Planar heat exchanger body for plate-shaped photovoltaic solar module that is arranged on roof, has cooling passages formed in or outside base body by multi-stage gas or water injection molding process and/or laser or chipping process

摘要

The body (1) has integrated cooling passages (4) for cooling plate-shaped photovoltaic solar modules and arranged independent of each other, where the body is made of plastic or metal. The cooling passages are distributed in a meander-like manner on a planar base body. Multiple pipe unions (2) are arranged at side edges (8) of the body. The cooling passages are formed in or outside the base body by a multi-stage gas or water injection molding process and/or a laser or chipping process. Reinforcing ribs are arranged in a planar contact surface (3) of the body. Independent claims are also included for the following: (1) a method for manufacturing a heat exchanger body (2) a method for manufacturing a heat exchanger.
