Description
Technical Field
[0001] The utility model relates to the technical field of liquid chromatographs, in particular to a liquid chromatograph with a heat dissipation structure. Background Art
[0002] Liquid chromatograph is a commonly used analytical instrument, widely used in chemistry, biology, environment and other fields. Its principle is based on the difference in the distribution ratio of the mixture between liquid-solid or two immiscible liquids. It is an instrument that first separates the mixture and then analyzes and identifies it. The application range of liquid chromatograph is very wide, and it can be used in various fields such as biochemistry, food analysis, pharmaceutical research, environmental analysis, inorganic analysis, etc.
[0003] At present, the internal components of the existing liquid chromatographs will generate a lot of heat during use. Most chromatographs only dissipate heat by opening heat dissipation holes. However, the chromatograph will generate a lot of heat after working for a long time. Discharging heat only through the heat dissipation holes may make it difficult to discharge the heat inside the chromatograph and cause it to accumulate, which may cause damage to the internal electrical components of the chromatograph. At the same time, the heat dissipation holes will accumulate some dust and impurities for a long time and enter the chromatograph, thereby reducing the service life of the chromatograph and causing the practicability of the chromatograph to decrease. Therefore, we propose a liquid chromatograph with a heat dissipation structure to solve the above problems. Utility Model Content
