A heat exchanger. The heat exchanger comprises a plurality of primary fluid tubes configured to carry a primary fluid, a plurality of secondary fluid tubes configured to carry a secondary fluid, and a plurality of intervening layers, each intervening layer being thermally conductive and impermeable to both the primary and secondary fluids. Each intervening layer has one or more of the primary fluid tubes on a first side, and one or more of the secondary fluid tubes on a second side opposite the first side, such that the region between each pair of neighbouring intervening layers contains either primary fluid tubes or secondary fluid tubes, but not both primary and secondary fluid tubes.

A solvent heater for vehicular window washing solvent wherein the solvent heater is a vehicular exhaust pipe. There is a vessel having an inlet through which a washing fluid is received from a reservoir and an outlet through which the fluid is discharged for cleaning the window. There is a heating element for heating the fluid in the vessel, which element preheats the vessel before the washing fluid is received therein, whereby at least an initial quantity of the fluid is rapidly heated and discharged from the vessel.

A heat exchanger including a shell extending in a longitudinal direction D from a first end to a second end and including a mantle extending from the first end to the second end, and a solid inner core made of a core material and located inside the shell, the core extending in direction D from a first extremity towards the first end to a second extremity towards the second end. Whereby, at least one first flow path is provided inside the core, each first flow path extending from the first extremity to the second extremity of the core, n circuitous second flow paths extend through the core and/or between the core and the mantle, so that the at least one first flow path is surrounded by the n second flow paths over a non-zero rectilinear distance ΔL in direction D, n being an integer greater than 1.

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.

A heat exchanger (10) for a thermochemical biomass converter, the heat exchanger (10) comprises first and second conduits (12a, 12b) that are configured to carry, in use, process medium of the converter, and a heat transfer member (14) that thermally connects the first and second conduits (12a, 12b) to one another to define a heat transfer medium between the conduits (12a, 12b). The thermal expansion coefficient of the first and second conduits (12a, 12b) is matched to the thermal expansion coefficient of the heat transfer member (14) to continually provide thermal connection between the heat transfer member (14) and conduits (12a, 12b) under changing temperature conditions.

The present discloses a gas-gas high-temperature heat exchanger, including a shell (12), a tube sheet (5), a low-temperature gas inlet pipeline (6) and an outlet pipeline (7), and a high temperature gas outlet (8), the tube is divided into a first heat transfer zone (1) and a second heat transfer zone (2), a low temperature gas (4) flows in the tube, the tube includes a insert component (9) and an outer fin (10); a heat transfer tube in the second heat transfer zone (2) has a sleeve structure, a high-temperature gas (3) flows in the core tube (13), the low temperature gas (4) flows in an annular region between the core tube (13) and an outer tube (14), the high-temperature gas (3) flows out of the core tube (13) and flows into the shell-side area of the second heat transfer zone (2) again.

An adjustable, customizable, and configurable heat transfer element is structured for facilitating hear transfer in pipe systems having process pipes. The heat transfer element is configured for transferring heat between a process pipe and a corresponding tracer tube in order to maintain a fluid within the process pipe within a predetermined temperature range. In this regard, the heat transfer element may comprise a body having a nested portion that forms a cavity therein, each extending in a longitudinal direction. The body is configured for operative coupling to the process pipe. The cavity of the nested portion is configured to receive a tracer tube therein such that the tracer tube is positioned in between, and at least partially surrounded by the body and the process pipe. Moreover, the body may comprise a spine that is utilized to aid in bending the heat transfer element in one or more planes.
