Abstract
The utility model relates to an improved heat radiating device of a quick weak light spectrum analysis component in a laser diagnosis instrument, which is composed of a metal outer casing arranged at the periphery of the quick weak light spectrum analysis component, a semiconductor refrigerator and a heat radiator, wherein the refrigeration surface of the semiconductor refrigerator is connected with the metal outer casing, the heat radiating surface of the semiconductor refrigerator is connected with the heat radiator and the outer side of the metal outer casing is coated with a heat preservation layer. A heat radiating fan is arranged in the heat radiator, and an elastic supporting frame is arranged between the heat radiating fan and the heat radiator. When the semiconductor refrigerator is operated, the heat of the quick weak light spectrum analysis component which is absorbed by the refrigeration surface is transferred to the heat radiator and is carried away by airflow generated by the heat radiating fan. The vibrational energy generated by the heat radiating fan is absorbed by the elastic supporting frame when the heat radiating fan is operated, thereby, noise is reduced. The temperature of the metal outer casing is detected by a temperature sensor. When the temperature reaches an upper limit and a lower limit, the semiconductor refrigerator is opened or closed by a temperature controlling circuit board. The utility model can solve the problem of the variation of a spectral curve, which is caused by temperature deviation and prevents diagnosis error from occurring.
