The utility model discloses a self-adaptive control type anti-condensation device, which comprises a shell, an electronic condensing assembly, a central control unit, a condensing-end temperature sensor, a heat dissipation-end temperature sensor and an ambient temperature and humidity sensor. The electronic condensing assembly, the central control unit, the condensing-end temperature sensor, the heat dissipation-end temperature sensor and the ambient temperature and humidity sensor are arranged in the shell. The device is characterized in that the electronic condensing assembly is composed of an electronic cooling element, a condensing end, a heat dissipation end and a heat dissipation fan. The electronic cooling element is provided with a cooling surface and a heating surface. The cooling surface clings to the condensing end, and the heating surface clings to the heat dissipation end. The heat dissipation fan is mounted in front of the heat dissipation end. The condensing end is provided with the condensing-end temperature sensor. The heat dissipation end is provided with the heat dissipation-end temperature sensor. The ambient temperature and humidity sensor is arranged inside the shell. The device is reasonable in both layout and structure. By means of the device, the temperature of the condensing end, the temperature of the heat dissipation end, the ambient temperature and the ambient humidity can be effectively monitored and adjusted. Therefore, the problems in the low-temperature and high-humidity condition that an air channel is easily blocked and the dehumidifying effect is poor can be avoided.
