Description

Function integrated lower box

Technical Field

The utility model relates to a box under function integrated type.

Background

The bottom of a battery pack of the electric automobile is provided with a lower box body to play a role in protection and support, a liquid cooling assembly and a fireproof material which are matched with the battery pack are arranged on the existing lower box body, the liquid cooling assembly is used for quickly taking away heat dissipated by the battery pack under the matching action of a heat management system so as to prevent the battery pack from having too high temperature, and the fireproof material can effectively prevent the battery pack from thermal runaway or burning; in addition, heat insulation cotton needs to be laid in the lower box body to prevent the loss of cold energy, and all the components and the lower box body are independent from each other, so that the assembly process of the lower box body is complicated, and the production efficiency is low; and occupies a larger volume, so that the space utilization rate is lower, and further improvement is awaited.

SUMMERY OF THE UTILITY MODEL

To the current situation of above-mentioned prior art, the utility model aims to solve the technical problem that a collection supports, cooling, cold insulation and fire prevention function in an organic whole is provided, has both simplified the equipment process in order to improve production efficiency, has reduced the box under the function integrated type of volume in order to improve space utilization again.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a box under function integrated type, its characterized in that includes shell (1), core (2), snakelike liquid-cooled tube (4) and collection cold plate (5), the top opening part at shell (1) is transversely fixed in collection cold plate (5), the inside of shell (1) is located in core (2), but snakelike liquid-cooled tube (4) adopt the mode of heat conduction to fix on the lower plane of collection cold plate (5) and inlay and establish inside the upside of core (2), the upper and lower both sides of core (2) are all fixed respectively on the lower plane of collection cold plate (5) and the bottom of shell (1) through glue film (6).

Preferably, the upper side of the core material (2) is provided with a snake-shaped groove (2-1), the snake-shaped liquid cooling pipe (4) is embedded in the snake-shaped groove (2-1), and a sealing foaming glue (3) is filled between the snake-shaped groove (2-1) and the snake-shaped liquid cooling pipe (4).

Compared with the prior art, the utility model has the advantages of: the utility model discloses all fix core (2), snakelike liquid cooling pipe (4) and cold-proof board (5) inside so that box collection support, cooling, cold insulation and fire prevention function in an organic whole under shell (1), both simplified the equipment process in order to improve production efficiency, reduced the volume again in order to improve space utilization.

Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in figures 1-2, a box under function integrated type, including shell (1), core (2), snakelike liquid-cooled tube (4) and collection cold plate (5), the top opening part at shell (1) is transversely fixed in collection cold plate (5), the inside of shell (1) is located in core (2), but snakelike liquid-cooled tube (4) adopt the mode of heat conduction to fix on the lower plane of collection cold plate (5) and inlay and establish inside the upside of core (2), the upper and lower both sides of core (2) are all fixed respectively on the lower plane of collection cold plate (5) and the bottom of shell (1) through glue film (6).

The upper side of the core material (2) is provided with a snake-shaped groove (2-1), a snake-shaped liquid cooling pipe (4) is embedded in the snake-shaped groove (2-1), and a sealing foaming adhesive (3) is filled between the snake-shaped groove (2-1) and the snake-shaped liquid cooling pipe (4) to eliminate a gap.

The working principle is as follows: the lower box body is fixed below the battery pack, the upper plane of the cold collecting plate (5) is attached to the electric core of the battery pack, when the electric core generates heat, the heat of the electric core can be transferred to the cold collecting plate (5), at the moment, cooling liquid is introduced into the snake-shaped liquid cooling pipe (4) through one end of the snake-shaped liquid cooling pipe (4), and then flows outwards through the other end of the snake-shaped liquid cooling pipe (4) after flowing through the snake-shaped liquid cooling pipe (4), so that the heat on the cold collecting plate (5) is taken away to achieve a cooling effect; the core material (2) has a cold insulation function and a fireproof function, and the cold insulation function can prevent the cold quantity of the cooling liquid in the snake-shaped liquid cooling pipe (4) from being lost to the outside; the fire prevention function can prevent that flame from transmitting to on the battery package when externally burning to better protection battery package electricity core.

The utility model discloses all fix core (2), snakelike liquid cooling pipe (4) and cold-proof board (5) inside so that box collection support, cooling, cold insulation and fire prevention function in an organic whole under shell (1), both simplified the equipment process in order to improve production efficiency, reduced the volume again in order to improve space utilization.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
