Established in the early 1980s, Dgnks Electrical Appliance Co., Ltd. is China vortex cooler manufacturer and designer of small electrical appliance and household appliance in China, with 30 years development experience. We have received CE, GS, EMC, ETL, SAA, IRAM, SASO, PAI, KTL, JET and ISO9002 quality standard certification. Moreover, we utilize advanced production equipment such as plastic injection machines and 6 washing (Spin Dry) machine assembly and test lines. Furthermore, we possess 12 mold-making machines and 15 sets of diverse testing instruments. Accordingly, our customized vortex coolers sell well both home and abroad. |

The cooled air produced by the tube inside the enclosure cooler is discharged into the enclosure while hot air in the enclosure is vented outside the box into the surrounding area through a built-in relief valve. The built-in relief valve and the cooler-to-enclosure seal maintain the integrity of NEMA or JIC boxes. Air introduced into the enclosure is filtered before it enters the vortex cooler, creating a clean, cool and controlled environment inside the enclosure and helping to keep controlled processes up and running. An added benefit is that the enclosure cooler produces a slight positive pressure inside the cabinet to keep out dust and dirt. Vortex Coolers use an internal vortex tube to convert factory compressed air into a low pressure, cold air stream that is distributed throughout the cabinet. The chilled air stream creates a slight positive pressure inside the enclosure to prevent dirt or dust from entering - even in the most challenging environments. From small computer cabinets and touch screen control panels to large electrical panel boxes, Vortex Coolers offer efficient and reliable enclosure protection from heat and dirt related shutdowns. |

Power densities have increased as cabinet areas have gotten smaller. Packing components more densely reduces circuit size and increases speed but leaves little room for heat dissipation. Because industrial plants have become more dependent on sophisticated microprocessors, programmable logic controllers (PLCs) and adjustable speed drives, the need for proper heat dissipation has assumed critical proportions. Tightly packed cabinets restrict airflow, resulting in rapidly rising internal temperatures and increasing control failures.Thermal testing has proven that natural convection cooling is not adequate for today's smaller, high power density enclosures. Heat dissipation by forced convection (fan cooling) is the most frequently used method of cooling. Forced-air cooling systems can provide heat transfer rates that are 10 times greater than those achievable with natural convection and radiation, but even this is not adequate to cool faster electronic components when they are located in hostile plant environments. |
