The invention belongs to a micro-channel device, and particularly relates to a micro-channel radiator integrated with a temperature sensor. The micro-channel radiator includes a micro-channel box, a bonding layer, a micro-channel cover, a coolant inlet, a coolant outlet, a micro-channel groove, and a temperature sensor. The temperature sensor is integrated inside the micro-channel radiator. The temperature sensor can be arranged flexibly. Multi-point and high-spatial-resolution real-time monitoring is realized. The reliability of the micro-channel radiator can be improved, and the radiator canbe optimized. Compared with an external temperature sensor, the temperature obtained is less influenced by environment, the result can reflect the status inside a flow channel more accurately, and the overall reliability of the micro-channel radiator is improved. The coolant and the temperature sensor directly contacting each other are separated by the bonding layer, so that the temperature sensor will not be affected by direct contact with the coolant, and the stability and accuracy of the temperature sensor will not be reduced and even the temperature sensor will not be short-circuited.
