Abstract
A reversible flow heat exchange system includes a heat exchanger system that includes a canister configured to receive a first fluid from a machine and a heat exchanger disposed within the canister. The reversible flow heat exchange system also includes a cooling system coupled to the heat exchanger and configured to circulate a second fluid between the heat exchanger system and the cooling system and a reversing valve coupled to the heat exchanger and configured to selectively direct a flow of the first fluid in a first direction through the canister and in a second direction through the canister that is opposite the first direction.
Claims20
A reversible flow heat exchange system, the reversible flow heat exchange system comprising:
- a heat exchanger system comprising:
- a canister configured to receive a first fluid from a machine;
- and
- a heat exchanger disposed within the canister;
- a cooling system coupled to the heat exchanger and configured to circulate a second fluid between the heat exchanger system and the cooling system;
- a reversing valve positioned in-line between a plurality of fluid lines and coupled to the heat exchanger and configured to direct a flow of the first fluid in a first direction through the canister, wherein rotating the reversing valve 90° to the right directs the flow of the first fluid in a second direction through the canister that is opposite the first direction;
- and
- wherein the first fluid flows in the first direction for a first time interval and flows in the second direction for a second time interval, wherein the first and second time intervals depend upon a type of the first fluid used in the reversible flow heat exchange system.
A method of controlling a direction of fluid flow through a heat exchanger system, the method comprising:
- circulating a first fluid between a machine and the heat exchanger system;
- circulating a second fluid between the heat exchanger system and a cooling system;
- directing a flow of the first fluid through the heat exchanger system in a first direction by orienting a reversing valve in a first orientation and directing the flow of the first fluid through the heat exchanger system in a second direction by rotating the reversing valve 90° to the right;
- exchanging, via a heat exchanger of the heat exchanger system, heat between the first fluid and the second fluid;
- wherein a direction of flow of the first fluid through the machine remains the same when the first fluid flows through the heat exchanger system in the first or the second directions;
- and
- wherein the first fluid flows in the first direction for a first time interval and flows in the second direction for a second time interval, wherein the first and second time intervals depend upon a type of the first fluid used in the heat exchanger system.
A reversible flow heat exchange system, the reversible flow heat exchange system comprising:
- a heat exchanger system comprising:
- a canister configured to receive a first fluid from a machine;
- and
- a heat exchanger disposed within the canister;
- a cooling system coupled to the heat exchanger system and configured to circulate a second fluid between the heat exchanger system and the cooling system;
- a reversing valve positioned in-line between a plurality of fluid lines and coupled to the heat exchanger and configured to direct a flow of the first fluid in a first direction through the canister, wherein rotating the reversing valve 90° to the right directs the flow of the first fluid in a second direction through the canister that is opposite the first direction;
- wherein the first fluid flows in the first direction for a first time interval and flows in the second direction for a second time interval, wherein the first and second time intervals depend upon a type of the first fluid used in the reversible flow heat exchange system;
- an actuator coupled to the reversing valve and configured to control an orientation of the reversing valve;
- a controller configured to operate the actuator;
- and
- a sensor coupled to the controller and positioned to monitor build up of particulate matter on the heat exchanger.
