Portable active temperature control apparatus
An active temperature control apparatus 100 comprises an insulating housing 10 provided with a main control unit 12, a vacuum insulation layer 20 and storage container 40 disposed in the insulating housing, a top cover 50, and a heating module 60. The heating module includes a conductive coil 62 which receives a high-frequency AC from the main control unit to continuously generate an alternating magnetic field, and a thermocouple connected to the conductive coil and the main control unit and which is used for feeding back a temperature to the main control unit to adjust an operating voltage to change the high-frequency AC. The alternating magnetic field generated by the conductive coil enables the metal of the vacuum heat insulation layer to generate heat and perform heat exchange with the storage container. The heating module may be provided between an inner insulating housing 30 and the vacuum insulation layer. The coil may be formed as a two-dimensional concentric circle, or as a three-dimensional symmetric shape.
