Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an integrated lower housing for a liquid-cooled energy storage PACK. Background Technology

[0002] Compared to traditional air cooling and other methods, the liquid-cooled energy storage PACK integrated lower enclosure utilizes a highly efficient liquid cooling system. The coolant can precisely remove the heat generated by the energy storage PACK during operation, significantly improving heat dissipation efficiency and better maintaining a suitable operating temperature to ensure the stable operation of the energy storage system.

[0003] In existing liquid-cooled energy storage PACK enclosure structures, the exterior is generally sealed. Because the exterior is typically sealed, high temperatures can accumulate inside the equipment during long-term operation. This high temperature cannot dissipate quickly enough, which can negatively impact the equipment's normal operation. Utility Model Content

[0004] Based on this, the present invention provides an integrated lower enclosure for a liquid-cooled energy storage PACK, which aims to solve the problem that the existing liquid-cooled energy storage PACK enclosure structure cannot dissipate the heat generated inside in a timely manner, thus affecting the normal operation of the equipment.

[0005] To achieve the above objectives, the present invention proposes the following technical solution: an integrated lower housing for a liquid-cooled energy storage PACK, comprising a housing body; a plurality of heat dissipation holes penetrating the side wall are provided on one side wall of the housing body; and a heat dissipation mechanism is provided on the outer side of the side wall.

[0006] The heat dissipation mechanism includes a connecting plate and a slider. The slider is slidably connected to the top of the connecting plate, and the connecting plate is disposed on the outer side of the side wall. A moving groove is provided inside the connecting plate. A connecting rod is provided at the bottom of the slider, and the connecting rod is slidably connected to the moving groove. A sealing plate is provided at the end of the connecting rod away from the slider. A snap-fit ​​rod is provided on the side of the sealing plate. A positioning hole adapted to the snap-fit ​​rod is provided on the side wall.

[0007] In a preferred embodiment, the sealing plate is provided with the snap-fit ​​rods on both sides, and the two snap-fit ​​rods are symmetrically arranged; the snap-fit ​​rods are arranged in a one-to-one correspondence with the positioning holes; the sealing plate is adapted to the heat dissipation holes.

[0008] In a preferred embodiment, the plurality of heat dissipation holes are evenly distributed; the sealing plate is slidably connected to the outside of the heat dissipation holes via the connecting rod.

[0009] In a preferred embodiment, when the temperature inside the housing is at room temperature, the snap-fit ​​rod is engaged in the positioning hole, and the sealing plate covers the heat dissipation hole. The snap-fit ​​rod engages in the positioning hole, ensuring the sealing plate is stably positioned over the outside of the heat dissipation hole, thus providing a seal. When the sealing plate moves via the connecting rod, it opens the heat dissipation hole, allowing for heat dissipation from the inside of the housing.

[0010] In a preferred embodiment, a first reset spring is provided on the outer side of the connecting rod near the moving groove, and the first reset spring is housed within the moving groove; the first reset spring is connected to the end of the moving groove away from the side wall.

[0011] In a preferred embodiment, a pressure box is provided on the inner side of the sidewall, and an air inlet is provided on the pressure box; a sliding plate is slidably connected inside the pressure box; multiple second return springs are provided on the side of the sliding plate away from the air inlet; one end of the second return spring is connected to the sliding plate, and the other end is connected to the inner wall of the pressure box.

[0012] In a preferred embodiment, a push rod is also provided on the side of the sliding plate away from the air inlet, and several second return springs are evenly arranged on the outer side of the push rod; one end of the push rod is connected to the sliding plate, and the other end passes through the pressure box and the side wall in sequence before being movably connected to the slider. With this arrangement, when the push rod moves, it will push the slider at the top of the connecting plate.

[0013] In a preferred embodiment, a pressing rod is provided on the side of the slider; a fan mechanism is also provided on the outer side of the sidewall, and the fan mechanism is provided in a one-to-one correspondence with the pressing rod; one end of the pressing rod is fixedly connected to the side of the slider, and the other end is movably connected to the fan mechanism.

[0014] In a preferred embodiment, the fan mechanism includes a stabilizing plate disposed on the side wall; a power supply box is disposed on the top of the stabilizing plate; a switch is disposed on the side of the power supply box, and a third reset spring is disposed inside the switch; a motor is disposed at the bottom of the stabilizing plate, a rotating shaft is disposed at the output end of the motor, and a fan blade is disposed at the end of the rotating shaft away from the motor.

[0015] In a preferred embodiment, the motor is electrically connected to the power supply box; one end of the third return spring is fixed to the inner wall of the switch, and the other end is movably connected to the switch button; the button is movably connected to the pressing rod. When the switch is turned on, the power supply box will start the motor, thereby driving the fan blades at the bottom of the shaft to rotate.

[0016] In a preferred embodiment, two fan mechanisms are provided, symmetrically arranged on both sides of the connecting plate; the switch of each fan mechanism is oriented towards the corresponding pressing rod. When the slider moves, it drives the pressing rod to move, thus the pressing rod exerts a pushing force on the switch.

[0017] The beneficial effects achieved by this utility model are as follows: By providing heat dissipation holes, a heat dissipation mechanism, and a fan mechanism on the side wall of the housing body, and by installing a pressure box adapted to the heat dissipation mechanism inside the housing body, the high-temperature heat generated inside the housing body due to operation can be promptly discharged to the outside of the housing body, effectively dissipating heat from the inside of the housing body and ensuring the normal and stable operation of the energy storage system.

The snap-fit ​​rod 35 engages in the positioning hole 40, ensuring the sealing plate 34 is stably positioned over the outside of the heat dissipation hole 20, thus providing a seal. When the sealing plate 34 moves via the connecting rod 33, the heat dissipation hole 20 is opened, allowing for heat dissipation from the inside of the housing body 10.

[0034] In a preferred embodiment, a first return spring 331 is provided on the outer side of the connecting rod 33 near the moving groove 311, and the first return spring 331 is housed in the moving groove 311; the first return spring 331 is connected to the end of the moving groove 311 away from the side wall 11.

With this configuration, when the push rod 54 moves, it will push the slider 32 on the top of the connecting plate 31.

[0037] In a preferred embodiment, a pressing rod 321 is provided on the side of the slider 32; a fan mechanism 60 is also provided on the outer side of the sidewall 11, and the fan mechanism 60 is provided in a one-to-one correspondence with the pressing rod 321; one end of the pressing rod 321 is fixedly connected to the side of the slider 32, and the other end is movably connected to the fan mechanism 60.

[0040] In a preferred embodiment, two fan mechanisms 60 are provided, symmetrically arranged on both sides of the connecting plate 31; the switch 63 of each fan mechanism 60 is oriented towards the corresponding pressing rod 321. When the slider 32 moves, it drives the pressing rod 321 to move, thus the pressing rod 321 pushes the switch 63.

[0041] How this application's structure works:

[0042] First, before the liquid-cooled energy storage PACK integrated lower enclosure starts working, the initial position of the locking rod is locked in the positioning hole, thus ensuring the sealing plate is stably connected to the outside of the heat dissipation holes and the entire enclosure body achieves a sealing effect. When the liquid-cooled energy storage PACK integrated lower enclosure starts working, the internal temperature of the enclosure body gradually rises. Hot air enters the pressure chamber through the air inlet, increasing the internal pressure. This increased pressure causes the sliding plate to move inside the pressure chamber. The movement of the sliding plate drives the push rod, which in turn pushes the slider, causing the slider to move its bottom connecting rod within the moving groove. Since the bottom of the connecting rod is fixedly connected to the top of the sealing plate, the sealing plate moves under the action of the connecting rod, opening the heat dissipation holes on the side wall of the enclosure body. The high-temperature heat inside the enclosure body is then discharged through the opened heat dissipation holes, thus achieving heat dissipation for the interior of the enclosure body. When the temperature inside the housing returns to normal, the sliding plate, under the action of the second return spring, drives the push rod back to its initial position, which in turn causes the slider, under the action of the first return spring, to return the sealing plate to the outside of the heat dissipation hole and the locking rod to lock into the positioning hole again.

[0043] When the slider slides on the top of the connecting plate, it can drive the pressing rod to move. The movement of the pressing rod pushes the button of the switch on the outside of the power box, thereby starting the motor of the power box. At this time, the motor will drive the fan blades at the bottom of the shaft to rotate. The rotation of the fan blades generates wind, which will accelerate the air circulation speed outside the heat dissipation holes, thereby allowing the high temperature heat inside the box to be quickly discharged to the outside of the box.

[0044] The structure of this application can be flexibly adapted to various specifications and models of energy storage PACK modules, making it more versatile and easy to apply in different energy storage project scenarios. It reduces customization costs and has an easily accessible inspection port and a reserved maintenance channel for the liquid cooling system, making subsequent operations such as inspection, repair, and replacement of liquid cooling pipes and energy storage components more convenient.

[0045] This application, by incorporating heat dissipation holes, a heat dissipation mechanism, and a fan mechanism on the side wall of the enclosure body, and installing a pressure box adapted to the heat dissipation mechanism inside the enclosure body, can promptly expel the high-temperature heat generated inside the enclosure body during operation, effectively cooling the internal components and ensuring the normal and stable operation of the energy storage system. This application features a simple structure, high practicality and economy, and can be manufactured and used as a general-purpose product.
