Abstract
The invention discloses a stainless steel pipe water-cooling resistor which belongs to the field of an electro-arc heater in an aerospace aerodynamic heat arc wind tunnel test. The stainless steel pipe water-cooling resistor comprises a plurality of stainless steel pipes and an outer clamp plate, wherein two ends of each of the plurality of stainless steel pipes are provided with filler necks; cooling water is introduced into an inner cavity of each stainless steel pipe; the outer clamp plate clamps the plurality of stainless steel pipes; wherein part or all the plurality of stainless steel pipes are connected with plates connected with the filler necks in series, or in parallel, or in series and in parallel simultaneously, so as to form a stainless steel pipe water-cooling resistor main body; the stainless steel pipe water-cooling resistor main body is connected with electrodes by terminals, and the terminals are connected with the filler necks. Due to the adoption of the technical scheme, the cooling effect of the stainless steel pipe water-cooling resistor is preferable, the integration mounting is facilitated, the resistance adjustment is simple and clear, and the power is high.
Description
technical field [0001] The invention belongs to the field of an aerospace aerodynamic thermal arc wind tunnel test arc heater, and in particular relates to a stainless steel tube water-cooled resistance. Background technique [0002] The arc heater is one of the main heat source equipment for the ground thermal simulation assessment test of the aerospace vehicle. The long straight tube type DC arc heater in the arc heater, especially the tubular arc heater, its arc operation parameters show a typical "negative resistance" characteristic. In order to make the arc burn stably, a certain resistance value needs to be connected in series in the electrical main circuit of the ballast resistor. [0003] A laminated arc heater in the long straight tube type DC arc heater, also known as a compressed arc arc heater, has the advantages of high enthalpy and stable operation, and is an ideal arc solution for hypersonic and long-endurance aerospace vehicles. Heating equipment which, whe...
