Abstract
The invention relates to a mouth organ passageway parallel-flow type heat exchanger which is simple and reasonable in structure, capable of enlarging the effective heat exchange area and improving the heat exchange efficiency, good in heat exchange effect, easy to install and connect and convenient to assemble. The aluminum product structure is adopted, and therefore the weight is light; NOCOLOK soldering is adopted and therefore the welding quality is good, and the structure is reliable. Refrigerating fluid is selected as a medium, and therefore a cooling system of an electric vehicle is simplified. The heat exchanger comprises an upper throttling pipe and a lower throttling pipe. The throttling pipe is connected with a water inlet pipeline and a water outlet pipeline. Plugging covers are arranged at the two ends of each throttling pipe respectively. A plurality of heat dissipation pipelines are arranged between the upper throttling pipe and the lower throttling pipe and are multi-passageway pipelines. The sections of the heat dissipation pipelines are each in a flat mouth organ shape.
Description
technical field [0001] The utility model relates to the thermal management system field of an electric vehicle, and in particular relates to a harmonica channel parallel flow heat exchanger. Background technique [0002] A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a higher fluid to a lower temperature fluid, making the fluid The temperature reaches the index specified by the process. [0003] Battery packs in electric vehicles require thermal management devices (heat exchangers) to ensure their performance, durability and safety. Performance can be compromised at low temperatures, while durability can be compromised at high temperatures. [0004] Chinese patent: CN204142045U discloses a heat exchanger, including [0005] The first liquid chamber and the second liquid chamber; a plurality of flat through pipes communicating the first liquid chamber and the sec...
