  • Patent number: 6244197
    Abstract: Chimney-like cooling passages that have opposite outlet and inlet end regions open to ambient air also have central regions that extend through heated components of industrial furnaces. The passages preferably are defined by conduits that are oriented and configured in a manner that enables thermally induced flows of ambient air to self establish through the conduits to cool the furnace components once the furnace components become heated. The passages function like chimneys, with each having its outlet located higher than its inlet so that ambient air will effectively rise as it flows from the inlet to the outlet. The passages may provide increases in cross-sectional area somewhere along their lengths so that heated ambient air expanding in the passages is encouraged to discharge from the less restrictive, larger area outlets rather than from the smaller area inlets.

The chamber is cooled both by exposing the side wall (3) to the atmosphere and by using a thermosiphon effect to cause the fluid in the intermediate space (24) to flow through a closed circuit (30) including said intermediate space and at least one pipe (31) located outside the chamber and connected thereto at two vertically spaced points. The device may be used in oil industry exchangers.

  • Patent number: 5505254
    Abstract: A tube supporting device is provided for supporting closely packed tubes in a heat exchanger. The device has a support plate transversely disposed with respect to the tubes. The support plate has a plurality of holes formed therein which are penetrated by the tubes and which support the tubes against lateral movement. The holes can be a variety of shapes to create one or more gaps between the peripheral surfaces of the holes and the outer surfaces of the tubes. The gaps enhance the flow of condensate which has formed on the tubes and causes the condensate to flow to a bottom portion of the heat exchanger without moving to and collecting on the support plate. The holes also inhibit lateral movement of the tubes.

  • Patent number: 4918934
    Abstract: In a method for cooling rooms, the energy exchange between warm room air and cold air takes place through inherent convection of the air by means of a drop shaft arranged in the room, which has cooling surfaces in its upper part, at which the in-coming warm room air cools, and flows downwards owing to the specific weight difference. The cooled air leaves the drop shaft at the lower end in a laminar flow and then spreads in the room in an unbroken cool layer. The air leaving the drop shaft can also be deflected into a hollow floor. It is possible to use a fan to add to the cooled air current moved by gravity disturbing air, which then occasions turbulence.

  • Patent number: 4703889
    Abstract: A radiator comprising a plurality of longitudinally finned tubes formed from extruded aluminum and extending between upper and lower header pipes likewise of extruded aluminum. A water-tight joint is formed at the junction of each finned tube with the adjacent header by means of an interference fit nipple. The fins are shaped so as to define a gap between adjacent finned tubes through which air to be heated may be drawn. Such air enters a chamber defined between each adjacent pair of finned tubes and exits to the rear via louvers formed in the rear fins of the finned tubes, taking the general direction of arrows A. A degree of control of the heat output of the radiator may be achieved by rotation of a flap located at the bottom of the space between the radiator and the adjacent wall surface.

  • Patent number: 4628992
    Abstract: In order to cool heat generating components on an electronic assembly without contamination by particles carried in a cooling gas stream, a cold plate is disposed adjacent the assembly, defining a gap region therebetween. The cooling gas is directed in proximity to the cold plate, dissipating heat transferred from the components to the plate. To enhance overall heat dissipation of the apparatus, an aperture is defined between the gap region and the gas stream, so that a negative pressure is induced in the gap by virtue of the Bernoulli principle. This pressure difference induces convection within the gap, increasing heat flow between the components and the plate, and resulting in overall improvement in heat dissipation. Embodiments in which the gas stream flow is parallel and transverse to the cold plate are described.

  • Patent number: 4561387
    Abstract: A liquid cooling system for a super-charged internal combustion engine in which the turbocharger is connected to the forced circulatory cooling system effective during the operation of the engine. In order to prevent an overheating of the turbocharger after the internal combustion engine is turned off, the turbocharger is equipped with a further cooling circulatory system maintained by thermo-syphoning action. A volume expansion tank present in the cooling circulatory system of the internal combustion engine is thereby used as heat exchanger for cooling off the cooling liquid, which is constructively matched for this particular application.
