Abstract
A cooling-abnormality detecting system in which a heat generating component and a cooling component contact each other via a contact section, and the cooling component cools the heat generating component. The cooling-abnormality detecting system includes: a heat-generating-component-temperature detecting sensor, a heat-generating-component-power-consumption detecting sensor, a cooling-component-temperature detecting sensor, and a processor that calculates a heat resistance value of the contact section between the heat generating component and the cooling component and determines the presence or absence of an abnormality in the contact section.
Claims13
A cooling-abnormality detecting system configured to perform abnormality detection for a cooling system, comprising:
- a heat generating component;
- a cooling component;
- a contact section, wherein the heat generating component and the cooling component come into contact with each other via the contact section which is sandwiched between and in direct contact with the cooling component and the heat generating component, and the cooling component is configured to perform heat radiation from the heat generating component;
- a heat-generating-component-temperature detecting sensor configured to detect a temperature of the heat generating component;
- a heat-generating-component-power-consumption detecting sensor configured to detect a power consumption value in the heat generating component;
- a cooling-component-temperature detecting sensor configured to detect a temperature of the cooling component, wherein the cooling-component-temperature detecting sensor is in direct contact with the cooling component;
- and
- a processor configured to, during standard operation mode of the heat generating component:
- calculate a heat resistance value of the contact section between the heat generating component and the cooling component using the temperature of the heat generating component, the temperature of the cooling component, and the power consumption value and output the heat resistance value, and
- determine presence or absence of an abnormality of the contact section between the heat generating component and the cooling component based on the heat resistance value.
