Abstract

The invention discloses a temperature control unit based on shape memory alloy. One end of the temperature limiter shape memory alloy of a temperature control switch of the temperature control unit is bonded to a heat conduction top cover, and the other end of the temperature limiter shape memory alloy is connected with an insulating sheet. A first conducting strip is bonded below the insulating sheet, and a base of the temperature control switch is formed by integrally connecting a cylindrical hollow structure and a bottom disc. The insulating sheet, the first conducting strip and the temperature limiter shape memory alloy are arranged in the cylindrical hollow structure. The cylindrical surface of the base is provided with an opening, and a conducting strip of the temperature control switch is embedded into the opening. The base of the temperature control switch is an insulator, the bottom of the first conducting strip in a temperature limiter is provided with a round piece, the bottom of the first conducting strip is connected with a lever, and the lever is connected with a button of a temperature control unit application device. The temperature limiter shape memory alloy is one-way shape memory alloy. By means of the shape memory alloy, the temperature control unit has the advantages of being high in stability, simple, safe, high in control precision, high in response speed and the like.

Description

technical field [0001] The invention relates to a temperature control circuit switch, in particular to a temperature control unit based on a shape memory alloy, which is a temperature control switch. Background technique [0002] At present, there are three main types of temperature control switches: pressure type temperature control, bimetal temperature control and thermal ferrite temperature control. Among them, the pressure type temperature control mainly realizes temperature control by converting the change of the controlled temperature into the change of the pressure or volume of the closed space; the bimetallic temperature control is made according to the principle of thermal expansion and contraction of objects; The temperature control is achieved by using the magnetic properties of the thermosensitive ferrite as it changes with temperature. However, almost all of these temperature control systems have shortcomings such as slow action response time, easy to be affect...
