Battery housing part, battery module, and method for producing a battery housing part

A method for producing a battery housing part (11), the method comprising the steps of:

• -providing a housing main body (18) having the battery housing part (11), the battery housing part (11) having a cooling channel (12) with a cooling channel bottom (13), a cooling channel wall (14) for delimiting the cooling channel (12), and flow-disturbing elements (15) for disturbing a coolant flow in the cooling channel (12), the flow-disturbing elements (15) projecting in a height direction (21) in a projection-like manner from the cooling channel bottom (13), wherein a part of the flow-disturbing elements (15) is configured in a form of normal elements (15a) and another part of the flow-disturbing elements (15) is configured in a form of supporting elements (15b), the supporting elements (15b) being configured to be higher than the normal elements (15a) in the height direction (21), and the supporting elements (15b) configured to be higher than the cooling channel wall (14) in the height direction (21), and
• removing end portions (20) of the supporting elements (15b) so that the height of the supporting elements (15b), in order to support a covering member (19) for covering the cooling channel (12), is equal to the height of the cooling channel wall (14) in the height direction (21).
