A tube for a heat exchanger includes a tube outer body enclosing a tube inner volume, and a corrugated insert received within the tube inner volume. The tube outer body has a pair of broad planar walls joined by arcuate end walls. The corrugated insert defines flow channels through the tube, with opening in flanks of the insert allowing for flow communication between adjacent flow channels. Bypass channels adjacent the arcuate end walls are fluidly isolated from the adjacent flow channels by the absence of such openings in the end flanks. Flow through the bypass channels is obstructed by flow blocks at one or both ends of the bypass channels.

Tube for a heat exchanger, and method of making the same

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 heat exchanger with a plurality of stacked flat tubes and a collecting tank having a wall extending around the entire periphery of, and connected to, the end of the stacked flat tubes. A first medium may be distributed through the collecting tank and flat tubes. Internal inserts are in the flat tubes, with the inserts being bonded between the broad sides of the tubes and, in the region of connection of the tubes to the collecting tank, being configured to compensate for length changes in the stacking direction caused by temperature changes, as by recesses in connectors such as wave flanks or by corrugated wave flanks. The flat tubes with inserts such as described may be separately provided for use in manufacture of heat exchangers.

Heat exchanger with flat tubes

An economically manufactured heat exchanger is provided and includes a plurality of elongated, straight, flat tubes (), each formed of two identical halves () joined to each other in mirror image fashion and each having opposed open ends and all arranged in a stack (). At least one spacer wall () is disposed within each tube and extends generally from end to end thereof to define at least two side-by-side first fluid flow paths within a tube. An elongated housing () contains the stack and includes spaced headers () with each header including a tube slot for the adjacent end of each tube () in the stack (). Spacers () in the stack separate adjacent tubes in the stack from one another and the spacers include ribs defining a serpentine flow path for a second fluid. An opening () is located in the housing () near each end thereof and is in fluid communication with the second fluid flow path ().

Heat exchanger

Venting difficulties in a heat battery including a first container (10) for housing a heat storage salt that may be in the solid phase or in the liquid phase, a heat exchanger (22) within the container (10) and a second container (12) surrounding the first container (10) in generally spaced relation to provide an insulating space (14) about the first container (10) along with coolant inlet and outlet connections (40, 42) to the heat exchanger (22) are avoided in a vent system (52) including a vent inlet (66) generally centrally located in the top wall (56) of the first container (10) generally centrally of the ends thereof. A vent passage includes a check valve (106) located in close proximity to the vent opening (66) and the vent opening is surrounded by a cup shaped baffle (60) having an opening (62) facing the interior of the container (10). A filter (78) is located between the check valve (106) and the opening (62) to the baffle (60). The check valve (106) is located in a valve housing (104) which itself serves as a safety valve to vent pressure in the event the check valve (106) malfunctions.
