Description

Technical Field

[0001] This utility model relates to the field of power insulation spraying application technology, and in particular to a multi-layer stacked aluminum profile heat sink with a wave-shaped flow guide groove. Background Technology

[0002] In the fields of electronic equipment and machinery, heat sinks are important components. Their function is to dissipate the heat generated during equipment operation in a timely manner to ensure the normal operation of the equipment. Currently, commonly used heat sinks include aluminum profile heat sinks and copper heat sinks, among which aluminum profile heat sinks are widely used due to their advantages such as light weight, low cost, and good heat dissipation performance.

[0003] However, traditional aluminum profile radiators are mostly single-layer structures with limited heat dissipation area and low heat dissipation efficiency. To improve heat dissipation efficiency, some multi-layer stacked aluminum profile radiators have emerged, but the airflow channels of these radiators are mostly straight, resulting in a short airflow path and short contact time with the radiator, leading to less than ideal heat dissipation. In addition, the connection structure of existing multi-layer stacked aluminum profile radiators is relatively complex and inconvenient to install. Therefore, this utility model proposes a multi-layer stacked aluminum profile radiator with a corrugated guide groove. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multi-layer stacked aluminum profile radiator with a wave-shaped flow guide groove, so as to increase the heat dissipation area, extend the flow path of airflow in the radiator, improve the heat dissipation efficiency, and at the same time simplify the connection structure and facilitate installation.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a multi-layer stacked aluminum profile heat sink with a wave-shaped flow guide groove is provided, including a connecting base plate, wherein heat dissipation units are symmetrically engaged on both sides of the connecting base plate to achieve heat dissipation on both sides of the connecting base plate. The two heat dissipation units are stacked on a connecting substrate. The two heat dissipation units are attached to both sides of the connecting substrate by their internal wavy heat sinks to form a serpentine airflow channel to enhance the heat dissipation area.

[0006] The present invention is further configured such that: the two sides of the connecting substrate are symmetrically fixedly connected with side edges, and the cross-section of each side edge is trapezoidal, and the end face of the side edge is fixedly connected with a stop block.

[0007] The above technical solution facilitates the use of the stop block on the side to lock and fix the heat dissipation unit, making installation and replacement convenient.

[0008] The present invention is further configured such that mounting holes are provided on both sides near the corners.

[0009] The above technical solution facilitates the pre-installation and fixation of the connecting substrate using mounting holes, thereby making it easier to press and fix the heat dissipation unit later.

[0010] The present invention is further configured such that: the heat dissipation unit includes a heat dissipation plate, the heat dissipation plate has multiple ventilation slots inside, multiple heat dissipation fins are fixedly connected to both sides of the heat dissipation plate, and a retaining edge is symmetrically fixedly connected to one side of the heat dissipation plate near the edge, and the retaining edge is snapped into place by a stop block.

[0011] The above technical solution facilitates the use of the snap-fit ​​edge on the heat sink to press and snap onto the connecting substrate, and the use of multiple wavy heat sinks can increase the heat dissipation area of ​​the entire heat dissipation unit, thereby enhancing the heat dissipation effect.

[0012] The present invention is further configured such that the plurality of ventilation slots are arranged at equal intervals along the width direction of the heat sink.

[0013] The above technical solution facilitates rapid ventilation and heat dissipation by using ventilation slots in conjunction with heat sinks, thereby improving the removal of internal heat.

[0014] The present invention is further configured such that: all of the heat sinks are wavy in shape, and thermally conductive adhesive is provided at the connection between the heat sinks and the connecting substrate.

[0015] The above technical solution utilizes a wave-shaped heat sink to create a serpentine heat dissipation channel, thereby increasing the heat dissipation area and improving overall heat dissipation efficiency.

[0016] The present invention is further configured such that: the side wall of the card edge is arc-shaped and the connection with the heat sink is arc-shaped; the bottom of the card edge is an opening with an arc-shaped bend; and the stop block is inserted into the inside of the card edge from the opening.

[0017] The above technical solution facilitates the connection of the heat sink and the connecting substrate by using the side to drive the stop block to be inserted into the elastically set clamp edge, thereby using the clamp edge to limit and fix it, so as to realize the heat sink unit is firmly installed on the connecting substrate.

[0018] The beneficial effects of this utility model are as follows: 1. The multi-layer stacked aluminum profile radiator with wave-shaped flow guide groove proposed in this utility model increases the heat dissipation area of ​​the radiator by setting up multi-layer stacked aluminum profile heat dissipation units, which is conducive to improving heat dissipation efficiency. 2. The multi-layer stacked aluminum profile heat sink with wavy guide grooves proposed in this utility model has wavy guide grooves on both the upper and lower surfaces of the aluminum profile heat sink unit, forming a serpentine airflow channel between adjacent heat sinks, which prolongs the flow path of the airflow in the heat sink, increases the contact time between the airflow and the heat sink, and further improves the heat dissipation efficiency. 3. The multi-layer stacked aluminum profile heat sink with wavy guide groove proposed in this utility model has a connecting base plate between the stacked heat dissipation units, which allows for pre-installation and fixation in a narrow space, thereby facilitating the installation and subsequent replacement and maintenance of the heat dissipation units.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figures 1-3 As shown, a multi-layer stacked aluminum profile heat sink with a wave-shaped flow guide groove includes a connecting base plate 1. Side edges 11 are symmetrically fixedly connected to both sides of the connecting base plate 1, and the cross-section of each side edge 11 is trapezoidal. A stop block 13 is fixedly connected to the end face of each side edge 11, which facilitates the use of the stop block 13 on the side edge 11 to engage and fix the heat dissipation unit 2, making it convenient for installation and replacement. Mounting holes 12 are provided near the corners of both sides 11, which facilitates the pre-installation and fixation of the connecting base plate 1 using the mounting holes 12, thereby facilitating the subsequent pressing and fixing of the heat dissipation unit 2.

[0023] like Figure 4 As shown, heat dissipation units 2 are symmetrically engaged on both sides of the connecting substrate 1 to achieve heat dissipation on both sides of the connecting substrate 1. The two heat dissipation units 2 are stacked on the connecting substrate 1. The two heat dissipation units 2 are respectively attached to both sides of the connecting substrate 1 by the corrugated heat dissipation fins 23 inside them to form a serpentine airflow channel to enhance the heat dissipation area. The heat dissipation unit 2 includes a heat dissipation plate 21. The heat dissipation plate 21 has multiple ventilation slots 22 inside. The multiple ventilation slots 22 are arranged at equal intervals along the width direction of the heat dissipation plate 21 to facilitate rapid ventilation and heat dissipation by using the ventilation slots 22 in conjunction with the heat dissipation fins 23 to improve the discharge of internal heat. Multiple heat dissipation fins 23 are fixedly connected to both sides of the heat dissipation plate 21. The multiple heat dissipation fins 23 are all corrugated, and thermally conductive adhesive is provided at the connection between the multiple heat dissipation fins 23 and the connecting substrate 1. The corrugated heat dissipation fins 23 can form a serpentine heat dissipation channel, thereby increasing the heat dissipation area and improving the overall heat dissipation efficiency.

[0024] like Figure 2 and Figure 5 As shown, a retaining edge 24 is symmetrically fixedly connected to one side of the heat sink 21 near the edge, and the retaining edge 24 is engaged with the stop block 13, so that the retaining edge 24 on the heat sink 21 can be used to press and engage it with the connecting base plate 1. The use of multiple wavy heat sinks 23 can increase the heat dissipation area of ​​the entire heat dissipation unit 2, thereby enhancing the heat dissipation effect. The side wall of the retaining edge 24 is arc-shaped and is arc-shaped when connected with the heat sink 21. The bottom of the retaining edge 24 is set as an opening, and the opening is arc-shaped. The stop block 13 is inserted into the inside of the retaining edge 24 from the opening, so that when the heat sink 21 and the connecting base plate 1 are connected, the side 11 can drive the stop block 13 to be inserted into the elastic retaining edge 24, thereby using the retaining edge 24 to limit and fix it, so that the heat dissipation unit 2 is firmly installed on the connecting base plate 1.

[0025] In use, the connecting base plate 1 is first fixed in the corresponding installation position through its mounting hole 12. Then, the heat dissipation unit 2 is pressed against the stop block 13 through the clamping edge 24 on both sides. At this time, the stop block 13 is inserted into the inside from the opening of the clamping edge 24 and squeezes the opening of the clamping edge 24 to deform it. When the stop block 13 enters the inside of the clamping edge 24, the clamping edge 24 is connected to the stop block 13 by elastic reset, thereby realizing the quick installation and fixation. The multiple wavy heat dissipation fins 23 on the heat dissipation plate 21 can make the heat dissipation channel form a serpentine heat dissipation channel, thereby increasing the heat dissipation area and improving the overall heat dissipation efficiency.
