Embodiment Construction

[0017] Such as Figure 2 to Figure 5 As shown, in the embodiment of the present invention, a plurality of battery modules are stacked to form a battery pack with a heat dissipation structure. The battery pack is mainly provided with four heat sinks 30 and four spacer sleeves between the two battery modules 201 and 202. 40, and then pass through the aforementioned components through four screw rods 50 to form a combination.

[0018] The battery modules 201, 202 are a plurality of individual batteries 21 electrically connected together through metal connecting pieces 211, and then installed in a rectangular frame 22. The individual batteries 21 have a common output terminal 23, as mentioned above Two corresponding faces of the frame 22 are defined as an inner face 24 and an outer face 25, and two corresponding sides of the frame 22 are defined as a left side 26 and a right side 27, and a side of each individual battery 21 is defined from the described The inner surface 24 of th...

Abstract

The invention discloses a heat radiation structure aggregate cell superimposed by multiple cell modules. The aggregate cell is mainly formed by arranging heat radiation pieces and spacing sleeves between two cell modules and carrying out penetrating combination through screws. The heat radiation pieces can respectively and directly contact with one cell module and conduct heat to heat radiation fin surfaces, and the cooling is realized by contacting fins of the heat radiation fin surfaces with air. A spatial distance between two cell modules of the aggregate cell can avoid a heat accumulation problem caused by the direct contact of the two cell modules and can form a hollow heat radiation channel, and the hollow heat radiation channel which allows cold air at the outside of the aggregate cell with hot air in the heat radiation channel to be smoothly exchanged makes the aggregate cell be cooled. According to the screw design of the aggregate cell of the invention, the number of the cell module can be easily expanded to achieve the use convenience.

Description

technical field [0001] The invention relates to a collection battery formed by stacking a plurality of battery modules. Background technique [0002] For the actual demand for high-output batteries, in the battery industry, a large number of individual batteries are connected in series or in parallel to form a collection battery with high output power. [0003] In the above-mentioned collective battery with high output power, each individual battery inside the collective battery will release heat during the process of charging and discharging, resulting in a rise in temperature. The aforementioned temperature rise of the battery will cause the battery to fail to operate normally and safely. Such as figure 1 As shown, the U.S. Patent Publication No. US2007 / 0037051 is a collection battery 10 structure, which is mainly provided with a spacer 12 between each individual battery 11, and a plurality of concave-convex structures 13 on one side surface of the spacer 12 make the Ea...
