Description

Technical Field

At present, the battery thermal management system mainly uses water cooling, which has higher heat transfer efficiency and more uniform temperature control. Water cooling plates are mostly arranged at the bottom of the battery cell. A single set of water cooling plates can only cool the battery cell on the upper side, but not the battery cell on the lower side. The cooling effect is poor and the efficiency is low. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art, that is, poor cooling effect and low efficiency, and provides a double-sided cooling type water cooling plate to solve the above shortcomings.

[0004] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is:

[0005] A double-sided cooling water-cooling plate comprises a first flat plate and a second flat plate, wherein a first flow channel is welded to the inner surface of the first flat plate, and a second flow channel welded to the first flow channel is welded to the inner surface of the second flat plate.

[0006] Furthermore, one end of the first flat plate, the first flow channel and the second flow channel are all provided with a first mounting hole located on the same straight line.

[0007] Furthermore, a first connecting pipe is installed in the first installation hole.

[0008] Furthermore, one end of the second flat plate and the other ends of the first flow channel and the second flow channel are each provided with a second mounting hole located on the same straight line.

[0009] Furthermore, a second connecting pipe is installed in the second installation hole.

[0010] Furthermore, positioning holes are provided on the first flat plate, the second flat plate, the first flow channel and the second flow channel, and positioning pins are inserted into the positioning holes to position the double-sided cooling type water-cooling plate.

[0011] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0012] By optimizing the existing single-layer cooling structure of a flat plate and a flow channel, the two flow channels are welded, and the flat plates are welded on the outer sides of the two flow channels to form a water-cooled plate structure that can be cooled on both sides. The coolant enters through the water inlet pipe and flows through the two layers of flow channels and finally flows out. When the product space is insufficient, both sides of the water-cooled plate can be cooled, which can better improve the cooling effect and cooling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 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.

[0019] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0020] In order to solve the problem that the water cooling plate is mostly arranged at the bottom of the battery cell, a single set of water cooling plate can only cool the battery cell on the upper side, but not the battery cell on the lower side, resulting in poor cooling effect and low efficiency, refer to Figure 1-4 , this embodiment proposes the following technical solution.

[0021] A double-sided cooling water-cooling plate comprises a first flat plate 1 and a second flat plate 2. A first flow channel 3 is welded to the inner surface of the first flat plate 1, and a second flow channel 4 welded to the first flow channel 3 is welded to the inner surface of the second flat plate 2. The two-layer flat plate and the two-layer flow channel constitute a composite double-layer water-cooling plate structure that can be cooled on both sides. In the existing technology, only one flat plate is welded to one flow channel, and only single-sided cooling can be performed.

[0022] The first plate 1, the first flow channel 3, and the second flow channel 4 are all provided with a first mounting hole located on the same straight line at one end. Figure 4 As shown in a), a first connecting pipe 5 is installed inside, and the first connecting pipe 5 is a water inlet pipe or a water outlet pipe.

[0023] One end of the second plate 2 and the other ends of the first flow channel 3 and the second flow channel 4 are provided with a second mounting hole (such as Figure 4 The second connecting pipe 6 is installed in the second installation hole. If the first connecting pipe 5 is a water inlet pipe, the second connecting pipe 6 is a water outlet pipe. If the first connecting pipe 5 is a water outlet pipe, the second connecting pipe 6 is a water inlet pipe.

[0024] Positioning holes are provided on the first flat plate 1, the second flat plate 2, the first flow channel 3 and the second flow channel 4. During assembly, positioning pins are inserted into the positioning holes to position the double-sided cooling type water-cooling plate.

[0025] Working principle: The two connecting pipes are a water inlet pipe and a water outlet pipe. After water enters the water inlet pipe, the coolant flows from one end of the first flow channel 3 and the second flow channel 4 to the water outlet pipe at the other end. The coolant flows in the flow channel to achieve cooling, thereby cooling the battery cells on both sides of the water cooling plate.
