In addition, the term "plurality" shall mean two as well as more than two.
As shown in fig. 1-8, the present embodiment provides a water-cooling plate for a battery module, which includes a rectangular water-cooling plate body 1, wherein a cavity is configured in the water-cooling plate body 1, and both front and rear ends of the water-cooling plate body 1 are open ends; the front end and the rear end of the water-cooling plate body 1 are respectively and hermetically fixed with a front plug 2 and a rear plug 3, which are used for respectively closing the open ends of the front end and the rear end of the water-cooling plate body 1, a water inlet 21 and a water outlet 22 are arranged at the upper end of the front plug 2, and the water inlet 21 and the water outlet 22 are both communicated with the cavity.
It will be appreciated that when the conventional water cooling plate works, relatively low temperature water (cold water) enters the cavity in the water cooling plate body 1 from the water inlet 21, circulates through the S-shaped flow channel, exchanges heat with the battery module, and then rises in temperature, and relatively high temperature water flows out of the water cooling plate from the cavity in the water cooling plate body 1 through the water outlet 22, thus completing one heat dissipation cycle for the battery module.
However, the medium moves in the whole cavity of the water cooling plate body 1 through the S-shaped flow channel, the cooling water in the water cooling plate changes the flow direction for a plurality of 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 this embodiment, a plurality of vertical partitions 14 are disposed in the cavity of the water-cooling plate body 1 at intervals, so as to divide the cavity of the water-cooling plate body 1 into a plurality of independent flow channel spaces, and obviously, the number of the flow channel spaces is one more than that of the partitions 14; a water diversion channel 31 communicating with the water inlet 21 and a water collection channel 32 communicating with the water outlet 22 are arranged in the front plug 2, and each flow channel space is communicated with the water diversion channel 31 and the water collection channel 32.
In other words, the front and rear ends of the partition 14 are respectively hermetically connected to the inner end surfaces of the front bulkhead 2 and the rear bulkhead 3 so that the plurality of independent flow passage spaces are not communicated with each other.
Thus, in the water-cooled plate of this embodiment, during operation, low-temperature water enters the water diversion channel 31 from the water inlet 21, and after being split, enters each flow channel space in the water-cooled plate body 1, the medium circulates in each flow channel space through the flow channels, exchanges heat with the battery module, and then, the high-temperature water is collected into the water collection channel 32 from each flow channel space in the water-cooled plate body 1, and finally, flows out of the water-cooled plate through the water outlet 22. Therefore, the medium moves in each flow passage space in the water cooling plate body 1 through the flow passages, the number of times of converting the flow direction of the cooling water in the water cooling plate is obviously less, the flow is shortened, and the cooling effect of the battery module at the far end of the cooling water is improved.
Specifically, two partition plates 14 are arranged in the cavity of the water-cooling plate body 1 at intervals to divide the cavity of the water-cooling plate body 1 into three flow passage spaces, and the three flow passage spaces are communicated with the water diversion channel 31 and the water collection channel 32. The low-temperature water is shunted by the water diversion channel 31 and enters three flow channel spaces in the water-cooling plate body 1, and after heat exchange with the battery module, the high-temperature water is converged into the water collection channel 32 from the three flow channel spaces in the water-cooling plate body 1.
It should be noted that, the plurality of vertical partition plates 14 may be configured in an array to uniformly divide the cavity inside the water-cooling plate body 1 into a plurality of flow channel spaces, so as to obtain an overall uniform heat exchange effect of the water-cooling plate; the plurality of partition plates 14 can also be configured in a non-equidistant way, and the cavity inside the water-cooling plate body 1 is divided into a plurality of flow passage spaces with different sizes, so that the heat exchange effect of the water-cooling plate with local protrusions is obtained. All water cooling plates which divide the interior of the water cooling plate body 1 into a plurality of water cooling plates respectively circulating cooling media belong to the category of the embodiment.
In this embodiment, a vertical runner plate 33 is disposed in each of the plurality of runner spaces to divide the runner space into a water inlet runner and a water return runner; and, the water inlet flow passage of each flow passage space is communicated with the water diversion passage 31, and the water return flow passage of each flow passage space is communicated with the water collection passage 32.
In other words, the front end of the flow channel plate 33 is sealingly connected to the inner end surface of the front plug 2, and the rear end of the flow channel plate 33 is configured not to contact with the inner end surface of the rear plug 3, so that a channel for exchanging inflow water and return water is formed between the rear end of the flow channel plate 33 and the inner end surface of the rear plug 3.
Thus, in the water cooling plate of this embodiment, during operation, low-temperature water enters from the water inlet 21, and after being split by the water diversion channel 31, enters the water inlet channels of each channel space, the medium circulates in each channel space through the U-shaped channels, after heat exchange with the battery module, the high-temperature water is collected into the water collecting channel 32 from the water return channels of each channel space, and finally flows out of the water cooling plate through the water outlet 22. Therefore, the medium moves in each flow passage space in the water cooling plate body 1 through the U-shaped flow passages, 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.
Specifically, the partition plate 14 and the flow channel plate 33 are cooperatively disposed to divide the internal cavity of the water-cooling plate body 1 into a first water inlet channel 15, a first water return channel 16, a second water inlet channel 17, a second water return channel 18, a third water inlet channel 19 and a third water return channel 20 from left to right. The low-temperature water is shunted by the water diversion channel 31, enters the first water inlet channel 15, the second water inlet channel 17 and the third water inlet channel 19 respectively, flows into the first water return channel 16, the second water return channel 18 and the third water return channel 20 respectively through the water inlet and water return exchange channels, exchanges heat with the battery module during the process, and is converged into the water collection channel 32 from the first water return channel 16, the second water return channel 18 and the third water return channel 20.
In this embodiment, the side of the water diversion channel 31 near the water cooling plate body 1 is provided with a plurality of water inlets, and the water inlets are respectively corresponding to water inlets communicating with the respective flow channel spaces. Thus, the low-temperature water introduced from the water inlet 21 is branched through the respective water inlet holes of the water distribution channel 31 and then introduced into the water inlet channels of the respective channel spaces, respectively. It is understood that the number of water inlet holes is the same as the number of flow passage spaces.
The side surface of the water collecting channel 32, which is close to the water cooling plate body 1, is provided with a plurality of water outlets, and the water outlets are respectively corresponding to the water return channels communicated with the channel spaces. Therefore, after the medium circulates in the U-shaped flow passage space and exchanges heat with the battery module, the high-temperature water in the backwater flow passage passes through the water collecting passage 32 of each water outlet Kong Huiru. It is understood that the number of water outlets is also the same as the number of flow passage spaces.
In other words, the water diversion channels 31 are provided with water inlets of the same number as the channel spaces, and each water inlet is respectively communicated with the water inlet channel of one channel space. The water collecting channels 32 are provided with water outlets the same in number as the flow channel spaces, and each water outlet is respectively communicated with a water return flow channel of one flow channel space.
Specifically, when the water cooling plate works, cooling water flows into the water diversion channel 31 from the water inlet 21, and flows into the first water inlet flow channel 15, the second water inlet flow channel 17 and the third water inlet flow channel 19 respectively through the first water inlet hole 25, the second water inlet hole 27 and the third water inlet hole 29 of the water diversion channel 31; and then the cooling water respectively flows into the first water return flow channel 16, the second water return flow channel 18 and the third water return flow channel 20 through the channels for water inlet and water return exchange, and exchanges heat with the battery module during the period, and the water after heat exchange passes through the first water return hole 26, the second water return hole 28 and the third water return hole 30, is converged into the water collecting channel 32 from the first water return flow channel 16, the second water return flow channel 18 and the third water return flow channel 20, flows out from the water outlet 22, and completes the cooling circulation of the battery module.
In order to facilitate the arrangement of the water diversion channel 31 and the water collection channel 32, and the water inlet and outlet thereof, in the present embodiment, the water diversion channel 31 and the water collection channel 32 are arranged in layers up and down. And preferably, the water diversion channel 31 is positioned at an upper layer, and the water collection channel 32 is positioned at a lower layer, thereby facilitating the flow of the cooling medium.
In order to facilitate the processing of the water diversion channel 31 and the water collection channel 32, and the water inlet and outlet thereof, in this embodiment, the water diversion channel 31 and the water collection channel 32 extend to the outer end surface of the front plug 2, so that the water diversion channel 31 and the water collection channel 32 can be directly opened on the outer end surface of the front plug 2 body. Correspondingly, a first sealing strip 23 is arranged at one end of the water diversion channel 31 far away from the water inlet, and a second sealing strip 24 is arranged at one end of the water collection channel 32 far away from the water outlet, so as to respectively seal the water diversion channel 31 and the water collection channel 32.
In the present embodiment, the water-cooled panel body 1 includes an upper panel 11, a pair of side panels 12, and a lower panel 13, so that the water-cooled panel body 1 is enclosed by the upper panel 11, the two side panels 12, and the lower panel 13, and a cavity is formed therein; the plurality of partition plates 14 and the flow channel plate 33 are all configured to be parallel to the side plate 12, and the upper ends of the plurality of partition plates 14 and the flow channel plate 33 are all in sealing connection with the lower end face of the upper panel 11, and the lower ends are all in sealing connection with the upper end face of the lower panel 13.
Through the above arrangement, the working principle of this embodiment is:
Cooling water flows into the water diversion channel 31 from the water inlet 21, and flows into the first water inlet flow channel 15, the second water inlet flow channel 17 and the third water inlet flow channel 19 respectively through the diversion of the first water inlet hole 25, the second water inlet hole 27 and the third water inlet hole 29 of the water diversion channel 31; and then the cooling water respectively flows into the first water return flow channel 16, the second water return flow channel 18 and the third water return flow channel 20 through the channels for water inlet and water return exchange, and exchanges heat with the battery module during the period, and the water after heat exchange passes through the first water return hole 26, the second water return hole 28 and the third water return hole 30, is converged into the water collecting channel 32 from the first water return flow channel 16, the second water return flow channel 18 and the third water return flow channel 20, flows out from the water outlet 22, and completes the cooling circulation of the battery module.
