Structure is simple, low cost, safe and reliable, well cooling down and reaching temperature between each battery cell of inside battery can be realized
Uniformity.
It is an object of the invention to be achieved through the following technical solutions: a kind of electric automobile battery box, including upper box, nowel
Body and battery, the centre position of lower box height is provided with dividing plate, and dividing plate above and below is phase-change material and fills region, battery
The through dividing plate in hole, battery is by connection sheet arranged in series in battery hole, and the gap between battery hole is provided with heat pipe hole；Both sides
The upper box having air inlet and air outlet is located at lower box top, and upper box base plate has the heat identical with dividing plate size and location
Pore and battery hole；Being provided with heat pipe in heat pipe hole, radiating fin is placed on the first half of heat pipe；The top of upper box is provided with trapezoidal
Cover plate.
Described heat pipe is fixed by the heat pipe hole of dividing plate.
Described upper box and lower box be two in horizontal trapezium structure.
Described phase-change material is the mixture of paraffin and graphite, and wherein the mass percent of paraffin is 80%, the quality hundred of graphite
Mark is 20%.
Work process and the principle of the present invention be:
First, the heat absorption that battery is shed by the phase-change material filled in lower box, and keep the temperature between each battery equal
Even distribution, the heat pipe being intervally arranged by absorb heat in phase-change material be conducted to above fin, fin has and dissipates greatly
Hot side amasss, and utilizes air channel and blower fan constantly upper box zone line to be carried out forced-convection heat transfer in addition, and heat is by rectangle the most at last
Vent sheds.
Compared with prior art, the invention has the beneficial effects as follows:
One, the present invention fill phase-change material at battery ambient, phase-change material directly contact with battery case, beneficially the most direct and
Dispel the heat in the external world.
Two, the present invention has assigned heat-conductive thermo tube between phase-change material, and heat imports in heat pipe by the phase-change material of surrounding, logical
