The dew point detecting device with high heat dissipation may be classified into various types according to the cooling method and the detection control method used. The dew point detection device with high heat dissipation can utilize a thermoelectric refrigerator (Peltier element) to cool the dew-layer sensor, so that water vapor in gas is condensed on the dew-layer sensor to generate dew or frost, meanwhile, signals collected by the receiver enable the dew or frost on the dew-layer sensor and the water vapor in the gas to be in a balanced state through an automatic control circuit, and then a thermometer is used for accurately measuring the temperature of the dew-layer sensor, namely the temperature of a dew or frost layer, so that the dew point temperature of the gas is obtained, and the humidity in the gas is also indirectly measured. The dew layer sensor comprises a mirror surface, a luminous tube, a receiving tube or a surface acoustic wave device and other components.

The dew point temperature of the gas is that the water vapor in the gas is cooled to condensed phase under the condition of isobaric pressure, and then the temperature of the dew layer sensor is controlled to enable the water vapor in the gas and the flat surface of water or ice to be in a thermodynamic phase equilibrium state, wherein the temperature of the dew layer is the dew point temperature of the gas.

The receiving cavity 1024 is substantially cylindrical and has a cross-sectional area greater than that of the limiting cavity. When the lower end of the heat conducting structure 105 is clamped at the lower end of the protrusion 1023, the lower end of the heat conducting structure 105 is located in the accommodating cavity 1024. The accommodating cavity 1024 has a certain height, and the lower end of the sidewall thereof is clamped in the clamping groove 1094, so as to realize the matching installation of the detection cover 102 and the connecting portion 1092.

The specific working process of the dew point detection device is as follows: water vapor in the operating environment sweeps over the upper surface of the mirror 103 as it passes through the detection chamber. When the temperature of the upper surface of the mirror surface 103 is higher than the dew point temperature of the gas, the upper surface of the mirror surface 103 is in a dry state. At this time, under the control of the control system, the photoelectric detection device 101 transmits a signal to the remote control host through the transfer control board 110 and the aviation connector 111, and receives a feedback signal from the remote control host, and the feedback signal is compared and amplified by the control loop to drive the refrigeration sheet 107 to refrigerate. When the temperature of the upper surface of the mirror surface 103 is reduced to be lower than the dew point temperature of the gas, the upper surface of the mirror surface 103 begins to dewfall to form condensate, at this time, the photoelectric detection device 101 continuously transmits a signal to the remote control host through the transfer control board 110 and the aviation connector 111, receives a feedback signal from the remote control host, compares and amplifies the feedback signal through the control loop according to the change of the feedback signal, adjusts the excitation current of the refrigerating sheet 107, changes the refrigerating power of the refrigerating sheet 107, and enables the temperature of the upper surface of the mirror surface 103 to be consistent with the dew point temperature of the gas. At this time, the temperature of the mirror surface 103 is detected by the thermometer 106, and the dew point or frost point in the gas can be obtained.
