The working principle of the three-box (high and low temperature impact test box) cold and hot impact test box

The working principle of the three-box cold and hot shock test box

One, three box type cold and hot shock box adopts upper, middle and lower box structure, the upper part is high temperature box, the lower part is low temperature box, the middle box is the test box, the low temperature system is located on the left of the studio, and the electrical control cabinet On the right side of the test box, easy to operate.

Two, three box type cold and hot shock test box function: it is designed and manufactured according to user requirements, suitable for high and low temperature impact test and high temperature or high temperature or low temperature impact test of the complete machine and parts of aviation, aerospace, military, ship, electrical, electronic Storage and testing in low temperature environment. For users to make corresponding climate environment accelerated tests on the whole machine (or parts), electrical appliances, instruments, materials, coatings, coatings, etc., in order to evaluate the test product or test product test behavior.

Three, three box type cold and hot shock test box main technical indicators: * temperature range: high temperature box: +60 ℃ ~ 200 ℃; * low temperature box: 0 ℃ ~ -70 ℃; * temperature fluctuation: ± 0.5 ℃; * temperature Uniformity: ± 2 ℃; * Rate of heating: ≤5 ℃ / min; (overall process average) * Cooling rate: ≤5 ℃ / min ;; (overall process average) * Pre-cooling lower limit temperature: ≤-70 ℃; * Shock temperature: + 150 ～ -60 ℃; * Working room size: 400 × 400 × 400mm; (Depth × Width × Height) * Sample holder size: 150 × 150mm; * Temperature recovery time: 5min; * Sample holder conversion time: ≤10s; * Impact method: move up and down basket type or flip type * Power supply: 380V ± 10 ﹪ 50Hz
