Technical field
The present invention relates to technical field of optical instrument more particularly to optical instrument low temperature environment test boxs.
Background technique
Low temperature detection is a basic test project of instrument.The biggish optical instrument in space is measured for part, if
Simulated environment is detected using low temperature, traditionally greenhouse is limited the requirement for being often unable to satisfy test, such as long distance laser by place
Positioning or distance-measuring equipment etc., and large-scale low temperature test room is built and its operates in economic indicator often without feasible
Property.Therefore, it needs a kind of to put into small and the equipment of low-temperature test environment can be provided for optical instrument.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of optical instrument low temperature environment surveys at low cost, easy to operate
Try case.
To solve the above problems, optical instrument low temperature environment test box of the present invention, it is characterised in that: the test box
Be made including vacuum double-layer glass and it is interior set upper layer cavity, middle layer cavity, lower layer's cavity cabinet and be located at the top of the box
The single-chip microcontroller being connected with power supply；Between the upper layer cavity and the middle layer cavity, the middle layer cavity and lower layer's cavity
Between be equipped with partition, the partition be equipped with symmetrical venthole；The upper layer cavity by air circulating umbilical directly with
Lower layer's cavity is connected；The side of the upper layer cavity is equipped with the fan of translator；The upper layer cavity and the middle layer chamber
The partition of body joint is equipped with refrigerating fluid circulation pipe, the external refrigeration machine of refrigerating fluid circulation pipe；The side of lower layer's cavity
Equipped with temperature sensor；The single-chip microcontroller is connected with the fan, the temperature sensor respectively, and external connection keyboard and liquid crystal
Display screen.
Compared with the prior art, the present invention has the following advantages:
1, since the cabinet in the present invention is that vacuum double-layer glass is made and interior sets upper layer cavity, middle layer cavity, lower layer's chamber
Therefore body solves the problems, such as that optical instrument carries out big-bang testing, while dual-layer vacuum glass in small range low temperature environment
With thermal insulation benefits, the intensity of heat exchange inside and outside cabinet is greatly lowered, additionally it is possible to frosting inside and outside glass be avoided to make pairwise testing
The influence of optical path.
2, the side of cavity at the middle and upper levels of the invention is equipped with the fan of translator, and upper layer cavity and middle layer cavity joint
Partition is equipped with refrigerating fluid circulation pipe, therefore, is reached by fan air-supply and air and refrigerating fluid circulation pipe in cabinet is allowed to carry out heat
The purpose of air circulation between exchange and three layers.
3, in the present invention therefore the side of lower layer's cavity can be used for the measurement of the temperature inside the box equipped with temperature sensor.
4, the present invention is equipped with partition between cavity and middle layer cavity, between middle layer cavity and lower layer's cavity at the middle and upper levels, should
Partition is equipped with symmetrical venthole, and therefore, the steady air current of middle layer air circulation is symmetrical, can effectively reduce because of air stream
Dynamic asymmetric and caused to optical instrument measurement influence.
5, the present invention use single-chip microcontroller control fan work to adjust heat exchange to reach temperature controlled effect, warm in real time
Degree, setting temperature and control range are shown by LCD.Compared with the test space of Conventional cryogenic room, the present invention can be to be measured
Optical instrument provides the low-temperature test environment not limited by spatial dimension.
6, the present invention is at low cost, easy to operate.
Detailed description of the invention
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural diagram of the present invention.
In figure: 1-upper layer 2-middle layer of cavity 3-lower layer of cavity cavity 4-cabinet, 5-refrigeration machine, 6-refrigerating fluid
Circulation pipe 7-fan, 8-air circulating umbilical, 9-temperature sensor, 10-venthole.
Specific embodiment

It is equipped with partition between upper layer cavity 1 and middle layer cavity 2, between middle layer cavity 2 and lower layer's cavity 3, on the partition
Equipped with symmetrical venthole 10；Upper layer cavity 1 is directly connected with lower layer cavity 3 by air circulating umbilical 8；Upper layer cavity 1
Side be equipped with translator fan 7；Upper layer cavity 1 and the partition of 2 joint of middle layer cavity are equipped with refrigerating fluid circulation pipe 6,
The external refrigeration machine 5 of refrigerating fluid circulation pipe 6；The side of lower layer's cavity 3 is equipped with temperature sensor 9；Single-chip microcontroller respectively with fan 7,
Temperature sensor 9 is connected, and external connection keyboard and liquid crystal display.
In use, being passed through power supply, the present invention enters operating status.Setting control temperature and control model are inputted by keyboard
It encloses, temperature is setting control temperature, and range is setting control allowed band, for example sets control -25.5 DEG C of ranges of temperature as 0.5
DEG C, control the temperature inside the box is sought between -26 DEG C to -25 DEG C.The temperature inside the box and setting temperature measured by temperature sensor 9
Degree and range are compared, and test temperature just stops motor operating lower than -26 DEG C and stops refrigeration, and test temperature is higher than -25 DEG C
Just control motor again operation start freeze, just by temperature control between -25 DEG C to -26 DEG C, when do not change control temperature and
Range and stop refrigeration when can by keyboard motor control switch close motor complete.Liquid crystal display include Current Temperatures,
Current control temperature, range and motor switch state.
