Abstract:
Freistehender Massivabsorber in der Form einer entfernt von einem Gebäude aufgestellten Säule (2), die aus einem tragenden Betonkörper (39, 58) besteht, in dem die Rohre (68) eines Wärmetauschers (38) eingebettet sind, wobei der Massivabsorber aus mehreren zueinander konzentrischen Schalen (32, 33, 34, 39) besteht, von denen eine der Schalen als tragender Betonkörper (39, 58) ausgebildet ist und wobei die erste, äußerste Schale aus einer mehrere Seiten des Massivabsorbers (2) umfassenden, das Sonnenlicht erfassenden Glasscheibe (32) besteht, die einen mehrere Seiten des Massivabsorbers (2) umfassenden Luftspalt (33) als zweite Schale begrenzt, welcher Luftspalt als dritte Schale einen primären Wärmetauscher (36) begrenzt, der in einem ersten Pufferspeicher (35) eingebettet ist.
Abstract:
There is provided a heat exchange member which does not easily suffer from breakage due to thermal stress by relaxing the thermal stress. The heat exchange member is provided with a honeycomb structure (1) and a covering member. The outer peripheral wall (7) of the honeycomb structure (1) has at least one slit (15). The covering member covers the honeycomb structure (1) so that the heat exchange can be carried out between a first fluid and a second fluid. The heat exchange member (10) performs heat exchange by means of the outer peripheral wall (7) of the honeycomb structure (1) and the covering member in the state where the first fluid passing through the cells (3) and the second fluid passing through the outside of the covering member are not mixed with each other.
Abstract:
An apparatus for exchanging heat with a fluid includes a heat exchanger having first and second opposing surfaces and a plurality of flow passages permitting axial fluid flow between the surfaces. A manifold having an interface surface is in thermal contact with the first surface and includes a thermally conductive body for conducting heat in an axial direction between the interface surface and a heat transmitting surface. A plurality of feed passages extend through the thermally conductive body in a transverse direction, the passages having an inlet for receiving or discharging fluid. A plurality of distribution passages have ends in fluid communication with at least one of the feed passages and openings distributed over the interface surface. The distribution passages are configured to cause a change in fluid flow direction between a transversely directed flow in the feed passages and an axially directed flow at the openings.
Abstract:
A flow path member includes silicon nitride ceramics, the flow path member being provided with an inlet port; an outlet port; and a flow path connected to the inlet port and the outlet port inside the flow path member, wherein a plurality of needle-shaped crystals which exist on a surface of the flow path, intersect each other.
Abstract:
Three-dimensional porous structures comprising multiple moulded layer modules with interconnected channels in all 3D, in particular substantially axial and/or radial directions. The three-dimensional porous moulded-multilayer product (2) comprises an assembly of a plurality of moulded layer modules (1) which in turn comprise a plurality of through-holes between the layer surfaces of said moulded layer module (1); and a plurality of longitudinal recesses on at least one of the layer surfaces of said moulded layer module (1), along at least two different directions, such that when assembled with the layer surface of another moulded layer module (1) longitudinal channels are formed; wherein said through-holes and recess channels are interconnected. The production method comprises assembling of the moulded layer modules (1) by sintering, welding, ultrasonic welding, or applying rigid junctions, screws, spikes, rivets, snap fits, or combinations thereof.
Abstract:
There is provided a heat conduction member inhibiting stress generation due to a thermal expansion difference while maintaining a thermally bonded state in a case of covering a cylindrical ceramic body with a metal pipe. A heat conduction member 10 includes: a cylindrical ceramic body 11, a metal pipe 12 on the outer periphery side of the cylindrical ceramic body 11, and an intermediate member 13 held between the cylindrical ceramic body 11 and the metal pipe 12. The cylindrical ceramic body 11 has passages passing through from one end face to the other end face and allowing the first fluid to flow therethrough. The intermediate member 13 is made of material having at least a part having a Young' s modulus of 150 Gpa or less. The first fluid is allowed to flow through the inside of the cylindrical ceramic body 11 while the second fluid having lower temperature than that of the first fluid is allowed to flow on the outer peripheral face 12h side of the metal pipe 12 to perform heat exchange between the first fluid and the second fluid.
