Description
Technical field
The present invention relates to technical field of optical instrument, particularly relate to optical instrument low temperature environment test box.
Background technology
Low temperature detection is a basic test project of instrument.For the optical instrument that part measurement space is bigger, if using low temperature detection simulated environment, greenhouse is limited the requirement that often cannot meet test by place traditionally, such as long distance laser location or distance-measuring equipment etc., and large-scale low temperature test room construction and operate in the most not there is in economic indicator feasibility.Therefore, need badly a kind of put into little and can for optical instrument provide low-temperature test environment equipment.
Summary of the invention
The technical problem to be solved is to provide a kind of low cost, optical instrument low temperature environment test box simple to operate.
For solving the problems referred to above, optical instrument low temperature environment test box of the present invention, it is characterised in that: this test box include vacuum double-layer glass make and in set upper strata cavity, middle level cavity, lower floor's cavity casing be located at the single-chip microcomputer that described casing top is connected with power supply；Between described upper strata cavity and described middle level cavity, being equipped with dividing plate between described middle level cavity and described lower floor cavity, this dividing plate is provided with symmetrical passage；Described upper strata cavity is directly connected with described lower floor cavity by air circulating umbilical；The side of described upper strata cavity is provided with the fan of translator；Described upper strata cavity is provided with refrigerating fluid circulation pipe with the dividing plate of cavity joint, described middle level, this external refrigeration machine of refrigerating fluid circulation pipe；The side of described lower floor cavity is provided with temperature sensor；Described single-chip microcomputer is connected with described fan, described temperature sensor respectively, and external connection keyboard and LCDs.
The present invention compared with prior art has the advantage that
1, due to the casing in the present invention be vacuum double-layer glass make and in set upper strata cavity, middle level cavity, lower floor's cavity, therefore, solve the problem that optical instrument carries out big-bang testing in little scope low temperature environment, dual-layer vacuum glass has thermal insulation benefits simultaneously, intensity of heat exchange casing inside and outside is greatly lowered, additionally it is possible to avoid frosting inside and outside glass to cause the impact on optical system for testing.
2, the side of present invention cavity at the middle and upper levels is provided with the fan of translator, and the dividing plate of upper strata cavity and cavity joint, middle level is provided with refrigerating fluid circulation pipe, therefore, reach to allow the purpose of the air circulation that air and refrigerating fluid circulation pipe carry out between heat exchange and three layers in casing by fan air-supply.
3, in the present invention, the side of lower floor's cavity is provided with temperature sensor, therefore, can be used for the measurement of the temperature inside the box.
4, between present invention cavity at the middle and upper levels and middle level cavity, between middle level cavity and lower floor's cavity, it is equipped with dividing plate, this dividing plate is provided with symmetrical passage, therefore, the steady air current of middle layer of air circulation is symmetrical, can effectively reduce, because air flowing is asymmetric, optical instrument be measured the impact caused.
5, the present invention uses Single-chip Controlling fan work to regulate heat exchange to reach temperature controlled effect, real time temperature, arranges temperature and span of control is shown by LCD.Compared with the test space of Conventional cryogenic room, the present invention can be that optical instrument to be measured provides the low-temperature test environment not limited by spatial dimension.
6, low cost of the present invention, simple to operate.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail.
Fig. 1 is the structural representation of the present invention.
In figure: 1 upper strata cavity 2 middle level cavity 3 lower floor cavity 4 casing 5 refrigeration machine 6 refrigerating fluid circulation pipe 7 fan 8 air circulating umbilical 9 temperature sensor 10 passage.
Detailed description of the invention
As it is shown in figure 1, optical instrument low temperature environment test box, this test box include vacuum double-layer glass make and in set upper strata cavity 1, middle level cavity 2, lower floor's cavity 3 casing 4 be located at the single-chip microcomputer that casing 4 top is connected with power supply.
Between upper strata cavity 1 and middle level cavity 2, being equipped with dividing plate between middle level cavity 2 and lower floor's cavity 3, this dividing plate is provided with symmetrical passage 10；Upper strata cavity 1 is directly connected with lower floor cavity 3 by air circulating umbilical 8；The side of upper strata cavity 1 is provided with the fan 7 of translator；Upper strata cavity 1 is provided with refrigerating fluid circulation pipe 6 with the dividing plate of middle level cavity 2 joint, this external refrigeration machine of refrigerating fluid circulation pipe 65；The side of lower floor's cavity 3 is provided with temperature sensor 9；Single-chip microcomputer is connected with fan 7, temperature sensor 9 respectively, and external connection keyboard and LCDs.
During use, being passed through power supply, the present invention enters running status.By input through keyboard setup control temperature and span of control, temperature is setup control temperature, and scope is setup control allowed band, and such as-25.5 DEG C of scopes of setup control temperature are 0.5 DEG C, it is simply that the temperature inside the box to be controlled is between-26 DEG C to-25 DEG C.The temperature inside the box measured by temperature sensor 9 and design temperature and scope are compared, test temperature just stops motor rotation less than-26 DEG C and stops refrigeration, test temperature just controls motor operation start again refrigeration higher than-25 DEG C, just temperature is controlled between-25 DEG C to-26 DEG C, motor can be closed by motor control switch on keyboard when not changing control temperature and scope and stop refrigeration and complete.Liquid crystal display includes Current Temperatures, currently controls temperature, scope and motor switch state.
