Abstract

The invention provides an electric heating tube water-cooled resistor and it preparation process. The electric heating tube water-cooled resistor is characterized by including an aluminum shell. The aluminum shell is internally provided with an electric heating tube, and is provided with a top cover at the upper side. The left side of the aluminum shell is connected to a pagoda joint, and the right side is provided with a cover plate. The right side of the electric heating tube is in connection with a wiring copper bar. For the electric heating tube water-cooled resistor provided in the invention, the electric heating tube is directly immersed in water, the contact is good, the heat transfer speed is fast, the power is high, and the volume is small.

Description

technical field [0001] The invention relates to a novel electric heating tube water-cooling resistor and a preparation process thereof, in particular to a small-volume, high-power resistor, belonging to the technical field of power electronics. Background technique [0002] At present, there are various forms of water-cooling resistors, some of which are too complex in structure, and some of which are too simple. Directly insulate the water pipe and wind it with resistance wire. This method has relatively low insulation performance and unreliable performance. Water cooling methods include: water and electricity separation, water and electricity not separated. The cooling effect of water and electricity separation is slightly worse, but the requirements for water cooling system are not high, and the application scope is wider; the cooling effect of water and electricity without separation is good, but the requirements for water cooling system are high, and there are few appli...
