In one aspect of the present disclosure, an indirect heat exchanger pressure vessel is provided that includes an inlet header to receive a pressurized working fluid, such as water, glycol, ammonia, and/or CO.sub.2. The indirect heat exchanger pressure vessel includes an outlet header to collect the pressurized working fluid and a serpentine circuit tube connecting the inlet and outlet headers. The serpentine circuit tube permits the pressurized working fluid to flow from the inlet header to the outlet header. The serpentine circuit tube includes runs and a return bend connecting the runs. The return bend has a controlled wrinkled portion comprising alternating ridges and grooves. The alternating ridges and grooves strengthen the return bend and permit the indirect heat exchanger pressure vessel to facilitate working fluid heat transfer at a high internal operating pressure.

A flat tube with a wall made of a shaped first sheet metal strip which forms two fluid chambers, wherein the two fluid chambers are arranged spaced apart from one another and wherein the two fluid chambers are connected spaced apart from one another by a web wherein the flat tube has two tube ends in its tube longitudinal direction, wherein the web has a recess by means of a cutout at at least one tube end.

A support and connection device is for an operating group of a vehicle. The support and connection device is configured for supporting and for fluidic connection with an operating device in turn included in the operating group. The support and connection device identifies a vertical axis and two longitudinal axes and includes at least one plate-shaped unit in which, in the vertical direction, there is at least one mouth for the passage of a working fluid. The plate-shaped unit includes an upper laminar element, a lower laminar element reciprocally stacked along the vertical axis and a hollow space between them. The at least one mouth for fluid passage is defined laterally by a fluid mouth wall constituted by the reciprocal engagement of an upper mouth rim included in the upper laminar element and by a lower mouth rim included in the lower laminar element.

Methods and systems are provided for a heat exchanger for a motorized vehicle. In one example, a heat exchanger includes a plurality of tubes coupled to a header, with each tube including a partition extending a height of the tube. The partition includes a notch positioned at an end of the tube coupled to the header, with the notch extending into the tube.

Examples of the disclosure relate to an oscillating heat pipe comprising for cooling components within a bendable electronic device. The oscillating heat pipe comprises at least one condenser region to be positioned in a first portion of the bendable electronic device and at least one evaporator region to be positioned in a second portion of the bendable electronic device. The oscillating heat pipe also comprises at least one bendable region provided between the condenser region and the evaporator region and configured to extend across a hinge of a bendable electronic device wherein at least one bendable region comprises a polymer tubing supported by a flexible helical support structure.

A vapor chamber with a support structure and its manufacturing method are provided. The vapor chamber with the support structure includes a first plate, a second plate spaced apart from the first plate, and multiple support elements fixed between the first and second plates. On an outer surface of any of the first plate or the second plate, laser welding is performed on positions corresponding to the support elements so as to join the support elements to the first and second plates and to form weld ports on the outer surface of any of the plates. The invention solves the problem of fixing the support structure inside the thin vapor chamber, and therefore mass production can be realized.

A radiator for cooling a transformer, preferably a power transformer, or a choke, includes a plurality of plate-shaped radiator elements which are disposed parallel to one another and through which a coolant can flow in parallel. At least one elastically deformable element is provided at least between two adjacent radiator elements and is constructed in such a way that it counteracts an expansion of the radiator elements perpendicular to the surface of the radiator elements. Plastic deformation of the walls of the radiator elements can be prevented by the elastically deformable elements. A unit including a transformer or a choke and a method for producing a radiator are also provided.

A heat transfer member reinforcement structure includes a main body. The main body has a first side, a second side and a reinforcement member. The reinforcement member is selectively disposed between the first and second sides or inlaid in a sink formed on the first side. The reinforcement member is connected with the main body to enhance the structural strength of the main body.

There is disclosed a heat exchanger comprising at least one set of channels having a proximal end and a distal end, the set of channels comprising: a first channel defined by a first skin and a wall; and a second channel defined by a second skin and the wall, wherein the wall located between the first channel and the second channel comprises a first at least one aperture to allow fluid to pass through the wall from the first channel to the second channel.

A heat exchanger (100) having a plurality of plates (101) manufactured preferably but not limiting to the stamping process, the plates has been configured to accommodate the internal fins (106). The plates (101) also define plurality of the passages (102) for flowing at least two fluids. A plurality of conduits (103) fluidly coupled to a first end and second of the end of the plates (101) which allows the flow of the fluids. At least one inlet (104) coupled to a first end, and at least one outlet (105) coupled to the second end of the plurality of plates (101) configured to allow the flow of the fluids wherein each fluid flow in a different direction from the other, a plurality of inner fins (106) disposed on a surface of each of the plurality of plates (101) for increasing the surface to volume ratio of the first and second fluid to achieve pre-defined thermal performance.
