Description

Technical Field

[0001] This utility model relates to the field of energy storage device technology, specifically to a heat dissipation structure for an energy storage device. Background Technology

[0002] Existing technology, patent CN217608156U, discloses a heat dissipation structure for an energy storage device, comprising: a power supply component, a power management module, a main control module, and an inverter module arranged sequentially from bottom to top. A first airflow channel is formed between the inverter module and the main control module, a second airflow channel is formed between the main control module and the power management module, and a third airflow channel is provided for the power supply component. A heat dissipation component is connected to the first, second, and third airflow channels. Its advantages are: the first and second airflow channels separate the modules, preventing heat conduction between them during operation and reducing heat accumulation; the third airflow channel facilitates the dissipation of heat from the power supply component during operation, preventing overheating; and the heat dissipation component dissipates heat generated by the inverter module, main control module, power management module, and power supply component, thereby improving the heat dissipation efficiency within the energy storage device.

[0003] The complex casing structure of this device, used to protect the energy storage battery, requires multiple cooling fans and air ducts for heat dissipation, which is not only inconvenient for manufacturing but also prone to malfunction. Furthermore, when the energy storage battery releases electrical energy, some of the energy is converted into heat, causing the battery's temperature to rise. The current device, relying solely on cooling fans, cannot adequately meet these cooling requirements. Therefore, a heat dissipation structure for energy storage devices is needed to meet these requirements. Based on actual usage, we have improved the aforementioned existing technology.

[0032] Please see Figure 1-5 This utility model provides a technical solution: a heat dissipation structure for an energy storage device.

[0033] Includes energy storage battery 1 and water-cooled heat dissipation mechanism 11;

[0034] The energy storage battery 1 is installed inside the outer casing 2, and a sealing plate 3 is provided on the top of the outer casing to protect the energy storage battery 1. Fixing bolts 4 are installed at the four corners of the sealing plate 3. The sealing plate 3 can be removed from the outer casing 2 to facilitate the maintenance and replacement of individual energy storage batteries 1 inside the outer casing 2. The outer casing 2 and the sealing plate 3 have a simple structure, which is easy to manufacture and also facilitates the centralized management of energy storage batteries 1. The front and rear ends of the outer casing 2 are provided with U-shaped mounting plates 7, and the inner cavity of the U-shaped mounting plates 7 is provided with exhaust fans 9. When the energy storage battery 1 is supplying power, the exhaust fans 9 can draw the heat emitted by the energy storage battery 1 from the heat dissipation holes on the outer casing 2, which can achieve the effect of air cooling of the energy storage battery 1. The side wall of the outer casing 2 is provided with an energy storage battery box 12, and the energy storage battery box 12 is provided with a power supply battery 13. In order to facilitate power supply, the exhaust fans 9, drive motor 101, pump 112 and return pump 116 are all powered by the power supply battery 13, which does not require an external power supply and is more convenient to use.

[0035] The water-cooled heat dissipation mechanism 11 includes a coolant tank 111 and a collection tank 115 installed on the outer walls of both sides of the outer casing 2. A heat absorption pipe 114 and a return pipe 118 are provided on the top of the coolant tank 111 and the collection tank 115.

The heat absorption pipe 114 and the return pipe 118 are both installed on the heat-conducting plate 6, and the heat-conducting plate 6 is installed on the top of the sealing plate 3. The heat generated by the energy storage battery 1 will be transferred to the outer casing 2, and the outer casing 2 will transfer the heat to the heat-conducting plate 6. At this time, the water-cooled heat dissipation mechanism 11 will carry away the heat accumulated on the heat-conducting plate 6, thereby achieving water-cooled heat dissipation of the energy storage battery 1. The heat dissipation effect of the energy storage battery 1 is good.

[0036] Preferably, a dustproof net 5 is provided on the side of the U-shaped mounting plate 7 near the outer shell 2, and a through hole 8 is provided on the side wall of the U-shaped mounting plate 7 away from the outer shell 2. The dustproof net 5 can prevent dust from entering the outer shell 2 through the heat dissipation holes. The through hole 8 can ensure that the rear side of the exhaust fan 9 has a ventilation effect and does not affect the operation of the exhaust fan 9.

[0037] Preferably, the exhaust fan 9 is mounted on the position adjustment mechanism 10. The position adjustment mechanism 10 includes an upper connecting frame 104 and a lower connecting frame 107. The outer ends of the upper connecting frame 104 and the lower connecting frame 107 are mounted on the outer wall of the exhaust fan 9.

The guide rod 105 is mounted on the U-shaped mounting plate 7.

[0039] If an instruction manual is required, please refer to [link / reference]. Figure 2 and Figure 3 The rotation of the drive motor 101 will drive the adjustment screw 102 to rotate. The rotation of the adjustment screw 102 will drive the screw sleeve 103 to move back and forth on the adjustment screw 102. The back and forth movement of the screw sleeve 103 will drive the upper connecting frame 104 to move back and forth. The back and forth movement of the upper connecting frame 104 will drive the exhaust fan 9 to move back and forth, thereby expanding the working range of the exhaust fan 9 and improving the heat dissipation effect of the exhaust fan 9. The guide sleeve 106 slides on the guide rod 105 to guide the movement of the lower connecting frame 107, thereby guiding the movement of the exhaust fan 9.

[0040] Preferably, a pump 112 is installed in the inner cavity of the coolant tank 111, and the inlet end of the pump 112 is connected to a first-level liquid extraction pipe 113, the bottom of the first-level liquid extraction pipe 113 extends to the bottom of the inner cavity of the coolant tank 111, the top outlet end of the pump 112 is connected to a heat absorption pipe 114, and the other end of the heat absorption pipe 114 extends to the bottom of the inner cavity of the collection tank 115.

[0042] It should be noted that you should refer to [link / reference]. Figure 4 and Figure 5 The coolant in the coolant tank 111 is pumped by pump 112 into the heat absorption pipe 114. The coolant flows rapidly in the heat absorption pipe 114, which can carry away the heat on the heat conduction plate 6, thus achieving water cooling of the energy storage battery 1. The cooling effect on the energy storage battery 1 is good. At the same time, the coolant will enter the collection tank 115 through the heat absorption pipe 114. The return pump 116 will pump the coolant in the collection tank 115 into the return pipe 118 through the second liquid extraction pipe 117, and then return it to the coolant tank 111 through the return pipe 118, so that the coolant can be reused.

[0043] Preferably, a first clamp 119 is installed on the return pipe 118 and is connected to the top of the heat-conducting plate 6. The heat-absorbing pipe 114 is curved and is arranged on the heat-conducting plate 6.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
