Frequently Asked Questions
What is the market size of China's heat exchanger industry?
China's heat exchanger market reached approximately CNY 150 billion in 2024. Shell-and-tube exchangers dominate in heavy industry, while plate heat exchangers are the fastest-growing segment driven by HVAC and data center cooling demand.
Which heat exchanger types are most demanded for data centers?
Brazed plate heat exchangers (BPHE) and microchannel heat exchangers are preferred for data center liquid cooling. SWEP China and Shuangliang supply compact BPHEs for rear-door and immersion cooling configurations in hyperscale data centers.
How do Chinese heat exchanger manufacturers serve the EV sector?
Chinese manufacturers like Dunham-Bush and Shuangliang produce plate-fin and microchannel evaporators and condensers for EV battery thermal management systems. These components are specified in BYD, XPeng, and NIO thermal management modules.
What quality standards do Chinese heat exchanger companies follow?
Leading manufacturers hold ASME Section VIII pressure vessel certification, PED (CE), and GB/T 150 Chinese pressure vessel standards. Lanshen and Huaneng Power Equipment maintain ASME U-stamp certification for their shell-and-tube products.
How is China's heat exchanger industry evolving toward sustainability?
Manufacturers are developing high-efficiency heat exchangers with enhanced surface geometries to reduce energy consumption by 15-30%. Shuangliang's absorption chillers use waste heat instead of electricity, while plate heat exchanger makers optimize channel designs for lower pressure drop and higher heat transfer coefficients.
