Problems solved by technology

[0006] In traditional methods, the process of forming castings is complicated because two parts should be manufactured and then joined to each other by mechanical coupling schemes
Also, if the interior of the casting is defective or the gasket is damaged, it can cause leaks, whereby water can seep into the power semiconductors
If this happens, it could cause a malfunction of the related system and possibly cause the vehicle to catch fire

Abstract

A method of forming a casting with a flow passage may include filling a tubular pipe with a filler to form a smart core; inserting the smart core into a mold having a cavity corresponding to a shape of the casting to be formed; injecting a molten metal into the cavity through a casting process; and removing the filler from the smart core, wherein a hardness of the tubular pipe is 70 Hv or more.

Description

technical field [0001] Exemplary embodiments of the present disclosure relate to a method of forming a casting, and more particularly, to a method of forming a casting having a runner and a casting formed by the method. Background technique [0002] Recently, as the development of electric vehicles, hybrid vehicles has become more active, various power conversion components such as drive motors, inverters, and converters have replaced conventional components of internal combustion engines such as engines and transmissions. [0003] Compared with conventional components, such power conversion components generate a large amount of heat in the process of charging and converting electric power into power to be used. [0004] Therefore, like other components that generate a lot of heat, power conversion components necessarily require flow channels for cooling. [0005] Such as figure 1 As shown, in the conventional technique, in order to form a runner in a part produced by a ca...
