What is a temperature cycle hot and cold shock testing machine?
In the fields of industrial production and scientific research, the temperature cycle hot and cold shock testing machine is an important environmental testing equipment used to simulate the performance of products under extreme temperature changes. This article will introduce in detail its definition, working principle, application scenarios, and technical progress related to it in recent hot topics.
1. Definition of temperature cycle hot and cold shock testing machine
The temperature cycle hot and cold shock testing machine is a device that tests the reliability, stability and durability of materials, components or complete products under conditions of rapid temperature changes by rapidly switching between high and low temperature environments. Its core function is to simulate extreme temperature changes that may be encountered in nature or the use environment, such as day and night temperature differences, high altitude low temperatures or high temperature sudden drops, etc.
2. Working principle and structure
The device typically consists of the following core components:
| components | Function |
|---|---|
| High temperature box | Provide high temperature environment (up to +150°C or above) |
| cryogenic chamber | Provide low temperature environment (as low as -70°C) |
| conversion system | Quickly switch test samples between high and low temperature chambers |
| control system | Set temperature curve, cycle number and time |
When working, the sample will be alternately exposed to high and low temperature environments within a preset time. The switching time can be as short as a few seconds to simulate severe temperature shock.
3. Application scenarios
This equipment is widely used in the following fields:
| Industry | Test purpose |
|---|---|
| Electronic appliances | Test the temperature resistance of circuit boards and chips |
| automobile manufacturing | Verify the reliability of components in extreme climates |
| Aerospace | Simulate temperature changes aloft or in space |
| Materials research | Study parameters such as thermal expansion coefficient of new materials |
4. Recent hot topics and technological progress
According to the hot content on the entire network in the past 10 days, topics related to temperature cycle hot and cold shock testing machines mainly focus on the following aspects:
| hot topics | Content summary |
