Description

Technical Field

[0001] This application belongs to the technical field of gas chromatographs, and particularly relates to an air-cooling mechanism for a gas chromatograph. Background Art

[0002] Gas chromatographs are widely used in fields such as chemistry, environmental science, and food safety, and can efficiently and rapidly analyze compounds. During the use of a gas chromatograph, the components inside its chassis generate heat. Conventional heat dissipation means mostly use fan heat dissipation or heat dissipation holes, and their heat dissipation performance is not good. For this reason, Chinese Patent No. 202222145660.1 discloses an air-cooling structure for a gas chromatograph. The outside air is introduced into the gas chromatograph frame through a radiator fan, so that the air passes through the temperature control detection and recording system and enters other parts of the gas chromatograph through the ventilation holes, and the heat generated by the gas path system, injection system, and detection system is taken away by the air circulation and discharged from the ventilation holes on the gas chromatograph frame, thus forming a ventilation system. Although the inside of the gas chromatograph can be cooled in this application, as the use time of the gas chromatograph increases, the temperature inside the machine will gradually rise, and the heat dissipation area of the above ventilation system is fixed, resulting in poor heat dissipation effect.

[0009] Further, the adjusting component includes a ring seat disposed inside the box body. The mounting rod is parallelly mounted at one end of the ring seat facing the first heat conduction component. One end of the ring seat away from the first heat conduction component is provided with an adjusting rod. The adjusting rod extends out of the side wall for mounting the blower, and the adjusting rod is movably connected to the side wall.

[0010] Further, one end of the ring seat close to the first heat conduction component gradually contracts towards one end of the ring seat close to the blower.

[0011] Further, a wind guiding member sleeving the outside of the blower is provided on the side wall; the wind guiding member is cylindrical, and one end of the wind guiding member close to the first heat conduction component gradually contracts towards one end of the wind guiding member close to the blower.

[0012] Further, when the ring seat drives the second heat dissipation fins to be inserted into the slot under the drive of the adjusting rod, an air guiding surface for transferring the heat inside the box body towards the blower direction is formed between the ring seat and the inner end surface of the wind guiding member.

[0030] In the above, refer to Figures 2 - 3 As shown, a wind guiding member 9 sleeved outside the fan 8 is provided on the side wall 6; the wind guiding member 9 is in a cylindrical shape, and one end of the wind guiding member 9 close to the first heat conduction component 3 gradually contracts towards one end of the wind guiding member 9 close to the fan 8.

[0031] In the above, refer to Figures 2 - 4 As shown, when the ring seat 41 drives the second heat dissipation fins 52 to be inserted into the slots 33 under the drive of the adjusting rod 42, an air guiding surface 10 for transferring the heat inside the box body 1 towards the fan 8 is formed between the ring seat 41 and the inner end surface of the air guiding member 9, and the air guiding area of the formed air guiding surface 10 gradually contracts from large to small, which can effectively guide the heat in the box body 1 to the fan 8 and be discharged from the box body through the fan 8.
