What is a three-box thermal shock testing machine?
In today's era of rapid technological development, product quality and reliability testing have become increasingly important. As an important environmental testing equipment, the three-box thermal shock testing machine is widely used in electronics, automobiles, aerospace and other fields. This article will introduce in detail the definition, working principle, application scenarios and comparison of popular models on the market to help you fully understand this equipment.
1. Definition of three-box thermal shock testing machine
The three-box hot and cold shock testing machine is a testing equipment used to simulate extreme temperature changes. By quickly switching three boxes of high temperature, low temperature and normal temperature, it can test the performance and reliability of products under rapid changes in temperature. Compared with the traditional two-box thermal shock testing machine, the three-box design is more efficient and can achieve faster temperature conversion rates.
2. Working principle
The working principle of the three-box thermal shock testing machine is based on the collaborative work of three independent boxes:
| cabinet | Function |
|---|---|
| High temperature box | Provide high temperature environment (usually up to 150°C and above) |
| cryogenic chamber | Provide low temperature environment (usually as low as -70°C) |
| test box | Place the test sample to achieve rapid temperature switching |
During the test, the sample moved rapidly between the three boxes through a robotic arm or lifting mechanism, simulating an environment with rapid temperature changes.
3. Application scenarios
Three-box thermal shock testing machine is widely used in the following fields:
| Industry | Application scenarios |
|---|---|
| Electronic appliances | Test the reliability of circuit boards, chips, displays, etc. under temperature shock |
| automobile manufacturing | Test performance of auto parts, batteries, and more in extreme temperatures |
| Aerospace | Test the adaptability of spacecraft components in low-temperature environments at high altitudes and high-temperature environments on the ground |
| Materials Science | Study the changes in physical and chemical properties of new materials under sudden temperature changes |
4. Comparison of popular models in the market
The following is a comparison of the popular three-box thermal shock testing machine models on the market recently:
| brand | Model | temperature range | conversion time | Volume |
