The invention discloses a combined-type infrared thermal imager. A digital infrared machine core assembly and a digital camera of the infrared thermal imager are both connected with a first wireless communication module through an I/O bus. A first data communication end of a data processor is connected with a data communication end of a microprocessor. A second data communication end of the data processor is connected with a man-machine interaction module. A wireless communication interface of the microprocessor is connected with a second wireless communication module. A data storage interface of the microprocessor is connected with a storage. The first wireless communication module and the second wireless communication module are connected through wireless communication. The combined-type infrared thermal imager facilitates detection of areas which are hard to reach for operation personnel and the detection result is more accurate.
