Coldplate for use with a transformer in an electric vehicle (EV) or a hybrid-electric vehicle (HEV)

摘要

A coldplate for use with a transformer in an electric vehicle (EV) or a hybrid-electric vehicle (HEV). The coldplate includes a main portion having a recess formed therein, the recess having a floor configured for contacting a bottom surface of a transformer for dissipating heat generated by the transformer. The main portion includes a raised feature configured for contacting a winding of the transformer for dissipating heat generated by the transformer. The coldplate also includes a bracket member for use in securing the transformer in the recess of the main portion, the bracket member configured for contacting the main portion and the transformer for dissipating heat generated by the transformer. The bracket member includes a contact surface for contacting a top surface of the transformer, the contact surface having an area sufficient to contact substantially all of the top surface of the transformer.
