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.two areas: high temperature area; low temperature area; 4.The two areas are independent from each other, switch over the temperature through swinging stage; |
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: 50℃~ 150℃ low temperature: -10℃ ~ -65℃ |
Control accuracy |
temperature resolution: 0.1℃ temperature fluctuation: ±1℃ distribution uniformity: ≤2.5%℃ temperature deviation: ±1℃ |
Temperature recovery time |
shocking time within 10 S 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; |
Cold storage time |
RT→-75℃ ≤ 80min |
Heat storage time |
RT→170℃ ≤ 35min |
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 |
both high temperature chamber and low temperature chamber are single open door anti-explosion holder |
Air conditioning channel |
inside high temperature / low temperature air space, loops wind channel and stainless steel cycle fan, through the switchover of swinging stage, the swinging stage is pushed by the cylinder between high temperature area and low temperature area, which could reach the purpose of temperature rapidly alternated and inner temperature uniformly distributed. |
Control panel |
South Korea SAMWON TEMP2700S LCD touch screen programmable controller from Japan, initial position change over switch of swinging stage, 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, air–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 air-cooled heat exchanger |
Transportation method |
whole machine |
Test specimen frame |
SUS #304 stainless steel grille type shelf , 2 pieces ( loading ≦30kg/piece) adjustable distance 40mm |
Working principle |
connect swinging stage with punching halftone, the upper and lower part include heat preservation and seal material, use cylinder to push it, steel wire to lifting. Install fixed pulley on the top and put the specimen in the swinging stage, then lift and push the swinging stage based on the output order from controller, which will reach temperature alternated rapidly for long period stable running |
