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.

A heat rejection system that employs temperature sensitive shape memory materials to control the heat rejection capacity of a vehicle to maintain a safe vehicle temperature. The technology provides for a wide range of heat rejection rates by actuation of the orientation or position of a heat rejection panel which impacts effective properties of the heat rejection system in response to temperature. When employed as a radiator for crewed spacecraft thermal control this permits the use of higher freezing point, non-toxic thermal working fluids in single-loop thermal control systems for crewed vehicles in space and other extraterrestrial environments.

The present invention relates to a heat exchanger for a motor vehicle provided on the front surface of an engine room of the vehicle, and, more particularly, to a heat exchanger for a motor vehicle including a sealing member provided on the circumference of the heat exchanger in order to prevent driving-induced wind from leaking to the outside of the heat exchanger without passing through the heat exchanger.

A heat exchanger includes fins each housed in a respective one of tubes. Each of the fins includes a connecting portion that corrugated for a predetermined fin pitch and that has peaks joined to an inner surface of a wall of each of the tubes and a non-connecting portion that is not joined to the inner surface of the wall of the each of the tubes. The non-connecting portion has a length longer than the predetermined fin pitch. The wall of the each of the tubes has a protrusion to face the non-connecting portion.

A water-cooling radiator includes a first water collection box, a second water collection box and a plurality of radiating pipes. A water pump chamber is disposed in a box body, and is in cooperation with a water pump, an impeller and a water pump cover to form. a water pump structure with good airtightness, so that the water pump and the first water collection box are effectively combined. The flow speed of water in the water-cooling radiator is effectively accelerated, which improves the heat dissipation efficiency. The overall heat dissipation effect of the product is very good.

Radiators, automobiles, and methods of transferring thermal energy to or from an automobile. The radiators include elongated, flattened tubes that transfer thermal energy while minimally affecting the reference area of the automobile, reducing the amount of drag produced by the radiator.

A tank for a radiator. The tank includes an inlet port through which coolant enters the tank. A wall at least partially defines a cavity in fluid communication with the inlet port. A curved surface of the wall is opposite to the inlet port and reduces volume of the cavity at the inlet port. The curved surface is configured to reduce turbulence of coolant flowing into the cavity from the inlet port. At least one turning vane extends along the wall into the cavity from the inlet port. The at least one turning vane is curved to reduce turbulence of coolant flowing through the inlet port and into the cavity.

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, a header is also included having such a profile. A cooler may also be provided, wherein the cooler has such a header.

In a clip for holding a tube element, a first fitting part is provided on one side surface of the clip, and a second fitting part is provided on the other side surface. A back surface holding part is provided on an open side of the clip, and a front surface holding part is provided on an unopened side. Furthermore, a tongue piece is provided between the back surface holding part and the front surface holding part.
