The invention discloses a water-cooling-based photoelectric detector packaging structure and packaging method. The packaging structure comprises a water-cooling plate unit and at least one detection module arranged on the water-cooling plate unit, wherein each detection module comprises a detector unit and a heat-conducting unit; one end of each heat-conducting unit is connected with the corresponding detector unit and the other end of the heat-conducting unit is connected with the water-cooling plate unit; each heat-conducting unit comprises a heat-conducting plate and an installation plate; each heat-conducting plate is fixedly connected with the corresponding installation plate; and a heat-conducting cavity is formed between each heat-conducting plate and the corresponding installation plate. The packaging method comprises the following steps of packaging single detection module, assembling the water-cooling plate unit and assembling all detection modules on the water-cooling plate unit. Through the structural design of the water-cooling plate unit, the detection unit and the heat-conducting unit, balanced transferring of the temperature can be achieved, so that the adopted photoelectric detector reaches the optimal working state, and equipment of using the photoelectric detector has better performance parameters.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a water-cooled photodetector packaging structure and a packaging method thereof. Background technique [0002] In medical technology, PET and other equipment will use some photodetectors for radiation measurement and detection. For example, SiPM (Silicon photomultiplier, silicon photomultiplier) is a new type of semiconductor detector. Its compact structure and high signal-to-noise ratio greatly improve the spatial resolution of PET equipment. [0003] Photodetectors are generally equipped with back-end circuits for signal processing calculations, which generally bring relatively large heat. However, these photodetectors are extremely sensitive to temperature and temperature changes. Therefore, certain cooling temperature control methods and packaging techniques must be used to achieve the temperature control requirements for normal operation, so that the photodetector...
