A number of flat tubes, flat tube heat exchangers, and methods of manufacturing both are described and illustrated. The flat tubes can be constructed of one, two, or more pieces of sheet material. A profiled insert integral with the flat tube or constructed from another sheet of material can be used to define multiple flow channels through the flat tube. The flat tubes can be constructed of relatively thin material, and can be reinforced with folds of the flat tube material and/or of an insert in areas subject to higher pressure and thermal stresses. Also, the relatively thin flat tube material can have a corrosion layer enabling the material to resist failure due to corrosion. Heat exchangers having such flat tubes connected to collection tubes are also disclosed, as are manners in which such tubes can be provided with fins.

Flat tube, flat tube heat exchanger, and method of manufacturing same

A method for producing tubes for use in a heat exchanger that includes providing first and second metallic strips on a rolling mill train with predetermined breaking points using a device, deforming the strips to form the a tube, separating individual tubes from the tube at the predetermined breaking points, sensing positions of the predetermined breaking points in the strips using a sensing element which the strips pass through, transmitting signals relating to sensed positions of the predetermined breaking points of the strips to a computer, comparing the positions of the predetermined breaking points in the first and the second strips using the computer on the basis of the signals transmitted, and sending signals to the device using the computer which lead to the alignment of the positions of the predetermined breaking points in the first and the second strips.

Method of producing tubes and a rolling mill train for producing tubes

A system and method for producing flat tubes is described and illustrated. The flat tubes can be produced from at least one strip of endless band material having at least one wall part and an inner part formed with corrugations on a roller train provided with roller pairs, with the strip running in a longitudinal direction through the rollers and being shaped. The inner part of the flat tube can be formed with corrugations placed between the shaped wall parts, after which the closure of the flat tube is carried out. Production of the flat tubes can include forming spaced apart band thinning lines running in the longitudinal direction of the strip, and forming corrugation peaks and corrugation troughs at the band thinning lines.

Tubes and method and apparatus for producing tubes

A coolant system includes a heat exchange circuit capable of being in a heat exchange relationship with a heat generating component, such as an engine, to remove thermal energy from the engine and transfer the thermal energy to a coolant, and an insulated tank in fluid communication with the heat exchange circuit. The system also includes a control and associated conduits and valves for passing coolant through the heat exchange circuit and the insulated tank so as to fill the tank with a first volume of coolant in a first operational state, for passing an additional amount of coolant from the heat exchange circuit into the insulated tank so as to fill the insulated tank with a second volume of coolant which is greater than the first volume of coolant in a second operational state, and for passing the additional amount of coolant from the insulated tank to the heat exchange circuit in a third operational state. A method of operating the coolant system to store thermal energy is also provided.

Coolant system with thermal energy storage and method of operating same

A cooling system includes a radial fan rotatable by an axis to deliver radial air flow to the cooling system, a plurality of heat exchangers spaced radially from the fan and arranged around the fan in a box-like configuration to receive the radial air flow therefrom, with the heat exchangers bounding an interior space of the cooling system. One of the heat exchangers is provided in the form of a charge air cooler that includes a first flow path for a charge air flow in heat exchange relation with a second flow path for an engine coolant flow of the vehicle. The cooling system further includes a surface associated with the charge air cooler to substantially block the radial air flow from exiting the interior space through the charge air cooler.

Box-like cooling system

A compact cooling system includes a mounting panel adapted to receive a plurality of at least three cooling units, a cooling fan, and a fan drive mechanism. The mounting panel supports the fan and drive mechanism in a manner allowing rotation of the fan about the axis of rotation. A front side of the mounting panel is adapted for receiving and supporting the cooling units in a pattern defining a cantilevered, tubular polygonal solid disposed about the fan. The mounting panel includes a convex central region extending into the tubular polygonal solid and receiving the drive mechanism in operative connection to the fan. By virtue of this arrangement, a very compact cooling system is provided. The tubular polygonal shape of the cooling units, when mounted on the mounting panel, forms an air duct for directing a flow of cooling air induced by the fan through the cooling units. Positioning the drive mechanism inside the convex central region of the mounting panel significantly reduces the length of the cooling system along the axis of rotation.

Compact cooling system

Optimization of the efficiency of a compact cooling system for air cooling of at least two different heat exchange fluids is obtained in a construction including three heat exchangers ( ), ( ), ( ) arranged in a housing-like shape with an open center. A radial fan ( ) is located within the housing and is rotatable about an axis ( ). A front panel ( ) having an air inlet ( ) on the axis ( ) abuts a corresponding one of the opposed sides ( ), ( ) of each of the heat exchangers while a rear panel abuts the other of the opposed sides ( ) of each of the heat exchangers ( ), ( ), ( ) and journals the fan ( ) for rotation about the axis ( ). The assembly is characterized by the fact that the core width &ldquo;W &rdquo; of one of the heat exchangers ( ) is greater than that of another of the heat exchangers ( ) such that one or both of the opposed sides ( ), ( ) of the one heat exchanger projects forwardly and/or rearwardly of a corresponding one or both of the opposed sides ( ), ( ) of the heat exchanger ( ).

Cooling system, especially for a vehicle

A heat exchanger including a first header having an inlet therein, a second header, an outlet in one of the first and second headers, and a plurality of flat tubes extending between the first and second headers for carrying a fluid between the first and second headers. A first connector is also provided for connecting a first exterior line to one of the first and second headers, the first connector being proximate and substantially parallel to an end of one of the flat tubes. In a compact cooling system, such heat exchangers may be disposed about a radial fan directing air flow outwardly away from the fan axis. One of a system inlet and a system outlet are connected via the first exterior lines to the first connectors of at least two of the heat exchangers.

Compact heat exchanger for a compact cooling system

A compact cooling system including a radial fan directing air flow outwardly and a plurality of heat exchangers disposed around the radial fan. Each heat exchanger has a plurality of tubes extending between an inlet header and an outlet header, with the headers extending generally in the same direction as the fan axis. A system inlet is connected to the inlet headers and a system outlet is connected to the outlet headers, whereby the length of the connection between each heat exchanger and the system outlet and system inlet is generally the same for each heat exchanger.
