With the upgrading of national industries, there are mandatory requirements for products in all walks of life. Especially in the new energy vehicles, motors, electronic controls, batteries, and electronic aerospace industries, Chinese companies are guided to advance into technological and cutting-edge products. This requires continuous verification of the reliability of various simulation tests on related materials, components, functional units, and systems. Correspondingly, the use of product testing equipment will increase significantly, and at the same time, it has also spawned reforms in testing processes. In order to simulate a wider temperature range, rapid temperature changes, higher temperature stability, and ensure the repeatability of experimental conditions, a higher standard temperature control system is required. The liquid energy temperature function system is a rapid refrigeration testing device produced under this environment.

Introduction of Dawoxi Temp Controller

The high and low temperature liquid cooling tester is a test device used to simulate extreme temperature environments and quickly and accurately control the temperature of the equipment under test (such as electronic components, batteries, chips, automotive parts, etc.). It combines liquid cooling technology and high and low temperature control systems, and can achieve rapid temperature rise and fall, high-precision temperature control, and long-term stability testing. It is widely used in scientific research, industrial production, and quality inspection.

 Core composition and working principle

1. Liquid cooling circulation system

Use a circulating pump to drive the coolant (such as ethylene glycol aqueous solution, silicone oil or special refrigerant) through the device under test or test chamber, and use the high heat capacity and high thermal conductivity of the liquid to achieve efficient heat exchange.

Liquid cooling is more efficient than traditional air cooling and is suitable for scenarios with high power density or requiring rapid temperature changes.

2. Temperature control module

Refrigeration system: uses compressors, expansion valves, etc. to achieve low temperatures (e.g. -70°C to -40°C).

Heating system: high temperature (e.g. +100°C to +200°C, or even higher) is achieved through electric heaters.

PID control algorithm: **Adjust the cooling/heating power to ensure small temperature fluctuations (e.g. within ±0.5℃).

3. Control system

Touch screen or software interface, supports customized temperature curve (step change, cycle test, program controllable test, fixed value test, etc.).

Real-time monitoring of temperature, flow, pressure and other parameters, with alarm and protection functions (such as over-temperature, over-current, low liquid level).

4. External interface

Adapt to different test fixtures, support multi-channel fluid connection, and be compatible with devices of various sizes and shapes

Key performance parameters

Temperature range: Typical range -40 ℃ to +85 ℃, some devices can reach -90 ℃ to +250 ℃.

Cooling capacity: from several hundred watts to several tens of kilowatts (such as 10kW , 50kW , etc.) according to demand.

Flow control: adjustable flow range (such as 5~50L/min ).

Response speed: Heating and cooling rate can reach 5~10 ℃ /min

Precision control: temperature stability ± 0.1~0.5 ℃, flow fluctuation within ± 0.2L , pressure fluctuation accuracy ± 0.1bar.

Core advantages
