Method and device for indirect cooling of heat sources of a system component of a visualization system

A system component (2) of a visualization system (1), the system component (2) comprising:

• at least one heat source (14) generating waste heat during operation;
• wherein
• a housing (3) with an interior (4) in which the at least one heat source (14) is arranged and which is closed off to outside;
• and
• at least one cooling line (29) filled with coolant arranged in the interior (4), with which the at least one heat source (14) is coolable;
• a primary heat sink (15), an inner side (23) of which delimits the interior (4), the at least one cooling line (29) ends in each case at or in the primary heat sink (15);
• wherein the at least one cooling line (29) does not completely penetrate a wall (33) of the interior (4) into a surrounding area;
• the primary heat sink (15) is in contact on an outer side with external ambient air, and the inner side (23) of the primary heat sink (15) is arranged in the interior (4) and an outer side (22) of the primary heat sink (15) is arranged outside of the interior (4);
• a cooling tunnel (17), which has an inflow opening (20) for introducing ambient air and an outflow opening (21) for discharging the ambient air which has heated up at the primary heat sink (15), and the primary heat sink (15) is formed as part of the cooling tunnel (17);
• and
• wherein the cooling tunnel (17) is integrated into the housing (3) and extends through the interior (4) such that internal air in the interior of the housing flows around an outer side of the cooling tunnel (17) and the cooling tunnel (17) is surrounded in the housing by the internal air.

A method for indirectly cooling at least one heat source (14) of a system component (2) of a visualization system (1), the method comprising:

• closing off an interior (4) of the system component (2), in which at least one heat source (14) is arranged;
• generating an internal air circulation (16) that circulates only within the closed-off interior (4);
• and
• transporting waste heat via the internal air circulation (16) from the at least one heat source (14) to an inner side (23) of a primary heat sink (15), with the inner side (23) arranged in the interior (4);
• wherein the primary heat sink (15) forms part of a cooling tunnel (17), which has an inflow opening (20) for introducing ambient air and an outflow opening (21) for discharging the ambient air which has heated up at the primary heat sink (15), and the primary heat sink (15) is formed as part of the cooling tunnel (17);
• wherein the internal air circulation (16) is circulating in the interior (4) due to an air guide element (31);
• and
• the cooling tunnel (17) is integrated into the housing (3) and extends through the interior (4) such that the internal air circulation (16) flows around an outer side of the cooling tunnel (17) and the cooling tunnel (17) is completely surrounded by the internal air circulation (16) within the housing (4).

A method for indirectly cooling at least one heat source (14) of a system component (2) of a visualization system (1), the method comprising:

• closing off an interior (4) of the system component (2), in which at least one heat source (14) is arranged;
• removing waste heat from the at least one heat source (14) via a cooling line (29) filled with coolant only up to a primary heat sink (15);
• and
• removing the waste heat from the closed-off interior (4) to outside via the primary heat sink (15) using heat conduction;
• wherein the primary heat sink (15) forms part of a cooling tunnel (17), which has an inflow opening (20) for introducing ambient air and an outflow opening (21) for discharging the ambient air which has heated up at the primary heat sink (15), and the primary heat sink (15) is formed as part of the cooling tunnel (17);
• wherein the internal air circulation (16) is circulating in the interior (4) due to an air guide element (31);
• and
• the cooling tunnel (17) is integrated into the housing (3) and extends through the interior (4) such that the internal air circulation (16) flows around an outer side of the cooling tunnel (17) and the cooling tunnel (17) is completely surrounded by the internal air circulation (16) within the housing (4).
