Heat storage heating element and preparation method thereof

Abstract

The invention provides a heat storage heating body and a preparation method thereof. The heat storage heating body includes: a heat storage brick, a cavity is arranged in the middle of the heat storage brick; a heating plate is arranged in the cavity, and the heating plate and the heat storage brick The heat storage bricks are integrally sintered. The heat storage heating element provided by the present invention includes: heat storage bricks and heating plates. The heat storage bricks are integrally sintered and have an integrated structure without too many connecting mechanisms. The structure is simple and easy to operate; further, the heat storage bricks There is a cavity inside, and the heating plate is placed in the cavity, the heating plate and the heat storage brick are closely bonded, the contact area is increased, the utilization rate of heat is ensured, and the working efficiency of the heat storage heating element is improved. In the case of heat generation, the temperature of the heating plate does not need to be too high, which is beneficial to prolong its service life.

Description

technical field [0001] The invention relates to the field of environmental electrical appliances, in particular to a heat storage heating element and a preparation method thereof. Background technique [0002] At present, the heat storage materials commonly used for heaters on the market include cast iron, ceramics, and magnesia-iron bricks. Among them, magnesia-iron bricks have the characteristics of high heat storage per unit volume and low thermal conductivity, and are the heat storage materials used by most heat storage heaters. . [0003] In the related technology, a groove is provided in the middle of one side of the magnesia-iron brick for placing the heating pipe; The magnesia-iron brick is heated by electricity to store heat, but the gap between the above-mentioned heating tube and the heat storage brick is large, the contact area is small, the thermal resistance is large, and the thermal conductivity of the magnesia-iron brick is low, so the heating of the magnesi...

Problems solved by technology

[0003] In the related technology, a groove is provided in the middle of one side of the magnesia-iron brick for placing the heating pipe; The magnesia-iron brick is heated by electricity to store heat, but the gap between the above-mentioned heating tube and the heat storage brick is large, the contact area is small, the thermal resistance is large, and the thermal conductivity of the magnesia-iron brick is low, so the heating of the magnesia-iron brick occurs. Slow speed, high temperature of the heating tube and reduced service life, and, in order to fix the magnesia-iron brick, keep the heating tube in contact with the magnesia-iron brick, and reduce misalignment, a fixed structure is required to fix and package two or more magnesia-iron bricks , the overall structure is more complex
