Auxiliary heat exchanger having fluid retention member for evaporative cooling
View Patent ↗An auxiliary heat exchanger may reduce a temperature of a refrigerant allowed to pass through the auxiliary heat exchanger. The operation of the auxiliary heat exchanger may be controlled. In some implementations, the auxiliary heat exchangers may include fluid retention members, thermoelectric coolers, and/or other types of heat exchangers.
1. A system comprising:
an auxiliary heat exchanger comprising:
a housing, the housing comprising a rectangular cube open at two ends and comprising;
a first surface comprising an inner surface of the housing and comprising one or more fluid retention members coupled to at least a portion of the first surface of the housing; and
a second surface comprising an outer surface of the housing and distal to the one or more fluid retention members;
wherein the housing is configured to receive a flow of air through an interior of the housing, the flow of air able to remove heat from the first surface and the one or more fluid retention members; and
a refrigerant conduit coupled to a portion of the second surface that is distal to the first surface, the refrigerant conduit comprising an inlet and an outlet to the auxiliary heat exchanger and a flow path from the inlet to the outlet;
wherein a temperature of at least a part of refrigerant in the refrigerant conduit is reduced by heat transfer from the part of the refrigerant to at least one of the fluid retention members.
2. The system of claim 1 wherein the auxiliary heat exchanger further comprises a condensate line coupled to at least one of the fluid retention members.
3. The system of claim 1 wherein the auxiliary heat exchanger further comprises a container coupled to at least one of an evaporator or a water line, and wherein a fluid leaving the container flows to at least one of the fluid retention members.
4. The system of claim 3 wherein the container automatically allows fluid to flow from the water line into the container when a fluid level in the container is less than a predetermined fluid level.
5. The system of claim 1 further comprising an air conditioner, wherein the air conditioner comprises a switch, and wherein the switch controls the operation of the auxiliary heat exchanger.
6. The system of claim 1 wherein at least one of the fluid retention members comprises channels configured to retain fluid at least partially in the channels, and wherein air flows proximate the channels, and wherein the air at least partially evaporates the fluid at least partially retained in the channels to reduce a temperature of at least a part of the refrigerant.
