Abstract: A shell and tube type heater exchanger is disclosed for withstanding cyclic changes in temperatures of fluid without suffering failure by removing metal from the outer periphery of a tube sheet. The central portion of the tube sheet is a smooth arching contour mating with portions of the adjoining shell proximate to the tube sheet periphery without abrupt changes of section so that the surfaces blend with one another.

Abstract: A Moisture Separator Reheater (MSR) has a plurality of tube bundles which receive high-pressure saturated (tubeside) steam therein. Steam to be reheated (shellside steam) is passed in heat-exchange relationship with the tubes of the first and second reheater tube bundles after first being dried by the panels of a moisture separator. It emerges from the shell of the reheater dried and heated. In the reheater tube bundles saturated steam at temperatures and pressures substantially higher than the shellside steam transfers heat to the shellside steam by condensation within the tubes. The steam in the second stage tube bundle is at a temperature and pressure that is substantially higher than that of the steam in the first stage tube bundle and is heating shellside steam at a higher temperature than the shellside inlet steam to the first stage tube bundle. A greater quantity of tubeside steam than is theoretically necessary is passed through the tube bundles.

Abstract: In a heat exchanger, ends of adjacent heat-conducting pipes are flattened to form joining faces and these faces are butt-welded together to form a parallel pipe heat exchanger without end plates.

Abstract: A heat transfer conduit for attachment to the end of a heat transfer vessel is arranged as a spiral and has a uniform distance between adjacent coils. The conduit has a uniform cross-section with an arcuate periphery of between 130.degree. and 150.degree. of a circle.

Abstract: A tube spacer is provided for use in a tube bundle including a plurality of spaced apart rows of tube sections. The spacer comprises an elongated member having a contour defining a helix, is adapted to extend through the spaces defined between adjacent tube sections of the rows of tube sections and to contact the outside surfaces of the tube sections, and is adapted to be removed from the tube bundle in the direction in which it extends into the tube bundle.

Abstract: In batteries of tubes conducting a heating fluid air is led through the spaces between the tubes, to be heated for use in grain drying installations or the like. Airborne dust and impurities form deposits on the tubes and impair heat transmission. The deposits are removed from the tubes by increasing at intervals the air velocity by means of a grid structure defining passages having a reduced flow area and placed in front of the interspaces between the tubes.

Abstract: The heat exchanger core comprises a fluid passage member, within which a fluid flows and outside of which another fluid flows and fin members formed on the fluid passage member for promoting heat exchange between the two fluids. The fluid passage member and the fin members are made of different kinds of aluminum alloys. The fin members serve as sacrificial anodes as well for protecting the heat exchanger core from corrosion.

Abstract: Dissipation of heat from miniature solid-state devices and the like is achieved by a resilient heat-sink structure which opens to receive a substantially flat tab or other heat-transfer body freely between two relatively-movable oppositely-disposed broad-area portions of the structure and which then closes and yieldingly holds the two portions about the body as shaped end connectors and sprung and locked as the result of simple manipulations.

Abstract: An impingement type heat exchanger in which jets of fluid are directed against opposite sides of a corrugated transfer plate that is generally perpendicular to the direction of fluid flow through the jets.

Abstract: A base housing section, a plurality of intermediate housing sections, and a head housing section are stacked one above the other in a gas-tight but readily removable manner, to form a hollow housing. The base housing section and head housing section are equipped with gas connections so that a gas from a coke plant may be circulated through the hollow housing. Each intermediate housing section has extending transversely across the interior thereof at least one group of a plurality of heat exchange tubes. Cooling fluid connection means are connected to the uppermost and lowermost groups of tubes for the passage therethrough of a cooling fluid. Adjacent ends of adjacent groups of the tubes are connected such that the heat exchange fluid passes through all of the tubes of the intermediate housing sections in a substantially sinusoidal manner.

Abstract: There is disclosed a solar water glass lined tank in which a copper tubing heat exchanger coil is installed and connected across inlet and outlet fittings of the tank. The circuit for circulation of a fluid which is to be heated or cooled is connected to these fittings for thermal exchange with fluid in the tank. Legs are secured to the tubing coil by flexible fasteners, such as plastic or plastic coated wire ties, and the tubing coil is installed in the tank prior to welding a head wall in place. The legs are spaced about the coil formation and extend from a sidewall, top-head corner junction of the tank. The legs are preferably of the same metal material as the coil and are cushioned at their ends with rubber or plastic bumpers. The head wall is welded in place and the tank is assembled for shipment and use.

The plates are arranged to define fluid passages for both water and refrigerant with the refrigerant passages having separators positioned therein. The housing is provided with partitions that cooperate with certain of said plates to define water passages which extend in a serpentine manner from the inlet to the outlet, with the inlet communicating with the greater number of water passages that gradually diminish in number from the inlet to the outlet.

Abstract: A cooler for chilling a working fluid used in a manufacturing or production process comprised of a tank having a reservoir in the bottom and one or more cooling coils mounted above the reservoir. A metering plate is inserted in the tank above the cooling coils to distribute the working fluid to be cooled over the refrigerant-containing coil at a predetermined rate. The metering plate has a plurality of tapered metering holes in a circular pattern aligned with each coil of the cooling coils mounted in the tank. The metering holes evenly distribute the hot working fluid over the cooling coils. Distribution and overflow barriers are provided on the metering plate to provide a constant maximum flow of hot working fluid through the cooling tank. Refrigerant is pumped through the cooling coils from the bottom to the top in a counterflow action with respect to the hot working fluid to be cooled.

Abstract: A serpentine or parallely formed conduit is fixed within a support and is further joined on its exterior surfaces by a plurality of fins. The fins have a plurality of louvered cups which define openings in the fins so that air or other heat transfer medium will pass through the fins and be turbulated around the conduits for improved heat transfer. Within the conduits are strips having similar louvered cups and openings therein and these also enhance turbulance of the fluid passing through the conduits to augment heat transfer.

Abstract: Disclosed is a construction of a fan shroud for a fan assembly in an internal combustion engine. The fan shroud operates to direct a flow of air generated by the rotation of the fan so that the flow is effectively passed through the radiator core. The fan shroud has an upper portion which is located above the level of the radiator core. The upper portion has, at the end facing the engine body a cut out portion which operates to decrease the amount of air flow passed through the shroud at a position located above the level of the radiator core. It is thus possible to obtain a fan apparatus of low operational noise, which can operate to generate a sufficient amount of flow of air passed through the radiator core for cooling the engine.
