High and low temprature thermal shock testing chamber

3-Zone Thermal Shock Chambers Working Principle:

The three-zone type thermal shock test chamber. Sample is placed in the test chamber, more extreme temperature than test temperature can be set in high-temperature chamber and low-temperature chamber. During low temperature test, cold chamber door open, and low-temperature chamber working together with test chamber. When converted into high-temperature test, cold chamber door closed, hot chamber door are opened, and test chamber working together with high-temperature chamber.

Conversion of mechanical action (transferring from high temperature to low temperature or low temperature to high temperature) can be completed in less than 1 second, and the temperature can be quickly stabilized.

During the whole test, test sample is no need to be moved, and without any human intervention.

Below are differences between 3-zone and 2-zone thermal shock chamber:

3-zone thermal shock chamber:

three chamber in total: test space, high temp. chamber and low temp. chamber;

Advantage: slight limitation for test sample’s weight, the test sample keep still, this can reduce the impact to samples by moving it, can be used for on-load testing.

Compared with 2-zone type, relatively low failure rate, low cost.

Disadvantage: long conversion time

2-zone thermal shock chamber:

only two chambers: high temp. Chamber and low temp. chamber

Advantage: short conversion time, smaller space needed

Disadvantage: test sample moving. test samples’ size is limited by the basket size

1. Introduction of thermal shock chamber:

3-Zone Thermal Shock Chambers Application:

Such chambers heretofore known include one comprising a test area for the test sample, a high-temperature air conditioning unit having gas outlet and intake adapted to communicate with the test area, an outside air supplying unit having air outlet and inlet adapted to communicate with the test area, and a low-temperature air conditioning unit having gas outlet and intake adapted to communicate with the test area.
The thermal shock chamber of this type is provided with three dampers, i.e., one for opening or closing the gas outlet and intake of the high-temperature air conditioning unit, another for the air outlet and inlet of the outside air supplying unit, and another for the gas outlet and intake of the low-temperature air conditioning unit.

1.3 KOMEG offers several configurations of thermal shock chambers capable of meeting a wide variety of testing needs.
Vertical, two zone chamber has hot and cold zones that can be controlled independently.
Horizontal, three zone thermal shock chamber utilizes controlled areas for hot, ambient and cold temperatures.
Double duty thermal shock chambers from KOMEG are designed with hot zones above and below the cold zone and a two compartment product carrier that simultaneously moves products between the hot and cold zones.
