Apparatus for rapid heating of a liquid including a heat source, a liquid flowpath defining element defining a liquid heating flowpath therein having a liquid inlet and a liquid outlet, a collection of flexible elongate thermal conductors located within the flowpath, the collection of flexible elongate thermal conductor portions being thermally coupled to the heat source and defining multiple liquid heating passageways through the flowpath whose configurations and cross-sectional dimensions change over time, thereby being resistant to clogging.

Systems and methods are disclosed for conditioning a fuel gas for a gas engine of a multi-stage gas compressor. The system includes a scrubber of the gas compressor, a heat exchanger, a pressure reducing valve, and a pressure vessel. A disclosed method includes causing a stream of gas to flow from the scrubber of the gas compressor to the heat exchanger, adding heat to the gas via the heat exchanger, lowering the pressure of the gas via the pressure reducing valve, providing the gas to the pressure vessel, removing liquids from the gas via a coalescing type filter element of the pressure vessel, and providing the conditioned fuel gas from the pressure vessel to the engine of the gas compressor. The gas is taken downstream from a mist extraction device of the scrubber and the scrubber is part of a last stage of compression in the multi-stage gas compressor.

A heat exchanger includes a body defining a flow channel, and a pin extending across the flow channel, the pin including an at least partially non-cylindrical shape. The pin can be a double helix pin including two spiral branches defining a double helix shape. The two branches can include a uniform winding radius. The two branches include a non-uniform winding radius. The non-uniform winding radius can include a base radius and a midpoint radius, wherein the midpoint radius is smaller than the base radius. The two branches can be joined together by one or more cross-members.

The present invention discloses a tubular thick film heater protection apparatus, including: an upper tube, where the upper tube includes an upper tube side surface and a toroid; an outer ring surface of the toroid is integrally connected to an upper portion of the upper tube side surface, a flange downwardly extends along an inner ring surface of the toroid, and a space between the flange and an inner side wall of the upper tube side surface forms an upper groove; and a base, where the base is provided with a lower groove, the base is provided with an elastic contact piece, and a terminal contact of the elastic contact piece can be connected to an electrode through contact; and the base is provided with a wiring terminal.

A heat exchange device and a freeze dryer. The freeze dryer comprises a bearing device, and an evaporation device and a condensation device which are provided on the bearing device, at least one of the evaporation device and the condensation device comprising a structure of the heat exchange device. The heat exchange device is integrally molded by extrusion, and the heat exchange device is provided with at least one medium flow passage, a plurality of fins are formed on the outer periphery of the medium flow passage, and the fins being provided at intervals to form gaps allowing airflows to pass therethrough. The heat exchange device and the freeze dryer of the present disclosure can be designed to be smaller, reducing the volume, and facilitating miniaturization of products.

A support form defining a longitudinal axis is provided. The support form includes a first section, a second substantially solid section, and at least one flow feature form. The first section includes a plurality of unit cells of a first material joined together to form a lattice. The second section includes a second material and surrounds the first section. The at least one flow feature form is defined in the second section and is configured to generate a flow feature on a heat exchanger tube formed by plating the support form.

A reaction device is provided with a first wall that defines an interior in which a stirring mechanism is located. A heat exchanger is at least partly provided on the first outer wall surface facing away from the interior and/or on the stirring mechanism, wherein the heat exchanger has a grate structure, and at least two layers are provided which have a grate structure. Thus, it is possible to transfer heat in a precise and efficient manner primarily by means of thermal radiation in endothermic processes at different temperature levels, in particular pyrolysis, gassing, and reforming processes, and thereby use the exhaust heat for other processes.

A double-tube internal heat exchanger has an outer tube, an inner tube, and a turbulator. The inner tube is inserted into the outer tube and defines an inner flow channel therein through which a first fluid flows. The inner tube and the outer tube define an outer flow channel therebetween through which a second fluid flows. The turbulator is disposed inside the inner flow channel. The inner tube includes an inner surface defining an inner groove that helically extends on the inner tube along an axial direction of the inner tube. The turbulator includes a flexible core portion extending along the axial direction and loops protruding from the flexible core portion in a radial direction of the inner tube. Each of the inner tube and the outer tube includes a bent portion that is formed by bending both the inner tube and the outer tube together with the turbulator.
