Abstract

The invention discloses a shape memory alloy temperature control current switch, comprising a left rack, a right rack, a guide rod, a slide bar assembly and a porcelain cylinder. The guide rod and the slide bar assembly are located on upper parts of the left rack and the right rack; the porcelain cylinder is located on lower parts of the left rack and the right rack; one side of the guide rod is provided with a brush slid wire; the slide bar assembly comprises a slide bar, a pyriform connecting block, a slide plate and a brush wafer; a biasing spring is arranged between the pyriform connecting block and the left rack; a shape memory alloy spring is arranged between the pyriform connecting block and the right rack; two ends of the porcelain cylinder are respectively fixed to the lower parts of the left rack and the right rack through screws; the porcelain cylinder is wound with a resistance wire. The shape memory alloy temperature control current switch has the characteristics of fast response speed and wide change scope, and can realize a plurality of work conditions.

Description

technical field [0001] The invention relates to the technical field of temperature controllers, in particular to a shape memory alloy temperature-controlled current switch. Background technique [0002] Shape memory alloy is a material with shape memory effect and superelastic properties. The shape memory alloy undergoes a certain degree of plastic deformation in the low temperature martensite phase, and under the action of temperature, it will undergo inverse deformation to restore the material to its original shape. During the inverse deformation process of restoring the shape, if the shape memory alloy is constrained, it will It will generate a large restoring force, and the restoring force can be used to do work externally, and can be made into various drives. [0003] Based on the temperature sensing and driving characteristics of shape memory alloys, it has broad application prospects in the field of mechanical control. For example, the "steam temperature-sensitive...
