Implementations described herein generally relate to substrate processing equipment and more particularly to methods and compositions for temperature control of substrate processing equipment. In one implementation, a method of cooling a processing chamber component is provided. The method comprises introducing an inert purge gas into a supply reservoir containing a coolant and flowing the treated coolant to a processing chamber component to cool the processing chamber component. The coolant initially comprises deionized water and a water-soluble base.

A heat exchanger includes a first side of a heat exchanger layer with a first flow path, wherein the first flow path flows through a heat soak region and a flow region, and a second side of the heat exchanger layer with a second flow path in thermal communication with the first flow path, wherein an inlet of the first flow path and an inlet of the second flow path are proximate in the heat soak region.

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.

The present invention relates to a heat exchange device (10) for a motor vehicle including a heat exchanger (12) with first and second collector plates (26; 28), first and second header boxes (30; 56) attached to the collector plates (26; 28) and a bundle (18; 20) of pipes (22) extending between the first and second collector plates (30; 56). Each of the collector plates (30; 56) forms a groove (54; 72) between the pipes (22) of the pipe bundle (18; 20) and a lateral end (50; 68) of the respective collector plate (30; 56). A perforated protective device (14) for the pipes (22) is attached to the heat exchanger (12) using attachment means (78, 80) bearing against the inside of the grooves (54, 72) in the first and second collector plates (26; 28).

The system and method for installing external corrosion guards of the present disclosure comprises a method of protecting tubing in tubular heat exchangers from external corrosion that includes the installation of protective collars or guards around the tube outer diameter at the tubsheet plate, anti-vibration baffle, and/or pass partition plate levels. The external corrosion guards can be installed using a ridge method, where a ridge sits on a plate level, using a mechanical expansion method, and using a mechanical rolling method.

The present disclosure provides natural gas and petrochemical processing systems, including oxidative coupling of methane reactor systems that may integrate process inputs and outputs to cooperatively utilize different inputs and outputs in the production of higher hydrocarbons from natural gas and other hydrocarbon feedstocks. The present disclosure also provides apparatuses and methods for heat exchange, such as an apparatus that can perform boiling and steam super-heating in separate chambers in order to reach a target outlet temperature that is relatively constant as the apparatus becomes fouled. A system of the present disclosure may include an oxidative coupling of methane (OCM) subsystem that generates a product stream comprising compounds with two or more carbon atoms, and a dual compartment heat exchanger downstream of, and fluidically coupled to, the OCM subsystem.

An exhaust gas heat exchanger, in particular for use in a motor vehicle, having at least one first flow channel that conducts a first fluid, which first flow channel is accommodated in respective tube sheets at end areas of the first flow channel. A housing surrounds the first flow channel and forms a second flow channel for a second fluid that flows through the housing and flows around the first flow channel. Pipe sheets are inserted into the housing such that the first flow channel is sealed off from the second flow channel. A first diffuser conducts the first fluid into the first flow channel and a second diffuser conducts the first fluid out of the first flow channel. A first shielding element has a first passage and a first spacing element is placed onto a tube sheet from the side facing away from the first flow channel.
