Zhejiang Sanhua Intelligent Controls Co., Ltd. — AI supply-chain exposure

Zhejiang Sanhua is a Chinese maker of thermal-management components — valves, pumps and heat exchangers — that grew up supplying the appliance and electric-vehicle industries. It is now carrying that expertise into data-center liquid cooling, where the same class of parts move heat away from densely packed AI servers. As racks grow hotter, air cooling runs out of room, and the plumbing that circulates coolant becomes an enabling part of the build.

The structural hook is that Sanhua already manufactures at scale the precise components liquid cooling needs, honed in the demanding EV thermal business. That gives it a credible path into a fast-growing part of the AI stack without starting from scratch. But it sits well downstream of the silicon, one supplier among several in a competitive components market. The model places it at the periphery, exposed to the shift toward liquid cooling rather than commanding pricing power over it.
