Abstract
Abstract A heat exchange device for air conditioners and the like comprising a primary body member of sheet plate material having tubular flow conduit fastened thereto for receiving and containing the flow of fluid such as the liquid/gas used with air conditioners and the like. Projecting pins securely attached to the plate member or members in single or double rows alternately with the tubing material provide the heat exchange improvement. Several different embodiments of the tubing and rows of projecting pins are provided for various type of applications. Another embodiment replaces the tubular flow conduit with a second plate member with the refrigerant flow being between the two plate members.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
205 words
In an air conditioning system including a compressor, a housing structure for said compressor, a condenser unit within the housing structure and having an air flow exit vent formed therein, a blower directing air from externally of the housing structure into the condenser unit, a cooling unit within the housing structure and having an air flow exit vent formed therein, an expansion apparatus associated with the cooling unit, and a blower directing air from externally of the housing structure into the cooling unit, the improvement comprising a first plate-like heat exchange and support member mounted in the condenser unit, a second plate-like heat exchange and support member mounted in the cooling unit, each of the members being disposed between the respective blowers in the units and the air flow exit vents formed therein such that the flow of air is directed into contact with the members, tube means for containing a refrigerant fluid secured to surface portions of each heat exchange and support member, and a plurality of pins projecting from a surface of each heat exchange and support member and being secured thereto, the pins extending from the surface of the heat exchange and support members into unobstructed contact with the flow of air.

Claim 3
Dependent Claim
142 words
The apparatus of claim 1 wherein the heat exchange and support members are contiguous to wall portions of the condenser unit and cooling unit except along the upper edge surfaces of the members and upper portions of the walls of the condenser unit and cooling unit, the openings forming a portion of air flow paths between the respective blowers and the respective air flow exit vents, and wherein the air flow exit vents in the condenser unit and cooling unit are formed in lower wall portions thereof, the pins projecting from the surface of each heat exchange and support member which is opposite to the respective blower and which is facing the respective air flow exit vent, the pins thereby lying directly in the flow path of the air as the air moves between each blower and each air flow exit vent.
