1. Definition of hot and cold shock chamber testing machine
The hot and cold shock chamber testing machine is a testing equipment that simulates extreme temperature changes and is used to test the performance and reliability of products in environments with rapid temperature changes. It evaluates the weather resistance and durability of the product by quickly switching between high and low temperature environments to simulate the temperature shock that the product may encounter in actual use.
2. Working principle of hot and cold shock chamber testing machine
The hot and cold shock chamber testing machine implements temperature shock testing through the following steps:
| steps | Description |
|---|---|
| 1. Warm up | Place the test sample in the high temperature box to reach the preset high temperature value. |
| 2. Quick conversion | Rapidly transfer samples to the cryochamber via mechanical or pneumatic systems. |
| 3. Cool down | The sample is kept in the cryobox for a period of time to reach a preset low temperature value. |
| 4. Loop test | Repeat the above steps for multiple temperature shock cycles. |
