Planar element adapted to form, when stacked with a plurality of other such elements, a heat exchanger, comprising an inlet region, a first zone adapted to direct flow from the inlet region towards a second zone, a second zone comprising at least one cutout in the plane of the planar element, adapted to accommodate a cooling core, a third zone, adapted to direct flow from the second zone towards an outlet region and an outlet region, the planar element comprising a first blockage protrusion disposed along a first group of said side edges, the first group comprising at least a side edge adjacent to said outlet region, and a second blockage protrusion disposed along a second group of said side edges, the second group comprising at least a side edge adjacent to said inlet region.

A valve control assembly includes a valve body having an inlet adapted to be coupled to a source of process fluid having a first temperature, an outlet, and a fluid flow path extending between the inlet and the outlet, and a bonnet coupled to the valve body. An inlet port, an outlet port, an annular plenum, an inlet passage, and an outlet passage are integrally formed in the valve body or the bonnet. The inlet port is adapted to be coupled to source of media and the annular plenum is disposed between the inlet port and the outlet port, immediately adjacent a portion of the fluid flow path. The inlet passage directs the media from the inlet port to the annular plenum, which changes a temperature of the process fluid flowing through the fluid flow path from the first temperature to a second temperature different from the first temperature.

Heat tracing systems and related methods are disclosed. An example valve includes a valve body defining a fluid flow passageway between a primary inlet and a primary outlet. The body valve has a first face adjacent the main inlet, the first face including a first groove. A first cover is positioned over the first groove to define a first heat tracing path. A secondary inlet is formed in the valve body and fluidly coupled to the first heat tracing path. A secondary outlet formed in the valve body and fluidly coupled to the first heat tracing path.

Disclosed herein is a fracturing unit for hydraulic fracturing having an engine and a fracturing pump connected to the engine through a variable speed torque converter. Also disclosed is a hydraulic fracturing system using multiple fracturing units which are sized similar to ISO containers. A hydraulic fracturing system may also force flow back water, produced water, or fresh water through a heat exchanger so that heat from the fracturing engines can be transferred to these liquids in order to vaporize them. A force cooled fractioning unit then can accept the vapor/steam in order to condense the various components and produce distilled water for re-use in the fracturing process or for release into the environment.

An in-line shutoff valve includes a valve body with an inlet chamber, an outlet chamber, and a poppet seat disposed between the inlet and outlet chambers. A poppet is movably disposed within the valve body and has an open and closed position. The poppet seats against the poppet seat in the closed position, fluidly separating the inlet chamber from the outlet chamber. The poppet is unseated from the poppet seat in the open position, fluidly coupling the inlet and outlet chambers. A manifold with a servo port and a vent port is disposed within the valve body between the inlet and outlet chambers, the vent port being in fluid communication with the servo port to cool valve internal structures when the poppet is in the closed position.

A valve control assembly includes a valve body having an inlet adapted to be coupled to a source of process fluid having a first temperature, an outlet, and a fluid flow path extending between the inlet and the outlet, and a bonnet coupled to the valve body. An inlet port, an outlet port, an annular plenum, an inlet passage, and an outlet passage are integrally formed in the valve body or the bonnet. The inlet port is adapted to be coupled to source of media and the annular plenum is disposed between the inlet port and the outlet port, immediately adjacent a portion of the fluid flow path. The inlet passage directs the media from the inlet port to the annular plenum, which changes a temperature of the process fluid flowing through the fluid flow path from the first temperature to a second temperature different from the first temperature.

A cooled isolation valve includes a valve body, a stationary element coupled to the valve body, and a movable closure element movable with respect to the stationary element between a closed position in which the movable closure element and the stationary element are brought together and an open position. One of the movable closure element and the stationary element includes a sealing element. In the closed position of the movable closure element, the sealing element provides a seal between the movable closure element and the stationary element. A fluid channel is formed in contact with the movable closure element and movable with the movable closure element with respect to the stationary element, such that a fluid in the fluid channel effects heat transfer in the movable closure element. A bellows of the isolation valve can include a metallic substrate with a ceramic coating.

An apparatus for providing liquid additive includes a tank for the liquid additive which has at least one heat distribution structure for distributing heat in a first tank section. A delivery unit is inserted into the tank for removing the liquid additive from the tank. The delivery unit includes at least one heating device. The heating device of the delivery unit and the heat distribution structure of the tank are connected to each other by at least one thermal coupling. A method for assembling the apparatus and a motor vehicle having the apparatus are also provided.

Apparatus for providing heated cleaning fluid to a vehicle surface includes an inlet port for receiving an amount of fluid, a housing bounding a reservoir in fluid communication with the inlet port, and an outlet port in fluid communication with the reservoir for dispensing an amount of heated fluid. A heater element heats fluid passing from the inlet port to the outlet port through the reservoir. A heat exchanger in thermal contact with the heater element for conveying heat to fluid within the reservoir has a strut that divides fluid entering the housing through the inlet port into two flow paths and elongated fins extending outwardly from the strut at transverse angles that bound fluid flow channels for fluid moving through the reservoir. A control circuit energizes the heater element to heat the heating element and the fluid passing from the inlet port to the outlet port through the reservoir.
