Description

Technical Field

[0001] This utility model relates to the field of mobile power generation and supply equipment technology, specifically a fully enclosed heat dissipation structure for a portable power supply device. Background Technology

[0002] Portable power supply equipment mainly includes four categories: portable power stations, generator sets driven by internal combustion engines, solar power stations, and welding machines. These equipment have wide applications, such as backup power, emergency power, power supply in areas with power shortages, power generation, and material welding. Power supply equipment primarily consists of a power generation unit and a casing. During operation, the internal inverter, battery pack, and controller generate heat. Existing power generation units often employ forced air cooling structures. This requires air inlets and outlets in the casing, which directly expose the inverter, battery pack, and controller to the outside atmosphere. External moisture, dust, and various foreign objects can easily enter the casing, significantly impacting the reliability and lifespan of the power supply equipment. Furthermore, the metal casings of existing portable power supply equipment are bulky and expensive, making them unsuitable for portable applications. Utility Model Content

[0003] The purpose of this invention is to provide a fully enclosed heat dissipation structure for portable power supply devices. Addressing the shortcomings of existing heat dissipation structures and housing designs for portable power supply devices, a fully enclosed housing heat dissipation structure has been developed for the power generation device of portable power supply devices. This structure can effectively prevent the intrusion of external moisture, dust, and other foreign objects while ensuring heat dissipation, significantly improving the operational reliability and service life of the power supply device. At the same time, it can ensure heat dissipation while using a plastic housing, achieving the effects of weight reduction, improved portability, and cost reduction.

[0004] This utility model is implemented as follows: A fully enclosed heat dissipation structure for a portable power supply device includes a power generating device and a housing. The power generating device is disposed inside the housing, and the housing is used to enclose the power generating device. The power generating device includes at least one heat-generating component that generates heat during operation. The heat-generating component is connected to a heat-conducting plate. A heat sink is disposed outside the housing, and the heat-generating component is connected to the heat sink through the heat-conducting plate. A pull rod device is disposed outside the housing, and a roller device is disposed at the bottom of the housing. The heat sink is disposed between the pull rod device and the housing.

[0005] Furthermore, the bottom of the housing is provided with an opening, the size of which is larger than the size of the heat-conducting plate. The heat-conducting plate passes through the opening and is connected to the heat sink, thereby conducting the heat generated by the heat-generating components to the heat sink outside the housing.

[0006] Furthermore, a first sealing ring is provided between the heating element and the housing, and a second sealing ring is provided between the radiator and the housing, forming an inner and outer double-layer sealing isolation at the opening of the housing, ensuring that the entire housing is in a fully enclosed state.

[0007] Furthermore, the radiator includes a heat sink and a fan. The heat sink has multiple parallel heat sink fins. The heat sink and its heat sink fins are made of a metal material with good thermal conductivity. The heat sink has a mounting area in the middle where no heat sink fins are installed, and the fan is installed in this mounting area.

[0008] Furthermore, a partition is provided between the radiator and the pull rod device, the partition being located on top of the radiator fins and made of metal.

[0009] Furthermore, the heat-conducting plate is made of a metal material with good thermal conductivity, and a thermally conductive agent or a thermally conductive silicone pad is provided between the heat-conducting plate and the heating element to ensure good thermal conductivity between the heat-conducting plate and the heating element.

[0010] Furthermore, a thermally conductive agent or a thermally conductive silicone pad is provided between the heat sink and the heat-conducting plate to ensure good thermal conductivity between the heat sink and the heat-conducting plate.

[0011] Furthermore, the pull rod device, partition, heat sink plate and housing are connected by screw assembly. The heating component is provided with studs around its periphery. The studs pass through the first sealing ring, housing, second sealing ring and heat sink plate in sequence. Nuts are installed on the studs and are screwed and pressed onto the heat sink plate.

[0012] Furthermore, the housing is provided with multiple connecting posts, each with a threaded hole at its top. The heat sink is provided with through holes corresponding to each connecting post, and each connecting post passes through its corresponding through hole. The screw assembly includes stepped screws and connecting screws. The shank of the stepped screw passes through a partition and connects to the threaded hole at the top of the connecting post. The inner wall of the pull rod device is provided with receiving grooves corresponding to each stepped screw for accommodating the head of each stepped screw. The outer wall of the pull rod device is provided with guide connecting holes leading to the receiving grooves. The head of the stepped screw is provided with a threaded connecting hole, and the shank of the connecting screw passes through the guide connecting hole and connects to the threaded connecting hole at the head of the stepped screw.

[0013] Furthermore, the power generating device includes a battery and a converter, wherein the heating component is either the battery or the converter, and the converter is either an inverter or a charger. The inverter converts the direct current (DC) from the battery into alternating current (AC) output, and the charger converts the externally input DC or AC power into DC power of a specific voltage and current to charge the battery.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a special closed heat conduction structure between the heating component of the power generation device and the heat sink outside the casing. Heat is conducted through a metal heat conduction plate that is in close contact with the heating component. The heat conduction plate passes through the opening set on the casing and is tightly connected to the heat sink outside the casing. This heat dissipation structure is not limited by the casing material. Whether it is a metal casing or a plastic casing, it can achieve good heat dissipation effect.

[0015] 2. This utility model places the heat sink between the housing and the pull rod device, greatly improving the protective effect and safety of the heat dissipation structure while ensuring the portability of the equipment. Since the housing material of this utility model does not affect the heat dissipation effect, a plastic housing can be used. Plastic housings are significantly lighter and less expensive than metal housings. Power supply equipment designed using this utility model has obvious advantages such as high protection level, good heat dissipation, light weight, low cost, and aesthetically pleasing appearance, making it very suitable for various portable power supply equipment products and possessing significant technical advantages.

[0016] 3. This utility model is equipped with both a first sealing ring and a second sealing ring. The first and second sealing rings form an inner and outer double-layer seal at the opening of the casing, ensuring that the entire casing is in a fully enclosed state. This effectively prevents external moisture, dust, and other foreign objects from intruding while ensuring heat dissipation, significantly improving the reliability and service life of the power supply equipment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: like Figures 1-4 as well as Figure 8 As shown, a fully enclosed heat dissipation structure for a portable power supply device includes a power generation device and a housing 1. The power generation device is disposed inside the housing 1, which is used to enclose it. The housing 1 includes an upper housing 102 and a lower housing 103. A rubber gasket or other sealing element is provided between the upper housing 102 and the lower housing 103 to improve the sealing effect of the housing 1. The power generation device includes a battery 12 and a converter. The power generation device includes at least one heat-generating component 13 that generates heat during operation. The heat-generating component 13 is either the battery 12 or the converter. In this embodiment, it is the converter, which is either an inverter or a charger. Inverters or chargers generally generate a large amount of heat. If the power supply device has an AC output, the converter is an inverter, which can convert the DC power from the battery into AC power output with a specific voltage and frequency. When the power supply device has no AC output and only a DC output, an inverter is not needed, and the converter is simply a charger. The charger is responsible for converting the externally input DC or AC power into DC power with a specific voltage and current to charge the battery. Of course, depending on the needs, the inverter and charger can also be integrated into one unit, in which case the converter becomes a bidirectional inverter. An electrical panel 8 is provided on the outside of the casing 1. Various input / output sockets and interfaces are installed on the electrical panel 8, and the control switch and display screen are also installed on the electrical panel 8.

[0020] like Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, the heating element 13 is connected to a heat-conducting plate 2, and a heat sink 3 is installed on the outside of the casing 1. The heat-conducting plate 2 is made of a metal material with good thermal conductivity, such as aluminum alloy. An opening 101 is provided at the bottom of the lower casing 103. The size of the opening 101 is larger than the size of the heat-conducting plate 2, and the size of the heat sink 3 is larger than the size of the opening 101. The heat-conducting plate 2 passes through the opening 101 and is connected to the heat sink 3, thus allowing the heating element 13 to be thermally connected to the heat sink 3 through the heat-conducting plate 2, thereby transferring the heat generated by the heating element 13 to the heat sink 3 outside the casing 1.

[0021] If necessary, a thermally conductive agent or a thermally conductive silicone pad can be placed between the heat-conducting plate 2 and the heating element 13 to ensure good thermal conductivity between them. A thermally conductive agent or a thermally conductive silicone pad is also placed between the radiator 3 and the heat-conducting plate 2 to ensure good thermal conductivity between them. The thermally conductive silicone pad can be made of high-temperature resistant methyl vinyl silicone rubber filled with a mixture of alumina and aluminum nitride, which has excellent temperature resistance, thermal conductivity, and insulation. The high thermal conductivity inorganic filler significantly improves the thermal conductivity of the silicone pad, ensuring that the heat generated by the heating element 13 is efficiently conducted to the heat-conducting plate 2. The methyl vinyl silicone rubber substrate gives the silicone pad good elasticity, allowing it to fully fill the tiny gaps between the heat-conducting plate 2 and the heating element 13, eliminating the obstruction of heat dissipation by air layers.

[0022] like Figure 2 , Figure 5 and Figure 7 As shown, a first sealing ring 5 is provided between the heating element 13 and the housing 1, surrounding the opening 101, and a second sealing ring 6 is provided between the radiator 3 and the housing 1, surrounding the opening 101. Both the first sealing ring 5 and the second sealing ring 6 are made of rubber material. The first sealing ring 5 and the second sealing ring 6 form an inner and outer double-layer sealing isolation at the opening 101 of the housing 1, ensuring that the entire housing 1 is in a fully enclosed state.

[0023] It should be noted that when the casing 1 is a metal casing, since the metal casing itself has good thermal conductivity, the heat conduction plate 2 can be integrated with the casing 1, and the casing 1 does not need to have an opening 101, nor does it need to be equipped with a sealing ring.

[0024] like Figure 5 , Figure 6 and Figure 9As shown, the heat sink 3 includes a heat sink 301 and a fan 302. The heat sink 301 has multiple parallel-arranged heat sink fins 303. The heat sink 301 and its heat sink fins 303 are made of a metal material with good thermal conductivity, such as aluminum alloy. The heat sink 301 has a mounting area 304 in the middle where no heat sink fins 303 are installed. The fan 302 is installed in this mounting area 304. The fan 302 can accelerate the airflow speed at the heat sink 301 and heat sink fins 303, enabling the heat sink 3 to maintain a lower temperature and efficiently dissipate the heat generated by the heat-generating components 13 inside the casing 1 to the outside.

[0025] like Figure 1-5 as well as Figure 7 As shown, a pull rod device 4 is provided on the outside of the housing 1. The pull rod device 4 is a pull-out type. A roller device 9 is provided at the bottom of the housing 1, which makes the power supply equipment easy to move. Since the heat sink 3 is large in size and has sharp heat sink fins 303 on the outside, the heat sink 3 is placed between the pull rod device 4 and the housing 1 to prevent damage. The presence of the heat sink 3 does not affect the use of the pull rod device 4 and the roller device 9, and the pull rod device 4 is cleverly used to protect the heat sink, improving the safety of use. At the same time, in order to further improve the heat dissipation and protection effect, a metal partition 7 can be provided between the heat sink fins 303 and the pull rod device 4. The partition 7 helps to enhance the heat dissipation effect of the heat sink 3 and also protects the inside of the pull rod device 4.

[0026] like Figure 2 , Figure 5 as well as Figures 7-9As shown, the pull rod device 4, partition 7, heat sink 301, and housing 1 are connected by a screw assembly. The housing 1 has multiple connecting posts, each with a threaded hole at its top. The heat sink 301 has through holes corresponding to each connecting post, through which each connecting post passes. The screw assembly includes stepped screws 14 and connecting screws 15. The shank of the stepped screw 14 passes through the partition 7 and connects to the threaded hole at the top of the connecting post. The inner wall of the pull rod device 4 has receiving grooves corresponding to each stepped screw 14 for accommodating its head. The outer wall of the pull rod device 4 has guide connecting holes leading to the receiving grooves. The head of the stepped screw 14 has a threaded connecting hole, and the shank of the connecting screw 15 passes through the guide connecting hole and connects to the threaded connecting hole at the head of the stepped screw 14. The heating element 13 is surrounded by studs 10, which pass through the first sealing ring 5, the housing 1, the second sealing ring 6, and the heat sink 301 in sequence. Nuts 11 are installed on the studs 10 and are tightened onto the heat sink 301. Additionally, the heating element 13 has studs 10 in the middle for mounting the heat-conducting plate 2. These studs 10 pass through the heat-conducting plate 2 and the heat sink 301 in sequence and are connected together by nuts 11 on the outside of the heat sink. This achieves a stable assembly of the housing 1, the first sealing ring 5, the second sealing ring 6, the heat-conducting plate 2, the heat sink 3, the partition 7, and the pull rod device 4. This ensures a fully enclosed interior of the housing 1 to protect the power generating device, while the efficient heat conduction of the heat-conducting plate 2 and the heat sink 3 continuously dissipates heat from the heating element 13 to the outside. The pull rod device 4 and the partition 7 also provide protection for the heat sink 3, balancing portability, heat dissipation, and safety.

[0027] In summary, this utility model designs a special closed heat conduction structure between the heating component 13 of the power generation device and the heat sink 3 outside the housing 1. Heat is conducted through a metal heat conduction plate 2 that is in close contact with the heating component 13. The heat conduction plate 2 passes through the opening 101 provided on the housing 1 and is tightly connected to the heat sink 3 outside the housing 1. This heat dissipation structure is not limited by the material of the housing 1. Whether the housing is made of metal or plastic, it can achieve good heat dissipation.

[0028] This invention places the heat sink 3 between the housing 1 and the pull rod device 4, greatly improving the protective effect and safety of the heat dissipation structure while ensuring the portability of the equipment. Since the housing material of this invention does not affect the heat dissipation effect, a plastic housing can be used. Plastic housings are significantly lighter and less expensive than metal housings. Power supply equipment designed using this invention has obvious advantages such as high protection level, good heat dissipation, light weight, low cost, and aesthetically pleasing appearance, making it very suitable for various portable power supply equipment products and possessing significant technical advantages.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
