A heat exchanger assembly including an elongated tubular heat exchanger enclosure defining an interior chamber. A tube sheet is positioned within the interior chamber of the heat exchanger enclosure separating the interior chamber into a shell side and a channel side. The interior portion is configured to removably receive a tube bundle positioned within the shell side of the interior chamber. An annular sleeve member is positioned within the channel side of the interior chamber of the heat exchanger enclosure. An annular elastic torsion member is positioned within the channel side of the interior chamber of the heat exchanger such that the sleeve member is positioned between the tube sheet and the elastic torsion member. The elastic torsion member has an inner circumference deflectable relative to its outer circumference for torsioning the elastic torsion member.

One method disclosed herein of processing a process fluid that comprises dissolved gas includes performing a degassing process on the process fluid by heating the process fluid via heat transfer with a heat transfer fluid, wherein at least some amount of the heat transfer fluid condenses in the first heat transfer process and latent heat of the heat transfer fluid as it condenses is used to increase the temperature of the process fluid. Thereafter, the heat transfer fluid is passed through an expansion device so as to produce a post-expansion heat transfer fluid. The temperature of the heated process fluid is decreased by performing a second heat transfer process between the post-expansion heat transfer fluid and the heated process fluid, wherein the temperature of the post-expansion heat transfer fluid is increased and the latent heat that was supplied to the process fluid in the first heat transfer process is removed.

A cabin condenser for a heating, ventilation, and air conditioning (HVAC) system for a battery electric vehicle (BEV). The cabin condenser includes a first cabin condenser portion and a second cabin condenser portion. A regulator is configured to control flow of refrigerant from the first cabin condenser portion to the second cabin condenser portion.

Provided is a heat exchanger, including: a refrigerant distributor including: a gas-liquid separating portion having a function of separating a gas-liquid refrigerant mixture into a liquid refrigerant and a gas refrigerant; and a distributing portion provided to the gas-liquid separating portion. A plurality of heat transfer pipes connected to the distributing portion. The plurality of heat transfer pipes are arranged side by side in a first direction, and extend along a second direction intersecting with the first direction. When the refrigerant distributor is viewed along a direction orthogonal to each of the first direction and the second direction, a first space forming portion overlaps a region of the plurality of heat transfer pipes. When the refrigerant distributor and the heat transfer pipes are viewed along the first direction, a clearance is present between the gas-liquid separating portion and the heat transfer pipes.

Provided is a refrigerant distributor including: a first space forming portion having a first refrigerant port and a second refrigerant port; and a second space forming portion, which extends laterally from a lower part of the first space forming portion, and has a plurality of heat transfer pipe connecting portions. A gas-liquid refrigerant mixture flows into the first space forming portion through the first refrigerant port. Heat transfer pipes are connected at positions of the plurality of heat transfer pipe connecting portions in the second space forming portion.

A heat exchanger unit for a fluid circuit of a motor vehicle includes a plurality of fluid connections for a through-flow of a working fluid, a fluid distributor fluidically connected to the fluid connections, and a fluid connector fluidically connected to the fluid connections. The fluid distributor is structured and arranged to distribute the working fluid among the fluid connections, and the fluid collector is structured and arranged to collect the working fluid after flowing through the fluid connection. At least a portion of the fluid distributor and/or the fluid collector includes a surge tank for the working fluid.

A heat exchanger for a vehicle is disposed in a fluid circuit in which a fluid is circulated according to an operating condition of the vehicle. The heat exchanger includes a tank and a pressure adjuster. The tank defines a tank chamber therein and is configured to allow the fluid to flow through the tank chamber. The pressure adjuster is disposed inside the tank and defines a damper chamber separately from the tank chamber. The pressure adjuster is configured to be displaceable or deformable to expand and reduce the damper chamber. The damper chamber is filled with a compressible gas. The pressure adjuster is configured to reduce the damper chamber in response to an increase in a pressure of the fluid in the tank chamber. The pressure adjuster is configured to expand the damper chamber in response to a decrease in a pressure of the fluid in the tank chamber.

This disclosure pertains to a device for removing air from a coolant liquid of a coolant system. The device has a body with a swirl pot at one end and a manifold extending from the swirl pot to an opposed end of the body. The swirl pot has a fluid inlet for receiving coolant fluid of a first air concentration and a fluid outlet for discharging coolant fluid of a second concentration less than the first. The manifold has a first fluid pipe connected to a plurality of outlet pipes that extend transversely to the first fluid pipe and are spaced there along.
