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

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 highly efficient heat exchanger susceptible of a variety of uses is provided by a construction including first and second spaced, parallel headers 10, 12, 114 and 140 and a plurality of substantially identical serpentine conduits 18, 104 having at least three generally parallel runs 24, 105 and terminating in opposed ends 20, 22, 106, 108; 130, 132. The conduits 18, 104 are in generally spaced, side-by-side relation. One end 104 of each conduit 18, 104 extends to and is in fluid communication with the first header 10, 114, 140 and the other end of each conduit 18, 104 extends to and is in fluid communication with the second header 12. A plurality of serpentine fin sheets 30, 120 are located so as to extend between an associated pair of the conduits 18 in thermally conducive relation therewith.

Serpentine fin, round tube heat exchanger

A combination radiator and oil cooler including a elongated tubular header 10 having a generally cylindrical cross section with an interior 14 defining a liquid side and an exterior 22 defining an air side. A plurality of elongated parallel tubes 12 are joined to the header 10 at one side thereof and fins 16 extended between the tubes 12. A saddle element 24 is disposed on the header 10 oppositely of the tubes 12 and has a periphery 28, 56, joined to the exterior 22 and an internal section 30, 58, bounded by the periphery 28, 56 and spaced from the exterior 22 to define an oil space 32, 60. An inlet fixture 34 and an outlet fixture 36 are secured to the saddle element 24 oppositely of the space 26, 60 and within the periphery 28, 56 in fluid communication with the oil space 26, 60.

Radiator and oil cooler

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

Improved resistance to pressure caused deformation in header and tank construction utilized in heat exchangers is achieved by providing domes, preferably exteriorally convex, in the header surfaces of the header and tank construction. These domes are located in the area between the holes in such constructions through which tubes extend.
