Description

Cold and hot auto-change over device and cooling appearance Technical Field The application relates to the technical field of medical treatment, in particular to a cold-hot switching device and a cooling instrument. Background A thermoelectric semiconductor refrigerating sheet (refrigerating sheet for short) is an electronic component that realizes a heat pump function by using the peltier effect. The semiconductor particles are clamped by the ceramic substrates on two sides, when direct current is applied, one side absorbs heat to form a refrigeration surface, the other side dissipates heat to form a heating surface, and heat transfer is realized through metal conductor connection. Based on the characteristics, the refrigerating sheet is widely applied to cold and hot treatment equipment, and the functions of the refrigerating surface and the heating surface can be interchanged by switching the directions of electrodes. However, in practical applications, the cooling sheet has inherent drawbacks in electrode switching. Because the temperature difference between the two sides of the refrigerating sheet is large (up to tens of DEG C) when the refrigerating sheet works, the temperature field cannot be reconstructed instantaneously due to thermal inertia. When the electrode polarity is switched, the original refrigerating surface needs to be converted into a heating surface, and the original heating surface needs to be converted into the refrigerating surface, but the inherent temperature difference of the two surfaces can delay the temperature reversal process. If the switching is forced when the temperature difference is large, not only the switching response is slow, but also the service life of the element can be influenced by thermal stress.
