The line assembly 300a can be used for the circulation of gaseous and/or liquid media, in particular for the circulation of coolant. The pipe assembly 300a may be used not only in the cooling system 300 for the battery, but also in the cooling system for other devices, or in a pipe system in which a plurality of fluid media are required to be circulated at the same time.

The cross-sectional shape of the tube 311 can be various, such as circular, square, triangular, wavy or elliptical, and the like, and the shape of the tube 311 can be adjusted according to the required internal space requirement. In some embodiments, the tube 311 may be a curved tube with a circular cross section, and the radius of the outer axis fillet at the corner is greater than 1 times the outer diameter of the tube 310, so as to facilitate the manufacturing of the tube 310.

The first separating portion 312 is disposed in the tube body 311, and the first separating portion 312 can be used for separating an inner space of the tube body 311, and it can be understood that the first separating portion 312 can extend from one end of the tube body 311 to the other end of the tube body 311, so that the inner space of the tube body 311 can be separated into a plurality of first channels 313, and each of the first channels 313 can communicate with two ends of the tube body 311.

The shape of each second channel 324 may be the same or different. The number of first channels 313 corresponds to the number of second channels 324.

The connecting portion 322 may be disposed on the body 321, and the two may be processed into an integral piece by an integral forming process, or the connecting portion 322 and the body 321 may be different components, and the two are fixedly connected by a common connecting manner.

With continued reference to fig. 5 and 6, according to some embodiments of the present application, the connection portion 322 includes a plurality of sub-connection segments 322a disposed on the body 321, each sub-connection segment 322a is inserted into one first channel 313, and a sub-channel 322c for communicating one first channel 313 and one second channel 324 is disposed inside each sub-connection segment 322 a.

The sub-connection section 322a may be connected to the body 321 by a conventional connection means, or the sub-connection section 322a may be processed as a single body with the body 321 by an integral molding process.

The number of the sub-connection segments 322a may correspond to the number of the first channels 313, i.e., each sub-connection segment 322a is disposed corresponding to one first channel 313.

Each sub-connecting section 322a may also be a hollow structure, that is, the sub-connecting section 322a has a sub-channel 322b therein, and one end of the sub-channel 322b may be connected to a second channel 324 in the body 321, and the other end may be connected to a first channel 313.

In addition, the cross-sectional dimension of each sub connection segment 322a, taken as a cross-section of the sub passage 322b in a section perpendicular to the communication direction of the sub passage 322b, may be smaller than or equal to the cross-sectional dimension of the first passage 313 to which it is connected, thereby enabling the sub connection segment 322a to be inserted into the first passage 313.

By arranging the sub-connecting section 322a capable of being inserted into the first channel 313, the connection between the pipeline 310 and the pipeline connector 320 can be facilitated, and the communication between the first channel 313 and the second channel 324 can be realized, so that the structure is simple and easy to realize.

In some embodiments, the outer surface of each sub-connecting section 322a is in interference fit connection with the channel wall of the first channel 313 in which the sub-connecting section 322a is inserted.

It can be understood that the cross-sectional dimension of the outer surface of the sub-connection section 322a may be slightly larger than the cross-sectional dimension of the first channel 313 into which the sub-connection section 322a is inserted, so that after the sub-connection section 322a is inserted into the first channel 313, the outer surface of the sub-connection section 322a can clamp the channel wall of the first channel 313, which is beneficial to achieve the sealing between the two, and improve the condition that the fluid medium is easy to leak from between the sub-connection section 322a and the channel wall of the first channel 313.

In some embodiments, the maximum cross-sectional area of the sub connection section 322a is equal everywhere in a cross section perpendicular to the communication direction of the sub passage 322 b.

The communication direction of each sub-connection section 322a may be the flow direction of the fluid medium in the sub-connection section 322a, and the maximum cross-sectional area of the sub-connection section 322a being equal everywhere may mean that the sub-connection section 322a has a constant cross-sectional structure, i.e., the shape and size of any cross-section along the communication direction thereof are the same.

The structure is simple, the processing is easy, the contact area between the sub-connecting section 322a and the channel wall of the first channel 313 can be increased, and the sealing effect of the pipeline assembly 300a is improved.

In some embodiments, the maximum cross-sectional area of the sub connection section 322a is gradually decreased in a direction from the second passage 324 toward the first passage 313, in a cross section perpendicular to the communication direction of the sub passage 322 b.

It will be appreciated that the sub-connecting segment 322a may be of a variable cross-sectional configuration, i.e., the maximum cross-sectional area may decrease from one end proximate the second passageway 324 to the other end proximate the first passageway 313, for example, the sub-connecting segment 322a may be of a tapered or wedge configuration.

The sub-connecting section 322a is configured to have a variable cross-section structure, so that it can play a guiding role to facilitate the insertion of the sub-connecting section 322a into the first channel 313.

In some embodiments, the connecting portion 322 further includes a mounting portion 322c disposed on the body 321, the mounting portion 322c is disposed around the plurality of sub-connecting sections 322a, and a groove 325 for accommodating a portion of the pipeline 310 is formed among the body 321, the mounting portion 322c and the plurality of sub-connecting sections 322 a.

Referring to fig. 6, the sub-connecting sections 322a and the mounting portion 322c may be connected to a surface of the body 321, and the mounting portion 322c may be a ring structure, which may be sleeved outside the sub-connecting sections 322a, so that a groove 325 may be defined between the sub-connecting sections 322a, the mounting portion 322c, and the surface of the body 321.
