Technical field
The present invention relates to a kind of test performing device for deep low-temperature substance, the solar battery array that is used for space craft is simulated the device that launches test.
Background technology
Along with developing rapidly of space technology, bearing the vital task that the energy is provided for aircraft as the chief component-solar battery array of aerospace craft, aircraft is in the vacuum environment orbital motion of exoatmosphere, will replace repeatedly through the high-temperature region of sunlight direct projection and the low-temperature space of shade, therefore the solar battery array real work is in the environment of a high and low temperature alternative circulation, for it is launched in orbit smoothly, for aircraft provides the energy, it is the reliable guarantee that guarantees its operate as normal in space that imitation high and low temperature environment condition makes a service test on the ground, past, this class test conventional method was to carry out in large-scale thermal vacuum jar, test period is very long and expense is expensive, can't carry out the high low temperature extensibility of large-area solar cell battle array and can test because of being subjected to thermal vacuum tank volume influence again." high and low temperature simulation method and object developing test device " patent of invention of the applicant's application in 2004 has solved above-mentioned technical problem.
But high speed development along with Space Science and Technology, fly to remote celestial body and carry out scientific exploration in order to satisfy aerospace craft, this area has proposed the solar battery array cryogenic property need be under-185 ℃～-195 ℃ profound hypothermia environmental conditions, and the requirement that can launch smoothly behind the constant temperature through 24 hours, and " high and low temperature simulation method and object developing test device " minimum permissible temperature is-110 ℃, can't satisfy * *-1 solar battery array profound hypothermia expansion experimental condition.
Summary of the invention
The present invention solves above-mentioned existing in prior technology technical problem, and a kind of test performing device for deep low-temperature substance is provided
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of test performing device for deep low-temperature substance, comprise the A main box of a closed and at least one auxiliary box body that links to each other, a side is provided with the profound hypothermia ice chest in the described A main box, the profound hypothermia ice chest is provided with sealed door towards A main box place, the cold screen of casing is set on the profound hypothermia ice chest inwall, and the sealed door inboard is provided with Men Lengping; Solar battery array is installed in the profound hypothermia ice chest by a unwheeling with the simulation wall with the gathering form, solar battery array is suspended on two long tracks, two long tracks hang on the suspension at A main box top, one end of two long tracks is installed on the inside of profound hypothermia ice chest, and the other end is hung in the A main box.
As preferably, it is pitch-dark that the medial surface of cold screen of described casing and Men Lengping is coated with low temperature resistant F-26, has the specific radiation function.
As preferably, be connected with B, C, three auxiliary box bodies of D on the described A main box, between A main box and three auxiliary box bodies electronic isolating door is set respectively.
It is-90 ℃～-100 ℃ that the present invention brings up A main box environment temperature, has satisfied the XX-1 solar battery array and has launched the instantaneous temperature requirement and launch the space, has dwindled the profound hypothermia ice chest-185 ℃～-195 ℃ and the external environment temperature difference, and has dwindled the volume of profound hypothermia ice chest.The present invention is refrigerant with the liquid nitrogen, liquid nitrogen from cryogenic liquid tank enters respectively in cold screen of casing and the Men Lengping by a plurality of low temperature control valves, two-phase flow liquid nitrogen behind the transmission cold enters the A main box and gasification sprays the main box in A, makes the cooling low-temperature receiver of A main box.Profound hypothermia is launched the test space different parts and is provided with 13 temperature-sensing elements, can regulate corresponding low temperature control valve opening automatically according to each temperature spot image data and guarantee the temperature field uniformity.
Because the present invention is arranged on the profound hypothermia ice chest in-90 ℃～-100 ℃ the A main box, dwindled and the external environment temperature difference, adopted again in the cold screen of casing and Men Lengping of heat sink formula, effect is obvious, do not adopt local liquid nitrogen spraying to regulate the temperature field uniformity and do not adopting the liquid helium spray to replenish under the operating mode of refrigeration, it is 3.1 ℃/min that the test space minimum temperature reaches-196 ℃ of average temperature drop rates, the temperature field uniformity is ± 4.5 ℃ during the constant temperature, adopt local a small amount of hydrojet can be adjusted to ± 3 ℃.Test shows that effect of the present invention is obvious, can omit liquid helium in the test and replenish the refrigeration operation, and 200,000 yuan of liquid helium expenses are saved in each test (in insulation 24h), and save test period, and economic results in society are remarkable.
