Description

Technical Field

[0001] This utility model relates to the field of explosive cable technology, and more specifically, to a hollow heat dissipation structure for an automotive battery cover. Background Technology

[0002] The battery cover is a component of the power battery in new energy vehicles. It is a top cover on both sides of the power battery, and its main function is to prevent combustion and explosion due to excessive internal pressure. Aluminum covers have advantages such as explosion resistance, safety, and internal resistance. Electricity is the source of power for new energy vehicles. Currently, there are various types of aluminum battery covers for automobiles on the market. For example, the patent with the existing technology announcement number CN222422238U discloses an aluminum battery cover for automobiles. A heat sink is installed in the middle of the cover body, and heat dissipation holes are opened on the left and right sides of the heat sink. The heat dissipation holes are symmetrically located on the left and right sides of the inside of the cover body. During the long-term operation of the battery pack, a lot of heat is generated. The heat dissipation holes can effectively dissipate the heat generated by the battery. At the same time, the heat sink, as a metal with low heat, absorbs heat quickly and dissipates heat relatively quickly. Heat transfer can accelerate the heat dissipation effect of the battery. In addition, a filter screen is installed inside the heat dissipation holes. The filter screen can be easily removed from the inside of the cover body for cleaning or replacement. The filter screen also effectively prevents dust from entering the inside of the battery pack, avoiding short circuits in the battery pack.

[0003] When the above device is in use, rotating the rotating block inward can engage with the fixed block. Secondly, the fixed blocks are symmetrically installed on the outside of the battery pack body. The rotating block and the fixed block are fixedly connected by bolts. The installation of the cover plate body and the battery pack body provides convenience for the maintenance of the battery pack body, but its efficiency in heat dissipation of the car battery is poor, and it cannot quickly dissipate heat, thus affecting the service life of the car battery. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hollow heat dissipation structure for a car battery cover. The technical problem to be solved by the present invention is: how to increase the efficiency of the car cover in dissipating heat from the car battery.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hollow heat dissipation structure for an automotive battery cover, comprising a battery cover body, wherein the lower end of the battery cover body is provided with a plurality of supporting protrusions, and the end face of the supporting protrusions is provided with a plurality of hollow partition grooves.

[0006] The end face of the support protrusion is provided with a concave hollow groove, and the upper end of the battery cover plate is provided with a concave mounting groove on the side near the support protrusion. The interior of the concave mounting groove is provided with a heat dissipation plate.

[0007] In a preferred embodiment, the outer end face of the battery cover body is provided with a mounting ear plate.

[0008] In a preferred embodiment, the end face of the mounting ear plate is provided with a circular mounting groove.

[0009] In a preferred embodiment, the support protrusion has a ventilation groove inside.

[0010] In a preferred embodiment, the ventilation slot is provided with a plurality of vertical partition support plates inside.

[0011] In a preferred embodiment, the lower end of the heat sink is provided with a plurality of heat dissipation fins, and the end face of the heat sink is provided with a plurality of circular mounting holes.

[0012] In a preferred embodiment, the supporting protrusions are inclined at both ends in the main viewing direction, and the hollowed-out dividing grooves are through the end faces of the supporting protrusions.

[0013] In a preferred embodiment, the inner end face of the concave mounting groove is adapted to the outer end face of the heat sink.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In actual use, the corresponding arrangement of the hollowed-out partition groove, supporting protrusion, concave hollowed-out groove, ventilation groove, and vertical partition support plate allows the airflow generated at the bottom of the battery during vehicle operation to pass through the hollowed-out partition groove, concave hollowed-out groove, and ventilation groove, and circulate within the supporting protrusion, thereby dissipating heat from the vehicle battery and effectively increasing the battery's heat dissipation efficiency. At the same time, the supporting protrusion and vertical partition support plate can support the supporting protrusion, thus protecting the vehicle battery and preventing foreign objects at the bottom of the chassis from directly contacting the vehicle battery.

[0016] Simultaneously, with the concave mounting groove, heat sink, and heat sink fins in their corresponding configuration, the heat sink can come into contact with the car battery, allowing the heat from the car battery to be directly transferred to the heat sink. The heat absorbed by the heat sink will then be conducted to the heat sink fins, and the airflow generated during car operation will dissipate heat from the heat sink fins.

[0027] This utility model provides a hollow heat dissipation structure for an automotive battery cover, such as... Figure 1 and 2 As shown, it includes a battery cover body 1. The lower end of the battery cover body 1 is provided with a plurality of support protrusions 5. The end face of the support protrusions 5 is provided with a plurality of hollow partition grooves 4. The support protrusions 5 can support and reinforce the battery cover body 1, thereby effectively increasing the protective effect of the battery cover body 1.

[0028] The outer end face of the battery cover body 1 is provided with mounting ear plate 2. The end face of the mounting ear plate 2 is provided with a circular mounting groove 3, which can be bolted through the inside of the circular mounting groove 3 to install the mounting ear plate 2 at the lower end of the car battery, thereby effectively increasing the stability of the battery cover body 1 installation. The support protrusion 5 is set in an inclined state at both ends in the main viewing direction. During the car's operation, the inclined state at both ends of the support protrusion 5 can facilitate airflow from one end of the support protrusion 5, thereby facilitating airflow circulation inside the support protrusion 5 and effectively increasing the efficiency and effect of heat dissipation for the car battery. At the same time, when the battery cover body 1 collides with foreign objects on the ground during the car's operation, the support protrusion 5 can prevent foreign objects from directly contacting the battery cover body 1, thereby preventing damage to the car battery during impact. The hollow partition groove 4 is set in a through state on the end face of the support protrusion 5, which can increase the air inlet of the support protrusion 5 through the hollow partition groove 4, thereby effectively increasing the efficiency and effect of battery heat dissipation.

[0029] like Figure 3 and 4As shown, the end face of the supporting protrusion 5 is provided with a concave hollow groove 6, and the upper end of the battery cover body 1 is provided with a concave mounting groove 9 on the side near the supporting protrusion 5. The concave mounting groove 9 is provided with a heat dissipation plate 10. When installing the battery cover body 1, the heat dissipation plate 10 can be installed inside the concave mounting groove 9. When installing the battery cover body 1, the heat dissipation plate 10 needs to be installed inside the concave mounting groove 9. After the electromagnetic cover body 1 is installed, the heat dissipation plate 10 is connected to the car battery by bolts passing through the inside of the circular mounting hole 12. So that when the car battery temperature is too high, the heat of the battery will be transferred to the heat dissipation plate 10.

[0030] The support protrusion 5 has a ventilation groove 7 inside, and the ventilation groove 7 has multiple vertical partition support plates 8 inside. The lower end of the heat sink 10 has multiple heat sink fins 11. The heat from the heat sink 10 is conducted to the heat sink fins 11. The wind generated during the car's operation passes through the interior of the multiple heat sink fins 11, thereby dissipating heat from the heat sink fins 11 and effectively increasing the efficiency and effect of the heat sink 10 in cooling the car battery.

[0031] The heat sink 10 has multiple circular mounting holes 12 on its end face, and the inner end face of the concave mounting groove 9 is adapted to the outer end face of the heat sink 10.
