30W Ceramic Case

30W ceramic case is a high-performance thermal management enclosure specifically designed for high-power electronic devices with extreme heat dissipation needs-including new energy vehicle on-board chargers (OBC) and DC-DC converters-relying on silicon carbide (SiC) ceramic as its base material, a choice dictated by the material's exceptional thermal and structural properties. According to its core specifications, this features a thermal conductivity of up to 120 W/m·K, which is far higher than that of ordinary alumina ceramics, and boasts excellent thermal shock resistance, capable of withstanding temperature differences exceeding 1000℃ without cracking-critical for devices operating in fluctuating high-temperature environments.

The manufacturing process of 30W ceramic case is optimized to maximize the performance of SiC ceramic: after precision shaping of high-purity SiC powder, it undergoes high-temperature sintering (consistent with the 1400-1800℃ range for advanced ceramic processing) to ensure structural densification, followed by surface treatment to enhance compatibility with power device mounting. In practical applications, 30W ceramic case is a core component in new energy vehicle powertrains: when installed in the engine bay (where ambient temperatures can reach 150℃), it effectively controls the temperature difference between the core of key power devices (such as MOSFETs and IGBTs) and the outer shell to within 10℃. This precise thermal control not only prevents device performance degradation due to overheating but also improves electrical energy conversion efficiency by approximately 5%-a key contributor to extending the vehicle's driving range.
