Advantages of Proportional Valve Control
Traditional liquid-cooled test equipment usually uses variable frequency pumps or throttle valves to adjust flow, which has problems such as slow response speed and limited adjustment accuracy. Our liquid-cooled test equipment uses proportional valve control, which has the following three advantages compared to traditional solutions:
1. Accurate Flow Control
Using variable frequency flow control, the flow output value can be set arbitrarily within the specified range, and the minimum control accuracy is +0.1L/min.
2.Multi-channel Independent Control
The number of output channels of Zhongzhi proportional valve high temperature liquid-cooled testing machine supports 2 channels, 3 channels, 4 channels, 8 channels, and 16 channels, and can realize multi-channel coolant flow adjustment according to testing needs.
3. Programmable Flow Control
The equipment supports presetting the coolant flow rate for each test stage and achieves precise adjustment through the proportional valve.
Product Applications
Zhongzhi's proportional valve high-temperature liquid-cooled testing machine can perform thermal management tests on various liquid-cooled products, including new energy vehicle motors, motor controllers, and on-board chargers. The main test items are as follows:
1. High-Temperature Fatigue Test
Verifies the thermal management performance of the tested liquid-cooled components by precisely controlling the coolant temperature and flow rate.
2. Pressure Drop and Flow Resistance Test
Precisely measures the pressure loss and flow resistance of the coolant as it flows through the internal channels of the tested component, verifying the rationality of the flow channel design.
3. Pressure Resistance Test
Applies a specified pressure to the liquid-cooled channels of the tested component to test its pressure resistance and sealing performance.
Advantages of Water-Cooled Chillers
The Zhongzhi proportional valve high temperature liquid-cooled testing machine uses a water-cooled design, which offers the following advantages compared to air-cooled models:
1. High-Efficiency Heat Dissipation
Compared to air-cooled chillers, water-cooled units are less affected by ambient temperature, have smaller operating temperature differences, and achieve higher heat exchange efficiency.
2. Superior Energy Efficiency
Water-cooled chillers generally have a higher energy efficiency ratio than air-cooled chillers, achieving lower energy consumption under the same operating conditions. This is because the water-cooling system has a higher heat exchange coefficient, resulting in a lower compressor operating load and avoiding energy waste under high-temperature and high-pressure conditions.
3. Convenient Maintenance
Water-cooled chillers, due to their compact structure and high degree of modularity, offer greater advantages in maintenance.

Frequently Asked Questions
1. When Testing Multiple Channels, Can Each Channel Use Different Flow Rates?
Typically, different flow rates are possible as long as each channel is equipped with an independent proportional valve and flow sensor.
2. How Does the Proportional Valve Achieve Flow Control?
The proportional valve automatically adjusts the valve opening according to the set flow target value to achieve precise flow control and stable output.
3. Does the Water-Cooled Model Require External Cooling Water When Installing It?
need. The equipment needs to be connected to a circulating cooling water system that meets technical requirements to ensure stable operation of the equipment.
4. Can the Number of Output Channels Be Expanded According to Later Needs?
Whether later extensions are supported depends on the design. If there is a need for channel expansion, it is recommended to confirm it during the equipment selection stage to ensure that subsequent use needs are met.
5. Can the Proportional Valve High Temperature Liquid-Cooled Testing Machine Be Customized?
Can. Zhongzhi can customize exclusive solutions according to your working conditions (temperature range, flow rate, environmental conditions, etc.).
