Abstract

The invention discloses a compact type organic working medium high-temperature and high-voltage electric heater. The compact type organic working medium high-temperature and high-voltage electric heater comprises a heating pipe which is arranged in an outer pipe at a heating section; flange connectors are symmetrically arranged at two ends of the outer pipe at the heating section; bases are correspondingly arranged at the left side and the right side of the outer pipe at the heating section; a binding post which is inserted into the outer pipe at the heating section and is connected with the heating pipe is arranged in the base; the upper end of the binding post is connected with an external power supply; a mica post, a cylindrical section, another micro post, a sealing ring and a hollow nut are sequentially arranged in the base from bottom to top; insulating sleeves are arranged at the outer side of the cylindrical section and the inner side of the hollow nut. The compact type organic working medium high-temperature and high-voltage electric heater has the advantages of being practical, efficient, simple to operate, cost saving, safe, reliable, and resistant to high temperature and high voltage.

Description

technical field [0001] The invention relates to a working fluid heater, more specifically, to a compact high-temperature and high-pressure electric heater for organic working fluid. Background technique [0002] Organic working fluid heaters can be divided into two types: external heating and internal heating. The internal heating equipment mainly includes circulation heaters, and the external heating methods mainly include heating furnace, electromagnetic heating, heat transfer oil heating, etc. The circulating heater adopts a metal shell to surround the heating element and the heated fluid. It has a large power, a maximum pressure resistance of 20Mpa, and a maximum temperature resistance of 600°C. The heat conduction oil is mostly heated by convective heat exchange outside the pipe, and the heating furnace heats the fluid in the pipe through heat radiation. [0003] When using a circulation heater, to achieve a higher working pressure, the heater shell, seals, and connec...
