Description

Technical Field

[0001] This utility model relates to the technical field of flaw detector equipment, specifically a heat dissipation structure for a flaw detector. Background Technology

[0002] As an important device for detecting internal defects in materials, flaw detectors play a crucial role in many fields such as machinery manufacturing, aerospace, and automotive industries. However, during operation, the internal electronic components (such as transmitting circuits, receiving circuits, and display modules) and mechanical parts (such as transmission devices and probe drive mechanisms) of flaw detectors continuously generate heat.

[0003] Traditional flaw detectors typically employ simple ventilation holes for heat dissipation, relying solely on natural convection, resulting in low efficiency. As flaw detectors become increasingly powerful and efficient, they generate more and more heat, rendering traditional methods inadequate. Excessive heat buildup can degrade the performance of internal electronic components, shorten their lifespan, and even cause malfunctions, affecting the accuracy of test results. Furthermore, high temperatures can deform mechanical parts, reducing the detector's precision and stability. Therefore, a new heat dissipation structure for flaw detectors is proposed. Utility Model Content

[0021] 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.

[0022] Please see Figures 1-4 This utility model discloses a heat dissipation structure for a flaw detector, including a housing 1, a top exhaust box 2 fixedly connected to the top of the housing 1, a control board 3 fixedly connected to the front end of the top exhaust box 2, a heat dissipation groove 4 opened on the inner wall of the housing 1, and a mesh 5 fixedly connected to the front end of the housing 1, with the mesh 5 corresponding to the heat dissipation groove 4.

[0023] Multiple heat dissipation plates 6 are fixedly connected to the inner wall of the heat dissipation slot 4. Heat conduction blocks 7 are arranged alternately between the multiple heat dissipation plates 6. A fixing seat 8 is fixedly connected to one side of the outer wall of the multiple heat conduction blocks 7, and one end of the multiple heat conduction blocks 7 passes through the box body 1.

[0024] Specifically, the heat dissipation structure of this flaw detector uses a housing 1 as its basic framework, integrating a heat conduction and heat dissipation system consisting of heat dissipation slots 4, heat dissipation plates 6, and heat-conducting blocks 7; a liquid-assisted heat dissipation system consisting of spray pipes 10 and pump boxes 13; and an air convection heat dissipation system consisting of a top exhaust box 2, a cooling fan 19, and air ducts 16. These systems work together, employing multiple heat dissipation methods to rapidly dissipate heat from the inside of the flaw detector, ensuring stable operation. The heat dissipation slots 4, located on the inner wall of the housing 1, provide installation space for the heat dissipation components. Their shape and size are optimized according to the layout of the heat-generating components inside the flaw detector to ensure effective heat transfer to the heat dissipation slots 4. Multiple heat dissipation plates 6, fixedly connected to the inner wall of the heat dissipation slots 4, are made of high thermal conductivity metals such as aluminum or copper, and their surfaces undergo special treatment to increase the heat dissipation area and improve heat dissipation efficiency. The heat-conducting blocks 7, which are arranged in an alternating pattern among multiple heat sinks 6, are also made of highly thermally conductive materials. Their unique staggered layout allows them to make more full contact with the heat sinks 6, and quickly conduct the heat generated inside the flaw detector to the heat sinks 6.

[0025] In this embodiment, multiple heat-conducting blocks 7 and multiple heat dissipation plates 6 are located inside the heat dissipation groove 4, and spray pipes 10 penetrate both the upper and lower ends of the inner wall of the heat dissipation groove 4.

[0026] Specifically, one end of the heat-conducting block 7 penetrates through the housing 1 and is tightly connected to the heating components inside the flaw detector through the fixing seat 8, ensuring that heat can be directly and efficiently transferred to the heat-conducting block 7.

[0027] In this embodiment, a plurality of conductive blocks 9 are fixedly connected to the side of the fixed base 8 away from the heat-conducting block 7, and the plurality of conductive blocks 9 correspond to the heat-conducting block 7.

[0028] Specifically, multiple conductive blocks 9 are fixedly connected to the side of the mounting base 8 away from the heat-conducting block 7, which further enhances the heat conduction path, allowing the heat to be distributed more evenly on the heat sink 6 and the heat-conducting block 7, thereby improving the overall heat conduction efficiency.

[0029] In this embodiment, multiple spray nozzles 11 are provided on the outer walls of the two spray pipes 10, and a transmission conduit 12 is fixedly connected to one end of each of the two spray pipes 10. A pump box 13 is fixedly connected to the end of the two transmission conduits 12 away from the spray pipes 10. The pump box 13 is located at the bottom of the box body 1.

[0030] Specifically, spray pipes 10, extending through the upper and lower ends of both sides of the inner wall of the heat dissipation tank 4, have multiple spray nozzles 11 on their outer walls that can evenly spray liquid onto the surfaces of the heat dissipation plate 6 and the heat-conducting block 7. Two spray pipes 10 are connected to a pump box 13 located at the bottom of the housing 1 via a transmission conduit 12. The pump box 13 contains a miniature water pump and a liquid storage chamber. The miniature water pump delivers coolant, such as water or a special heat dissipation fluid, from the storage chamber through the transmission conduit 12 to the spray pipes 10, from which it is then sprayed out through the spray nozzles 11. The coolant flows and evaporates on the surfaces of the heat dissipation plate 6 and the heat-conducting block 7, carrying away a large amount of heat and further improving the heat dissipation effect. Simultaneously, the flow of coolant also cleans the surfaces of the heat dissipation plate 6 and the heat-conducting block 7, preventing the accumulation of dust and other impurities that could affect heat dissipation.

[0031] In this embodiment, the inner wall of the top exhaust box 2 is fixedly connected to the bottom fan box 17, the bottom of the bottom fan box 17 is fixedly connected to the mounting bracket 18, and the inner wall of the bottom fan box 17 is fixedly connected to both sides of the mounting bracket 18. Cooling fans 19 are fixedly connected to both sides of the mounting bracket 18.

[0032] Specifically, the top exhaust box 2 is fixed to the top of the housing 1, and two cooling fans 19 are fixedly installed in the bottom fan box 17 on its inner wall by a fixing bracket 18. The cooling fans 19 are high-speed, low-noise DC fans that can generate strong airflow.

[0033] In this embodiment, the top of the bottom fan box 17 is fixedly connected to the air duct 16, and both ends of the air duct 16 are fixedly connected to the air outlet guide groove 15.

[0034] Specifically, the air outlet guide grooves 15 connected to both ends of the air duct 16 at the top of the bottom fan box 17, and the air outlets 14 on both sides of the outer wall of the top exhaust box 2 together form an air circulation channel.

[0035] In this embodiment, air outlets 14 are fixedly connected to both sides of the outer wall of the top exhaust box 2.

[0036] Specifically, when the cooling fan 19 is working, it draws hot air from inside the flaw detector into the bottom fan housing 17, through the air duct 16 and the air outlet guide slot 15, and out through the air outlet 14. At the same time, cool air from outside enters the heat dissipation slot 4 through the mesh 5 on the front face of the housing 1, forming air convection. The mesh 5 not only ensures smooth airflow but also prevents dust and other impurities from entering the flaw detector, protecting the internal components.

[0037] The working principle and usage process of this utility model are as follows: When the flaw detector starts working, the heat generated by the internal heating components is first transferred to the heat-conducting block 7 through the conduction block 9. Since the heat-conducting block 7 and the heat sink 6 are arranged in an alternating and close contact, the heat is quickly transferred to the heat sink 6. At this time, the miniature water pump in the pump box 13 starts, and the coolant is transported to the spray pipe 10 through the transmission conduit 12, and evenly sprayed from the spray nozzle 11 onto the surface of the heat sink 6 and the heat-conducting block 7. After absorbing heat, the coolant partially evaporates into a gaseous state, carrying away a large amount of heat. The remaining coolant flows down along the surface of the heat sink 6 and the heat-conducting block 7 and can be recycled back to the storage chamber of the pump box 13 for reuse. At the same time, the cooling fan 19 in the top exhaust box 2 starts, and the strong suction force draws the hot air inside the flaw detector into the bottom fan box 17 through the heat sink 4. The hot air passes through the air duct 16 and the air outlet guide groove 15, and is finally discharged from the air outlet 14. During the process of hot air being discharged, cold air from the outside enters the heat dissipation groove 4 through the mesh 5 on the front face of the housing 1 under the action of air pressure difference. It exchanges heat with the heat dissipation plate 6 and the heat conduction block 7, absorbs heat, becomes hot air and is discharged, forming a continuous air convection.
