Embodiment
For the problems of the prior art, present solution provides a kind of high temperature aging test box with circulation dehumidification system, by the moisture produced in the constantly removing chamber that circulates, with the object reaching maintenance the temperature inside the box, humidity reaches testing requirements.
A kind of high temperature aging test box 6 with circulating dehumidification device, comprise chamber 6 (high temperature aging test box), described chamber 6 side is passed through and is connected with blast pipe 4, the end face of chamber 6 passes through and is connected with backwind tube 7, blast pipe 4, backwind tube 7 are connected by blower fan 2 in chamber 6 outside, are provided with the drying device for absorbing gas moisture in backwind tube 7 in backwind tube 7.
The thinking of this programme is, chamber 6 is passed through and repeatedly kicks into airduct 4, backwind tube 7, then arranges a blower fan 2, jointly forms the circulation system of closed loop with chamber 6.Because hot-air density is low, be positioned at the top of chamber 6, therefore backwind tube 7 is connected to chamber 6 end face, and the air themperature that blast pipe 4 is carried is slightly lower, and blast pipe 4 is connected to bottom surface, casing side.Blower fan 2 is as a part for the circulation system, and it is directly serially connected on pipeline, and the air inlet of blower fan 2 is connected with backwind tube 7, and air outlet is connected with blast pipe 4, and when namely blower fan 2 operates, what agitate is air in the whole circulation system.The blower fan 2 of such setting, the air in environment is not blown in chamber 6 by it, is conducive to keeping the temperature in chamber 6.Namely blower fan 2 only plays and to make in chamber 6 air along the object of tube runs.Air in chamber 6 is when backwind tube 7 flows, and through drying device, the dried device of the moisture in air absorbs, by continuous cyclic process, effectively can remove the moisture in chamber 6, make to maintain the lower level of humidity in chamber 6 all the time, to meet testing requirements.
As shown in Figure 1, in this programme, drying device comprises drying 8, and drying 8 is arranged in series on backwind tube 7, is provided with drying agent in drying 8.By arranging drying 8, when the air in chamber 6 is through drying 8, the absorption of dried dose of the moisture in air, effectively can absorb moisture.The method is simple to operate, flexible and efficient, and use cost is extremely low, and the humidity retention time is long.
More specifically, be provided with the dividing plate with through hole in drying 8, described drying agent is arranged on dividing plate.Due to the direction that air flowing wind direction is from backwind tube 7 to blast pipe 4, and when drying 8 is vertically arranged, the position of drying agent can not be subject to the impact of wind-force flowing.Drying 8 sidewall passes through the charge door 9 be connected with lid, drying agent is added by charge door 9; When needing to add drying agent, open the lid of charge door 9, close again after interpolation.
The output power of blower fan 2 determines speed air flow, with the humidity level in case, under the driving of blower fan 2, in chamber 6, air flows through drying 8 and finally returns chamber 6 realization dehumidifying, so, dehumidification operation essence is exactly solve " when blower fan 2 starts, and running how long, how long starts once " problem.Affect by factors such as system sealing level, ambient humidity, subjects volume, subjects water cut, chamber 6 humidity Changing Pattern is widely different, therefore, wanting warranty test case 6 humidity remains in claimed range, need first adopt artificial dehumidifying, sum up humidity Changing Pattern, then adopt self-timing to dehumidify, the change along with humidity Changing Pattern needs real time modifying self-timing length.
In order to have to regulate and control more accurately to case humidity, blower fan 2 is provided with frequency converter 1; Be provided with Temperature Humidity Sensor 5 in chamber 6, Temperature Humidity Sensor 5 is connected with the display 10 with processor being arranged on chamber 6 outside, and described blower fan 2 is connected with processor.
By placement processor and sensor, define a kind of automatic regulating system.When Temperature Humidity Sensor 5 detects that case humidity exceedes setting threshold value, by information feed back to processor, processor regulates and controls blower fan 2, to accelerate/to slow down speed air flow; Humiture simultaneously in case also can show on display 10 in real time, observes regulation and control at any time for operating personnel.
In pipeline connection procedure, there is higher requirement to leakproofness.In this programme, blast pipe 4, backwind tube 7 are connected by pipe clamp 3 with between casing, between drying 8 with backwind tube 7.Pipe clamp 3 comprises an endless tube 301, and the two ends of endless tube 301 are serially connected with the first connecting pipe 303 and the second connecting pipe 305 respectively, and the circumference along endless tube 301 outside is surrounded with endless belt 302, and two ends of endless belt 302 are provided with the fixing card 304 cooperatively interacted.
When needing connection two pipelines, two pipelines are extend in endless tube 301 respectively from the first connecting pipe 303, second connecting pipe 305, is temporarily fixed, but the fixing card 304 at endless belt 302 two ends is fixed.Endless tube 301 can be out of shape to a certain extent, by the locking of endless belt 302, endless tube 301 is out of shape, extrudes the mouth of pipe of two pipelines, the end of pipeline is fastened in endless tube 301.This structure also can keep the leakproofness connected effectively.
The step utilizing this device to carry out testing is with reference to as follows:
1. experimental subjects is put on chamber 6 built-in article rack, set temperature, start heating;
2. dry bucket inserted by drying agent;
3. the temperature gathered by Temperature Humidity Sensor 5 show on display 10 stable after, manual shift chamber 6 desired temperature, makes the magnitude value that Temperature Humidity Sensor 5 Temperature displaying value stabilization is requiring;
4. temperature stabilization and after meeting the demands, starts blower fan 2, experimental box humidity is reduced to requirement of experiment level;
5. when temperature, humidity meet experiment condition simultaneously and keep more than 10 minutes time, start to test timing;
6. regularly start circulating fan 2 as required, add qualified drying agent as required, keep chamber 6 humidity temperature to maintain within the scope of requirement of experiment;
7. repeat the 6th step, until off-test.
The drying agent used in this programme, can regenerate through heating process, and can be cycled to repeat utilization, therefore use cost is extremely low.
