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 battery module with one or more battery cells and a heat exchange member placed in thermal communication with the battery cell, and a method of making a heat pipe system from the heat exchange member. The heat exchange member includes a container with a heat transfer fluid disposed therein. In one form, the heat transfer fluid is capable of going through a phase change as a way to absorb at least a portion of heat present in or generated by battery cell. A pressure control device cooperates with the container and heat transfer fluid such that upon attainment of a predetermined thermal event within the battery cell, the pressure control device permits liberation of at least a portion of the heat transfer fluid to an ambient environment, thereby relieving pressure on the container and removing some of the excess heat caused by the thermal event.

A system and method for the concurrent condensation of a nitrogen-rich vapor and vaporization of an oxygen-rich liquid in a distillation column based air separation unit is provided. The disclosed system includes a condenser-reboiler heat exchanger located between a lower pressure column and a higher pressure column and configured to condense a nitrogen-rich vapor from the higher pressure column and partially vaporize an oxygen-rich liquid from the lower pressure column. Within the condenser-reboiler heat exchanger, the nitrogen-rich vapor flows in an upward direction such that any non-condensables present in the nitrogen-rich vapor will accumulate proximate the upper portion or top of the condenser-reboiler modules where they can be easily removed through venting by means of a venting apparatus having a plurality of perforated tubes.

A hot water storage unit 100 having a vessel 102, in which hot water is storable, an outer casing 104 enclosing the vessel 102, a hot water outlet 114 for heated water to exit from inside the vessel 102, and a relief device 106. The relief device 106 relieves excess pressure and/or temperature from inside the vessel 102 by allowing water to escape from inside the vessel 102 and exit from the relief device 106. The relief device 106 comprises a housing 108 containing the operational components of the relief device 106. The relief device 106 is removably retainable relative to the vessel 102 such that the housing 108 of the relief device 106 is located substantially behind the outer casing 104 of the hot water storage unit 100 on the inner side 122 of the outer casing 104. The hot water storage unit 100 can be made by removably retaining the relief device 106 relative to the vessel 102 and placing the outer casing 104 around the vessel 102 so that the housing 108 of the relief device 106 is located substantially behind the outer casing 104, on the inner side 122 of the outer casing 104, after the outer casing 104 has been placed around the vessel 102.

An apparatus for preheating hydraulic oil which is located at low temperatures in at least one air-cooled hydraulic oil cooler, wherein at least one hydraulic oil cooler is arranged outside an engine compartment, in particular of a large hydraulic excavator, characterized in that the oil, in particular hot oil, coming from a tank is fed to the inlet box of the hydraulic oil cooler and is passed on via connecting lines and an interposed pressure relief valve or a non-return valve to the outlet box of at least one hydraulic oil cooler, wherein the outlet box and the cold oil located therein can be heated and fed to the tank.
摘要:
A novel water heat exchanger with a helix coil incorporated into a stainless steel elongated variable diameter cylindrical housing. A buffer tank is incorporated within the lumen of the helix coil. In one embodiment, the heat exchanger utilizes a radial direct-firing burner and a blower-driven hot flue gas to heat water for domestic and commercial use. In one embodiment, at least a rope seal is disposed between adjacent coil loops of a portion of the helix coil for enhancing heat transfer to the helix coil. In one embodiment, solar and electric heating systems are combined with the helix coil heat exchanger and disposed within the buffer tank to provide supplemental heating. In another embodiment, the heat exchanger further comprises a Stirling engine comprised of a free piston having hot and cold ends that is disposed within the cavity taken up the buffer tank, wherein the hot end receives heat from the burner and the cold end is cooled by the incoming cold water line to form an electric power generator.

The present invention provides a heat exchanger including 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.
