Description

Technical Field

[0001] This invention relates to the technical field of circuit boards. More specifically, this invention relates to an HDI circuit board that facilitates heat dissipation. Background Technology

[0002] Existing Chinese patent: A fast-heat dissipation HDI circuit board (CN207783246U). The fast-heat dissipation HDI circuit board provided by this invention can effectively improve heat dissipation and enhance the insulation, waterproofing, wear resistance, and flame retardant properties of the HDI circuit board. However, when it dissipates heat from the HDI circuit board through convective air, the convective air only flows through the ventilation holes. That is, the heat exchange surface between the convective air and the HDI circuit board is only the inner ring surface of the ventilation holes, resulting in low heat exchange efficiency and thus an insignificant heat dissipation effect. At the same time, there is no fire extinguishing structure on the HDI circuit board, and the circuit board may spontaneously combust when it overheats, posing a significant safety hazard.

[0033] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0034] Implementation Plan 1

[0035] An HDI circuit board that facilitates heat dissipation, such as Figure 1-8As shown, the circuit includes a first circuit board 1, a second circuit board 2, a third circuit board 3, a fourth circuit board 4, a first copper tube 5, a first test pad 6, a second copper tube 7, a second test pad 8, a third copper tube 9, a cooling component, and a blower component.

[0036] The cooling assembly includes a pipe 201, an isolation unit, a first fire extinguishing unit, and a second fire extinguishing unit; a pipe 201 is fixedly connected between the left and right sides of the first circuit board 1, the second circuit board 2, the third circuit board 3, and the fourth circuit board 4; three isolation units are connected between two pipes 201, and the three isolation units are arranged intersecting with the first circuit board 1, the second circuit board 2, the third circuit board 3, and the fourth circuit board 4; a first fire extinguishing unit is connected to the inside of each of the three isolation units; a second fire extinguishing unit is connected to the inside of each of the three isolation units, and the three second fire extinguishing units are located inside the adjacent first fire extinguishing units; three grooves 91 are equally spaced on the left and right sides of the pipe 201.

[0037] The upper isolation unit includes a hollow plate 202, a first spacer 203, a second spacer 204, and a third spacer 205; the hollow plate 202 connects the upper sides of the two pipes 201; the hollow plate 202 is insulating; the upper side of the hollow plate 202 is fixedly connected to the fourth circuit board 4; the lower side of the hollow plate 202 is fixedly connected to the third circuit board 3; the first spacer 203 is welded to the middle of the inner side of the hollow plate 202; both pipes 201 are fixedly connected to the first spacer 203; a second spacer 204 is welded to the front and rear inner sides of the hollow plate 202; the two second spacers 204 are fixedly connected to the two pipes 201 respectively; a third spacer 205 is fixedly connected to the left and right inner sides of the hollow plate 202; the two third spacers 205 are fixedly connected to the adjacent pipes 201 respectively.

[0038] The first fire extinguishing unit located at the top includes a first connecting block 206, a first elastic element 207, and a first heat-melting element 208; twelve first connecting blocks 206 are fixedly connected to the inner left and inner right sides of the hollow plate 202; through holes are opened in the first connecting blocks 206; every three first connecting blocks 206 form a group, and a first elastic element 207 is fixedly connected to each group of first connecting blocks 206; the first elastic element 207 is arc-shaped; a streamlined groove is opened on the side of the first elastic element 207 away from the first connecting block 206; eight first elastic elements 208... All components 207 are in contact with the hollow plate 202; each of the eight first elastic components 207 has a first hot melt component 208 fixedly connected to both ends; the four first hot melt components 208 located in the middle are respectively fixedly connected to the adjacent third spacer 205; the twelve first hot melt components 208 located on the outer side are all fixedly connected to the hollow plate 202; a first chamber 92 is formed between the hollow plate 202, the third spacer 205, the first elastic components 207 and the first hot melt components 208, and the first chamber 92 is filled with fire extinguishing agent; the first elastic component 207 is an alloy elastic sheet.

[0039] The second fire extinguishing unit located at the top includes a second connecting block 209, a second elastic element 2010, and a second heat-fused element 2011; six second connecting blocks 209 are welded to each of the two second partition bars 204; a through hole is opened in the middle of the second connecting block 209; every three second connecting blocks 209 form a group, and a second elastic element 2010 is fixedly connected to each group of second connecting blocks 209; a streamlined groove is opened on the side of the second elastic element 2010 away from the second connecting block 209; four Each of the second elastic elements 2010 is in contact with the hollow plate 202; each of the four second elastic elements 2010 has a second hot melt element 2011 fixedly connected to both ends; the eight second hot melt elements 2011 are respectively fixedly connected to the adjacent second spacers 204; a second chamber 93 is formed between the hollow plate 202, the second spacers 204, the second elastic elements 2010 and the second hot melt elements 2011, and the second chamber 93 is filled with fire extinguishing agent; the second elastic element 2010 is an alloy elastic sheet.

[0040] During preparation, the blower assembly supplies air into the left-side pipe 201. The air flows into the hollow plate 202 through the groove 91 on the right side of the left-side pipe 201, and flows into the cavities on both sides of the first spacer 203, before being discharged downwards from the right-side pipe 201. Simultaneously, some air flows into the hollow plate 202 through the groove 91 on the left side of the left-side pipe 201, and flows to the front and rear sides of the third spacer 205, then flows to the right to the opposite sides of the two second spacers 204, before being discharged downwards from the right-side pipe 201. This allows air to flow inside the hollow plate 202, and the third circuit board 3 and the fourth circuit board... 4. The heat generated during operation is conducted to the hollow plate 202. The air flowing inside the hollow plate 202 carries away the heat, achieving a heat dissipation effect. During use, air is supplied to the hollow plate 202, which serves as an insulating board. The airflow carries away the heat conducted from the third circuit board 3 to the hollow plate 202, achieving a heat dissipation effect. Compared with the existing circuit boards that use ventilation holes for heat dissipation, this greatly increases the heat exchange area and avoids the disadvantage of the existing circuit boards having an insignificant heat dissipation effect. At the same time, the special layout of the first partition 203, the second partition 204, and the third partition 205 makes the air flow evenly inside the hollow plate 202, making the heat dissipation of the third circuit board 3 more uniform.

[0041] During the heat dissipation process, when air flows into the inner side of the hollow plate 202 through the groove 91 on the left side of the pipe 201 located on the left, the air on the left side of the hollow plate 202 eventually needs to move towards the pipe 201 located on the right. That is, the air rushes towards the inner edge of the hollow plate 202 and then experiences a backflow phenomenon, which generates noise. At this time, the first elastic member 207 guides the air that is about to be backflow. Since the first elastic member 207 is arc-shaped, the air smoothly backflows along the arc surface, greatly reducing the noise generation. In use, the first elastic member 207 is used to smoothly guide the air that is about to be backflow to reduce the noise generation.

[0042] When the third circuit board 3 spontaneously combusts, the resulting high temperature melts the first heat-fused component 208, causing the first elastic component 207 to spring back and retract, i.e., the two ends of the first elastic component 207 come together. At this time, air flows into the first chamber 92 along the side of the third partition 205, blowing out the extinguishing agent. Simultaneously, the resulting high temperature melts the second heat-fused component 2011, causing the second elastic component 2010 to spring back and retract, i.e., the two ends of the second elastic component 2010 come together. At this time, air... Gas flows along the second partition 204 into the second chamber 93 and blows out the extinguishing agent, thereby causing the extinguishing agent to be sprayed from the pipe 201 on the right into the casing for fire extinguishing and flame retardant operation. In use, the first heat-fused component 208, the first elastic component 207, the second heat-fused component 2011, the second elastic component 2010 and the heat dissipation airflow work together to automatically spray out the extinguishing agent when the third circuit board 3 spontaneously combusts, realizing automatic fire extinguishing and flame retardant operation and greatly improving safety performance.

[0043] During the heat dissipation process, since the first chamber 92 and the second chamber 93 are used to store the extinguishing agent, air cannot flow through the hollow plate 202 corresponding to the positions of the first chamber 92 and the second chamber 93, resulting in a reduction in the heat dissipation effect of the corresponding positions of the third circuit board 3. At this time, the heat on the hollow plate 202 corresponding to the positions of the first chamber 92 and the second chamber 93 is conducted to the first elastic member 207 and the second elastic member 2010 through the first connecting block 206 and the second connecting block 209. Then, the heat exchange area is increased by the streamline grooves on the first elastic member 207 and the second elastic member 2010, thereby improving the heat dissipation effect of the third circuit board 3 corresponding to the positions of the first chamber 92 and the second chamber 93.

[0044] Implementation Plan 2

[0045] Based on implementation plan 1, such as Figure 1-3 and Figure 9-11 As shown, the blower assembly includes a connecting cylinder 301, a fan 302, a filter screen 303, a vibration unit, and a linkage unit. The connecting cylinder 301 is screwed onto the lower outer side of the pipe 201 on the left. The fan 302 is fixed to the lower inner side of the connecting cylinder 301. The filter screen 303 is fixed to the lower inner side of the connecting cylinder 301 and is located below the fan 302. The vibration unit is connected to the lower inner side of the connecting cylinder 301 and is located above the filter screen 303. The linkage unit is connected to the lower inner side of the connecting cylinder 301 and is located above the vibration unit.

[0046] The vibration unit includes a third connecting block 304, a round rod 305, a first ring 306, and a spring 307. Four third connecting blocks 304 are welded to the lower inner side of the connecting cylinder 301, and all four third connecting blocks 304 are located above the filter screen 303. A round rod 305 is slidably connected to each of the four third connecting blocks 304. A first ring 306 is welded between the lower ends of the four round rods 305. The first ring 306 is in contact with the filter screen 303. A spring 307 is sleeved on each of the four round rods 305. One end of the spring 307 is welded to the adjacent third connecting block 304, and the other end of the spring 307 is welded to the first ring 306.

[0047] The linkage unit includes a second ring 308, a first linkage block 309, a second linkage block 3010, a third linkage block 3011, a spring telescopic rod 3012, and a fourth linkage block 3013; the lower inner side of the connecting cylinder 301 is damped and rotatably connected to the second ring 308, and the second ring 308 is located above the third connecting block 304; several first linkage blocks 309 are welded in a ring array on the lower side of the second ring 308; a second linkage block 3013 is welded to the inner side of the second ring 308. Block 3010; the third linkage block 3011 is slidably connected to the left side of the second linkage block 3010; the upper front part of the third linkage block 3011 is an inclined surface; an elastic telescopic rod 3012 is fixedly connected to the second linkage block 3010; the telescopic end of the elastic telescopic rod 3012 is fixedly connected to the third linkage block 3011; a fourth linkage block 3013 is welded to the lower side of the rotating part of the fan 302, and the fourth linkage block 3013 cooperates with the third linkage block 3011; the first linkage block 309 is a hemisphere.

[0048] In Implementation Scheme 1, the specific operation of supplying air to the left-side pipe 201 via the blower assembly is as follows: the blower 302 is started. Viewed from above, the blades of the blower 302 rotate clockwise, thereby drawing air upward into the left-side pipe 201. Dust in the air is intercepted by the filter screen 303. During this process, the blades of the blower 302 drive the fourth linkage block 3013 to perform a clockwise circular motion, causing the fourth linkage block 3013 to contact the upper front part of the third linkage block 3011. Since the upper front part of the third linkage block 3011 is inclined, the fourth linkage block 3013 pushes the third linkage block 3011 downward. The third linkage block 3011 compresses the elastic telescopic rod 3012. The fourth linkage block 3013 continues to perform a circular motion, passing the third linkage block 3011. The elastic telescopic rod 3012 rebounds, causing the third linkage block 3011 to move back to its original position.

[0049] When excessive dust accumulates on the lower side of the filter screen 303, it reduces airflow, thus decreasing heat dissipation. At this time, the blades of the fan 302 rotate counter-clockwise, causing the fan 302 to blow air downwards, clearing the dust accumulated on the lower side of the filter screen 303. During this process, the blades of the fan 302 drive the fourth linkage block 3013 to rotate counter-clockwise. The fourth linkage block 3013 rotates counter-clockwise and contacts the third linkage block 3011. The fourth linkage block 3013 continues to rotate counter-clockwise, pushing the third linkage block 3011 to move. This causes the third linkage block 3011 to drive the second linkage block 3010 to rotate. The second linkage block 3010 drives the second ring 308 to rotate. The second ring 308 drives the first linkage block 309 to rotate in a circular motion, contacting the round rod 305. Because the first... The first linkage block 309 is a hemispherical shape, which pushes the round rod 305 downward. The round rod 305 drives the first ring 306 downward and stretches the spring 307. After the first linkage block 309 passes the round rod 305, the spring 307 rebounds and drives the first ring 306 back to its original position, thereby causing the first ring 306 to vibrate. The first ring 306 drives the filter screen 303 to vibrate, so that the filter screen 303 vibrates while being backflushed to remove dust, thereby improving the dust removal efficiency. At the same time, through the cooperation of the third linkage block 3011, the elastic telescopic rod 3012 and the fourth linkage block 3013, the first ring 306 will vibrate the filter screen 303 only during the backflushing dust removal process, avoiding the problem of the filter screen 303 generating an electric charge and attracting dust due to real-time vibration.
