Double-layer type resistor air-out tube head

Abstract

The invention relates to a double-layer type resistor air-out tube head, which is provided at one side of a resistor casing and is composed of an external layer component, an internal layer component, a support bar and an interlayer support member. The internal layer component is provided in the external layer component, a gap is provided between the external layer component and the internal layer component, the support bar is connected to the inside wall of the external layer component, and the interlayer support member is provided between the external layer component and the internal layer component. Compared with the prior art, the air-out tube head uses air between the two layers of the air-out tube head for heat insulation, thereby the temperature on the external layer surface can be reduced, hot-air discharged from the resistor is directly contacted and performed heat transfer with the internal layer of the air-out tube head, air is existed between the internal layer and the external layer, air is a poor conductor of heat, heat can be effectively prevented to be transferred to the external layer component, the whole air-out tube head not welding but bolt or riveting, thereby the effect of environmental protection and low carbon can be achieved.

Description

technical field [0001] The invention relates to an air outlet pipe head, in particular to a double-layer resistor air outlet pipe head. Background technique [0002] Resistors need to dissipate heat when they work, so some resistors are designed with an outlet pipe that can exhaust hot air. At present, the outlet pipe head of the resistor mostly adopts a single-layer welded structure, that is, only the air outlet pipe head uses only one layer of metal, and the parts are assembled by welding. In this way, the hot air directly contacts the head of the air outlet pipe for heat transfer, resulting in a higher surface temperature of the head of the air outlet pipe, which may cause adverse effects on people or other equipment around the resistor in some occasions. Moreover, the welding work takes a long time, which is not good for the operator's health, and the surface treatment after welding also has a certain impact on the environment. The working components will also be deform...

Problems solved by technology

In this way, the hot air directly contacts the air outlet pipe head to transfer heat, resulting in a higher surface temperature of the air outlet pipe head, which will cause adverse effects on people or other equipment around the resistor in some occasions.

Moreover, the welding work takes a long time, which is not good for the operator's body, and the surface treatment after welding also has a certain impact on the environment. The working components will also be deformed to varying degrees after welding, which may affect the overall accuracy and appearance.
