A system for condensing steam from an autoclave sterilizer includes a cooling tank and a condensing coil extending into the cooling tank. Cooling water from a source of water flows into the tank to cool the condensing coil when the temperature of the coolant in the cooling tank exceeds a predetermined value. A waste water drain is in fluid communication with the cooling tank. An air gap is located between the tank and the source of cooling water. The air gap includes an opening to atmospheric air and is configured to avoid back flow from a waste water drain toward the water source. A check valve may be used with or in lieu of an air gap to prevent back flow toward the water source.

In a seal structure for a heat exchanger, the seal structure being mounted on a baffle plate disposed in a shell included in the heat exchanger and being partially in contact with a wall surface on an inner surface side of the shell, the seal plate is composed of a plurality of thin plates which are laminated; the thin plates are in contact with the wall surface while being curved by an elastic deformation; a contact thin plate serving as one of the thin plates located on an outermost side of the curve is in contact with the wall surface; and an outer surface of the contact thin plate serving as a surface on an outside of the curve among surfaces arranged in a thickness direction of the contact thin plate is in contact with the wall surface so as to restrain seal performance from deteriorating.

An HVAC assembly may include a base portion that includes a rib outwardly extending therefrom. The base portion and the rib may be formed of a first material having a first elongation to yield. The blower housing may also include a collapsible portion that is formed of a second material and fixed to the rib by a bond between the first and second materials. The second material may have an elongation to yield that is greater than the first elongation to yield of the first material and may be configured to collapse when a force is applied to the collapsible portion.

A tray, a tray assembly, a battery pack assembly and a vehicle are provided. The tray includes a bottom plate having a plurality of sub-bottom plates and a flow channel in at least one of the plurality of sub-bottom plates. The at least one of the plurality of sub-bottom plates is configured to support a battery assembly. The tray further includes a frame disposed around and configured to support the bottom plate. The tray provides a reduced volume requirement on the cavity for holding the battery assembly. The flow channels are arranged more concisely, and a water cooling mode and an air cooling mode are employed in the tray.

A heat exchanger for transferring heat between two fluids with different temperature includes a first heat exchange element having at least one core extending longitudinally through the heat exchange element. The at least one core defines a core cavity that is configured with an inlet port and an outlet port to receive a first fluid flowing therethrough. The heat exchange element includes ribs extending continuously substantially in parallel with the at least one core along the whole length of the core. The ribs extend radially outwardly from the core and are exposed to contact with a second fluid that flows along said ribs. Each rib is divided into at least two radially extending fins at a radial distance from the core. Each fin extends to a proximity of an outer casing surrounding the first heat exchanger element or a proximity of fins of an adjacent heat exchanger element.

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. 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. The first diffuser is joined to the exterior facing surface, and this joint is sealed. A cap surface of the first diffuser encloses the first opening and caps the coolant channel. The first diffuser is joined to a first header plate, which separates the first fluid from a second fluid within the coolant channel. A second diffuser defines a 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. The second diffuser is not fixedly attached to the housing and can move within the second opening.

A tank portion defines a space therein and has an opening on one side. A foot portion is in a plate shape extending radially outward from a bottom end of the tank portion on the one side. A core plate covers the opening and has a base portion and a holder portion. The base portion is in an elongated rectangular plate shape having first and second long lateral sides and a short lateral side. The holder portion includes a first holder at the first long lateral side, a second holder at the second long lateral side, and a third holder at the short lateral side, each gripping the foot portion. All the first holder, the third holder, and the second holder are one piece continuously extending along the first long lateral side, the short lateral side, and the second long lateral side.

A heat exchanger assembly includes first and second tanks having tube side walls, reservoirs formed therein, and apertures extending through the tube side walls. A flow tube having a plurality of fins on an exterior surface thereof, a first end, and a second end, the first end being received in an aperture of the first tank. A first seal is positioned between the flow tube and the first aperture. A retainer is positioned between the flow tube and the first aperture and between the first seal and the fins on the tube. A mounting block is positioned between the first tank and the fins on the tube, and is secured to the first tank. A second seal is positioned between the flow tube and the second aperture.

The present disclosure provides a liquid-cooling type double-sided cooler, including a first cooling portion and a second cooling portion. In the liquid-cooling type double-sided cooler, another end of the first cooling portion is formed with a first communication hole that is configured to penetrate the first cooling liquid path and an outside of the first cooling portion, another end of the second cooling portion is formed with a second communication hole that is configured to penetrate the second cooling liquid path and an outside of the second cooling portion; and the first cooling portion and the second cooling portion are positioned such that the first communication hole and the second communication hole face each other, and the first cooling liquid path and the second cooling liquid path are connected with each other.

The present invention relates to a condenser for condensing gasses. The condenser comprises: an inner tube (1) having a bore (3) therethrough; an outer tube (2) having a bore (8) therethrough and two ends, the inner tube (1) passing through the bore of the outer tube (2); and a seal (15, 16) at each end of the outer tube. The outer tube has exterior and interior fins and is sealed to the inner tube so as to define a sealed space (11) between the inner tube and the outer tube. The space (11) is adapted to contain a liquid in contact with the inner tube (1) and the outer tube (2). The invention further relates to a method of condensing a gas using the condenser, a process of making a chemical using the condenser and a kit adapted to be assembled into the condenser.
