The invention provides a split type intra-vehicle temperature sensing device provided with a non-suction type temperature sensor. The split type intra-vehicle temperature sensing device comprises a surface temperature sensor arranged between air conditioner control panel shell walls on two sides and further comprises the non-suction type temperature sensor arranged on an air conditioner main PCB. Heat transfer between solid is conducted by the non-suction type temperature sensor and the surface temperature sensor. The surface temperature sensor is connected with a heat transfer layer, and the non-suction type temperature sensor is connected with a heat insulation sealant layer arranged on the non-suction type temperature sensor. Heat transfer between solid is conducted by the non-suction type temperature sensor and the surface temperature sensor, a fault tolerance device is arranged in allusion to the sunlight and object touching situation and the damage situation of the surface temperature sensor, a heat transfer theory algorithm is adopted for highly precisely recognizing the temperature in a vehicle, the deviation generated when noise exists or the wind speed is small is reduced, and thus an air conditioner control system conducts control more accurately, and the comfort level of users in the vehicle is ensured.
