Document Type and Number:
Japanese Patent JP6477659
Kind Code:
B2
Abstract:
An inspection method for a heatsink according to the present disclosure includes a measurement preparation step of placing the heatsink in a place where radiated-heat quantities can be measured by first and second thermal sensors, each of the first and second thermal sensors including a temperature sensor and a heat-concentrating mirror with a heat-receiving surface curved in a concave shape, the first and second thermal sensors being disposed in different places in a state where a heat-receiving line is inclined from a direction in which the fin protrudes by a predetermined angle, a measurement step of acquiring first and second radiated-heat quantities from the first and second thermal sensors, respectively, and a determination step of determining that a coating state of the coating is fine when a total value of the first and second radiated-heat quantities is larger than a predetermined range defined in advance.
