Abstract
Description
Technical Field
[0001] The utility model relates to the technical fields of machinery and electricity, in particular to a power cabinet for a detection wheel frame with optimized heat dissipation. Background Art
[0002] The heating power cabinet of the detection wheel frame is an important device installed on the flaw detection vehicle to supply power to the heat tracing system of the detection wheel frame. Its main functional components are: a transformer, a temperature controller, and a solid-state relay. Due to the narrow space on the vehicle and considering the safety of personnel operation, it is necessary to manufacture a cabinet body to safely place the transformer. Although the transformer will normally generate a certain amount of heat during operation, its influence on the ambient temperature basically does not affect the normal operation of the transformer itself. Therefore, natural cooling is generally adopted without additional heat dissipation settings and isolation settings. However, since the solid-state relay itself has relatively high requirements for the ambient temperature (operating temperature < 40°C), the solid-state relays installed in the same cabinet often fail due to the increase in ambient temperature caused by the operation of the transformer, such as overload and short circuit.
[0003] In view of the above situation that needs to be optimized, a solution is now proposed for the ambient temperature around the solid-state relay, and a power cabinet for a detection wheel frame with optimized heat dissipation is disclosed, which can improve the cabinet body structure and achieve rapid heat dissipation inside at the same time, so that the temperature around the temperature-sensitive components is controlled within 35°C. Summary of the Utility Model
[0004] The purpose of the utility model is to propose a power cabinet for a detection wheel frame with optimized heat dissipation, which can improve the cabinet body structure and form an active circulation heat dissipation system. The combination of the two enables the temperature around the temperature-sensitive components to be controlled within 35°C and can quickly dissipate the heat inside the cabinet.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A power cabinet for a detection wheel frame with optimized heat dissipation includes a cabinet body, an operation panel, a solid-state relay, a bakelite heat insulation board, a holding member, a transformer, lock screws, and heat dissipation fans. The operation panel is arranged at the front end of the cabinet body, and various function buttons are distributed thereon. The holding member is horizontally arranged in the middle section of the cabinet body. The bakelite heat insulation board is installed on the holding member. At the same time, the solid-state relay is placed at the center of the top surface of the bakelite heat insulation board. The transformer is installed below the holding member. The lock screws pass through the back panel of the cabinet body and are fixed at the rear of the transformer. There are two heat dissipation fans, which are symmetrically arranged up and down on the back panel of the cabinet body.
[0007] Furthermore, the cabinet body includes a top plate, a handle, ventilation holes, and corner plates. The top plate covers the top of the cabinet body through threaded connection. The handle is installed on the upper parts of the two side plates of the cabinet body. The ventilation holes are evenly arranged on the lower parts of the two side plates of the cabinet body. The corner plates are arranged on the outer sides of the four lower corners of the cabinet body.
[0008] Further, the holding member includes a right-angle bar and a holding plate. The right-angle bar is welded to the middle of the inner side wall of the cabinet body, and the vertical parts of the holding plate and the right-angle bar are connected together by threads.
[0009] In summary, the beneficial technical effects of the present utility model are as follows:
[0010] 1. By adopting the holding member, the cabinet body is divided into upper and lower layers. The transformer is installed in the lower layer of the cabinet body, and temperature-sensitive components such as solid-state relays are installed in the upper layer of the cabinet body, improving the cabinet body structure and controlling the temperature around the temperature-sensitive components in the upper layer of the box within 35°C.
[0011] 2. The bakelite heat insulation board is selected, and the heat insulation board made of a material with a relatively low thermal conductivity (bakelite: 0.25 W / m·K) is used to physically isolate the temperature-sensitive components from the heat source, reducing the influence of the heat source on the temperature-sensitive components.
[0012] 3. The cooling fan is applied and ventilation holes are designed at appropriate positions on the cabinet body to form an active circulation cooling system, quickly dissipating the internal temperature of the cabinet body to ensure that the temperature around the temperature-sensitive components is within a reasonable and controllable range.

[0017] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0018] A power cabinet for a detection wheel bracket with optimized heat dissipation disclosed by the utility model includes a cabinet body 1 and an operation panel 2. The operation panel 2 is arranged at the front end of the cabinet body 1, on which various function buttons are distributed. The cabinet body 1 includes a top plate 11, a handle 12, ventilation holes 13 and corner plates 14. Among them, the top plate 11 is covered on the top of the cabinet body 1 through threaded connection, which can prevent dust from entering the cabinet body 1. The handle 12 is installed on the upper parts of the two side plates of the cabinet body 1, which is convenient for the movement of the power cabinet for the detection wheel bracket. The ventilation holes 13 are evenly arranged at the lower parts of the two side plates of the cabinet body 1, which can quickly dissipate heat inside the cabinet body 1 to ensure that the temperature around the temperature-sensitive components is at a relatively low level and effectively protect the components. The corner plates 14 are arranged on the outer sides of the four corners of the lower half of the cabinet body 1, which helps to stabilize the power cabinet for the detection wheel bracket. Specifically, see Figure 1 .
[0019] The above-mentioned power cabinet for the detection wheel bracket further includes a solid-state relay 3, a bakelite heat insulation board 4, a holding member 5, a transformer 6, a locking nail 7 and a cooling fan 8. Among them, the holding member 5 is arranged in the middle section inside the cabinet body 1, including a right-angle bar 51 and a holding plate 52. The right-angle bar 51 is welded to the middle part of the inner side wall of the side of the cabinet body 1, and the holding plate 52 is threadedly connected to the vertical parts of the two right-angle bars 51. The bakelite heat insulation board 4 is installed on the holding plate 52. At the same time, the solid-state relay 3 is placed at the center of the top surface of the bakelite heat insulation board 4. Among the holding member 5 and the bakelite heat insulation board 4, the holding member 5 divides the inside of the cabinet body 1 into two layers. The bakelite heat insulation board 4 is made of a material with a relatively low thermal conductivity (bakelite: 0.25 W / m·K). They can effectively physically isolate the temperature-sensitive components from the heat source and realize the control of the temperature around the temperature-sensitive components in the upper layer of the box body. The transformer 6 is installed below the holding member 5. The locking nail 7 passes through the back panel of the cabinet body 1 and is fixed to the rear of the transformer 6, so as to ensure the stable locking of the transformer 6. There are two cooling fans 8 symmetrically arranged up and down on the back panel of the cabinet body 1. The cooling fans 8, combined with the ventilation holes 13 mentioned above, constitute an active circulation heat dissipation system to further reduce the temperature inside the cabinet body 1. For details, see Figure 2 and Figure 3 shown.
