Heat exchanger

A heat exchanger comprising:

• a first tube/fin block having a first side and a second side that opposes the first side;
• the first tube/fin block having a first header arranged on the first side of the first tube/fin block and a second header arranged on the second side of the first tube/fin block, the first header and the second header of the first tube/fin block communicating with tubes of the first tube/fin block;
• and
• a second tube/fin block having a first side and a second side that opposes the first side;
• the second tube/fin block having a first header arranged on the first side of the second tube/fin block and a second header arranged on the second side of the second tube/fin block, the first header and the second header of the second tube/fin block communicating with tubes of the second tube/fin block,
• wherein the first tube/fin block with the first header and the second header of the first tube/fin block is an air-side cooled coolant cooler,
• wherein the second tube/fin block with the first header and the second header of the second tube/fin block is an air-side cooled refrigerant cooler,
• wherein the first header of the first tube/fin block and the first header of the second tube/fin block are both provided on a first side of the heat exchanger and are connected to one another, and the second header of the first tube/fin block and the second header of the second tube/fin block are both provided on a second side of the heat exchanger and are connected to one another, and
• wherein the second tube/fin block has a single inlet for receiving refrigerant, the single inlet being provided on the first header of the second tube/fin block,
• the heat exchanger further including a collector that is fluidly connected to the second tube/fin block,
• wherein the collector includes a single fluid outlet, the single fluid outlet of the collector being fluidly connected by a fluid connection to the single inlet of the second tube/fin block, such that refrigerant flowing out of the fluid outlet of the collector enters the first header of the second tube/fin block through the single inlet,
• wherein the collector includes the single fluid outlet, the single fluid outlet of the collector being fluidly connected by the fluid connection to the single inlet of the second tube/fin block, such that the refrigerant flows through a single fluid inlet of the collector into the collector, flows out of the collector through the single fluid outlet of the collector, flows from the single fluid outlet of the collector into the fluid connection and flows from the fluid connection into the single inlet of the second tube/fin block, and
• wherein the fluid connection is a fluid conveying block, a first surface of the fluid conveying block directly contacting an outer surface of the collector and a second surface of the fluid conveying block directly contacting an outer surface of the first header of the second tube/fin block, the first surface of the fluid conveying block being oriented perpendicular to the second surface of the fluid conveying block.
