Abstract
Various systems and methods are provided for cooling a cabinet. In one embodiment, a method is provided that comprises the steps of controlling a speed of the at least one cooling fan in response to a temperature of the cabinet, and, controlling the speed of the at least one cooling fan in response to a position of an access panel relative to the cabinet.
Claims16
A method for cooling a cabinet, comprising:
- controlling a speed of the at least one cooling fan in the cabinet in response to a temperature of the cabinet;
- and
- controlling the speed of the at least one cooling fan in response to a position of an access panel relative to the cabinet.
A system for cooling a cabinet, comprising:
- at least one cooling fan;
- means for controlling a speed of the at least one cooling fan in response to a temperature of the cabinet;
- and
- means for controlling the speed of the at least one cooling fan in response to a position of an access panel relative to the cabinet.
1 more element
A system for cooling a cabinet, comprising:
- at least one cooling fan;
- a fan speed controller electrically coupled to the at least one cooling fan, the fan speed controller comprising a processor circuit having a processor and a memory;
- an intrusion sensor electrically coupled to the fan speed controller;
- and
- speed control logic stored in the memory and executable by the processor, the speed control logic comprising logic that causes a maximum drive signal to be applied to the at least one cooling fan to drive the at least one cooling fan at a maximum speed upon receipt of a signal from the intrusion sensor that indicates that an access panel on the cabinet is open.
2 more elements
A system for cooling a cabinet, comprising:
- at least one cooling fan;
- an intrusion sensor electrically coupled to the at least one cooling fan and operatively coupled to an access panel of the cabinet, wherein the intrusion sensor applies a maximum drive signal to the at least one cooling fan that drives the cooling fan at a maximum speed in response to an opening of the access panel;
- and
- at least one temperature sensor electrically coupled to the at least one cooling fan.
1 more element
A system for cooling a cabinet, comprising:
- at least one cooling fan;
- a fan speed controller electrically coupled to the at least one cooling fan, the fan speed controller comprising a processor circuit having a processor and a memory;
- at least one temperature sensor electrically coupled to the fan speed controller;
- speed control logic stored in the memory and executable by the processor, the speed control logic comprising logic that causes a first drive signal to be applied to the at least one cooling fan in response to a signal received from the at least one temperature sensor, the first drive signal driving the at least one cooling fan at a predefined speed;
- and
- an intrusion sensor electrically coupled to the at least one cooling fan, the intrusion sensor applying a second drive signal to the at least one cooling fan that drives the at least one cooling fan at a maximum speed, wherein the second drive signal overrides the first drive signal.
