一种电加热器
摘要：
本发明涉及一种电加热器，其特征在于：它包括底端密封的陶瓷套管，设置在所述陶瓷套管内的陶瓷芯，缠绕在所述陶瓷芯外壁的电阻丝，以及设置在所述陶瓷芯与所述陶瓷套管之间的导热绝缘粉末。本发明由于在陶瓷芯的外壁缠绕电阻丝，在陶瓷芯与陶瓷套管之间填充导热绝缘粉末，因此既可以有效地传热，又可以有效地保护电阻丝在高温下不被酸、碱、盐类、金属及金属合金等蓄热材料腐蚀或侵蚀，极大地延长了电加热器的使用寿命，同时由于有陶瓷套管的保护，使用时可以将电加热器直接埋入被加热介质中，实现内部加热，减小加热过程中热量的散失，提高加热效率和电能的利用率。本发明作为一种新型的加热器，可以广泛用于各种蓄热用电装置中。
摘要（英）：

This invention relates to an electric heater including a ceramic sleeving with sealed bottom, a ceramic core set in it, resistance wires winding outer wall of the said core and heat-conducting insulation powders between the core and said ceramic sleeving. Since resistance wires wind the outer wall of the core and powder of heat-conduction and insulation is filled between the sleevings, it can either transfer heat effectively or provent the resistance wire from corrosion or intrusion by acid, alkali, salt and alloys so as to prolong the life of electric-heaters, at the same time, since it is protected by ceramic sleeving, the heater can be inlet in the heated medium to realize internal heating and reduce dispersion of heat to increase efficiency and usability of electric energy.
