Patent number: 9581369Abstract: An evaporator configured to transfer heat between air flowing through the evaporator and refrigerant within the evaporator, and transfer heat between the refrigerant within the evaporator and phase change material (PCM) within the evaporator. The evaporator includes a first plate, a second plate, and a first tube. The second plate is coupled to the first plate to form an assembly that defines a cavity to contain PCM. The assembly also defines a first opening that cooperates with corresponding first openings in other assemblies to define a first manifold to convey refrigerant. The first manifold is defined when the assembly is arranged with the other assemblies to form a stack. The first tube is in fluidic communication with the first manifold. The assembly cooperates with an adjacent assembly of the other assemblies when the stack is formed to define a first slot configured to receive the first tube.Type: GrantFiled: December 10, 2014Date of Patent: February 28, 2017Assignee: MAHLE International GmbHInventors: Gary S. Vreeland, Scott B. Lipa

Patent number: 9518768Abstract: An evaporator having a phase change material clam shell housing is provided. The evaporator includes an upper manifold, a plurality of refrigerant tubes extending from the manifold, and a louvered clam shell housing defining a chamber for storing a phase change material. The louvered clam shell housing is disposed between and in thermal communication with the upper portion of two adjacent refrigerant tubes. The louvered clam shell housing is formed of two clam shell plates, each having louvers defined by slats folded into the phase change chamber. The folded slats define louver openings in the clam shell housing enabling the phase change material to make direct contact with the adjacent refrigerant tubes, thereby improving thermal communication between the refrigerant flowing in the tubes and the phase change material in the clam shell housing.Type: GrantFiled: September 6, 2013Date of Patent: December 13, 2016Assignee: MAHLE International GmbHInventors: Gary S.

Patent number: 9494350Abstract: A plate-type heat exchanger having a first heat exchanger portion configured to receive a refrigerant flow and a hot side coolant flow having a lower temperature than the refrigerant flow, a second heat exchanger portion configured to receive the refrigerant flow exiting from the first heat exchanger portion and a cold side coolant flow having a higher temperature than the refrigerant flow exiting from the first heat exchanger portion, and an internal heat exchanger portion sandwiched between the first heat exchanger portion and the second heat exchanger portion. The refrigerant flow through the plate type heat exchanger is in non-contact thermal communication with the hot side coolant flow and the cold side coolant flow. The cold side coolant flow transfers heat energy to the refrigerant, which in turn transfer that heat energy to the hot side coolant flow.Type: GrantFiled: June 5, 2014Date of Patent: November 15, 2016Assignee: MAHLE International GmbHInventors: Prasad S.

Patent number: 5332032Abstract: An automotive air conditioning system evaporator of laminated construction has tube plates, which, in brazed pairs, make up the individual flow tubes, that have an additional feature to assure regular, evenly spaced stacking of the tube plates prior to final assembly. Integrally stamped cups on one end of the plates nest to hold the cup end of the plates apart a defined distance when the plates are stacked. Spacer flanges on the opposite end of the plates interfit to keep the completed tubes spaced apart sufficiently to accommodate cooling fins in the final evaporator, but, without more, do nothing to keep the flange end of the plates evenly stacked. Special projections added to the spacer flanges contact edges of the spacer flanges of consecutive plates in the stack to keep the plates evenly spaced at both ends.Type: GrantFiled: October 12, 1993Date of Patent: July 26, 1994Assignee: General Motors CorporationInventors: David W.
