Description

Technical Field

[0001] This utility model belongs to the field of radiation detection technology, specifically relating to a portable radiation detector. Background Technology

[0002] Nuclear radiation detectors, also known as nuclear detection elements, are devices used to detect radiation rays. Commonly used ones include ionization chambers, counting tubes and scintillation counters, nuclear emulsion detectors, solid-state nuclear track detectors, and semiconductor detectors. These detection elements can measure radiation rays and their properties. Their principle mainly utilizes the various effects produced when rays interact with matter.

[0003] Existing radiation detectors generate heat during operation, and most of them use ventilation vents for heat dissipation. If proper heat dissipation is not provided, the equipment may overheat, affecting its normal operation and lifespan. Therefore, we propose a portable radiation detector. Utility Model Content

[0004] The purpose of this invention is to provide a portable radiation detector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable radiation detector, comprising a detector body, a display screen and control buttons on the front of the detector body, heat dissipation holes on the back of the detector body, a thermally conductive silicone pad, a thermally conductive copper sheet and a heat sink on the inner side of the heat dissipation holes, a first elastic locking block on the back of the detector body, a sliding groove on the back of the detector body, a slider on the inner side of the sliding groove, a protective cover on the top of the slider, and a second elastic locking block on the inner side of the protective cover.

[0006] Preferably, one side of the thermally conductive silicone pad is in contact with the internal heating element of the detector body, a thermally conductive grease layer is applied between the thermally conductive silicone pad and the thermally conductive copper sheet, and a heat sink is installed on top of the thermally conductive copper sheet.

[0007] Preferably, a first elastic block is fixedly installed on the back side of the detector body near the heat dissipation hole, and sliding grooves are provided on both sides of the back side of the detector body.

[0008] Preferably, a slider is slidably installed on the inner side of the groove, and the top of the slider is fixedly connected to the bottom side of the protective cover.

[0009] Preferably, a second elastic block is fixedly installed at one end of the bottom inner side of the protective cover, and the second elastic block and the first elastic block are elastically engaged.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By opening the protective cover and exposing the heat dissipation holes to the outside, the heat generated by the heat-generating components inside the detector body is absorbed by the thermally conductive silicone pad. Then, the thermally conductive silicone grease layer transfers the heat to the surface of the thermally conductive copper sheet above. The heat of the thermally conductive copper sheet itself is absorbed by the heat sink above. Finally, the heat on the surface of the heat sink is carried away by the outside airflow, thereby improving the heat dissipation efficiency of the detector body and extending its service life.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a portable radiation detector, including a detector body 1. The front of the detector body 1 is provided with a display screen 2 and control buttons 3. The back of the detector body 1 is provided with heat dissipation holes 4. The inner side of the heat dissipation holes 4 is provided with a thermally conductive silicone pad 5, a thermally conductive copper sheet 7 and a heat sink 8. The back of the detector body 1 is provided with a first elastic locking block 9. The back of the detector body 1 is provided with a sliding groove 10. The inner side of the sliding groove 10 is provided with a slider 11. The top of the slider 11 is provided with a protective cover 12. The inner side of the protective cover 12 is provided with a second elastic locking block 13.

[0018] Specifically, one side of the thermally conductive silicone pad 5 contacts the internal heating element of the detector body 1. A thermally conductive silicone grease layer 6 is applied between the thermally conductive silicone pad 5 and the thermally conductive copper sheet 7. A heat sink 8 is installed on top of the thermally conductive copper sheet 7. A first elastic block 9 is fixedly installed on the back side of the detector body 1 near the heat dissipation hole 4. Slide grooves 10 are provided on both sides of the back side of the detector body 1. A slider 11 is slidably installed on the inner side of the slide groove 10. The top of the slider 11 is fixedly connected to one side of the bottom of the protective cover 12. A second elastic block 13 is fixedly installed on one end of the bottom inner side of the protective cover 12. The second elastic block 13 and the first elastic block 9 are elastically engaged.

[0019] In this embodiment, after prolonged use, the detector body 1 accumulates a significant amount of heat. Pushing the protective cover 12 towards the bottom of the detector body 1 causes the protective cover 12 to move the slider 11 within the slide groove 10, thereby improving the stability of the protective cover 12 during movement. The movement of the protective cover 12 exposes the heat dissipation hole 4 to the outside. The thermally conductive silicone pad 5 absorbs the heat generated by the heating element inside the detector body 1. The thermally conductive silicone grease layer 6 transfers the heat absorbed by the surface of the thermally conductive silicone pad 5 to the surface of the thermally conductive copper sheet 7 above. The heat of the thermally conductive copper sheet 7 itself is absorbed by the heat sink 8 above. Finally, the heat on the surface of the heat sink 8 is carried away by the outside airflow, thereby improving the heat dissipation efficiency of the detector body 1 and extending its service life. By setting the second elastic locking block 13 to be elastically engaged with the first elastic locking block 9, the protective cover 12 can firmly seal and protect the outside of the heat dissipation hole 4 after use, facilitating subsequent use.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
