Description
Technical Field
[0001] This utility model belongs to the technical field of battery swapping cabinets, and in particular relates to a fireproof battery swapping cabinet heat dissipation mechanism. Background Technology
[0002] Electric vehicles are typically equipped with stationary rechargeable batteries. For extended periods of use, the downtime caused by charging is inconvenient, such as in the food delivery industry where continuous use of electric vehicles is required. To eliminate this waiting time, removable rechargeable new energy batteries are ideal. Designated charging stations with multiple battery compartments are also necessary. Users can log in by scanning a code and then designate a specific battery for replacement, swapping depleted and fully charged batteries to achieve rapid full charging.
[0003] Battery swapping cabinets are typically placed outdoors. To prevent rainwater intrusion, the cabinets need to be airtight, which can lead to poor heat dissipation. Furthermore, since the cabinets are constantly charging, both the charger and the battery generate heat. If this heat isn't dissipated promptly, high temperatures can easily cause a fire. While existing battery swapping cabinets have fire extinguishing functions to reduce the fire risk, high temperatures still cause electrical components to age prematurely. Although multiple fans are installed in various locations within the cabinet, these fans are positioned at multiple points within the cabinet itself. The internal structure of the cabinet is complex, with various components tightly packed together, resulting in poor airflow. The airflow generated by the fans is insufficient for effectively exchanging heat with the battery compartment, leading to inadequate cooling. Utility Model Content
[0004] The purpose of this utility model is to provide a fireproof battery swapping cabinet heat dissipation mechanism. Combining the structural characteristics of the battery swapping cabinet, an air guide channel is added to realize the multi-purpose use of the air guide channel, so that the fan can specifically heat the battery compartment, improve airflow, and improve heat dissipation efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A fireproof battery swapping cabinet heat dissipation mechanism includes a cabinet body. Inside the cabinet body, the upper layer is an electrical control compartment, the middle layer has multiple battery compartments arranged and installed, and the bottom layer has a water tank. Each battery compartment has an open side and a door corresponding to the front side of the cabinet body. The rear side of the cabinet body has an openable door. A fire extinguishing nozzle is installed on the top of each battery compartment. The battery compartment is installed at an angle inside the cabinet, with the opening side of the battery compartment being the high side and the rear cover position being the low side. A drain hole is provided at the bottom of the battery compartment corresponding to the rear cover. A first busbar is installed at the rear side of the cabinet. The first busbar is installed vertically, with a cross-section of U-shape and a first busbar groove. All the drain holes are connected to the first busbar groove. The battery compartment has a first vent at the rear cover position, and the first vent corresponds to the return groove. The lower end of the first manifold is connected to the water tank, and the upper end is an open structure. The cabinet door is provided with a louvered vent corresponding to the position of the upper end of the first manifold, and a first fan is installed thereon.
[0006] Furthermore, a front frame is installed on the front side of the cabinet, and the frame has an installation port for supporting and fixing the battery compartment. A second busbar is provided at the rear cover of the battery compartment, and the second busbar is fixed to the first busbar.
[0007] The second busbar is horizontally positioned and has an upward-facing second busbar channel. The second busbar has a long, narrow structure with a U-shaped cross-section. Drainage holes are located at the bottom corners of the battery compartment's rear cover, arranged in a row along the bottom rear edge of the battery compartment, and corresponding to the second busbar channels. All second busbar channels are connected to the first busbar channel. The second busbar is fixed to the first busbar via a mounting plate. The second busbar is equipped with a guide pipe for connecting the second busbar channel to the first busbar channel.
[0008] Furthermore, a second vent is provided on the side wall of the battery compartment, and a second fan is installed thereon.
[0009] The present invention has the following advantages: the rear cover of the battery compartment not only has a drainage hole, but also a first vent. The first vent is a mesh vent formed by punching holes in the rear cover of the battery compartment. The first vent faces the first confluence channel, which can quickly introduce the heat inside the battery compartment into the first confluence channel. According to the principle of hot air rising, the hot air flow is concentrated in the first confluence channel and flows upward to the upper slot. The cabinet door has a first fan at the upper opening of the return channel to further exhaust the hot air.
[0010] The first manifold not only allows for the centralized recycling of fire-extinguishing water, but also extracts heat from each battery compartment. The airflow channel formed by the first manifold facilitates unidirectional airflow with high targeting, concentrating the negative pressure generated by the first fan on each battery compartment for better heat dissipation.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] like Figures 1-5 As shown: A fireproof battery swapping cabinet heat dissipation mechanism includes a cabinet body 1. Inside the cabinet body 1, the upper layer is an electrical control compartment 11, the middle layer contains multiple battery compartments 3, and the bottom layer contains a water tank 12. Each battery compartment 3 has an open side and a door corresponding to the front of the cabinet body 1. The rear of the cabinet body 1 has an openable door 2. A fire extinguishing nozzle 30 is installed on the top of each battery compartment 3. The mechanism is characterized by being housed within a fireproof battery swapping cabinet. The bottom of the cabinet contains a water tank for storing water for fire extinguishing. The water tank is powered by a micro diaphragm pump and connected to the nozzle assemblies on the top of each battery compartment via water pipes. The cabinet also includes a control system and a smoke alarm. When a high-temperature fire occurs inside the cabinet, smoke is emitted first and detected by the smoke alarm. The smoke alarm then activates the nozzles to spray and extinguish the fire in the battery compartments before it escalates into an open flame, preventing the formation of an open flame.
[0020] The battery compartment 3 is installed at an angle inside the cabinet 1. The opening side of the battery compartment 3 is the high side, and the rear cover position is the low side. A drain hole 31 is provided at the bottom of the battery compartment 3 corresponding to the rear cover. A first busbar 4 is installed at the rear side inside the cabinet 1. The first busbar 4 is installed vertically and has a cross-section of C-shape. It has a first busbar groove, and the drain hole 31 is connected to the first busbar groove. A first vent 32 is provided at the rear cover position corresponding to the battery compartment 3, and the first vent 32 corresponds to the return groove. The lower end of the first manifold connects to the water tank 12, and the upper end of the manifold is an open structure. The cabinet door 2 is provided with a louvered vent 21 corresponding to the position of the upper end of the first manifold, and a first fan 22 is installed thereon. The first manifold has a first manifold facing the rear cover side of the battery compartment. The first manifold is located in the center and is vertically set. The battery compartment is installed at an angle, with the front higher than the back, which helps to collect the sprayed water at the rear end inside the battery compartment and guide it into the first manifold through the drain hole. Finally, it flows back to the water tank, reusing water resources and preventing water from staying in the battery compartment for a long time, which could cause damage to electrical components due to soaking.
[0021] The rear cover of the battery compartment not only has a drainage hole, but also a first vent. The first vent is a mesh vent formed by punching holes in the rear cover of the battery compartment. The first vent faces the first confluence channel, which can quickly introduce the heat inside the battery compartment into the first confluence channel. According to the principle of hot air rising, the hot air flow is concentrated in the first confluence channel and flows upward to the upper slot. The cabinet door has a first fan at the upper opening of the return channel to further exhaust the hot air.
[0022] The first manifold not only allows for the centralized recycling of fire-extinguishing water, but also extracts heat from each battery compartment. The airflow channel formed by the first manifold facilitates unidirectional airflow with high targeting, concentrating the negative pressure generated by the first fan on each battery compartment for better heat dissipation.
[0023] like Figures 4-5 As shown: A front-mounted frame 5 is installed on the front side of the cabinet 1. The frame 5 has an installation port for supporting and fixing the battery compartment 3. Second busbars 6 are installed at the rear cover position of the battery compartment 3, and each second busbar 6 is fixed to a first busbar 4. The frame is a sheet metal structure installed on the front side of the cabinet. The frame acts as a supporting component for the battery compartment. The opening side of the battery compartment can extend through the installation port to form a door corresponding to the front side of the cabinet, used for inserting or removing batteries. The second busbar 6 is horizontally positioned and has an upward-facing second busbar channel. The second busbar 6 is a long strip structure with a U-shaped cross-section. Drainage holes 31 are opened at the bottom corners of the rear cover of the battery compartment 3, arranged in a row along the bottom rear edge of the battery compartment 3, and corresponding to the second busbar channel. The second busbar channels are all connected to the first busbar channel. To ensure sufficient drainage inside the battery compartment, drainage holes are arranged in a row at the bottom rear side of the battery compartment to improve drainage efficiency. After being uniformly collected by the second busbar channel, the water is centrally channeled into the first busbar channel.
[0024] The second manifold 6 is fixed to the first manifold 4 by the mounting plate 61. The second manifold 6 is provided with a guide pipe 62 for connecting the second manifold to the first manifold.
[0025] like Figure 5As shown: A second vent is provided on the side wall of the battery compartment 3, and a second fan 33 is installed thereon. The second vent is similar in structure to the first vent, but in a different location. One is located on the rear cover of the battery compartment, and the other is located on the side wall cover of the battery compartment. The second fan blows air into the battery compartment, and then the airflow is introduced through the first vent, which helps to form a unidirectional airflow in the battery compartment and improves heat dissipation efficiency.
[0026] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
