[0002] New energy vehicles are generally vehicles that use unconventional automotive fuels as a power source. Because of their advantages of low pollution, low noise, environmental protection and energy saving, their usage rate is increasing. The on-board batteries used in new energy vehicles are generally composed of multiple lithium batteries connected in series and parallel to form a battery pack, and then the battery packs are connected in series and installed in the battery box as a whole power source.

[0003] However, existing battery boxes may be affected by the environment or working hours during operation, which may cause the temperature of the battery to rise. If the heat cannot be effectively dissipated, it may directly affect the performance and service life of the battery and even cause certain safety hazards.

[0004] The patent "A New Energy Vehicle Battery Box" with authorization announcement number CN219739059U proposes a device that can cool the battery through water cooling. However, since the cooling tube also has a service life and works in a high temperature environment for a long time, if a leak occurs, it is easy to penetrate into the battery and cause damage to the battery. If damage occurs accidentally during driving, even if it does not penetrate into the battery, it will cause the battery to lose its heat dissipation device and pose a hidden danger. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the utility model is to provide a new energy vehicle heat dissipation battery box, which can protect the battery in time when internal leakage occurs, and allow users to easily find the leakage and carry out repairs.

[0008] A cold water pipe for cooling the battery body is arranged in the cavity, a plurality of water outlets are arranged on the bottom wall of the cavity, and a stopper is fixedly connected between two of the water outlets.

[0009] Furthermore, the moving assembly includes a fixing frame fixedly connected to the cavity, a first lead screw is rotatably connected to the fixing frame, and the first lead screw is threadedly connected to the supporting frame.

[0010] Furthermore, a fan is provided in the cavity, and a ventilation opening is provided on a side of the cavity opposite to the fan.

[0011] Furthermore, a shielding plate for shielding ventilation is provided in the vent, and a second lead screw is provided in the vent, and the second lead screw is threadedly connected to the shielding plate.

[0012] Furthermore, a water supply device is installed in the cavity, the water supply device is connected to a cold water pipe surrounding the battery body, and a cooler is installed on the water supply device.

[0013] Furthermore, an isolation plate for isolating dust is fixedly connected to the outside of the water outlet.

[0014] Furthermore, a partition plate is provided in the cavity for separating the battery body and the cold water pipe.

[0015] Compared with the prior art, the utility model has the following beneficial effects: when a water-cooled cold water pipe leaks, the utility model can lift the support frame and the battery body by moving the assembly to prevent water from entering, and can also drain water outwards through the block and the water outlet, assisting the user to find the damaged part as soon as possible and make repairs in time.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 , Figure 3 and Figure 5 The present embodiment provides a heat dissipation battery box for new energy vehicles, comprising a heat dissipation housing 11, a housing cover 12 mounted on the heat dissipation housing 11, and a cavity 15 provided in the heat dissipation housing 11, wherein a support frame 29 for installing a battery body 21 is slidably connected in the cavity 15 along the height direction of the heat dissipation housing 11, and a moving component 30 for driving the support frame 29 and the battery body 21 to move is provided in the cavity 15;

[0026] The moving assembly 30 includes a fixing frame 16 fixedly connected to the cavity 15 , a first lead screw 18 is rotatably connected to the fixing frame 16 , and the first lead screw 18 is threadedly connected to the supporting frame 29 .

[0027] By placing the battery body 21 on the support frame 29 , the support frame 29 can be driven to move upward or downward through the first lead screw 18 .

[0028] See also Figure 3 , Figure 4 and Figure 5 A fan 19 is provided in the cavity 15 , and a vent 20 is provided on a side of the cavity 15 opposite to the fan 19 .

[0029] A shielding plate 22 for shielding ventilation is disposed in the vent 20 , and a second lead screw 23 is disposed in the vent 20 . The second lead screw 23 is threadedly connected to the shielding plate 22 .

[0030] If the cold water pipe 25 is ruptured due to heat or leaks due to unexpected circumstances, the battery body 21 can be driven to move upward by moving the support frame 29 upward.

[0031] At this time, by moving the third screw 23, the shielding plate 22 can be driven to move downward, the vent 20 can be opened, and the fan 19 can be started to convert water cooling to wind cooling, and the battery body 21 can also be kept away from the leaked coolant.

[0032] When the internal temperature is too high, the fan 19 may be started to cool the battery body 21 simultaneously by combining air cooling and water cooling.

[0033] In order to prevent dust from entering the heat dissipation housing 11 when the fan 19 is not started, the shielding plate 22 always shields the vent 20 when the fan 19 is not started.

[0034] See also Figure 5 , Figure 6 and Figure 7 A water supply device 24 is installed in the cavity 15 , and a cold water pipe 25 surrounding the battery body 21 is connected to the water supply device 24 , and a cooler 17 is installed on the water supply device 24 .

[0035] The coolant can be continuously circulated to the cold water pipe 25 through the water supply device 24, and the liquid in the water supply device 24 can be continuously cooled through the cooler 17 to ensure that the water cooling is continuously maintained.

[0036] The bottom wall of the cavity 15 is provided with a plurality of water outlets 27 , and a stopper 26 is fixedly connected between two of the water outlets 27 .

[0037] Each water outlet 27 can be separated by the block 26. In this way, when leakage occurs, only the water outlet 27 within the leakage range will leak out, and the approximate location of the leakage can be found in the shortest time. At the same time, the water outlet 27 can ensure that the coolant will not be retained too much inside the cavity 15, reducing the risk of water mist or coolant entering the battery body 21.

[0038] An isolation plate 28 for isolating dust is fixedly connected to the outside of the water outlet 27 , and a partition plate 31 for isolating the battery body 21 and the cold water pipe 25 is provided in the cavity 15 .

[0039] The partition plate 31 can prevent the coolant from directly contacting the battery body 21 as much as possible.

[0040] See also Figure 2 The shell cover 12 is provided with a buckle 13 for connecting with the heat dissipation shell 11, and the heat dissipation shell 11 is provided with a connecting piece 14 rotatably connected with the shell cover 12.

[0041] The shell cover 12 can be easily opened by means of the buckle 13 and the connector 14, thus ensuring the convenience of use.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
