A cooling module is coupled to an engine system and a Rankine cycle waste heat recovery system. The cooling module includes a heat exchanger for cooling a fluid of the engine system and a condenser for cooling a working fluid of the Rankine cycle waste heat recovery system, both of which extend in a width direction of the cooling module and are porous to a flow of cooling air in a depth direction of the cooling module. The condenser includes a first tubular header that extends in a height direction of the cooling module. A working fluid transfer tube fluidly couples the first tubular header to the Rankine waste heat recovery cycle system. The working fluid transfer tube has a first portion extending in the depth direction and a second portion extending in the height direction, the second portion being adjacent to the first tubular header in the width direction.

A vehicle is provided which includes an engine and a radiator. The radiator with circulating coolant fluid includes a plurality of embedded heat pipes each having (a) a body with first and second opposing ends, (b) a wicking material, and (c) a thermal transfer fluid, wherein said body of said heat pipe encloses an interior volume, and wherein said wicking material and said working fluid are disposed in said interior volume of said heat pipe. The first end of the heat pipe extracts heat from the engine, and the second end of the heat pipe transfers heat from the heat pipe to an atmosphere external to the engine. The heat transfer fluid transfers heat from the first end of said heat pipe to the second end of said heat pipe, and the wicking material transfers the heat transfer fluid from the second end of the heat pipe to the first end of the heat pipe.

Heat exchanger comprising a pair of headers and a plurality of parallel and coplanar tubes interconnecting the headers, wherein each header comprises a header plate provided with a plurality of slots, in each of which an end of a respective tube is fitted, and wherein the heat exchanger is configured to prevent fluid from flowing into at least one tube, hereinafter dummy tube, arranged at a boundary between functionally different sections of the heat exchanger. The slot of the header plate which receives the end of the respective dummy tube is formed as a blind recess in the header plate.

The invention relates to a heat exchanger, notably for a motor vehicle, said exchanger comprising a core bundle for the exchange of heat between a first and a second fluid, said core bundle comprising a plurality of tubes (3) and a header tank (2), said tubes (3) and said tank (2) allowing said first fluid to circulate between them, said exchanger further comprising a retaining plate (16) for holding said tubes (3), said plate (16) being fixed to said tank (2), said tank (2) comprising a collector plate (6) provided with orifices through which said tubes (3) pass, said collector plate (6) being made of plastic.

The invention also relates to a method of manufacturing such an exchanger.

Header plate for a heat exchanger, comprising a wall (3) provided with orifices (7), and through which tubes (1) arranged in rows in a longitudinal direction (L) are intended to pass, characterized in that: said wall has (3), in cross section, a profile made up of a central portion (13) and of two lateral portions (15), the lateral portions (15) overall follow a first curve with a first radius of curvature (R1), the central portion (13) overall follows a second curve with a second radius of curvature (R2), smaller than the first radius of curvature (R1).

The present invention relates to a heat exchange device (10) for a motor vehicle including a heat exchanger (12) with first and second collector plates (26; 28), first and second header boxes (30; 56) attached to the collector plates (26; 28) and a bundle (18; 20) of pipes (22) extending between the first and second collector plates (30; 56). Each of the collector plates (30; 56) forms a groove (54; 72) between the pipes (22) of the pipe bundle (18; 20) and a lateral end (50; 68) of the respective collector plate (30; 56). A perforated protective device (14) for the pipes (22) is attached to the heat exchanger (12) using attachment means (78, 80) bearing against the inside of the grooves (54, 72) in the first and second collector plates (26; 28).

A radiator assembly for a machine is provided. The radiator assembly includes an inlet tank adapted to receive a coolant. The radiator assembly includes a fluid line having a first end fluidly coupled to the inlet tank. The fluid line is adapted to allow passage of the coolant therethrough. The radiator assembly also includes an outlet tank fluidly coupled to a second end of the fluid line. The outlet tank is adapted to receive the coolant from the fluid line. The radiator assembly further includes a pressure compensating device fluidly coupled to at least one of the inlet tank and the outlet tank.

A product is provided with a container holding a heat storage medium. A fluid is entrained in a conduit that is routed through the container and routed through a heat generating system. An initiator is operably connected to the container. The heat storage medium is responsive to the generation of a signal from the initiator. When the heat generating system is in operation, the fluid is moved through the conduit so that when the heat generating system is operating, heat generated as a by-product is entrained in the fluid, passed through the container via the conduit and transferred to the heat storage medium. When desirable to provide heat to the heat generating system, the initiator is operated to expose the heat storage medium to a signal triggering the release of heat from the heat storage medium that is transferred through the fluid to the heat generation system.

The invention relates to a heat exchange module (402) for a motor vehicle, comprising: a first heat exchanger (404) comprising at least a first stage (404a) and a second stage (404b), said first heat exchanger being configured such that the first and the second stages are in fluid connection within the same cooling circuit (600) of the motor vehicle; a ventilation device (408) comprising at least one tangential fan (410) for setting in motion an air flow (F) intended to pass through the first heat exchanger (404), and wherein the first (404a) and second (404b) stages of the first heat exchanger (404) are arranged opposite each other, one behind the other with respect to the direction of flow of the air flow (F), so that the air set in motion by the tangential fan (410) successively passes through the first stage (404a) and then through the second stage (404b).
