The invention discloses a method and device for maintaining constant temperature. The device for maintaining the constant temperature comprises an insulation barrel, a heat collection structure, a first electronic control valve, a temperature sensor and a controller. The insulation barrel is used for storing dry ice; the heat collection structure communicates with the insulation barrel through anair pipeline; the first electronic control valve is arranged on the air pipeline between the insulation barrel and the heat collection structure and is used for opening and closing the air pipeline; the temperature sensor is arranged outside the insulation barrel and used for detecting the external environment temperature of the insulation barrel; the controller is electrically connected with thefirst electronic control valve and the temperature sensor, when the external environment temperature detected by the temperature sensor exceeds a preset temperature range, the first electronic controlvalve is controlled by the controller to open. The method and device for maintaining the constant temperature is less in method steps, convenient to operate, simple in device structure and low in production cost, and can make full use of the dry ice and keep the external environment at the constant temperature for a long time.
