Description
Technical Field
[0001] This utility model relates to the field of bimetallic strip technology, and in particular to a high-efficiency heat dissipation resistive bimetallic strip. Background Technology
[0002] Bimetallic sheets are composite materials composed of two or more metals or other materials with suitable properties. Bimetallic sheets are also called thermal bimetallic sheets. Due to the different thermal expansion coefficients of the component layers, when the temperature changes, the deformation of the active layer is greater than that of the passive layer. As a result, the entire bimetallic sheet will bend towards the passive layer side, and the curvature of this composite material will change, thus producing deformation.
[0003] Existing bimetallic resistors generate a lot of heat during operation. If the heat sink cannot dissipate heat in time, the bimetallic resistor will deform too much and become unusable. Utility Model Content
