PIPE CONNECTION STRUCTURE, COOLING SYSTEM, AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress generation of fluid pressure loss in a fitting portion in which a pipe is fitted into a tube.SOLUTION: A pipe connection structure 40 includes: a pipe 42; and a tube 44 having elasticity and connected to the pipe 42. The tube 44 includes: a connecting part 46 into which the pipe 42 is inserted and fitted; and a main body 48 continuous to the connecting part 46. The main body 48 includes a convex portion 50 protruding inward of an inner circumferential surface of the connecting part 46 in a radial direction of the tube 44. The convex portion 50 is formed annularly along a circumferential direction of the main body 48 and formed from one end to the other end of the main body 48 in an axial direction.
