A method for transporting a viscous fluid through a heat exchanger line that includes transporting a viscous fluid through a connecting piece with an excess pressure release component, where the excess pressure relief component separates an interior of the connecting piece from a discharge line in the connecting piece, and is fixed to an edge of the discharge line, mixing a fluid flow in a region of the excess pressure relief component using a mixing element disposed in the interior of the connecting piece and causing the excess pressure release component to release at least a portion of the fluid through the discharge line when the pressure of the fluid is equal to or greater than a preset excess pressure.

A heat sink may comprise a core body having a phase change material cavity enclosed therein; and a phase change material disposed within the phase change material cavity comprising a paraffin wax and/or a fatty acid ester.

This document describes techniques for implementing phase-change cooling in a three-dimensional structure. A three-dimensional structure having three-dimensional curvatures is fabricated to include a phase-change chamber with a fluid in a saturated thermodynamic state. As part of fabrication, specific mechanisms may be included that create a thermo-mechanical network that improves thermal performance of the phase-change chamber and also provides structural integrity to the three-dimensional structure.

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 liquid-cooled server chassis includes: a case; one or more liquid-cooling modules, each liquid-cooling module including a housing, a gas outlet valve, and a liquid return valve, wherein the gas outlet valve and the liquid return valve are opened in an operation of the liquid-cooling module, and the liquid-cooling module accommodates a single server and is filled with coolant during operation; a connector configured to connect the liquid-cooling module to a power source; and a circulation portion including an gas outlet pipe, a liquid return pipe, a vapor processing part, and a liquid collecting part. The server can be taken out separately for maintenance or replacement without affecting the operation of other servers. In addition, a condenser is disposed outside the liquid-cooling module so that the coolant cannot contaminate the server and the reliability of the chassis is improved.

A relief valve 1 includes: a housing 6 connected to a supply-side connection pipe 4a and a discharge-side connection pipe 5a and has an inflow port 61c and an outflow port 62c; a valve seat (an opening rim 61a) provided in the housing 6; a main valve body 7 which is placed in the housing 6, and capable of cutting off communication between the inflow port 61c and the outflow port 62c in the housing 6 by being seated on the valve seat (the opening rim 61a); and a biasing member 8 that biases the main valve body 7 toward the valve seat (the opening rim 61a), wherein the inflow port 61c is provided in the housing 6 such that the inflow port 61c is decentered with respect to a central axis line of the main valve body 7 in a direction in which a supply pipe 4 extends.

Heat exchange devices, including aseptic cooler devices, and systems including same are provided. Methods of using heat exchange device are also provided. In a general embodiment, the present disclosure provides heat exchangers having an open chamber configuration and including a first section containing a cooling or heating media and a second section containing a food product. The first section includes a level detecting device that is configured to maintain a level of cooling or heating media in the first section, while preventing the cooling or heating media from pressurizing the first section. The open chamber configuration provides an air break at a top portion of the first section that ensures that the cooling or heating media entering the first section is at, or close to, atmospheric pressure.

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 phase change cell includes a housing enclosing a phase change chamber that holds a phase change material and a gas pocket. The housing includes a side wall extending between first and second end walls. A capillary is disposed in an interior surface of the side wall. In response to heating of the phase change cell, the capillary is configured to draw the phase change material in a liquid phase towards the periphery of the phase change chamber. A temperature sensor is coupled to the housing in a vicinity of the capillary to measure the phase change temperature. According to another aspect, the housing includes a moveable surface that bounds a portion of the phase change chamber. The phase change temperature of the phase change material changes based on the position of the moveable wall.
