key piece of equipment in this process, responsible for separating large droplets from aerosols and thus ensuring the stability of analytical results. The glass cyclonic spray chamber also serves as the final sample injection process before combustion. When cryogenic injection is required at temperatures between -5°C and -15°C, the glass cyclonic spray chamber must be rapidly cooled.

[0003] Existing solutions typically rely on large refrigeration equipment, such as compressor-type chillers, to maintain a low temperature in the glass cyclonic spray chamber. These devices are typically bulky, energy-intensive, and noisy during operation. Furthermore, due to their relatively low cooling efficiency, they often take a long time to reach the required low temperature.

[0004] The problems existing in the prior art in this field are mainly as follows:

[0005] First, the existing refrigeration equipment is large in size and takes up a lot of space, which is not conducive to the laboratory's space layout and equipment management.

[0006] Secondly, these devices have high energy consumption, which increases the cost of the experiment.

[0007] Thirdly, the existing equipment will generate a lot of noise during operation, affecting the working environment of the laboratory.

[0008] Finally, the refrigeration efficiency of existing equipment is relatively low and cannot quickly reach the required low temperature state, which may affect the accuracy and reliability of the analysis results.

[0009] Therefore, there is an urgent need to provide a miniaturized and efficient refrigeration device for the glass cyclonic spray chamber of an ICP spectrometer. Utility Model Content

[0010] To solve the above technical problems, the utility model provides a miniaturized and efficient refrigeration device for the glass cyclonic mist chamber of an ICP spectrometer. It adopts a semiconductor refrigeration chip as the cooling source. Compared with traditional compressor-type refrigerators, it is smaller in size and occupies less space, which is beneficial to the space layout and equipment management of the laboratory.

[0011] The technical solution of the utility model is: a miniaturized and efficient refrigeration device for a glass cyclonic mist chamber of an ICP spectrometer, comprising a box body having a supporting area for placing a cyclonic mist chamber vessel and a refrigeration area for dissipating heat from the supporting area;

[0012] The supporting area includes a mist chamber support, an upper end of the mist chamber support is provided with an opening for placing the vessel, and a side of the mist chamber support close to the refrigeration area is a vertical surface structure;

[0013] The refrigeration zone has a semiconductor refrigeration plate used in conjunction with the vertical surface, and the semiconductor refrigeration plate is connected to a radiator;

[0014] It also includes a control board connected to the semiconductor refrigeration plate.

[0015] Furthermore, the box body is provided with a bottom plate, and the mist chamber support is connected to the bottom plate via a receiving block.

[0016] Furthermore, the inner cavity of the spray chamber holder is a shape structure that cooperates with the vessel, and the bottom of the spray chamber holder is provided with a through hole, the bottom plate and the receiving block are provided with a through groove that cooperates with the through hole, and one end of the vessel passes through the through hole and extends out of the spray chamber holder.

[0017] Furthermore, the mist chamber support is wrapped with thermal insulation cotton on all sides.

[0018] Furthermore, the supporting area is provided with a heat-insulating cover plate used in conjunction with the mist chamber support.

[0019] Furthermore, a heat-conducting layer is provided between the vertical surface of the mist chamber support and the semiconductor refrigeration plate.

[0020] Furthermore, the heat-conducting layer is a thermal grease layer, and the thickness of the thermal grease layer is 0.01 mm.

[0021] Furthermore, the radiator is composed of heat pipes and fins, and the fins are provided in two groups.

[0024] The beneficial technical effects of the utility model are:

[0025] 1. This utility model features an aluminum support that encases the glass cyclonic mist chamber. One side of the support features a vertical surface that aligns with the cooling surface of a semiconductor cooling element.

The temperature is controlled and monitored in real time by the control panel, enabling the target temperature to be quickly reached and maintained. This design enables precise temperature control of the equipment, thereby ensuring the accuracy and reliability of the analysis results.

[0029] 5. The spray chamber is wrapped with insulation cotton to isolate the outside temperature. This design can effectively prevent the influence of external heat on the equipment, thereby improving the stability and reliability of the equipment.

[0030] 6. Through the heat insulation treatment of heat pipes, fins, fans and thermal insulation cotton, the temperature of the fog chamber can be reduced to -20 degrees Celsius within 30 minutes, which can meet the needs of various scene tests.

[0042] like Figure 1-Figure 5 As shown, the present invention specifically relates to a miniaturized and efficient refrigeration device for a glass cyclonic spray chamber of an ICP spectrometer, comprising a housing 100 having a supporting area 110 for placing a cyclonic spray chamber vessel 200 and a refrigeration area 120 for dissipating heat from the supporting area 110;

[0043] The supporting area 110 includes a mist chamber support 112. The upper end of the mist chamber support 112 is provided with an opening for placing the vessel 200. The side of the mist chamber support 112 close to the refrigeration area 120 is a vertical surface 1121 structure.

[0044] The refrigeration zone 120 has a semiconductor refrigeration plate 124 used in conjunction with the vertical surface 1121, and the semiconductor refrigeration plate 124 is connected to a radiator;

[0045] The device further includes a control board 400 connected to the semiconductor cooling plate 124 .

[0046] It should be noted that the box body 100 is a whole, and is divided into a supporting area 110 for placing the container 200 and a refrigeration area 120 for dissipating heat from the supporting area 110 according to different functions.

[0047] Vessel 200 is responsible for atomizing the sample and interacting with the plasma to generate a spectral signal for analysis. In ICP analysis, some solutions require analysis at -5°C to -15°C, while the instrument operates at room temperature, so the glass cyclonic spray chamber must be rapidly cooled.

[0048] The interior of the mist chamber support 112 is shaped to fit the container 200, thereby securing the container 200. Furthermore, the mist chamber support 112 is made of aluminum. One side of the mist chamber support 112 has a vertical surface 1121. This vertical surface 1121 engages one end of a semiconductor cooling fin 124, which in turn engages a heat sink. The heat sink comprises a heat pipe 121 connected to the semiconductor cooling fin 124 and fins 122 connected to the heat pipe 121.

[0049] The semiconductor cooling plate 124 is activated by the control board 400 to absorb the temperature of the mist chamber support 112 and dissipate the absorbed temperature through the heat pipe 121 and the fins 122 , thereby achieving the purpose of cooling the mist chamber support 112 .

[0050] The box body 100 is provided with a bottom plate 130 , and the mist chamber support 112 is connected to the bottom plate 130 via a receiving block 111 .

[0051] Among them, the receiving block 111 is connected to the bottom plate 130 by bolts, the upper end surface of the receiving block 111 is provided with a positioning hole, and the bottom of the spray chamber support 112 is provided with a positioning groove, which is connected to the positioning groove through the positioning hole to fix the position of the spray chamber support 112, thereby ensuring the stability of the spray chamber support 112.

[0052] The inner cavity of the spray chamber holder 112 is shaped to accommodate the container 200. A through hole is provided at the bottom of the holder 112, and a through slot is provided on the bottom plate 130 and the receiving block 111 to accommodate the through hole. One end of the container 200 passes through the through hole and extends out of the spray chamber holder 112. This ensures the stability of the container 200 while facilitating connection of one end of the container 200 to external equipment.

[0053] The spray chamber support 112 is wrapped with insulation cotton 300 on all sides, which completely covers the spray chamber support 112 to isolate the external temperature. This design can effectively prevent the influence of external heat on the device, thereby improving the stability and reliability of the device.

[0054] The supporting area 110 is provided with a heat-insulating cover plate (not shown) used in conjunction with the spray chamber support 112 , which not only ensures the stability of the vessel 200 in the spray chamber support 112 but also isolates the vessel 200 from the external temperature.

[0055] A heat-conducting layer (not shown in the figure) is provided between the vertical surface 1121 of the mist chamber support 112 and the semiconductor cooling plate 124 to improve heat dissipation efficiency.

[0056] Furthermore, the heat-conducting layer is a thermal grease layer, and the thickness of the thermal grease layer is 0.01 mm.

[0057] The radiator is composed of a heat pipe 121 and fins 122, and the fins 122 are provided with two groups. One end of the heat pipe 121 is connected to the semiconductor refrigeration sheet 124, and the other end of the heat pipe 121 is connected to the fins 122, which improves the heat dissipation efficiency. Combined with the insulation treatment of the mist chamber support 112 by the thermal insulation cotton 300, the ambient temperature of the mist chamber support 112 can be reduced to minus 20 degrees.

[0058] The box body 100 is provided with a heat dissipation fan 123 , and the side wall of the box body 100 is provided with heat dissipation holes used in conjunction with the heat dissipation fan 123 .

[0059] The spray chamber holder 112 is equipped with a platinum resistor (not shown) connected to the control board 400. The resistance value is mapped to the temperature value. The circuit board controls and monitors the temperature in real time, enabling the target temperature to be quickly reached and maintained. This design enables precise temperature control of the device, thereby ensuring the accuracy and reliability of the analysis results.

The protection scope of the present invention is not limited thereto.
