Description

Technical Field

[0001] This utility model relates to the field of power supply heat dissipation technology, specifically a power supply heat sink structure. Background Technology

[0002] When a power module is running, it generates a large amount of heat. In order to keep the power module operating within a suitable temperature range, a suitable power supply heat sink structure is required. Power supply heat sink structures can utilize heat conduction, convection, and radiation.

[0003] Convection typically involves heat transfer through the flow of a fluid medium (such as air). In power supply modules, convection cooling is primarily achieved through fans and housing ventilation holes. When the internal temperature of the power supply module is high, the cooling fan activates, causing surrounding air to circulate and transferring heat away through convection. Natural convection relies on the natural airflow caused by temperature differences, while forced convection uses external forces such as fans to drive airflow. The power supply heatsink structure is then connected to the power supply. However, when connecting the power supply housing and the heatsink structure, the bolt holes on the heatsink structure are fixed, leading to a mismatch between the power supply housing model and the housing model. This can result in the bolt holes on the heatsink structure not matching, making the entire heatsink structure impossible to install. Utility Model Content

[0004] The purpose of this utility model is to provide a power supply heat sink structure to solve the problem mentioned in the background art. When the power supply casing and the heat sink structure are connected, the bolt holes of the power supply heat sink structure and the power supply casing are not compatible due to the different models of the power supply casing. This results in the bolt holes of the power supply heat sink structure and the power supply casing being unable to be installed.

[0006] Preferably, the first rotating component includes two first built-in grooves formed on the end side of the connecting frame, with one side of each first built-in groove extending through the outer side of the connecting frame.

[0007] Preferably, a column is connected inside the first built-in groove, and a rotating block is sleeved on the column, with the end of the rotating block away from the column extending outside the first built-in groove.

[0008] Preferably, the second rotating component includes a bidirectional telescopic rod disposed on the outside of the connecting frame, and the bidirectional telescopic rod has second built-in grooves on both sides.

[0009] Preferably, a rotating rod is rotatably connected inside the second built-in groove, and the end of the rotating rod extends outside the second built-in groove.

[0010] Preferably, the connecting frame has a rotating groove on one side of the second rotating member for inserting the rotating rod, and a shaft column for supporting the rotation of the rotating rod is connected in the rotating groove.

[0011] Preferably, a cooling fan is provided inside the connecting frame, and a drive source is provided inside the cooling fan.

[0012] Preferably, the heat dissipation housing has heat dissipation holes on its periphery. The heat dissipation holes on the four periphery of the heat dissipation housing are rectangular strips, while the heat dissipation holes on the side of the heat dissipation housing away from the power source are threaded strips.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figure 1-4 As shown, a power supply heat sink structure includes a heat sink housing 1, a first rotating component 2, and a second rotating component 3. The heat sink housing 1 is connected to the power supply. The heat sink housing 1 has a rectangular cavity inside, and the side of the heat sink housing 1 facing the power supply is open. In order to allow the cooling fan 11 to better perform convective heat dissipation on the power supply and increase the direct convection area between the cooling fan 11 and the power supply, a connecting frame 12 is connected to the side of the heat sink housing 1 on the power supply. The connecting frame 12 and the heat sink housing 1 are welded together to facilitate the installation and connection of the heat sink housing 1 and the power supply.

[0025] To avoid misalignment when the threaded groove and the threaded groove on the power supply housing are connected, the first rotating part 2 is movably mounted on one side of the connecting frame 12, and the position of the threaded groove on the first rotating part 2 is adjusted by rotating the first rotating part 2.

[0026] To avoid misalignment when connecting the threaded grooves on the power supply housing and the threaded grooves on the power supply housing, the second rotating member 3 is movably positioned on the side of the connecting frame 12 away from the first rotating member 2. Threaded grooves are provided on both the second rotating member 3 and the first rotating member 2. Pushing the second rotating member 3 and the first rotating member 2 adjusts the spacing between the threaded grooves. When there is a slight deviation in the position of the threaded grooves on the power supply housing, the threaded grooves that need to be installed can be aligned by adjusting the first rotating member 2 and the second rotating member 3, thus expanding the usable range of the heat sink housing 1 and the power supply housing during installation.

[0027] To ensure that the first rotating component 2 can rotate on the connecting frame 12, two first built-in grooves 21 are opened on the end side of the connecting frame 12. The first built-in grooves 21 and the connecting frame 12 are integrally molded. One side of the first built-in groove 21 is opened through the outside of the connecting frame 12. The symmetrical design of the first built-in grooves 21 makes the thread groove spacing on one side of the connecting frame 12 adjustable.

[0028] To further ensure the overall rotation of the first rotating component 2, a column 23 is welded and connected in the first built-in groove 21. The column 23 is cylindrical, and a rotating block 22 is sleeved on the column 23. The rotating block 22 has a circular slot for the column 23 to be sleeved. In use, the rotating block 22 is sleeved with the column 23 through its own slot, which facilitates the rotation of the rotating block 22 on the column 23. The end of the rotating block 22 away from the column 23 extends out of the first built-in groove 21, and a threaded groove is provided on the rotating block 22 extending out of the first built-in groove 21.

[0029] To ensure that the threaded groove at the position of the second rotating component 3 can be properly adjusted, a bidirectional telescopic rod 31 is provided on the outside of the connecting frame 12. The bidirectional telescopic rod 31 has second internal grooves 33 on both sides, wherein the second internal grooves 33 are as follows: Figure 2 The bidirectional telescopic rod 31 is shown.

[0030] In order to ensure that the threaded groove on the surface of the bidirectional telescopic rod 31 can be adjusted appropriately, a rotating rod 34 is rotatably connected in the second built-in groove 33 via a rotating shaft. The end of the rotating rod 34 extends outside the second built-in groove 33, and the two sides of the second built-in groove 33 will rotate around the axis of the rotating shaft of the second built-in groove 33.

[0031] The connecting frame 12 has a rotating groove on one side of the second rotating member 3 for the rotating rod 34 to be inserted. The rotating groove is connected to a shaft column for supporting the rotation of the rotating rod 34, which facilitates the rotational connection between the bidirectional telescopic rod 31 and the connecting frame 12.

[0032] The effect achieved by the entire embodiment is that, during use, the heat sink 1 has a rectangular cavity inside, and the side of the heat sink 1 facing the power supply is open. In order for the cooling fan 11 to better perform convective heat dissipation on the power supply, the area of ​​direct convection between the cooling fan 11 and the power supply is increased. During installation, if there is a slight deviation in the position of the threaded groove on the power supply housing, the threaded groove to be installed can be aligned by adjusting the first rotating part 2 and the second rotating part 3, thereby expanding the range of use of the heat sink 1 and the power supply housing during installation.

[0033] Example 2

[0034] like Figure 1-4 As shown, a power supply heat sink structure is provided, in which a cooling fan 11 is provided in the connecting frame 12, and a drive source is provided in the cooling fan 11, wherein the drive source is a motor. When in use, the output end of the motor is connected to the end of the cooling fan 11. After the external power supply is connected, the motor drive source drives the cooling fan 11 to rotate, thereby cooling the power supply on one side of the heat sink housing 1.

[0035] The heat sink housing 1 has heat dissipation holes 13 on its periphery. The heat dissipation holes 13 on the four periphery of the heat sink housing 1 are rectangular strips, while the heat dissipation holes 13 on the side of the heat sink housing 1 away from the power supply are threaded strips. The heat dissipation holes 13 are designed as follows: Figure 3 The surface shown in Figure 5 is used for heat dissipation and ventilation to prevent heat accumulation caused by the cooling fan 11.

[0036] The effect achieved by the entire second embodiment is that, during use, the output end of the motor is connected to the end of the cooling fan 11. After an external power supply is connected, the motor drive source drives the cooling fan 11 to rotate, thereby dissipating heat from the power supply on one side of the heat sink housing 1. Simultaneously, the heat dissipation holes 13 are designed in a manner similar to... Figure 3 The surface shown in Figure 5 is used for heat dissipation and ventilation to prevent heat accumulation caused by the cooling fan 11.

[0037] Working principle: When using this power supply heat sink structure with an external power supply, the heat sink housing 1 has a rectangular cavity inside, and the side of the heat sink housing 1 facing the power supply is open. In order to allow the cooling fan 11 to better perform convection heat dissipation on the power supply, the area of ​​direct convection between the cooling fan 11 and the power supply is increased. When there is a slight deviation in the position of the threaded groove on the power supply housing during installation, the threaded groove to be installed can be aligned by adjusting the first rotating part 2 and the second rotating part 3, thereby expanding the usable range of the heat sink housing 1 and the power supply housing during installation.

[0038] Secondly, during use, the output end of the motor is connected to the end of the cooling fan 11. After connecting to an external power source, the motor drive source drives the cooling fan 11 to rotate, thus cooling the power supply on one side of the heat sink housing 1. Simultaneously, the heat dissipation holes 13 are designed in... Figure 3 The surface shown in Figure 5 is used for heat dissipation and ventilation to prevent heat accumulation during the cooling fan 11, thus completing the work of the power supply heat sink structure.
