The invention provides a negative thermal expansion type thermoelectric switch. The negative thermal expansion type thermoelectric switch comprises a fixed element, a movable element, a thermal load and a negative thermal expansion element. A first end of the negative thermal expansion element is connected with the fixed element, and a second end is connected with the movable element. The movable element and the negative thermal expansion element are both located between the thermal load and the fixed element, a first end of the movable element makes contact with the fixed element, and a second end of the movable element makes contact with the thermal load when the temperature of the negative thermal expansion element is lower than a preset value. According to the negative thermal expansion type thermoelectric switch provided by the invention, the negative thermal expansion element is adopted as a connecting piece and is connected with the thermal load and the fixed element, the distance between the thermal load and the movable element is changed by utilizing the characteristics that the negative thermal expansion element expands at a low temperature and contracts at a high temperature, the starting and ending of the heating process can be automatically controlled according to the temperature, no extra starting / closing button is needed, conduction and disconnection of a current path are realized, the heating temperature can be sensed at any time, and the safety of an electric heat storage device controlled by the switch is effectively improved.
Description
technical field [0001] The invention relates to the technical field of heat flow path control, in particular to a negative thermal expansion thermoelectric switch. Background technique [0002] The current energy structure is still dominated by traditional fossil energy, but the relationship between the high-grade electric energy generated by the combustion of fossil energy and the supply and demand of users is unstable in time or space. [0003] Therefore, energy storage technology has become an important means to solve the discontinuous energy consumption at the user end and maintain the balance between supply and demand. The heat storage technology is mainly used in power system peak regulation, solar power generation, heating and other fields. One of the commonly used heat storage technologies is to use electric heating to heat up the heat storage material, store heat, and release and use the heat when a specific user needs heat at a specific time. Among them, the resi...
