A heat exchanger tube insert for use in a heat exchanger tube located within a fuel fired apparatus or non-fired storage tank heat exchanger. The heat exchanger tube insert comprise a central rod, a cap, and at least two protruding helical guides that are configured to direct a flow of heated working fluid around the inner circumference of the heat exchanger tube.

Provided is a heat exchanger. The heat exchanger includes a plurality of refrigerant tubes in which a refrigerant flows, a heatsink fin coupled to the plurality of refrigerant tubes to heat-exchange the refrigerant with a fluid, a header disposed on at least one side of the plurality of refrigerant tubes to define a flow space of the refrigerant and a guide device disposed in the header to partition the flow space, the guide device guiding the refrigerant from the header to the refrigerant tubes. The guide device includes a movable cover part.

A transmission-mountable transmission cooler and method of installing and manufacturing the same is provided. The transmission cooler is adapted to couple directly to the transmission via a power take-off aperture typically found on manual truck transmissions. As a result, the transmission cooler may be made from an extruded aluminum piece to which tool and die making has provides a bolt pattern that matches the bolt pattern of a standard power take-off cover of the power take-off aperture, resulting in a cost-effective method of installation and in turn manufacture.

A first connection portion is located on one side of a predetermined flow path member in a plane direction. The predetermined flow path member and another flow path member are bonded by brazing at the first connection portion. A second connection portion is located on the other side of the predetermined flow path member. The predetermined flow path member and another flow path member are bonded by brazing at the second connection portion. A brazing material layer extends over the predetermined flow path member, the first connection portion, and the second connection portion. A hilling portion is a portion of the predetermined flow path member. The hilling portion is curved to protrude toward a side on which the blazing material layer is provided. The hilling portion extends along a direction in which the first connection portion or the second connection portion extends.

A method of operating a RAM inlet header (RIH) is provided. The method includes determining a temperature of RAM air flows in a body through which RAM air flows from an inlet toward a heat exchanger, determining a temperature of excess air for use in an environmental control system (ECS) and, in an event the temperature of the excess air is less than the temperature of the RAM air flows, directing a curtain of the excess air from a nozzle body and along a wall of the body into flows of the RAM air and toward the heat exchanger.

The present disclosure relates to a heat exchanger. The heat exchanger includes: a plurality of tube panels including a tube elongated in one direction; a pair of header modules coupled to both ends of the plurality of tube panels; and a pair of header cases having an open side, providing a space therein, and having the header module inserted in the space such that the tube panels communicate with the spaces, in which the header modules is composed of a plurality of header blocks stacked and coupled to each other, and an insertion hole in which the tube panel is inserted is formed at each of the plurality of header blocks. Accordingly, it is possible to increase the efficiency of manufacturing a heat exchanger, manufacture a heat exchanger flexibly in a custom-made type in accordance with the size of a product having the heat exchanger, reduce tolerance due to brazing, and improve stability of a product.

A heat exchanger for heat transfer between an external first flow along a first flowpath and a second flow along an internal second flowpath, has: a first manifold; a second manifold; and a plurality of tubes extending from the first manifold to the second manifold and having respective interiors bounding respective legs of the second flowpath. The plurality of tubes comprises a plurality groups of tubes. For each of the groups of the tubes: the tubes of the group have first ends mounted to the first manifold at respective first locations; and the tubes of the group have second ends mounted to the second manifold at respective second locations. From the first manifold to the second manifold, each tube has: a upstream concave first turn; an upstream convex second turn; and an upstream concave third turn; and the second locations are offset downstream along the first flowpath from the respective first locations.

A side member for a heat exchanger includes a core formed of tubes stacked with one another along a stacking direction. The heat exchanger performs heat exchange between a first fluid flowing through the tubes and a second fluid passing through the core. The side member includes a body portion. The body portion has an elongated shape extending along a longitudinal direction and is configured to be positioned on one side of the core in the stacking direction in parallel with the tubes. The body portion defines a channel therein extending along a longitudinal direction and is configured to allow the first fluid to flow through the channel while exchanging heat with the second fluid passing through the core.

A water-cooling head includes a casing, a base, an input channel, an output channel and a pump. An active space is defined by the base and the casing collaboratively. A working medium is filled in the active space. The heat absorbed by the base is transferred to the working medium. The input channel is in communication with the active space. The cooled working medium is introduced into the active space through the input channel. The output channel is in communication with the active space. The heated working medium is outputted from the active space through the output channel. The pump is installed on the casing, and includes an impeller. The impeller is disposed within the active space and located near the output channel. The impeller is driven to guide the working medium to be outputted from the active space through the output channel.

A water-cooling head includes a casing, a base, a thermal conduction structure and a pump. An active space is defined by the base and the casing collaboratively. A working medium is filled in the active space. The pump includes a fixing element, a shaft and an impeller. After the fixing element is fixed, the fixing element is contacted with the base or contacted with the thermal conduction structure, and the shaft is fixed on the fixing element. Consequently, the impeller is stably rotated about the shaft, and the performance and the reliability of the water-cooling head are enhanced.
