Embodiment Construction
[0047] The invention provides a battery heat management system based on phase change material and air coupling cooling, which solves the problems of low thermal conductivity of the phase change material in the cooling of the phase change material, leakage when the phase change material is melted and heat cannot be quickly discharged.
[0048] Phase change materials undergo a phase change near their phase change temperature, releasing or absorbing a large amount of heat. This feature of phase change materials can be used to store energy or control the ambient temperature, and has application value in many fields. Phase change materials have the characteristics of a wide range of applications, such as building energy saving, modern agricultural greenhouses, solar energy utilization, refrigeration and transportation of biomedical products and food, physical medicine (hyperthermia), heat dissipation of electronic equipment, cooling (warmth) clothing for athletes, Special temperatur...

Abstract
The invention discloses a phase-change material and air-coupled cooling-based battery heat management system, and aims at solving the problems that a phase-change material in phase-change material cooling is low in heat conductivity coefficient, and leaks when melted, and heat cannot be quickly discharged. The phase-change material and air-coupled cooling-based battery heat management system comprises battery cells (202), phase-change composite boards (203), radiators (204) and a battery box body (205), wherein the battery cells (202), the phase-change composite boards (203) and the radiators (204) form heat dissipation units; a pair of phase-change composite boards (203) and a pair of radiators (204) are symmetrically attached to the left part and the right part of each battery cell (202) in sequence; N heat dissipation units are transversely arranged and accommodated into a hollow cavity of the battery box body (205), and N is a natural number; and each phase-change composite board (203) comprises a support board body and a thermal conducting filler thereof.
Description
technical field [0001] The invention relates to a power battery heat management device, in particular to a battery heat management system based on phase change materials and air-coupled cooling. Background technique [0002] With the rapid development of social economy and science and technology, energy and environmental issues have become two major problems for human beings. Traditional fuel vehicles have large primary energy consumption, low efficiency and large pollutant emissions, which have posed a great threat to the energy and environmental fields of society. Electric vehicles have the advantages of zero consumption of primary energy and zero discharge of pollutants and have emerged as the times require. But electric vehicles also have a fatal shortcoming: during rapid charging and discharging, the battery generates a lot of heat. If the heat cannot be removed in time, the temperature of the battery will rise, and if the battery temperature is too high, the efficien...
