The utility model discloses a high and low temperature therapeutic apparatus and a therapeutic apparatus host thereof, and relates to the technical field of
medical equipment, the high and low temperature therapeutic apparatus comprises a holding bin, one end of the holding bin is fixedly provided with a
temperature control bin, and the
temperature control bin is internally and fixedly provided with a
semiconductor chilling plate; the refrigerating face and the heating face of the
semiconductor refrigerating piece are fixedly connected with heat conduction
copper plates correspondingly, a
water cooling bin is arranged on one side of one heat conduction
copper plate, and the input end of a flow speed acceleration
assembly arranged in the
water cooling bin is in transmission connection with a driving
assembly. According to the utility model, heat generated by the heating surface of the
semiconductor chilling plate is absorbed through the
water cooling bin, and water with temperature rising caused by heat absorption is guided into the cold radiator for cooling treatment, so that the
working temperature of the high and low temperature therapeutic apparatus can be stabilized in a temperature interval required by normal work when the high and low temperature therapeutic apparatus works for a long time, and the
therapeutic effect is good. The operation stability and the service life of the equipment are improved.
