Abstract

The invention provides a harmonica channel type heat exchanger, aiming at solving the problems that for a pure electric vehicle and a serial hybrid electric vehicle, an air heat exchanger difficultly meets a battery heat management effect. The harmonica channel type heat exchanger is characterized by comprising a plurality of groups of heat radiation assemblies which are arrayed in parallel at intervals, wherein each heat radiation assembly comprises a first current collector, a second current collector, and a water cooling plate for communicating the first current collector and the second current collector; the first current collector is provided with two water pipe connectors; the first current collector of the heat radiation assembly at one side is connected with a water inlet pipe, and the first current collector of the heat radiation assembly at the other side is connected with a water outlet pipe; the first current collectors of all the heat radiation assemblies are communicated with each other by a middle water pipe; batteries are arranged at the two sides of the water cooling plates of each heat radiation assembly; and the batteries and the water cooling plates are clamped and firmly fitted. The harmonica channel type heat exchanger has the advantages that the heat radiation assemblies are arrayed in parallel at intervals, and are clamped and firmly fitted with the batteries, so that the water cooling effect is realized; the structure is relatively simple and compact and the cost is low, the heat-exchanging coefficients are relatively high, the cooling and heating speed is rapid, the safety performance is high and the effect is relatively good.

Description

technical field [0001] The invention relates to the field of heat management systems for electric vehicles, in particular to a harmonica channel heat exchanger. Background technique [0002] At present, batteries for electric vehicles mainly include lead-acid batteries, nickel-hydrogen batteries and lithium-ion batteries. Relevant studies have shown that the life of lead-acid batteries decreases linearly with the increase of temperature, but the charging efficiency increases linearly, because as the battery temperature decreases, the charge acceptance capacity decreases, especially below 0°C, the temperature gradient between modules reduces the entire battery life. The capacity of the battery pack needs to maintain the uniform distribution of the temperature in the battery pack and control the temperature between 35~40°C. The efficiency and maximum operating power of the electric vehicle increase in the range of -26~65°C. The performance of nickel-hydrogen batteries is also...
