Abstract

The invention discloses an infrared radiation ceramic heater, which comprises a quartz outer tube and a quartz inner tube, wherein two ends of the quartz outer tube and two ends of the quartz inner tube are connected in a melted and closed mode respectively; a cavity is arranged between the inner wall of the quartz outer tube and the outer wall of the quartz inner tube and provided with a silicon carbon rod inside; the diameter of a through hole in the middle of the quartz inner tube is more than or equal to the length of the quartz outer tube; electrodes are arranged at the ends of the silicon carbon rod; and a silicon dioxide pad is arranged on the outer wall or the inner wall of the ends of the silicon carbon rod. The infrared radiation ceramic heater is mainly used for medium heating of heaters, can also be used for heating in industrial production, and is particularly applicable to heaters adopting water circulation. The product can directly heat water to make the water temperature rise rapidly, water absorbs heat through the quartz outer tube and the quartz inner tube, the heat efficiency is high, because the infrared radiation rate is larger than 97 percent, the energy consumption is low, and compared with the prior silicon fiber wire heating and electrothermal tube heating, the heating mode saves energy by 38 to 45 percent. The infrared radiation ceramic heater has the advantages of long service life along with thoroughly overcoming the defect of easy failures of electric heating and carbon fiber heating.

Description

technical field [0001] The invention relates to a heater, which is an infrared radiation ceramic heater. Background technique [0002] There are generally two forms of heating in winter: one is centralized heating based on coal or oil; the other is electric heating. The advantages of electric heating are mainly reflected in no pollution, easy to use, easy to control, and energy saving. However, the shortcomings of electric heating are still prominent: slow heating, high power consumption, short service life of electric heaters, and large maintenance. For this reason, the field provides many structures for heaters, such as heaters controlled by carbon fibers, ceramic integral heaters, and infrared electric heaters. However, due to the existence of many defects in these structures, no products have been formed so far. Therefore, how to design a heater that heats up quickly, consumes less power, and can drive water circulation is one of the main research topics in this field...
