Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for energy storage power supplies, and in particular to a heat dissipation and airflow guiding structure for the outer shell of an energy storage power supply. Background Technology

[0002] With the widespread use of portable energy storage power supplies in outdoor activities, emergency backup, and other scenarios, the high-power electronic components such as battery packs and inverters integrated inside them generate a lot of heat during operation. If this heat cannot be dissipated in a timely and effective manner, it will seriously affect the working efficiency of the energy storage power supply and the service life of the internal components, and may even cause safety hazards.

[0003] To address the heat dissipation problem, existing energy storage power supply casings typically incorporate cooling fans to force air convection and remove internally generated heat. However, this simple cooling method has significant shortcomings. First, relying solely on fans for heat dissipation often results in suboptimal airflow paths, leading to heat buildup in certain areas and uneven, incomplete heat dissipation with limited overall efficiency. Second, while drawing in cool air, the cooling fans inevitably draw in dust, pollen, and other impurities from the external environment. This dust gradually adheres to the surfaces of heat sinks and electronic components, forming a heat insulation layer that significantly reduces heat dissipation performance. Long-term dust accumulation can also clog air ducts or affect fan rotation, ultimately causing the cooling system to fail. Existing dust prevention measures are usually quite simple, integrally molded with the casing, making regular cleaning and maintenance inconvenient for users.

[0004] Therefore, this utility model proposes a heat dissipation and airflow guiding structure for the outer shell of an energy storage power supply to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of heat dissipation and airflow guiding structure for energy storage power supply shell, which relies solely on fans for heat dissipation, easily leads to uneven heat dissipation, limited overall efficiency, and the heat dissipation air inlet is prone to significant performance degradation due to dust accumulation and is difficult to clean and maintain, this utility model aims to provide a heat dissipation and airflow guiding structure for energy storage power supply shell with improved structure that can effectively solve the above problems.

[0006] This utility model provides a heat dissipation and flow guiding structure for the outer casing of an energy storage power supply, including a casing, and a heat dissipation mechanism and flow guiding components disposed on the casing.

[0007] The heat dissipation mechanism includes: a U-shaped cavity disposed inside the housing for collecting heat; cooling fans disposed on both sides of the housing for promoting air circulation; heat sinks disposed on the upper part of the housing and in thermal communication with the U-shaped cavity; and air ducts for guiding hot airflow.

[0008] Furthermore, the top of the housing has a heat dissipation hole that communicates with the air duct, serving as a channel for hot air to be discharged.

[0009] The airflow guiding component is disposed on the side wall of the housing, and includes a through groove formed on the housing and a spiral plate disposed inside the through groove. The housing heats the air in the through groove, causing the air to rise, and guided by the spiral plate, a strengthened upward airflow is formed, achieving the effect of unpowered auxiliary heat dissipation.

[0010] Preferably, the air duct of the heat dissipation mechanism is defined by multiple parallel partitions, thereby forming multiple structurally stable and independent airflow channels.

[0011] Preferably, the heat dissipation and airflow guiding structure of the energy storage power housing further includes a dustproof mechanism, which is detachably installed outside the cooling fan of the heat dissipation mechanism.

[0012] Preferably, the dustproof mechanism includes a dustproof cover, and the dustproof cover is provided with a dustproof net for filtering dust.

[0013] Preferably, the housing is provided with a limiting ring for engaging and positioning with the dust cover, ensuring that the dust cover can be installed accurately and stably.

[0014] Preferably, the limiting ring is provided with a sealing strip to enhance the sealing performance, so as to ensure that the dust cover can fit tightly with the housing after installation.

[0015] Preferably, the dustproof mechanism further includes a locking component for locking the dust cover onto the limiting ring.

[0016] Preferably, the locking assembly includes a latch hinged to the housing, a buckle movably connected to the latch, and a base fixed to the dust cover and used for locking in conjunction with the buckle. This structure allows the dust cover to be easily disassembled and replaced.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model collects internal heat through a U-shaped cavity and actively dissipates heat with cooling fans on both sides. At the same time, it accelerates the discharge of hot air by using heat sinks, air ducts and heat dissipation holes on the top. Combined with the flow guiding components with spiral plates on the side wall of the shell for non-powered auxiliary heat dissipation, it solves the problems of single heat dissipation method and low heat dissipation efficiency in the existing energy storage power supply. It achieves the technical effect of combining active and passive heat dissipation, comprehensive and efficient heat dissipation, and ensuring stable operation of the equipment.

[0019] 2. This utility model solves the problem in the prior art that the heat dissipation structure is prone to performance degradation due to dust accumulation and is difficult to clean and maintain. It achieves the technical effect of effectively blocking dust, maintaining the heat dissipation system to work efficiently for a long time, and facilitating disassembly and replacement.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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 a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model provides a heat dissipation and airflow guiding structure for the outer casing of an energy storage power supply, which aims to solve the problems of insufficient heat dissipation efficiency and susceptibility to dust in the prior art.

[0029] like Figure 1 and Figure 2 As shown, the heat dissipation and airflow guiding structure of the energy storage power supply casing includes a casing 1, and a heat dissipation mechanism 2 and a dustproof mechanism 3 disposed on the casing 1. The casing 1 serves as the basic platform and main support of the entire device, and houses the energy storage power supply and is equipped with a key structure for heat dissipation. The heat dissipation mechanism 2 is used to efficiently handle the heat generated by the energy storage power supply during operation. The dustproof mechanism 3 is detachably installed at the key air intake part of the heat dissipation mechanism 2 to improve heat dissipation efficiency and extend the service life of the device.

[0030] The U-shaped cavity 201 of the heat dissipation mechanism 2 is fixedly opened inside the housing 1 to first collect the heat generated by the power supply. The cooling fan 202 is set at the corresponding opening on both sides of the housing 1 to accelerate the air circulation inside the U-shaped cavity 201 through active air supply. The upper part of the housing 1 is provided with multiple partitions 203, which are arranged in parallel to form an air duct 204. The heat sink 205 is connected to the U-shaped cavity 201 and conducts heat to the air duct 204. The air duct 204 further guides the hot air to flow out to the top of the housing 1. The top of the housing 1 is provided with a heat dissipation hole 206, which is connected to the air duct 204 and serves as the final channel for hot air to be discharged. In addition, the side wall of the housing 1 is also provided with a flow guiding component 207, which includes a through groove 2071 opened on the housing 1 and a spiral plate 2072 fixed inside the through groove 2071 to assist in achieving non-powered flow guiding heat dissipation.

[0031] To solve the above-mentioned technical problems, the technical solution of this embodiment is a specific detachable locking structure formed between the dustproof mechanism 3, the housing 1, and the heat dissipation mechanism 2.

[0032] Please refer to the following carefully. Figure 1 The structure will be described in detail below:

[0033] The dustproof mechanism 3 includes a dust cover 301. Inside the dust cover 301, a dustproof net 302 is integrally formed to intercept dust in the airflow. A limiting ring 303 for locking and positioning the dust cover 301 is fixedly welded to the housing 1. A sealing strip 304 is also fixed on the limiting ring 303. When the dust cover 301 is installed on the limiting ring 303, the sealing strip 304 is used to fill the gap between the two to ensure a sealing effect.

[0034] To prevent the dust cover 301 from falling off, the dustproof mechanism 3 also includes a locking component 305. The locking component 305 includes a latch 3051 hinged to both sides of the housing 1. The latch 3051 is movably connected to a buckle 3052. The outer wall of the dust cover 301 is fixed with a base 3053 for engaging with the buckle 3052. During installation, after the dust cover 301 is engaged with the limiting ring 303, the latch 3051 is pried open, and the buckle 3052 tightly engages with the base 3053, thereby completing the secure locking of the dust cover 301. This structure ensures that the dustproof mechanism 3 effectively filters dust while also facilitating subsequent disassembly, cleaning, and replacement.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0036] As a preferred embodiment, to further optimize the top heat dissipation efficiency, the air duct 204 of the heat dissipation mechanism 2 is defined by multiple partitions 203 arranged in parallel. These partitions 203 are preferably aluminum plates with good thermal conductivity and are fixedly connected to the inner top wall of the housing 1 by welding or integral molding, thereby forming multiple structurally stable and independent air circulation channels to ensure that the heat conducted from the heat sink 205 can be smoothly carried away by the airflow.

[0037] As another preferred embodiment, in order to enhance the sealing performance of the dustproof mechanism 3, a sealing strip 304 is provided on the limiting ring 303. The sealing strip 304 is preferably made of silicone rubber with good aging resistance and is embedded and fixed in the annular groove opened on the contact surface of the limiting ring 303 facing the dust cover 301, so as to ensure that the dust cover 301 can form a tight fit with the housing 1 after locking, effectively preventing dust from entering from the mating gap.

[0038] Working principle: The energy storage power supply generates a large amount of heat during use. To avoid affecting the working efficiency and safety stability of the device, the power supply casing 1 needs to have a heat dissipation mechanism 2 for heat dissipation. The heat generated by the internal power supply first accumulates in the U-shaped cavity 201 opened inside the casing 1. The internal air circulation is promoted by the cooling fans 202 on both sides of the casing 1 for initial heat dissipation. The upper part of the casing 1 is provided with an air duct 204 formed by multiple partitions 203. The rising heat in the U-shaped cavity 201 is transferred by multiple heat sinks 205 and quickly dissipated by the air duct 204. Some of the rising hot air escapes through the heat dissipation holes 206 opened at the top and exchanges heat with the outside air. Since the casing 1 itself transfers heat to the surroundings, the through slots 2071 opened on the casing 1 heat the internal air and form an upward trend. When passing through the internal spiral plate 2072, it is guided into a stronger upward airflow. The guide component 207 makes the air stay for a longer time, has more sufficient contact with the inner wall of the through slots 2071, and has better flow. It can dissipate heat quickly without power, making the device's heat dissipation more efficient and comprehensive, and reducing energy consumption.

[0039] Furthermore, dust accumulation during the heat dissipation process significantly affects heat dissipation efficiency. Therefore, setting up a dustproof mechanism 3 can improve the efficiency and service life of the heat dissipation mechanism 2. Removable dustproof covers 301 are installed at both ends of the two cooling fans 202. The dustproof covers 301 have dustproof nets 302 to intercept dust in the airflow. The dustproof covers 301 are securely mounted on the limiting rings 303. The limiting rings 303 are fixed with sealing strips 304 to ensure a sealing effect. In order to prevent them from falling off, locking components 305 are provided on both sides of the dustproof covers 301. After the dustproof covers 301 are locked with the limiting rings 303, the buckles 3051 located on both sides of the housing 1 are pried open so that the buckles 3052 are tightly fastened to the bases 3053 located on both sides of the dustproof covers 301, thus completing the fixation. The dustproof covers 301 and the heat dissipation holes 206 can prevent most of the dust from entering the interior of the heat dissipation mechanism 2 and are easy to disassemble and replace.
