What is a horizontal low temperature testing machine?
In today's era of rapid technological development, low-temperature testing machines, as an important environmental testing equipment, are widely used in aerospace, electronic appliances, automobile manufacturing 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 readers fully understand this equipment.
1. Definition of horizontal low temperature testing machine
The horizontal low-temperature testing machine is a testing equipment used to simulate low-temperature environments. Its structure is designed to be placed horizontally (horizontal) and is suitable for low-temperature performance testing of large or heavy samples. It lowers the temperature in the test chamber to the set value through the refrigeration system and keeps it stable to test the tolerance and reliability of the sample under low temperature conditions.
2. Working principle
The working principle of the horizontal low-temperature testing machine mainly includes the following steps:
1.Refrigeration system: Achieve low-temperature environment through compressor, condenser, evaporator and other components.
2.temperature control: Adopt PID control technology to accurately adjust the temperature inside the box.
3.data logging: Monitor temperature changes in real time through sensors and record test data.
3. Application scenarios
Horizontal low temperature testing machines are widely used in the following fields:
| field | Application scenarios |
|---|---|
| Aerospace | Test the performance of aircraft components in extremely cold environments |
| Electronic appliances | Test the working stability of electronic products at low temperatures |
| automobile manufacturing | Verify the durability of car batteries, rubber parts, etc. in low temperature environments |
| Materials Science | Study the physical and chemical properties of materials at low temperatures |
4. Comparison of popular models in the market
The following is a comparison of the popular horizontal low-temperature testing machine models and their main parameters on the market recently:
| Model | temperature range | Volume (L) | Refrigeration method | Brand |
|---|---|---|---|---|
