Description

technical field [0001] The present application relates to the field of size detection systems for heat dissipation components, in particular to a size detection system and method for heat sinks. Background technique [0002] The heat sink is a device for dissipating heat from electronic components that are prone to heat in electrical appliances. It is mostly made of aluminum alloy, brass or bronze into plates, sheets, and multi-sheets. The contact surface of the heat sink is coated with a layer of heat-conducting silicone grease, so that the heat emitted by the components is more effectively transmitted to the heat sink, and then dissipated into the surrounding air through the heat sink. [0003] A heat source is usually installed at the bottom of the heat sink, and the heat is transferred to the surroundings through the upper fins. The size of the fin interval and the included angle affect the performance of the heat sink. For example, if the fin interval is large, the fin ...

Problems solved by technology

[0003] A heat source is usually installed at the bottom of the heat sink, and the heat is transferred to the surroundings through the upper fins. The size of the fin interval and the included angle affect the performance of the heat sink. For example, if the fin interval is large, the fin width will be reduced. The number of fins affects the heat dissipation effect; if the fin spacing is small, the heat is concentrated, and the heat dissipation effect cannot be greatly improved, resulting in a waste of energy; the angle between two adjacent fins usually also has certain requirements, and the size of the angle will affect the heat transfer to fin tip capacity

[0004] In the prior art, there is no specific detection system and method for the size of the heat sink, which leads to the direct use of the heat sink after manufacture. For heat sinks with unqualified sizes, the heat dissipation efficiency cannot be optimized, and there will be a waste of energy.
