Abstract
A heat exchanger including a housing having a base and defining an interior. A plurality of coils are located in the interior of the housing and are arranged to extend upwardly from the base to define a coil depth. A blower is adapted to move air through the plurality of coils in a direction of the coil depth. A water distribution system is preferably located around a circumferential periphery of the plurality of coils to spray water on an outer surface of the plurality of coils along substantially the entire coil depth thereof. At least one air inlet opening is located in the housing to allow airflow across the plurality of coils. Additional embodiments of improved heat exchangers are disclosed herein.
Claims17
A heat exchanger comprising:
- a housing having a base and defining an interior;
- a plurality of coils located in the interior of the housing and arranged to extend upwardly from the base to define a coil depth;
- a blower adapted to move air through the plurality of coils in a direction of the coil depth;
- a water distribution system to spray water onto the plurality of coils, wherein the water distribution system is located around a circumferential periphery of the plurality of coils to spray water on an outer surface of the plurality of coils along the entire coil depth thereof;
- at least one air inlet opening located in the housing to allow airflow across the plurality of coils;
- a coil alignment mechanism located on the base for positioning the plurality of coils thereon, the number of the plurality of coils being adjustable so that a desired amount of cooling is provided by the heat exchanger;
- and
- the coil alignment mechanism comprises a plurality of posts which extend generally upwardly from the base, and each of the plurality of coils is connected to the plurality of posts using a sliding engagement.
