Description

Shell of low-voltage horizontal auxiliary power supply system

Technical Field

The utility model belongs to the low voltage power supply field, concretely relates to horizontal lithium cell.

Background

The 12V auxiliary lithium battery mainly has the following functions: 1. providing electric energy when the vehicle is started; 2. when the vehicle is flamed out and parked, the power supply module supplies power to the constant-current module; 3. auxiliary discharge when the DC-DC output is insufficient; 4. providing electric energy for powering on a high-voltage system of the hybrid electric vehicle or the electric vehicle; 5. the 12V electrical device is powered prior to the HV being powered up. The shell of the lithium battery is mostly made of metal aluminum, the cost is high, and the processing difficulty of the aluminum alloy shell is high. Therefore, the price of lithium batteries is higher than that of common lead-acid batteries.

With the increasing shortage of energy, the improvement of economic benefit demand in industrial production and the continuous aggravation of air pollution, how to reduce the cost of lithium batteries makes lithium batteries replace lead-acid batteries become a problem to be solved urgently.

Disclosure of Invention

The utility model aims at overcoming the not enough in the above-mentioned technique, and provide a horizontal auxiliary power supply system's of low pressure shell, the casing adopts the lightweight design, and the quality is light, the radiating effect is good, practice thrift the cost.

The technical scheme of the utility model is that: the heat dissipation device comprises a shell, wherein reinforcing rib groups are uniformly distributed on the front surface and the back surface of the shell, each reinforcing rib group comprises a middle reinforcing rib positioned in the middle and an edge reinforcing rib connected to the periphery of the middle reinforcing rib, and the periphery of the middle reinforcing rib is connected with the edge reinforcing rib to form a grid-shaped heat dissipation structure; the middle reinforcing ribs comprise polygonal reinforcing ribs arranged in an array manner, and horizontal reinforcing ribs and vertical reinforcing ribs which are used for connecting the polygonal reinforcing ribs; the edge reinforcing ribs comprise a plurality of vertical section reinforcing ribs and a plurality of horizontal section reinforcing ribs.

The polygonal reinforcing rib is one of a square, a pentagon, a hexagon and an octagon.

And the upper end of the shell is provided with a concave spigot used for supporting the assembly of the plastic section.

The shell is made of PA66 engineering plastics.

The side surface of the shell is designed with a lower fixing position so as to meet the installation requirements of most of domestic host plants.

The casing is the open square tubular structure in upper end, and square tubular structure is enclosed by four lateral walls and diapire.

This casing surface is latticed heat radiation structure's strengthening rib group, when guaranteeing casing intensity, can reduce whole casing weight, still has good radiating effect simultaneously.

When this casing and plastic carrier assembly, the plastic carrier directly supports through the casing recess, removes and supports the epoxy board, realizes the lightweight design, has practiced thrift the cost, helps improving battery module's efficiency and energy density in groups simultaneously.

fig. 2 is an assembly schematic diagram of a soft-package battery cell and a shell.

Detailed Description

Taking a 12V light-weight horizontal auxiliary power supply system (12V auxiliary lithium battery for short) as an example for explanation,

exterior packaging (length, width, height): 237mm 180mm 70mm, the capacity is less than or equal to 20Ah, the volume is small, the weight is light, the lower fixing mode is adopted for the whole vehicle, and the CAN communication is adopted for the whole vehicle.

In fig. 1 and 2, after the upper cover 9 is covered on the shell 1, the upper cover is connected with the shell through 4M 4 screws arranged at four corners, and the auxiliary battery is detachable and low in after-sale maintenance cost.

Casing 1 is an uncovered square tube that encloses by four lateral walls and diapire, piles up by the parallel constitution of 4 square soft-packaged electrical core and organizes electric core module, and electric core module is installed in casing 1, bonds through two ingredient heat conduction glues and buffer material 3 between the adjacent soft-packaged electrical core, ensures that electric core after in groups links integratively, and the vibration resistance is strong, and buffer material 3 and heat conduction glue are insulating heat conduction material, can derive the heat of electric core module to play and connect the fixed action. The side of the housing 1 near the rear wall is designed with a lower fixing position 107. 201 is the top seal of the soft package battery core.

The front and back face walls of the shell 1 are evenly provided with a plurality of hexagonal reinforcing ribs 101, the hexagonal reinforcing ribs extend along the length direction and the width direction of the shell, and the hexagonal reinforcing ribs 101 are used for dissipating heat of the battery and can be used for enhancing the strength of the shell.

The hexagonal reinforcing ribs 101 are connected through the horizontal reinforcing ribs 103, the vertical reinforcing ribs 102, the vertical section reinforcing ribs 104 and the horizontal section reinforcing ribs 105 to form a grid-shaped heat dissipation structure.

During assembly, the plastic carrier is directly supported through the groove of the shell, and the support epoxy plate is removed, so that the lightweight design is realized.
