The invention discloses a temperature control platform for sectionally controlling a temperature of a micro-fluidic chip. The temperature control platform comprises a temperature control platform body, an intelligent temperature regulator and a constant-temperature circulator, wherein the temperature control platform body consists of a housing, a cool plate, a hot plate, a semiconductor refrigerating sheet with a cool surface facing upwards, a heater, a heat radiator and a metal conduit from the external to the internal, and the cool plate and the hot plate are provided with a temperature measurer. By utilizing the high-performance micro semiconductor refrigerating sheet and the ceramic heating sheet, the size of the sectional-type micro-fluidic chip temperature control apparatus is greatly reduced, and for the characteristic of the small area of the micro-fluidic chip, the practicability of the temperature control platform is improved; by adopting the commercial temperature controller Tempco TEC-220, according to the temperature data of the hot plate and the cool plate collected by a platinum electrode, the high precision automatic temperature control is realized by precisely controlling the operation and stopping of the semiconductor refrigerating sheet and the ceramic heating sheet; and by adopting the HX-1050 constant-temperature circulator, the temperature of the circulating liquid is kept at 60 DEG C below zero to 50 DEG C, the heat radiation requirement of the apparatus can be met, the experiment energy consumption can be reduced, the application cost is decreased, and the temperature control platform is suitable for realizing experiments such as biological PCR, liquid drop and capsule solidification and melting, crystal phase changing, material synthesis by controlling temperature in the micro-fluidic chip.
