Product Details


Applicable to the new generation of energy battery pack, which can effectively test the Chao of the battery pack, strong environmental adaptability, improve the safety and reliability of the whole vehicle, and ensure the good operation of the vehicle in a variety of complex environments.

The products are widely used for limit performance test of motor and battery pack, rapid temperature rise and fall thermal shock test, and comprehensive environmental adaptability evaluation test.

The temperature variation range is usually from – 40 to 100 degrees (which can be extended to 150 degrees). While controlling the temperature, you can also choose to control the flow or pressure; it is equipped with a strong circulating pump to ensure the transmission of high viscosity liquid; frequency conversion regulation or proportional regulation valve is used to control the flow output to achieve high-precision control, and the total range can be adjusted by 5% ~ 100%.


The tested object is connected to a test platform adapter; The parts are cooled and heated by glycol aqueous solution; The test component needs to experience a specific temperature change curve and record the temperature change.

On test benches in the automotive industry, high-precision temperature control systems are used for material and component testing, enabling precise adjustment and rapid temperature changes. Only precise temperature management can provide reliable and repeatable results. In addition to the temperature of the medium, the temperature control system can also accurately control the flow rate and working pressure. Temperature control systems are mainly used in two ways: to simulate external environmental conditions in a climate chamber or to replace internal systems, such as the cooling circuit of an engine.

Closed circulation
The whole system is a fully closed system, there will be no oil mist at high temperature, low temperature does not
absorb water in the air, the system in operation will not because of high temperature pressure rise, low temperature
automatically add heat conduction medium.
