Description

Technical Field

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

[0002] With the rapid development of new energy electric vehicles, battery safety performance has received more and more attention, and as a result, the performance requirements for water cooling plates are also gradually increasing. Nowadays, with the advent of blade batteries, water cooling plates not only need to have good functions of cooling and heating batteries, but sometimes they also need to break the previous assembly form to better match their battery packs. This will also be an innovation in the design and processing of water cooling plates, and a new attempt.

[0003] The current water cooling plates are all composed of harmonica pipes, water chambers and connecting pipes (such as Figure 1 As shown), there are water chambers on both sides and a harmonica tube in the middle. Although it can cool down or heat up the battery, it is difficult for the microchannel to make the battery heat evenly and it is limited to square or soft-pack batteries. This will limit the use of water-cooled plates. The coolant distribution problem in the microchannel cannot be well adjusted, which may cause uneven temperature when cooling or heating the battery. The existing water-cooled plates are difficult to apply to the cooling of current blade batteries. Utility Model Content

[0004] The utility model aims to overcome the deficiencies in the prior art and provides a water cooling plate with harmonica pipes arranged longitudinally to solve the above deficiencies.

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

[0006] A water-cooling plate with harmonica tubes arranged longitudinally comprises a first water chamber, a harmonica tube and a second water chamber, 29 harmonica tubes arranged longitudinally are arranged between the first water chamber and the second water chamber, two ends of the harmonica tubes are respectively connected to the first water chamber and the second water chamber, and the 29 harmonica tubes are arranged parallel to each other.

[0007] Furthermore, the front end of the first water chamber and the front end of the second water chamber are both L-shaped structures, and the L-shaped ends of the first water chamber and the second water chamber are both provided with a first blocking cover, a second blocking cover and a third blocking cover.

[0008] Furthermore, a fourth blocking cover and a fifth blocking cover are provided at the rear ends of the first water chamber and the second water chamber.

[0009] Furthermore, the first blocking cover, the second blocking cover and the third blocking cover seal the three ports at the front ends of the first water chamber and the second water chamber, and the fourth blocking cover and the fifth blocking cover seal the two ports at the rear ends of the first water chamber and the second water chamber.

[0010] Furthermore, the first water chamber and the second water chamber are both connected with connecting pipes.

[0011] Furthermore, two adjacent harmonica pipes are placed on two sides of the battery.

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

[0013] 1. The previous installation direction of the harmonica tube and the water chamber was changed from horizontal installation to vertical installation, so that both sides of the battery pack can contact the harmonica tube. This not only solves the assembly of the blade battery, but also can better make the battery heat evenly, breaking the limitations of the original water cooling plate.

[0014] 2. One connecting pipe is the water inlet pipe and the other connecting pipe is the water outlet pipe, one in and one out. Multiple harmonica pipes form many branches and microchannels, which can better regulate the coolant and make the coolant flow into the water cooling plate more evenly, which can cool down and heat up the battery 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] In order to solve the problem that the existing water cooling plate is difficult to apply to the cooling of the current blade battery and has cooling limitations, this embodiment proposes the following technical solutions:

[0023] like Figure 2 As shown, this embodiment proposes a water-cooling plate with harmonica tubes arranged longitudinally, including a first water chamber 1, a harmonica tube 2 and a second water chamber 3, 29 harmonica tubes 2 arranged longitudinally are arranged between the first water chamber 1 and the second water chamber 3, both ends of the harmonica tube 2 are respectively connected to the first water chamber 1 and the second water chamber 3, the 29 harmonica tubes 2 are arranged parallel to each other, and two adjacent harmonica tubes 2 are placed on both sides of a battery.

[0024] In this embodiment, if Figure 3-4 As shown, the front end of the first water chamber 1 and the front end of the second water chamber 3 are both L-shaped structures, and the L-shaped ends of the first water chamber 1 and the second water chamber 3 are both provided with a first plugging cover 4, a second plugging cover 5 and a third plugging cover 6. The rear end of the first water chamber 1 and the rear end of the second water chamber 3 are both provided with a fourth plugging cover 7 and a fifth plugging cover 8. The first plugging cover 4, the second plugging cover 5 and the third plugging cover 6 seal the three ports at the front end of the first water chamber 1 and the second water chamber 3 to maintain the sealing of the front end of the first water chamber 1 and the second water chamber 3, and the fourth plugging cover 7 and the fifth plugging cover 8 seal the two ports at the rear end of the first water chamber 1 and the second water chamber 3 to maintain the sealing of the rear end of the first water chamber 1 and the second water chamber 3.

[0025] In this embodiment, the first water chamber 1 and the second water chamber 3 are both connected with connecting pipes 9, one connecting pipe 9 is a water inlet pipe and the other connecting pipe 9 is a water outlet pipe. One inlet and one outlet, multiple harmonica pipes 2 form multiple branches and use microchannels, which can better regulate the coolant, so that the coolant flows into the water cooling plate more evenly, and the battery can be cooled and heated more quickly and evenly.

[0026] like Figure 2 As shown, the previous installation direction of the harmonica tube and the water chamber is changed from the original horizontal installation of the harmonica tube to the vertical installation, and the harmonica tube 2 is welded to the water chambers on both sides. Since the battery is installed between the two harmonica tubes 2, both sides of the battery pack can contact the harmonica tube 2. The coolant enters a water chamber from a connecting tube 9, flows into another water chamber through the harmonica tube 2, and finally flows out from another connecting tube 9 to form a cycle, which not only solves the assembly of the blade battery, but also can better make the battery heated evenly, breaking the limitations of the original water cooling plate. Therefore, when the battery is working, the internal temperature of the battery can be better uniform, and at the same time, the limitations of the water cooling plate on its blade battery installation will no longer exist.
