The hot and cold shock box is divided into three-box type and two-box type according to the test requirements and test standards.
The difference lies in the test method and internal structure
.
The three-box type is divided into a cold storage room, a heat storage room and a test room, and the product is placed in the test room during the test
.
The two-box type is divided into a high temperature room and a low temperature room.
The high and low temperature switching is realized by the movement of the basket by the motor.
The product is placed in the basket and moves with the basket
.
1.
The difference between the characteristics The two-box cold and hot shock box and the three-box cold and hot shock box performance characteristics: both samples are quickly put into a pre-cooled low-temperature chamber or a pre-heated high-temperature chamber for testing.
The impact box can be used as both a thermal shock test box and a separate high temperature box or a separate low temperature box, so the temperature change speed is fast; the three-box dynamic temperature shock test box is composed of a high temperature chamber, a low temperature chamber, a test chamber and two chambers.
It is composed of a test sample basket that moves in the chamber, a refrigeration system, a heating system and a control system
.
2.
Differences in structure The two-box type hot and cold impact box is compact in structure and small in size; the two-box type is divided into a high-temperature chamber and a low-temperature chamber.
The high and low temperature switching is realized by the movement of the basket driven by the motor.
The product is placed in the basket.
Moves with the basket
.
The three-box type has a room temperature box, which is convenient for testing and taking samples; it is divided into three parts: high temperature area, low temperature area and test area.
It adopts du te thermal insulation structure and heat storage and cold storage effect, and adopts the switching method of hot and cold air paths.
Introduced into the sample, and do the thermal shock test
