A heat exchanger with a tube bundle wound in a helical manner about a longitudinal axis. The tube bundle includes at least two tube sections which are placed beside each other in the direction of the longitudinal axis. The tube sections each include a helically wound tube with has an internal cross-section which is constant over the helical winding thereof.

An apparatus for aligning tubes of a heat exchanger includes a generally planar body having an insertion end and an actuator end, a first driving member received by the body and extending between the insertion end and the actuator end, the first driving member being movable axially with respect to the body, and a first biasing member operatively connected to the first driving member. The first driving member is actuatable to move the first biasing member between a clearance position in which the first driving member lays generally flat within respect to the body, and an extended position in which the first biasing member extends generally perpendicular from the body.

A heat exchange, which includes a casing having a cylinder; two connectors respectively attached to one end of the cylinder through the small opening; two convex heads respectively connected through the opening end to the large opening of a connector; a core disposed inside the casing; and two heat transfer medium passages. In this way, the space at the ends of the casing of the heat exchanger may be enlarged, thereby providing a space large enough to accommodate the construction personal and better working environment for two-side welding and future maintenance and wider selection range of material of the casing of the heat exchanger; a buffer area is provided for the flow of the heat transfer medium, and the auxiliary like baffles may be mounted inside the convex heads as required to further improve the heat exchange efficiency and reduce the cost.

An energy recovery ventilator cabinet containing a plurality of enthalpy wheels. The enthalpy wheels are substantially perpendicular to a stream of forced air, allowing the air to pass through the wheels. The enthalpy wheels are also disposed such that portions overlap, allowing multiple enthalpy wheels to be disposed in a smaller space than if the enthalpy wheels were placed side by side. This arrangement has led to energy recovery effectiveness similar to that obtained by a larger, single enthalpy wheel, but has the advantage of using less space.

An application system for applying a coating agent onto a component, in particular for applying a sealant onto a motor vehicle body part, includes a material supply for providing the coating agent, a temperature control device for controlling the temperature of the coating agent, an applicator for applying the coating agent, and a coating agent line between the material supply and the applicator. The temperature control device controls the temperature of the coating agent in the coating agent line downstream of the material supply.

A method of constructing a plate fin heat exchanger includes joining a first side bar formed from a nickel-iron alloy to a first end of a fin element formed from a nickel-iron alloy through a first nickel-iron alloy bond, and joining a second side bar formed from a nickel-iron alloy to a second end of the fin element through a second nickel-iron alloy bond to create a first layer of the plate fin heat exchanger. The fin element defines a fluid passage.

A heat exchanger for an ice-making machine comprises a generally cylindrical, tubular body defining a generally cylindrical, internal heat exchange surface, and at least one refrigerant circuit comprising at least one refrigerant passage disposed about the outer surface of the tubular body, at least a portion of the refrigerant circuit being brazed to the outer surface of the tubular body.

To provide a method for producing a solid fuel that can efficiently evaporate moisture contained in a slurry by enhancing heat exchange efficiency.

The method for producing a solid fuel of the present invention includes the steps of: preparing a slurry by mixing powdery low-grade coal and oil; evaporating moisture contained in the slurry by heating; and separating the slurry obtained after the evaporation step into solid and liquid, wherein the evaporation step includes the steps of: preheating the slurry in a first circulation route; and heating the preheated slurry in a second circulation route that is different from the first circulation route. Preferably, in the preheating step and the heating step, a multitubular heat exchanger is used, the heating medium is supplied to the shell side, and the slurry is supplied to the tube side. Preferably, the process steam generated in the evaporation step is used as the heating medium for anyone of the preheating step and the heating step, and externally introduced steam is used as the heat medium for the other.

The invention relates to a heat exchange device characterized by a particular configuration of the liquid inlet or outlet manifold in which it incorporates a baffle formed from the shell itself. This configuration allows not only suitably orient the inflow into regions of the tube bundle of the exchanger where convection must be more intense, but also allows generating a flow suitable for reaching all the regions having a higher convective heat transfer requirement. Configuring a baffle from the shell prevents incorporating and manufacturing specific additional parts, as well as the additional operations required for their configuration and attachment to the heat exchanger.

An autoclave system comprises an autoclave vessel 210, for performing a leaching operation on sacrificial ceramic cores (not shown) and a storage vessel 220 for containing caustic leaching fluid 230. Interposed in a fluid flow path between the vessel 210 and the tank 220 is a heat exchange unit 240, comprising a body 250 containing a thermal exchange medium, in the form of water 260, and first and second thermal exchange conduits represented at 270 and 280. A thermal exchange medium inlet pipe 290a and a thermal exchange medium outlet pipe 290b are provided to the body so that the medium 260 can be replenished, preferably substantially continuously, to optimize thermal transfer efficiency.
