Description

Technical Field

[0001] The utility model relates to the technical field of water cooling plates, and more specifically to a water cooling plate structure. Background Art

[0002] With the rapid development of new energy electric vehicles, the safety performance of batteries has received more and more attention, and the performance requirements for water cooling plates have also been gradually improved. Nowadays, as new energy vehicles gradually mature, customers have more stringent requirements on battery life and power. In order to meet their requirements for battery life and power, the number of battery modules has increased, resulting in the need for water cooling plates to have good cooling and heating functions for batteries. Sometimes, it is also necessary to break the previous assembly form to better match its battery pack.

[0003] like Figure 1 As shown, the water-cooled plate with two inlets and one outlet for coolant in the past is composed of an upper cold plate, a lower cold plate, a connecting pipe 1 3, a connecting pipe 2 4 and a connecting pipe 3 7. Although the design concept of two inlets and one outlet can be met, the installation of external joints and pipes has limitations on the installation space reserved for the battery pack, so that the two-inlet and one-out method of coolant cannot be used, which may cause uneven temperature when cooling or heating the battery. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art that the reserved installation space for the battery pack is limited and causes uneven temperature, and to provide a water cooling plate structure to solve the above shortcomings.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is:

[0006] A water-cooled plate structure comprises an upper cold plate and a flow channel plate welded to the upper cold plate, wherein a connecting pipe 1 and a connecting pipe 2 are arranged at the edge of the upper cold plate, and a reinforcing plate is welded on the upper cold plate near the connecting pipe 1 and the connecting pipe 2.

[0007] Preferably, the top of the reinforcing sheet protrudes upward to form a cavity inside.

[0008] Preferably, the position where the upper cold plate is mounted with the reinforcement plate has an opening.

[0009] Preferably, the cavity is connected to the flow channel of the flow channel plate through an opening.

[0010] Preferably, one of the connecting pipe 1 and the connecting pipe 2 is a water inlet pipe and the other is a water outlet pipe.

[0011] Preferably, the reinforcing sheet is arranged in a long strip shape.

[0012] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0013] The original installation form of connecting pipe three was replaced from the original installation of connecting pipe three and the water cooling plate to the installation of a reinforcing plate, breaking the limitation of the original water cooling plate due to insufficient installation space for the battery pack and the external joint pipeline of the whole vehicle. At the same time, the installation of the reinforcing plate can better make the battery heated evenly. With many branches and the use of the cavity of the reinforcing plate, the coolant can be better adjusted, so that the coolant can flow into the water cooling plate more evenly, and the battery can be cooled and heated more quickly and evenly.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0022] like Figure 2-4 A water-cooled plate structure comprises an upper cold plate 1 and a flow channel plate 2 welded to the upper cold plate 1, a connecting pipe 1 3 and a connecting pipe 2 4 are arranged at the edge of the upper cold plate 1, a long strip reinforcing sheet 5 is welded on the upper cold plate 1 near the connecting pipe 1 3 and the connecting pipe 2 4, the top of the reinforcing sheet 5 protrudes upward to form a cavity 6 inside, the position where the upper cold plate 1 is installed with the reinforcing sheet 5 has an opening, and the cavity 6 is connected with the flow channel of the flow channel plate 2 through the opening, so that the cooling water in the flow channel can pass through the cavity 6 of the reinforcing sheet 5.

[0023] The previous connecting pipe three 7 is replaced by the installation of the reinforcing plate 5 instead of the original connecting pipe three 7 and the water cooling plate, so that the coolant can pass through the cavity 6 of the reinforcing plate 5, so that the battery is heated more evenly. At the same time, it also solves the problem of multi-channel coolant introduction when the installation space is compact (the height of the reinforcing plate 5 is lower than the height of the original connecting pipe three 7, which can solve the problem of installation limitations in compact space).

[0024] One of the connecting pipe 1 3 and the connecting pipe 2 4 is a water inlet pipe and the other is a water outlet pipe. As for which one is the water inlet pipe or the water outlet pipe, it is selected according to actual use needs.

[0025] The utility model changes the installation form of the traditional connecting pipe 3 7, and uses a reinforcing plate 5 instead, which is welded to the water cooling plate. Since the reinforcing plate 5 does not need to be adapted to the pipeline and the external joint, and can be equivalent to the use of the connecting pipe 3 7 (such as Figure 5 As shown, the reinforcing sheet 5 can take in water and also can discharge water. The coolant enters the reinforcing sheet 5 through the flow channel, flows in the reinforcing sheet 5, and diverges in two directions at the outlet of the reinforcing sheet 5, which can better adjust the direction of the coolant), so that when the battery is working, the internal temperature of the battery can be better uniform, and at the same time, the limitation of the installation space of the water cooling plate will no longer exist.
