Device 8；Wherein quenching medium is liquid nitrogen, and high power heater is Infrared High-Power heating unit.Normal temperature air is by room temperature sky
Gas input unit 8 inputs the preceding deaerating plant 9 that passes through in chamber ontology and carries out deoxygenation to normal temperature air.In chamber ontology also
It is provided with temperature sensor 5.Humidity sensor is additionally provided in chamber ontology.Power control device is additionally provided with, passes through work(
Rate control device controls the heating power of Infrared High-Power heating unit.Chamber ontology is also associated with vacuum pump 10.Chilling fills
It puts and Test section is connected to by a flow valve 2.It is additionally provided with warning device 3.Warning device 3 is LED light.It is additionally provided with manipulation
Device 4, control device include control device, control device and temperature sensor, humidity sensor, flow valve 2, warning device 3
And air delivery arrangement is connect with vacuum pump.
Description of the drawings
The high/low-temperature impact that Fig. 1 is the application tries case general structure schematic diagram.
Specific embodiment
Refer to the attached drawing, the low temperature impact test box of the application include chamber ontology 6, and chamber ontology 6, which is connected with, to be filled
Expire the quenching apparatus 1 of quenching medium, be additionally provided with high power heater 7 in chamber ontology 6, chamber ontology is connected with often
Warm air input unit 8；Wherein quenching medium is liquid nitrogen, and high power heater is Infrared High-Power heating unit.Room temperature is empty
Gas inputs the preceding deaerating plant 9 that passes through in chamber ontology by normal temperature air input unit 8 and carries out deoxygenation to normal temperature air.Experiment
Temperature sensor 5 is additionally provided in case ontology.Humidity sensor is additionally provided in chamber ontology.It is additionally provided with power control dress
It puts, the heating power of Infrared High-Power heating unit is controlled by power control device.Chamber ontology is also associated with vacuum pump
10.Quenching apparatus is connected to Test section by a flow valve 2.It is additionally provided with warning device 3.Warning device 3 is LED light.Also
Control device 4 is provided with, control device includes control device, control device and temperature sensor, humidity sensor, flow valve
2nd, warning device 3 and air delivery arrangement are connect with vacuum pump.
Carry out high and low temperature impact test when, heated by control device set temperature and to environment in chamber or
Cooling.When turning low temperature from high temperature, normal temperature air is passed through, is then vacuumized, be finally passed through cooling medium.Turn height from low temperature
Wen Shi is passed through normal temperature air, is then vacuumized, finally heated.Control device is additionally provided with memory, in memory
Record valve flow size, heating power size and temperature change size, time should be related to master controller is according to corresponding pass
System and temperature sensor carry out automatically controlling.Drier is additionally provided in chamber, for ensureing the humidity in zone of reasonableness.
By being passed through normal temperature air, when carrying out high/low temperature switching, significant component of energy can be saved.
The foregoing is merely the preferred embodiment of the application, not to limit the application, it is all in spirit herein and
Within principle, any modification, equivalent replacement, improvement and so on should be included within the protection domain of the application.
