AI Technical Summary
Existing heat transfer oil samplers have long cooling times and cannot achieve rapid cooling of high-temperature heat transfer oil.
Employing the principle of rapid cooling using vortex tubes, the system connects to a cold air duct via the vortex tubes. The vortex tubes divide the compressed gas into two streams of air, one hot and one cold. The cold air enters the cold air duct through the cold air outlet of the vortex tubes, and the fins enhance the heat exchange effect, thus achieving rapid cooling of the high-temperature heat transfer oil.
It achieves rapid cooling of heat transfer oil, reducing cooling time by more than 50% compared to traditional forced cooling samplers using fans and coils, and by more than 90% compared to natural cooling samplers. In addition, the equipment is lightweight, compact, and has low maintenance costs.
