Description

Technical Field

[0001] The present invention relates to the technical field of vacuum radiators, and in particular to a vacuum radiator for a new type of flexible circuit board. Background Art

[0002] A flexible circuit board refers to a printed circuit board made of substrates such as polyimide. In order to ensure the effectiveness of the long-term use of the flexible circuit board, a radiator is often used around the flexible circuit board.

[0003] However, for the heat dissipation structure of the flexible circuit board by conventional means, generally only heat sinks are provided on the outer part of the circuit board for auxiliary heat dissipation, and its heat dissipation efficiency is low; the vacuum radiator mainly uses a highly efficient heat-conducting medium, superconducting liquid, to replace traditional water, and uses the superconducting liquid to circulate and transfer heat in a vacuum-sealed pipeline to dissipate heat and cool the outside of the circuit board. However, the air flow is relatively stable at the position between the circuit board and the radiator, and it is easy to cause heat accumulation and difficult to quickly dissipate when the local temperature of the circuit board is high. Therefore, a new type of heat dissipation device is designed to improve the instantaneity and heat dissipation effect of heat dissipation. Summary of the Invention

[0004] Based on the technical problems in the background art, the present invention proposes a vacuum radiator for a new type of flexible circuit board.

[0005] A vacuum radiator for a new type of flexible circuit board proposed by the present invention includes a mounting rack and a vacuum radiator main body. A flexible circuit board main body is arranged on the mounting rack; an installation cavity with two open ends is arranged in the middle of the mounting rack, and the vacuum radiator main body is provided with two fixed pipes, and the two fixed pipes are respectively located at both ends of the installation cavity. A plurality of extension pipes communicate with the outer wall of the fixed pipe in the direction towards the middle of the mounting rack, and the extension pipes on the two fixed pipes are arranged at intervals and staggered; two groups of driving components are arranged in the mounting rack, and the two groups of driving components respectively drive the two fixed pipes to rotate around their own axes; through grooves are opened at the positions of the top of the mounting rack corresponding to the fixed pipes and the extension pipes.

[0006] Preferably, the two groups of driving components are respectively arranged on both sides of the installation cavity. The driving component is provided with an electric guide rail fixed to the inner wall of the bottom of the installation cavity, and the electric guide rail is arranged parallel to the extension pipe. A connecting frame is connected to the electric guide rail, and a vertically extending driving block is installed on the connecting frame.

[0007] Preferably, one end of the extension pipe away from the fixed pipe is provided with a head, and the outer diameter of the head gradually decreases in the direction away from the fixed pipe. The top end of the driving block is in sliding contact with the outer wall of the bottom of the extension pipe and the outer wall of the bottom of the head. When the extension pipe is placed horizontally, the position of the bottom of the head away from the fixed pipe just contacts the top end of the driving block.

[0008] Preferably, a plurality of cushion blocks are fixed at both edge positions of the outer wall of the top of the mounting frame, and the bottom of the flexible circuit board body abuts against the top of the cushion blocks.

[0009] Preferably, a plurality of capillary tubes extending inward are arranged on the outer wall of the extension tube. The capillary tubes are distributed at the top, bottom and both sides of the extension tube, and are vertically arranged between adjacent two capillary tubes.

[0010] Preferably, openings corresponding to the capillary tubes are arranged on the extension tube, the openings are arranged to open outward, and the inner diameter of the openings gradually decreases in the direction towards the inside of the extension tube.

[0011] Preferably, positioning tubes are installed at positions on both sides of the mounting frame corresponding to the ends of the fixed tubes, and the ends of the fixed tubes are rotatably connected to the positioning tubes.

[0012] Preferably, the positioning tube is arranged in a U-shaped structure. One end of the positioning tube away from the fixed tube extends into the installation cavity from below the fixed tube. Communication tubes are arranged on both sides of the installation cavity, and both ends of the communication tubes are communicated with the bottom ends of the two positioning tubes on the same side of the mounting frame.

[0013] Preferably, the communication tubes are inclined in both the horizontal and vertical directions. One end of the communication tube close to the driving block at the same side is arranged as the bottom, and the other end of the communication tube is arranged as the top. In the vertical direction, the bottom is below the top, and in the horizontal direction, the bottom is on the side close to the center of the mounting frame of the top.

[0014] The beneficial effects in the present invention are as follows:

[0015] 1. In the present invention, through the driving assembly, the two fixed tubes respectively reciprocally deflect around their own axes, so that the distances between various positions at the top of a single extension tube and the flexible circuit board body are differentially changed, and the air flow between the flexible circuit board body and the extension tube flows along the direction of the extension tube, so that the local high-temperature air flow of the flexible circuit board body is quickly dispersed during the swinging process of the two fixed tubes and the corresponding extension tubes, so as to achieve rapid cooling.

[0016] 2. In the present invention, through the capillary tubes vertically arranged adjacent to each other in the extension tube and the swinging of the extension tube, the flow impact effect of the cooling medium in the extension tube is improved, and through the openings corresponding to the capillary tubes opening outward, the dispersion effect of the air flow on the outer wall of the extension tube is increased, so as to improve the heat exchange and cooling effect between the cooling medium inside the extension tube and the external hot air.

[0017] 3. In the present invention, through the inclined arrangement of the communication tubes at both sides and the circulation of the cooling medium caused by the swinging of the extension tube, the flow dispersion effect of the cooling medium is improved. Description of the Drawings

Detailed implementation method

[0028] Example 1: Refer to Figures 1-8, a novel vacuum radiator for flexible circuit boards, comprising a mounting frame 1 and a vacuum radiator main body 3. A flexible circuit board main body 2 is arranged on the mounting frame 1. An installation cavity with openings at both ends is arranged in the middle of the mounting frame 1. The vacuum radiator main body 3 is provided with two fixed tubes 5, and the two fixed tubes 5 are respectively located at both ends of the installation cavity. The fixed tubes 5 are horizontally extended between the two sides of the mounting frame 1. A plurality of extension tubes 6 are communicated with the outer wall of the fixed tube 5 towards the middle of the mounting frame 1. The extension tubes 6 are perpendicular to the fixed tubes 5. One end of the extension tube 6 far from the fixed tube 5 is sealed. The extension tubes 6 on the two fixed tubes 5 are arranged at intervals and staggered. There is a gap between the bottoms of the fixed tubes 5 and the extension tubes 6 and the bottom inner wall of the installation cavity. Two groups of driving components 8 are arranged in the mounting frame 1. The two groups of driving components 8 respectively drive the two fixed tubes 5 to rotate around their own axes. One group of driving components 8 corresponds to one fixed tube 5. Through grooves 101 are opened at the positions of the mounting frame 1 corresponding to the fixed tubes 5 and the extension tubes 6 at the top. The flexible circuit board main body 2 is installed at the top position of the mounting frame 1. In the normal state, the extension tubes 6 outside the two fixed tubes 5 are staggered and kept horizontally placed. During use, the fixed tubes 5 and the corresponding plurality of extension tubes 6 are filled with a cooling medium to perform heat exchange and cooling treatment on the outside of the flexible circuit board main body 2. During the working process, the two fixed tubes 5 are respectively reciprocally deflected around their own axes through the driving components 8, and the extension tubes 6 can be rotated upward from the through groove 101 position above the mounting frame 1, so that the distances between the top positions of each single extension tube 6 and the flexible circuit board main body 2 are differently changed, and the air flow between the flexible circuit board main body 2 and the extension tubes 6 flows along the direction of the extension tubes 6. And through the reverse effect of the rotation of the adjacent extension tubes 6, the air flow at the bottom of the flexible circuit board main body 2 flows in the extending direction of the fixed tubes 5, so that the local high-temperature air flow of the flexible circuit board main body 2 is quickly dispersed during the swinging process of the two fixed tubes 5 and the corresponding extension tubes 6 to achieve rapid cooling. And by using the softness of the base material of the flexible circuit board main body 2, the base material can shake along with the air flow movement, so as to further improve the movement and dispersion effect of the air flow around the flexible circuit board main body 2, thereby improving the immediacy of heat dissipation and enhancing the heat dissipation effect. At the same time, the flow effect of the internal cooling medium is improved by the reciprocating swing of the extension tubes 6 around the axis of the fixed tubes 5, so as to further improve the heat exchange and cooling efficiency.

[0029] In the present invention, two sets of driving components 8 are respectively arranged on both sides of the installation cavity. The driving component 8 is provided with an electric guide rail 9 fixed to the inner wall of the bottom of the installation cavity. The electric guide rail 9 is arranged parallel to the extension pipe 6. A connecting frame 10 is connected to the electric guide rail 9. A vertically extending driving block 11 is installed on the connecting frame 10. One end of the extension pipe 6 away from the fixed pipe 5 is provided with a head 601. The outer diameter of the head 601 gradually decreases in the direction away from the fixed pipe 5. The top end of the driving block 11 is in sliding contact with the outer wall of the bottom of the extension pipe 6 and the outer wall of the bottom of the head 601. When the extension pipe 6 is horizontally placed, the position of the bottom of the head 601 away from the fixed pipe 5 just contacts the top end of the driving block 11. The two electric guide rails 9 drive the two connecting frames 10 to move alternately in opposite directions, and the two connecting frames 10 extend in different directions towards both ends of the mounting frame 1, so that the driving blocks 11 in the two driving components 8 respectively contact the ends of the extension pipes 6 outside the two different fixed pipes 5. Driven by the electric guide rail 9, when the driving block 11 moves towards the middle position of the mounting frame 1 along with the connecting frame 10, the driving block 11 approaches the extension pipe 6 along the inclined surface of the outer wall of the head 601, and the extension pipe 6 is tilted to drive the fixed pipe 5 to rotate. Then, when the driving block 11 moves towards the fixed pipe 5 at the bottom of the extension pipe 6, the inclined angle of the extension pipe 6 is gradually increased by the support of the driving block 11 at the bottom until the position of the head 601 starts to deflect upwards out of the mounting frame 1. When the electric guide rail 9 drives the driving block 11 to move away from the fixed pipe 5, the extension pipe 6 will be gradually flattened. Thus, the reciprocating deflection of the fixed pipe 5 and the extension pipe 6 is realized, and the stability of the extension pipe 6 in the horizontal state and during the rotation process is improved by using the driving block 11; at the same time, by using the reciprocating movement of the driving block 11 in the installation cavity and at the bottom of the extension pipe 6, the air flow movement at the bottom of the installation cavity is increased, and the overall heat dissipation and cooling efficiency of the vacuum radiator body 3 is further enhanced.

[0030] In the present invention, a plurality of cushion blocks 4 are fixed to both side edge positions of the outer wall of the top of the mounting frame 1. The bottom of the flexible circuit board body 2 abuts against the top of the cushion blocks 4, so that the area of the bottom of the flexible circuit board body 2 corresponding to the extension pipe 6 is suspended, and direct contact with the outer wall shell at the top of the mounting frame 1 is avoided, the flow space of the air flow is increased to improve the heat dispersion effect, and the rotation space of the extension pipe 6 is increased to further improve the heat dissipation efficiency and the cooling effect.

[0031] In the present invention, a plurality of capillary tubes 7 extending inwards are arranged on the outer wall of the extension pipe 6. The capillary tubes 7 are distributed at the top, bottom and both sides of the extension pipe 6, and are vertically arranged between two adjacent capillary tubes 7. Through the arranged extension pipe 6 and the capillary tubes 7 distributed in the extension pipe 6, the outer wall contact area is increased to improve the heat exchange and cooling effect, and through the cooperation of the adjacent vertically arranged capillary tubes 7 in the extension pipe 6 and the swing of the extension pipe 6, the flow impact effect of the cooling medium in the extension pipe 6 is improved, so as to improve the heat exchange and cooling effect between the cooling medium inside the extension pipe 6 and the external hot air.

[0032] In the present invention, an opening is provided at a position corresponding to the capillary tube 7 outside the extension tube 6. The opening is arranged to open outwards, and the inner diameter of the opening gradually decreases towards the inside of the extension tube 6. Thus, during the reciprocating swing of the extension tube 6, the opening of the capillary tube 7 corresponding to the outward opening will increase the dispersion effect of the airflow on the outer wall of the extension tube 6, so as to further disperse the airflow during the swing of the extension tube 6 and achieve uniform and rapid heat exchange and cooling.

[0033] Embodiment 2: Embodiment 2 includes all the structures and methods of Embodiment 1. Refer to Figures 1-9 , a vacuum radiator for a new type of flexible circuit board. On the basis of Embodiment 1, positioning tubes 12 are installed at positions corresponding to the ends of the fixed tubes 5 on both sides of the mounting frame 1. The ends of the fixed tubes 5 are rotatably connected to the positioning tubes 12. The positioning tubes 12 are arranged in a U-shaped structure. One end of the positioning tube 12 away from the fixed tube 5 extends into the installation cavity from below the fixed tube 5. Connecting tubes 13 are arranged on both sides of the installation cavity. A support frame 14 is fixed between the connecting tube 13 and the inner wall of the bottom of the installation cavity. The two ends of the connecting tube 13 are communicated with the bottoms of two positioning tubes 12 on the same side of the mounting frame 1. The connecting tube 13 is inclined in both the horizontal and vertical directions. One end of the connecting tube 13 close to the driving block 11 at the same side position is set as the bottom, and the other end of the connecting tube 13 is set as the top. In the vertical direction, the bottom is below the top, and in the horizontal direction, the bottom is on the side close to the center of the mounting frame 1 of the top, so that the two fixed tubes 5 and multiple extension tubes 6 are internally communicated and integrated through the positioning tubes 12 and the connecting tubes 13, and the flow and cooling of the cooling medium can be actively realized by connecting an external pipeline and a pump to the positioning tubes 12 at fixed positions; during use, due to the inclined setting of the connecting tubes 13 at both sides, combined with the circulation of the cooling medium caused by the swing of the extension tubes 6, the flow dispersion effect of the cooling medium is improved; and because the driving blocks 11 on the driving components 8 at both sides are respectively located at both ends of the installation cavity, the inclined directions of the connecting tubes 13 at both sides are set in the opposite direction, and the connecting tube 13 straddles the adjacent extension tubes 6 and the adjacent extension tubes 6 deflect in the opposite direction, thereby further improving the airflow movement around the connecting tube 13 to improve the heat exchange and cooling efficiency of the overall vacuum radiator body 3.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
