In the medical field, detectors such as CT machines or PET machines can detect the inside of a human body to check various indexes of the human body. Taking a CT machine as an example, it includes an X-ray tube assembly and a detector assembly. The detector assembly includes a detector that receives the X-ray signal and electronics, such as a scintillator, a photodiode, and an AD conversion device, that process the information read by the X-rays. Since the scintillator needs to operate at a relatively stable temperature, and the devices generate a large amount of heat during operation, it is necessary to perform heat dissipation and temperature control on the electronic devices in time.

At present, the heat dissipation of electronic devices mainly adopts an air cooling mode, specifically, a fan is arranged on a detector assembly and blows air into a detector so as to take away heat generated by the electronic devices. However, the heat dissipation effect of the heat dissipation method is not obvious due to the large length and width of the detector assembly. The defect that the temperature distribution of detector components at different positions is uneven due to uneven air outlet and easiness in enabling the detector components to generate temperature gradients, particularly scintillators, mainly exists. The nonuniform temperature distribution of the CT detector module system can cause inconsistent response of different detectors, thereby causing the abnormity of the CT detector module system and influencing the image quality.

In addition, when air cooling is used for heat dissipation, extra light sources can enter an air inlet and an air outlet of the detector system, so that the problem of artifacts of images of the detector occurs, and the image quality is poor.
