Temperature control device for biological microscope imaging system

The invention relates to a control device applied to the field of life science research and used for controlling the temperature of a sample in a biological microscope imaging system. The device comprises a temperature sensor, a refrigerator, a heater, a power module, a control module, and a sample fixing module. The refrigerator and the heater are fixed to the sample fixing module. The temperature sensor is put in the sample fixing module, and used for measuring the temperature of a sample in the module. The control module automatically controls the refrigerator or the heater to work according to temperature information detected by the temperature sensor. If the temperature of the sample in the sample fixing module is too high, the control temperature controls the refrigerator to work to reduce the temperature of the sample in the sample fixing module. If the temperature of the sample in the sample fixing module is too low, the control temperature controls the heater to work to increase the temperature of the sample so as to control the sample temperature in the sample fixing module to fluctuate within a small range of preset value. The control device of the invention can exchange data with a computer through a communication interface of the control module, and the temperature is read, displayed and set through the computer.
