Description

Technical Field

[0001] The present application relates to the technical field of water cooling systems, and in particular to an external water inlet structure and a box structure. Background Art

[0002] The battery pack is the core of new energy vehicles, but the battery has poor heat dissipation performance and is greatly affected by temperature, which affects the application and promotion of new energy vehicles. The heat dissipation performance of the battery pack needs to be guaranteed. The water cooling system is an important part of the thermal management system in the battery pack, and the manufacturing process is complex and requires high precision.

[0003] In the related technology, the water cooling system includes a flange, two nylon tubes and a water cooling plate. A flow channel is opened on the water cooling plate. The flange is fixedly connected to the water cooling plate, and the two nylon tubes are connected through the flange and the water cooling plate, so that water enters the flow channel from one nylon tube and then flows out from the other nylon tube.

[0004] Since the flange is arranged on the water cooling plate and the battery pack needs to be arranged on the water cooling plate, the flange occupies a certain space of the water cooling plate, thereby reducing the cooling space of the battery pack on the water cooling plate, thus affecting the cooling effect of the battery pack. Utility Model Content

[0005] In order to improve the problem of nylon tubes occupying the space of the water cooling plate, the present application provides an external water inlet structure and a box structure.

[0006] The present application provides an external nozzle structure and a box structure, which adopts the following technical solutions:

[0007] An external water inlet structure includes a water cooling plate, a nylon tube and a flange. A flow channel is opened on the water cooling plate, a support plate is provided on the water cooling plate, the flow channel is opened on the support plate, the nylon tube and the flange are both arranged on the support plate, the nylon tube is connected to the flow channel, and the flange is used to fix the nylon tube.

[0008] By adopting the above technical solution, the support plate is set on the water-cooling plate, and the nylon tube and the flange are both set on the support plate, so that the nylon tube and the flange will not occupy the space of the water-cooling plate, so that the battery pack can completely occupy the cooling space of the water-cooling plate, and will not affect the cooling effect of the battery pack; at the same time, the nylon tube and the flange are both located on the support plate, so that the nylon tube and the flange are not in contact with the battery pack, thereby reducing the impact of water flowing out of the nylon tube on the battery pack when the sealing is poor.

[0009] Optionally, a profile is provided on the support plate, the nylon tube and the flange are both arranged on the profile, and a connecting pipe is provided on the profile, and the connecting pipe is used to connect the nylon tube and the flow channel.

[0010] By adopting the above technical solution, the nylon tube and the flange are both arranged on the profile, and the connecting pipe is connected to the nylon tube and the flow channel, so that the profile protects the connecting pipe, reduces the instability of the connection between the nylon tube and the connecting pipe during collision, and further enhances the connection stability of the nylon tube, the connecting pipe and the water cooling plate.

[0011] Optionally, a pre-buried groove is provided on the profile, and the pre-buried groove is used for pre-buried welding rings.

[0012] By adopting the above technical solution, the welding ring is pre-buried in the pre-buried groove, and the groove wall of the pre-buried groove limits the welding ring, so that the welding ring can be stably located in the pre-buried groove, thereby realizing the mutual fixation of the profile and the support plate, making the pre-buried welding ring between the profile and the support plate more firmly fixed, and further increasing the reliability of the profile and the support plate.

[0013] Optionally, the embedded groove extends along the circumference of the profile.

[0014] By adopting the above technical solution, the embedded groove extends along the circumference of the profile, so that the embedded welding ring can surround the circumference of the profile, allowing the welding ring to fix the profile circumferentially, thereby making the profile and the support plate more securely fixed and reducing the movement of the profile on the support plate due to impact.

[0015] Optionally, the profile is provided with a through hole, and a reinforcing plate is provided in the through hole.

[0016] By adopting the above technical solution, through holes are opened on the profile, the weight of the profile can be reduced, and the manufacturing cost of the profile can be saved, so that more profiles can be manufactured with the same volume of material; by arranging the reinforcing plate in the perforation, the reinforcing plate can increase the structural strength of the profile, so that the profile can ensure its own structural strength when the perforation is opened.

[0017] In the second aspect, the box structure provided by the present application adopts the following technical solution:

[0018] A box structure comprises an external water inlet structure and a box, wherein the box is arranged on a water cooling plate and is located between a battery pack and a nylon tube.

[0019] By adopting the above technical solution, the box is located between the battery pack and the nylon tube, so that the box can separate the battery pack and the nylon tube, so that the nylon tube cannot directly contact the battery pack. If there is a problem with the sealing of the nylon tube, the water leaking from the nylon tube will be limited by the box and will not directly contact the battery pack, thereby further improving the safety performance of the battery pack; at the same time, if the nylon tube is impacted, the nylon tube will abut the box, allowing the box to protect the battery pack, avoiding problems with the battery pack due to impact, reducing damage to the battery pack, increasing the safety performance of the battery pack, and improving the structural strength of the overall structure.

[0020] Optionally, the box body and the profile are fixed by argon arc welding.

[0021] By adopting the above technical solution, the profile is fixed to the box through argon arc welding. Argon arc welding is a high-quality welding method with the advantages of high weld quality, small welding deformation, strong adaptability, etc., which can increase the stability and safety between the profile and the box.

[0022] Optionally, the box body extends along the circumference of the water cooling plate.

[0023] By adopting the above technical solution, the box body is extended along the circumference of the water cooling plate so that the box body covers the battery pack, allowing the box body to prevent water from entering the box body from outside the box body, thereby improving the protection effect on the battery pack.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The support plate is arranged on the water-cooled plate, and the nylon tube and the flange are arranged on the support plate, so that the nylon tube and the flange will not occupy the space of the water-cooled plate, so that the battery pack can completely occupy the cooling space of the water-cooled plate, and will not affect the cooling effect of the battery pack; at the same time, the nylon tube and the flange are both located on the support plate, so that the nylon tube and the flange are not in contact with the battery pack, thereby reducing the impact of the nylon tube and the flange on the battery pack when the sealing is poor.

[0026] 2. The box is located between the battery pack and the nylon tube, so that the box can separate the battery pack and the nylon tube, so that the nylon tube cannot directly contact the battery pack. If there is a problem with the sealing of the nylon tube, the water leaking from the nylon tube will be limited by the box and will not directly contact the battery pack, thereby further improving the safety performance of the battery pack. At the same time, if the nylon tube is impacted, the nylon tube will abut the box, allowing the box to protect the battery pack, avoid problems with the battery pack due to impact, reduce damage to the battery pack, increase the safety performance of the battery pack, and improve the structural strength of the overall structure.
