An impact-resistant heat exchanger for a vehicle is provided with a region that does not transfer fluid but instead resists impacts from foreign objects, such as stones or debris. The heat exchanger includes first and second header tanks configured to contain a fluid to flow through the heat exchanger, as well as a tube extending between the header tanks. The tube has a fluid-transferring region fluidly coupling the first and second header tanks that is configured to transfer fluid between the first and second header tanks. The tube also has an impact-resistant region fluidly isolated from the fluid-transferring region and not fluidly coupling the first and second header tanks. The impact-resistant region has a rear edge adjacent the fluid-transferring region and an opposing leading edge.

A heat transport device includes a heat pipe having a capillary container having a wick and a working fluid arranged therein. A first heat source is coupled to a first end of the capillary container to define an evaporator section and a cold sink is coupled to a second end of the capillary container to define a condenser section. A capillary pump includes an evaporator and a reservoir configured to store an additional supply of working fluid. A second heat source coupled to the evaporator is configured to vaporize the working fluid arranged therein. A fluid loop couples the capillary pump to the heat pipe. Upon detection of a predetermined condition indicative that a majority of the working fluid within the heat pipe is frozen, the capillary pump is configured to supply vaporized working fluid to the heat pipe.

A tube stiffener for insertion into a plurality of radiator tubes includes a plurality of inserts and first and second connection strips. Each insert is configured to extend into at least one of the plurality of radiator tubes to strengthen the plurality of radiator tubes. The plurality of inserts include a first end and a second end and a tab projecting from each of the first end and the second end. The first connection strip is fixed to the tab on the first end and the second connection strip is fixed to the tab on the second end. Each of the connection strips connects the plurality of inserts to each other.

A vehicle air-conditioner safety device includes a controller which, in a case in which an abnormality has occurred in a heating device that heats coolant with a heater, determines whether or not the abnormality is a restorable abnormality or a non-restorable abnormality. When the abnormality is determined to be the restorable abnormality, it is determined whether or not the restorable abnormality has been removed. Heating by the heater is prohibited when the restorable abnormality or the non-restorable abnormality has occurred. Heating by the heater is restored when the restorable abnormality has been removed after heating by the heater is prohibited due to occurrence of the restorable abnormality.

A cross-flow heat exchanger for gas turbine engines which may be utilized to transfer heat from one fluid flow to a second independent fluid flow wherein one of the fluid flows has a high differential inlet pressure and temperature. The heat exchanger has robust construction to inhibit mixing of the fluid flows during a single burst duct event.

A core assembly for a plate-and-fin heat exchanger includes a pair of core plates and a heat-absorbing member disposed within the passageway that secures the pair of core plates together. The heat-absorbing member defines a plurality of fins that each include one or more bending points, and each bending point creates two points of contact between a core plate and the heat-absorbing member.

Some embodiments include a thermal management plane. The thermal management plane may include a top casing comprising a polymer material; a top encapsulation layer disposed on the top casing; a bottom casing comprising a polymer material; a bottom encapsulation layer disposed on the bottom casing; a hermetical seal coupling the bottom casing with the top casing; a wicking layer disposed between the bottom casing and the top casing; and a plurality of spacers disposed between the top casing and the bottom casing within the vacuum core, wherein each of the plurality of spacers have a low thermal conduction. In some embodiments, the thermal management plane has a thickness less than about 200 microns.

A heat exchanger includes a plurality of flat heat-transfer tubes and a corrugated fin placed between the plurality of flat heat-transfer tubes. Louvers in fin sections of the corrugated fin are divided into a first louver group formed further upstream in a direction of flow of air than a drain slit in the corrugated fin and a second louver group formed further downstream in the direction of flow of air than the drain slit. Plate portions of the first louver group and plate portions of the second louver group are inclined to a flat-plate portion in the fin sections and inclined in respective directions that are opposite to each other. The drain slit includes a plurality of drain slits formed between the first louver group and the second louver group at an interval in the direction of flow of air.

A corrugated fin of a heat exchanger is formed such that fin sections are joined together one after another in a tube axial direction of a plurality of flat heat-transfer tubes. Louvers in the fin sections of the corrugated fin are divided into a first louver group formed further upstream in a direction of flow of air than a drain slit in the corrugated fin and a second louver group formed further downstream in the direction of flow of air than the drain slit. Plate portions of the first louver group and plate portions of the second louver group are inclined to a flat-plate portion in the fin sections and inclined in respective directions that are opposite to each other. The drain slit includes a plurality of drain slits provided in a plurality of respective rows between the first louver group and the second louver group.

A conditioning apparatus for conditioning a gaseous medium to form a conditioned gaseous process medium having an inlet connection unit and an outlet connection unit, between which there is formed a flow path for gaseous medium having one or more conditioning stages, of which at least one has a heat exchanger. The heat exchanger has a heat exchanger chamber in which a heat exchanger element is at least partially accommodated and to which gaseous medium for conditioning can be supplied, wherein, in the heat exchanger, there are sensitive material regions which can be damaged by the gaseous medium. A heat exchanger protection system is provided by means of which such sensitive regions of the heat exchanger can be impinged on with a protective gas. Also specified are a method for conditioning a gaseous medium, and an installation and a method for treating workpieces.
