Technical field
The utility model relates to attemperating unit, and especially a kind of semiconductor pump gushes the laser attemperating unit.
Background technology
Semiconductor chilling plate is the temperature control element of present main flow, has the heating of can freezing, structure of whole solid state, advantage such as reliability is high, the life-span is long, use widely military, medical, scientific research, civilian or the like aspect.The temperature difference at its refrigerating capacity and self material behavior, the voltage that applies, two ends etc. is relevant.
One end in contact of traditional semiconductor chilling plate is treated the temperature control device, other end contact radiator.The temperature of temperature control device is treated in temp probe monitoring in real time; And feed back to cooling piece electricity and drive, temperature through the temp probe monitoring and design temperature poor calculates the electric energy that need provide for cooling piece; Heat is transferred to the other end from an end of cooling piece, thereby realize temperature control.
But because the temperature difference at the operating efficiency of cooling piece and two ends is closely related, so semiconductor temperature-control device of the prior art, the efficient of cooling piece receives the radiating effect restriction of radiator.After the semiconductor temperature-control device starts; Cooling piece heat under the cooling piece electricity drives can flow into the other end from an end of cooling piece; Cooling piece l with treat that an end temperature of temperature control device contacts gradually changes to design temperature, opposite variation also can take place in radiator temperature.Because the thermal capacitance of radiator is limited; It is very fast to make radiator temperature change; Cause cooling piece to treat that the contacted end of temperature control device and the other end temperature difference increase rapidly, thereby cause the operating efficiency of cooling piece to reduce rapidly thereupon, then can make and treat that the temperature control device reaches design temperature time principal.Be that the cooling piece efficient in the semiconductor temperature-control device constantly descends with the increase of the cooling piece two ends temperature difference in the prior art, thereby be affected the start-up time that causes treating the temperature control device.

Embodiment
Combine accompanying drawing and preferred embodiment that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of semiconductor pump as shown in Figure 1 gushes the laser attemperating unit; Comprise semiconductor chilling plate, temperature sensor and temperature-control circuit; The output of described temperature sensor connects the input of temperature-control circuit, and the output of described temperature-control circuit connects the input of semiconductor chilling plate.
The noise spectra of semiconductor lasers that is mainly used in semiconductor chilling plate heats and freezes; Temperature sensor is mainly used in and obtains laser temperature.Temperature-control circuit is mainly used in the reading temperature sensor temperature, and according to laser temperature adjustment in real time to the control mode of semiconductor chilling plate, with temperature stabilization in control range.
After semiconductor pump laser is started working, send this temperature to temperature-control circuit after the working temperature of temperature sensor read semiconductor laser, temperature-control circuit is controlled the TE semiconductor chilling plate according to the current lasers temperature; When temperature was higher than T4, the control semiconductor chilling plate freezed, and every separated set time (like 500ms) samples to temperature; When temperature is lower than T2; The control semiconductor chilling plate quits work, because there are temperature gradient in sample temperature and practical semiconductor temperature, the temperature that therefore reads can continue to reduce; If temperature is reduced to T1 when following; Temperature control circuit is started working, and the control semiconductor chilling plate heats work, and the control cooling piece quits work when temperature is higher than T3.This mode can effectively be controlled conductor temperature, with temperature stabilization in certain operation interval.And can significantly reduce the power consumption of TE refrigerator.
