Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a battery cover with a heat dissipation structure. Background Technology

[0002] In today's era of rapid development in communication technology, communication equipment has become the core carrier of social information transmission and interaction. Its stable operation directly depends on continuous and reliable power supply, and batteries, as key energy storage and power supply components of communication equipment, play an indispensable role. Whether it's the backup power supply system of base stations and data centers, or the built-in power supply module of portable communication terminals and emergency communication equipment, batteries need to be in working condition for extended periods to provide energy for signal processing, data transmission, and functional operation of communication equipment. Especially in scenarios where technologies such as 5G communication and the Internet of Things are widely used, the data processing volume and energy consumption of communication equipment have increased significantly, placing higher demands on the power supply stability, battery life, and operational safety of batteries. The working state of the battery is closely linked to the overall performance and operational reliability of the communication equipment. Once the battery malfunctions or its performance degrades, it will directly affect the normal operation of the communication equipment and may even lead to serious problems such as communication interruption.

[0003] When using batteries, we found that most batteries lack targeted and efficient heat dissipation structures. They rely solely on the natural heat dissipation of the casing itself, which cannot quickly dissipate the large amount of heat generated during battery operation. This causes heat to accumulate inside and around the battery. When the temperature exceeds the safety threshold, it will not only accelerate battery aging and shorten battery life, but may also cause safety hazards such as battery bulging, leakage, or even fire, thereby affecting the stable power supply of communication equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a battery cover with a heat dissipation structure, including a bottom shell, a battery assembly installed inside the bottom shell via a connecting frame, a top cover provided on the upper part of the bottom shell, the front side of the top cover being connected to the upper part of an end cover, an end cover provided on the front part of the bottom shell, a power connection component provided on the front part of the end cover, a controller provided on the rear part of the end cover, a heat dissipation mechanism provided in the middle of the top cover, the lower part of the heat dissipation mechanism being connected to the battery assembly, and the controller being electrically connected to the battery assembly, the power connection component, and the heat dissipation mechanism; The heat dissipation mechanism includes a heat-conducting component, a heat insulation chamber, multiple semiconductor wafers, heat dissipation fins, multiple heat dissipation fans, and a heat dissipation cover. The lower part of the heat-conducting component is located in the middle of the battery assembly. The outer periphery of the semiconductor wafers is installed in the lower part of the heat insulation chamber. The lower cooling side of the semiconductor wafers is connected to the heat-conducting component via thermal grease. The heat dissipation fins are installed inside the heat insulation chamber. The lower part of the heat dissipation fins is connected to the upper heat dissipation side of the semiconductor wafers via thermal grease. The heat insulation chamber is installed on the inner bottom wall of the upper cover. The lower part of the heat dissipation fans is installed on the upper part of the heat dissipation fins. The heat dissipation cover is installed on the upper part of the upper cover and covers the outer periphery of the heat dissipation fans.

[0007] Preferably, the end cap is provided with connecting wing plates on the left and right sides.

[0008] Preferably, a filter screen is installed on the inner wall of the heat dissipation cover.

[0010] Preferably, thermal grease is used to fill the space between the heat-conducting plate and the heat-conducting sheet.

[0011] Compared with the prior art, this utility model has the following beneficial effects: Through the synergistic effect of the heat-conducting components, semiconductor plates, heat dissipation fins and heat dissipation fan, and with the help of the high-efficiency heat conduction characteristics of thermal grease and the heat insulation chamber's anti-heat backflow design, the heat generated by the battery module during operation can be quickly absorbed and discharged. With the intelligent linkage of temperature sensor and controller, the battery temperature can be monitored in real time. When the temperature exceeds the threshold, heat dissipation will be automatically started and automatically stopped when the temperature drops to a safe range. This effectively avoids battery damage due to high temperature, significantly extends the service life of the battery module, reduces unnecessary energy consumption, and ensures the stability of power supply.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-4 As shown, a battery cover with a heat dissipation structure includes a bottom shell 1, a battery assembly 8 installed inside the bottom shell 1 via a connecting bracket 9, a top cover 2 on the upper part of the bottom shell 1, the front side of the top cover 2 being connected to the upper part of an end cover 4, an end cover 4 on the front part of the bottom shell 1, a power connection component 5 on the front part of the end cover 4, a controller 10 on the rear part of the end cover 4, a heat dissipation mechanism 3 in the middle of the top cover 2, the lower part of the heat dissipation mechanism 3 being connected to the battery assembly 8, and the controller 10 being electrically connected to the battery assembly 8, the power connection component 5, and the heat dissipation mechanism 3; a temperature sensor is installed on the upper part of the bottom shell 1 or the lower part of the top cover 2, and the temperature sensor is connected to the controller 10; the top cover 2 is made of heat-insulating material to prevent the dissipated heat from being transferred to the internal battery assembly 8 through the top cover 2.

[0016] The heat dissipation mechanism 3 includes a heat-conducting component 301, a heat insulation chamber 302, multiple semiconductor wafers 303, heat dissipation fins 304, multiple cooling fans 305, and a heat dissipation cover 306. The lower part of the heat-conducting component 301 is located in the middle of the battery assembly 8. The outer periphery of the semiconductor wafers 303 is installed in the lower part of the heat insulation chamber 302. The lower cooling side of the semiconductor wafers 303 is connected to the heat-conducting component 301 through thermal grease. The heat dissipation fins 304 are installed inside the heat insulation chamber 302. The lower part of the heat dissipation fins 304 is connected to the upper heat dissipation side of the semiconductor wafers 303 through thermal grease. The heat insulation chamber 302 is installed on the inner bottom wall of the upper cover 2. The lower part of the cooling fans 305 is installed on the upper part of the heat dissipation fins 304. The heat dissipation cover 306 is installed on the upper part of the upper cover 2 and covers the outer periphery of the cooling fans 305. The heat insulation chamber 302 is installed on the inner bottom wall of the upper cover 2. The upper and lower sides of the semiconductor wafers 303 are isolated by the heat insulation chamber 302 to prevent heat from flowing back.

[0017] Handles 7 are provided on the left and right sides of the end cap 4, which facilitates the picking and carrying of the device.

[0018] Connecting wing plates 6 are provided on the left and right sides of the end cap 4. The device can be connected and fixed to other equipment through the connecting wing plates 6, which facilitates operation.

[0019] A filter screen is installed on the inner wall of the heat sink cover 306 to prevent dust from adhering to the surface of the heat sink fins 304, thereby maintaining the efficient heat dissipation effect of the heat sink fins 304.

[0020] The heat-conducting assembly 301 includes a heat-conducting plate 3011, a fixing plate 3012, and a heat-conducting sheet 3013. The upper side of the heat-conducting plate 3011 is installed on the lower part of the semiconductor sheet 303 with thermal grease. The lower part of the heat-conducting plate 3011 is installed on the upper part of the fixing plate 3012. The upper end of the heat-conducting sheet 3013 is disposed between the heat-conducting plate 3011 and the fixing plate 3012. The heat-conducting sheet 3013 is inserted into the gap of the battery assembly 8, and heat exchange is completed between the heat-conducting sheet 3013 and the battery assembly 8, thereby reducing the temperature of the battery assembly 8, protecting the battery assembly 8, and extending the service life of the battery assembly 8.

[0021] Thermal grease is filled between the heat-conducting plate 3011 and the heat-conducting sheet 3013. The thermal grease allows the heat-conducting plate 3011 and the heat-conducting sheet 3013 to make full contact on the opposite side, thereby conducting heat. The heat-conducting sheet 3013 is inserted into the gap of the battery module 8, and heat exchange is completed between the heat-conducting sheet 3013 and the battery module 8, thereby reducing the temperature of the battery module 8, protecting the battery module 8, and extending the service life of the battery module 8.

[0022] Working principle: A temperature sensor monitors the ambient temperature of the battery module 8 in real time and transmits the temperature data to the controller 10. The controller 10 is electrically connected to the battery module 8, the power connection component 5, and the heat dissipation mechanism 3 to provide power and control for the entire system. When the temperature sensor detects that the temperature of the battery module 8 exceeds a preset safety threshold, the controller 10 immediately activates the heat dissipation mechanism 3. The heat dissipation mechanism 3 starts operating, and the heat-conducting plate 3013 inserted into the gap of the battery module 8 quickly exchanges heat with the battery module 8. The absorbed heat is transferred to the heat-conducting plate 3011 via thermal grease. The heat-conducting plate 3011 then transfers the heat to the lower part of the semiconductor plate 303. The semiconductor plate 303 transfers the heat to the heat dissipation fins 304 via thermal grease through the Peltier effect. The controller 10 simultaneously drives the cooling fan 305 installed on the upper part of the heat dissipation fins 304 to start. The cooling fan 305 generates airflow to carry away the heat from the surface of the heat dissipation fins 304. The heat is discharged from the heat dissipation cover 306, and the filter screen on the inner wall of the heat dissipation cover 306 can prevent dust from adhering to the surface of the heat dissipation fins 304, ensuring heat dissipation efficiency. In addition, the handles 7 on both sides of the end cap 4 facilitate the handling of the device, and the connecting wing plate 6 can connect and fix the device to other equipment. When the temperature sensor detects that the temperature of the battery pack 8 has dropped below the safety threshold, the controller 10 cuts off the power supply to the heat dissipation mechanism 3, stops the operation of the semiconductor chip 303 and the cooling fan 305, and completes one heat dissipation cycle, which not only ensures the safe operation of the battery pack 8 and extends its service life, but also avoids energy waste.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
