What is a two-box thermal shock testing machine?
In today's era of rapid technological development, product reliability and durability testing has become increasingly important. As an important environmental testing equipment, the two-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 two-box thermal shock testing machine
The two-box thermal shock testing machine is a testing equipment used to simulate the performance of products in extreme temperature change environments. It tests the product's ability to withstand sudden temperature changes by quickly switching between high and low temperature environments. This kind of equipment usually consists of a high temperature chamber, a low temperature chamber and a sample transfer mechanism, which can complete temperature conversion in a very short time.
2. Working principle
The working principle of the two-box thermal shock testing machine is as follows:
| steps | Operation | time |
|---|---|---|
| 1 | Put the sample into the high temperature box | Preset time (e.g. 30 minutes) |
| 2 | Quick transfer to cryogenic chamber | ≤15 seconds |
| 3 | Samples are kept in a cryogenic chamber | Preset time (e.g. 30 minutes) |
| 4 | Quick transfer back to high temperature chamber | ≤15 seconds |
This cycle can be repeated hundreds or even thousands of times to simulate the temperature shock a product may encounter during long-term use.
3. Main application areas
Two-box thermal shock testing machines are widely used in many industries:
| Industry | test subject | Test purpose |
|---|---|---|
| Electronic appliances | Circuit boards, chips, batteries | Testing performance stability under sudden temperature changes |
| automobile manufacturing | Auto parts, instrument panels | Proven reliability under extreme temperature conditions |
| Aerospace | Avionics | Ensure normal operation in extreme temperature environments at high altitudes |
| Materials Science | New composite materials | Study the thermal expansion and contraction properties of materials |
4. Comparison of popular models in the market
According to recent market research, the following is a comparison of popular two-box hot and cold shock testing machine models in 2023:
