Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a modular composite heat dissipation electronic device protective shell. Background Technology

[0002] As a crucial guarantee for the safe operation of electronic devices, protective enclosures typically need to balance physical protection and heat dissipation. Their structure generally includes an outer shell to support the device and a cover plate that fits over the shell. To meet heat dissipation requirements, existing covers often incorporate one-piece molded heat dissipation fins as a primary heat dissipation structure, achieving passive heat dissipation by increasing the heat dissipation area. This design is widely used in low-to-medium power devices.

[0003] When the power of the device increases, resulting in increased heat generation, the original heat dissipation fins alone are insufficient to meet the heat dissipation requirements, and an additional cooling fan is needed to assist in heat dissipation.

[0004] However, some existing covers do not have a pre-installed fan mounting structure, so fans cannot be directly added to the existing covers. Instead, the entire cover must be replaced with a dedicated cover that integrates a fan. This results in higher production costs and more work for the dedicated cover. Conversely, when the power of the equipment drops to a low to medium level, the cover with the fan still needs to run the fan continuously, causing unnecessary power waste. As a result, the heat dissipation structure of these existing covers is too simple and cannot dynamically adapt to the heat dissipation capacity according to the power of the equipment. They have poor versatility and it is difficult to flexibly adjust the heat dissipation mode according to the actual power requirements. Utility Model Content

[0005] In view of this, the present invention provides a modular composite heat dissipation electronic device protective housing. By setting a detachable heat dissipation unit on the cover plate, the heat dissipation unit is independent of the original heat dissipation fins. The heat dissipation unit can be flexibly added or removed according to the power requirements of the device without replacing the cover plate. It retains the basic heat dissipation function of the original heat dissipation fins and can adapt to the heat dissipation requirements of devices with different power, realizing flexible expansion of heat dissipation capacity, avoiding the cost and resource waste of replacing the cover plate, and improving the versatility of the housing.

[0006] To address the aforementioned technical problems, this utility model provides a modular composite heat dissipation protective housing for electronic devices. The modular composite heat dissipation protective housing includes a shell for housing the electronic device and a cover plate. The cover plate has a heat dissipation tooth body, and the heat dissipation tooth body and the cover plate are integrally molded. The heat dissipation tooth body covers the upper surface of the cover plate, forming the cover plate's intrinsic heat dissipation structure to achieve passive heat dissipation. The cover plate also has a mounting platform, which is an independent flat area on the cover plate surface. A heat dissipation unit is detachably installed within the mounting platform. This heat dissipation unit is independent of the heat dissipation teeth; the heat dissipation unit and the heat dissipation teeth do not affect each other and do not overlap with the heat dissipation tooth body. When the electronic device inside the shell... When the heat output of the sub-device is low, a heat dissipation unit does not need to be installed on the mounting platform; effective heat dissipation can be achieved solely through the heat dissipation fins. When the electronic device generates significant heat, a heat dissipation unit can be added to the mounting platform. The heat dissipation unit can be a cooling fan, a semiconductor cooling chip, or other device structure capable of actively dissipating heat. By selectively installing a heat dissipation unit on the mounting platform without affecting the cover plate and the heat dissipation fins, the overall flexibility and versatility of the cover plate can be effectively improved. This not only retains the original heat dissipation function of the heat dissipation fins but also adapts to the heat dissipation needs of devices with different power outputs, avoiding the cost and resource waste of replacing the cover plate and improving the versatility of the casing.

[0007] The heat dissipation unit specifically uses a cooling fan, which is detachably mounted on the mounting platform. When it is necessary to improve the heat dissipation function, the cooling fan is installed on the mounting platform. The forced convection of the cooling fan removes the heat generated by the mounting platform and even the electronic equipment, which works in conjunction with the passive heat dissipation of the heat dissipation fins. When the heat generation is normal and no additional heat dissipation is needed, the cooling fan can be removed from the mounting platform to avoid unnecessary waste of resources.

[0008] The base of the cooling fan has four through holes on its surface, located at the four corners of the base. The mounting platform also has four threaded holes. When the base is attached to the mounting area, each through hole and threaded hole is coaxially aligned. At this time, bolts can be passed through the through holes and screwed into the threaded holes in sequence, so that the bolts and threaded holes achieve thread engagement, thereby fixing the cooling fan.

[0009] The cooling fan is equipped with a protective plate, which is located above the cooling fan and covers it. The upper surfaces of the protective plate and the cooling fins are on the same horizontal plane. The surface of the protective plate has ventilation slots, through which the cooling fan exhausts the air carrying heat. The design of the protective plate also prevents debris from falling into the cooling fan and causing damage.

[0010] The protective plate can be detachably installed on the cooling fan using magnetic, bolt, or snap-on design. With the detachable protective plate, when the protective plate is dusty or damaged, it can be removed and cleaned or replaced separately without removing the entire fan.

[0011] The installation platform has four extension blocks protruding upwards at its four corners, with threaded holes on the top surface of each extension block. The protective plate has positioning holes at its corners that are coaxial with the threaded holes. After the cooling fan is installed, the protective plate is placed against the top surface of the extension blocks. At this time, the bottom of the protective plate contacts the top surface of the extension blocks, while the protective plate does not contact the cooling fan. The threaded holes and positioning holes are coaxial. The bolts are then passed through the positioning holes and screwed into the threaded holes to fix the protective plate.

[0012] The extension block and the heat dissipation fins are integrally molded into an inseparable whole structure, ensuring that the structural strength of the extension block is consistent with that of the cover plate, improving the load-bearing capacity of the extension block and preventing breakage.

[0013] In addition to cooling fans, the mounting platform can also accommodate other heat dissipation units, including heat dissipation bosses. When the product's transmission power is no more than 1W, the mounting platform can be fitted with heat dissipation bosses. The bottom surface of the heat dissipation boss abuts tightly against the surface of the mounting platform, and a ventilation slot extends vertically from the top to the bottom surface of the heat dissipation boss and through to the surface of the mounting platform. Once the heat dissipation boss is installed, its outer surface, together with the inner wall of the ventilation slot, forms a large heat dissipation area, constituting a composite structure similar to heat dissipation teeth. The heat dissipation boss and the inner wall of the ventilation slot achieve passive heat dissipation through their contact with the outside air. Furthermore, the ventilation slot, as a through airflow channel, guides airflow to expel heat from the mounting platform area, forming synergistic convection with the heat dissipation teeth on the cover plate, improving overall heat dissipation efficiency. This design allows the mounting platform to flexibly adapt to different heat dissipation solutions according to the equipment power, avoiding structural redundancy in low-power scenarios and enhancing heat dissipation capabilities in the low-to-medium power range while maintaining protection through the heat dissipation tooth-like structure of the heat dissipation boss.

[0014] A fixing plate is provided on the upper part of the heat dissipation boss. The surface of the fixing plate has a hole that is coaxial with the threaded hole on the surface of the extension block. When the heat dissipation boss abuts against the surface of the mounting platform, the lower surface of the fixing plate can abut against the upper end face of the extension block. The hole of the fixing plate is coaxial with the threaded hole of the extension block. At this time, the heat dissipation boss can be fixed by passing a bolt through the hole and threading it into the threaded hole.

[0015] The fixing plate is located on the upper surface of the heat dissipation boss, and the ventilation slot extends from the top surface of the fixing plate to the bottom surface of the heat dissipation boss. When the heat dissipation boss and the mounting platform abut against each other, the ventilation slot and the surface of the mounting platform form an airflow channel to ensure the overall heat dissipation efficiency.

[0016] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0017] 1. When using this utility model, a detachable heat dissipation unit is set on the cover plate. This heat dissipation unit is independent of the original heat dissipation teeth. The heat dissipation unit can be flexibly added or removed according to the power requirements of the equipment without replacing the cover plate. It retains the basic heat dissipation function of the original heat dissipation teeth and can adapt to the heat dissipation requirements of different power equipment, realizing flexible expansion of heat dissipation capacity, avoiding the cost and resource waste of replacing the cover plate, and improving the versatility of the shell.

[0018] 2. When this utility model is used, the heat dissipation unit and the heat dissipation tooth body are independently arranged and do not interfere with each other. The passive heat dissipation of the original heat dissipation tooth and the active heat dissipation (or auxiliary heat dissipation) of the heat dissipation unit work together to meet the basic heat dissipation needs of low-power equipment and cope with the enhanced heat dissipation needs of high-power equipment, thus achieving a composite heat dissipation effect.

[0019] 3. When this utility model is used, the design of the protective plate and the heat dissipation protrusion takes into account both heat dissipation and protection functions: the protective plate can block debris and protect the cooling fan, and the heat dissipation protrusion assists in heat dissipation in low-power scenarios through a heat dissipation tooth-like structure, which solves the problem of incompatibility between heat dissipation and protection in traditional structures.

[0020] 4. When this utility model is used, the extension block, cover plate, and heat dissipation tooth body are integrally formed, and the heat dissipation fan, protective plate, and heat dissipation boss share the same installation point, which simplifies the structural design and reduces production and assembly costs; at the same time, the detachable structure facilitates later maintenance and component replacement, reducing resource waste.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0029] Example 1:

[0030] A modular composite heat dissipation electronic device protective housing, such as Figure 1-3 As shown: It includes a housing 100 for accommodating electronic devices, and a cover plate 200 that is detachably connected to the top of the housing 100. The cover plate 200 is provided with a heat dissipation tooth body 201. The heat dissipation tooth body 201 and the cover plate 200 are integrally molded. The heat dissipation tooth body 201 covers the upper surface of the cover plate 200. The heat dissipation tooth body 201 forms the original heat dissipation structure of the cover plate 200. By increasing the contact area with the air, passive heat dissipation is achieved by heat conduction and natural convection.

[0031] The cover plate 200 is also provided with a mounting platform 300. The mounting platform 300 is an independent flat area on the surface of the cover plate 200, and the mounting platform 300 and the heat dissipation tooth body 201 are located on the same plane on the cover plate 200. Therefore, the part of the cover plate 200 that does not overlap with the mounting platform 300 is the heat dissipation tooth body 201. A heat dissipation unit is detachably installed inside the mounting platform 300. This heat dissipation unit is independent of the heat dissipation tooth, and the heat dissipation unit and the heat dissipation tooth do not affect each other and do not overlap with the heat dissipation tooth body 201. When the heat dissipation power of the electronic device inside the housing 100 is low, the heat dissipation unit does not need to be installed inside the mounting platform 300, and only the heat dissipation tooth body 201 is needed. To achieve effective heat dissipation, when electronic devices overheat, a heat dissipation unit can be installed on the mounting platform 300. The heat dissipation unit can be a cooling fan 400, a semiconductor cooling chip, or other device structure that can actively dissipate heat. By selectively installing the heat dissipation unit on the mounting platform 300 without affecting the cover plate 200 and the heat dissipation tooth body 201, the overall flexibility and versatility of the cover plate 200 can be effectively improved. It not only retains the original heat dissipation function of the heat dissipation tooth body 201, but also adapts to the heat dissipation needs of devices with different power, avoiding the cost and resource waste of replacing the cover plate 200 and improving the versatility of the casing.

[0032] Specifically, the heat dissipation unit uses a cooling fan 400, which is detachably mounted on the mounting platform 300. When enhanced heat dissipation is required, the cooling fan 400 is installed on the mounting platform 300. When the cooling fan 400 is working, it accelerates airflow. As the heat from the electronic device is conducted to the cover plate 200 and the mounting platform 300, the forced convection of the cooling fan 400 removes the heat from the mounting platform 300 and even the electronic device, thus working in conjunction with the passive heat dissipation of the heat sink body 201. When the heat generation is normal and no additional heat dissipation is needed, the cooling fan 400 can be removed from the mounting platform 300, avoiding unnecessary waste of resources.

[0033] It is worth mentioning that the mounting platform 300 is a rectangular area of ​​50*50mm. When the electronic device is installed inside the housing 100 and sealed by the cover plate 200, the mounting platform 300 is located directly above the heat source of the electronic device. Since the heat source of the electronic device is higher and more concentrated, the heat dissipation unit at the mounting platform 300 can dissipate heat better.

[0034] Furthermore, the base surface of the cooling fan 400 has four through holes 401, which are located at the four corners of the base. The mounting platform 300 also has four threaded holes.

[0035] When the base is attached to the installation area, each through hole 401 is coaxially aligned with the threaded hole. At this time, bolts can be passed through the through holes 401 in sequence and screwed into the threaded holes to achieve thread engagement between the bolts and the threaded holes, thereby fixing the cooling fan 400.

[0036] It is worth mentioning that the mounting platform 300 is equipped with a power interface, while the power supply body is located inside the housing 100. When the cooling fan 400 is attached to the mounting platform 300, the cooling fan 400 works with the power interface to supply power.

[0037] according to Figure 2 and Figure 3 As shown, a protective plate 500 is provided on the cooling fan 400. The protective plate 500 is located above the cooling fan 400, covering the cooling fan 400. The upper surfaces of the protective plate 500 and the cooling fins are on the same horizontal plane. A ventilation groove 501 is provided on the surface of the protective plate 500. The cooling fan 400 exhausts the air carrying heat through the ventilation groove 501. Through the design of the protective plate 500, debris is blocked and prevented from falling into the cooling fan 400, thus avoiding damage to the cooling fan 400.

[0038] Specifically, the protective plate 500 can be detachably installed on the cooling fan 400 through magnetic, bolt or snap-on design. With the detachable protective plate 500, when the protective plate 500 is dusty or damaged, it can be removed and cleaned or replaced separately without removing the entire fan.

[0039] Specifically, four extension blocks 301 are provided at the four corners inside the installation platform 300, and threaded holes are opened on the top surface of the extension blocks 301.

[0040] The protective plate 500 has a positioning hole 502 at its corner that is coaxial with the threaded hole;

[0041] After the cooling fan 400 is installed, the protective plate 500 is placed against the top surface of the extension block 301. At this time, the bottom of the protective plate 500 contacts the top surface of the extension block 301, while the protective plate 500 does not contact the cooling fan 400. The threaded hole and the positioning hole 502 are in the same axial position. Then, the bolt is passed through the positioning hole 502 and screwed into the threaded hole to fix the protective plate 500.

[0042] Furthermore, the extension block 301, the heat dissipation tooth body 201, and the cover plate 200 are integrally formed through the same process (such as die casting or cutting). The three are an inseparable whole structure, ensuring that the structural strength of the extension block 301 is consistent with that of the cover plate 200, improving the load-bearing capacity of the extension block 301, and preventing breakage.

[0043] Example 2:

[0044] The difference from Embodiment 1 is that when the heat dissipation unit is specifically used as a heat dissipation boss 600 with ventilation slots 601, passive heat dissipation is achieved through the heat dissipation boss 600 and ventilation slots 601, and heat dissipation is achieved in conjunction with the heat dissipation tooth body 201.

[0045] like Figure 4 and Figure 5 As shown, in addition to the cooling fan 400, other heat dissipation units can also be installed on the mounting platform 300, including heat dissipation bosses 600.

[0046] When the transmission power of the electronic device inside the housing 100 is no greater than 0.5W, the mounting platform 300 can be left empty, and no structure needs to be installed on the mounting platform 300;

[0047] When the product’s transmission power is greater than 1W and not greater than 2W, the cooling fan 400 can be installed on the mounting platform 300.

[0048] When the product's transmission power is no greater than 1W, the mounting platform 300 can be fitted with a heat dissipation boss 600. The bottom surface of the heat dissipation boss 600 is in close contact with the surface of the mounting platform 300, and a ventilation slot 601 is vertically oriented through it. This ventilation slot 601 extends from the top surface of the heat dissipation boss 600 to the bottom surface and penetrates the surface of the mounting platform 300. After the heat dissipation boss 600 is installed in place, its outer surface, together with the inner wall of the ventilation slot 601, forms a large heat dissipation area, constituting a composite structure similar to heat dissipation teeth. On the one hand, the heat dissipation boss 600 and the inner wall of the ventilation slot 601 achieve passive heat dissipation (increasing the heat dissipation area) through their contact with the external air. On the other hand, the ventilation slot 601, as a through airflow channel, can guide airflow to expel heat from the area of ​​the mounting platform 300, forming a coordinated convection with the heat dissipation tooth body 201 on the cover plate 200, thereby improving the overall heat dissipation efficiency.

[0049] This design allows the mounting platform 300 to flexibly adapt to different heat dissipation schemes according to the power of the equipment, which avoids structural redundancy in low-power scenarios and enhances the heat dissipation capability in the low-to-medium power range while retaining protection through the heat dissipation boss 600's heat dissipation tooth-like structure.

[0050] Specifically, a fixing plate 602 is provided on the upper part of the heat dissipation boss 600. The surface of the fixing plate 602 is provided with an insertion hole 603 that is coaxial with the threaded hole on the surface of the extension block 301. When the heat dissipation boss 600 abuts against the surface of the mounting platform 300, the lower surface of the fixing plate 602 can abut against the upper end face of the extension block 301, and the insertion hole 603 of the fixing plate 602 is coaxial with the threaded hole of the extension block 301. At this time, the heat dissipation boss 600 can be fixed by passing a bolt through the insertion hole 603 and threading it into the threaded hole.

[0051] Furthermore, the fixing plate 602 is located on the upper surface of the heat dissipation boss 600, and the ventilation slot 601 extends from the top surface of the fixing plate 602 to the bottom surface of the heat dissipation boss 600. When the heat dissipation boss 600 abuts against the mounting platform 300, the ventilation slot 601 and the surface of the mounting platform 300 form an airflow channel to ensure overall heat dissipation efficiency.

[0052] First, it should be clarified that this utility model relates to the field of electronic equipment protection, and is mainly used to improve the existing cover plate 200 with heat dissipation teeth. It should be noted that the internal structure of the housing 100 is the existing equipment, and the housing 100 and the cover plate 200 are fixed by screws or bolts, which is a common fixing method in the existing structure. Since this is not the innovation of this utility model, its internal structure will not be described in detail here. Only the usage method and installation position of the mounting platform 300 and the heat dissipation unit will be described in detail.

[0053] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
