Description

Technical Field

[0001] This utility model belongs to the field of mass spectrometry technology, specifically relating to a mass spectrometer with a heat dissipation structure. Background Technology

[0002] The light source of a mass spectrometer (such as an ion source or laser source) generates heat during operation. This is because the conversion of electrical or optical energy during the excitation of the sample or the generation of ions involves energy loss, with some energy released as heat. Excessive heat accumulation can affect the stability, accuracy, and even lifespan of the light source. Therefore, mass spectrometers are typically equipped with dedicated cooling systems (such as air cooling or water cooling) to control the temperature.

[0003] Existing heat dissipation structures for light sources typically involve installing a heat sink inside the mass spectrometer housing near the light source to accelerate airflow and achieve heat dissipation. However, this method is not very targeted. Since the heat generation points of the light source structure are relatively concentrated, if heat dissipation is carried out over a large area, it is impossible to efficiently dissipate heat in localized areas of the light source structure. The light source structure will generate high temperatures during operation, and if heat dissipation is not carried out in time, it will affect the lifespan of the light source and have an adverse impact on the detection results.

[0004] Therefore, a mass spectrometer with a heat dissipation structure was designed to overcome the aforementioned technical shortcomings. Utility Model Content

[0025] This specific embodiment is a mass spectrometer with a heat dissipation structure, and its structural schematic diagram is shown below. Figures 1-6 As shown, the mass spectrometer includes a main body 1, a mounting plate 2 is mounted on the rear side wall of the main body 1, and a light source structure 3 is mounted on one side wall of the mounting plate 2. The main body 1 of the mass spectrometer and its internal light source structure 3 are existing technologies and will not be described in detail in this solution. A copper tube 4 is provided on the outside of the light source structure 3. Several through holes 5 are opened on the side wall of the copper tube 4 near the light source structure 3. A fan 6 is installed on the side wall of the mounting plate 2 away from the light source structure 3. One end of the copper tube 4 passes through the mounting plate 2 and is connected to the air inlet of the fan 6.

[0026] For example, in a common inductively coupled plasma mass spectrometer (ICP-MS), the temperature in the plasma region can typically reach 6000-10000 K when the radio frequency light source is operating. In some mass spectrometers that use laser light sources, the local temperature generated when the laser interacts with the sample can also reach thousands of degrees Celsius.

[0027] A heat storage box 7 is fixedly connected to the side wall of the mounting plate 2. A guide pipe 8 is fixedly connected to the bottom surface of the heat storage box 7. The other end of the guide pipe 8 is connected to the air outlet of the fan 6. Several heat-receiving rods 11 are fixedly connected to the inner wall of the heat storage box 7. A heat recovery assembly is installed on the heat storage box 7.

[0028] The heating rod 11 can be made of the following materials:

[0029] Metallic materials: such as copper, aluminum, iron, etc. Metals have good thermal conductivity and can absorb and store a large amount of heat. Taking copper as an example, its specific heat capacity is relatively large. When absorbing the same amount of heat, its temperature rises relatively slowly, and when cooling down, it dissipates heat relatively slowly because it stores more heat.

[0030] Ceramic material: Ceramic has a high specific heat capacity and low thermal conductivity. This means that it can absorb more heat, and when dissipating heat, the low thermal conductivity results in a slow heat transfer rate, so the cooling time is relatively long.

[0031] Therefore, when the flow pipe 8 injects hot air into the heat storage box 7, the hot air will continuously heat the heating rod 11 so that the heat storage box 7 can maintain a high temperature.

[0032] like Figure 3 and Figure 5 As shown, the copper tube 4 has a spiral structure, and the light source structure 3 is located inside the copper tube 4. The spiral structure of the copper tube 4 increases the air intake range of the through-hole 5 for the light source structure 3, further increasing airflow and improving heat dissipation.

[0033] like Figure 4 and Figure 6 As shown, the top surface of the heat storage box 7 is equipped with a cover plate 9, and the top surface of the cover plate 9 is fixedly connected to an installation cylinder 10. A guide fan 12 is installed on the inner wall of the installation cylinder 10, and the top surface of the installation cylinder 10 is equipped with an end cover 13. Several connectors 14 are fixedly connected to the top surface of the end cover 13.

[0034] The heat within the heat storage box 7 can be distributed and transported through multiple connectors 14, facilitating heat transfer to appropriate locations, such as in the sample introduction system where samples enter the mass spectrometer via a transfer line. Heating the sample transfer line prevents sample condensation during transport, ensuring the sample enters the ion source accurately in gaseous form, thus improving analytical accuracy and repeatability. For example, when analyzing compounds with low volatility, the transfer line temperature is typically set between 150 and 300°C; heat recovery allows for preheating, effectively reducing equipment energy consumption.

[0035] like Figure 4 As shown, an insulation film 15 is fixedly connected to the inner wall of the heat storage box 7. By setting the insulation film 15, the heat preservation effect inside the heat storage box 7 can be increased and the heat loss can be reduced; and the insulation film 15 is an industrial insulation film 15, the material of which can be aluminum foil, rubber and plastic, aerogel, etc.

[0036] like Figure 3 As shown, a diversion pipe 16 is fixedly connected to the side wall of the copper pipe 4 near the fan 6 and the side wall of the guide pipe 8, respectively. A valve 17 is installed on the side wall of the diversion pipe 16.

[0037] Specifically, multiple shunt tubes 16 can be set. The upper shunt tube 16 can be connected to the copper tube 4 to facilitate heat dissipation of other heat-generating components inside the mass spectrometer body 1.

[0038] The lower shunt 16 can be connected to the external environment to quickly dissipate heat from the vicinity of the light source structure 3, thereby increasing the airflow around the light source structure 3 and improving the heat dissipation effect.

[0039] Working principle: When heat dissipation is required for the light source structure 3, the heat recovery is selected according to the needs. When heat recovery and reuse are required, the guide pipe 8 is connected to the heat storage box 7, and the fan 6 is started. The fan 6 draws the hot air around the light source structure 3 into the copper pipe 4 through the through hole 5. Some of the heat is conducted to the surface of the copper pipe 4. The hot air is introduced into the heat storage box 7 by the fan 6. The heat is absorbed by the heat-receiving rod 11 in the heat storage box 7. The external pipe is connected to one of the joints 14 for air circulation.

[0040] When heat recovery is not required, the lower shunt pipe 16 is connected to the outside of the mass spectrometer body 1, and the fan 6 is connected to the shunt pipe 16 through the valve 17. When the fan 6 draws in hot air, the hot air is directly discharged from the shunt pipe 16, thereby effectively improving the heat dissipation efficiency.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
