A stiffener for a heat exchanger includes a top plate and at least two legs extending from opposing sides of the top plate. Each of the at least two legs includes a bent portion, an angled portion, and a straight portion. The bent portion attaches the leg to the top plate. The angled portion increases a width of the stiffener from a width of the top plate. The straight portion extends perpendicular to a plane of the top plate.

A liquid receiver of a condenser has a liquid receiver main body and a plug removably fitted thereinto. The liquid receiver main body has a refrigerant inflow hole into which refrigerant flows from a condensation section and a refrigerant outflow hole from which refrigerant flows into a supercooling section. The liquid receiver has a first space formed above the upper end of the plug and communicating with the refrigerant inflow hole and a second space formed below the upper end of the plug and communicating with the refrigerant outflow hole. The plug has a flow passage which is open to the first space and the second space at opposite ends. The first-space-side opening of the flow passage is located below the refrigerant inflow hole. The flow passage has a throttle portion whose cross-sectional area is smaller than a hole area of the refrigerant inflow hole.

A heat exchanger system and method includes a securing frame, a heat transfer core having heat transfer panels removably secured to the securing frame, the heat transfer panels optionally including a plurality of segment modules coupled together, and one or more filter screens removably secured to the securing frame at one or both of an inlet end or an outlet end. The heat transfer core is disposed between the inlet end and the outlet end.

A heat dissipator includes a plate-shaped base portion that extends in a first direction along a direction where a refrigerant flows and in a second direction orthogonal to the first direction and has a thickness in a third direction, and fins that protrude from the base portion to one side in the third direction, extend in the first direction, are arranged in the second direction, and guide the refrigerant. A second of the fins is provided continuously on one side in the first direction that is a downstream side of a first of the fins, and a third fin that is provided continuously on another side in the first direction of the first fin, and includes an end on the one side in the third direction on the other side in the third direction.

A heat exchanger for a motor vehicle is provided. The heat exchanger contains at least one element that contains aluminum. This element that contains aluminum has a core and at least one plating layer. The core is composed of a first aluminum alloy that contains approx. 0.5% to approx. 4% by weight Mn, and approx. 0.5% to approx. 4% by weight Mg. The at least one plating layer is composed of at least one other aluminum alloy.

A cap (20) for a header box of a heat exchanger (1), in particular for a motor vehicle, in particular a radiator, is disclosed. This cap includes a head (21), a shank (22) comprising at least one mounting thread (23), this shank being between the head and a free end of the cap, a retaining lug (30), in particular elastically deformable, arranged to retain the cap in an opening (10) of the header box in an intermediate position of the cap, in which position the cap leaves a clear passage while being retained in the opening, this retaining lug being formed on the shank.

A profile for a header of a cooler which also includes numerous parallel tubes. The parallel tubes have a cross-sectional shape between slots for the tubes which further include at least two wave troughs Further, the header is also included having such a profile. A cooler may also be provided, wherein the cooler has such a header.

The present disclosure provides a drain valve for a heat exchanger. The drain valve includes a plug body and a locking member. The plug body extends in an axial direction and is configured to be inserted into a discharge port of the heat exchanger. The locking member is spaced away from the plug body in a radial direction of the plug body. The locking member is configured to engage with the discharge port when the plug body is inserted into the discharge port.

A method for monitoring that includes the steps of: associating a monitoring module with a heat exchanger unit; operating the monitoring module whereby a microcontroller performs various tasks, and ultimately providing an indication; and taking an action based on the indication. The monitoring module includes an at least one sensor proximate to the cooling side. The module also includes a logic circuit having a microcontroller in operable communication with the at least one sensor.

In cooling/heating cycles of a heat exchanger, to prevent cracks that tend to occur in a brazed portion between an end portion of a horizontal cross-section of a tube and a header plate. An end portion cover body is provided for an end portion of a tank main body or a header to cover hereby an end portion in a longer side direction of an opening end portion of a flat tube.
