A low flow resistance self-insulating air pipeline heating device

Abstract

The invention belongs to pipeline heating technology, in particular to a low flow resistance self-insulating air pipeline heating device. The low flow resistance self-insulating air pipeline heating device of the present invention comprises an air inlet rolling wave joint assembly, a cylinder wall assembly, an electrical connection socket, and an air outlet rolling wave joint assembly. Wherein, the roll wave joint assembly at the air inlet and the roll wave joint assembly at the air outlet are sleeved on both ends of the cylinder wall assembly, the electrical connection socket is arranged on the cylinder arm assembly, and a drag reducing heating wire bracket is arranged inside the cylinder arm assembly An assembly and an armored heating wire, the armored heating wire is arranged around the drag-reducing heating wire support assembly. The low flow resistance self-insulating air pipeline heating device of the present invention can effectively reduce the flow loss through the structural design of the heating bracket assembly and the optimization of the wiring of the armored heating wire, so that the product has insulation performance, improves heat dissipation performance, and has high temperature The automatic power-off function prevents the temperature from being too high, effectively guarantees product safety, and has great practical application value.

Description

technical field [0001] The invention belongs to pipeline heating technology, in particular to a low flow resistance self-insulating air pipeline heating device. Background technique [0002] With the continuous advancement of aviation manufacturing technology, the single flight time of aircraft is getting longer and longer, and the mission of contemporary aircraft to perform long-duration and trans-oceanic flights is becoming more and more normal. Therefore, during long-distance flights, the need to create a comfortable environment for the crew in the aircraft cabin has become increasingly prominent, so it is often necessary to provide on-board heating equipment to heat the cabin environment. [0003] However, the existing air heating devices mostly use bare wires for heating, have no insulation performance, low safety, and no drag reduction design, and aircraft equipment has high requirements for energy consumption and safety, so it is urgent to develop a Products with low...
