1Temperature
If narrow heat-sink flow channels are used to increase heat dissipation efficiency, then heat transfer performance is improved, but flow resistance increases and clogging becomes more likely
Solution Approach 1:
The flow channel system is segmented into two distinct types: narrow heat-sink flow channels for efficient heat transfer and wide side-flow channels for particle diversion. Each channel type performs a specialized function, allowing the system to simultaneously achieve high heat dissipation efficiency while maintaining reliability by preventing clogging through the parallel side-flow channels
Solution Approach 2:
The side-flow channels act as intermediary pathways that intercept and divert particles before they can enter and block the narrow heat-sink flow channels. This intermediary structure protects the critical heat transfer channels from contamination while maintaining the narrow channel geometry needed for efficient heat dissipation
2Area of stationary object
If thin fins are used to increase heat transfer surface area, then heat dissipation is improved, but flow channels become narrower and more prone to clogging
Solution Approach 1:
The cooling component's flow channel system is segmented into narrow heat-sink flow channels bounded by thin fins for maximum heat transfer surface area, and parallel wide side-flow channels that serve as protective pathways. This segmentation allows thin fins to be used effectively while the side-flow channels prevent particle accumulation and clogging in the heat transfer channels
Solution Approach 2:
The side-flow channels function as intermediary structures that capture and redirect particles away from the narrow heat-sink flow channels. This allows the system to maintain thin fin geometries for high surface area heat transfer while protecting against the harmful effect of particle clogging through the intermediary side-flow pathways
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly reduces flow resistance and prevents clogging, enhancing the efficiency and effectiveness of the cooling component.
Implementation Method 1
a metallic heat sink, i.e., a heat sink made of metal or a metal alloy (where applicable, coated) with a flat heat absorption side formed by a cooling surface... should be placed on a (for example, also planned) heat emission side of the object to be cooled... The heat sink then absorbs the waste heat of the object to be cooled
Implementation Method 2
the cooling medium flows inside the cooling component through the heat-sink structures of the cooling zones... which, in turn, is then dissipated by the cooling medium

AI summary
A cooling component for dissipating heat from objects to be cooled comprises cooling zones each with a heat-sink structure as a component of a heat sink of the cooling component, a fin or pin structure comprising fins or pins spaced at equal distances as well as heat-sink flow channels delimited by adjacent fins or pins, through which cooling medium can flow in parallel, which can be supplied to the cooling component via an inlet of the cooling component and which can be discharged from it via an outlet of the cooling component. At least one of the cooling zones comprises, in addition to its heat-sink flow channels, at least one side-flow channel connected in parallel to these heat-sink flow channels for reducing flow resistance or for passing through particles contained in the cooling medium.
