Abstract
A method of manufacturing a cooling block for a battery module includes preparing a first cooling block and a second cooling block. The first cooling block is configured to be in contact with battery modules on a first side thereof. The second cooling block is configured to be bonded to a second side of the first cooling block and forms a cooling channel, through which cooling water can flow, at an interface with the second side of the first cooling block. The second cooling block is disposed and fixed on the second side of the prepared first cooling block with a jig. The fixed first cooling block and second cooling block are bonded by heating and welding the first and second cooling blocks. Only the second cooling block is selectively quenched.
