Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology for new energy ships, and in particular to a heat dissipation device for lithium batteries in new energy ships. Background Technology

[0002] The heat generated by lithium batteries in new energy ships during use requires a heat dissipation system to maintain the battery's operating temperature range and ensure its safety and high efficiency. Liquid cooling systems are a common heat dissipation device for lithium batteries in new energy ships. Coolant flows through cooling pipes outside the battery pack, absorbing the heat generated by the battery. The temperature of the coolant will rise as the heat is carried away. By setting temperature control valves and sensors, the coolant temperature is monitored and the flow rate is adjusted to ensure that the coolant temperature is controlled within a reasonable range.

[0003] Traditional heat dissipation equipment relies on condenser tubes for heat dissipation, which is relatively simple. The heat on the surface of the condenser tubes cannot be dissipated in time, and the time required to complete the heat dissipation of the battery through the condenser tubes is relatively long, which reduces the efficiency of the heat dissipation equipment. Therefore, a heat dissipation equipment for lithium batteries in new energy ships is designed. Utility Model Content

[0004] The purpose of this utility model is to provide a heat dissipation device for lithium batteries in new energy ships, so as to solve the problem mentioned in the background art that the heat on the surface of the condenser tube cannot be dissipated in time, and the time required to complete the heat dissipation of the battery through the condenser tube is long, which reduces the efficiency of the heat dissipation device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation device for lithium batteries in new energy ships, including a heat dissipation base, a heat dissipation box on the top of the heat dissipation base, a condenser tube inside the heat dissipation box, a heat-conducting plate inside the heat dissipation base, a fan inside the heat-conducting plate, a heat dissipation plate at the bottom of the heat-conducting plate, multiple heat dissipation fins on the top of the heat dissipation plate, and multiple honeycomb plates on the top of the heat dissipation plate.

[0006] As a preferred embodiment of this utility model, multiple brackets are provided on both sides of the heat sink, and positioning plates are fixedly installed on both sides of the heat sink.

[0007] As a preferred embodiment of this utility model, the two positioning plates are symmetrically distributed around the center of the heat sink.

[0008] As a preferred embodiment of this utility model, two reinforcing plates are fixedly installed on both sides of the heat sink, and two second limiting holes are opened on both sides of the heat conduction plate.

[0009] As a preferred technical solution of this utility model, each of the four reinforcing plates has a first limiting hole on one side, and each of the four reinforcing plates has a limiting strip on one side. One end of each of the four limiting strips is respectively connected to the internal threads of the four first limiting holes and the four second limiting holes.

[0010] As a preferred embodiment of this utility model, the positions of the two adjacent reinforcing plates are corresponding.

[0011] As a preferred embodiment of this utility model, the multiple honeycomb panels are respectively located between multiple heat sinks, one end of the condenser tube is connected to a liquid transfer tube, and the top of the multiple heat sinks is in contact with the bottom of the heat conduction plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model incorporates a heat-conducting plate, a heat-dissipating plate, heat sinks, honeycomb panels, a reinforcing plate, and a limiting strip. Coolant is transferred to the interior of the condenser tube through a liquid transfer pipe. The outer surface of the condenser tube is in contact with the lithium battery, thereby absorbing heat from the battery surface. The surface of the heat-conducting plate is in contact with the bottom surface of the condenser tube, and heat is conducted to the surfaces of the heat sinks and multiple honeycomb panels. The combined use of the heat sinks and honeycomb panels increases the surface area in contact with air, thereby improving the efficiency of heat conduction and dissipation. By rotating the limiting strip in the opposite direction, the heat-conducting plate can be separated from the heat sink, facilitating the replacement of new heat sinks and honeycomb panels.

[0014] 2. This utility model, by setting a fan, a first limiting hole, a second limiting hole, and a liquid transfer pipe, ensures that the top of the heat sink and the honeycomb plate are tightly attached to the bottom surface of the heat-conducting plate. One end of the limiting strip is then embedded into the interior of the first and second limiting holes, and the three are connected by threads. This allows the heat-conducting plate and the heat sink to be limited and fixed. The heat-conducting plate is made of graphite, which can improve heat dissipation efficiency while maintaining lightness. The honeycomb plate has channels to increase the airflow path and enhance heat conduction efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a heat dissipation device for lithium batteries used in new energy ships:

[0022] Example 1:

[0023] like Figure 1-3 As shown, a heat dissipation device for lithium batteries in new energy ships includes a heat dissipation base 1, a heat dissipation box 2 on the top of the heat dissipation base 1, a condenser pipe 3 inside the heat dissipation box 2, a heat-conducting plate 5 inside the heat dissipation base 1, a fan 6 inside the heat-conducting plate 5, a heat dissipation plate 7 at the bottom of the heat-conducting plate 5, multiple heat dissipation fins 8 on the top of the heat dissipation plate 7, and multiple honeycomb plates 9 on the top of the heat dissipation plate 7. The heat dissipation plate 5 conducts heat to the surfaces of the heat dissipation fins 8 and the multiple honeycomb plates 9. The combined use of the heat dissipation fins 8 and the honeycomb plates 9 can increase the surface area in contact with the air, thereby improving the efficiency of heat conduction and dissipation. By rotating the limiting strip 13 in the opposite direction, the heat-conducting plate 5 can be separated from the heat dissipation plate 7, making it easy to replace with new heat dissipation fins 8 and honeycomb plates 9.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4As shown, each of the four reinforcing plates 10 has a first limiting hole 11 on one side and a limiting strip 13 on one side. One end of each limiting strip 13 is threadedly connected to the inside of the four first limiting holes 11 and the four second limiting holes 12, respectively. Multiple honeycomb plates 9 are located between multiple heat sinks 8. One end of the condenser tube 3 is inserted and connected to a liquid transfer tube 14. The tops of the multiple heat sinks 8 are in contact with the bottom of the heat-conducting plate 5. One end of the limiting strip 13 is embedded into the inside of the first limiting hole 11 and the second limiting hole 12. The three are threadedly connected, which can limit and fix the heat-conducting plate 5 and the heat sink 7. The heat-conducting plate 5 is made of graphite, which can improve heat dissipation efficiency while maintaining lightness. The honeycomb plate 9 has channels to increase the airflow path.

[0026] Working Principle: The heat generated by lithium batteries in new energy ships during operation requires a cooling system to maintain the battery's operating temperature range, ensuring its safety and high efficiency. Liquid cooling systems are a common cooling device for lithium batteries in new energy ships. Coolant flows through external cooling pipes of the battery pack, absorbing the heat generated by the battery. The coolant temperature rises as heat is carried away. Temperature control valves and sensors monitor the coolant temperature and adjust the flow rate to ensure the coolant temperature is controlled within a reasonable range. Traditional cooling devices dissipate heat through condenser tubes 3, which is relatively simple. The heat on the surface of condenser tubes 3 cannot be dissipated quickly enough, and the time required to complete battery cooling through condenser tubes 3 is relatively long, reducing the efficiency of the cooling device. Therefore, a cooling device for lithium batteries in new energy ships is designed. Coolant is transferred to the interior of condenser tubes 3 through a transfer pipe 14. The outer surface of condenser tubes 3 is in contact with the lithium battery... The heat-conducting plate 5 and the bottom surface of the condenser tube 3 are in contact with each other, so that the heat can be absorbed from the surface of the lithium battery. The heat-conducting plate 5 is in contact with the bottom surface of the condenser tube 3. The heat-conducting plate 5 conducts heat to the surface of the heat sink 8 and multiple honeycomb plates 9. The cooperation of the heat sink 8 and the honeycomb plates 9 can increase the surface area in contact with the air, thereby improving the heat conduction and dissipation efficiency. By rotating the limiting strip 13 in the opposite direction, the heat-conducting plate 5 and the heat sink 7 can be separated, making it easy to replace the heat sink 8 and the honeycomb plates 9 with new ones. After the top of the heat sink 8 and the honeycomb plates 9 are tightly attached to the bottom surface of the heat-conducting plate 5, one end of the limiting strip 13 is embedded into the first limiting hole 11 and the second limiting hole 12. The three are threaded together to limit and fix the heat-conducting plate 5 and the heat sink 7. The heat-conducting plate 5 is made of graphite, which can improve heat dissipation efficiency while maintaining lightness. The honeycomb plates 9 have channels to increase the airflow path and enhance the heat conduction efficiency.
