Embodiment Construction
[0047]The present invention provides a control method and a control device for controlling the start and stop of a water-cooling heat dissipation fan. Fine control of the cooling fan.
[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0049] In a specific embodiment of the present invention, the control method for controlling the start and stop of the water cooling fan includes the following steps:
[0050] S101: Determine whether the start commands of the first water-cooling fan and the second water-coolin...

The invention discloses a control method and device for controlling start and stop of water-cooling heat dissipation fans. When start commands of the first water-cooling heat dissipation fan and the second water-cooling heat dissipation fan are not both one, the work time t1 of the first water-cooling heat dissipation fan and the work time t2 of the second water-cooling heat dissipation fan are compared firstly, whether the first water-cooling heat dissipation fan or the second water-cooling heat dissipation fan is about to run is decided according to the comparison result, meanwhile, the work time of the water-cooling heat dissipation fan is accumulated, and accordingly the work time of the two water-cooling heat dissipation fans can be balanced. Due to the fact that the work time of the two water-cooling heat dissipation fans is compared before a decision is made on which water-cooling heat dissipation fan runs, refined control over the first water-cooling heat dissipation fan and the second water-cooling heat dissipation fan can be achieved.
Description
technical field [0001] The present invention relates to the field of control of a water-cooling fan, and more specifically, relates to a control method and a control device for controlling the start and stop of a water-cooling fan. Background technique [0002] As the power level of wind power converters increases, more and more fan converters start to use water cooling for heat dissipation. When the power level of the water-cooling radiator is large, it will be equipped with multiple cooling fans. At present, the control of water-cooling cooling fans is generally It is started according to the water temperature. When the water temperature reaches the starting temperature of the first water cooling fan, the first water cooling fan is started. When the water temperature is lower than the stop temperature of the first water cooling fan, the first water cooling fan is stopped; when the water temperature reaches the second water cooling fan When the starting temperature of the c...
