SUNENG supplies custom heat sinks and liquid cold plates for power electronics, energy storage and industrial equipment. Start with a drawing, a reference part or the space and cooling requirements of your equipment.
The manufacturing route, sample scope and acceptance criteria are agreed for your project. CNC machining supports the product; it is not the limit of the service.
For projects considering air cooling, define the installation envelope and the heat source before choosing the component geometry.
For projects using a liquid cooling loop, review the plate together with its interfaces and operating conditions, not as a standalone machined block.
This published product shows one available construction. Plate dimensions, tube route and coolant connections are reviewed against your drawing and application.

Review the material, dimensions, mounting interfaces and proposed manufacturing route before sampling. Confirm the inspection scope and the evidence needed to release the part for production.
A dimensional sample and a validated cooling assembly are not the same approval. Agree which thermal, sealing and installation checks your project requires, and how those checks will be performed.

Short, practical guidance for selection, specification, inspection and production approval.
01
A practical route decision using heat load, airflow, coolant conditions and installation limits.
Read the guide02
The heat-source map, coolant circuit and contact interface details that make a review useful.
Read the guide03
What to control at the contact face before dimensional and thermal approval.
Read the guide04
A practical approval plan for samples, inspection evidence and repeat production.
Read the guideA complete drawing is helpful, but you can start with the information you have. Tell us what is fixed, what can change and which requirements still need review.
Performance, test methods, lead time and production quantity are confirmed against the project requirements, rather than a generic website specification.
