The invention relates to the technical field of
electric cars, in particular to an integrated water-cooled
power battery box. The integrated water-cooled
power battery box provided by the invention comprises a box cover, a box body and a temperature regulating power
system, wherein the box body is made of an aluminum
alloy material and is manufactured by an
extrusion moulding technology; a circulating flow passage is formed in the wall of the box body; a circulating loop for a temperature regulating medium to flow circularly is arranged inside the wall of the box body; and the temperature regulating power
system can drive the temperature regulating medium to circularly flow in the circulating loop. In such a way, a
water cooling board and a battery box are designed in an integrated manner,a hollow aluminum
alloy section is adopted to achieve lightweight design, mechanical properties such as strength and rigidity are met, the integrated water-cooled
power battery box is simpler in structure, better in
technical performance and smaller in occupied space, and the comprehensive cost can be reduced; the heat-dissipating, cooling and temperature-raising and heating functions can be achieved by using one set of temperature regulating power
system, the integrated water-cooled power battery box is simpler in structure, more convenient and fast to use and smaller in occupied space, themanufacturing cost and the using cost can be reduced, and the heat-dissipating efficiency and the
heating efficiency can be improved.
