Heat-storage heating body and preparation method thereof

Abstract

The invention provides a heat-storage heating body and a preparation method thereof. The heat-storage heating body comprises a heat storage brick and a heating plate; a cavity is formed in the middleof the heat storage brick; and the heating plate arranged in the cavity is in contact with the heat storage brick. And the heat storage brick is formed by integrated sintering. The eat-storage heatingbody consists of the heat storage brick and the heating plate. Because the heat storage brick is formed by integrated sintering and has an integrated structure and thus no many connection mechanismsare needed, so that the structure of the heating body is simplified and thus the heat storage brick that is formed by integrated sintering and has an integrated structure is convenient to operate. Furthermore, the cavity is formed in the heat storage brick, the heating plate is arranged in the cavity, and the heat storage brick and the heating plate are in close contact, so that the high utilization rate of the heat is ensured and thus the work efficiency of the heat-storage heating body is improved. Under the circumstance of equal heat storage heating, the temperature of the heating plate does not need to be too high, so that the service life of the heating plate is prolonged.

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
