As shown in fig. 1-7, the present embodiment provides a water cooling plate with a side-by-side water pipe structure for a battery module, which includes a rectangular water cooling plate body 100, wherein a cavity is configured in the water cooling plate body 100, and both front and rear ends of the water cooling plate body 100 are open ends; the front end cap 200 and the rear end cap 300 are respectively and hermetically fixed at the front end and the rear end of the water-cooling plate body 100, so as to respectively seal the open ends of the front end and the rear end of the water-cooling plate body 100, the water inlet unit 400 and the water outlet unit 500 are mounted at the upper end of the water-cooling plate body 100, the water inlet unit 400 and the water outlet unit 500 are both positioned at the front end of the water-cooling plate body 100, and the water inlet unit 400 and the water outlet unit 500 are both communicated with the cavity.

It can be understood that, when the conventional water cooling plate works, relatively low temperature water (cold water) enters the cavity in the water cooling plate body 100 from the water inlet unit 400, circulates through the S-shaped flow channel, exchanges heat with the battery module, and then increases the temperature of the water, and relatively high temperature water flows out of the water cooling plate from the cavity in the water cooling plate body 100 through the water outlet unit 500, thereby completing one heat dissipation cycle for the battery module.

However, the movement of the medium in the entire cavity of the water-cooling plate body 100 through the S-shaped flow channels converts the flow direction of the cooling water inside the water-cooling plate multiple times, the flow is long, and the cooling effect on the battery module at the far end of the cooling water is poor.

In order to eliminate the above-mentioned problems, in the present embodiment, a plurality of vertical partitions 110 are disposed in the cavity of the water-cooling plate body 100 at intervals, so as to divide the cavity of the water-cooling plate body 100 into a plurality of independent flow channel spaces 600, and obviously, the number of the flow channel spaces 600 is one more than the number of the partitions 110; each of the flow path spaces 600 communicates with the water inlet unit 400 and the water outlet unit 500.

In other words, the front and rear ends of the partition 110 are respectively hermetically connected to the inner end surfaces of the front bulkhead 200 and the rear bulkhead 300 such that the plurality of independent flow path spaces 600 are not communicated with each other.

Thus, in the water cooling plate having the side-by-side water pipe structure according to the present embodiment, when the water cooling plate is in operation, the low-temperature water enters each of the flow passage spaces 600 in the water cooling plate body 100 from the water inlet unit 400, and then the medium circulates through the flow passage in each of the flow passage spaces 600, exchanges heat with the battery module, and then flows out of the water cooling plate from each of the flow passage spaces 600 in the water cooling plate body 100 through the water outlet unit 500. Therefore, the medium moves through the flow channels in each flow channel space 600 in the water cooling plate body 100, the number of times of switching the flow direction of the cooling water in the water cooling plate is obviously smaller, the flow is shortened, and the cooling effect of the battery module at the far end of the cooling water is improved.

Specifically, four partitions 110 are disposed at intervals in the cavity of the water-cooling plate body 100 to divide the cavity of the water-cooling plate body 100 into five flow passage spaces 600. Preferably, the water inlet unit 400 includes water inlet connectors 410 equal to the number of the flow channel spaces 600, and the installation positions of the water inlet connectors 410 are in one-to-one correspondence with the flow channel spaces 600; the water outlet unit 500 includes water outlet joints 510 equal in number to the flow path spaces 600, and the installation positions of the water outlet joints 510 are in one-to-one correspondence with the flow path spaces 600.

In other words, the five water inlet connectors 410 and the five water outlet connectors 510 are alternately arranged, wherein one set of the water inlet connectors 410 and the water outlet connectors 510 corresponds to one flow channel space 600. The low-temperature water respectively enters the five flow passage spaces 600 in the water-cooling plate body 100 through the respective water inlet connectors 410, and is discharged from the five flow passage spaces 600 in the water-cooling plate body 100 through the respective water outlet connectors 510 after heat exchange with the battery module.

It should be noted that, the plurality of vertical partition plates 110 may be configured in an array to uniformly divide the cavity inside the water-cooling plate body 100 into a plurality of uniform flow channel spaces 600, so as to obtain an overall uniform heat exchange effect of the water-cooling plate; the plurality of partition plates 110 may be configured in non-equidistant manner, so as to divide the cavity inside the water-cooling plate body 100 into a plurality of flow channel spaces 600 with different sizes, thereby obtaining the heat exchange effect of the water-cooling plate with locally protruding portions. All water cooling plates which divide the interior of the water cooling plate body 100 into a plurality of water cooling plates respectively circulating cooling media belong to the category of the present embodiment.

In this embodiment, a vertical runner plate 120 is disposed in each of the plurality of runner spaces 600 to divide the runner spaces 600 into a water inlet runner 610 and a water return runner 620; and, each of the water inlet flow passages 610 communicates with the water inlet unit 400, and each of the water return flow passages 620 communicates with the water outlet unit 500.

In other words, the front end of the flow channel plate 120 is hermetically connected to the inner end surface of the front plug 200, and the rear end of the flow channel plate 120 is configured not to contact the inner end surface of the rear plug 300, so that a channel for exchanging inflow and return water is formed between the rear end of the flow channel plate 120 and the inner end surface of the rear plug 300.

Specifically, the five sets of water inlet connectors 410 and water outlet connectors 510 respectively correspond to the five flow channel spaces 600, and each water inlet connector 410 respectively corresponds to the respective water inlet flow channel 610, and each water outlet connector 510 respectively corresponds to the respective water return flow channel 620.

Thus, in operation, the water cooling plate having the side-by-side water pipe structure of the present embodiment is configured such that low-temperature water enters the water inlet channels 610 of the respective channel spaces 600 from the respective water inlet connectors 410, medium circulates through the U-shaped channels in the respective channel spaces 600, and after heat exchange with the battery module, the high-temperature water flows out of the water cooling plate from the water return channels 620 of the respective channel spaces 600 through the water outlet connectors 510. Therefore, the medium moves through the U-shaped flow channels in each flow channel space in the water cooling plate body 100, the number of times of flow direction conversion of the cooling water in the water cooling plate is further smaller, the flow is shortened, and the cooling effect of the battery module at the far end of the cooling water is further improved.

In this embodiment, a plurality of vertical flow dividing plates 130 are disposed in the water inlet channels 610 and the water return channels 620 to divide the water inlet channels 610 and the water return channels 620 into a plurality of sub water inlet channels 611 and sub water return channels 621; and, each sub-water inlet channel 611 communicates with the water inlet unit 400, and each sub-water return channel 621 communicates with the water outlet unit 500. It will be appreciated that the number of sub-channels 611, 621 is one greater than the number of splitter plates 130.

In other words, the front and rear ends of the flow dividing plate 130 are respectively configured not to contact the inner end surfaces of the front and rear plugs 200 and 300, so that a flow dividing region for water inflow is formed between the front end of the water inlet flow dividing plate 131 in the water inlet flow channel 610 and the inner end surface of the front plug 200, and a collecting region for water inlet and return water exchange channels is formed between the rear end of the water inlet flow dividing plate 131 and the inner end surface of the rear plug 300; a converging region of the outlet water is formed between the front end of the backwater flow dividing plate 132 in the backwater flow passage 620 and the inner end surface of the front plug 200, and a flow dividing region of the water inlet and backwater exchange passage is formed between the rear end of the backwater flow dividing plate 132 and the inner end surface of the rear plug 300.

Thus, in operation, the water cooling plate with the side-by-side water pipe structure of the present embodiment, low-temperature water enters the sub-water inlet channels 611 of the respective water inlet channels 610 from the respective water inlet connectors 410, medium circulates through the U-shaped channels in the respective channel spaces 600, and after heat exchange with the battery module, the high-temperature water flows out of the water cooling plate from the respective sub-water return channels 621 through the water outlet connectors 510. Therefore, the medium moves through the U-shaped flow channels in each sub water inlet channel 611 and sub water return channel 621 in the water cooling plate body 100, and uniformly circulates in each flow channel space 600 in the water cooling plate, thereby obtaining uniform heat exchange effect in each flow channel space 600 region.

As an embodiment, a vertical splitter 130 is disposed in each of the water inlet channels 610 and the water return channels 620 to divide the water inlet channels 610 and the water return channels 620 into two sub water inlet channels 611 and sub water return channels 621.

In this embodiment, the front plug 200 and the rear plug 300 have the same structure, and each include an end plate 210 and a bar-shaped plug 220 disposed on an inner end surface of the end plate 210, where an outer contour of the end plate 210 is matched with an outer contour of the water-cooled plate body 100 to obtain a flat overall water-cooled plate structure, and an outer contour of the bar-shaped plug 220 is matched with an inner contour of the water-cooled plate body 100, that is, an outer contour of the bar-shaped plug 220 is matched with a cavity contour of the water-cooled plate body 100 to obtain a sealing effect of the front plug 200 and the rear plug 300 on the water-cooled plate body 100. Preferably, the end plate 210 and the bar-shaped block 220 are integrally formed.

In other words, the inner end surfaces 230 of the bar-shaped plug 220 are the inner end surfaces of the front plug 200 and the rear plug 300. That is, the front and rear ends of the partition 110 are respectively hermetically connected to the inner end surfaces 230 of the front and rear stopper bar-shaped stoppers 220; the front end of the runner plate 120 is connected with the inner end surface 230 of the front plug strip-shaped block 220 in a sealing manner, and the rear end of the runner plate 120 is configured not to contact with the inner end surface 230 of the rear plug strip-shaped block 220; the front and rear ends of the manifold 130 are respectively configured to be non-contacting with the inner end surfaces 230 of the front and rear plug strip plugs 220.

It can be appreciated that, for a battery module with a larger size, the matched water-cooling plate body 100 is also larger in size, and the corresponding mold and equipment for processing the water-cooling plate body 100 need to be larger in size, so that the processing cost is higher.

For this reason, in order to reduce the processing difficulty, the water-cooled plate body 100 of the present embodiment is arranged in the same side-by-side configuration, so as to eliminate the enlargement of the processing mold and equipment. Specifically, the water-cooling plate body 100 includes a first sub-body 140 and a second sub-body 150 with the same structure, wherein the first sub-body 140 and the second sub-body 150 are configured in a mirror image, and a first inner side plate 141 of the first sub-body 140 and a second inner side plate 151 of the second sub-body 150 are connected.

In other words, the inner side plates of the first sub-body 140 and the second sub-body 150 are fixedly connected to form the water-cooled plate body 100, and the first inner side plate 141 and the second inner side plate 151 are combined to form the partition plate 110 or the flow channel plate 120 of the water-cooled plate body 100.

Specifically, if the number of the flow channel spaces 600 is an odd number, the first inner side plate 141 and the second inner side plate 151 are combined to form the flow channel plate 120 of the water-cooled plate body 100 (five flow channel spaces 600 are shown in fig. 6); if the number of the flow channel spaces 600 is even, the first inner side plate 141 and the second inner side plate 151 are combined to form the partition plate 110 of the water-cooled plate body 100.

Through the above arrangement, the working principle of this embodiment is:

The cooling water flows into the water inlet flow channel 610 from each water inlet joint 410 and flows into each sub water inlet flow channel 611 through the water inlet flow dividing plate 131, and then flows into each sub water return flow channel 621 of the water return flow channel 620 after being collected through the water inlet and water return exchange channels, and exchanges heat with the battery module during the period, the heat exchanged water is collected at the front end of the water return flow channel 620 and flows out from each water outlet joint 510, and the cooling cycle of the battery module is completed.

The water flow is only turned once in the water cooling plate body 100 to finish cooling the battery module, a U-shaped loop is formed, and compared with the water flow resistance of the water cooling plate with an S-shaped structure, the flow resistance of the water cooling plate is greatly reduced, the power of a PACK water cooling water pump is reduced, and the consumption of energy sources is reduced; the U-shaped structure improves the cooling efficiency, thoroughly solves the problems that the cooling medium of the S-shaped water channel is poor in the cooling of the second half section due to the fact that the cooling medium absorbs the heat of the front channel, improves the temperature uniformity of the inside of the whole battery PACK, and reduces the temperature difference between the battery modules.
