Who We Are
Changzhou Tinghao Electronic CO.,LTD is an industrial manufacturer of oil coolers and heat exchangers. We design, build and test air-cooled and water-cooled oil coolers in our own factory in Jiangsu, China — with 12000 m2 of production space and a dedicated engineering team.
Unlike trading companies, we control the whole process: thermal design, core manufacturing, vacuum brazing, machining, assembly and testing. That means we can guarantee quality, respond fast to custom requests, and offer direct factory pricing.
What We Do
- Custom oil coolers — air-cooled and water-cooled, designed to your parameters.
- OEM / ODM manufacturing — from your drawing or from our design, under your brand.
- Engineering support — sizing, drawing review and thermal recommendations within 24 hours.
- Testing and documentation — pressure and leak testing on every unit, with reports available.
Global Export & Packaging
From our factory in Changzhou, we ship custom radiators and oil coolers worldwide. Every export order is packed in secure wooden crates with protective inserts, container-loaded and documented for customs - so your custom aluminum oil cooler arrives as built, not as damaged. As an OEM oil cooler factory, we handle the whole journey from vacuum brazing to the shipping container.
Our Team
- Engineering team — thermal and mechanical engineers who size coolers and review drawings daily.
- Foreign trade team — multilingual sales engineers who understand export documentation, packaging and shipping.
- Quality team — dedicated inspectors who test every cooler before it leaves the factory.
Our Standards
- ISO 9001 & CE certified quality management
- 100% pressure and leak testing before shipment
- Material and process traceability for every batch
- Continuous improvement based on customer feedback

Customers choose us because we answer the hard questions — what heat load, what pressure drop, what space, what environment — and then deliver a cooler that fits the real application. If you are tired of catalog parts that almost fit, send us your problem.
Facing overheating issues in your hydraulic system? Send us your specs or drawings — our engineers will size the right cooler for you within 24 hours.
