Power supply information |
1)AC 380V three phases with R,S,T, N+ protective grounding; voltage fluctuation range 10% 2)Frequency fluctuation range:50±0.5HZ; 3)Power supply method: TN-S or TT method 4)Grounding resistance of protection ground wire<4Ω 5)User should equip with relevant capacity air switch or dynamic switch on the installation site, and the switch must control this machine only. When the electrified test sample is put in the test chamber, the power of the test sample should be connected with extra power, don’t use the power of this machine; |
Performance Index |
|
Function requirement |
1.(air) cooling / heating in the chamber space 2.The test chamber temperature reach to the set temperature according to the temperature; 3.three areas: heat storage area; cold storage area and test area; 4.The three test areas are independent from each other, switch over the temperature through air door; |
Use environment requirement |
ambient temperature is 0~+35℃,relative humidity is≤85% |
Executive standard and test condition |
GJB150.5A-2009 temperature shock test GB/2423.13-2002 temperature shock test GJB360B-2009 temperature shock test GB2423.1-2008/IEC6008-2-1-2007 Electronic Electrician Product Environmental Test Part 2:test method Test A: low temperature GBT 2423.2-2008 Electronic Electrician Product Environmental Test Part 2:test method Test B: high temperature GBT 10589-2008 low temperature test chamber technical condition GBT 11158-2008 high temperature test chamber technical condition |
Temperature range |
|
Temperature range |
high temperature zone: RT~170℃ low temperature zone: RT~ -75℃ test area: -65~ 150℃ |
Temperature shock range |
high temperature: 60℃~ 150℃ low temperature: -10℃ ~ -65℃ R.T.: room temperature |
Control accuracy |
temperature resolution: 0.1℃ temperature fluctuation: ±1℃ distribution uniformity: ±2.0℃ temperature deviation: ±1℃ |
Heating/cooling rate |
heating time in heating area:R.T.~+170℃, about 30 min; cooling time in cooling area: R.T.~ -75℃, about 80 min; |
Temperature recovery time |
temperature recover time in test zone: 5 minutes. shock process (see as below) The red curve is shocking in test area; T he blue curve is cold storage in low temperature zone The green curve is heat storage in high temperature zone; |
Note: Steel heat capacity ≤35kg/m3 ; |
|
Note: The data above is under the condition of environment temperature is +25℃,and R.H. is ≤85%,no test sample in the chamber; |

Structure Feature |
|
Chamber structure |
internal material: 304# stainless steel with 1.2 mm thick external material: 304# stainless steel with 1.0mm thick heat preservation material: polyurethane foam rubber + glass cellucotton 150mm thick |
Chamber door |
single open door anti-explosion holder |
Air conditioning channel |
inside high temperature / low temperature air space, recirculating wind channel and stainless steel cycle fan, through the switchover of ventilation door, the heat and cooling volume will be out uniformly from the inner ventilation channel, let the storaged temperature from the high and low temperature area diffuses to the test area, which could reach the purpose of temperature rapidly alternated and inner temperature uniformly distributed. |
Lead test hole |
Φ50mm,enclosed with relative temperature preservation and heat insulation parts ,the special seal softplug. |
Control panel |
South Korea SAMWON TEMP2700S LCD touch screen programmable controller from Japan, main power switch, running indicate light, abnormal indicate light, end indicate light, defrost indicate light, power indicate light, RS-232 communicate interface |
Low temperature area machine room |
evaporimeter, circulating fan, drainage device, cold storage piece, heater, circulating wind wheel, volute |
High temperature area machine room |
circulating fan, pressure balance port, heat storage piece, heater, circulating wind wheel, volute |
Power distribution control cabinet |
general power disconnector, controller, switch panel, heat rejection fan, overheat protector, cylinder, pressure protector, liquid storage pot, water –cooled condenser, refrigerating unit |
Heating system |
adopt the scale heat rejection heating pipe P.I.D. control the heating so let the temperature gets the balance |
Cooling system |
use water-cooled heat exchanger |
Cooling tower |
use cooling water tower from Liangji, Taiwan, water circulation heat dissipation use, flow rate is 8T/H ( selective item) |
Transportation method |
Whole machine |
Test specimen frame |
SUS #304 stainless steel grille type shelf , 2 pieces ( loading ≦30kg/piece) adjustable distance 40mm |
Working mode |
Pre-cooling area, preheating area, test area independently from each other, through wind door to switchover the three chambers, do not need to move test specimen, when ambient temperature shocking, through fan to lead-in the ambient temperature to test room, exhaust the heating volume or cooling volume from the testing space, at the same time, close the high/low temperature area wind door; when impact low temperature testing, high and ambient temperature area wind door are closed, high temperature and test chamber are connected with each other which will lead in the pre-cooling volume to the test chamber; when impact high temperature, low temperature and ambient wind door are closed, high temperature area and test chambers are connected with each other, so that reach the purpose of temperature rapid alternated |
