Detailed Description
In order that those skilled in the art will better understand the present utility model, a technical solution in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
In the description of the present utility model and the claims, the terms "upper", "lower", "inner", "outer" and "middle" in the drawings indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These terms are only used to better describe the present utility model and its embodiments and are not intended to limit the scope of the indicated devices, elements or components to the particular orientations or to configure and operate in the particular orientations. Also, some of the terms described above may be used to indicate other meanings in addition to orientation or positional relationships, for example, the term "upper" may also be used to indicate some sort of attachment or connection in some cases. The specific meaning of these terms in the present utility model will be understood by those of ordinary skill in the art according to the specific circumstances. In addition, the term "plurality" shall mean two as well as more than two.
Referring to fig. 1, the present embodiment provides a double water-cooled panel, which includes a double water-cooled panel body 1, a front plug 2, and a rear plug 3; the double water-cooling plate body 1 is in a cuboid shape, a cavity is formed in the double water-cooling plate body 1, and the front end and the rear end of the double water-cooling plate body 1 are both open ends; the front end and the rear end of the double water-cooling plate body 1 are respectively and fixedly provided with a front plug 2 and a rear plug 3 in a sealing manner, and are used for respectively closing open ends at the front end and the rear end of the water-cooling plate body 1; the upper end of the front plug 2 is provided with a water inlet 21 and a water outlet 22, and the water inlet 21 and the water outlet 22 are 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 movement of the medium in the entire cavity of the water-cooling plate body 1 through the S-shaped flow channel converts the flow direction of the cooling water in the water-cooling plate for multiple times, the flow path is long, the cooling effect on the battery module at the far end of the cooling water is poor, and the single water-cooling plate cannot be suitable for the battery module with larger volume.
In order to eliminate the above-mentioned problems, referring to fig. 1-2, in the present embodiment, the double water-cooled plate body 1 includes two first water-cooled plate bodies 5 and second water-cooled plate bodies 4 having the same structure; the first water-cooling plate body 5 and the second water-cooling plate body 4 are fixedly connected through side plates.
