Light chamber hybrid heating and refrigerating constant-temperature system

Abstract

The invention discloses a light chamber hybrid heating and refrigerating constant-temperature system which is arranged beside a combustion chamber and comprises a light chamber, a plurality of heatingcomponents, a temperature sensor and a heat preservation material; the heating components are arranged on the outer side surface of the light chamber, copper pipes are arranged on the heating components, and a heat exchange control module is arranged on one side of each copper pipe. The heating component close to one side of the combustion chamber is a semiconductor chilling plate; a room temperature sensor used for detecting the environment temperature of the outer side of the light chamber is arranged on the outer side of the light chamber, and a connecting position temperature sensor usedfor detecting the temperature of the connecting position is arranged on the connecting position of the light chamber and the combustion chamber. After judging is performed according to signals detected by the temperature sensor, the room temperature sensor and the temperature sensor at the joint, the work of each heating component is independently controlled; semiconductor heating and refrigeration belong to a heat exchange component, so that heat exchange needs to be performed through a copper pipe and water flow in the copper pipes, and a light chamber is uniform and constant-temperature.

Description

technical field [0001] The invention belongs to the field of spectrometers, and relates to a constant temperature system, in particular to a mixed heating and cooling constant temperature system for optical chambers. Background technique [0002] At present, the common method of constant temperature in the greenhouse for spectrometers on the market is to maintain the temperature of the heating element. The optimal constant temperature of the light chamber of the ICP instrument is 28-35°C. , and the temperature stability is not high. After long-term operation of the instrument, it is easy to cause the temperature of the optical chamber near the combustion chamber to rise continuously. The temperature rise is higher than the constant temperature, which makes the constant temperature invalid, which has a great impact on the measurement error of the spectrometer ; In order to further reduce the measurement error and ensure the uniformity of the temperature of the entire optical ...

[0002] At present, the common method of constant temperature in the greenhouse for spectrometers on the market is to maintain the temperature of the heating element. The best constant temperature of the light chamber of the ICP instrument is 28-35°C. , and the temperature stability is not high. After long-term operation of the instrument, it is easy to cause the temperature of the optical chamber near the combustion chamber to rise continuously. The temperature rise is higher than the constant temperature, which makes the constant temperature invalid, which has a great impact on the measurement error of the spectrometer ; In order to further reduce the measurement error and ensure the uniformity of the temperature of the entire optical chamber, a semiconductor optical chamber heating and cooling constant temperature system is specially designed
