Embodiment Construction

[0028] The present invention will be further described below with reference to the drawings and specific embodiments, but the protection scope of the present invention is not limited to this.

[0029] Such as figure 1 As shown, the high-power density power battery cooling system of the present invention includes a single heat dissipation module and a heat dissipation base 1. The single heat dissipation module includes a power battery 2 and a cooling jacket 3. The power battery 2 is installed in the cooling jacket In 3, the cooling jacket 3 is provided with a cooling runner 31, which can be inside the cooling jacket 3 or on its inner and outer surfaces. Such as image 3 with Figure 4 As shown, the cooling channel 31 cools the inside of the jacket 3. Such as Figure 5 As shown, the bottom of the cooling channel 31 is provided with an inlet 311 and an outlet 312; the inlet 311 and the outlet 312 may be one each, or more than one may be designed as required. A number of the single ...

Abstract

The invention provides a high-power density power battery cooling system. The system comprises simplicial heat dissipation modules and a heat dissipation base, each simplicial heat dissipation modulecomprises a power battery and a cooling sleeve, each power battery is arranged in the corresponding cooling sleeve, and each cooling sleeve is internally provided with a spiral cooling channel; the bottom of each cooling channel is provided with an inlet and an outlet; the simplicial heat dissipation modules are regularly arranged on the heat dissipation base; the heat dissipation base is internally provided with a plurality of water inlet conduits and a plurality of water outlet conduits; any water inlet conduit is communicated with the inlet of at least one cooling channel, and any water outlet conduit is communicated with the outlet of at least one cooling channel. The high-power density power battery cooling system has the advantages that it can be achieved that the power batteries arecooled more fully and evenly and the temperature of each battery is controlled.

Description

Technical field [0001] The present invention relates to the power battery cooling field or the battery cooling technical field or the electric vehicle technical field, in particular to a high-power density power battery cooling system. Background technique [0002] The core of the power battery cooling system is how to maintain the battery as a whole in an appropriate temperature range, and to ensure the uniform temperature between the battery cells themselves and the batteries in the battery pack. Due to the limitation of the energy density of power batteries at this stage, the power density of the battery pack has not yet reached a satisfactory level. Compared with traditional fuel vehicles, the performance of electric vehicles still has a gap, mainly due to the range, charging time and battery cycle life. limits. At present, the technological development trend of power batteries is high energy density and long life cycle. The increasing energy density is bound to increase th...
