Electronic Shock Simulate Environmental Test Chamber Hot and Cold Temperature

Electronic Shock Simulate Environmental Test Chamber Hot and Cold Temperature

1. Description:

Electronic Hot and Cold Temperature Shock Simulate Test Machine is used to test the material structure or composite material, in an instant by the level very high temperatures and very low temperature environment can tolerate continuous, whereby chemical changes in the most short time to test its thermal expansion and contraction caused by physical damage .Entire machine (or parts), electrical appliances, equipment, materials, coating, coating and other appropriate climate for accelerated test

A thermal shock chambers structural forms: thermal shock chambers chamber using integrated forms of composite structure, both located in the upper chamber by a high-temperature tank, located in the lower portion of the cryogenic tank, located in the rear of the cabinet and the refrigeration unit is located after the left side of the electrical control panel composed of cabinet (system). In this way small cabinet footprint, compact structure, beautiful appearance, refrigeration units placed in a separate unit housing, in order to reduce vibration refrigeration unit is running, the impact of noise on the chamber
B thermal shock chambers outer box material: high-quality cold-rolled steel sheet, the surface for electrostatic spraying.
C thermal shock chambers inside walls Material: SUS304 stainless steel, corrosion-resistant, easy to clean, nice.
D insulation materials: high-quality ultra-fine glass fiber cotton, imported nonflammable PU.
E sample holder: static stainless steel sample holder.
F window: On the box (hot box) opened the door to a 350 × 250mm electric moisture barrier coating temperature observation window.

2. Specifications of Electronic Hot and Cold Temperature Shock Simulate Test Machine:

3.Notes

. If the high-temp exposure range lower limit + 60°C is required or the low temp exposure range lower limit -60°C, please select the “ambient-temperature exposure” option

. If the temp fluctuation need to below ±1.8°C please select the “Low temp fluctuation package”

. Temperature heat-up/pull down time are applicable only during independent chamber operation

. If the automatically operated sliding door required, please select the “Automatically door package”

. Air-cooled condenser / Water-cooled condenser both available

. Apply on water-cooled condenser only

4.Feature

.   The product appearance, reasonable structure, advanced technology, sophisticated material, simple and convenient operating performance and reliable equipment performance.
.   The equipment is divided into hot boxes, cold boxes, three-part test box, picking off the unique structure of the heat storage and heat storage effect of the test analytes completely still, apply hot and cold air path switching manner of hot and cold temperature into the test region to thermal shock testing purposes.
.   Using the most advanced measuring device, the controller uses a large color LCD touch man-machine interactive LCD man-machine interface controller, simple operation, easy to learn, reliable, in English full system operating conditions, execution Setup program curves.
.    with 96 test specifications set independently, the impact time 999 hours and 59 minutes, cycle times can be set from 1 to 999 can be realized refrigerator automatic operation, to achieve the maximum degree of automation, reduce operator workload, in any ﹑ automatic start time running stop working;

5.Air conditioning system

.   the air control: forced ventilation circulation, balance thermostat method (BTC). This method not only refers to the case of the cooling system for continuous operation, the control system according to the temperature set point of the heater to control the output of the results by automatically calculating PID output, and ultimately achieve a dynamic equilibrium.
.   air circulating means: built between the air circulation fan duct and the long axis of stainless steel, the use of energy efficient refrigerators and regulation system, by effective and efficient heat exchange ventilator, to achieve the purpose of the temperature change. By adjustable air outlet adjusting bolt, thereby significantly improving the chamber temperature uniformity;
.   the air cooling method: multi-stage diaphragm air heat exchanger.
.   air heating: Watkins quality nickel chrome electric heater.
