A combo-cooler includes heat exchangers having parallel tubes corresponding to each heat exchanger aligned in a tube plane. A first end tank assembly includes a columnar end tank separated by a baffle into compartments each in fluid communication with a respective hydraulically independent fluid circuit. The second tank assembly includes manifolds aligned in a column. Serially adjacent manifolds are in slidable contact or separated by a respective gap to allow relative translation. Banks of the tubes are brazed in fluid communication with a compartment and a manifold to connect the compartment and the manifold to have a respective fluid flow therethrough. A bracket contacts at least two of the serially adjacent manifolds to prevent translation between the bracket and the serially adjacent manifolds perpendicular to the tube plane and to allow relative translation between the at least two of the serially adjacent manifolds parallel to the tubes.

The present invention relates to a method for braze-welding a fixing plate and a flow channel cap in a heat exchanger, and to a heat exchanger produced by same. The method includes: providing a fixing plate 10 having a plurality of resilient protrusions 11 for snap-fitting; providing a flow channel cap 20, one end 22 of which is L-shaped to be snap-fitted onto the resilient protrusion 11 and the other end of which has a stepped portion 21; inserting the stepped portion 21 of the flow channel cap 20 into the resilient protrusion 11 such that an end 21b of the stepped portion 21 contacts an end of the resilient protrusion 11; pressing the L-shaped end 22 of the flow channel cap 20 against the resilient protrusion 11 of the fixing plate 10 such that the L-shaped end 22 is snap-fitted onto the resilient protrusion 11 and thus tightly contacts the fixing plate 10, and the resilient protrusion 11 thus press-contacts the end 21b of the stepped portion 21 to enable an end 21a of the stepped portion 21 to tightly contact the fixing plate 10; and braze-welding the fixing plate 10 and the flow channel cap 20. The above-described method eliminates a spot-welding process which might otherwise be performed prior to the process of braze-welding the fixing plate and the flow channel cap in conventional heat exchangers, to thereby reduce manufacturing costs and labor and to improve productivity.

A phase change material container assembly for use in a thermal energy storage system. The container assembly includes a plurality of containers (plates, wedges . . . etc.) where the containers are generally flat and each approximating a segment of a ball or it may be a single device including features of a plurality of component containers as previously described. The components may be spherical segments, spherical wedges (ungula), hemispheres, spherical sectors, spherical caps or any combination. The plurality of containers are assembled to approximate a sphere's external perimeter. The plurality of containers are spaced apart to allow water, or other fluids, to flow between the plurality of containers.

A charge-air cooler for a fresh-air system of an internal combustion engine may include a cooler box and an upper shell such as a flange plate. The cooler box may include a cooler box passage opening, and the flange plate may include a flange plate passage opening arranged complementary with the cooler box passage opening. An adapter element may have a first end section and a second end section. The adapter element may be connected to a rim of the cooler box that borders the cooler box passage opening. A pipe element may be detachably secured to the adapter element and have a first end section and a second end section. The first end section of the adapter element and the first end section of the pipe element may define a clip-type connection when the adapter element and the pipe element are secured to one another.
