The radiator is equipped with the semiconductor refrigeration sheet, one surface of the semiconductor refrigeration sheet is fixedly connected with the radiator, and the other surface is equipped with the refrigeration element on which the temperature sensor is arranged. The utility model provides the refrigeration device of the CCD detector which is simple in structure and is simple and effective.
Description
Technical field
The utility model relates to a kind of refrigerating plant, is specifically related to a kind of refrigerating plant of ccd detector.
Background technology
In ccd detector, because the technical characterstic of CCD chip itself, determined its dark current noise and to read noise all very big under the normal temperature working condition, influence its final image imaging results.Especially under the X ray environment, illumination own is very low, thus The noise to compare the visible light environment for signal noise ratio (snr) of image more abominable.
The utility model content
The technical problem that the utility model will solve is the defective that overcomes prior art, provides a kind of simple in structure, simple effectively refrigerating plant.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of refrigerating plant of ccd detector; Comprise radiator, semiconductor chilling plate, hail, temperature sensor, said radiator is provided with semiconductor chilling plate, and said semiconductor chilling plate one side is affixed with radiator; Another side is provided with hail, and said hail is provided with temperature sensor.
Further; Said radiator is by " returning " font cylinder that cavity is arranged in, a rectangular slab with perpendicular to the affixed successively formation of the fin of rectangular slab; Said " returning " font cylinder and fin are arranged at said rectangular slab both sides respectively, and said " returning " font cylinder is positioned at the centre position of said rectangular slab; Said semiconductor chilling plate is positioned at the cavity of said " returning " font cylinder, and said semiconductor chilling plate one side is connected with the radiator rectangular slab, and another side is connected with hail.
Further, said temperature sensor is positioned at said hail side.
Further, the fin of said radiator is at least a slice, evenly configuration.
Further, also be provided with fan on the said radiator, said fan is positioned at fin one side.
Further, said fan thickness is consistent with the fin height.
The beneficial effect of the utility model is: according to the characteristics of CCD chip itself, 7 degrees centigrade of every reductions, its dark current noise with read noise and all reduce one times, so this device can be reduced to 1/32 of room noise with noise at most.The utility model can remain on the working temperature of CCD chip room temperature to the arbitrary temp scope that is lower than 40 degrees centigrade of room temperatures, and error is no more than 0.5 degree centigrade.Thereby the raising signal noise ratio (snr) of image obtains the better pictures quality.

Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
Like Fig. 1,2, shown in 3; Radiator 1 is by " returning " font cylinder that cavity is arranged in, a rectangular slab with perpendicular to the affixed successively formation of the fin of rectangular slab; " return " font cylinder and fin and be arranged at said rectangular slab both sides respectively, " returning " font cylinder is positioned at the centre position of rectangular slab.
As shown in Figure 5; A kind of refrigerating plant of ccd detector; Comprise radiator 1, semiconductor chilling plate 2, hail 4 and temperature sensor 3, radiator 1 is provided with semiconductor chilling plate 2, and semiconductor chilling plate 2 one sides are affixed with radiator 1; Another side is provided with hail 4, and hail 4 is provided with temperature sensor 3.
Like Fig. 3,5 said, semiconductor chilling plate 2 is positioned at " returning " font cylinder cavity of radiator 1, and semiconductor chilling plate 2 one sides are connected with radiator rectangular slab upper surface, and this face is a hot side; Another side is connected with hail 4, and this face is a huyashi-chuuka (cold chinese-style noodles).
Like Fig. 5, shown in 6, temperature sensor 3 is positioned at the side of hail 4.
Partial enlarged drawing as shown in Figure 4, the fin of radiator 1 evenly disposes.Fin one side at radiator 1 also is provided with fan 5.
The thickness of fan 5 as shown in Figure 5 is consistent with the fin height, convenient the placement.
Operation principle: because the decision of the characteristics of semiconductor chilling plate 2; Its cold and hot surface maximum temperature difference is about 40 degrees centigrade, therefore connects hail 4 with huyashi-chuuka (cold chinese-style noodles) and directly contacts the CCD chip back afterwards, and hot side is connected to radiator 1 and fan 5; Temperature sensor 3 places in the middle of the hail 4; Under normal heat radiation situation, the hot side of semiconductor chilling plate is kept near ambient temperature, so huyashi-chuuka (cold chinese-style noodles) can guarantee that temperature is lower than 40 degrees centigrade of room temperatures at most.
After temperature sensor 3 placed hail 4; The huyashi-chuuka (cold chinese-style noodles) that hail 4 is connected CCD chip lower surface and semiconductor chilling plate 2; Hot side with semiconductor chilling plate 2 is connected to radiator 1 then, and the signal of temperature sensor 3 is connected to the peripheral temperature control circuit, gives semiconductor chilling plate 2 power supplies with the power supply of 12V5A; Through temperature control system control is the working temperature of may command CCD chip, and control range is room temperature-be lower than 40 degrees centigrade of room temperatures
.
What should explain at last is: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
