What is a programmable thermal shock testing machine?
In today's rapidly developing technological and industrial fields, product quality and reliability testing have become increasingly important. As an important environmental testing equipment, the programmable thermal shock testing machine is widely used in electronics, automobiles, aerospace and other industries. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market of programmable thermal shock testing machines.
1. Definition of programmable thermal shock testing machine
The programmable thermal shock testing machine is a testing equipment that simulates extreme temperature changes and is used to test the performance and reliability of products under rapid temperature changes. It simulates the temperature shock that a product may encounter in actual use by quickly switching between high and low temperature environments to evaluate the durability and stability of the product.
2. Working principle
Programmable thermal shock testing machines usually consist of a high temperature chamber, a low temperature chamber and a test chamber. During the test, the sample rapidly switches between high and low temperature environments, and the temperature change rate can reach tens of degrees Celsius per minute. The equipment ensures the accuracy and repeatability of temperature changes through a precise control system.
| components | Function description |
|---|---|
| High temperature box | Provides high temperature environments, typically ranging from +60°C to +200°C |
| cryogenic chamber | Provides low temperature environments, typically ranging from -40°C to -70°C |
| test box | Place the test sample to achieve rapid temperature switching |
| control system | Precisely control the rate and duration of temperature changes |
3. Application fields
Programmable thermal shock testing machines are widely used in many industries. The following are its main application areas:
| Industry | Application scenarios |
