SINRUI developed a customized cooling package for a U.S. heavy-duty drilling equipment OEM using different heat-exchanger structures for different circuits. The hydraulic oil circuit uses a vacuum-brazed aluminum bar-and-plate cooler pressure-tested to 550 PSI, while the main radiator and charge-air cooler use replaceable 99.9% copper tubes with flexible FKM seals. The article explains the engineering logic behind each structure, the advantages of field-replaceable tubes, and SINRUI’s four-step inspection process covering sealing, pressure performance, coating quality and dimensional compatibility before shipment.
SINRUI supplied a batch of customized bar-and-plate cooling products for Atlas Copco / Epiroc mining drill rigs, including hydraulic oil coolers, compressor oil coolers and radiators for part numbers 3222331321, 3222331322 and 3222331379. This article explains why aluminum bar-and-plate construction is well suited to demanding drill-rig applications, focusing on resistance to pressure fluctuations, vibration durability, heat-transfer performance and installation compatibility. It also highlights the project background, customer feedback and key considerations for selecting reliable aftermarket cooling solutions for mining equipment.
