The invention relates to a flat tube heat exchanger, in particular to a high-temperature flat tube heat exchanger for gaseous media, comprising a closed housing (5) having a tube bundle space (50) and a tube bundle, arranged in the tube bundle space (50) of the housing (5), comprising multiple flat tubes (2), there being arranged, in the flat tubes (2) and in the tube bundle space (50) between the flat tubes (2), corrugated strips (3, 6) having peaks (30, 60) and troughs (31, 61) extending in the longitudinal direction of the flat tubes (2), wherein the peaks (30, 60) and troughs (31, 61) respectively bear internally and externally against flat sides (200) of the flat tubes (2), and wherein there is provided a device for externally applying a surface pressure to the housing (5), at least in the region of the tube bundle space (50), this pressure being higher than a pressure (p1, p2) of the media guided in the flat tubes (2) or around the flat tubes (2).

A metal-resin complex, comprising a space surrounded by a metal component and a resin component, the resin component comprising at least one fragile portion.

A pipe is provided for transporting a viscous fluid, including a pressure relief valve provided with a sealing element which separates the inside of the pipe from a discharge line and is designed to release the discharge line in the event of predetermined excess pressure. A surface of the sealing element, facing a Miler chamber of the pipe, is associated with the pipe in such a manner that the surface is flown around by a flow of the viscous fluid circulating through the pipe when in operation, and the sealing element is fixed in the closed position by a rod, the rod being displaced by the predetermined excess pressure such that the thus connected sealing element releases the discharge pipe.

A heat exchanger includes a stack of plates which form ducts. Each of the plates can have at least two openings which, in the plate stack, form at least one collecting duct and one distributor duct which connect the ducts in terms of flow. A base plate can be arranged on the plate stack and can have a seal for sealing off the heat exchanger and a flow deflector for manipulating flow through the heat exchanger. The seal and the flow deflector can form a common component.

A heat exchanger (1) contains: a bundle of at least two heat exchanger tubes (3), a heat exchanger housing (5) surrounding the bundle of heat exchanger tubes (3), wherein a liquid heat-transfer medium (7) is passed around the bundle of heat exchanger tubes (3) in the heat exchanger housing (5), a heat exchanger cap (9) sealing the top of the heat exchanger housing (5), a heat exchanger bottom (11) sealing the bottom of the heat exchanger housing (5), a feed point (13) for the heat-transfer medium (7), an outlet (15) for the heat-transfer medium (7), an emergency relief port (17) disposed in proximity to the heat exchanger cap (9). The heat exchanger (1) contains a safety device (19) disposed in proximity to the heat exchanger bottom (11).

A radiator assembly for a machine is provided. The radiator assembly includes an inlet tank adapted to receive a coolant. The radiator assembly includes a fluid line having a first end fluidly coupled to the inlet tank. The fluid line is adapted to allow passage of the coolant therethrough. The radiator assembly also includes an outlet tank fluidly coupled to a second end of the fluid line. The outlet tank is adapted to receive the coolant from the fluid line. The radiator assembly further includes a pressure compensating device fluidly coupled to at least one of the inlet tank and the outlet tank.

There are herein described energy storage systems. More particularly there are provided thermal energy storage systems comprising battery assemblies containing phase change materials and a monitoring system therefor. In addition there are provided thermal stores comprising battery assemblies having integral control means for management of the thermal energy provided by the battery assembly.

A cooling apparatus includes: an evaporator in which a coolant is housed and that evaporates the coolant; a condenser that condenses the coolant evaporated by the evaporator; a pathway section that includes a vapor path and a liquid path each placing the inside of the evaporator and the inside of the condenser in communication with each other, and that circulates the coolant between the evaporator and the condenser; a valve that is provided to at least one path out of the vapor path or the liquid path; and a pressure regulation section that increases an opening amount of the valve according to an increase in pressure inside the evaporator.

A smelting vessel includes a plurality of heat pipes (21) positioned in a refractory lining of at least a part of the hearth (9) for cooling at least a part of the refractory lining. At least one of the heat pipes includes (a) a liquid phase of a heat transfer fluid, typically water, in a lower section of the heat pipe and (b) a vapor phase of the heat transfer fluid, typically steam, in an upper section of the heat pipe. The heat pipe also includes a vent to allow vapour phase to escape from the heat pipe to reduce the pressure or the temperature within the heat pipe when the vapour pressure or the temperature in the heat pipe exceeds a predetermined threshold pressure or temperature.

A method of managing transient thermal stresses in a wall of a fluid-carrying or fluid-containing structure, the structure having a temperature ramp rate limit associated with its structure walls. The structure is provided with flow passages in the structure walls, and the temperature of the structure walls is monitored. If a rate of change of temperature of the structure walls becomes too high, fluid is circulated through the flow passages to heat or cool the structure wall during hot or cold transient thermal events, respectively.
