LIYI Stand Alone 3 Zone Temperature Cycling Chamber Electronic
Products Test
Machine introduction:
Programmable 3- Zone Temperature Cycling Cool and Heat Thermal
Shock Testing Chamber for Electronic Products makes the product
under low and high temperature, and accelerates the failure caused
by repeated temperature changes under normal operating conditions
of items.During cold and hot shock tests, the transition between
extreme temperatures was very rapid, exceeding 15℃ per
minute.Alternatively, the temperature cycle uses a slower rate of
high and low temperature change, exceeding 5℃ per minute.

Application objects, including metal, plastic, rubber, electronics
and other materials can be used as a basis to improve their
products or reference.
Remark: We can achieve 1000cycles defrosting once, it is very
ideal, the shorter the defrosting interval, the worse the
airtightness of the device!

the internal cooling system clean and reliable. water tray located at the bottom of the compressor to ensure
condensate water drain through pipe freely at the rear of the
chamber. |
Since the cold chamber need huge cooling capacity for shocking, the
chamber’s cooling mode is often designed as air-cooled or
water-cooled.
Air-cooled type need installation environment:
The room must be equipped with exhauster and air conditioner to
make sure heat dissipation timely.
It’s applied to small power products and cool areas.
Water-cooled type need installation conditions:
The customer must prepare water pipe and water tower (located
outside) accordingly.
The water must be pure, or it will block the pipes and result in
some maintenance trouble with time going.
It’s often applied to large system with the features of better heat
dissipation, longer service time, low noise but slightly higher
price if count the fee of water tower and water pipes.
