A low volume, high capacity latent heat storage device is achieved in a construction including a salt case () with an optional outer jacket () surrounding the salt case () in spaced relation thereto to define an insulating space () between the two. Inlet and outlet conduits (), (), (), (), extend from the exterior of the outer jacket () to the interior of the salt case () and at least one tube () is located within the salt case and has a plurality of straight, parallel runs () defining a matrix with an exterior and a phase change material is sealed within the tube (). The tube runs () inwardly of the matrix exterior are in a regular or equilateral polygonal pattern with each run () abutting a plurality of adjacent runs () and each run () at the exterior of the matrix additionally engaging the salt jacket (). The runs () have cross-sectional shapes such that flow spaces (, () exist between the runs () and between the salt jacket () as well between adjacent runs (). The flow spaces (), () are in fluid communication with the inlet and outlet conduits (), (), (), ().

Latent heat storage device

An elongate manifold construction ( ) having an longitudinal axis ( ) is provided for use in a heat exchanger ( ) having a plurality of tubes ( ). The manifold construction ( ) includes an elongated tank piece ( ) and an elongated header piece ( ). A plurality of embossed beads ( ) having openings ( ) therein that are engaged by tabs ( ) spaced along the longitudinal axis ( ) to maintain the tank and header pieces ( ) in proper alignment with each other so as to obtain a suitable bond joint therebetween during a bonding operation.

Manifold for heat exchanger

A heat exchanger provides simplicity, compactness, and high efficiency through a construction that includes an elongated tube structure comprising three rows of flattened multiport tubing, with a first row of tubing and a third row of tubing sandwiching a second row of tubing . The second row of tubing terminates in opposite ends on which are received refrigerant fittings and respectively. The first and third rows of tubing each include a run abutting and in heat exchange relation with the tubing . Opposing ends of the tubing extend about refrigerant fittings and and are received in refrigerant fittings . The tubing includes parts and extending about the refrigerant fittings and and terminating in opposite ends . The ends are also in fluid communication with fittings

Heat exchanger header construction

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.

Heat battery

A tube having a plurality of hydraulically parallel fluid passages for use in a heat exchanger can be made by forming an elongated, undulating insert and disposing the same within a flattened tube. A noncorrosive brazing flux is adhered to at least one of the interior of the tube and the crests on the undulating insert. Braze alloy is also located at the interface of the crests of the insert and the interior wall of the tube. Thereafter, the insert is located within the tube without disturbing the flux and the tube deformed along its length to bring the interior of the tube into contact with the crests on the insert. The assembled tube and insert construction is then heated to braze joints between the interior wall of the tube and the crests of the insert along the entire length of the latter.

Method of making a heat exchanger

A tank-header connection including a groove extending about the periphery of a header plate and having a bottom wall surrounded by an upstanding wall with spaced apertures therein. A compressible gasket is located in the groove and a plastic tank having an opening surrounded by a rim is provided. The rim has a series of outwardly projecting lugs and is otherwise sized and configured to fit within the groove with the lugs extending through and being captured in aligned ones of the apertures.
