Abstract: The present invention relates to a vehicle cooling module in which a plurality of unit modules is coupled by means of a fastening part and a connection bracket, and more particularly, to a vehicle cooling module including a fastening part that pulls a connection bracket, which is inserted into a hollow portion, to an inner wall to prevent the connection bracket from being damaged by an external force or vibration.

Abstract: The present invention relates to a pipe connection assembly of a heat exchanger for connecting a header tank and a pipe of the heat exchanger, in which a means for preventing a welding ring that fixes a manifold and a pipe from entering into a hollow at one end of the manifold before welding is disposed, and a space is formed between the inner surface of the one end of the manifold and the outer surface of the pipe, thereby preventing the molten welding ring from flowing out.

Abstract: A heat exchanger having an optimum design considering a thermal capacity of an end portion of an extrusion tube to significantly improve heat transfer performance by optimizing a shape and a thickness of the end portion of the tube, and a heat exchanger having an optimum design obtained based on a structured rule to enable easy application to other tubes with various dimensions. The heat exchanger has an end portion of a tube has a cross section in a quadrangular shape with rounded corners, each having a radius in a range of 15% to 45% of a height of the tube.

Abstract: Provided is a heat exchanger having an optimum design considering a thermal capacity of an end portion of an extrusion tube to significantly improve heat transfer performance by optimizing a shape and a thickness of the end portion of the tube. Provided also is a heat exchanger having an optimum design obtained based on a structured rule to enable easy application to other tubes with various dimensions.

Abstract: Provided is a heat exchanger having an optimal design satisfying appropriate pressure resistance and manufacturing characteristics, as well as maximizing heat transfer performance in an internal wall thickness, an outer wall thickness, and the number of holes of an extruded tube. Another embodiment of the present invention is directed to providing a heat exchanger having an optimal design formed based on a more systematic rule so as to be easily applied to tubes of various sizes.

Abstract: The present invention relates to a catalytic device and a vehicle air conditioning apparatus comprising the same and, more particularly, provides a catalytic device comprising: a case (140); a light source part (120) disposed to face an inner side of the case (140) so as to radiate light toward an inner surface of the case (140); and a catalyst part (130) which is disposed on the inner surface of the case (140) and in which a photocatalytic reaction is induced by light radiated from the light source part (120), wherein the catalyst part (130) is located at a first separation distance (L) from the light source part (120) in order that a maximum light energy (Pmax) of the light source part (120) is focused thereon.

Abstract: Provided is a tube for a heat exchanger, and more particularly, a tube for a heat exchanger forming a channel of a heat exchange medium and including a plurality of inner holes having inner spaces separated in a width direction by a plurality of inner walls extending in a longitudinal direction, in which a thickness of outer walls of certain regions at both ends in the width direction of the tube is formed to be thicker than that of the remaining regions, thereby improving heat exchange performance and preventing corrosion.

Abstract: An oil cooler includes a pair of spaced inlet/outlet boss portions; an inlet pipe and an outlet pipe coupled to the inlet/outlet boss portions, respectively; and tubes coupled to the inlet/outlet boss portions through both ends thereof to form an oil flow passage. The tubes are disposed in parallel and in a multi-stage arrangement. Each tube has a portion in fluid flow relationship with the neighboring tube at an area between the inlet and outlet pipes so oil can flow between them.

Abstract: Disclosed is a cooling system for a vehicle, in which coolant coolant, a blend of an antifreezing solution and water flowed into a radiator generates turbulent flow when a vehicle is in a state of a critical driving mode of a vehicle for example, a hill-climbing mode, thereby enhancing heat radiating performance and reducing pressure drop amount at the same time.
