Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a modular radiator. Background Technology

[0002] As the power of stage lighting equipment continues to increase, the heat dissipation capacity of traditional heat sinks is gradually becoming insufficient under high power density.

[0003] Patent document CN219222330U discloses a high thermal conductivity dual-fan column heat sink for stage lights, comprising a phase change heat column, several heat dissipation fins, and a fan bracket fixing plate. One end of the phase change heat column is designated as the heat absorption end, and the interior of the phase change heat column is filled with a phase change medium. The phase change medium absorbs heat and vaporizes through the heat absorption end, and releases heat through the phase change heat column and heat dissipation fins. After releasing heat, the phase change medium liquefies and flows to the heat absorption end. The heat dissipation fins are fitted onto the outer surface of the phase change heat column through through holes, and folded edges are provided on both sides of the heat dissipation fins, forming a semi-enclosed airflow channel with the adjacent heat dissipation fins. The fan bracket fixing plate is respectively disposed at both ends of the phase change heat column, and several connection holes for mounting fan brackets are provided on the fan bracket fixing plate. This utility model improves the heat dissipation efficiency of the heat dissipation fins by providing folded edges on both sides of the heat dissipation fins, which form a semi-enclosed airflow channel with the adjacent heat dissipation fins.

[0004] In the above solution, the heat sink absorbs heat from the heat source through a phase change heat column. However, the absorption end of the phase change heat column protrudes from the fixed plate, which is not conducive to connecting with the heat source and easily affects the heat absorption efficiency and stability of the phase change heat column. The overall height of the heat sink is relatively high, and a fan bracket and fan need to be designed. This does not meet the requirements of the existing compact installation space and the number of heat sources to dissipate heat. At the same time, the existing air duct structure is not suitable for dissipating heat in all directions. Therefore, it is necessary to provide a modular heat sink to solve the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a modular heat sink.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A modular heat sink includes a base plate, a heat column, and a heat sink fin. The top surface of the base plate has a heat sink fixing groove, and the bottom surface of the base plate has a heat column fixing groove. An annular groove is provided between the heat sink fixing groove and the heat column fixing groove. The heat column includes a tube body and a base, which are integrally connected. The tube body passes through the annular groove so that the base abuts against the heat column fixing groove. A cylindrical groove is provided in the middle of the heat sink, which is fitted onto the tube body. The bottom of the heat sink is pressed against the heat sink fixing groove. The base absorbs heat from the lamp and dissipates heat to the surrounding area of ​​the heat sink through the tube body.

[0008] The present invention is further configured such that the base plate has arrayed heat sink fixing holes in the middle, and the heat sinks are symmetrically provided with locking grooves. Bolts pass through the heat sink fixing holes and locking grooves in sequence to fix the heat sinks to the base plate.

[0009] The present invention is further configured such that an adhesive layer is coated on the surface of the heat sink fixing groove, and the adhesive layer is used to enhance the connection strength.

[0013] The present invention is further configured such that the base plate has mounting holes arranged in an array along its edge, and bolts pass through the mounting holes to fix the base plate to the lamp.

[0017] 2. This utility model, by designing a wire hole, facilitates wire routing, avoids the risk of airflow blockage or short circuit caused by wire tangling, and improves safety performance. At the same time, the wire hole design reduces the external space occupied by cables, lowers the height of the heat sink, optimizes the airflow structure of the heat sink, and optimizes space, making the overall structure more compact.

[0018] 3. The top surface of the tube body of this utility model is lower than the top surface of the heat sink.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] Example 1:

[0028] In this embodiment, as Figure 1-6As shown, the present invention proposes a modular heat sink, including a base plate 1, a heat column 2, and a heat sink 3. The top surface of the base plate is symmetrically provided with a heat sink fixing groove 11, and the bottom surface of the base plate is symmetrically provided with a heat column fixing groove 12. An annular groove 13 is provided between the heat sink fixing groove and the heat column fixing groove. The heat column includes a tube body 21 and a base 22, which are integrally connected. The tube body passes through the annular groove so that the base abuts against the heat column fixing groove. A cylindrical groove 31 is provided in the middle of the heat sink, which is sleeved on the tube body. The bottom of the heat sink is pressed against the heat sink fixing groove. The base absorbs heat from the lamp and dissipates heat to the surrounding area of ​​the heat sink through the tube body.

[0029] In this embodiment, the base plate is further configured with heat sink fixing holes 14 arranged in the middle, and the heat sink is symmetrically provided with locking grooves 32. The bolts pass through the heat sink fixing holes and locking grooves in sequence to fix the heat sink to the base plate. When the bolts are fastened, glue can be applied to seal them and enhance the fastening firmness.

[0030] In this embodiment, the surface of the heat sink fixing groove is further coated with an adhesive layer, which is used to strengthen the connection.

[0031] In this example, the connection between the heat sink and the base plate is enhanced by a combination of bolted connections and adhesive layers, preventing detachment due to thermal expansion and contraction. At the same time, the high thermal conductivity adhesive fills the tiny gaps between the heat sink and the base plate, reducing contact thermal resistance and improving heat dissipation efficiency.

[0032] In this embodiment, the tube diameter is set to be the same as the diameter of the annular groove and the cylindrical groove, and the base diameter is the same as the diameter of the hot column fixing groove. The consistency of dimensions ensures seamless connection between the hot column and the base plate, reduces interface thermal resistance, and improves heat conduction efficiency.

[0033] In this example, the bottom of the outer shell is sintered with the base, and the flatness requirements of the bottom surface of the outer shell and the bottom surface of the base are relatively high, which is more conducive to the connection with the heat source and can improve the heat absorption efficiency and stability of the heat column.

[0034] In this embodiment, the heat sink is further configured such that the heat sink is rectangular in shape and has ribs 33 and fins 34. The ribs are at 90 degrees to each other, and the ribs and fins form a multi-layer heat dissipation surface, which increases the contact area with the air and accelerates the heat dissipation to the surroundings.

[0035] In this embodiment, the top surface of the tube is lower than the top surface of the heat sink, and the top of the tube is coated with resin adhesive. The resin adhesive is used to protect the tube and seal the top of the tube to prevent oxidation and corrosion of the top of the tube, ensure the working stability of the phase change medium inside the heat column, and extend its service life.

[0036] In this embodiment, the base plate is further configured with mounting holes 15 arranged on its edge. Bolts pass through the mounting holes to fix the base plate to the lamp. The multiple bolts fix the connection stress between the lamp and the heat sink, preventing it from falling off due to vibration or tilting. The multiple mounting hole positions can be adapted to the fixing structure of different lamps, improving the versatility of the heat sink. The bolt connection can also be used with shock-absorbing pads to reduce the impact of lamp vibration on the heat sink.

[0037] In this embodiment, the base plate is further configured with a wire hole 16 in the middle and a wire hole 17 symmetrically arranged on one side of the base plate. The wire hole 1 and the wire hole 2 facilitate wire routing, avoid wire tangling and malfunctions, avoid the risk of heat dissipation airflow blockage or short circuit caused by wire tangling, and improve safety performance. At the same time, the wire hole design reduces the external space occupied by the cable, and the space optimization makes the overall structure more compact.

[0038] Example 2:

[0039] In this embodiment, based on embodiment 1, the base plate has a total length of 362mm and a total width of 232mm. The base plate is rectangular and has rounded corners with a radius of R3mm. The rounded corners can prevent scratches to operators or equipment and improve the appearance quality of the product. The heat sink fixing slot is 120mm long and wide, and the four corners of the heat sink fixing slot are rounded with a radius of R3mm.
