DOUBLE PIPE HEAT EXCHANGER HAVING MULTI-DIRECTIONAL CONNECTOR AND AIR CONDITIONER FOR VEHICLE HAVING THE SAME

摘要

PURPOSE: A double pipe heat exchanger with a multi-directional connector and a cooling device for a vehicle with the same are provided to improve heat exchange efficiency between fluids flowing in an inner pipe and the gap between the inner pipe and an outer pipe. CONSTITUTION: A double pipe heat exchanger with a multi-directional connector comprises an outer pipe(100), an inner pipe, a first fluid supply pipe(400), and a connector. Multiple protrusions are formed on the inner surface of the outer pipe. The inner pipe is inserted into the outer pipe. The first fluid supply pipe is welded to one end of the inner pipe. The connector has a space for receiving the outer and inner pipes and the first fluid supply pipe therein. The connector comprises first and second blocks(310,320). The first block has first and second openings and a first connection path. The first connection path has a space where the inner pipe and the first fluid supply pipe are welded. The second block is formed on the top of the first block and has three or more side surfaces having different directions.
