Description

Technical Field

[0001] This utility model belongs to the field of lithium battery energy storage technology, and in particular relates to a pull-out heat dissipation device for lithium battery energy storage devices. Background Technology

[0002] A heat dissipation device for lithium battery energy storage is a device or system specifically designed to manage and control the operating temperature of the battery system. Its core objective is to dissipate the heat generated by the battery cell in a timely manner through effective heat conduction, convection, or phase change mechanisms, ensuring that the battery operates within a safe and stable temperature range.

[0003] Traditional lithium battery energy storage devices typically use energy storage cabinets to store lithium batteries. The cabinets are usually equipped with multiple cooling fans installed with screws to achieve heat dissipation. However, when it is necessary to maintain the heat dissipation device later, the cooling fans are not easy to disassemble, the operation process is relatively cumbersome, and it is difficult to flexibly carry out the maintenance work of the heat dissipation device. Utility Model Content

[0004] The purpose of this invention is to provide a pull-out heat dissipation device for lithium battery energy storage devices. By setting up a heat dissipation mechanism, specifically by pulling the pull plate to move the outer baffle outward, the square base is pulled out, and at the same time, the metal heat sink and metal contact plate are pulled away from the stored lithium battery, allowing staff to perform maintenance work and making subsequent operations more convenient. At the same time, pushing the outer baffle into the energy storage cabinet can start heat dissipation. This solves the problem that traditional lithium battery energy storage devices usually use screws to install multiple cooling fans to achieve the heat dissipation effect, but when the heat dissipation device needs to be maintained later, the cooling fans are not easy to disassemble, and the operation process is relatively cumbersome.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a pull-out heat dissipation device for a lithium battery energy storage device, including an energy storage cabinet, the bottom of which is fixedly connected to a base, and further comprising:

[0007] A heat dissipation mechanism is provided on the outside of the energy storage cabinet. The heat dissipation mechanism includes an outer baffle on the side of the energy storage cabinet. A square base is fixedly connected to the side of the outer baffle facing the energy storage cabinet. Two pull plates are fixedly connected to the outside of the outer baffle. A heat dissipation fan is installed inside the outer baffle. Sliding rods are fixedly connected to both ends of the side of the outer baffle facing the energy storage cabinet.

[0008] The cooling fan is fixed to the outer baffle with screws and is used to draw heat out of the energy storage cabinet to the outside.

[0009] Furthermore, the energy storage cabinet is internally connected to several brackets, and several support plates are installed on the brackets. Storage lithium batteries are positioned and installed on the support plates. After the storage lithium batteries are positioned on the support plates, they are interconnected by wires and connected to the controller.

[0010] The support plate is used to support the stored lithium batteries, which are placed in two layers.

[0011] Furthermore, the energy storage cabinet has several square sockets and several limiting grooves on both the left and right sides, with each pair of limiting grooves having two ends of the square socket; the square sockets are adapted to the square bases, and the limiting grooves are adapted to the sliding rods.

[0012] Furthermore, a number of metal heat sinks are fixedly connected to the side of the square base away from the outer baffle, and a metal contact piece is fixedly connected to the side of the metal heat sink away from the square base. The metal contact piece contacts the surface of the stored lithium battery. The metal heat sink and the metal contact piece are integrally formed to efficiently transfer the heat of the stored lithium battery.

[0013] The metal contact piece is used to transfer heat from the stored lithium battery to the metal heat sink, and the metal heat sink is used to transfer heat to the outer baffle.

[0014] Furthermore, the square base is inserted into the energy storage cabinet through a square socket, and the slide rod is slidably connected to the energy storage cabinet through a limiting slide groove. A limiting protrusion is fixedly connected to the side of the slide rod away from the outer baffle. By pulling the pull plate to move the outer baffle outward, the square base will be pulled out, and the slide rod will slide on the limiting slide groove.

[0015] Furthermore, magnetic blocks are embedded in all four corners of the outer baffle facing the energy storage cabinet. The magnetic blocks are in contact with the surface of the energy storage cabinet and use magnetic attraction to fix the outer baffle. The sliding rod is used to support and fix the outer baffle, and the limiting protrusion is used to limit the movement of the sliding rod. When the outer baffle is pushed into the energy storage cabinet, the magnetic blocks on the outer baffle will fix the outer baffle to the energy storage cabinet by magnetic attraction after they come into contact with the surface of the energy storage cabinet.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model features a heat dissipation mechanism. Specifically, by pulling the pull plate, the outer baffle moves outward, causing the square base to be pulled out. At the same time, the metal heat sink and metal contact plate are pulled away from the stored lithium battery, allowing staff to perform maintenance work and making subsequent operations more convenient. Simultaneously, pushing the outer baffle into the energy storage cabinet enables heat dissipation.

[0018] 2. This utility model uses metal heat sinks. Specifically, after the outer baffle is pushed into the energy storage cabinet, the metal contact plate will contact the surface of the stored lithium battery. By starting the cooling fan, the heat inside the energy storage cabinet is drawn out to the outside. At the same time, the heat from the stored lithium battery is transferred to the metal contact plate, and then transferred to the outer baffle through the metal heat sink for further heat dissipation. In addition, the cooling fan can carry away the heat on the metal heat sink, thus improving the heat dissipation effect.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figures 1-5 As shown, this utility model is a pull-out heat dissipation device for a lithium battery energy storage device, including an energy storage cabinet 1, a base 11 fixedly connected to the bottom of the energy storage cabinet 1, and further including:

[0030] The heat dissipation mechanism 2 is located on the outside of the energy storage cabinet 1. The heat dissipation mechanism 2 includes an outer baffle 21 located on the side of the energy storage cabinet 1. A square base 211 is fixedly connected to the side of the outer baffle 21 facing the energy storage cabinet 1. Two pull plates 23 are fixedly connected to the outside of the outer baffle 21. A cooling fan 22 is installed inside the outer baffle 21. Sliding rods 213 are fixedly connected to both ends of the side of the outer baffle 21 facing the energy storage cabinet 1. By pulling the pull plates 23, the outer baffle 21 is moved outward, and the square base 211 is pulled out. At the same time, the metal heat sink 24 and the metal contact plate 241 are pulled away from the lithium battery 122, so that the staff can carry out maintenance work, which is more convenient for subsequent operations. At the same time, the outer baffle 21 can be pushed into the energy storage cabinet 1 to carry out heat dissipation.

[0031] The cooling fan 22 is fixed to the outer baffle 21 by screws, and the cooling fan 22 is used to draw the heat in the energy storage cabinet 1 to the outside.

[0032] The energy storage cabinet 1 has several brackets 12 fixedly connected inside, and several support plates 121 are installed on the brackets 12. A lithium battery 122 is positioned and installed on the support plate 121.

[0033] The support plate 121 is used to support the storage lithium battery 122, which is placed in two layers.

[0034] The energy storage cabinet 1 has several square sockets 13 and several limiting grooves 14 on both the left and right sides, and each pair of limiting grooves 14 is provided with the two ends of the square sockets 13.

[0035] A number of metal heat sinks 24 are fixedly connected to the side of the square base 211 away from the outer baffle 21. A metal contact piece 241 is fixedly connected to the side of the metal heat sink 24 away from the square base 211. The metal contact piece 241 is in contact with the surface of the stored lithium battery 122. After the outer baffle 21 is pushed into the energy storage cabinet 1, the metal contact piece 241 will contact the surface of the stored lithium battery 122. By starting the cooling fan 22, the heat inside the energy storage cabinet 1 is drawn out to the outside. At the same time, the heat of the stored lithium battery 122 will be transferred to the metal contact piece 241, and then transferred to the outer baffle 21 through the metal heat sink 24 for heat dissipation. The cooling fan 22 can also carry away the heat on the metal heat sink 24 to improve the heat dissipation effect.

[0036] The metal contact piece 241 is used to transfer heat from the lithium battery 122 to the metal heat sink 24, and the metal heat sink 24 is used to transfer heat to the outer baffle 21.

[0037] The square base 211 is inserted into the energy storage cabinet 1 through the square socket 13, and the slide rod 213 is slidably connected to the energy storage cabinet 1 through the limiting slide groove 14. The side of the slide rod 213 away from the outer baffle 21 is fixedly connected to the limiting protrusion 214.

[0038] Magnetic blocks 212 are embedded in the four corners of the outer baffle 21 facing the energy storage cabinet 1. The magnetic blocks 212 are in contact with the surface of the energy storage cabinet 1. The magnetic blocks 212 use magnetic attraction to fix the outer baffle 21. The slide rod 213 is used to support and fix the outer baffle 21. The limiting protrusion 214 is used to limit the movement of the slide rod 213.

[0039] One specific application of this embodiment is:

[0040] In use, the lithium battery 122 is positioned on the support plate 121 and connected to the controller via wires. Then, the outer baffle 21 is pushed into the energy storage cabinet 1, and the square base 211 enters the square socket 13. At the same time, the slide rod 213 slides within the limiting groove 14. When the magnetic block 212 on the outer baffle 21 contacts the surface of the energy storage cabinet 1, the outer baffle 21 is fixed to the energy storage cabinet 1 by magnetic attraction. At this time, the metal contact piece 241 contacts the surface of the lithium battery 122. Then, the cooling fan 22 is inserted into the outer baffle. At the center of plate 21, and fixed with screws, the heat in the energy storage cabinet 1 is drawn out to the outside by starting the cooling fan 22, which can dissipate heat from the stored lithium battery 122. At the same time, the heat from the stored lithium battery 122 is transferred to the metal contact piece 241, and then transferred to the outer baffle 21 through the metal heat sink 24 for heat dissipation. The cooling fan 22 can also carry away the heat on the metal heat sink 24, thereby dissipating heat from the metal heat sink 24 and improving the heat dissipation effect of the metal heat sink 24 and the metal contact piece 241 on the stored lithium battery 122.

[0041] When maintenance of the heat dissipation mechanism 2 is required, the outer baffle 21 is moved outward by pulling the pull plate 23, the square seat 211 is pulled out, and the slide bar 213 slides on the limiting slide groove 14. At the same time, the metal heat sink 24 and the metal contact piece 241 are pulled away from the lithium battery 122. When the limiting protrusion 214 contacts the inner wall of the energy storage cabinet 1, the outer baffle 21 is limited. At this time, the cooperation of the slide bar 213 and the limiting protrusion 214 will support the outer baffle 21, so that the staff can carry out maintenance work, which is more convenient for subsequent operations.
