In recent years, with the rapid development of electronics, automobiles, aerospace and other industries, the two-box thermal shock testing machine has received widespread attention as an important testing equipment. This article will give you a detailed introduction to the definition, principle, application and market data of the two-box hot and cold shock testing machine based on the hot topics and hot content on the entire network in the past 10 days.
1. Definition of two-box thermal shock testing machine
The two-box hot and cold shock testing machine is a testing equipment used to simulate extreme temperature changes. It is mainly used to test the performance stability of products under rapid temperature changes. Its core feature is to achieve rapid temperature switching through two independent temperature zones (high temperature box and low temperature box), simulating the temperature shock that products may encounter in nature or use environments.
2. Working principle and structure
The two-box hot and cold shock testing machine quickly moves the test sample between two temperature zones through a mechanical transmission system to achieve sudden temperature changes. Here’s a comparison of its core structure and workflow:
| components | Function description |
|---|---|
| High temperature box | Provides high temperature environment from +60°C to +200°C |
| cryogenic chamber | Provides low temperature environment from -70°C to 0°C |
| transmission mechanism | Achieve sample temperature zone switching within 10 seconds |
| control system | Precisely control temperature, time and number of cycles |
