Description
Technical field
The present invention relates to thermal insulation case, the thermal insulation case using under especially a kind of high and low temperature environment.
Background technology
As adopted testing arrangement to carry out exercise performance testing experiment to mechanism to be measured at high and low temperature environment, cold overheated because of the mistake of environment, great majority test cannot normally be used with precision instrument or equipment, affect the carrying out of test job.Because the high and low temperature environment sealing requirements of simulation is very high, so testing arrangement can not be placed in extraneous normal temperature environment again.
For tester under high and low temperature environment can normally be worked, in high and low temperature environment, designing a thermal insulation case is a kind of feasible method.The incubator of conventional sealing, long-time use can make inner approaching with external temperature; In addition can be by the incubator that heat inside or refrigeration part holding temperature is constant, as be similar to the device etc. of refrigerator, but incubator seals, in case instrument can not with mechanism connection to be measured, the outer parameters of incubator cannot be detected, and the extraneous temperature difference that can adapt to is little.Number of patent application is that 200810220356.0 " incubator " proposed a kind of incomplete sealing, can improve by inner heating member the device of temperature, but this incubator can only be applicable to low temperature environment.Thereby in the high and low temperature environment of the irregular variation of temperature, also there is no at present similar, well behaved incubator design.
Summary of the invention
In order to overcome the poor-performing of existing thermal insulation case, the deficiency that can not be applicable to use under high and low temperature environment, the invention provides a kind of functional, be effectively applicable to the thermal insulation case that uses under high and low temperature environment.
The technical solution adopted for the present invention to solve the technical problems is:
A thermal insulation case under high and low temperature environment, described thermal insulation case comprises casing and bottom, described casing tips upside down on bottom; Described casing comprises box frame, described box frame internal layer covers the upper heat-conducting plate that can lead to refrigeration or heat upper circulation water coil pipe, upper thermal insulation layer is filled in described box frame outside, and described casing top has upper hot and cold water to import and export, and described upper hot and cold water is imported and exported and is communicated with described upper circulation water coil pipe;
Described bottom upper surface is for leading to the lower heat-conducting plate that freezes or heat lower recirculated water coil pipe, described lower heat-conducting plate below is fixed with case back welding frame, described bottom intermediate layer is lower thermal insulation layer, described bottom half has lower hot and cold water to import and export, and described lower hot and cold water is imported and exported and is communicated with described lower recirculated water coil pipe.
Further, the Si Ge angle, top of described box frame is fixed by thermal insulation feet and case overhead welding frame, there is sealed groove described bottom upper surface outer ring, in described sealed groove, fill sealing strip, the bottom of described incubator has strip through-hole opening, described strip gab nexine and outer opening part all adopt flexible sealing strip sealing, described strip through-hole opening also can be split into other shapes according to the motion morphology of testing arrangement and connected mode, the uniform thermal insulation guide pin bushing of bottom of described incubator, the thermal insulation cushion block on described thermal insulation guide pin bushing and installation frame is installed location.
In described incubator, be furnished with temperature sense assembly, described a set of water chiller/heater is imported and exported with described upper hot and cold water, lower hot and cold water is imported and exported and is communicated with, and described water chiller/heater comprises for freezing or heat the temperature control module of controlling the temperature that enters the water in upper circulation water coil pipe and lower recirculated water coil pipe according to the variation of insulation the temperature inside the box.
Described thermal insulation guide pin bushing, thermal insulation feet etc. can adopt polytetrafluoroethylene (PTFE), the temperature-resistant materials such as the flexible heat-insulating cloth of described flexible sealing strip adoption or silica gel sealing bar.
On casing bottom, have air inlet, described air inlet is in communication with the outside by pipeline, and nitrogen is linked in incubator by pipeline, and described pipeline outer-layer has insulation material, and the cable of testing arrangement etc. is also connected with the external world in nitrogen pipeline.
Described box outer surface covers package board on one deck, and described case back welding frame covers package board under one deck outward.
Technical conceive of the present invention is: the outer field package board of casing can reflecting part heat radiation and kept the profile of casing; The hard foam in intermediate layer, can intercept most heat transmission; Internal layer adopts band can lead to refrigeration or heats the high copper coin of heat transfer efficiency of recirculated water coil pipe, and heat or the cold air that the external world can be imported into are taken incubator out of.A set of hot and cold water unit is installed in external environment condition, and described water chiller/heater can heat also and can freeze, and according to the variations in temperature of incubator, provides circulating water or hot water.
For convenient debugging with install, we become the casing of a back-off and the lower bottom cover of plane by INSULATION DESIGN, and between interconnective casing and bottom, we have designed sealed groove, and filling flexible heatproof foam seal bar therebetween increases the sealing of incubator.Facilitate the installation of testing arrangement, under normal temperature environment, mechanism to be measured is carried out to exercise performance test and also casing can be taken away.Between incubator and installation frame, without with screw fastening, by its gravity and positioned internal piece, naturally locate; Locating piece is thermal insulation material, has avoided the heat exchange between material.
For with high and low temperature environment under moving link to be measured be communicated with, on the bottom of incubator, output strip gab, at strip gab upper and lower surface place, adopt flexible heat-insulating cloth sealing, make heat exchange herein reach minimum.When if the tester in case is connected by suspension strop with mechanism to be measured, the flexible heat-insulating cloth sealing that guarantees opening part does not exert an influence to the motion of suspension strop, at suspension strop, put the device of a rhumbatron or other types outward, initiatively follow the motion of suspension strop, make sealing at needs place automatic open-close, both guaranteed and extraneous being communicated with, again the temperature in casing had been produced to minimum impact.
Because air contains steam, meeting glaciation under utmost point cold environment, if incubator internal memory has air, can have impact to bottom end opening place so, due to nitrogen environmental protection, density is large, can reduce the thermal shock at place, gap, therefore at whole incubator, blow normal temperature nitrogen, discharge air in case, to keep pressure-fired in incubator.Nitrogen is linked in incubator by pipeline, and pipeline outer-layer has insulation material, simultaneously, the cable of testing arrangement etc. is also introduced in nitrogen pipeline, because pipeline has insulation material outward, the temperature remains within the normal range for the nitrogen in pipeline, can prevent that the high and utmost point low temperature from impacting cable.
Beneficial effect of the present invention is mainly manifested in: functional, to facilitate testing arrangement installation, be effectively applicable to use under high and low temperature environment.
