Description

Technical Field

[0001] This utility model relates to the technical field of battery compartment structure for integrated charging and storage piles, and in particular to a heat dissipation and pressure relief structure for battery compartments for integrated charging and storage piles. Background Technology

[0002] With the rapid development of society and the widespread application of emerging energy sources such as solar and wind power, technologies for storing and conveniently using these energy sources are also developing. Energy storage batteries have become a major technology for energy storage in recent years due to their high energy utilization rate, long service life, good high-power load capacity, light weight, and greater convenience and environmental friendliness compared to other energy storage methods. Some existing new energy vehicles require charging using energy storage batteries. As the charging power of new energy vehicles increases, integrated charging and storage piles are commonly used to address the issue of high-power charging. These integrated charging and storage piles are a new type of charging equipment that integrates energy storage and charging functions. They not only enable fast charging of electric vehicles but also store excess energy for future use. Compared to traditional charging piles, integrated charging and storage piles have higher energy utilization and lower energy waste.

[0003] Since integrated charging and storage stations are generally installed outdoors, the battery compartment is usually located in a sealed environment to improve the lifespan of the batteries inside. Therefore, its heat dissipation performance is often not very good. However, when charging vehicles and other equipment, the discharge power of the battery cells is relatively large, resulting in a large amount of heat generation. Therefore, the battery compartment of the integrated charging and storage station needs to have a good heat dissipation structure. In the event of an accident such as a fire, it should be able to quickly release pressure to prevent explosion and extinguish the fire, thereby improving the safety of the integrated charging and storage station.

[0004] Therefore, based on customer feedback regarding the shortcomings of the existing structure, the inventors made further improvements to overcome the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heat dissipation and pressure relief structure for the integrated charging and storage battery compartment that has good heat dissipation performance, can effectively relieve pressure and prevent explosions, and avoids safety hazards.

[0006] The purpose of this utility model is achieved through the following technical solution: a heat dissipation and pressure relief structure for a battery compartment of an integrated charging and storage pile, the structure of which includes a compartment body, a heat dissipation zone, and a cooling mechanism.

[0007] The interior of the compartment is arranged with multiple heat dissipation zones from top to bottom, and each heat dissipation zone is adapted to insert a battery box;

[0008] The cooling mechanism is installed on the front wall of the compartment, which is a door. The front end of the multiple heat dissipation areas is provided with an air inlet A, which is opposite to the air inlet B of the cooling mechanism. Each of the multiple heat dissipation areas is provided with an air hole, which is connected to a heat dissipation pipe. The air outlet A at the end of the heat dissipation pipe is opposite to the air outlet B of the cooling mechanism.

[0009] When the door is closed, a cold air cooling channel is formed inside the chamber; when the door is opened, the cold air cooling channel is cut off.

[0010] After inserting multiple battery boxes into the heat dissipation area of ​​the compartment in sequence, close the switch door, connect air inlet B with air inlet A, and connect air outlet A with air outlet B. Start the cooling mechanism, and the cooling medium enters the heat dissipation area from air inlet B through air inlet A to cool the batteries in the battery boxes. Then, it passes through the air vents and heat dissipation pipes from air outlet A to air outlet B and returns to the cooling mechanism to achieve circulating cooling. When the switch door is opened, the circulating cooling stops and the circulation route is closed.

[0011] As a preferred technical solution of this application, the cooling mechanism is a wall-mounted air conditioner or other equipment capable of cooling the air supply.

[0012] As a preferred technical solution of this application, the air conditioner is fixedly connected to the door of the cabin. The air conditioner is divided into an upper part and a lower part. The upper part of the air conditioner has an air outlet B and the lower part has an air inlet B.

[0013] As a preferred technical solution of this application, the heat dissipation area includes a mounting panel, in which a battery box is adapted to be inserted, and the rear panel of the mounting panel is provided with a vent, which is connected to a heat dissipation pipe and a sealing ring and a positioning pin are installed on the outside of the vent.

[0014] As a preferred technical solution of this application, an air inlet space is provided between the battery boxes arranged from top to bottom. The cold air dissipates heat from the batteries in the battery boxes in the air inlet space, and after carrying away the heat from the batteries, it is sent to the air outlet B through the heat dissipation channel.

[0015] As a preferred technical solution of this application, a pressure relief window is provided on the rear wall of the compartment. The pressure relief window is connected to a pressure relief pipe and a heat dissipation pipe. When the air pressure inside the battery box increases to a certain value, the pressure relief window opens and releases pressure.

[0016] As a preferred technical solution of this application, the battery box is equipped with a cooling fan. When cold air enters the compartment, the cooling fan is activated to draw the cold air into the battery box in the heat dissipation area.

[0017] As a preferred technical solution of this application, the battery box is also equipped with a fire extinguishing structure, and the fire extinguishing mechanism is an aerosol fire extinguisher. When a fire breaks out inside the box, the fire extinguishing mechanism is activated to release fire extinguishing gas to extinguish the fire.

[0018] This utility model has the following advantages:

[0019] (1) It has relatively good heat dissipation performance;

[0020] Because battery charging power is relatively high, and current integrated charging and storage piles are generally enclosed spaces, batteries are more prone to overheating in such environments, necessitating the installation of devices with excellent heat dissipation capabilities. This solution designs a heat dissipation structure for integrated charging and storage piles. By setting up a heat dissipation area and heat dissipation pipes within the battery compartment, which are connected to a door structure with a wall-mounted air conditioner, when the door is closed, the air conditioner's inlet and outlet align with the inlet and outlet of the heat dissipation area within the battery compartment, thus forming an air conditioner-battery cooling structure. When the door is open, the aligned inlet and outlet are disconnected, allowing the battery compartment to effectively dissipate heat while charging the vehicle. Furthermore, the system can control the on / off state of the heat dissipation system to avoid wasting cooling resources.

[0021] (2) It can effectively relieve pressure and prevent explosions, avoiding potential safety hazards;

[0022] In the event of a fire inside the sealed battery compartment, there is no suitable fireproof and explosion-proof pressure relief structure, posing a significant safety hazard. This solution adds a pressure relief pipe to the heat dissipation pipe, with a pressure relief window connected to the outside of the pipe. The pressure relief window is located on the compartment and is controlled by a voltage switch. When the pressure difference between the inside and outside of the compartment is too large, the pressure relief window opens to balance the internal and external pressure, thus providing pressure relief and explosion protection.

Therefore, they should not be construed as limitations on this utility model.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] Therefore, based on the above issues, please refer to Figure 1 This utility model proposes a heat dissipation and pressure relief structure for the battery compartment of an integrated charging and storage pile to solve the problem.

[0038] (Example)

[0039] See Figures 1-10 The proposed implementation scheme provides a heat dissipation and pressure relief structure for an integrated charging and storage pile battery compartment, which includes a compartment body 1, a heat dissipation zone 2, and a cooling mechanism.

[0040] Among them, see Figure 2 The chamber 1 is provided with multiple heat dissipation zones 2, which are arranged from top to bottom. Each heat dissipation zone 2 has an air inlet A3 at its front end and an air vent at its rear end. The air inlet A3 at the front end of the heat dissipation zone 2 is connected to the air inlet A4 of the cooling mechanism, and the air vents arranged from top to bottom are connected to a heat dissipation pipe 7. The heat dissipation pipe 7 is wound around the cooling mechanism inside the chamber 1, and the air outlet A5 at the rear end of the heat dissipation pipe 7 is connected to the air outlet B6 of the cooling mechanism.

[0041] Among them, see Figures 1-2 The cooling mechanism is a wall-mounted air conditioner 8. The air conditioner 8 can release cold air into the compartment 1 and cool the battery in the heat dissipation area 2 through the cold air. The upper part of the air conditioner 8 is provided with an air outlet B6 that passes through the switch door on the front wall of the compartment 1, and the air outlet B6 is connected to the tail end of the heat dissipation pipe 7 in the compartment 1. The lower part of the air conditioner 8 is provided with an air inlet A4, which also passes through the switch door on the front wall of the compartment 1 and is connected to the air inlet A3 at the front end of the heat dissipation area 2 in the compartment 1.

[0042] When the door of compartment 1 is closed, the air inlet A4 of air conditioner 8 is connected to the air inlet A3 of heat dissipation area 2. When air conditioner 8 is turned on, cold air enters heat dissipation area 2 from air inlet A4 of air conditioner 8 to dissipate heat from the battery in the charging state. The cold air carries heat through the air vent at the end of heat dissipation area 2 and through the heat dissipation channel to air outlet A5. At the same time, since air outlet B6 is connected to air outlet A5 when the door is closed, the airflow returns to air conditioner 8, realizing the circulating cooling in battery compartment. When the door is opened, the air inlets and outlets are no longer connected, and the cooling circulation route is cut off.

[0043] Current integrated charging and storage piles for batteries lack adequate internal heat dissipation structures. However, when charging vehicles, the battery compartment is in a sealed environment, and the battery generates significant heat during charging, leading to potential battery problems or malfunctions and a shortened lifespan. Therefore, a reasonable and user-friendly heat dissipation structure is needed within the battery compartment of the integrated charging and storage pile to address these issues. This solution designs a heat dissipation and pressure relief structure for the battery compartment of an integrated charging and storage pile. By installing a door structure with a wall-mounted air conditioner 8 on the compartment 1, the air conditioner 8 and the heat dissipation area 2 inside the compartment 1 form a heat dissipation and cooling circulation loop. When the door is closed, cold air is blown out from the air conditioner 8 and enters the heat dissipation area 2 inside the compartment 1, carrying away the heat from the battery and returning to the air conditioner 8 through the heat dissipation pipe 7, thus achieving heat dissipation circulation. When the door is opened, the cold air cooling circulation loop formed by the air conditioner 8 and the interior of the compartment 1 is cut off, facilitating easy replacement of the battery compartment and maintenance. This structure also provides excellent heat dissipation capabilities.

[0044] In this embodiment, see Figure 1 and Figure 2For compartment 1, compartment 1 is a rectangular cabinet structure. Inside compartment 1, there are four heat dissipation zones 2, which are arranged in a row from top to bottom. Each heat dissipation zone 2 is equipped with a mounting panel. The battery box is inserted into the mounting panel. The rear panel of the mounting panel has vents. After the battery box is inserted into the heat dissipation zone 2, there is a certain space between the battery box and the vents to avoid obstructing the flow of cold air. The outer ring of the vents is equipped with a sealing ring and a positioning pin, which are adapted to connect and pass through the interface of the heat dissipation pipe 7. A total of four battery boxes are inserted into the four heat dissipation zones 2 from top to bottom. There is an air intake space between the four battery boxes arranged in a row. The air conditioner 8 sends cold air into the heat dissipation zone 2 from the air inlet A4 and through the air inlet A3. In the air intake space, the air dissipates heat from the battery in the battery box, carrying away the heat and preventing the battery from overheating and swelling, which would affect the battery life.

[0045] Furthermore, each battery compartment is equipped with a cooling fan. When the air conditioner 8 is turned on to allow cold air to enter the compartment 1, the cooling fan is activated. The cooling fan rotates to draw the cold air into the battery compartment in the heat dissipation area 2. The cooling fan design enables the cold air circulation in the compartment 1 to be stable and orderly.

[0046] It should be noted that the wall-mounted air conditioner 8 is existing technology. It has less noise, saves space and is easy to install. The air conditioner 8 is installed on the switch door. After pushing the battery box into the compartment and closing the compartment door, the mechanism of constructing pipeline - closing the switch door to allow the circulation pipeline to flow smoothly - opening the switch door to cut off the circulation pipeline can be achieved.

[0047] It should be noted that after the door is closed, the battery compartment 1 is a sealed space. The air exchange between the air conditioner 8 and the heat dissipation pipes of the heat dissipation area 2 inside the compartment 1 is carried out to dissipate heat from the battery. The sealed structure of the compartment 1 can prevent external dust and debris from entering the compartment 1 and contaminating the battery in the battery box, thus reducing its service life.

[0048] In this embodiment, see Figure 2 and Figures 4-7 For the heat dissipation pipe 7, the main body of the heat dissipation pipe 7 is an L-shaped long pipe. The lower part of the heat dissipation pipe 7 has four interfaces, which are arranged in a row from top to bottom. The four interfaces are matched and installed with four air vents, which correspond to the four battery boxes. The upper part of the heat dissipation pipe 7 wraps around to the front wall of the compartment 1, and an air outlet A5 is set at the upper end. The air outlet A5 is directly opposite the air outlet B6 of the air conditioner 8. The heat dissipation pipe 7 is set in the compartment 1 mainly to transport the air carrying the heat of the battery boxes back to the air conditioner 8, so that the heat dissipation and cooling circulation line of the battery is realized.

[0049] Furthermore, see Figure 2 and Figures 6-7A pressure relief pipe 9 is installed at the corner of the ventilation duct, and the pressure relief pipe 9 is connected to the heat dissipation pipe 7. The end of the pressure relief pipe 9 is directly opposite the rear wall of the compartment 1 and is connected to a pressure relief window 10. The pressure relief window 10 is located on the upper part of the rear wall of the compartment 1. When the air conditioner 8 is turned on to deliver cold air into the compartment 1, the pressure relief window 10 is closed. At this time, the heat dissipation area 2 and the heat dissipation channel form a heat dissipation and cooling circulation line with the air conditioner 8. When the charging and storage pile releases an accident, the internal air pressure of the battery increases. At this time, the pressure difference between the inside and outside of the pressure relief window 10 (i.e., the pressure inside the compartment 1 and the external pressure) connected to the battery box through the heat dissipation pipe 7 and the pressure relief pipe 9 is very large. When the pressure increases to a certain value, the control voltage of the pressure relief window 10 is activated, and the pressure relief window 10 is opened immediately. At this time, a pressure relief line is formed - the pressure is relieved from the battery box into the heat dissipation pipe 7 - through the heat dissipation pipe 7 to the pressure relief pipe 9 to the pressure relief window 10 for pressure relief - until the pressure inside the compartment 1 is the same as the external pressure.

[0050] It should be noted that a fire extinguishing mechanism is installed inside the battery box. This fire extinguishing mechanism is an aerosol fire extinguisher. When a fire occurs inside the charging compartment of the integrated charging and storage pile in this solution, the aerosol fire extinguisher releases extinguishing gas to treat the source. At the same time, the air pressure inside the battery box rises due to the extinguishing gas, which causes the pressure relief line to open and the pressure relief window 10 to release pressure.

[0051] Furthermore, see Figure 10 Since the pressure relief window 10 serves as a connection between the outside and the inside of the battery compartment, and is connected to the pressure relief pipe 9 through the heat dissipation pipe 7, when the battery compartment catches fire again or the fire becomes uncontrollable, the batteries inside the battery compartment can no longer be used due to the fire. Therefore, the pressure relief window 10 is opened and water is directly injected into the battery compartment for fire fighting. The water is injected directly into the battery box from the pressure relief window 10-pressure relief pipe 9-heat dissipation pipe 7, immersing the burning batteries in the water, which plays the role of submersion fire fighting.

[0052] After installing the battery box into the battery compartment 1, close the door of compartment 1. At this time, the air inlet A4 of the air conditioner 8 is connected to the air inlet A3 of compartment 1, and the air outlet B6 of the air conditioner 8 is connected to the air outlet A5 of the heat dissipation pipe 7. Turn on the air conditioner 8 to blow out cold air from the air inlet A4 through the air inlet A3 into the heat dissipation area 2 to cool the battery in the battery box. With the action of the cooling fan, the cold air carries the heat on the surface of the battery through the air hole at the end of the heat dissipation area 2 into the heat dissipation channel, and then through the heat dissipation channel to the air outlet A5 and back into the air conditioner 8. At this time, open the door to cut off the heat dissipation route, which facilitates the replacement of the battery box and the control of the heat dissipation function of compartment 1, making the heat dissipation of the battery compartment continuous and controllable. When the fire extinguisher releases extinguishing gas due to an accident such as a fire in compartment 1, the gas pressure in the battery box increases. At this time, the pressure relief window 10 is opened, and the pressure relief pipe 9 and the heat dissipation pipe 7 are used to relieve the pressure in the battery box to prevent the battery from swelling, which would shorten the battery life.

[0053] Existing integrated charging and storage piles for car charging are generally located outdoors and are typically enclosed spaces. During charging, the high charging power of the battery makes it prone to overheating in the confined environment, leading to bulging and a shortened lifespan. Existing integrated charging and storage piles lack effective heat dissipation structures, are inconvenient to cool, and have complex structures. Furthermore, in the event of a fire within the enclosed compartment 1, there are no suitable fireproof, explosion-proof, and pressure relief structures, posing a significant safety hazard. This solution designs a battery compartment for an integrated charging and storage pile with excellent heat dissipation and pressure relief structures, effectively preventing battery overheating, bulging, and explosion. This is achieved by incorporating a heat dissipation zone 2 and heat dissipation pipes 7 within the battery compartment, along with a wall-mounted air conditioner 8. The door opening and closing mechanism works in tandem. When the door is closed, the inlet and outlet of the air conditioner 8 connect with the inlet and outlet of the heat dissipation area 2 of the compartment 1, thus forming a cooling and heat dissipation structure of air conditioner 8 and compartment 1. When the door is opened, the connecting inlet and outlet are disconnected, thereby effectively and precisely controlling the heat dissipation function of compartment 1 and avoiding waste. At the same time, a pressure relief pipe 9 is also connected to the heat dissipation pipe 7 inside compartment 1. The pressure relief pipe 9 is connected to the pressure relief window 10. When the pressure difference between the inside and outside of compartment 1 is too large, the pressure relief window 10 opens to balance the internal and external pressure difference and prevent the battery from exploding. In addition, in the event of a battery fire, water can be injected into the interior through the pressure relief window 10 and the pressure relief pipe 9 to achieve immersion fire protection and prevent fire accidents.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
