1. Product introduction: Main functions and advantages of the equipment:

1.1 Product Overview

The Hot oil impact test chamber can be used to determine the impact of temperature cycling changes on electronic products, components, materials, etc. in ultra-High and ultra-low temperature oil tanks, as well as changes in product performance.

The hot oil impact test chamber adopts a relatively reasonable structure and stable and reliable control method, making it aesthetically pleasing, easy to operate, safe, and with high humidity control accuracy. It is an ideal equipment for conducting low humidity tests, constant temperature and humidity tests, and alternating humidity tests.

1.2 Product Advantages and Technical Features

1.2.1 Utilize a multi-channel, environmentally friendly and energy-saving (low-noise) mechanical compression refrigeration system.

All materials, parts, components, raw materials, etc. of the hot oil impact test chamber, whether domestic or imported, are made of environmentally friendly products; Based on the characteristics of mechanical compression refrigeration, a two-stage multi-channel main and bypass system is adopted. The multi-channel main and bypass can be adaptively selected and activated according to different working conditions. The entire control is automatically implemented by an intelligent control system according to the working conditions, changing the traditional way of using a temperature controller to control the heater to offset the cooling capacity to control the cooling capacity. So as to achieve energy-saving effect, not only does the energy consumption account for only 80% of similar products. It also reduces the operating load of the refrigeration compressor, reduces equipment vibration and noise, and improves control accuracy. To achieve better energy-saving effects, frequency conversion technology is adopted to adapt the refrigeration output of the refrigeration compressor to various temperature change rate requirements in the laboratory, while controlling the power loss during use to achieve energy-saving effects. Use sound-absorbing and silencing methods in different parts of the entire structure and mechanical working process to reduce the overall noise of the equipment.

1.2.2. Independently developed multi-channel and multi-stage throttling system (refrigeration system).

The refrigeration system of this equipment is designed with different capillary main paths and bypass paths according to different operating conditions. The capillary throttling system is automatically controlled and adjusted by the intelligent communication control system based on the operating conditions to ensure that the flow rate can be adjusted, achieving the purpose of temperature change. Moreover, the temperature field changes uniformly and the temperature fluctuation is minimal.

1.2.3. Apply a broadband compression balance temperature control system to achieve rapid temperature control through a fast convergence PID adaptive algorithm.

By using a temperature mixing chamber, a static pressure chamber, and a forced air duct system with centrifugal blades, sufficient exchange of cold and heat is ensured, and air is evenly supplied through the top orifice plate to each space in the working room (experimental area) to achieve temperature uniformity; To achieve rapid temperature convergence

1.2.4 Implement remote visual control.

The device is equipped with a human-machine management interface and a touch mode automation control system to achieve automatic control; Simultaneously, connect to remote computers through RS485 communication interface to achieve network management and remote monitoring. The entire system is controlled and managed through a graphical interface, which is simple and fast, with automatic fault prompts. The graphical prompts are energy-saving and provide solutions to guide users in quickly troubleshooting.
