A coldplate assembly includes a plurality of leak-tight conduit modules provided between a base and a cover to couple a first manifold cavity to a second manifold cavity. Each leak-tight conduit module includes a heat conducting structure and is pre-constructed and pre-tested prior to integration into the coldplate assembly. Each leak-tight conduit module is sealed only near the ends of the module that are disposed in the respective manifold cavity.

When products to be shipped are temperature-sensitive, it is necessary to maintain a substantially uniform and constant temperature to avoid spoilage. As a result, thermal shields are often placed on top of the products. Many designs for thermal shields have been considered in the past but improvements are still desired. Accordingly, there is provided a multilayer thermal shield (100) comprising a thermally conductive layer (108), and at least one heat exchange fluid circuit (120) coupled to a first surface of the thermally conductive layer, the at least one heat exchange fluid circuit comprising at least one inlet (124) configured to permit the ingress of heat exchange fluid. The thermal shield further comprises an outer insulation layer (104) connected to a first surface of the thermally conductive layer (108) and comprising grooves designed to receive the heat exchange fluid circuit. The thermal shield further comprises an inner insulation layer (110) connected to a second surface of the thermally conductive layer (108).

The present invention relates to a heat exchange device (10) for a motor vehicle including a heat exchanger (12) with first and second collector plates (26; 28), first and second header boxes (30; 56) attached to the collector plates (26; 28) and a bundle (18; 20) of pipes (22) extending between the first and second collector plates (30; 56). Each of the collector plates (30; 56) forms a groove (54; 72) between the pipes (22) of the pipe bundle (18; 20) and a lateral end (50; 68) of the respective collector plate (30; 56). A perforated protective device (14) for the pipes (22) is attached to the heat exchanger (12) using attachment means (78, 80) bearing against the inside of the grooves (54, 72) in the first and second collector plates (26; 28).

A heat exchanger core consists of first and second fluid channels, each configured to direct flow of respective fluids through the heat exchanger core. Each first fluid channel includes first fluid flow assemblies having inner channels formed by inner channel walls that contain the first fluid, each inner channel surrounded by a barrier channel having a barrier channel wall that isolates the barrier channel from the second fluid. One or more barrier channel vanes support the inner channel within the barrier channel. Each barrier channel provides a void space between the inner channel wall and the barrier channel wall, thereby fluidly separating the first fluid from the second fluid. Each barrier channel can receive the first or second fluid in the event of a breach of the inner channel wall or the barrier channel wall, thereby preventing intra-fluid contamination.

A heat exchanger comprises an outer shell extending between axially opposed ends and having a first fluid inlet and a first fluid outlet, one or more tubes passing through the tubular shell, a collection vessel disposed in an upper surface of the outer shell or the first fluid outlet, and a level sensor configured to detect the presence of the second heat exchange fluid within the collection vessel. The first fluid inlet and the first fluid outlet provide a first fluid pathway for a first heat exchange fluid through the outer shell, and the one or more tubes are configured to provide a second fluid pathway for a second heat exchange fluid between a second fluid inlet and a second fluid outlet.

A nuclear reactor includes a heat exchanger that transfers thermal energy from a primary reactor coolant to a secondary coolant. The heat exchanger is a compact plate heat exchanger and more than one heat exchanger may be spaced about the reactor vessel. A plurality of heat exchangers may be spaced vertically, radially, and/or circumferentially about the reactor vessel. A first heat exchanger may be in fluid communication with a second heat exchanger. Two or more heat exchangers may share a thermal load and therefore share thermal stresses. The heat exchanger may have a third fluid flow path and a third fluid. The third fluid may be used to remove fission products, be used for leak detection, create an oxidation layer to inhibit migration of activation products, and/or provide additional heat transfer.

A geothermal heating and cooling system that uses a water source to provide a heat transfer medium is provided. Elements of the system may include a water source, one or more circulation loops coupled to the water source, a heat exchanger and/or heat pump, and/or a monitoring component configured to monitor for conditions within the system, including leak integrity and water quality.

A plate heat exchanger includes a heat exchanger plate having a heat transfer area and an edge area, extending around the heat transfer area. The heat exchanger plate is a double wall plate formed by two adjoining plates compressed to be in contact with each other. A sensor configured to sense at least one parameter and to produce a signal depending on the parameter includes a sensor probe that is provided between the adjoining plates.

A seal configured for use in a chiller refrigeration system is provided including a first flange and a second flange. The first flange and the second flange are coaxially aligned and in direct contact. The second flange includes at least one groove within which a first sealing mechanism and a second sealing mechanism are positioned. The first sealing mechanism and the second sealing mechanism are separated by a distance such that a chamber configured to receive a pressurized gas is formed between the first and second sealing mechanisms.

A flow-path forming gasket is interposed between peripheries of each adjacent ones of stacked heat transfer plates; communicating-path forming gaskets are each installed, surrounding the passage holes in each adjacent ones of the heat transfer plates alternately; and thereby a first flow path adapted to pass a high-temperature fluid, a second flow path adapted to pass a low-temperature fluid, and communicating paths adapted to cause the fluids, respectively, to flow in and out of the first and second flow paths are formed alternately on opposite sides of each heat transfer plate. A drain hole is formed in each of the heat transfer plates to discharge fluid leaking from the first flow path, the second flow path, or the communicating path. The drain hole is surrounded by gaskets isolated from the first flow path, the second flow path, or the communicating path. A leakage flow path or a leakage collector is formed by the gaskets.
