With the rapid growth of demand for computing power driven by artificial intelligence, high-performance computing (HPC), and data centers, liquid cooling is rapidly replacing traditional air cooling and becoming a mainstream thermal management solution for high-heat-density applications.

Industry experience and engineering practice have repeatedly demonstrated that the surface quality of internal flow channels in liquid cooling systems has a direct impact on cooling efficiency and plays a critical role in the long-term reliability and service life of the entire system.

For liquid cooling system integrators pursuing maximum thermal performance, surface defects inside cast components can cause much more than increased flow resistance and higher pump power consumption. They may also create potential micro-leakage risks, which can ultimately compromise the stability and safety of data center operations.

Dalian Huixiang Precision has officially entered the liquid cooling industry. Building on years of experience in advanced investment casting, the company has developed integrated manufacturing solutions featuring high surface finish for critical liquid cooling components, including cold plates, manifolds, and pump housings.

By leveraging precision casting technology, Huixiang Precision aims to address leakage risks associated with conventional welded structures at the source.

Key Advantages

Controlled and Consistent Surface Roughness

The surface roughness of internal flow channels can be consistently controlled at Ra ≤ 3.2 μm, meeting the stringent requirements of most liquid cooling applications for flow resistance and hydraulic performance. This helps reduce flow losses and improve overall heat transfer efficiency.

Complex Flow Channels in a Single Casting

Using the lost-wax investment casting process, Huixiang Precision can produce complex internal passages with multiple channels, variable cross-sections, and irregular geometries as an integrated near-net-shape casting.

This eliminates the need for multiple welded sections and helps remove potential leakage points associated with weld seams at the design and manufacturing stage, significantly improving sealing reliability and pressure resistance.

Wide Range of Material Options

Huixiang Precision offers multiple material options, including 304 stainless steel, 316L stainless steel, and duplex stainless steel.

These materials provide excellent corrosion resistance and are suitable for long-term operation with different cooling media, including water-glycol mixtures and deionized water, under high-temperature and high-pressure conditions.
