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.

A heat exchanger module having at least two fluid circuits, of longitudinal axis including a stack of plates, defining at least two fluid circuits, at least a part of the plates each including fluid circulation channels, the channels of at least one of the two circuits, referred to as first circuit, having at least one fluid supply and distribution zone for supplying and distributing fluid from outside the stack, forming a fluid pre-header, in which zone the channels are delimited by studs distributed over the surface of the plate; an exchange zone continuous with the pre-header and wherein the channels are each delimited by a groove separated from one another by a rib and extending along the longitudinal axis.

A radiator for a vehicle is provided. The radiator includes a first header tank that has an inlet port formed at a first side thereof to allow a coolant to flow from an engine thereinto and an outlet port formed at a second side thereof to allow the coolant to flow to the engine. A second header tank is disposed apart from the first header tank. A heat-exchanging portion fluidly connects the inlet tank and the outlet tank and includes a plurality of tubes and radiation fins to cool the coolant flowing in the tubes by exchanging heat with air. A diaphragm unit is disposed at the inside of the first header tank to prevent the coolant which flows into the inlet port from being mixed with the coolant which is exhausted from the outlet port.

Modular flow control systems include several differently-shaped structures to achieve desired flow characteristics in fluid flow. Systems include one or many plates held in desired positions by a retainer within the flow. The plates are uniquely shaped based on their position, or vice versa, to shape flow in a desired manner. The plates may fill an entire flow area or may extend partially throughout the area. Plates can take on any shape and are useable in systems installed in any type of flow conduit. When used in a PCCS upper manifold in a nuclear reactor, a chevron plate directly below the inlet divides flow along the entire upper manifold. Perforated plates allow flow to pass at ends of the PCCS upper manifold. The plates can be installed along a grooved edge during an access period and held in static position by filling the length of the PCCS upper manifold.

The invention discloses a liquid cooling radiator for liquid coolers, which includes a shunt box, a liquid collection box and heat dissipation pipes connected between the shunt box and the liquid collection box. The inside of the shunt box is divided into a hot liquid inlet chamber and a cold liquid outlet chamber by a heat-resistant space. The heat-resistant space is composed of a hot liquid baffle and a cold liquid baffle combined in the shunt box at intervals to form the heat-resistant space between the hot liquid baffle and the cold liquid baffle, which can prevent the hot liquid baffle and the cold liquid baffle from contacting each other to transfer heat, and prevent the cooled cold liquid from being affected by the hot liquid before flowing out of the liquid cold row, causing the problem of heating up.
