Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and in particular to a heat dissipation structure for control machines. Background Technology

[0002] The control unit is a core component of modern electronic devices, responsible for controlling various functional modules. As the performance of electronic devices continues to improve, the power consumption and heat generation of the control unit are also increasing, posing greater challenges to its heat dissipation. If the heat generated by the control unit cannot be dissipated in time, the internal temperature will rise, affecting its performance and stability, and in severe cases, even causing safety hazards. Most existing heat dissipation methods involve designing ventilation holes on the casing to remove heat generated by heat-generating components located on the inner wall of the heat sink. For heat-generating components in the middle of the casing, either air cooling or water cooling is used. Air cooling generates significant noise, and the combination of the fan and ventilation holes leads to a large accumulation of dust inside the casing. Water cooling is more expensive and relatively complex to install and maintain. Furthermore, the water cooling pipes must be sealed to prevent leaks that could cause short circuits on the motherboard. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned problems of the prior art and provide a heat dissipation structure for control machines that balances cost and efficiency, and has the advantages of reliable operation, safety and stability.

[0004] The objective of this utility model is mainly achieved through the following technical solutions:

[0005] A heat dissipation structure for a control machine includes a heat dissipation shell, a through-hole extending through its front and rear ends in the middle of the heat dissipation shell, and a number of first heat dissipation fins located in the through-hole area on the outer surface of the heat dissipation shell.

[0006] The heat dissipation shell is connected to a mounting bracket that surrounds the opening. The mounting bracket is provided with a first heat dissipation protrusion, and a first thermal pad is installed at the end of the first heat dissipation protrusion.

[0007] Furthermore, the first heat dissipation fins are provided at both the upper and lower ends of the opening.

[0008] Furthermore, several of the first heat dissipation fins are arranged in a left-right direction at the opening.

[0009] Furthermore, a second heat dissipation protrusion is provided on the inner wall of the top of the heat dissipation shell, and a second heat-conducting pad is installed at the end of the second heat dissipation protrusion.

[0010] Furthermore, a plurality of second heat dissipation fins are provided on the outer surface of the top of the heat dissipation housing.

[0011] Furthermore, several second heat dissipation fins are arranged in a left-right direction on the heat dissipation shell.

[0012] Furthermore, a third thermal pad is provided on the inner wall of the bottom end of the heat dissipation housing.

[0013] Furthermore, the mounting bracket divides the interior of the heat dissipation housing into an upper mounting area located above the opening and a lower mounting area located below the opening.

[0014] Furthermore, the heat dissipation housing includes a frame, a top plate at the top of the closed frame, and a bottom plate at the bottom of the closed frame.

[0015] Furthermore, the heat dissipation shell, the first heat dissipation boss, the first heat dissipation fin, the second heat dissipation boss, and the second heat dissipation fin are all made of aluminum alloy; the first thermal pad and the second thermal pad are made of silicone.

[0016] This invention offers the following advantages: By incorporating a first thermally conductive pad, a first heat dissipation protrusion, and first heat dissipation fins, the heat generated by the heating element located in the central region of the heat dissipation shell can be rapidly transferred to the opening. The heat is then released and dissipated into the air through air convection at the opening. Similarly, by incorporating a second thermally conductive pad, a second heat dissipation protrusion, a second heat dissipation fin, and a third thermally conductive pad, the heat generated by the heating element located on the inner wall of the heat dissipation shell can be rapidly transferred to the outer surface of the heat dissipation shell. The heat is then released and dissipated through airflow outside the heat dissipation shell. Therefore, this invention ensures efficient heat dissipation of the heating element in the control unit while eliminating exposed through-holes and energy-consuming components, and provides more reliable, safe, and stable heat dissipation. Furthermore, this invention is extremely low in cost and is relatively easy to install and maintain. Attached Figure Description

[0026] Example 1

[0027] like Figures 1 to 9 As shown, the heat dissipation structure for the control machine includes a heat dissipation shell 1, a through-hole 2 extending through both the front and rear ends of the heat dissipation shell 1 in the middle, and a plurality of first heat dissipation fins 3 located in the area of ​​the through-hole 2 on the outer surface of the heat dissipation shell 1.

[0028] The heat dissipation shell 1 is connected to a mounting bracket 4 that surrounds the opening 2. The mounting bracket 4 is provided with a first heat dissipation protrusion 5, and a first thermal pad 6 is installed at the end of the first heat dissipation protrusion 5.

[0029] In this embodiment, the heat dissipation housing 1 is as follows: Figure 5As shown, the mounting bracket 4 divides the interior of the heat dissipation housing 1 into an upper mounting area 14 located above the opening 2 and a lower mounting area 15 located below the opening 2. The PCB board can be installed in the upper mounting area 14, and the first thermal pad 6 can be directly facing the heat-generating chip on the bottom of the PCB board. In this way, the heat generated by the heat-generating chip will be transferred to the opening 2 through the first thermal pad 6, the first heat dissipation protrusion 5, and the mounting bracket 4. Then, through the air convection of the opening 2 and the arrangement of the first heat dissipation fins 3, the heat will be released and evaporated into the air.

[0030] Among them, several of the first heat dissipation fins 3 are arranged in a left-right direction at the opening 2, which makes it easier for airflow to carry away the heat on the first heat dissipation fins 3.

[0031] like Figure 5 As shown, to balance structural stability and efficient heat dissipation, the heat dissipation shell 1 is provided with two parallel openings 2.

[0032] Preferably, the first heat dissipation fins 3 are provided at both the upper and lower ends of the opening 2.

[0033] In this implementation, such as Figure 5 As shown, a power supply 18 is installed in the lower mounting area 15. The heat generated by the power supply can also be transferred to the opening 2 through the mounting bracket 4. Then, through the air convection of the opening 2 and the action of the first heat dissipation fin 3 located at the lower end of the opening 2, the aforementioned heat is released into the air.

[0034] Preferably, a second heat dissipation protrusion 7 is provided on the inner wall of the top of the heat dissipation shell 1, and a second heat conduction pad 8 is installed at the end of the second heat dissipation protrusion 7.

The heat generated by the heat-generating chip on the bottom PCB board is transferred by the first thermal pad 6, the first heat dissipation protrusion 5, the mounting bracket 4, the through 2, and the first heat dissipation fin 3. The heat generated by the heat-generating chip on the top PCB board is transferred to the top of the heat dissipation shell 1 by the second thermal pad 8 and the second heat dissipation protrusion 7, and the heat is released and evaporated by the air flow outside the top of the heat dissipation shell 1.

[0036] Preferably, the outer surface of the top end of the heat dissipation housing 1 is provided with a plurality of second heat dissipation fins 9. The arrangement of the second heat dissipation fins 9 can accelerate the efficiency of heat dissipation into the air.

[0037] Preferably, a plurality of the second heat dissipation fins 9 are arranged in a left-right direction on the heat dissipation housing 1.

[0038] In this embodiment, airflow is more conducive to carrying away the heat from the second heat dissipation fin 9.

[0039] Preferably, a third thermal pad 10 is provided on the inner wall of the bottom end of the heat dissipation housing 1.

[0040] In this embodiment, the third thermal pad 10 can quickly transfer the heat generated at the bottom of the power supply in the lower mounting area 15 to the bottom of the heat dissipation shell 1, and release and evaporate the aforementioned heat by utilizing the air flow outside the bottom of the heat dissipation shell 1.

[0041] For structural optimization, preferably, the heat dissipation shell 1 includes a frame 11, a top plate 12 at the top of the closed frame 11, and a bottom plate 13 at the bottom of the closed frame 11.

[0042] In this embodiment, the second heat dissipation boss 7 and the second heat dissipation fin 9 can be disposed on the top plate 12; the third heat conduction pad 10 can be disposed on the bottom plate 13.

[0043] Preferably, the heat dissipation shell 1, the first heat dissipation boss 5, the first heat dissipation fin 3, the second heat dissipation boss 7 and the second heat dissipation fin 9 are all made of aluminum alloy; the first thermal pad 6 and the second thermal pad 8 are made of silicone.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
