Heat exchanger for battery

Abstract

The invention relates to a heat exchanger for a battery. The heat exchanger comprises cooling plates, water jackets and a turbulence generation unit, wherein the cooling plates are respectively arranged between every two adjacent battery units; the water jackets are arranged at the at least one sides of the two sides of the cooling plates, a plurality of supply holes used for supplying a refrigerant are formed in the lower side faces of the water jackets, and a plurality of discharge holes are formed in the upper side faces of the water jackets; the discharge holes are connected with the supply holes of another stacked water jacket so as to supply the refrigerant for the side of another water jacket; the turbulence generation unit is used for bending the refrigerant poured into the supply holes of the water jackets. The heat exchanger is capable of generating turbulent flow in the water jackets by using the turbulence generation unit.

Description

technical field [0001] The present invention relates to a heat exchanger for a battery, and more specifically, to a heat exchanger for a battery that cools heat generated from a plurality of stacked battery cells by the heat exchanger. Background technique [0002] Generally speaking, an electric vehicle or a hybrid vehicle is operated by using electricity charged in a battery, and it has gradually become popular as it is classified as an environmentally friendly vehicle due to high oil prices and environmental improvement. trend. [0003] Such an electric vehicle or a hybrid vehicle has an advantage of low maintenance cost based on the use of electric power of an installed battery, but also has the disadvantage of short durability of the battery, which is expensive compared to other components. [0004] In particular, the performance and durability of such a battery are determined by temperature, and if the heat generated during use cannot be effectively cooled, the electr...

Problems solved by technology

[0015] However, the battery cooling device according to this prior art has the disadvantage of being difficult to manufacture because the turbulators 7 are formed with irregular surfaces to generate turbulent flow.

[0016] Moreover, in order to fix the turbulence device 7 on the water jacket 3, it is necessary to use a plurality of sealing covers 9 of separate parts, and thus there are disadvantages of additional manufacturing of the sealing cover 9 and an increase in the assembly process.

[0017] In particular, in order to fix the turbulator 7 to the water jacket 3, there is a disadvantage that an additional processing step of separately processing the insertion hole 8 in the water jacket 3 is required.

[0018] This shortcoming reflects the shortcoming of increasing the overall production cost of the battery heat exchanger and increasing the labor cost.
