A method of constructing a coil wound heat exchange module and transporting and installing the coil wound heat exchange module at a plant site, such as an natural gas liquefaction plant. A module frame is constructed and attached to a heat exchanger shell prior to telescoping of a coil wound mandrel into the shell. The module frame includes a lug and two saddles that remain attached to the shell throughout the process and when the heat exchanger is operated. The lug and saddles are constructed and located to stabilize the shell during construction, telescoping and transport (when in a horizontal orientation), and when the shell is installed at the plant site (in a vertical orientation). The lugs and saddles are adapted to allow for thermal expansion and contraction of the shell when it is transitioned from ambient to operating temperature and vice versa.

The invention relates to a method for producing a heat exchanger (1) having tubes (2), which are each received at the longitudinal end side in an associated header (3), wherein the tubes (2) and the headers (3) are formed out of aluminium and are soldered to one another and, in a state soldered to one another, form a coolant-conducting channel structure (4).

Here it is substantial for the invention that the heat exchanger (1), following the soldering of the tubes (2) to the headers (3), is cold-formed and the strength thereby increased.

By way of this, the weight and the costs can be reduced and the performance and the strength increased.

A heat exchanger is characterized by having two or more fluid flow circuits, each formed by multiple small cross-section “micro-tubes” contained within a surrounding metal structure, or “metal matrix.” Its function is to efficiently transfer heat from one fluid to another in a highly compact assembly. Most any metal or metal alloy can be considered for the micro-tubes. The micro-tubes, while typically arranged in alternating layers of alternating flow circuits, may be organized in any number of arrangements including co-linear and at cross angles to provide for co-flow, counter flow and cross flow. The metal matrix, is provided in one embodiment by a metal or metal alloy powder consolidated in a hot isostatic pressing (HIP) process. This process also joins the tubes together and to the matrix itself, producing a monolithic structure.

The present disclosure relates to atomizers for an aerosol delivery device such as a smoking article. The atomizer may include a liquid transport element and a wire extending along at least a portion of a longitudinal length thereof. The wire may define contact portions configured to engage heater terminals and a heating portion configured to produce heat. The heating portion may include a variable coil spacing. In other atomizers, the wire may extend at least partially through the liquid transport element proximate the contact portions. Related inputs, cartridges, aerosol production assemblies, and methods of forming atomizers are also provided.

A method of forming a heat exchanger tube, particularly suited for condensing applications, contemplates cold-rolling a metallic strip to emboss a hydrophobic surface texture, to thereby form an embossed surface on the metallic strip. The method includes roll forming the metallic strip to a tubular shape, with the embossed surface on the exterior of the tubular shape, and welding the edges of the roll-formed strip to form a heat exchanger tube. Cold-rolling to emboss a hydrophobic surface texture exhibiting a contact angle of at least about 75° is contemplated, with processing including heat-treatment to minimize degradation of the hydrophobic surface texture, and roll-forming to avoid deformation of the hydrophobic surface texture,

A method for forming heatsink tube includes cutting a base sheet plate into a first molded frame and a second molded frame, applying a flux on an inner face of the first molded frame and the second molded frame, mounting the first molded frame on a heatsink fin module, and mounting the second molded frame on the first molded frame, to assemble the first molded frame, the heatsink fin module, and the second molded frame, and to form a heatsink tube. The first molded frame has a first end faceplate and two first connecting portions. The second molded frame has a second end faceplate and two second connecting portions. Each of the two first connecting portions is formed with a first abutting section, and each of the two second connecting portions is formed with a second abutting section.
