Abstract: A heat exchanger of a desiccant wheel dehumidifier, disclosed in the disclosure, includes a frame and multiple heat exchange platy tubes. The frame has an air inlet and an air outlet. The multiple heat exchange platy tubes are fixed on the frame and are substantially arranged side by side with each other. Every two of the multiple heat exchange platy tubes adjacent to each other are separated at an interval from each other to form a first flow channel. Each of the multiple heat exchange platy tubes includes a main body and at least one spacing wall. The main body has multiple second flow channels therein. The at least one spacing wall is located between two of the multiple second flow channels adjacent to each other. The air inlet and the air outlet communicate with the multiple second flow channels.

Abstract: An infrared thermometer includes a thermal conductor and a thermal adjuster to conduct suitable thermal flux into the sensor unit. A thermal conductive bushing is also mounted under the bottom of the sensor unit and touching the thermal conductor. The thermal fluxes conducting to the upper portion and the lower portion of the sensor unit are thus balanced suitably and quickly to remove the thermal noise and help the thermometer maintaining precise measurements from infrared radiation of the target.
