Problems solved by technology

The power requirement of the electric heater is large, and the installation space requirement of the internal electric heating element is correspondingly increased; under the dual working conditions of high working pressure and temperature, the strength requirement for the container of the electric heater is extremely high, which makes the existing technology The method of increasing the volume by increasing the diameter of the container often cannot meet the requirements of use, because under the requirement of strength, the increase of the diameter of the container will inevitably put forward higher requirements for the thickness of the container; on the other hand, the existing electric heater is usually cooled by water Due to the low boiling point of water, the temperature difference between it and the circulating medium is very large, resulting in large heat loss and large thermal stress of the electric heater, which seriously affects its long-term use.

Abstract

The invention relates to a high-power high-voltage electric heater. The electric heater comprises a shell which is through in the front-back direction, the outer wall face of the shell is sleeved with an outer shell at intervals to form a closed space, and an oil inlet and an oil outlet are formed in the two ends of the outer shell respectively; a pipe body is fixedly sleeved with the shell in the length direction, and multiple sets of heating assemblies are installed in the pipe body in the length direction at intervals; a plurality of electrode assemblies of the same group of power supplies are arranged on the wall surface of the shell in front of the shell at intervals along the circumferential direction; the plurality of groups of heating assemblies are electrically connected with the group of power supplies; and a rectification assembly is installed at an inlet in the shell. According to the electric heater, the multiple heating assemblies are arranged at intervals in the length direction, the power of the electric heater is effectively improved, and meanwhile the overall diameter size of the electric heater is greatly reduced; multiple groups of heating assemblies adopt the same group of power supply, and the leakage risk is effectively reduced by reducing the number of the electrode introducing devices; and an outer wall surface oil cooling mode is also adopted, so that the electric heater is small in overall heat loss, small in thermal stress and good in practicability.

Description

technical field [0001] The invention relates to the technical field of electric heaters, in particular to a high-power high-voltage electric heater. Background technique [0002] The electric heater is one of the important equipments for the performance testing of aviation aircraft and its components. According to the test requirements, it requires high working pressure and high heating power. The power requirement of the electric heater is large, and the installation space requirement of the internal electric heating element is correspondingly increased; under the dual working conditions of high working pressure and temperature, the strength requirement for the container of the electric heater is extremely high, which makes the existing technology The method of increasing the volume by increasing the diameter of the container often cannot meet the requirements of use, because under the requirement of strength, the increase of the diameter of the container will inevitably pu...
