Provided is a heat-exchanging and mixing device and a solution transport and cooling unit which are capable of efficiently performing heat transfer with respect to a heat-exchange target, while stirring and mixing the heat-exchange target, to obtain an advantageous effect of being able to significantly hinder accumulation of a solid content in the solution transport and cooling unit. The heat-exchanging and mixing device comprises a heat exchanger tube and a spiral mixing member having a width approximately equal to an inner diameter of the heat exchanger tube and disposed inside the heat exchanger tube. The spiral mixing member is comprised of a strip-shaped member having an inter-slit region.

A heat exchanger includes a housing with an inlet port, an outlet port, an interior facing surface defining a coolant channel, a first opening surrounded by an exterior facing surface, and a second opening defined by a first inner diameter. A tube assembly defines a plurality of exhaust gas flow channels and a plurality of coolant cross channels within the housing. A first diffuser directs a first fluid into the tube assembly and is joined to a first header plate, which separates the first fluid from a second fluid within the coolant channel. A second diffuser directs the first fluid out of the tube assembly. The second diffuser is located within the second opening and sealed to the second opening by seals around the second diffuser.

A heat exchanger device provides refrigeration in refrigerated vehicles operated by liquefied natural gas (LNG) which must first be regasified. The great temperature difference between heat-discharging cooling chamber air and heat-absorbing LNG evaporating at up to −161° C. conducts the heat flow via an introduced intermediate medium circulating in a closed circuit to avert the risk of combustible natural gas leaking. The intermediate medium is non-combustible, environmentally-benign liquid heat exchange media having low viscosity. The liquid heat exchange media operating temperature is kept above −85° C. using an additional thermal resistance in the heat exchanger which evaporates the LNG, so that the heat flow flows with sufficient temperature drop. A thin protective dry gas layer formed using sheathing tubes enclosing a tubular heat exchanger's tubes coaxially serves as this thermal resistance. Possibly escaping natural gas is determined by monitoring pressure in the layer, and the LNG supply interrupted.

A heat exchanger includes: a heat exchanger body which includes an adhesive lower damping material which is provided on a lower outer peripheral surface of a lower tubular member exposed from a lower buffer material provided in each of both end portions in both end portions of the lower tubular member constituting at least a lower header and is formed such that at least a portion of each of both end portions extends between the lower tubular member and the lower buffer material; and a casing which includes first and second abutment portions against which the lower buffer material abuts and a condensate water discharge unit which discharges condensate water to an outside.

A plant or refinery may include equipment such as reactors, heaters, heat exchangers, regenerators, separators, or the like. Types of heat exchangers include shell and tube, plate, plate and shell, plate fin, air cooled, wetted-surface air cooled, or the like. Operating methods may impact deterioration in equipment condition, prolong equipment life, extend production operating time, or provide other benefits. Mechanical or digital sensors may be used for monitoring equipment, and sensor data may be programmatically analyzed to identify developing problems. For example, sensors may be used in conjunction with one or more system components to detect and correct maldistribution, cross-leakage, strain, pre-leakage, thermal stresses, fouling, vibration, problems in liquid lifting, conditions that can affect air-cooled exchangers, conditions that can affect a wetted-surface air-cooled heat exchanger, or the like. An operating condition or mode may be adjusted to prolong equipment life or avoid equipment failure.

An apparatus and method of forming a heat exchanger including a thermally compliant material and geometry with a core having a first set of flow passages and a second set of flow passages passing through the core.

At least one of the first and second manifolds can include an in-situ compliant portion to provide for compliance during thermal expansion of the heat exchanger.

The invention relates to an heat exchanger possibly for exchanging heat within a vehicle. The heat exchanger includes a housing with an inlet port, an outlet port, an interior facing surface defining a coolant channel, a first opening surrounded by an exterior facing surface, and a second opening defined by a first inner diameter.
