摘要:
There are provided an apparatus for heat exchange by using a braided fabric woven from a thermally conductive wire material and a light emitting diode (LED) lighting device. The apparatus comprises a braided fabric (1) woven from a thermally conductive wire material, and a heat dissipating or absorbing object (2) is fixed with the braided fabric (1) by using methods such as welding, adhering with a thermally conductive adhesive and casting, so as to ensure that heat energy is effectively conducted between the heat dissipating or absorbing object (2) and the thermally conductive wire of the braided fabric (1), and heat is dissipated to air or absorbed from air by means of a heat dissipating surface of the thermally conductive wire of the braided fabric (1). The apparatus is changed from a large and heavy metal member into the braided fabric (1) woven from a small amount of metal wires, thereby considerably reducing a weight and a volume, and fundamentally solving a heat dissipation problem which has hindered rapid development of a LED.

It is an object of the present invention to obtain a compact and high performance heat exchanger low in its pressure loss of fluid and a refrigerating air conditioner. The heat exchanger of the present invention is a heat exchanger 10 including a first flat tube 1 in which a low temperature fluid flows and a second flat tube 2 in which a high temperature fluid flows that is laminated on the first flat tube and arranged so that the flowing direction of the high temperature fluid is parallel to the flowing direction of the low temperature fluid. At least one of the flat tubes is formed with a plurality of flat tubes arranged in the direction of lamination. Both ends of the plurality of the flat tubes are bent in the direction intersecting at right angles to both the flowing directions of the fluids respectively and the direction of lamination. Parallel passages are formed by the plurality of the flat tubes and an inlet header and an outlet header. Either of the inlet header or the outlet header is formed with a tubular header. The plurality of the flat tubes forming the parallel passages are bundled and connected to the tubular header so that the axial direction of the tubular header is the same as the flowing direction of the fluid in the flat tube.

Method for processing a fluid, the method comprising sparging a fluid within the compartment of a container with an initial gas so that the initial gas passes through a portion of the fluid to form a humid gas, passing the humid gas out of the compartment of the container and into a condenser bag, cooling the humid gas within the condenser bag so as to separate the humid gas within the condenser bag into a condensed fluid and a dehumidified gas, and returning the condensed fluid back to the compartment of the container or collecting the condensed fluid at a separate location.
摘要:
The present invention is a cross-flow evaporator adapted to generate vapor from the heat of the exhaust gases from an internal combustion engine. The evaporator is constituted, among other elements, by two plates (1, 2) spaced from one another which contain chambers (1.1, 2.1). The heat exchange tubes (3) alternately communicate the chambers (1.1, 2.1) of both plates (1, 2) , establishing a specific path for the fluid intended to change phase. The tubes (3) extending between the chambers (1.1, 2.1) of the two plates (1, 2) are arranged transverse to the flow of the hot gas. This evaporator is suitable for heat recovery systems using a Rankine cycle, making use of the heat from the exhaust gases. The invention is characterized by a special configuration of the walls (2) which prevents the crack failure or damage caused as a result of the differential expansion between the exchange tubes (3) and said walls (2).
