Abstract
In a refrigerated beverage dispenser having a plurality of coplanar circular cooling plates closing the bottoms of an array of beverage bowls, each concentric turn of a single multi-turn sinuous coiling of evaporator tubing is bonded in intimate heat-exchange relationships with all of the cooling plates and directs flow of the refrigerant serially across and part way around each cooling plate, and back, in succession. Tubing which interconnects across the spaces between adjacent cooling plates is clustered, to promote maximum arcuate spanning of the plates by those more active portions of the tubing best disposed to provide the cooling.
Claims7
A beverage dispenser, comprising a stand housing a refrigeration system, a plurality of cooling members mounted on said stand with first surfaces oriented to transfer heat away from beverage in bowls on said stand, said cooling members all having second surfaces opposite said first surfaces in heat-transferring engagements with one evaporator in said refrigeration system, said evaporator having a single refrigerant passageway therethrough in the general form of a single multi-turn elongated loop with coplanar concentric turns, the sucessive passageway turns in said loop each coursing substantially arcuately about at least part of each of said cooling members, in succession, and then similarly coursing back across said cooling members in the opposite sequence to complete each turn in said loop, whereby to promote uniformly in cooling by said members.
A multi-bowl beverage dispenser, comprising a stand housing a refrigeration system, a plurality of spaced-apart substantially circular cooling plates exposed atop said stand in position to transfer heat away from beverage in bowl compartments disposed above said stand, all of said plates having lower surfaces which are substantially coplanar with one another and which are united in heat-transferring engagements with one evaporator in said refrigeration system, said evaporator having a refrigerant passageway therethrough in the general form of a single multi-turn flat loop which is elongated in direction of lateral spreading of said spaced-apart plates, the successive passageway turns in said loop each being substantially concentric and coursing substantially arcuately about at least part of each of said cooling plates, in succession, and then similarly coursing back across said cooling members in the opposite sequence to complete each turn in said loop, whereby to promote uniformity in the chilling of beverages in all the bowl compartments by said cooling plates.
