Description

Technical Field

[0001] This invention relates to the field of power supply housings, specifically to heat dissipation housings for energy storage power supplies. Background Technology

[0002] An energy storage power supply is a high-capacity portable power source, a device that can store electrical energy. It has an AC 220V output, can drive low-power electrical appliances, can be used for lighting, can be used with power outlets, and can charge various electrical appliances.

[0003] Most existing energy storage power supplies consist of a metal casing enclosing the battery control panel and the battery body. Since the battery control panel generates a lot of heat during the charging and discharging process of the battery, in order to prevent the heat generated by the battery control panel from being conducted to the battery and affecting the normal operation of the battery, most existing energy storage devices use a cooling method of heat dissipation holes in combination with fans.

[0004] In practical use, existing energy storage batteries often require handles on the casing to facilitate user transport. However, handles on the casing can negatively impact the aesthetics of the casing, and protruding handles can hinder packaging and transportation. Furthermore, the ventilation holes on the casing are often simply drilled directly into the casing wall. When the internal fan is operating, it can easily draw dust from the outside into the casing, reducing the dustproof capability of the energy storage power supply. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a heat dissipation housing for energy storage power supplies to solve the technical problem of poor dust protection capability of existing energy storage battery housings.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heat dissipation shell for an energy storage power supply, comprising a housing, an upper part of which is provided with a mounting plate, a main control circuit board mounted on the mounting plate, an air inlet and an air outlet respectively provided on both sides of the upper part of the housing, an air inlet handle box provided inside the air inlet of the housing, and an air outlet handle box provided inside the air outlet of the housing, both the air inlet handle box and the air outlet handle box being hollow L-shaped structures, and an exhaust fan provided inside the housing on one side of the air outlet handle box.

[0007] By adopting the above technical solution, air inlets and outlets are set on both sides of the casing, and embedded handle structures are set at the air inlets and outlets respectively. Dustproof mesh is set inside the handle structure, so that the handle and heat dissipation vent on the casing are integrated, which improves the aesthetics of the power supply casing. At the same time, it makes it difficult for external dust to enter the casing through the embedded handle structure, thus improving the dustproof effect of the power supply casing.

[0008] The present invention is further configured such that the main control circuit board is provided with multiple sets of heat dissipation fins, all of which are orthogonal to the plane of the air inlet and the air outlet.

[0009] By adopting the above technical solution, multiple sets of heat dissipation fins efficiently dissipate heat from the main control circuit board, and the air flow from the air inlet and outlet accelerates the heat dissipation speed of the main control circuit board.

[0010] The present invention is further configured such that both the air inlet handle box and the air outlet handle box are provided with filter structures.

[0011] By adopting the above technical solution, the filter structure can effectively prevent a large amount of dust from entering the housing through the air inlet handle box and the air outlet handle box.

[0012] The present invention is further configured such that the housing has an exhaust chamber at the air outlet handle box, and an inclined exhaust fan is provided on the exhaust chamber.

[0013] By adopting the above technical solution, the inclined exhaust fan effectively utilizes the space where the main control circuit board is installed in the housing, avoiding the problem that traditional vertically installed exhaust fans are partially blocked by the main control circuit board and cannot efficiently flow air. This ensures that there are no obstructions at the air inlet of the inclined exhaust fan, and the rising hot air can be efficiently discharged by the exhaust fan in the housing along with the airflow entering through the air inlet.

[0014] The present invention is further configured such that a baffle is rotatably connected to the bottom end of the air outlet handle box via a drive structure.

[0015] By adopting the above technical solution, the baffle can control the direction of the airflow out of the housing, allowing the airflow to exit the housing through different channels under different usage environments.

[0016] The invention is further configured such that the housing has side air ducts on both sides of the battery, the mounting plate has an opening communicating with the side air ducts, the exhaust chamber has a guide plate, the bottom end of the guide plate is connected to the opening of the side air duct, and the top end is connected to the bottom end of the exhaust fan. When the baffle is parallel to the ground, it contacts the guide plate. When the baffle is parallel to the ground, the airflow from the exhaust fan flows to the air outlet. When the baffle is perpendicular to the ground, the airflow from the exhaust fan flows to the side air duct.

[0017] By adopting the above technical solution, by controlling the baffle to rotate parallel to the ground, the airflow can flow directly out through the air outlet. By controlling the baffle to rotate orthogonally to the ground, the airflow can flow through the two sets of side air ducts at the bottom of the shell and the bottom of the shell before flowing out through the side air duct outlet.

[0018] The present invention is further configured such that a temperature sensor is provided on the main control circuit board, and the temperature sensor is connected to the control circuit on the main control circuit board.

[0019] By adopting the above technical solution, the temperature detected by the temperature sensor determines whether the baffle needs to be rotated.

[0020] The present invention is further configured such that multiple heat pipes are installed at both the front and rear ends of the battery via a bracket structure.

[0021] By adopting the above technical solution, the heat pipe can quickly and efficiently carry the heat of the hot air to the side of the battery, thereby warming the battery.

[0022] The present invention is further configured such that an air duct outlet is provided at the bottom end of the side air duct on the air inlet side of the housing.

[0023] By adopting the above technical solution, the airflow that passes through the two sets of side air ducts and the bottom of the shell flows out of the shell through the air duct outlet.

[0024] In summary, the present invention has the following main beneficial effects:

[0025] 1. This invention provides air inlets and outlets on both sides of the housing, and embeds handle structures at the air inlets and outlets respectively. A dustproof mesh is installed inside the handle structure, so that the handle and heat dissipation vent on the housing are integrated, which improves the aesthetics of the power supply housing. At the same time, it makes it difficult for external dust to enter the housing through the embedded handle structure, thus improving the dustproof effect of the power supply housing.

[0026] 2. This invention effectively utilizes the space where the control panel is installed in the housing by setting an inclined exhaust fan structure at the air outlet of the housing. This avoids the problem that traditional vertically set exhaust fans are partially blocked by components on the control panel and cannot efficiently flow air. The inclined exhaust fan has no obstructions at the air inlet, so that the rising hot air can be efficiently discharged from the housing by the exhaust fan along with the airflow entering through the air inlet.

[0027] 3. This invention incorporates an air duct structure at the bottom of the housing and a rotating baffle structure at the exhaust fan. When the energy storage battery is charging at an ambient temperature lower than a set value, the baffle automatically rotates to block the air outlet. The heat generated by the main control circuit board is guided into the air duct through the air duct's air guiding structure. The hot air flowing into the air duct comes into full contact with multiple heat pipes, which carry the heat to the surrounding area of ​​the battery, raising the battery's temperature during charging and alleviating the problems of reduced battery capacity and slow charging speed caused by low ambient temperatures.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of the present invention will now be described.

[0038] Heat dissipation casing for energy storage power supplies, such as Figure 1-6 As shown, the device includes a housing 1, with a mounting plate 3 on the upper part of the housing 1. A main control circuit board 8 is mounted on the mounting plate 3. A side cover 2 is connected to the front end of the housing 1, which keeps the interior of the housing 1 relatively sealed. Multiple interfaces 20 are provided at the rear end of the housing 1 for connecting the main control circuit board 8 to the outside environment. Air inlets 4 and air outlets 5 are provided on the upper two sides of the housing 1, respectively. An air inlet handle box 6 is provided inside the air inlet 4, and an air outlet handle box 7 is provided inside the air outlet 5. Both the air inlet handle box 6 and the air outlet handle box 7 are hollow L-shaped structures. The hollow L-shaped structure can fit well with the user's fingers, allowing the user to easily lift the device through the air inlet handle box 6 and the air outlet handle box 7. An exhaust fan 10 is provided on one side of the air outlet handle box 7 inside the housing 1. The exhaust fan 10 drives the air flow, allowing outside air to enter the housing 1 through the air inlet 4 and then flow out of the housing 1 through the air outlet 5.

[0039] Based on the above structure, in this embodiment, the main control circuit board 8 is provided with multiple sets of heat dissipation fins. All sets of heat dissipation fins are orthogonal to the plane of the air inlet 4 and the air outlet 5. The multiple sets of heat dissipation fins efficiently dissipate the heat on the main control circuit board 8. Combined with the air flow of the air inlet 4 and the air outlet 5, the heat dissipation speed of the main control circuit board 8 is accelerated. Furthermore, in order to meet the air flow requirements of the exhaust fan 10, both ends of the heat dissipation fins are provided with rounded chamfers so that the gas entering the housing 1 can flow efficiently.

[0040] Both the air inlet handle box 6 and the air outlet handle box 7 are equipped with filter structures, which can effectively prevent a large amount of dust from entering the housing 1 through the air inlet handle box 6 and the air outlet handle box 7.

[0041] Based on the above structure, in this embodiment, the housing 1 is provided with an exhaust chamber 9 at the air outlet handle box 7, and an inclined exhaust fan 10 is provided on the exhaust chamber 9. The inclined exhaust fan 10 effectively utilizes the space where the main control circuit board 8 is installed on the housing 1, avoiding the problem that the traditional vertically set exhaust fan will be partially blocked by the main control circuit board 8 and cannot efficiently flow air. This ensures that there are no obstructions at the air inlet of the inclined exhaust fan 10, and the rising hot air can be efficiently discharged by the exhaust fan 10 in the housing 1 along with the airflow entering through the air inlet 4.

[0042] Based on the above structure, in this embodiment, the bottom end of the air outlet handle box 7 is rotatably connected to a baffle 12 via a drive structure. The drive structure specifically includes a micro motor 11, which is mounted on the outer wall of the exhaust chamber 9, and its output end is connected to the rotating shaft of the baffle 12. The main control circuit board 8 controls the operation of the micro motor 11 to control the rotation of the baffle 12. The baffle 12 can control the flow direction of the airflow out of the housing 1, allowing the airflow to exit the housing 1 through different channels under different usage environments. When the ambient temperature is higher than the threshold temperature set by the temperature sensor, When the baffle 12 does not rotate, the external airflow passes through the air inlet 4, enters the housing 1, and exits through the air outlet 5, cooling the main control circuit board 8 and carrying its heat out of the housing 1. When the ambient temperature of the outdoor unit is lower than the threshold temperature set by the temperature sensor, the main control circuit board 8 controls the micro motor 11 to work, causing the baffle 12 to rotate and block the exhaust port on the air outlet handle box 7. At this time, the airflow blown by the exhaust fan 10 is guided by the air guide arc plate 13 and enters the side air duct 14 through the opening set in the side air duct 14 on the mounting plate 3. Hot airflow heats one side of the battery 16. When the hot airflow reaches the lower end of the battery 16, it causes a phase change in the phase change medium within multiple heat pipes 17. The heat pipes 17 efficiently carry the heat from the hot air to the front and rear ends of the battery 16, heating the battery 16. Then, the hot air heats the other side of the battery 16 through another set of side air ducts 14, and finally flows out from the air duct outlet 18. The housing 1 has side air ducts 14 on both sides of the battery. The mounting plate 3 has openings connecting to the side air ducts 14. The exhaust chamber 9 has a guide plate 13. The bottom end of the baffle 12 is connected to the opening of the side air duct 14, and the top end is connected to the bottom end of the exhaust fan 10. When the baffle 12 is parallel to the ground, it contacts the air guide arc plate 13. When the baffle 12 is parallel to the ground, the airflow through the exhaust fan 10 flows to the air outlet 5. When the baffle 12 is perpendicular to the ground, the airflow through the exhaust fan 10 flows to the side air duct 14. By controlling the rotation of the baffle 12 to be parallel to the ground, the airflow flows directly out through the air outlet 5. By controlling the rotation of the baffle to be perpendicular to the ground, the airflow flows through the two sets of side air ducts at the bottom of the housing 1 and the bottom end of the housing 1, and then flows out through the side air duct outlet 18.

[0043] Based on the above structure, in this embodiment, the main control circuit board 8 is equipped with a temperature sensor and a microcontroller storing control logic. The temperature sensor transmits the external temperature value signal to the microcontroller. The microcontroller determines whether the temperature is less than or equal to a threshold. When the temperature is less than or equal to the threshold, it sends a forward rotation signal to the micro motor 11, causing the baffle 12 to block the air outlet handle box 7. When the temperature is greater than the threshold, it sends a reverse rotation signal to the micro motor 11, causing the baffle 12 to contact the air guide arc plate 13, so that the airflow at the air outlet handle box 7 flows smoothly. The threshold temperature is specifically ten degrees Celsius.

[0044] To prevent the main control circuit board 8 from directly conducting heat to the battery 16, a heat insulation plate 19 is provided at the bottom of the mounting plate 3 inside the housing 1.

[0045] Based on the above structure, in this embodiment, multiple sets of heat pipes 17 are installed at both the front and rear ends of the battery 16 through a bracket structure. The heat pipes 17 are preferably L-shaped flat heat pipes, which are fixed to the housing 1 and the side cover 2 respectively through the bracket structure. The heat pipes 17 can quickly and efficiently bring the heat of the hot air to the side of the battery 16 to heat up the battery 16. A support frame 15 is provided at the bottom of the housing 1. The support frame 15 can effectively support the battery 16 and prevent the battery 16 from crushing the heat pipes 17.

[0046] Based on the above structure, in this embodiment, the housing 1 has an air duct outlet 18 at the bottom end of the side air duct 14 on the side of the air inlet 4. The airflow after passing through the two sets of side air ducts 14 and the bottom end of the housing 1 flows out of the housing 1 through the air duct outlet 18.

[0047] To improve the heating efficiency of the battery at low temperatures, the inner walls of the casing 1 and the side cover 2 below the mounting plate 3 are wrapped with thermal insulation cotton, so that the heat emitted from the main control circuit board 8 can efficiently heat the battery 16, thereby improving its charging speed and the upper limit of its stored capacity in cold environments.

[0048] This invention creatively integrates the handle and heat dissipation vents, avoiding the shortcomings of existing energy storage battery casings with poor dust protection. In this solution, air inlets and outlets are provided on both sides of the casing, and embedded handle structures are provided at the air inlets and outlets respectively. A dustproof mesh is installed inside the handle structure, making the handle and heat dissipation vents on the casing integrated, improving the aesthetics of the power supply casing, and at the same time preventing external dust from easily entering the casing through the embedded handle structure, thus improving the dust protection effect of the power supply casing.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
