Abstract

A piping connection structure includes: a pipe; and an elastic tube connected to the pipe, the tube including a connection into which the pipe is inserted and fitted, and a main body linked seamlessly with the connection, wherein the main body includes a projection that is formed circularly along a circumferential direction of the main body, and across the main body in an axial direction, and projects into an inside of the tube in a radial direction with respect to an inner periphery of the connection.

Claims

1. A piping connection structure comprising:

a pipe; and

an elastic tube connected to the pipe, the tube including

a connection into which the pipe is inserted and fitted, and

a main body linked seamlessly with the connection,

wherein the main body includes

a projection that is formed circularly along a circumferential direction of the main body, and across the main body in an axial direction, and

projects into an inside of the tube in a radial direction with respect to an inner periphery of the connection.

2. The piping connection structure according to claim 1,

wherein an inner periphery of the main body is arranged flush with an inner periphery of the pipe.

3. The piping connection structure according to claim 1,

wherein the tube further includes a gap filler that projects from a corner on a connection side of an end of the projection, and is formed circularly along the circumferential direction of the projection, and

wherein the gap filler is disposed in a gap between the inner periphery of the main body and the inner periphery of the pipe.

4. The piping connection structure according to claim 1,

wherein an end of the gap filler comes into contact with an end surface on a projection side of the pipe.

5. The piping connection structure according to claim 1,

wherein in a status before the pipe is fitted into the connection, the projection has a specific cross section across the main body in the axial direction.

6. The piping connection structure according to claim 1,

wherein in the status before the pipe is fitted into the connection, an outer shape of the tube has a specific cross section across the tube in the axial direction.

7. The piping connection structure according to claim 1,

wherein the tube is made of rubber or plastic.

8. The piping connection structure according to claim 1,

wherein a pair of the pipes are provided, and

wherein the connection is formed at each end of the tube in the axial direction.

9. A cooling system comprising:

a first unit and a second unit each including a pipe; and

a tube that connects a pair of the pipes and circulates a coolant between the first unit and the second unit, the tube including

a pair of connections into which a pair of the pipes are inserted and fitted, and

a main body formed between a pair of the connections,

wherein the main body includes

a projection that is formed circularly along a circumferential direction of the main body, and across the main body in an axial direction, and

projects into an inside of the tube in a radial direction with respect to inner peripheries of a pair of the connections.

10. Electronic equipment comprising:

a heating element; and

a cooling system that cools the heating element, the cooling system including

a first unit and a second unit each including a pipe, and

a tube that connects a pair of the pipes and circulates a coolant between the first unit and the second unit,

wherein the tube includes

a pair of connections into which a pair of the pipes are inserted and fitted, and

a main body formed between a pair of the connections, and

wherein the main body includes

a projection that is formed circularly along a circumferential direction of the main body, and across the main body in an axial direction, and

projects into an inside of the tube in a radial direction with respect to inner peripheries of a pair of the connections.
