The invention provides a heat exchanger structure of an electric automobile that is applied to the technical field of electric automobile batteries, one side of a first heat exchanger (11) of the electric automobile heat exchanger structure is communicated with a battery water path inlet (13), the other side of the first heat exchanger (11) is communicated with one side of a second heat exchanger (12), and the other side of the second heat exchanger (12) is communicated with a battery water path outlet (24). One side of the first heat exchanger (11) is communicated with a three-way water valve (5), the three-way water valve (5) is communicated with a warm air inlet (14) and a PTC water outlet (15), the other side of the first heat exchanger (11) is communicated with a warm air outlet (16) and a PTC water inlet (17), one side of the second heat exchanger (12) is communicated with a refrigerant inlet (18), and the other side of the second heat exchanger (12) is communicated with a refrigerant outlet (19). According to theheat exchanger structure, the purpose of heating or cooling the battery can be achieved according to needs, the working performance of the battery is improved, the service life of the battery is prolonged, and the structure of the whole heat exchanger is simplified.
Description
Technical field [0001] The present invention belongs to the technical field of electric vehicle batteries, and more specifically, it is related to an electric vehicle heat exchanger structure. Background technique [0002] In the low temperature environment (eg, -20 ° C), there are two aspects of the lithium ion power cell, one is low temperature, the battery discharge capacity is extremely poor, even if the full power condition, the driving ability of the vehicle will be greatly reduced; the other, Low temperature charging has been considered to be the fastest way to break the life of the power battery. At low temperatures, the conductivity of the electrical ion in the battery is poor, and the transfer and embedding ability of the charge in the negative electrode material structure are also poor. If the low temperature is charged, a large amount of lithium ion is deposited to the negative surface, and the electrons are deposited after electrons after electrons, forming a lithium...
