A multi-pass heat exchanger having a return manifold with a partition, a front wall, and a rear wall is provided. The partition separates the return manifold into a collection chamber and a distribution chamber. The front and rear walls define a fluid channel. The front wall has a plurality of perforations placing the fluid channel in separate fluid communication with the collection chamber and the distribution chamber.

Multi-pass heat exchangers having return manifolds with distributing inserts

A heat exchanger assembly includes a first single-piece manifold and a second single-piece manifold spaced from and parallel to the first single-piece manifold. Each of the first and second single-piece manifolds has a tubular wall defining a flow path. A plurality of flow tubes extend in parallel between the first and second single-piece manifolds and are in fluid communication with the flow paths. An insert having a distribution surface is slidably disposed in the flow path of the first single-piece manifold to establish a distribution chamber within the first single-piece manifold. A series of orifices defined in the distribution surface of the insert are in fluid communication with the flow path and the distribution chamber for uniformly distributing a heat exchange fluid between the flow path and the flow tubes.

Heat exchanger assembly

A core unit for a heat exchanger comprises a pair of headers spaced from one another each defining a fluid space for receiving a fluid therein and each defining a plurality of apertures. A first region comprising a plurality of first tubes extends between the headers and a first fin is disposed between adjacent pairs of the first tubes. A second region comprising a plurality of second tubes extends between the headers and a second fin is disposed between adjacent pairs of the second tubes. A crushable center different than the first and second regions is disposed parallelly between the first and second regions for controllably crushing when the headers are bent.

An integrated electrical generator/starter and air conditioning compressor device driven by a common drive shaft, or other direct linkage. The device includes an electrical generator/starter and a compressor. The electrical generator/starter is coupled to the drive shaft. The compressor is coupled to the electrical generator/starter and to the drive shaft and acts to pressurize a flow of refrigerant in response to rotation of the drive shaft. The electrical generator/starter is operable in first and second states. In the first state, the electrical generator/starter generates electricity in response to rotation of the drive shaft. In the second state, the electrical generator/starter utilizes electrical power from a battery to rotate the drive shaft.

An assembly is provided to increase the efficiency of a vehicle engine cooling and supplementary, heat pump type cabin heating system. A flexible panel located in front of and below the front end heat exchanger can be moved between open and blocking positions. An engine cooling radiator and fan are located behind the front end heat exchanger. In cold weather heating mode, the flexible panel can be rolled to the blocking position, preventing the direct flow of cold outside ram air through the front end heat exchanger. At the same time, the fan is reversed, flowing heated air from the radiator through the front end heat exchanger, improving its efficiency.

Vehicle front end air control

An air conditioning system for a passenger compartment of a motor vehicle comprises a first heat exchanger (,) positionable outside the passenger compartment; a second heat exchanger (,) positionable inside the passenger compartment; a first fluid passage (,) between the first and second heat exchangers; a second fluid passage (,) between the first and second heat exchangers; an expansion device (,) positioned in the first fluid passage; an accumulator/dryer (,) fluidly connected with the second fluid passage; an electronically controlled variable stroke compressor (,) for pumping fluid into the second fluid passage and either in a first direction (X) sequentially through the first heat exchanger, the expansion device, the second heat exchanger and the accumulator/dryer, or in a second direction (Y) sequentially through the second heat exchanger, the expansion device, the first heat exchanger and the accumulator/dryer; reverse flow means (,) in the second fluid passage for controlling the direction of the flow of fluid; sensing means (,) providing an output signal dependent on one or more sensed conditions; and control means (,) electrically connected to the sensing means and to the compressor for receiving the output signal from the sensing means and for controlling the stroke of the compressor dependent on the output signal during fluid flow in the second direction. Provides precise control of compressor operation for improved control of passenger compartment heating.
