AI Technical Summary
Technical Problem
Conventional methods for manufacturing cooling blocks for vehicle battery packs often result in welding defects, leading to leaks and potential fires due to cooling water leakage, compromising watertightness and equipment safety.
Method used
A laser hybrid welding method is employed to join the upper and lower plates of the cooling block, ensuring defect-free welding and forming a watertight seal, using laser hybrid welding to integrate the plates into a single body.
Benefits of technology
Ensures watertightness and prevents fires or equipment failures by eliminating cooling water leaks through defect-free welding, enhancing safety and reliability of the cooling system.

Abstract
The present invention relates to a method for manufacturing a cooling block for a vehicle battery pack and a cooling block for a vehicle battery pack manufactured by the method. The method for manufacturing a cooling block for a vehicle battery pack according to the present invention comprises: a cooling block upper plate preparation step for preparing a cooling block upper plate, which is one side of the vehicle battery pack cooling block; a cooling block lower plate preparation step for preparing a cooling block lower plate to be welded and integrated with the cooling block upper plate; a cooling block upper plate and a cooling block lower plate contact surface arrangement step for arranging the cooling block upper plate and the cooling block lower plate so that a cooling water flow path is formed between the cooling block upper plate and the cooling block lower plate, through which cooling water flows; a welding position selection step for selecting a welding position between the cooling block upper plate and the cooling block lower plate arranged in contact surfaces; and a laser hybrid welding step for performing welding through a predetermined laser hybrid welding along the selected welding position so that the cooling block upper plate and the cooling block lower plate are integrated into a single body.
