Overview
The structure of the three box cold and hot shock test chamber system can be divided into three parts: high temperature tank (preheating zone), low temperature tank (pre cooling zone), and test tank (room temperature zone). The independent tank area air path switching method can introduce the cold and heat of the low temperature tank and high temperature tank or room temperature air into the test tank, so that the test samples in the test tank can be quickly converted between low temperature, high temperature, and room temperature environments, and the test samples do not move during the test process. This test chamber is suitable for assessing the ability of complete machine products, components, parts, materials, etc. to withstand rapid temperature changes. The temperature shock test is used to evaluate the chemical changes or physical damage caused by thermal expansion and contraction of the test sample in the shortest possible time, and can understand the impact of temperature changes on the test sample once or continuously multiple times. The main parameters that affect the temperature change test are the high and low temperature values within the temperature change range, the holding time of the test sample at high and low temperatures, and the number of cycles of the test. The thermal shock test chamber is an essential testing equipment for the metal, plastic, rubber, electronic and other material industries.

Product Introduction
The structure of the three box cold and hot shock test chamber system can be divided into three parts: high temperature tank (preheating zone), low temperature tank (pre cooling zone), and test tank (room temperature zone). The independent tank area air path switching method can introduce the cold and heat of the low temperature tank and high temperature tank or room temperature air into the test tank, so that the test samples in the test tank can be quickly converted between low temperature, high temperature, and room temperature environments, and the test samples do not move during the test process. This test chamber is suitable for assessing the ability of complete machine products, components, parts, materials, etc. to withstand rapid temperature changes. The temperature shock test is used to evaluate the chemical changes or physical damage caused by thermal expansion and contraction of the test sample in the shortest possible time, and can understand the impact of temperature changes on the test sample once or continuously multiple times. The main parameters that affect the temperature change test are the high and low temperature values within the temperature change range, the holding time of the test sample at high and low temperatures, and the number of cycles of the test. The thermal shock test chamber is an essential testing equipment for the metal, plastic, rubber, electronic and other material industries.
Working principle
The three box cold and hot shock test chamber is equipped with three parts: low temperature zone, high temperature zone, and test zone. The three zones are independent, and the test products do not need to be moved between the three chambers through air doors. When the chamber is impacted at room temperature, the ambient temperature is introduced into the test space through a blower, eliminating heat or cold from the test space. At the same time, the air doors of the high and low temperature slots are closed. When the chamber is impacted at low temperature, the air doors of the high and low temperature slots are closed, and the pre stored cold is instantly introduced into the test chamber. When the chamber is impacted at high temperature, the air doors of the low and normal temperature slots are closed, and the high temperature slot is connected to the test chamber, instantly introducing the pre stored heat into the test chamber to achieve.
