An integrated heat dissipation duct structure for industrial CT equipment

Abstract

This invention discloses an integrated heat dissipation duct structure for industrial CT equipment, relating to the field of industrial CT equipment technology. It includes an industrial CT equipment body with a heat sink at its top for dissipating heat from the inside of the body. The side wall of the industrial CT equipment body has a mounting groove. Because the first fixing frame is made of lead, it not only prevents heat leakage but also prevents radiation leakage to the outside of the industrial CT equipment body. The second fixing frame, in conjunction with a heat-conducting plate, increases the length of the heat-conducting channel, resulting in better heat conduction. The airflow from the blower exchanges heat between the airflow in the first and second channels, and the airflow exits through the central vent of the third ventilation duct, thereby accelerating the airflow within the second channel and rapidly dissipating heat with the help of the heat sink.

Description

Technical Field

[0001] This invention relates to the field of industrial CT equipment technology, specifically to an integrated heat dissipation duct structure for industrial CT equipment. Background Technology

[0002] Industrial CT, relying on X-ray tomography technology, can complete full-size non-destructive scanning without disassembling or damaging parts. The equipment can accurately detect internal defects in castings such as porosity, cracks, looseness, and weld voids, quantitatively calculating defect size and porosity. It can also achieve micron-level three-dimensional dimensional measurement of hidden cavities and complex irregular structures, overcoming the limitations of coordinate measuring machines (CMMs). Widely used in quality inspection of automotive die-cast parts, aerospace blades, 3D printed parts, and electronic components, it is a key piece of equipment for precision manufacturing non-destructive testing, reverse modeling, and incoming material quality control. The entire machine is equipped with a lead-lined protective chamber, ensuring compliant and controllable radiation safety. According to Chinese patent CN214429930U, a heat dissipation structure for an industrial CT device is disclosed. The technical solution includes a heat dissipation fin structure, a heat dissipation copper pipe, a heat dissipation fan mounting plate, a heat dissipation fan, and an exhaust cavity. The heat dissipation fan is evenly installed on the side surface of the heat dissipation fan mounting plate from top to bottom, and the exhaust cavity is threaded to the right side surface of the heat dissipation fan mounting plate. It can be seen that industrial CT uses heat dissipation fins, heat dissipation copper pipes, etc. for heat dissipation. However, the heat dissipation pipes of industrial CT equipment do not adopt a labyrinth shielding structure, and the ventilation openings are mostly in the form of a grid. The radiation generated by the industrial CT equipment will be mixed with the hot air. Some of the radiation carried by the airflow will be discharged from the radiator with the hot air, thus causing radiation leakage. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated heat dissipation duct structure for industrial CT equipment to solve the problems mentioned in the background art: the heat dissipation duct of industrial CT equipment does not adopt a labyrinth shielding structure and the ventilation openings are mostly in the form of grids. The radiation generated by industrial CT equipment will be mixed with the hot air, and some of the radiation carried by the airflow will be discharged from the radiator along with the hot air, thus causing radiation leakage.

The cross-sections of each fixing frame of the first fixing frame are the same, and the cross-sections of each fixing frame of the second fixing frame are the same. The shapes of the first fixing frame and the second fixing frame are both inverted "U" shapes. The air inlet end of the radiator is connected to the interior of the first channel at the top.

[0006] As a preferred embodiment of the present invention, a fixing plate is installed at each corner of the second fixing frame. The fixing plate is made of lead. The fixing plate at the top corner of the second fixing frame is used to block the top corner of the first channel. Wind baffles are installed at both ends of the bottom of the second fixing frame to prevent heat from flowing back from the bottom ends of the second fixing frame into the interior of the industrial CT equipment.

[0007] As a preferred embodiment of the present invention, a plurality of heat-conducting plates are mounted on the middle and bottom of the second fixed frame. The heat-conducting plates are V-shaped and made of copper. The heat-conducting plates are used to increase the length of the first channel and the length of the second channel. The two side edges of the heat-conducting plates are located inside the first channel, and the middle of the heat-conducting plates is located inside the second channel. The heat-conducting plates are used to transfer heat from the first channel to the interior of the second channel.

[0008] As a preferred embodiment of the present invention, V-shaped reserved grooves are provided at the middle and bottom of the second fixing frame. The reserved grooves of the second fixing frame are adapted to the shape of the heat-conducting plate. The heat-conducting plate passes through the interior of the reserved grooves of the second fixing frame. The intersection of the heat-conducting plate and the second fixing frame is treated by welding.

[0009] As a preferred embodiment of the present invention, each fixed frame of the first fixed frame and each fixed frame of the second fixed frame are fixed by fixing bolts. A middle block is installed in the middle of the second fixed frame. A ventilated cover is provided inside the first fixed frame and on both sides of the middle block. An adsorption filler is provided inside the ventilated cover. The adsorption filler is made of lead particles. Hot air from the top of the second fixed frame enters the ventilated cover. The adsorption filler is used to adsorb residual radiation in the airflow. The bottom of the radiator is fixed to the top of the ventilated cover.

[0010] As a preferred embodiment of the present invention, an airflow acceleration component is provided between the first fixed frame and the second fixed frame. The airflow acceleration component includes a blower, which is installed at the top center of the first fixed frame. A first ventilation pipe is provided at the air outlet of the first fixed frame and at the middle block. A second ventilation pipe and a third ventilation pipe are respectively installed on the outer wall and inside of the second channel. The second ventilation pipe is connected to the first ventilation pipe through a fourth ventilation pipe. The blower is used to accelerate the airflow inside the first channel and the second channel.

[0011] As a preferred technical solution of the present invention, a number of connectors are installed on the fixing plate at the top corner of the second fixing frame. The connectors are used to connect the fourth ventilation pipe and the second ventilation pipe. A number of ventilation holes are opened in the middle of the third ventilation pipe and inside the second channel. The airflow of the third ventilation pipe flows back from the second channel to the ventilation cover.

[0012] As a preferred embodiment of the present invention, the second ventilation pipe is arranged vertically outside the second fixed frame, and the third ventilation pipe is arranged horizontally inside the second fixed frame. The second and third ventilation pipes are arranged in a mesh pattern, and the second ventilation pipe passes through both sides of the heat-conducting plate.

[0013] As a preferred technical solution of the present invention, the airflow of the blower passes through the interior of the first ventilation pipe, the fourth ventilation pipe, the second ventilation pipe and the third ventilation pipe, and then the airflow flows back from the middle of the third ventilation pipe to the interior of the first fixed frame at the top.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The first fixed frame is equipped with a ventilation component. Since the first fixed frame is made of lead, which has low thermal conductivity and high radiation isolation efficiency, the first fixed frame can not only prevent heat from escaping but also prevent radiation from leaking to the outside of the industrial CT equipment. The V-shaped heat-conducting plate can conduct heat from the first channel to the interior of the second channel. With the cooperation of the second fixed frame and the heat-conducting plate, the length of the heat-conducting channel can be increased, thus improving the heat conduction effect of the heat-conducting plate. Equipped with an airflow acceleration component, the airflow discharged by the blower can exchange heat between the airflow inside the first and second channels, and the airflow is discharged from the middle vent of the third ventilation pipe, thereby accelerating the airflow inside the second channel and quickly dissipating heat with the help of the radiator.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0020] Example 1:

[0021] Please see Figure 1 - Figure 6As shown, an integrated heat dissipation duct structure for an industrial CT device includes an industrial CT device body 1. A radiator 2 is installed at the top of the industrial CT device body 1 to dissipate heat from inside the body 1. During operation, the industrial CT device body 1 dissipates heat internally and absorbs heat from within through the radiator 2. A mounting groove 5 is formed on the side wall of the industrial CT device body 1. A ventilation component 3 is installed inside the mounting groove 5. The ventilation component 3 includes a first fixing frame 31 and a second fixing frame 34. The first fixing frame 31 is installed inside the mounting groove 5, which determines the position of the first fixing frame 31. The first fixing frame 31 is made of lead and is used to reduce radiation leakage from the radiator 2. The lead first fixing frame 31 reduces radiation generated during operation of the industrial CT device. The second fixing frame 34 is made of copper and is used to transfer heat. The second fixing frame 34 is located inside the first fixing frame 31. A second channel 35 is formed between the fixed frames 34, and a first channel 32 is formed inside the first fixed frame 31. The lead material of the first fixed frame 31 is used to block heat inside the first fixed frame 31, and the copper material of the second fixed frame 34 is used to conduct heat from the first channel 32 to the inside of the second fixed frame 34. The heat sink 2 is used to dissipate the heat from the top of the first fixed frame 31 and the top of the second fixed frame 34. The heat generated inside the main body 1 of the industrial CT equipment first enters the first channel 32, and then the heat is confined inside the first fixed frame 31 by the lead material. The heat inside the first channel 32 is transferred to the inside of the second fixing frame 34 made of copper, and thus the heat is transferred from the inside of the second channel 35 to the heat sink 2. The combination of lead material of the first fixing frame 31 and copper material of the second fixing frame 34 can not only prevent radiation leakage, but also better transfer heat to the outside of the heat sink 2. Since the first fixing frame 31 is made of lead, which has low thermal conductivity and high radiation isolation efficiency, the first fixing frame 31 can not only prevent heat leakage, but also prevent radiation leakage to the outside of the industrial CT equipment body 1.

[0022] Please see Figure 3 - Figure 5As shown, both the first fixing frame 31 and the second fixing frame 34 are composed of several sets of fixing frames. The fixing frames of the first fixing frame 31 are welded together, and the fixing frames of the second fixing frame 34 are spliced ​​together. Thus, after the first fixing frame 31 is fixed, the fixing frames of the second fixing frame 34 can be fixed. The cross-sections of each fixing frame of the first fixing frame 31 are the same, and the cross-sections of each fixing frame of the second fixing frame 34 are the same. The fixing frames of the first fixing frame 31 and the fixing frames of the second fixing frame 34 can be spliced ​​together. The shape of the first fixing frame 31 and the shape of the second fixing frame 34 are both inverted "U" shapes. The air inlet end of the radiator 2 is connected to the inside of the first channel 32 at the top, thereby fixing the first fixing frame 31 and the second fixing frame 34 at the mounting groove 5, preventing the first fixing frame 31 and the second fixing frame 34 from deforming. The position or shape of the first fixing frame 31 and the second fixing frame 34 can be used to conduct heat.

[0023] Please see Figure 4 and Figure 5 As shown, each corner of the second fixed frame 34 is equipped with a fixing plate 37. The fixing plate 37 is made of lead. The fixing plate 37 at the top corner of the second fixed frame 34 is used to block the top corner of the first channel 32. The fixing plate 37 at the top corner of the second fixed frame 34 can prevent the airflow of the first fixed frame 31 from entering the top interior of the first fixed frame 31. The fixing plate 37 at the top corner of the second fixed frame 34 can not affect the airflow at the lower end of the first channel 32. Both ends of the bottom of the second fixed frame 34 are equipped with wind deflectors 33. The wind deflectors 33 are used to prevent heat from flowing back from the bottom ends of the second fixed frame 34 into the interior of the industrial CT equipment body 1. The wind deflectors 33 are welded to the ends of the second fixed frame 34 to prevent airflow containing radiation from entering the interior of the second channel 35.

[0024] Please see Figure 5 As shown, several heat-conducting plates 38 are mounted on the middle and bottom of the second fixed frame 34. The heat-conducting plates 38 are V-shaped and made of copper. The heat-conducting plates 38 are used to increase the length of the first channel 32 and the second channel 35, so that the airflow flows from the inside of the first channel 32 and the hot airflow is introduced into the inside of the second channel 35 by the heat-conducting plates 38. The shape of the heat-conducting plates 38 is conducive to quickly introducing the heat of the first channel 32 into the inside of the second channel 35. The two side edges of the heat-conducting plates 38 are located inside the first channel 32, and the middle of the heat-conducting plates 38 is located inside the second channel 35. The heat-conducting plates 38 are used to transfer the heat in the first channel 32 to the inside of the second channel 35. The airflow is transferred from the edge of the heat-conducting plates 38 to the middle of the heat-conducting plates 38, so that the airflow in the first channel 32 is introduced into the inside of the second channel 35.

[0025] Please see Figure 5As shown, the second fixing frame 34 has V-shaped reserved grooves at the middle and bottom. The reserved grooves of the second fixing frame 34 are adapted to the shape of the heat-conducting plate 38. The heat-conducting plate 38 passes through the reserved groove of the second fixing frame 34. The intersection of the heat-conducting plate 38 and the second fixing frame 34 is treated by welding. The heat-conducting plate 38 is inserted into the reserved groove of the second fixing frame 34 and then fixed at the second fixing frame 34. This facilitates the entry of heat from the first channel 32 into the second channel 35. The heat in the first channel 32 can be conducted to the interior of the second channel 35. With the cooperation of the second fixing frame 34 and the heat-conducting plate 38, the length of the heat conduction channel can be increased, thus improving the heat conduction effect of the heat-conducting plate 38.

[0026] Please see Figure 4 and Figure 5 As shown, each fixed frame of the first fixed frame 31 and each fixed frame of the second fixed frame 34 are fixed by fixing bolts 39. The fixing bolts 39 can be used to fix each fixed frame of the first fixed frame 31 and each fixed frame of the second fixed frame 34 together, thus fixing both the first fixed frame 31 and the second fixed frame 34 to the mounting groove 5. A middle block 36 is installed in the middle of the second fixed frame 34. Ventilation covers 310 are provided inside the first fixed frame 31 on both sides of the middle block 36. The interior of the ventilation covers 310 is provided with… The adsorption filler 311 is made of lead particles. Hot air from the top of the second fixed frame 34 enters the interior of the ventilated cover 310. The adsorption filler 311 is used to adsorb residual radiation in the airflow. The bottom of the radiator 2 is fixed to the top of the ventilated cover 310. The top of the first channel 32 and the top of the second channel 35 are connected to each other, so that the airflow inside the first channel 32 and the second channel 35 can enter the ventilated cover 310. Thus, the adsorption filler 311 inside the ventilated cover 310 can adsorb the trace amount of residual radiation in the airflow.

[0027] It should be noted that the industrial CT equipment body 1 generates heat during operation, causing the hot air from the industrial CT equipment body 1 to enter the ventilation components 3 on both sides. Specifically, the heat originates from the first channel 32 inside the first fixed frame 31, and then the heat inside the first channel 32 is conducted to the second channel 35 inside the second fixed frame 34 through the heat-conducting plate 38. Then, the airflow from the second channel 35 of the second fixed frame 34 enters the top of the first fixed frame 31. Since the first channel 32 at the top of the first fixed frame 31 and the second channel 35 at the top of the second fixed frame 34 are connected, the heat enters the adsorption filler 311 inside the vent hood 310. The adsorption filler 311 adsorbs the residual trace radiation, preventing a large amount of residual radiation from the heat discharged from the radiator 2. Since the materials of the first fixed frame 31 and the second fixed frame 34 can accelerate heat transfer, the use of the V-shaped copper heat-conducting plate 38 can increase the contact length of the airflow, which is more conducive to the heat entering the second channel 35 from the first channel 32, thus improving the efficiency of heat transfer.

[0028] Please see Figure 2 , Figure 7 - Figure 9 As shown, an airflow acceleration assembly 4 is provided between the first fixed frame 31 and the second fixed frame 34. The airflow acceleration assembly 4 includes a blower 41, which is installed at the top center of the first fixed frame 31. A first ventilation pipe 42 is provided at the air outlet of the first fixed frame 31 and at the middle block 36. Since the top of the first channel 32 and the top of the second channel 35 are connected, the operation of the blower 41 causes the air outlet to enter the interior of the first ventilation pipe 42. The airflow of the first ventilation pipe 42 enters the interior of each second ventilation pipe 43 and third ventilation pipe 44 through the fourth ventilation pipe 45. The outer wall and interior of the second channel 35 are respectively equipped with second ventilation pipes 43 and third ventilation pipes 44. The second ventilation pipe 43 is connected to the first channel 35 through the fourth ventilation pipe 45. The air ducts 42 are connected. The blower 41 is used to accelerate the airflow inside the first channel 32 and the second channel 35. The second ventilation duct 43 and the third ventilation duct 44 are arranged in an alternating manner, so that the second ventilation duct 43 absorbs the heat inside the first channel 32 and the third ventilation duct 44 absorbs the heat inside the second channel 35. The third ventilation duct 44 has a vent hole in the middle, so that the heat can enter the radiator 2 with the airflow of the third ventilation duct 44, and the heat dissipation effect is faster. The airflow discharged by the blower 41 can exchange heat with the airflow inside the first channel 32 and the second channel 35, and the airflow is discharged from the vent hole in the middle of the third ventilation duct 44, which can accelerate the airflow inside the second channel 35 and quickly dissipate the heat with the help of the radiator 2.

[0029] Please see Figure 7 - Figure 9As shown, several connectors 46 are installed at the fixing plate 37 at the top corner of the second fixing frame 34. The connectors 46 are used to connect the fourth ventilation pipe 45 and the second ventilation pipe 43. The fourth ventilation pipe 45 and the second ventilation pipe 43 are installed at the connectors 46 to prevent the third ventilation pipe 44 and the fourth ventilation pipe 45 from falling off. Several vent holes are opened in the middle of the third ventilation pipe 44 and inside the second channel 35. The airflow of the third ventilation pipe 44 flows back from the second channel 35 to the vent cover 310. The airflow discharged from the vent holes blows the heat flow in the second channel 35 to the radiator 2.

[0030] Please see Figure 7 - Figure 9 As shown, the second ventilation pipe 43 is vertically arranged outside the second fixed frame 34, and the third ventilation pipe 44 is horizontally arranged inside the second fixed frame 34. The second ventilation pipe 43 and the third ventilation pipe 44 are arranged in a mesh pattern. The second ventilation pipe 43 passes through both sides of the heat-conducting plate 38. The airflow of the blower 41 passes through the first ventilation pipe 42, the fourth ventilation pipe 45, the second ventilation pipe 43 and the interior of the third ventilation pipe 44. The airflow then flows back from the middle of the third ventilation pipe 44 to the interior of the first fixed frame 31 at the top. Since the second ventilation pipe 43 and the third ventilation pipe 44 are arranged in a mesh pattern, it is beneficial for the second ventilation pipe 43 and the third ventilation pipe 44 to absorb heat from different locations.

[0031] It should be noted that when the blower 41 operates, the air outlet enters the fourth ventilation pipe 45 and the second ventilation pipe 43 from the first ventilation pipe 42. The second ventilation pipe 43 and the third ventilation pipe 44 are arranged in a mesh pattern, which allows the second ventilation pipe 43 and the third ventilation pipe 44 to exchange heat inside the first channel 32 and the second channel 35, thereby accelerating the heat flow inside the first channel 32 and the second channel 35. Furthermore, the airflow discharged from the vent of the second ventilation pipe 43 carries the heat inside the second channel 35, thereby accelerating the heat from inside the second channel 35 into the top second channel 35. Under the action of the radiator 2, the heat is discharged relatively quickly.

[0032] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
