Abstract
A first temperature value indicating a temperature near a heat source, a second temperature value indicating a temperature near an outer end of a cooling rib extending from the heat source, and a third temperature value indicating an ambient temperature in the location of the heat source are used to determine fouling status.
Claims20
A computer-implemented method comprising:
- receiving a first temperature value indicating a temperature near a heat source, a second temperature value indicating a temperature near an outer end of a cooling rib extending from the heat source, and a third temperature value indicating an ambient temperature in the location of the heat source;
- determining, using at least the received first, second and third temperature values, a convection rate indicator value;
- determining, using the convection rate indicator value, fouling status of cooling ribs cooling the heat source;
- and
- triggering a maintenance alert when the fouling status is dirty.
2 more elements
An arrangement comprising at least:
- a heat source;
- a plurality of cooling ribs, extending from the heat source, arranged to cool the heat source;
- a first temperature sensor near the heat source to measure first temperature values;
- a second temperature sensor near an outer end of a cooling rib, at a distance from the first temperature sensor to measure second temperature values;
- an ambient air temperature sensor to measure third temperature values in an environment at a location the heat source is;
- and
- a fouling status determination unit configured to obtain the first temperature values, the second temperature values and the third temperature values to determine fouling status of the cooling ribs.
4 more elements
An apparatus comprising:
- at least one interface configured to receive a first temperature value indicating a temperature near a heat source, a second temperature value indicating a temperature near an outer end of a cooling rib extending from the heat source, and a third temperature value indicating an ambient temperature in the location of the heat source;
- at least one processor;
- and
- at least one memory storing instructions,
- wherein the at least one memory and the instructions configure, with the at least one processor, the apparatus at least to:
- determine, using at least the received first, second and third temperature values, a convection rate indicator value;
- determine, using the convection rate indicator value, fouling status of cooling ribs cooling the heat source;
- and
- trigger a maintenance alert when the fouling status is dirty.
